Yes, builders’ risk insurance is needed for most renovations, particularly when the project exceeds 10% of your home’s dwelling value, involves structural changes, requires financing, or leaves your property vacant for more than 60 consecutive days. Standard homeowners insurance policies contain vacancy clauses and renovation exclusions that create dangerous gaps in coverage during construction projects.
The Insurance Services Office (ISO), which sets industry-standard policy forms, establishes specific language in homeowners policies that limits or eliminates coverage when properties undergo major renovations. Most homeowners policies include a vacancy provision that excludes coverage for vandalism, water damage, theft, and sprinkler leakage if a dwelling remains vacant for more than 60 consecutive days before a loss occurs. This creates an immediate problem because renovations often require homeowners to vacate their properties, leaving them without the protection they assume their existing policy provides.
The U.S. construction insurance market reached $13.9 billion in 2024, growing at a 5.8% annual rate, driven by increased awareness of coverage gaps and stricter lender requirements. Property owners face significant financial exposure during renovation projects, with claims volume increasing 36% in 2024 according to Verisk Analytics data.

Understanding Builders’ Risk Insurance for Renovations
Builders’ risk insurance is a specialized property insurance policy that covers buildings, structures, materials, fixtures, and equipment during construction or renovation. Unlike permanent property insurance, builders’ risk policies provide temporary coverage specifically designed for the unique exposures that exist during active construction projects. The coverage protects against physical loss or damage from covered perils such as fire, wind, theft, and vandalism.
Standard homeowners insurance policies are designed to protect completed, occupied homes. These policies contain specific language that either excludes or severely limits coverage when a home undergoes major renovation work. Insurance carriers structure homeowners policies this way because construction activities dramatically increase the risk of loss compared to occupied homes.
The Legal Framework: When Builders’ Risk Is Required
Lender Requirements Under Loan Agreements
When you finance a renovation project through a construction loan, home equity loan, or refinance with renovation proceeds, your lender will require builders’ risk insurance as a condition of the loan agreement. This requirement appears in the loan documents as a mandatory clause that must be satisfied before the lender disburses funds. Banks and mortgage companies make this requirement because the unfinished building serves as collateral for the loan.
The lender typically requires you to name them as a loss payee or mortgagee on the policy. This designation means that if a covered loss occurs, the insurance proceeds go to the lender first, protecting their financial interest in the property. Without builders’ risk coverage in place, your lender will not close the loan, effectively preventing your renovation project from moving forward.
Lenders require coverage for the total hard cost of the construction project. Some lenders also require soft cost coverage, which protects against expenses like additional loan interest, permit fees, and professional fees that accumulate when a covered loss delays project completion. The policy limit must equal or exceed the total loan amount to satisfy most lender requirements.
Building Permit Requirements
Many municipalities across the United States require proof of builders’ risk insurance before issuing a building permit. This requirement exists at the city and county level rather than as a federal mandate. Local building departments implement this requirement to ensure that property owners have financial protection in place before beginning construction that could potentially damage neighboring properties or create public safety hazards.
The building permit application process typically includes a section where you must provide evidence of insurance coverage. The building department may require a certificate of insurance naming the municipality as an additional insured or certificate holder. Without this documentation, the building department will not issue the permit, and you cannot legally begin work.
Some jurisdictions have specific minimum coverage amounts that must be met. These minimums often relate to the estimated project value declared on the permit application. Building inspectors may verify that coverage remains in force throughout the construction period during routine inspections.
Contractual Obligations in Construction Agreements
Construction contracts between property owners and general contractors almost always include language requiring one party to purchase and maintain builders’ risk coverage. The contract specifies who bears responsibility for purchasing the policy — either the owner or the contractor. It also establishes minimum coverage amounts, required endorsements, and who must be named as additional insureds.
When the contractor purchases the policy, property owners should carefully review the coverage to ensure it adequately protects their interests. Contractors may purchase policies with lower limits or more restrictive terms to save money, leaving owners exposed to uninsured losses. The construction contract should specify that the owner has the right to review and approve the policy before work begins.
Most construction law experts recommend that property owners purchase builders’ risk policies themselves rather than relying on contractor-procured coverage. This approach gives owners direct control over coverage limits, endorsements, and claims handling. When owners control the policy, they ensure that insurance proceeds are used to rebuild rather than potentially being diverted to pay contractor debts.
The 10% Threshold Rule for Major Renovations
Homeowners insurance policies contain specific provisions that distinguish between minor renovations and major renovations. The insurance industry generally uses a 10% threshold based on the dwelling coverage limit to make this distinction. This threshold determines whether your existing homeowners policy will continue to provide adequate protection during renovation work.
How the 10% Rule Works
If your homeowners policy has a dwelling coverage limit of $500,000, renovations costing less than $50,000 (10% of the dwelling limit) are considered minor renovations. For these smaller projects, your homeowners insurance may continue to provide coverage, though you must notify your insurer before work begins. Renovations exceeding $50,000 are considered major renovations and trigger more restrictive policy provisions.
When renovations exceed the 10% threshold, several significant policy changes occur. First, the policy applies a special construction deductible equal to 5% of the dwelling limit rather than your standard deductible. Using the $500,000 dwelling limit example, your deductible increases from perhaps $1,000 to $25,000 for any losses occurring during the renovation period.
Second, claim settlements change from replacement cost to actual cash value less depreciation. Replacement cost coverage pays to rebuild your home using new materials at current prices. Actual cash value coverage deducts depreciation based on the age and condition of damaged property, resulting in significantly lower claim payments. A 20-year-old roof damaged during renovation might receive only 50% of replacement cost under actual cash value settlement.
Additional Factors Beyond the 10% Rule
Even if your renovation costs less than 10% of the dwelling limit, certain circumstances trigger the need for builders’ risk coverage. If your renovation requires you to move out of the home for any length of time, this creates vacancy exposure that most homeowners policies will not cover. The combination of vacancy and construction activity creates such elevated risk that carriers either exclude coverage entirely or charge substantial additional premiums.
Renovations that alter the home’s footprint, such as additions or structural modifications, also typically require separate builders’ risk coverage regardless of the total cost. These types of projects expose the existing structure to weather and other perils in ways that standard homeowners policies do not anticipate or price for.
High-value home insurers who specialize in luxury properties often have more stringent notification requirements. Some high-value homeowners policies require notification and approval for any renovation exceeding $500,000, regardless of what percentage that represents of the total dwelling limit.
The 60-Day Vacancy Clause Problem
Most homeowners insurance policies include a vacancy clause that drastically reduces or eliminates coverage when a dwelling remains vacant for more than 60 consecutive days. This provision creates a major problem for renovation projects because many renovations require homeowners to temporarily relocate while work progresses. The vacancy clause represents one of the most common reasons for claim denials during renovation projects.
What the Vacancy Clause Excludes
Under the standard ISO homeowners form, if your dwelling has been vacant for more than 60 consecutive days before a loss occurs, the policy completely excludes coverage for losses caused by:
- Vandalism and malicious mischief
- Glass breakage
- Water damage from plumbing, heating, or air conditioning systems
- Theft and attempted theft
For all other covered causes of loss, the vacancy clause does not exclude coverage, but damage to your property still creates problems because insurers may dispute whether proper protective measures were maintained.
Commercial property policies have even more restrictive vacancy provisions. These policies exclude the perils listed above and reduce payment by 15% for all other covered causes of loss, including fire, if the building has been vacant for more than 60 consecutive days.
The Construction or Renovation Exception
The vacancy clause contains a critical exception: buildings under construction or renovation are not considered vacant. This exception seems to solve the problem, but it creates new questions about what constitutes sufficient construction or renovation activity to prevent the vacancy clause from applying.
Courts have interpreted “under construction or renovation” to require substantial, continuous construction activity. Sporadic work or occasional contractor visits do not satisfy this requirement. In Farbman Group v. Travelers Insurance Companies, the court ruled against a property owner because the record failed to show that renovation efforts had occurred within the 60-day period before water damage from frozen pipes occurred.
To support a claim that your property was under construction or renovation and therefore not vacant, you need documentation showing:
- The number of workers on site and their work schedule
- The amount of time workers spent at the property
- What specific work was completed during the 60-day period before any loss
- Evidence of materials being delivered and used
- Permits pulled and inspections conducted
Property owners who plan renovations that require vacating the home face a choice: maintain substantial ongoing construction activity throughout the project, or purchase separate builders’ risk coverage that does not contain vacancy restrictions.
Coverage Comparison: Homeowners Insurance vs. Builders’ Risk
| Coverage Feature | Standard Homeowners Insurance | Builders’ Risk Insurance |
|---|---|---|
| Vacancy Protection | Excluded or limited after 60 days | No vacancy exclusion during construction |
| Construction Deductible | 5% of dwelling limit ($25K on $500K home) | Standard deductible ($1K-$5K typical) |
| Settlement Basis During Work | Actual cash value (depreciated) | Replacement cost for renovations |
| Materials in Transit | Not covered | Covered in transit to jobsite |
| Materials Before Installation | Limited or excluded | Fully covered at jobsite |
| Soft Costs Coverage | Not included | Available (typically 10% of value) |
| Contractor Theft/Vandalism | May be excluded | Covered with proper endorsement |
| Policy Period | Annual, continuous | Project-specific (3, 6, 9, or 12 months) |
Existing Structure Coverage: Actual Cash Value vs. Replacement Cost
When you purchase builders’ risk insurance for a renovation project, you face an important decision about whether to include coverage for the existing structure or cover only the renovation work itself. This decision has significant financial implications, and many property owners misunderstand how builders’ risk policies value existing structures.
The Actual Cash Value Problem
Most builders’ risk insurers provide coverage for existing structures being renovated only on an actual cash value (ACV) basis, not replacement cost. Actual cash value equals replacement cost minus depreciation. Depreciation accounts for the age, condition, and remaining useful life of building components.
The depreciation calculation can result in claim payments that are 30% to 50% lower than replacement cost. A 20-year-old roof with a 25-year expected lifespan has 80% of its useful life exhausted. If fire damages this roof during renovation and replacement cost is $40,000, the ACV settlement would be only $8,000 (20% of replacement cost), leaving you to pay $32,000 out of pocket.
This valuation method creates particular problems for older homes undergoing renovation. The existing portions of a 50-year-old home may be heavily depreciated, resulting in very low ACV settlements if damage occurs. Property owners who do not understand this limitation often purchase insufficient coverage and face substantial out-of-pocket costs after a loss.
Calculating Proper Values
When including existing structure coverage in a builders’ risk policy, you must calculate and specify separate values for the existing structure and the renovation work. Do not combine these values or use the property’s market value or purchase price.
To determine existing structure value, use replacement cost valuation tools such as Marshall & Swift calculators. Calculate what it would cost to rebuild the existing structure at current prices using current building codes. Then multiply this replacement cost by the depreciation factor based on the structure’s age and condition to arrive at actual cash value.
For the renovation portion, calculate the total completed value including all materials, labor, and contractor profit. This value should represent what the renovation will be worth when finished, not just the current construction phase value. Undervaluing the renovation portion can trigger coinsurance penalties that reduce claim payments.
The Option to Exclude Existing Structures
Some property owners choose to purchase builders’ risk policies that cover only the renovation work and exclude the existing structure. This approach costs less because it eliminates the existing structure premium. It makes sense when you have other insurance coverage that adequately protects the existing building.
However, this approach creates risks. Your homeowners insurance may exclude or limit coverage once renovation work begins. General liability policies carried by contractors do not cover property damage to the work itself. If you exclude existing structure coverage from the builders’ risk policy, you may create a coverage gap where no policy responds to damage affecting the existing portions of your home.
Before excluding existing structure coverage, carefully review your homeowners policy language about renovations. Confirm in writing with your homeowners insurer that they will continue to cover the existing structure during the renovation period. Document this confirmation and keep it with your policy documents.
The Three Most Common Renovation Scenarios
Scenario 1: Major Kitchen and Bathroom Remodel in Occupied Home
| Project Details | Coverage Analysis |
|---|---|
| Scope: $150,000 complete kitchen and two bathroom renovations in $800,000 home (18.75% of dwelling value) | Exceeds 10% threshold: Triggers special construction deductible ($40,000) and actual cash value settlement under homeowners policy |
| Timeline: 12 weeks, homeowners remain in residence during construction | Vacancy clause does not apply: Property remains occupied, but homeowners policy still imposes construction restrictions |
| What’s at Risk: $100,000 in materials and fixtures staged at property before installation, $50,000 labor investment | Homeowners policy materials coverage: Limited to $2,500 off premises; materials before installation may be excluded |
| Best Solution: Purchase builders’ risk covering renovation only (existing structure excluded) for $1,500-$7,500 premium | Result: Standard deductible applies, replacement cost settlement, materials covered in transit and before installation, no vacancy concerns |
This scenario represents one of the most common renovation situations. Homeowners continue living in their home during the project, so vacancy is not an issue. However, the project exceeds 10% of the dwelling value, triggering the restrictive provisions in the homeowners policy.
The key exposure in this scenario involves the materials and fixtures purchased for the project. High-end kitchen cabinets, appliances, tile, and bathroom fixtures can easily total $50,000 to $100,000. Once delivered to the property but before installation, these materials face theft and damage risks that homeowners policies do not adequately cover.
A builders’ risk policy eliminates the special construction deductible, provides replacement cost settlement for the renovation work, and covers materials from the time they leave the supplier until they are permanently installed. The policy costs between 1% and 5% of the project value, or $1,500 to $7,500 for this $150,000 renovation.
Scenario 2: Structural Addition with Temporary Relocation
| Project Details | Coverage Analysis |
|---|---|
| Scope: $400,000 second-story addition on $600,000 home, requires complete roof removal | Major structural modification: Homeowners insurance likely excludes coverage once roof is removed, exposing structure to weather |
| Timeline: 8 months, homeowners move to rental apartment for full duration | Vacancy exceeds 60 days: Vacancy clause eliminates vandalism, theft, water damage, and glass breakage coverage under homeowners policy |
| What’s at Risk: Entire $600,000 existing structure plus $400,000 addition, total $1 million exposure | Complete exposure gap: Homeowners policy denies most claims; contractor’s general liability does not cover property damage to the work |
| Best Solution: Comprehensive builders’ risk policy covering both existing structure ($600,000 ACV) and addition ($400,000 replacement cost) with soft costs endorsement | Result: No vacancy restrictions, replacement cost for addition, ACV for existing structure, soft costs up to $100,000 (10% of completed value), premium $10,000-$50,000 |
This scenario presents the most significant insurance exposure because it combines structural modification with extended vacancy. The homeowners policy will deny virtually all claims once the home has been vacant for more than 60 days and the roof has been removed.
The roof removal creates particular vulnerability because it exposes the interior of the home to rain, wind, and other weather events. Even brief rainstorms can cause extensive water damage to framing, insulation, drywall, and contents. Without builders’ risk coverage, the property owner bears the entire loss personally.
The soft costs endorsement provides critical additional protection. If a covered loss delays project completion, soft costs coverage reimburses expenses such as extended rental costs, additional months of construction loan interest, extended general contractor overhead, and permit renewal fees. These costs can easily reach $50,000 to $100,000 during a multi-month delay.
Scenario 3: Historic Home Renovation with Lender Financing
| Project Details | Coverage Analysis |
|---|---|
| Scope: $750,000 comprehensive renovation of 100-year-old home using $500,000 construction loan | Lender requirement: Construction loan agreement mandates builders’ risk as condition of financing, must name lender as loss payee |
| Timeline: 14 months, property vacant throughout construction period | Extended vacancy: Homeowners policy excludes coverage; even vacancy permit endorsement may not cover this duration |
| What’s at Risk: $500,000 loan principal, $750,000 total project value, historic fabric of irreplaceable home | Multiple stakeholder interests: Owner, lender, general contractor, and potentially historic preservation board all have financial interests requiring protection |
| Best Solution: Owner-controlled completed value builders’ risk policy for $1,250,000 (existing structure ACV $500,000 + renovation $750,000) with extended period endorsement and possibly historic property coverage | Result: Satisfies lender requirements, protects owner’s equity, covers lender’s collateral interest, allows for project delays, premium $12,500-$62,500 (1-5% of total insured value) |
Historic home renovations present unique challenges because the existing structure may have significant value that cannot be replaced with modern construction methods. Some components of historic homes, such as original millwork, plaster, or architectural details, are irreplaceable at any cost.
Standard builders’ risk policies may not adequately address historic property concerns. Some insurers offer historic property endorsements that provide replacement with materials of like kind and quality, rather than modern substitutes. These endorsements may increase premiums but provide more appropriate coverage for properties with historic significance.
The extended project timeline creates additional exposure. Many builders’ risk policies have standard terms of 6, 9, or 12 months. Historic renovations often exceed these timelines due to the specialized nature of the work. Property owners must either purchase longer initial policy terms or request extensions before the original policy expires. Allowing a builders’ risk policy to lapse during construction creates a dangerous gap where no coverage exists.
Soft Costs Coverage: The Hidden Value
Soft costs represent the expenses you incur during construction that are not related to labor or building materials. When a covered loss damages your project and causes delays, these additional expenses accumulate quickly. Standard builders’ risk policies may include limited soft costs coverage, but most property owners benefit from purchasing a soft costs endorsement.
What Soft Costs Include
Soft costs typically covered by endorsement include:
Financial Costs: Additional construction loan interest, permanent loan interest if closing is delayed, real estate taxes during the extended construction period, insurance premiums for the extended period
Professional Fees: Architect fees for revised plans, engineer fees for structural reassessment, consultant fees for project management during recovery, legal fees related to the loss, accounting fees for financial analysis
Regulatory Costs: Building permit extension fees, re-inspection fees after repairs, licensing fees that must be renewed due to delays, code compliance costs if regulations change during the delay
Marketing Costs: Advertising expenses to announce revised opening dates, promotional materials that must be reprinted with new dates, lease commission fees if tenant recruitment must restart
Administrative Costs: Extended general conditions for contractor overhead, extended site supervision costs, additional project management fees, security costs during the extended period
How Soft Costs Coverage Works
Soft costs endorsements typically provide coverage equal to 10% of the completed value of the project. For a $1 million renovation, soft costs coverage would be $100,000. The coverage applies only when a covered loss under the builders’ risk policy causes a delay in project completion.
Most soft costs endorsements include a waiting period, commonly 30 to 90 days, before coverage begins. This waiting period recognizes that brief delays do not generate significant soft costs. After the waiting period expires, the policy reimburses soft costs until the project reaches completion or the policy limit is exhausted.
To recover soft costs, you must provide detailed documentation showing that the claimed expenses were directly caused by the covered loss. This requires maintaining careful records of all project-related expenses and being able to demonstrate the original project timeline compared to the delayed timeline resulting from the loss.
Real-World Soft Costs Example
A developer plans to convert an office building into residential condominiums. The $5 million project is financed with a construction loan at 8% annual interest. Four months before scheduled completion, an electrical fire destroys a significant portion of the work.
The fire damage itself costs $800,000 to repair. But the four-month delay generates substantial additional costs:
- Construction loan interest: $5 million × 8% ÷ 12 months × 4 months = $133,333
- Extended general contractor overhead: $25,000 per month × 4 months = $100,000
- Architect and engineer fees to revise plans and specifications: $45,000
- Building permit extension and re-inspection fees: $8,000
- Extended property insurance premiums: $6,000
- Marketing materials to be reprinted with revised opening date: $15,000
Total soft costs: $307,333
Without soft costs coverage, the developer must pay this entire amount out of pocket, in addition to any deductible or coinsurance on the physical damage claim. With a soft costs endorsement providing $500,000 of coverage (10% of $5 million completed value), all these expenses are covered, subject to the policy deductible.
Builders’ Risk Insurance Cost Factors
Builders’ risk insurance premiums typically range from 1% to 5% of the total construction project value. This wide range reflects the many variables that insurers consider when pricing coverage. Understanding these factors helps you estimate costs and potentially reduce premiums.
Primary Cost Drivers
Project Value: The single largest factor affecting premium cost. A $100,000 renovation might cost $1,000 to $5,000 to insure, while a $1 million project costs $10,000 to $50,000. Premiums increase proportionally with project value because higher values create larger potential losses for insurers.
Project Location: Properties in areas with higher crime rates, greater wildfire risk, hurricane exposure, or earthquake potential cost more to insure. Coastal properties in Florida or California face higher premiums than similar projects in the Midwest. Zip code-level data drives much of this pricing variation.
Construction Type: Wood frame construction costs more to insure than masonry or concrete construction because wood is more vulnerable to fire. The construction type of both the existing structure and the renovation work affects pricing. Mixed construction projects with both wood and masonry elements may fall into higher rating categories.
Project Duration: Longer project timelines increase exposure time and therefore increase premiums. A 6-month renovation policy costs less than a 12-month policy for the same project value. If your project experiences delays requiring policy extensions, expect to pay additional premiums for the extended period.
Existing Structure Inclusion: Renovations that include coverage for existing structures cost more than policies covering only new work. The existing structure value, age, and condition all affect pricing. Older existing structures with greater depreciation may cost less to insure because the actual cash value is lower.
Deductible Selection: Higher deductibles reduce premiums. Standard deductibles range from $1,000 to $10,000. Increasing your deductible from $2,500 to $5,000 might reduce premiums by 15% to 25%. Large projects may have deductibles of $25,000 or more to manage premium costs.
Contractor Experience: Projects performed by experienced, licensed contractors with good safety records and no recent claims may qualify for better pricing. Some insurers offer credits for contractors who have been in business for many years or who belong to industry associations.
Loss Control Measures: Properties with security systems, fire alarms, sprinkler systems, or other protective devices may receive premium discounts. Regular security patrols, good lighting, and fencing around the construction site demonstrate risk management that insurers reward with lower premiums.
Additional Coverage and Endorsements
Basic builders’ risk coverage represents the starting point for premium calculations. Additional coverages and endorsements increase premiums proportionally to the additional risk they cover:
- Soft Costs Endorsement: Adds 10% to 25% to the base premium
- Flood Coverage: Adds 5% to 50% depending on flood zone designation
- Earthquake Coverage: Adds 2% to 20% based on seismic zone and construction type
- Ordinance or Law Coverage: Adds 5% to 15% to cover additional costs of complying with updated building codes
- Pollutant Cleanup and Removal: Adds 5% to 10% to cover environmental remediation costs
- Expediting Expenses: Adds 3% to 8% to cover costs of expedited shipping and overtime labor
Common Mistakes to Avoid
Assuming Your Contractor’s Insurance Is Sufficient
Many property owners mistakenly believe that their general contractor’s insurance provides adequate protection for their renovation project. Contractors typically carry general liability insurance and workers’ compensation insurance. General liability insurance covers bodily injury to third parties and damage to property other than the work the contractor is performing.
General liability policies specifically exclude property damage to “your work” and “your product.” This exclusion means the contractor’s general liability policy does not cover damage to your home or the renovation work itself. If a fire, theft, or vandalism damages your project, the contractor’s general liability policy will deny the claim.
Some contractors carry their own builders’ risk insurance, but these policies protect the contractor’s interests, not yours. The policy limits may be inadequate for your project value. The contractor controls the claims process and insurance proceeds, potentially creating conflicts if the contractor has financial problems. Always verify coverage independently rather than assuming your contractor has adequate insurance.
Underinsuring the Project Value
Property owners often undervalue their projects to save on insurance premiums. They may calculate only the value of materials and exclude labor costs. They may insure only the current construction phase rather than the completed value. These mistakes create coinsurance penalties that drastically reduce claim payments.
Most builders’ risk policies include an 80% coinsurance clause. This provision requires you to insure the project for at least 80% of its completed value. If you fail to meet this requirement, the insurer reduces claim payments by the percentage you are underinsured, even for partial losses.
Example: Your project has a completed value of $500,000. You purchase a policy with a $300,000 limit (60% of completed value, below the 80% requirement). A fire causes $100,000 in damage. The coinsurance penalty calculation is:
($300,000 actual coverage ÷ $400,000 required coverage) × $100,000 loss = $75,000 payment
You receive only $75,000 of the $100,000 loss, paying $25,000 out of pocket due to underinsurance, plus your deductible.
Failing to Extend Coverage for Project Delays
Construction projects frequently experience delays due to weather, material shortages, labor issues, or permitting problems. When your project extends beyond the original policy period, you must request a policy extension before the original policy expires. If you allow the policy to expire, you must apply for new coverage and may face higher rates or coverage restrictions.
Set calendar reminders 30 days before your policy expiration date. Contact your insurance agent immediately if you anticipate project delays. Most insurers charge additional premiums for extensions based on the extended time period and remaining project value. These extension premiums are far less costly than having no coverage.
Not Documenting Materials and Work Progress
In the event of a claim, you must prove what materials were on site, what work had been completed, and the value of damaged property. Many property owners fail to maintain adequate documentation, leading to disputes with insurers and reduced claim settlements.
Take dated photographs of the project weekly, showing materials deliveries, work progress, and completed work. Keep all receipts for materials purchases, showing quantities, descriptions, and values. Maintain a project log documenting contractor work schedules, subcontractor activities, and major project milestones. Create a material inventory listing items delivered but not yet installed.
This documentation serves multiple purposes beyond insurance claims. It helps you verify contractor billing, monitor project progress, and defend against contractor liens. The minimal time investment in maintaining project records can prevent tens of thousands of dollars in claim disputes.
Choosing the Cheapest Policy Without Reviewing Coverage
Builders’ risk policies from different insurers can have vastly different coverage provisions, exclusions, and limitations. The lowest-premium policy may exclude critical coverages or have restrictive claim settlement provisions. Always compare policies based on coverage quality, not just price.
Review the definition of “covered property” carefully. Some policies exclude certain types of materials or limit coverage for materials stored off-site. Check whether the policy covers materials in transit from suppliers to your jobsite. Verify that the policy covers tools and equipment if this protection is important to your project.
Examine the covered perils section. “All-risk” policies provide broader coverage than “named peril” policies. Confirm that the policy covers theft, vandalism, and water damage, which represent common causes of loss during renovation projects. Review exclusions carefully to understand what risks are not covered.
Not Coordinating Coverage Transition to Permanent Insurance
When your renovation project completes, your builders’ risk policy terminates. You must have permanent property insurance in place immediately when the project finishes and you reoccupy the property. Gaps between the builders’ risk policy termination and permanent insurance activation leave you uninsured.
Contact your homeowners insurance agent 30 days before anticipated project completion. Provide updated information about the renovated property, including increased square footage, upgraded systems, and higher reconstruction cost. Your dwelling coverage limit will need to increase to reflect the home’s enhanced value.
Some insurers offer automatic conversion from builders’ risk to permanent property insurance at project completion. This feature eliminates coverage gaps and simplifies the transition process. If your insurer offers this option, consider the convenience benefit even if premiums are slightly higher.
Ignoring Local Ordinance or Law Coverage
When damage occurs to your property during renovation, local building codes may require you to upgrade the entire structure to current standards, not just repair the damaged portion. Building codes change frequently, particularly electrical, plumbing, and structural requirements. The cost to bring an older home up to current code can be substantial.
Standard builders’ risk policies exclude the increased cost to comply with building ordinances or laws. You must purchase ordinance or law coverage by endorsement. This coverage typically adds 10% to 25% to your policy limit to cover the increased cost of code compliance.
Without ordinance or law coverage, you pay the entire code upgrade cost out of pocket. For older homes, these costs can easily reach $50,000 to $100,000 or more. The relatively modest endorsement premium provides protection against this significant exposure.
Do’s and Don’ts for Renovation Insurance
Do’s: Seven Critical Actions
1. Do purchase builders’ risk coverage before materials arrive at the jobsite. Coverage should begin before the first materials delivery, not when construction starts. Many claims occur during the initial project phases when expensive materials are vulnerable to theft. Coverage must be in place by the time materials reach your property to ensure protection from the moment value exists at risk.
2. Do calculate and separately specify values for existing structure and renovation work. Never combine these values or use your home’s market value. Use replacement cost valuation tools to determine the existing structure’s value, then adjust for depreciation to establish actual cash value. Calculate the renovation’s completed value including all materials, labor, overhead, and profit to determine proper coverage limits.
3. Do add a soft costs endorsement for projects exceeding $500,000 or lasting longer than six months. Soft costs coverage protects you from the substantial additional expenses that accumulate when covered losses delay your project. The relatively modest endorsement cost (typically adding 10% to 25% to base premiums) provides protection worth up to 10% of your project value.
4. Do name your lender as loss payee and certificate holder if your project involves financing. Lenders require this designation to protect their collateral interest in the property. Failure to properly name your lender as loss payee can result in loan default, even if you maintain adequate coverage. Provide your lender with a certificate of insurance showing their interest is properly noted.
5. Do maintain detailed photographic documentation of work progress and materials on site weekly. Use your smartphone to take dated photos from multiple angles showing the state of construction and any materials delivered. Create a simple file system organizing photos by date and project phase. This documentation becomes invaluable if you must file a claim and prove the value of work completed or materials lost.
6. Do notify your insurance agent immediately if project delays will extend beyond your policy expiration date. Request extensions before your coverage lapses, not after. Insurers charge additional premiums for extensions, but these costs are far less than having no coverage. Set calendar alerts 30 days before policy expiration to ensure you address extensions proactively.
7. Do review contractor and subcontractor insurance certificates to verify adequate liability coverage. While builders’ risk covers property damage to your project, you need contractors with proper liability coverage to protect against injury claims and damage to neighboring properties. Require certificates of insurance showing minimum limits of $1 million general liability and statutory workers’ compensation coverage. Verify the certificate lists your property address as the location of covered operations.
Don’ts: Seven Costly Mistakes to Avoid
1. Don’t rely on your homeowners insurance policy alone for renovations exceeding 10% of your dwelling coverage limit. Homeowners policies contain specific renovation exclusions and limitations that create coverage gaps during construction. The special construction deductible (5% of dwelling limit) and actual cash value settlement for major renovations make homeowners policies inadequate for significant projects.
2. Don’t use your home’s market value or purchase price to calculate insurance coverage limits. Market value includes land value and reflects market conditions unrelated to reconstruction cost. Builders’ risk policies cover construction cost, not market value. Using market value typically results in overinsuring (wasting premium dollars) or underinsuring if your home’s market value is depressed below reconstruction cost.
3. Don’t allow your builders’ risk policy to lapse before project completion and certificate of occupancy issuance. The period immediately before completion remains vulnerable to losses. Many claims occur during final project phases when substantial value exists but protective systems may not yet be operational. Coverage must continue until you receive the certificate of occupancy and permanent property insurance takes effect.
4. Don’t assume coverage includes flood or earthquake protection without verifying and adding these endorsements. Standard builders’ risk policies exclude flood damage and earthquake damage. If your project location faces these risks, you must purchase separate endorsements. Flood coverage availability depends on your property’s flood zone designation. Earthquake coverage cost depends on your seismic zone and construction type.
5. Don’t fail to notify your homeowners insurer about your renovation project before work begins. Even if you purchase separate builders’ risk coverage, notify your homeowners carrier. Some homeowners policies require notification of renovations as a condition of continuing coverage. Failure to notify can result in claim denials for losses to parts of your property not covered by the builders’ risk policy.
6. Don’t choose “excluding existing structure” coverage without confirming your homeowners policy will cover the existing building during renovation. This decision creates a coverage gap where no policy responds to damage affecting existing portions of your home. Get written confirmation from your homeowners insurer specifying that they will continue to provide coverage despite the renovation work. Document this confirmation with email or letters from your insurer.
7. Don’t ignore protective safeguards requirements specified in your builders’ risk policy. Many policies require certain protective measures such as fire extinguishers, locked gates, security systems, or regular monitoring. These requirements are policy conditions that, if violated, can reduce or eliminate coverage. Review the protective safeguards section of your policy and implement required measures before coverage begins.
Pros and Cons of Purchasing Builders’ Risk Insurance for Renovations
Pros: Seven Key Benefits
1. Eliminates the special construction deductible that homeowners policies impose on major renovations. This benefit alone can save $25,000 to $50,000 on a claim. Homeowners policies apply deductibles equal to 5% of dwelling coverage for renovation-related losses, while builders’ risk policies maintain standard deductibles of $1,000 to $5,000. This deductible difference makes builders’ risk coverage cost-effective even for relatively modest claims.
2. Provides replacement cost settlement for renovation work rather than depreciated actual cash value. Replacement cost coverage pays to repair or replace damaged property using new materials at current prices without deducting depreciation. Actual cash value settlement reduces payments by 20% to 50% or more based on the age and condition of damaged property. This valuation difference can represent $50,000 to $200,000 on major renovation projects.
3. Covers materials and fixtures from the time they leave the supplier until permanent installation. This protection is critical because expensive materials face significant theft and damage risks during the vulnerable period between delivery and installation. High-end appliances, custom cabinets, and luxury fixtures can represent $50,000 to $150,000 in value. Homeowners policies provide little or no coverage for these materials before they become a permanent part of the building.
4. Avoids vacancy clause exclusions that eliminate coverage under homeowners policies. Builders’ risk policies have no vacancy restrictions because they are designed specifically for properties under construction. This feature provides crucial protection for renovations requiring you to vacate your home. Without builders’ risk coverage, the 60-day vacancy clause eliminates coverage for vandalism, theft, water damage, and glass breakage.
5. Satisfies lender requirements for construction loans and refinancing with renovation proceeds. Construction lenders will not close loans without proof of adequate builders’ risk coverage naming the lender as loss payee. This insurance represents a loan condition that you must satisfy to access financing. The coverage protects both your equity and the lender’s collateral interest in the property.
6. Offers soft costs coverage for financial losses resulting from construction delays caused by covered losses. Soft costs endorsements typically provide coverage equal to 10% of your project value, potentially $50,000 to $200,000 on large renovations. This coverage reimburses additional loan interest, permit fees, professional fees, and other expenses that accumulate during extended construction periods. Without this protection, these costs come entirely from your own funds.
7. Provides peace of mind knowing that your substantial investment has comprehensive protection during the risky construction period. Renovation projects represent major financial commitments often financed through home equity, refinancing, or loans. Knowing that builders’ risk coverage protects this investment allows you to focus on project management rather than worrying about catastrophic uninsured losses. The coverage cost of 1% to 5% of project value is modest compared to the financial protection provided.
Cons: Five Limitations to Consider
1. Represents an additional cost of 1% to 5% of total project value that increases overall renovation expenses. For a $200,000 renovation, builders’ risk insurance costs $2,000 to $10,000. This expense must be factored into your overall project budget. Some homeowners who underestimate total project costs may find the insurance premium strains their budget. However, the cost of insurance must be weighed against the risk of total uninsured loss potentially exceeding the entire project value.
2. Requires careful coordination between builders’ risk coverage and permanent property insurance to avoid gaps. You must manage the transition from temporary builders’ risk coverage to permanent homeowners or commercial property insurance at project completion. This transition requires communication with your insurance agent 30 days before anticipated completion. Coverage gaps during transitions leave you temporarily uninsured despite paying for two separate policies.
3. Existing structure coverage typically provides only actual cash value settlement rather than replacement cost. While builders’ risk policies provide replacement cost for renovation work, most insurers offer only ACV coverage for existing structures being renovated. The depreciation deduction on older portions of your home can result in claim payments substantially below the actual cost to repair or replace damaged property. This limitation catches many property owners by surprise when they file claims.
4. May include substantial exclusions for faulty workmanship, design defects, and gradual deterioration. Standard builders’ risk policies exclude costs to repair defective materials or poor workmanship. These exclusions can be partially addressed through LEG-3 endorsements, but such endorsements typically add 10% to 20% to premium costs. Property owners must understand that builders’ risk insurance protects against fortuitous losses like fire and theft, not against construction defects or quality issues.
5. Requires ongoing premium payments for policy extensions if your project experiences delays. Construction projects often exceed original timelines due to permit delays, weather, material shortages, or contractor scheduling problems. Each delay requiring policy extension generates additional premium charges. For projects that run six months over schedule, extension premiums can add $3,000 to $15,000 to your insurance costs. These additional premiums represent unforeseen expenses that strain renovation budgets.
Understanding Policy Exclusions and Limitations
Every builders’ risk policy contains exclusions that deny coverage for certain types of losses or circumstances. Understanding these exclusions is critical to avoiding claim surprises and knowing when you need additional coverage.
Standard Exclusions
Faulty Workmanship and Design: Policies exclude costs to repair or replace work that was performed incorrectly or designed improperly. If your contractor installs defective concrete or your architect specifies inadequate structural support, the policy will not pay to redo this work. However, if the defective work causes damage to other parts of the project, an ensuing loss clause or LEG-3 endorsement may provide coverage for the resulting damage.
Wear and Tear, Deterioration, and Inherent Vice: Normal wear, gradual deterioration, rust, mold, and similar conditions are excluded. Builders’ risk policies cover sudden and accidental losses, not gradual processes. If your project stalls for months and materials deteriorate due to weather exposure, this damage is not covered.
Earth Movement: Earthquakes, landslides, sinkholes, and settling are excluded under standard policies. You must purchase earthquake coverage by endorsement if your project location faces seismic risk. The endorsement typically adds 2% to 20% to premiums depending on your seismic zone and construction type.
Flood and Surface Water: Flood damage is excluded and must be covered through separate flood insurance. National Flood Insurance Program (NFIP) policies do not cover buildings under construction unless the building has been previously occupied. Private flood insurance may provide builders’ risk-type coverage for construction projects in flood zones.
Theft of Materials Without Forced Entry: Many policies require evidence of forced entry to trigger theft coverage. Materials that simply disappear from an unsecured construction site may not be covered. This exclusion particularly affects projects where the site remains largely open and accessible.
LEG Defect Clauses
The London Engineering Group developed a series of clauses addressing coverage for defects, known as LEG-1, LEG-2, and LEG-3. These clauses modify the standard faulty workmanship exclusion:
LEG-1 provides the most restrictive coverage, completely excluding loss or damage due to defects of material, workmanship, design, plan, or specification. This clause offers no coverage for damages resulting from defective work.
LEG-2 represents a compromise approach. It excludes the cost to rectify defects but covers damage to other parts of the project caused by the defect. Under LEG-2, if defective plumbing causes water damage to completed work, the policy would not pay to replace the defective plumbing but would cover the water-damaged finished work.
LEG-3 provides the broadest coverage by limiting exclusions to costs incurred to improve or upgrade the original materials, workmanship, design, plan, or specification. Recent court decisions have interpreted LEG-3 favorably for policyholders, finding that it provides coverage for replacing defective work with work meeting the original specifications, as long as the replacement does not involve an improvement or upgrade.
Real-World Claim Examples
Example 1: Fire Destroys 80% Complete Renovation
A property owner hired a contractor to perform a $600,000 renovation on a two-year-old vacant single-family home. The agent secured a builders’ risk policy but selected the “excluding existing structure” option to save on premiums. The policy limit was set at $600,000.
When the renovation reached 80% completion, an electrical fire broke out, causing extensive damage. The claims adjuster determined that most of the damage affected the existing structure, while only a portion affected the new renovation work.
The homeowner expected the $600,000 policy to cover all damage, assuming the amount represented $200,000 for renovations and $400,000 for the existing structure. However, because the agent selected coverage excluding the existing structure, the policy’s declarations page showed $0 coverage for the existing building and $600,000 for renovations only.
The insurer denied the entire $400,000 claim for existing structure damage and paid only for the damaged renovation work, calculated at 80% of $200,000, or $160,000. The property owner suffered a $440,000 uninsured loss ($400,000 existing structure + $40,000 uncompleted renovation work).
This example illustrates the critical importance of clearly understanding and properly selecting coverage for existing structures when purchasing builders’ risk insurance for renovation projects.
Example 2: Hurricane Damage to Incomplete New Construction
A homeowner purchased a builders’ risk policy for a $400,000 new home construction project. The policy inception date was set for the date the agent issued the policy. However, when the agent wrote the policy, the contractor had already completed 35% of the work, with $140,000 in value already in place.
Three weeks after the policy inception date, a hurricane struck, causing $125,000 in damage to the partially completed home. The flooring had been installed, trim work had started, and cabinets were present but not yet installed.
The insurance adjuster noted that the policy contained an exclusion for structures more than 30% complete unless underwriting approval was granted before coverage began. No such approval existed because the agent had not disclosed the 35% completion status when applying for coverage.
The insurer settled only for work performed from the policy’s effective date to the hurricane date—approximately two weeks of work valued at $15,000. The remaining $110,000 of damage to work completed before the policy inception date was denied under the 30% completion exclusion.
This example demonstrates the importance of purchasing builders’ risk coverage before construction begins, accurately disclosing project status during the application process, and obtaining underwriting approval if coverage begins after work has already progressed.
Example 3: Contractor Theft and Vandalism
A homeowner undertook a $200,000 renovation of a 26-year-old single-family beach home. The property remained unoccupied during the six-month construction period. The homeowner relied on his existing homeowners policy for protection and did not purchase separate builders’ risk coverage.
After three months of work, a passerby threw a Molotov cocktail at the structure, causing minor fire damage and extensive smoke damage totaling $45,000. The homeowner filed a claim under his homeowners policy.
The insurer denied the claim, citing the vacancy clause in the homeowners policy. The property had been vacant for more than 60 days, and the policy specifically excluded vandalism and malicious mischief losses to dwellings vacant for more than 60 consecutive days.
The homeowner argued that the property was “under renovation” and therefore should not be considered vacant under the exception in the policy language. The insurer investigated and found that while the contractor had been working on the property, work had been intermittent, with several multi-week periods where no one was present at the site.
Because the homeowner could not document substantial, continuous renovation activity during the entire 60-day period preceding the loss, the insurer maintained its denial. The homeowner ultimately paid the entire $45,000 loss personally, plus experienced a multi-month delay in the project while negotiating with the insurer and completing repairs.
This example highlights the danger of relying on homeowners insurance during extended renovations and the importance of purchasing dedicated builders’ risk coverage that does not contain vacancy restrictions.
Frequently Asked Questions
Does homeowners insurance cover renovation damage?
No. Most homeowners policies exclude or severely limit coverage during major renovations exceeding 10% of dwelling value. Special construction deductibles and vacancy clauses create substantial gaps requiring separate builders’ risk insurance.
Is builders’ risk insurance legally required?
No federal law requires it, but construction lenders mandate coverage as a loan condition. Many municipalities require proof of coverage before issuing building permits. Construction contracts typically require one party to purchase the policy.
How much does builders’ risk insurance cost?
Between 1% and 5% of total project cost. A $200,000 renovation typically costs $2,000 to $10,000 to insure, based on location, construction type, duration, and coverage options selected.
Can I cancel builders’ risk insurance after purchase?
Yes, but cancellation requires written notice to the insurer. Refunds for unearned premium follow short-rate tables that reduce refunds below pro-rata amounts. Canceling before project completion creates dangerous uninsured exposure.
Does builders’ risk insurance cover contractor mistakes?
No, standard policies exclude faulty workmanship. LEG-3 endorsements provide limited coverage for damage caused by defects but exclude costs to improve or upgrade defective work to better-than-original specifications.
When should I buy builders’ risk insurance?
Before materials arrive at the jobsite. Coverage should begin before the first delivery, not when construction starts. Many valuable materials face theft risk immediately upon delivery before installation.
Who should purchase the builders’ risk policy?
Property owners should purchase policies themselves rather than relying on contractor-procured coverage. Owner-controlled policies ensure adequate limits, proper endorsements, and that insurance proceeds rebuild the property rather than potentially paying contractor debts.
Does builders’ risk insurance cover landscaping and fences?
Limited coverage typically applies to fences, retaining walls, and temporary structures. Landscaping including trees, shrubs, and lawns generally has limited coverage or requires specific endorsement. Standard policies focus on buildings and structures.
What happens if my project runs over schedule?
Request a policy extension before your original policy expires. Insurers charge additional premiums for extensions based on the extended period and remaining project value. Allowing coverage to lapse requires applying for new coverage at potentially higher rates.
Is theft covered under builders’ risk insurance?
Yes, with limitations. Many policies require evidence of forced entry to trigger theft coverage. Materials simply disappearing from unsecured sites may be excluded. Theft coverage for tools and equipment often requires specific endorsement.
Does builders’ risk insurance cover my personal belongings?
No, builders’ risk policies cover only buildings, structures, materials, and fixtures related to the construction project. Personal property such as furniture, clothing, and electronics requires separate coverage under homeowners or tenant policies.
Can I get builders’ risk insurance if construction already started?
Possibly, but insurers may require inspection and will exclude pre-existing damage. Projects more than 30% complete typically need underwriting approval. Starting construction before securing coverage creates substantial risk of uninsured loss.
What is “completed value” versus “current value”?
Completed value represents what the project will be worth when finished, including all materials, labor, and profit. Current value reflects only work done to date. Policies should be written for completed value to avoid coinsurance penalties.
Does builders’ risk insurance cover code upgrades?
No, without an ordinance or law endorsement. Standard policies cover restoring property to its pre-loss condition. Code upgrades required by current building codes need separate coverage typically adding 10% to 25% to policy limits.
What is the difference between replacement cost and actual cash value?
Replacement cost pays to rebuild using new materials at current prices without depreciation. Actual cash value deducts depreciation based on age and condition, resulting in payments 20% to 50% lower than replacement cost.
How long does builders’ risk coverage last?
Project-specific terms of 3, 6, 9, or 12 months are standard. Coverage ends at the earliest of project completion, property occupation, certificate of occupancy issuance, or policy expiration date, whichever occurs first.
Is mold damage covered under builders’ risk insurance?
Limited coverage applies only when mold results from a covered peril like a burst pipe. Mold from lack of proper drying, construction defects, or long-term moisture is excluded. Prevention is essential since coverage is restricted.
Does builders’ risk insurance cover damage during occupancy?
No once you reoccupy the property, builders’ risk coverage terminates. You need permanent homeowners or commercial property insurance before moving back in. Partial occupancy may also terminate coverage depending on policy language.
