Yes, builders’ risk insurance does cover equipment—but with important limits and conditions. The coverage applies specifically to equipment that becomes a permanent part of the building structure or is temporarily used on the job site to support construction. However, major contractor equipment like bulldozers and excavators typically requires separate insurance coverage.
According to a 2024 analysis on construction insurance, approximately 73% of construction projects experience some form of equipment-related loss or damage during the building phase. This statistic underscores why understanding the exact boundaries of your coverage matters—the difference between what is and isn’t covered can mean thousands of dollars in out-of-pocket losses.

Understanding Builders’ Risk Equipment Coverage: Core Concepts
Builders’ risk insurance operates fundamentally differently from general commercial property coverage. According to Insurance Services Office guidance, builders’ risk focuses on protecting the project itself—the structure under construction and the materials becoming part of it—rather than protecting a contractor’s tools and equipment used to perform the work.
This distinction creates the first critical dividing line in equipment coverage. Equipment falls into two categories: (1) equipment being installed as part of the building and (2) equipment used to build the project. Understanding which category your equipment falls into determines whether builders’ risk covers it or whether you need separate contractors’ equipment insurance.
Equipment Intended to Become a Permanent Part of the Building
When equipment or systems are destined to become part of the finished structure, builders’ risk covers them during the construction phase. This includes HVAC systems, electrical panels, elevators, plumbing fixtures, and appliances awaiting installation. A comprehensive guide on installation floaters explains that these materials are protected from the moment they arrive on-site until they’re permanently installed and the project is completed.
The coverage protects against damage from fire, theft, vandalism, and weather-related incidents. If an HVAC unit worth $8,000 is stolen from a job site before installation, or if wind damage destroys electrical panels stored temporarily on the property, builders’ risk would typically reimburse these losses. The key requirement is that the damaged property must be destined to become a permanent part of the structure.
Equipment Used to Build the Project (Not Becoming Part of It)
Contractors’ equipment—machinery and tools used to perform the work rather than to become part of the building—falls outside standard builders’ risk coverage in most situations. The Hartford’s comprehensive exclusions guide notes that major equipment like bulldozers, excavators, cranes, and ditch diggers are specifically excluded from typical builders’ risk policies.
This exclusion exists because contractors’ equipment insurance is designed to protect this category of property. A bulldozer worth $150,000 damaged during excavation work, a rented crane that breaks down on-site, or power tools stolen from a locked container would not be covered under builders’ risk. Instead, these require contractors’ equipment insurance, also called inland marine coverage specifically designed for mobile machinery.
Core Components of Equipment Coverage Under Builders’ Risk
What Builders’ Risk Covers Regarding Equipment
According to Bankrate’s analysis of builders’ risk coverage, equipment coverage under builders’ risk includes:
Materials and fixtures destined for installation – Roofing materials, windows, flooring, plumbing fixtures, light fixtures, cabinetry, and HVAC components all receive protection while on-site, in temporary storage, or in transit to the job site.
Building systems during installation – Electrical systems, plumbing systems, HVAC equipment, and security systems being installed as permanent components are covered against damage from covered perils.
Temporary structures and site equipment – Scaffolding, temporary fencing, construction trailers, and site amenities used during construction often receive coverage, though this varies by policy. Policy reviews should verify whether scaffolding and temporary buildings are included or need separate endorsement.
Coverage extends across three locations: on-site at the construction location, in transit from suppliers to the job site, and at temporary storage locations off-site, provided the policy specifically permits off-site storage coverage.
How Coverage Functions: The “Becoming Part of Building” Principle
The controlling principle determining whether equipment receives builders’ risk protection is straightforward: will this equipment become a permanent part of the finished structure? If yes, it’s covered. If no, it requires separate insurance.
The Post Insurance explanation of builders’ risk scope clarifies that policies should include “all fixtures, materials, machinery, and equipment that constitute a permanent part of the structure.” This language appears in most policy documents because it directly determines coverage applicability.
A concrete example illustrates this principle: A commercial construction project requires an industrial-grade HVAC system costing $35,000. Once installed, this system becomes a permanent part of the building—it stays with the property when construction completes. Therefore, builders’ risk covers this equipment during transit, temporary storage, and installation. Conversely, the construction company’s own air compressor used to power tools is temporary equipment used to build the system. When that compressor finishes its job, it leaves the site with the contractor. Builders’ risk excludes this equipment; it needs contractors’ equipment insurance instead.
Timing Matters: When Coverage Begins and Ends
According to Procore’s guide on builders’ risk timing, equipment coverage for materials becoming part of the building typically begins when the property owner takes possession of the equipment and begins transport to the job site. This “point of possession” trigger is critical because it means an expensive fixture damaged in transit to the site—before it ever arrives at the construction location—may still be covered.
Coverage continues through temporary storage on-site, waiting for installation, and throughout the installation process. The coverage period ends once the equipment is permanently installed and the building project is considered substantially complete. Installation floater guides explain that coverage remains active during installation, protecting the property “until the work is completed and accepted.”
Distinguishing Equipment Coverage: Builders’ Risk vs. Installation Floaters vs. Contractors’ Equipment
The construction insurance landscape contains three distinct but sometimes overlapping policies. Understanding which policy covers which equipment prevents the dangerous situation where you assume coverage exists under one policy, only to discover at claim time that it’s excluded.
| Coverage Type | Primary Purpose | Who Typically Buys It | When Equipment is Protected |
|---|---|---|---|
| Builders’ Risk | Entire construction project, structure, and materials becoming permanent | Property owners, general contractors | On-site, in transit to site, temporary storage before installation |
| Installation Floater | Specific contractor’s materials from purchase through installation | Subcontractors, specialty trades | Purchase, in-transit, storage, and installation phase |
| Contractors’ Equipment | Contractor’s tools, machinery, and equipment used to perform work | Contractors, construction companies | Owned or rented equipment used at job sites |
Installation Floaters: The Specialized Coverage Gap-Filler
Many subcontractors and specialty trades face a coverage gap with standard builders’ risk policies. The PIA Insurance guide on installation floaters notes that while builders’ risk provides broad project coverage, it may leave gaps for specialized installations or equipment with tight control requirements.
An installation floater specifically protects materials under a particular contractor’s control—from purchase through installation completion. A plumbing subcontractor purchasing high-end fixtures, an HVAC specialist ordering custom ductwork, or an electrical contractor procuring specialized panels can use installation floaters to ensure coverage from their warehouse through the job site and into final installation.
The timing advantage proves crucial. Builders’ risk may provide coverage only once materials arrive at the job site. An installation floater, by contrast, covers materials during the supplier-to-contractor transit phase, often days or weeks before job-site arrival. If expensive custom cabinets are stolen while temporarily stored at the subcontractor’s facility before being transported to the construction site, an installation floater covers this loss, while a standard builders’ risk policy would not.
Scenario illustrating the difference: A tile contractor orders $15,000 worth of custom marble tiles for a commercial renovation. The tiles are shipped from overseas, arrive at the contractor’s warehouse, are stored for three weeks waiting for the project to reach the tiling phase, then are transported to the job site. During warehouse storage, water damage ruins 40% of the tiles.
- Builders’ risk (property owner’s policy): Would not cover damage to materials not yet at the construction site.
- Installation floater (tile contractor’s policy): Would cover warehouse damage because the contractor controlled the materials during that storage period.
Contractors’ Equipment Insurance: Coverage for Tools and Machinery
According to the AAIS analysis of contractors’ equipment coverage, contractors’ equipment insurance protects owned or rented machinery used in construction—equipment that does not become part of the building. This includes bulldozers, excavators, generators, air compressors, concrete pumps, and similar heavy machinery.
The fundamental principle is that builders’ risk policies explicitly exclude equipment not intended to be made part of the building. A general contractor cannot file a claim under the project’s builders’ risk policy for a rented crane that breaks down, a stolen generator, or a bulldozer damaged through collision with another vehicle. These losses require separate contractors’ equipment coverage.
Three Common Real-World Scenarios: Actions and Consequences
Scenario 1: Residential Home Renovation with Purchased Equipment
Context: A homeowner contracts with a general contractor for a complete kitchen renovation including new cabinets, countertops, and appliances costing $42,000 total. The project includes new electrical wiring, plumbing upgrades, and an HVAC system serving the renovated space.
| Action | Coverage Consequence |
|---|---|
| Contractor obtains builders’ risk policy covering the $42,000 renovation value, naming homeowner as additional insured | All purchased equipment destined for permanent installation—cabinets, appliances, electrical components, plumbing fixtures, HVAC equipment—is protected under the policy. |
| Cabinets arrive at contractor’s workshop and are stored for 10 days before transport to homeowner’s house | Not covered under standard builders’ risk unless policy specifically includes off-site storage at contractor locations. If cabinets are damaged or stolen during this storage period, the loss falls on the contractor. |
| Cabinets are transported to the job site; a traffic accident damages $8,000 worth of cabinetry while en route | Covered under builders’ risk because the equipment is in-transit to the construction location, and most policies extend to materials in transit. The homeowner’s policy reimburses the cabinet supplier for replacement materials. |
| New $6,500 HVAC system is damaged by water intrusion while temporarily stored on-site, waiting for installation crew | Covered under builders’ risk. The equipment is destined to become a permanent building component and is stored on the construction site. The insurer reimburses for system replacement or repair. |
| Contractor’s power tools (drills, saws, circular saw, nail guns) worth $3,500 are stolen from a locked tool box on-site | Not covered under builders’ risk. These are contractor-owned tools used to perform the work, not equipment becoming part of the building. The contractor should carry inland marine coverage for tools and equipment. |
| Project experiences a fire that damages both the installed framing and new electrical panel awaiting connection | Covered under builders’ risk. Both the structural damage and the equipment damage result from a covered peril (fire). |
Key Takeaway: The homeowner’s builders’ risk policy protects purchased equipment destined for permanent installation but does nothing to protect the contractor’s own working equipment. Disputes often arise when contractors assume their tools are covered, only to file claims that get denied.
Scenario 2: Commercial Construction with Rented Equipment
Context: A commercial construction company builds a five-story office building. The general contractor secures builders’ risk coverage for the $18 million project. The contractor also rents heavy equipment—a mobile crane worth $250,000 monthly rental value, concrete pumping equipment, and a diesel generator.
| Action | Coverage Consequence |
|---|---|
| Builders’ risk policy is obtained for the $18 million building value; rented equipment is not listed on the policy | The project structure, permanent building systems, installed fixtures, and purchased materials are protected. The rented equipment is not. |
| The rented diesel generator fails mechanically mid-project due to internal engine damage unrelated to external events | Not covered under builders’ risk. According to insurance experts, equipment breakdown from mechanical or electrical failure is specifically excluded from builders’ risk policies because breakdowns result from internal failures rather than external perils. The contractor is responsible for equipment breakdown insurance or bears the repair/replacement cost. |
| A power surge from a lightning strike damages the generator’s electrical control panel (external peril, not mechanical failure) | Covered under builders’ risk if the generator damage results from a covered external peril like lightning. The policy reimburses for the repair. |
| The rented mobile crane tips over due to operator error while lifting steel beams, causing $80,000 damage to the crane | Not covered under builders’ risk. The crane is temporary equipment used to build the structure, not permanent equipment becoming part of it. The contractor should carry contractors’ equipment insurance covering rented equipment. The rental company may have coverage under their equipment insurance, but the contractor bears responsibility for the damage. |
| Permanent structural steel beams worth $400,000 are delivered and stored on-site for two weeks before installation; vandals damage $60,000 worth | Covered under builders’ risk. The steel is destined to become a permanent building component and is damaged by a covered peril (vandalism). The insurer reimburses for replacement or repair. |
| During installation of the new HVAC system destined to serve the building, equipment is damaged by falling debris from the structure above | Covered under builders’ risk. The HVAC system is equipment becoming a permanent part of the building. Damage from a construction accident involving falling debris triggers coverage. |
Key Takeaway: Rented heavy equipment used to build the project requires separate contractors’ equipment insurance. Builders’ risk covers only equipment becoming permanent building components. A contractor who relies solely on builders’ risk for a project with significant rented equipment faces substantial uninsured exposure.
Scenario 3: Specialty Contractor Installation Without General Contractor’s Builders’ Risk
Context: A mechanical contractor subcontracts to install $120,000 of specialized HVAC equipment in a new office building. The general contractor has obtained builders’ risk coverage for the overall project. The mechanical contractor fabricates custom ductwork at their facility and later installs it on-site.
| Action | Coverage Consequence |
|---|---|
| The general contractor’s builders’ risk policy covers “all equipment and materials on the project site” but has a $15,000 deductible per claim | The mechanical contractor’s ductwork should be covered by the general contractor’s builders’ risk once it arrives at the job site and before installation. However, the high deductible means small losses fall on the mechanical contractor. |
| Custom ductwork is fabricated at the mechanical contractor’s facility, then stored for two weeks before transport to the job site; fire damages $40,000 worth | Not covered under the general contractor’s builders’ risk. The equipment is not yet at the project site; it’s at the mechanical contractor’s facility. The mechanical contractor should carry an installation floater protecting their materials from fabrication through final installation. Without this coverage, the $40,000 loss is uninsured. |
| During transport to the project site, weather damage occurs to $25,000 worth of ductwork; the mechanical contractor files a claim under the general contractor’s builders’ risk | Likely not covered. Most builders’ risk policies have limitations on coverage during transit, or specifically exclude transit not to the job site. This is exactly the exposure an installation floater is designed to cover—materials in-transit that the mechanical contractor controls. |
| HVAC equipment arrives at the project site. The mechanical contractor stores it in a temporary on-site storage structure. Before installation begins, the structure partially collapses during a windstorm, destroying $30,000 worth of equipment | Covered under the general contractor’s builders’ risk if on-site temporary storage is included in the policy. However, if the policy excludes temporary structures or has specific sub-limits for on-site storage, the mechanical contractor faces a shortfall. Many contractors add installation floater coverage as a “first dollar” policy to avoid deductibles on high-value specialty equipment. |
| During installation, the mechanical contractor’s tools (portable ductwork cutter, welding equipment, scaffolding for high access) worth $8,000 are stolen from the job site | Not covered under either builders’ risk or installation floaters. Both policies protect the ductwork itself (the material becoming part of the building) but not the contractor’s tools used to install it. The mechanical contractor needs inland marine coverage for tools and portable equipment. |
| Ductwork is installed and damaged by heavy rain due to improper site drainage (poor workmanship, not a covered peril) | Not covered. Damage resulting from faulty design, workmanship, or maintenance errors is a standard exclusion in builders’ risk policies. The mechanical contractor would be responsible for repair as a warranty obligation. |
| A fire on-site damages the installed HVAC system | Covered under the general contractor’s builders’ risk as a covered peril. |
Key Takeaway: Specialty contractors relying on a general contractor’s builders’ risk policy face significant gaps—materials at their own facility, in-transit risks, and storage risks often fall outside the general contractor’s policy. Using an installation floater alongside the general contractor’s policy ensures comprehensive protection without gaps.
Detailed Analysis: Equipment Coverage by Category
Category 1: Building Systems and Mechanical Equipment
Building systems—HVAC, electrical, plumbing, fire protection, security, and similar infrastructure—receive builders’ risk coverage when destined for permanent installation. According to Procore’s coverage overview, these systems are protected from the moment a property owner takes possession until installation is complete.
The coverage protects against damage from fire, theft, vandalism, weather events, and similar perils. An electrical panel destined for installation is covered if stolen before connection. An HVAC unit is covered if damaged by water intrusion while awaiting installation.
However, the coverage excludes equipment breakdown—damage resulting from mechanical or electrical failure rather than external events. If an HVAC unit fails due to a manufacturing defect or mechanical issue unrelated to an external peril, builders’ risk provides no coverage. The contractor would need separate equipment breakdown insurance to address this exposure.
Category 2: Fixtures, Finishes, and Installed Components
Fixtures permanently affixed to the building—light fixtures, ceiling fans, cabinet hardware, door frames, windows, flooring materials, and similar items—are covered under builders’ risk during storage and installation. These items receive protection because they’re destined to become permanent building components.
The coverage extends to damage during storage in temporary locations on-site or off-site (if the policy permits off-site storage) and during the installation process. Fixtures damaged through weather, fire, theft, or vandalism are reimbursable. However, damage from poor installation, design flaws, or workmanship errors is excluded.
Category 3: Contractor’s Small Tools and Equipment
Hand tools and portable equipment contractors use to perform the work—drills, saws, nail guns, welding equipment, power cords, scaffolding for access, measuring tools, and similar items—do not receive builders’ risk coverage. These tools are temporary equipment used to build rather than equipment becoming part of the building.
Even though these tools may be present on the construction site, they require separate inland marine coverage. Many contractors carry blanket tool coverage that protects all owned tools up to specified limits. Others schedule high-value specialty tools individually. Without this separate coverage, stolen or damaged tools represent uninsured losses falling entirely on the contractor.
Category 4: Heavy Machinery and Mobile Equipment
Bulldozers, excavators, cranes, concrete pumps, generators, air compressors, and similar heavy machinery are specifically excluded from builders’ risk coverage unless the machinery is permanently installed as part of the building system.
A construction company using a rented excavator to grade the site cannot file a builders’ risk claim for excavator damage. A contractor operating a generator to power on-site equipment cannot claim generator breakdown under the project’s builders’ risk policy. These equipment categories require separate contractors’ equipment insurance.
The practical rule is straightforward: if the equipment leaves the site after the project concludes, it’s not covered under builders’ risk. It requires contractors’ equipment insurance instead.
Category 5: Materials in Transit and Temporary Storage
According to Bankrate’s analysis, builders’ risk extends coverage to materials in-transit to the job site and in temporary storage locations before final installation. This coverage addresses a critical vulnerability—materials in motion or awaiting placement are exposed to theft, weather damage, and accidents.
However, not all policies extend uniform transit coverage. Some policies include transit coverage while others limit it, making policy review essential. Similarly, temporary storage locations may be covered only if located on the project site itself. Materials stored at contractor facilities, supplier warehouses, or other off-site locations may be excluded unless specific endorsements extend coverage.
A contractor should clarify with their agent whether transit coverage includes materials shipped from overseas (extended timelines, greater risk) and whether off-site storage at the contractor’s facility is included. If these exposures aren’t explicitly covered, supplemental installation floater coverage fills the gap.
Category 6: Temporary Structures and Site Amenities
Temporary structures erected during construction—scaffolding, temporary fencing, construction office trailers, portable storage containers, and site amenities—sometimes receive builders’ risk protection, though coverage varies significantly by policy.
Some builders’ risk policies include temporary structures as standard coverage, while others require specific endorsements to extend protection. A contractor should verify whether the policy covers temporary structures damaged during the project. If not, the contractor faces exposure for loss or damage to these facilities.
Federal Framework and State Variations
Federal Guidance and Industry Standards
Builders’ risk insurance is not regulated by a single federal statute but rather follows industry standards developed by the Insurance Services Office (ISO) and individual insurance carriers. However, it’s important to note that most builders’ risk policies do not follow the ISO standard form but rather use broader “manuscript” forms written specifically for each project.
This distinction matters significantly. A standard ISO builders’ risk form might be more restrictive than a manuscript form. Conversely, a manuscript form might have unexpected exclusions absent in standard forms. According to legal guides on builders’ risk, contractors and property owners should carefully review their specific policy language rather than assuming standard coverage.
The federal system relies on market competition and contractual freedom rather than specific regulatory mandates. States regulate the insurance market, but most don’t mandate specific builders’ risk coverage requirements for private construction—instead leaving these decisions to individual contracts between property owners and contractors.
California-Specific Requirements and Considerations
California has distinct builders’ risk considerations reflecting the state’s unique risks and regulatory environment. According to the California Department of Insurance oversight of builders’ risk policies, construction projects in California must address wildfire and earthquake risks typically excluded from standard builders’ risk policies.
Earthquake coverage: Standard builders’ risk policies in California exclude earthquake damage. Given California’s seismic activity, contractors and property owners should evaluate whether to purchase earthquake endorsements for valuable projects. A building in a high-seismic-risk area that sustains earthquake damage would have no insurance recovery without specific earthquake coverage.
Wildfire exposure: California’s diverse climate zones present varying weather risks including wildfires, which are typically excluded from standard policies. Projects in high-fire-hazard areas should consider wildfire coverage endorsements.
Permit compliance costs: California has strict building codes. Builders’ risk policies can include ordinance or law endorsements covering the cost to bring damaged property up to current code standards—a significant exposure in California’s stringent regulatory environment.
Project location and documentation requirements: California municipalities vary in their builders’ risk requirements. Some require all parties on a project to verify builders’ risk coverage. Many use American Institute of Architects (AIA) contract forms requiring property owners to obtain builders’ risk insurance. Contractors should verify whether their specific municipality mandates builders’ risk coverage and understand who bears responsibility for procuring it.
Multi-State Considerations
For contractors operating across multiple states, builders’ risk requirements vary significantly:
State-mandated coverage: Some states require builders’ risk insurance for projects above certain values. Others leave coverage entirely optional, delegated to contractual requirements.
Licensed builder requirements: Certain states require licensed contractors to carry specified insurance minimums, potentially including builders’ risk coverage at defined levels.
Lender requirements: Financial institutions financing construction projects often mandate builders’ risk insurance as a condition of funding, regardless of state law. A project’s lender may require coverage even if state law doesn’t mandate it.
Municipal requirements: Cities and counties sometimes mandate builders’ risk coverage for projects above certain values or in specific zones. A contractor should verify local requirements before beginning any project.
Exclusions and Gaps: What Builders’ Risk Does NOT Cover
Understanding what builders’ risk explicitly excludes is as important as understanding what it covers. Common exclusions appear across most policies but may vary by carrier and specific policy form.
Standard Exclusions Affecting Equipment Coverage
Contractor’s equipment: All sources unanimously confirm that equipment not intended to become part of the building is excluded. This includes bulldozers, excavators, generators, air compressors, and other contractor-owned machinery.
Equipment breakdown: Damage from mechanical or electrical failure—components breaking down due to internal defect—is excluded even if the equipment is destined for installation. Equipment breakdown insurance provides separate coverage for these losses.
Employee theft: Theft by employees (rather than outside parties) is typically excluded. If a construction worker steals tools or materials, the loss isn’t covered. This exclusion encourages internal security measures and employee screening.
Faulty design or workmanship: Damage resulting from defective design, poor workmanship, or planning errors is standardly excluded. However, the exclusion’s scope varies across three versions developed by the London Engineering Group (LEG): LEG 1 completely excludes all losses; LEG 2 excludes only rectification costs; and LEG 3 (broadest) excludes only upgrade costs. Understanding which version applies in your policy is critical.
Wear and tear: Normal wear and tear from construction activities is excluded. Damage must result from a specific insured peril, not gradual deterioration.
Water intrusion and settling: Policies commonly exclude damage from water intrusion, settling, cracking, or shrinkage that’s expected in construction. A building’s expected settling won’t be covered. However, unintentional cracking caused by a covered peril (like fire or explosion) typically is covered.
Flood and earthquake: Standard policies exclude flood and earthquake damage, requiring specific endorsements for coverage. These are particularly important in California and coastal areas.
Pollution and mold: Most carriers apply mold and pollution exclusions. Contractors can sometimes negotiate removal of these exclusions if specific conditions are met.
Intentional damage: Intentionally caused damage is excluded. This prevents fraud and protects against deliberate vandalism by the insured themselves.
Coverage Gaps and Sub-Limits
Beyond formal exclusions, builders’ risk policies often include sub-limits—lower coverage amounts for specific types of property—that create practical coverage gaps.
According to Procore’s analysis, items like hot testing, debris removal, offsite storage, and soft costs may have sub-limits differing from policy limits or may not be included at all. A policy with a $5 million limit might have only a $500,000 sub-limit for off-site stored materials. Understanding these sub-limits prevents the unpleasant discovery that coverage you assumed was unlimited carries a much lower actual limit.
Do’s and Don’ts: Best Practices for Equipment Coverage
Do’s: Actions That Protect Equipment Coverage
Do clarify what equipment will become part of the building before purchasing. Equipment destined for permanent installation receives builders’ risk coverage. Equipment used to build does not. Determine this classification early so you can obtain appropriate coverage.
Do carry separate contractors’ equipment insurance for heavy machinery and mobile equipment. Builders’ risk explicitly excludes equipment not becoming part of the building. Rented cranes, owned excavators, generators, and air compressors require separate inland marine coverage.
Do review the specific builders’ risk policy to understand coverage of transit and off-site storage. Not all policies cover materials in transit or stored at contractor facilities. If these exposures matter to your project, confirm coverage exists or obtain installation floater endorsements.
Do verify whether temporary structures like scaffolding and construction trailers are included in the policy. Some policies cover these; others require separate endorsement. Clarifying coverage avoids mid-project disputes.
Do add installation floater coverage when managing specialized high-value materials. If you’re a subcontractor controlling valuable equipment from your facility through installation, an installation floater ensures no coverage gaps between your facility and the job site.
Do document all equipment values and locations at policy inception. Accurate documentation of what’s covered, where it’s stored, and its value prevents underinsurance and claim disputes later.
Do address equipment breakdown coverage separately. Builders’ risk excludes mechanical breakdown. If you operate equipment on-site—generators, pumps, or similar machinery—obtain equipment breakdown insurance covering internal failures.
Do notify your agent immediately if project scope changes or new equipment is added. Equipment added after policy issuance may not be covered unless the policy is endorsed to include it. Don’t assume coverage exists for new equipment.
Do require that any additional parties (specialty contractors, subcontractors) be added as additional insured parties under the policy or carry their own coverage. Unclear coverage responsibility when multiple parties are involved creates claims disputes.
Don’ts: Actions That Create Coverage Gaps
Don’t assume that because a project has builders’ risk coverage, all equipment on the site is covered. The most common mistake is assuming coverage applies to contractor-owned tools and equipment. It doesn’t. These require separate coverage.
Don’t store high-value materials at your facility without verifying coverage exists. Equipment purchased for the project but temporarily stored at your warehouse before transport to the job site may not be covered under the project’s builders’ risk policy. Install a floater or risk uninsured loss.
Don’t rely solely on a general contractor’s builders’ risk policy as a specialty contractor. That policy protects the overall project but may have high deductibles, exclusions, or coverage gaps affecting your specific work. Supplement with your own installation floater covering your materials and work.
Don’t ignore coverage sub-limits for specific exposures. A policy with a $5 million limit might cover off-site storage only up to $250,000. Verify all sub-limits apply to your project’s needs.
Don’t wait until a loss occurs to review your policy. Understanding exclusions and coverage scope before a loss prevents the shock of a claim denial. Review policies at inception and understand specific language.
Don’t assume flood or earthquake coverage is included. These are typically excluded unless specifically added. In high-risk areas, add these endorsements rather than discovering too late that a weather event isn’t covered.
Don’t mix up builders’ risk coverage with general liability coverage. Builders’ risk protects the project itself. General liability protects against bodily injury or third-party property damage claims. You need both; they serve different purposes.
Don’t overlook the “point of possession” timing issue. Builders’ risk may cover materials in transit only to the job site itself. If an expensive fixture is damaged in transit from the supplier to a subcontractor’s facility before it reaches the project site, the coverage may not apply. Plan for this gap.
Pros and Cons: Equipment Coverage Approaches
Approach 1: Relying Solely on General Contractor’s Builders’ Risk Policy
Pros:
✓ Simplicity – One policy for the overall project reduces administrative complexity. Everyone on the site understands that builders’ risk covers the project.
✓ Coverage breadth – A well-structured builders’ risk policy covers all materials and equipment destined for installation, regardless of which subcontractor procured them.
✓ No gaps between parties – When the general contractor obtains comprehensive builders’ risk with all subcontractors added as additional insured, gaps disappear. One policy covers the entire project.
✓ Lower overall costs – A single builders’ risk policy is often cheaper than multiple smaller insurance policies for subcontractors and specialty trades.
Cons:
✗ High deductibles – Builders’ risk policies often have significant deductibles ($15,000–$50,000 or higher). Specialty contractors face exposure for small losses falling below the deductible.
✗ Coverage gaps for subcontractor-specific exposures – The policy covers materials on-site but may not cover materials at the subcontractor’s facility or in transit before job-site arrival.
✗ Potential conflicts over coverage responsibility – When losses occur, disputes arise over whether the general contractor’s policy covers it or whether the subcontractor should have carried separate coverage.
✗ Equipment breakdown excluded – Generators, HVAC units, and equipment breaking down during construction aren’t covered. Separate equipment breakdown insurance is needed.
✗ No coverage for contractor-owned tools – General contractors’ tools and equipment used to build the project aren’t covered. Each contractor needs their own inland marine coverage for tools.
Approach 2: Layered Coverage (General Contractor’s Builders’ Risk + Specialty Contractor Floaters)
Pros:
✓ Comprehensive protection – Combining a broad builders’ risk policy with specialty floaters for subcontractors eliminates coverage gaps. Materials are protected from procurement through installation.
✓ First-dollar coverage for high-value items – Installation floaters cover specialty contractor materials without deductibles, allowing immediate repair or replacement of valuable equipment.
✓ Clear responsibility allocation – When multiple policies are in place, each party understands which coverage applies to their specific work. Claim disputes decrease.
✓ Transit and off-site storage protection – Installation floaters cover materials at the specialty contractor’s facility and in transit—exposures often excluded from builders’ risk.
✓ Addresses equipment breakdown separately – Specialty contractors can add equipment breakdown coverage to their floater, addressing this critical gap in builders’ risk.
Cons:
✗ Higher total costs – Multiple policies cost more than a single policy. The cost of an installation floater for every specialty contractor on a large project multiplies quickly.
✗ Administrative complexity – Multiple policies require coordination, individual reviews of coverage scope, and careful management of additional insured endorsements.
✗ Potential duplicate coverage – Overlap between builders’ risk and specialty floaters means paying for some coverage twice if not carefully coordinated.
✗ Policy coordination issues – Determining which policy is “primary” for specific losses can create disputes between carriers if not clearly established in endorsements.
Approach 3: Contractors’ Equipment Insurance for Tools and Machinery
Pros:
✓ Protects non-project-specific equipment – Coverage follows the contractor’s tools and equipment from job to job rather than being project-specific.
✓ Addresses contractor’s business needs – A contractor operating on multiple projects simultaneously needs coverage that protects equipment across all projects, not just one.
✓ Includes equipment breakdown – Equipment breakdown coverage is typically included in contractors’ equipment policies, addressing a major builders’ risk gap.
✓ Covers rented and owned equipment – Both owned machinery and rented equipment used in construction receive protection.
Cons:
✗ Additional cost – This is coverage beyond builders’ risk, adding to insurance expenses.
✗ No coverage for project-specific materials – This policy protects the contractor’s equipment but not materials purchased for the project that will become part of the building.
✗ Overlap with builders’ risk for on-site equipment – Some coverage overlap can occur if not carefully coordinated, resulting in duplicate payments.
✗ Deductibles – Like builders’ risk, equipment policies carry deductibles that may exceed the value of small losses.
Mistakes to Avoid: Common Equipment Coverage Errors
Mistake 1: Assuming Contractors’ Tools Are Covered Under Builders’ Risk
The error: A contractor purchases a $3,000 power drill, circular saw, and nail gun kit for use on a project covered by builders’ risk insurance. When the tools are stolen from a locked job-site container, the contractor files a claim expecting reimbursement.
Why this fails: Builders’ risk explicitly excludes equipment not becoming a permanent part of the building. Hand tools and portable equipment used to perform the work are not covered. The claim is denied.
The consequence: The contractor loses $3,000 to theft with no recovery. If this pattern continues across multiple projects, the cumulative losses become substantial.
Prevention: Contractors should carry inland marine coverage specifically for tools and portable equipment. This coverage follows the contractor’s equipment from job to job, providing protection regardless of the project’s builders’ risk policy.
Mistake 2: Not Clarifying Equipment Status at Policy Inception
The error: A contractor plans to renovate a commercial space, including installation of new HVAC equipment and use of rented heavy-duty scaffolding. When obtaining builders’ risk insurance, the contractor doesn’t clearly communicate whether the HVAC equipment will be included or which party owns the scaffolding.
Why this fails: The insurance agent can’t properly classify equipment without clear information. The policy is issued with ambiguous or incorrect coverage. Later, when the HVAC unit is damaged, the insurer questions whether it was truly destined for permanent installation or was temporary contractor equipment. Similarly, the rented scaffolding is assumed not covered.
The consequence: A claim for HVAC damage faces potential denial due to ambiguity about equipment classification. The contractor bears the loss cost.
Prevention: Before obtaining builders’ risk insurance, clearly document all equipment that will be on the project. Specify which items become permanent building components (covered) versus which are contractor equipment or rented machinery (not covered). Provide this documentation to the insurance agent at policy inception.
Mistake 3: Ignoring Off-Site Storage and Transit Coverage Limitations
The error: A specialty contractor purchases $45,000 worth of custom HVAC ductwork for a commercial project. The ductwork is manufactured at the contractor’s facility, stored there for two weeks, then transported to the job site. The project has a builders’ risk policy. The specialty contractor assumes coverage applies to the ductwork throughout this process.
Why this fails: Builders’ risk typically covers materials once they arrive at the construction site. Materials at the contractor’s facility or in-transit may not be covered unless the policy specifically includes these exposures. Many policies explicitly exclude materials stored at contractor facilities.
The consequence: Fire damages the ductwork while stored at the contractor’s facility. The contractors’ builders’ risk claim is denied because the equipment wasn’t at the project site. The contractor absorbs a $45,000 loss.
Prevention: Before purchasing expensive project-specific materials, clarify with your insurance agent whether builders’ risk covers materials at your facility and in transit. If not, obtain an installation floater that covers your materials from fabrication through on-site installation.
Mistake 4: Not Addressing Equipment Breakdown Coverage Gaps
The error: A contractor operates a large diesel generator on a construction site to power equipment and temporary facilities. The generator is essential to the project. One week into the project, the generator’s engine fails—a mechanical breakdown unrelated to any external peril. The contractor assumes builders’ risk covers this loss.
Why this fails: Builders’ risk explicitly excludes equipment breakdown resulting from mechanical or electrical failure. The failure must result from an external insured peril (fire, lightning, theft) to be covered. Internal mechanical failures are excluded.
The consequence: The contractor faces a $12,000 generator repair or replacement cost with no insurance recovery. Project delays compound the loss.
Prevention: For on-site equipment prone to breakdown—generators, air compressors, pumps—obtain separate equipment breakdown insurance covering mechanical and electrical failures. This is especially important for owned versus rented equipment, as the contractor bears responsibility for repair.
Mistake 5: Confusing Installation Floater and Builders’ Risk Responsibilities
The error: A plumbing subcontractor purchases expensive fixtures for a project covered by the general contractor’s builders’ risk policy. The subcontractor assumes builders’ risk covers the fixtures from the fixture manufacturer through final installation. The fixtures are damaged in transit to the job site. The subcontractor files a claim under the GC’s builders’ risk policy.
Why this fails: The GC’s builders’ risk policy covers the project once it’s on-site or destined for on-site installation. The scope is the project as a whole. The plumbing fixtures in-transit to the site, or stored at the plumbing contractor’s facility before transport, may not be covered by the GC’s policy. This is exactly what installation floaters are designed to cover.
The consequence: The claim is denied because the fixtures were damaged before reaching the project site. The plumbing contractor absorbs the loss. The contractor learns too late that relying on someone else’s policy was risky.
Prevention: Specialty contractors managing valuable materials from their own facility through installation should carry installation floaters covering their specific materials. Don’t rely on the general contractor’s builders’ risk to cover exposures outside the construction site itself.
Mistake 6: Not Verifying Additional Insured Status
The error: A subcontractor works on a project with builders’ risk coverage. The subcontractor assumes they’re covered by the policy but doesn’t verify whether they’ve been added as an additional insured. When a loss occurs affecting the subcontractor’s work, they file a claim.
Why this fails: Many builders’ risk policies cover only the named insured (usually the general contractor or property owner) and those specifically added as additional insured parties through endorsement. If the subcontractor wasn’t added via endorsement, they have no coverage rights under the policy.
The consequence: The claim is denied because the subcontractor isn’t a covered party under the policy. The subcontractor expected coverage that didn’t exist.
Prevention: Before starting work, confirm with the general contractor in writing that you’ve been added as an additional insured under the project’s builders’ risk policy. If not, obtain your own coverage—either through installation floater or other insurance—to protect your interests.
Mistake 7: Assuming Completed Building Coverage Transitions Smoothly
The error: A construction project is completed and handed over to the owner. The owner assumes their homeowner’s or commercial property insurance now covers all equipment that became part of the building (HVAC, electrical panels, plumbing systems). However, the owner’s policy specifically excludes equipment installed during a prior construction or renovation phase.
Why this fails: The transition from builders’ risk coverage to the owner’s permanent property insurance is not automatic. Owners’ policies often have exclusions or limitations on equipment installed during construction. Coverage gaps can exist during the transition period.
The consequence: Equipment damaged shortly after occupancy is not covered because the owner’s policy excludes it. The owner expected continuous coverage but actually has a gap.
Prevention: Before builders’ risk coverage terminates, review the owner’s permanent property insurance to ensure all equipment that became part of the building is covered. Add endorsements to the owner’s policy if necessary to cover all building systems. Coordinate coverage dates to avoid gaps between when builders’ risk ends and permanent coverage begins.
FAQs: Common Questions About Equipment Coverage
Does builders’ risk cover a rented crane damaged during operation on a construction site?
No. Rented heavy equipment used to build the project requires separate contractors’ equipment insurance. Builders’ risk excludes equipment not becoming a permanent part of the building. The contractor should carry inland marine coverage for rented equipment.
Is HVAC equipment destined for installation covered under builders’ risk if damaged before installation?
Yes. HVAC equipment that will become a permanent building component is covered from the point the owner takes possession through installation. Coverage extends to in-transit damage, temporary on-site storage, and installation phase damage.
If my builders’ risk policy has a $10,000 deductible, do I have to pay that for every claim?
Yes. The deductible applies per claim, so multiple smaller losses each trigger the deductible. Consider higher deductibles to reduce premiums, but ensure your project can absorb that out-of-pocket cost if losses occur.
Are my contractor-owned hand tools covered under a project’s builders’ risk policy?
No. Hand tools, power tools, and portable equipment contractors use to perform work are not covered. These require separate inland marine coverage. Don’t assume coverage for your equipment.
Does builders’ risk cover equipment breakdown if a generator fails mechanically on-site?
No. Equipment breakdown from mechanical or electrical failure is specifically excluded. You need separate equipment breakdown insurance covering mechanical failures.
Can I add my own equipment to a project’s builders’ risk policy if it’s not mentioned in the original policy?
Not automatically. Equipment not specified at policy inception may not be covered. Notify your agent immediately if new equipment is added, and request an endorsement covering it.
Does builders’ risk coverage extend to materials stored at my contractor facility before transport to the job site?
Maybe. Some policies cover temporary off-site storage; many don’t. Verify coverage exists before relying on it. If not included, obtain an installation floater covering your facility.
Who is responsible for obtaining builders’ risk insurance—the property owner or general contractor?
Either party can obtain it, but contract language specifies responsibility. Most AIA construction contracts require property owners to obtain coverage. Check your specific contract to determine who must secure and pay for the policy.
Does builders’ risk cover intentional damage or vandalism caused by site workers?
No. Intentional damage is excluded. Additionally, damage caused by employees (rather than outside vandals) is often excluded. This exclusion encourages internal security and employee screening.
If I’m a specialty contractor working under a general contractor’s builders’ risk policy, do I need my own coverage?
Possibly. If the GC’s policy covers your materials on-site without high deductibles and addresses all your exposures, you may be adequately covered. However, if you control materials before they reach the site or need first-dollar coverage for expensive items, an installation floater protects your interests.
Does builders’ risk cover testing of newly installed equipment?
Usually not. Most policies exclude damage occurring during initial testing of newly installed equipment. If testing is part of your project scope, clarify coverage with your agent and consider specific testing coverage endorsements.
Are temporary structures like scaffolding and construction trailers covered under builders’ risk?
Sometimes. Coverage varies by policy. Some include temporary structures; others require endorsement. Verify coverage before relying on it, especially if scaffolding is critical to your project.
What’s the difference between builders’ risk and the general contractor’s liability insurance?
Completely different purposes. Builders’ risk protects the project itself from physical damage. General liability protects against bodily injury or third-party property damage claims. You need both; neither replaces the other.
Does California’s builders’ risk coverage include earthquake or wildfire damage?
No. Standard California policies exclude both. In high-risk areas, add earthquake and wildfire endorsements to protect against these California-specific perils.
If the general contractor’s builders’ risk policy is canceled mid-project, what happens?
Coverage gaps exist immediately. Any loss occurring after cancellation isn’t covered. Verify that builders’ risk coverage remains continuously in force throughout the entire project. Communicate with the GC if renewal dates approach.
Can an equipment supplier file a builders’ risk claim for equipment damage before it’s delivered to the job site?
Unlikely. Builders’ risk typically protects the project owner and named insured parties. Equipment suppliers usually can’t claim under another party’s policy. Suppliers should maintain their own inland marine coverage for equipment in transit.
Does builders’ risk cover loss of use if equipment is damaged and must be replaced?
Usually not. Standard builders’ risk covers the cost of replacement but not the cost of delays or lost income from being without equipment. Special endorsements can extend coverage to these costs, but they’re not standard.
If a subcontractor causes damage to building materials, is it covered under builders’ risk?
Yes, if it’s a covered peril. If a subcontractor accidentally damages materials (like fire), it’s covered. If damage results from negligence or poor workmanship, it’s typically excluded unless the exclusion is limited to rectification costs only.
What happens to builders’ risk coverage once the building is substantially complete?
Coverage typically ends upon substantial completion. The owner’s permanent property insurance becomes effective. Coordinate coverage dates to avoid gaps. Verify that all equipment installed during construction is covered under the permanent policy.
