California Form BOE-19-V is the Claim for Transfer of Base Year Value to Replacement Primary Residence for Victims of a Wildfire or Other Natural Disaster, and it lets a California homeowner whose principal residence was substantially damaged or destroyed by a Governor-declared disaster move the old home’s lower property tax base to a new primary residence anywhere in the state. The form is filed with the county assessor in the county where the replacement home sits, and it is the practical doorway to the relief created by Proposition 19 and codified in Revenue & Taxation Code §69.6.
The current revision date printed on the form is May 2021, which is the version the California State Board of Equalization prescribes for use statewide. According to BOE published Letters to Assessors, thousands of disaster victims fail to claim this transfer each year, often because they miss the 2-year replacement window or the 3-year filing deadline. A single missed box on this form can cost a homeowner tens of thousands of dollars in property tax over the life of the new home.
Here is what this guide gives you:
- 🏠 A line-by-line walkthrough of every part, box, and signature block on BOE-19-V
- 📅 The exact deadlines, value caps, and “substantially damaged” rules that decide if you qualify
- 🧾 A pre-filing checklist of the documents you must gather before opening the form
- 👨👩👧 Three full filled-out scenarios from real disaster fact patterns
- ⚠️ The most common mistakes filers make and the dollar consequences of each
What the Form Is and Who Must File It
BOE-19-V is the official Proposition 19 claim form for disaster victims who want to carry their old property tax base year value over to a replacement primary residence. The relief is grounded in Article XIII A, Section 2.1(b) of the California Constitution and implemented through Revenue & Taxation Code §69.6. Without this form, the new home gets reassessed at full market value, which often means a property tax bill many times larger than the one the family paid before the disaster.
You must file BOE-19-V if you owned and lived in a California home that was substantially damaged or destroyed by a wildfire or other natural disaster declared by the Governor, and you bought or built a replacement primary residence anywhere in California within 2 years of the damage. “Substantially damaged” means the improvements lost more than 50% of their full cash value just before the disaster, a standard explained in BOE Letter to Assessors 2021/019. The form applies to both same-county and different-county replacements, which is a major expansion over the old Proposition 50 and Proposition 171 rules.
The form is not for renters, not for second homes, and not for commercial property. It is also not the same as BOE-19-B (age 55+ transfer) or BOE-19-D (severely disabled transfer), although the same household can sometimes choose between forms if more than one type of relief applies. Filers must have actually occupied the damaged home as their principal place of residence at the time of the disaster, and they must occupy the replacement as their principal residence as well.
Imagine Maria Lopez, a retired teacher whose Paradise home burned in the 2018 Camp Fire. She rebuilt her life in Chico, bought a new home there in 2024, and used BOE-19-V to keep her 1997 base year value. Without the form, her property taxes would have tripled overnight.
Before You Start: Documents and Information You Need
Gather every document below before you open the form, because missing items are the single biggest reason claims sit in pending status at the county assessor’s office. The California Association of Clerks and Election Officials and most county assessor handbooks recommend a single folder containing all of the following items.
- Assessor’s Parcel Number (APN) of the damaged home. You will find it on the last property tax bill or on the county assessor’s parcel viewer, and the assessor uses it to pull your old base year value.
- APN of the replacement home. Pull this from the recorded grant deed or the new tax bill, because it ties the transfer to the right new parcel.
- Recorded grant deed for the replacement property. The assessor confirms ownership and purchase date from this document, and a missing deed will pause the claim.
- Date of the disaster and the Governor’s proclamation reference. The list lives at CalOES Proclamations, and the assessor uses it to confirm your event qualifies.
- Proof of substantial damage. Insurance loss reports, FEMA letters, a Cal Fire damage inspection, or county building department records all work, because the assessor must verify the more-than-50% improvement loss test.
- Full cash value of the original property just before the disaster. Get this from the assessor’s records or your insurance declaration page, because the value cap math in Part 4 depends on it.
- Purchase price or new construction cost of the replacement. Pull this from your closing statement or builder contract, because it sets the comparison value used in the partial-relief formula.
- Driver’s license or California ID showing both addresses. The assessor uses these to confirm principal residence status, and a P.O. Box alone will not satisfy occupancy.
- Homeowners’ Exemption BOE-266 for the new home. A claimed homeowners’ exemption is the simplest way to prove principal residence on the replacement.
- Spouse or co-owner information. Names, signatures, and ownership percentages must match the deed, because mismatches trigger requests for additional documents.
Where to Get the Form and How to Access It
The official PDF lives on the BOE proposition 19 forms page, and most counties also post a fillable version on their assessor websites. Examples include the Los Angeles County Assessor, the Sonoma County Assessor, the Butte County Assessor, and the San Diego County Assessor. Filing the BOE master version is acceptable in every county, even if the county has its own branded copy.
You can fill the form three ways. Type directly into the fillable PDF using Adobe Acrobat or any modern browser, print and complete by hand using black ink, or use an online filing portal where the county offers one (Los Angeles, Orange, and Santa Clara counties currently do). Hand-printed forms must be legible and in block capitals, because scanning errors on cursive entries cause data-entry mistakes that delay processing.
The form is free to download and free to file. Be sure to confirm you are using the May 2021 revision printed at the top of page 1, since older Proposition 50 and Proposition 171 forms are no longer accepted for events on or after April 1, 2021. If you need a paper copy mailed to you, every county assessor’s office will send one on request, and many public libraries in disaster-affected counties keep them on hand.
Step-by-Step: How to Fill Out BOE-19-V Line by Line
The form has a heading block, four numbered parts, a certification, and a signature section. Work through each section in order, because later parts pull data from earlier parts and skipping fields creates downstream errors. Use the official instructions printed on pages 3 and 4 of the PDF as your second reference.
Heading: Assessor’s Office Name and Mailing Address
The top of page 1 asks you to address the form to the assessor’s office of the county where the replacement property sits. Write the county name on the first line and the assessor’s official mailing address below it.
You enter the county name in plain English (for example, Butte County Assessor) and the full street address from the county assessor directory. Use the mailing address, not the public counter address, unless you plan to hand-deliver. Maria Lopez writes Butte County Assessor, 25 County Center Drive, Suite 100, Oroville, CA 95965 in this block.
A common nuance: if your replacement home is in a different county than the damaged home, the replacement county is the right address every time. Filers sometimes mail the form to the original county out of habit, and the form bounces back weeks later. The misconception that “BOE-19-V goes to the BOE” is also widespread, but the State Board of Equalization does not process individual claims.
Name(s) of Claimant(s)
This box asks for the legal names of every person who owns the replacement home and is claiming the transfer. Print first, middle, and last names exactly as they appear on the recorded deed.
Use block capitals if you are hand-writing, and separate co-owners with the word and. Maria Lopez and David Lopez would write both names on one line. If a trust holds title, list the trustee and trust name (for example, Maria Lopez, Trustee of the Lopez Family Trust dated 06/12/2010).
A nuance worth flagging is married couples where one spouse owns the home as separate property. Only the owning spouse is the claimant, although both must usually sign. The most common mistake here is listing only one co-owner when two are on the deed, which causes the assessor to deny the claim for the un-listed owner’s share. The misconception that “the assessor knows who owns the house” is wrong; the assessor cross-references the names you write against the recorded deed letter for letter.
Mailing Address and Daytime Phone
This block asks where the assessor should mail correspondence and which phone number to call with questions. Write your current mailing address, even if it is temporary post-disaster.
Use the standard format Street, City, State ZIP and a 10-digit phone number. Maria Lopez enters 123 Recovery Lane, Chico, CA 95928 and (530) 555-0142. A P.O. Box is acceptable here because this is a mailing address, not the property address.
The nuance to flag is that disaster survivors often live in temporary housing or with family. Use the address where you actually receive mail today, because the assessor sends both approval letters and document requests by U.S. mail. The most common mistake is writing the damaged home’s address out of habit, which causes notices to go to a destroyed mailbox. The misconception that “email is fine” does not apply on this form; only the box you fill in receives notices.
Part 1: Replacement Primary Residence Information
Part 1 captures every detail about the new home, and the assessor uses these fields to confirm location, ownership, and timing. Each line in Part 1 maps to a public record the assessor will pull.
Line A: Address of Replacement Primary Residence
This line asks for the street address of the new home. Write the full situs address as it appears on the recorded grant deed.
Format it as Street Number, Street Name, City, CA, ZIP. Maria Lopez writes 789 Phoenix Way, Chico, CA 95926. Do not abbreviate the city name, and do not list a unit number unless it appears on the deed.
A nuance: rural properties sometimes have both a 911 address and a legacy route-and-box address. Use the 911 address, because that is what the assessor’s GIS system recognizes. The most common mistake is using the mailing address (P.O. Box) instead of the situs address, which prevents the assessor from matching the parcel. The misconception that “the APN is enough” is wrong; both the APN and the situs address are required.
Line B: Assessor’s Parcel Number of Replacement Property
This line asks for the APN of the new home. The APN is the unique identifier the assessor uses to track every parcel.
Pull the APN from the new tax bill or the county parcel viewer, and write it in the exact punctuation the county uses (some counties use dashes, others use spaces). Maria Lopez writes 013-450-022-000.
A nuance: brand-new subdivisions sometimes have placeholder APNs that change after the first roll. Use the APN listed on the most recent tax bill or assessor letter. The most common mistake is transposing digits, which sends the claim to the wrong parcel record. The misconception that “the APN on Zillow is fine” is dangerous; only the official assessor APN is correct.
Line C: Date of Purchase or New Construction Completion
This line asks when you bought or finished building the replacement. The date determines whether the 2-year window from the disaster has been met.
Write the date in MM/DD/YYYY format. For a purchase, use the recording date of the grant deed. For new construction, use the date the building department signed the final inspection or certificate of occupancy. Maria Lopez writes 03/15/2024.
A nuance: if you bought a partially-built home and finished it, the relevant date is the completion date, not the purchase date, under the rules in BOE LTA 2021/019. The most common mistake is using the contract date or the close-of-escrow check date instead of the recording date. The misconception that “my realtor’s date is good enough” leads to denials when the recording date is even one day past the 2-year mark.
Line D: Purchase Price or New Construction Cost
This line asks for the dollar amount you paid (or the cost of new construction). The figure must match the recorded deed transfer tax or the verified construction cost.
Write the number with no dollar sign and no commas, or with commas if the form box has separators. Maria Lopez writes 485,000. Include the cost of land if you bought a lot and built on it.
A nuance: if you received a gift of equity or a non-arm’s-length discount, write the actual market value, not the discounted price. The most common mistake is omitting the value of land for new construction, which understates the new home’s full cash value and can cost the filer some of the partial-relief benefit. The misconception that “the assessor will figure out the price” leaves the field blank, which guarantees a follow-up letter.
Line E: Date of Occupancy as Principal Residence
This line asks when you moved in. The assessor uses this to confirm principal residence status.
Write the date in MM/DD/YYYY. For most filers, this is the date the moving truck arrived. Maria Lopez writes 04/01/2024.
A nuance: if the home was occupied by tenants when you bought it and you moved in later, use the move-in date. The most common mistake is writing the close-of-escrow date when you actually moved in months later, which can cause an occupancy mismatch when the assessor compares utility records. The misconception that “buying it is the same as occupying it” is wrong; occupancy is a separate factual test.
Part 2: Original Primary Residence Information
Part 2 captures details of the destroyed home. The assessor will pull the historical roll value, but you must give them enough to find it.
Line A: Address of Original Primary Residence
Write the situs address of the damaged or destroyed home. Use the address that was on file just before the disaster.
Format as Street, City, CA, ZIP. Maria Lopez writes 47 Skyway Lane, Paradise, CA 95969.
A nuance: many destroyed homes had address changes after the disaster as parcels were rebuilt or merged. Use the pre-disaster address. The most common mistake is using a new post-rebuild address, which the assessor cannot match to the historical record. The misconception that “the address doesn’t matter because the home is gone” is wrong; the address is how the assessor finds the historical base year value.
Line B: Assessor’s Parcel Number of Original Property
Write the APN of the damaged home. Pull it from the last property tax bill issued before the disaster.
Maria Lopez writes 052-280-013-000. Use the punctuation the original county uses.
A nuance: post-disaster reassessments sometimes split or merge parcels, so the current APN may differ from the historical one. Use the historical APN. The most common mistake is using the post-disaster APN, which leads the assessor to a depressed or misure value. The misconception that “any APN that works will do” is dangerous; the assessor cross-checks with the deed history.
Line C: County of Original Primary Residence
This line asks which California county the damaged home sat in. Write the county name in plain English.
Maria Lopez writes Butte.
A nuance: a few California addresses straddle county lines. Use the county shown on the property tax bill, not the postal city. The most common mistake is writing the city instead of the county. The misconception that “Paradise is in Paradise County” is wrong; Paradise is in Butte County.
Line D: Date of Damage or Destruction
This line asks when the disaster occurred. Use the start date of the Governor-declared disaster.
Write MM/DD/YYYY. Maria Lopez writes 11/08/2018 for the Camp Fire.
A nuance: multi-day disasters use the first day of damage to the property, which is sometimes earlier than the official containment or end date. The most common mistake is using the proclamation signing date, which can be days after damage began. The misconception that “any date during the fire is fine” causes math errors in the 2-year replacement clock.
Line E: Governor’s Proclamation Date
Write the date the Governor proclaimed the state of emergency. The full list lives at CalOES.
Maria Lopez writes 11/09/2018 for Camp Fire-related proclamations.
A nuance: some events have multiple proclamations (initial, expansion, extension). Use the proclamation that names the county where your damaged home sat. The most common mistake is leaving the line blank because the filer cannot find it. The misconception that “FEMA declaration is the same as Governor’s proclamation” is wrong; only the Governor’s proclamation triggers BOE-19-V.
Line F: Full Cash Value Just Before Damage
This line asks for the original home’s market value the moment before the disaster. Pull this from the assessor’s pre-disaster roll value plus any contemporaneous appraisal.
Maria Lopez writes 420,000. Include both land and improvements.
A nuance: if you had a Proposition 8 reduced assessment in place, use the factored base year value or the market value, whichever the assessor used last. The most common mistake is writing only the improvement value or only the insurance settlement amount. The misconception that “insurance value equals full cash value” is wrong; insurance often excludes land and may use replacement cost rather than market value.
Line G: Whether Damage Exceeded 50% of Improvement Value
This line is a yes-or-no test. Check Yes only if the improvements lost more than half of their pre-disaster full cash value.
Maria Lopez checks Yes because her Paradise home was a total loss.
A nuance: partial losses sometimes feel “substantial” but fall under the 50% threshold once the assessor measures only improvement loss (excluding land). The most common mistake is checking Yes when only land was affected (mudslide debris on a still-standing house). The misconception that “any major damage qualifies” is wrong; only improvement loss above 50% qualifies under R&T §69.6.
Part 3: Sale of Original Property (If Applicable)
Part 3 applies if you sold the damaged property (or its remaining lot) after the disaster. Many filers do sell the burned-out lot, and the sale figures matter for the value-cap math.
Line A: Date of Sale
Write the recording date of the deed transferring the damaged parcel. Use MM/DD/YYYY.
Maria Lopez writes 06/20/2023.
A nuance: if you have not yet sold the damaged parcel, leave Part 3 blank and the assessor will use only the pre-disaster full cash value. The most common mistake is using the listing date or escrow opening date. The misconception that “you must sell to qualify” is wrong; sale is optional under Prop 19.
Line B: Sale Price
Write the gross sale price of the damaged parcel.
Maria Lopez writes 95,000 (the bare lot’s value).
A nuance: if the buyer paid in installments or with seller financing, write the contract price, not the cash received to date. The most common mistake is writing the net proceeds after liens. The misconception that “sale price equals new full cash value” ignores the §69.6 formula, which uses the greater of pre-disaster value or sale price plus inflation factors.
Part 4: Transfer of Base Year Value Calculation
Part 4 is where the math happens. The assessor will redo the math, but you must show your work to make the claim processable.
Line A: Factored Base Year Value of Original Property
Write the factored base year value (the Proposition 13 number that grew at up to 2% per year). Pull it from the last pre-disaster tax bill.
Maria Lopez writes 118,500.
A nuance: trended factored value is not market value. It is usually much lower. The most common mistake is writing the market value or the insurance value here. The misconception that “the base year value is what I paid in 1997” forgets the annual 2% inflation factor, which compounds over decades.
Line B: Full Cash Value of Replacement Property
Write the assessed full cash value of the new home as of the date of purchase or completion. This is normally the purchase price.
Maria Lopez writes 485,000.
A nuance: if you got a non-arm’s-length deal, use market value. The most common mistake is using the future assessed value rather than the value on the date of purchase. The misconception that “the assessor’s later appraisal counts” is wrong; the date-of-purchase value drives the calculation.
Line C: Full Cash Value of Original Property Just Before Damage
Re-enter the value from Part 2, Line F.
Maria Lopez writes 420,000.
A nuance: this line must match Part 2, Line F to the dollar. The most common mistake is recomputing it differently. The misconception that “rounding is fine” is dangerous; mismatched numbers trigger desk audits.
Line D: Whether Replacement Value Exceeds Original Value
If Line B is greater than Line C, check Yes and compute the excess on the next line. If not, check No and the entire Line A transfers in full.
Maria Lopez checks Yes because 485,000 exceeds 420,000.
A nuance: the comparison uses the original’s pre-disaster value, not the post-disaster value. The most common mistake is comparing to the burned-out lot value. The misconception that “any new home means a tax increase” is wrong; equal or lesser-value replacements transfer the base value with no addition.
Line E: Excess Value Added to Transferred Base
Subtract Line C from Line B. The excess is added to the transferred base year value to form the new home’s base.
Maria Lopez writes 485,000 − 420,000 = 65,000. Her new base year value becomes 118,500 + 65,000 = 183,500.
A nuance: the rule is in R&T §69.6(b)(2) and is sometimes called the “blended base.” The most common mistake is adding the full replacement value instead of just the excess. The misconception that “more expensive means full reassessment” is wrong; only the excess gets reassessed.
Certification and Signature
Every claimant must sign and date this section under penalty of perjury. Print name, sign, write daytime phone, and enter the date.
Maria Lopez prints Maria Lopez, signs, writes (530) 555-0142, and dates 04/10/2024. Co-owners each sign on a separate line.
A nuance: trustees sign in their trustee capacity (for example, Maria Lopez, Trustee). The most common mistake is missing a co-owner’s signature, which voids the claim for that owner’s interest. The misconception that “one spouse signs for both” is wrong on community property held in joint title.

How to File the Completed Form
File BOE-19-V with the assessor of the county where the replacement property sits. Do not mail it to the BOE in Sacramento. Filing is free in every California county.
- By mail. Use the address listed in the BOE county contacts directory. Send certified mail with return receipt; processing takes 30–90 days. Keep the green card as proof of filing.
- In person. Bring two copies to the county counter; the clerk stamps one as your proof. Counter hours and addresses appear on each county assessor’s website (for example, LA County and Sonoma County).
- Online portal. Counties such as Santa Clara, Orange, and San Diego accept upload through their property assessment portals. The portal returns a confirmation email; save the PDF.
- By fax or email. A handful of counties accept faxed or emailed claims; check the county website first because fax intake is being phased out statewide.
There is no filing fee for BOE-19-V itself, but a recorded grant deed (already in your packet) will have its own recording fee paid earlier. Processing time depends on volume; the BOE annual report shows median processing of about 60 days. Always keep a stamped or scanned copy of your claim and a copy of the certified mail receipt.
The 3-year filing deadline runs from the date you purchased or completed the replacement, under R&T §69.6(f). Late claims may still receive prospective relief from the lien date of the year the claim was filed, but you lose any retroactive refund for prior years.
What Happens After You File
The county assessor reviews your claim, pulls the historical roll for the damaged property, and verifies the disaster qualifies under the Governor’s proclamation list. The assessor issues a written decision and updates the new home’s roll value to the blended base year value.
If approved, your next property tax bill reflects the transferred base. If approved retroactively, the assessor issues refunds for any over-paid taxes since the date of purchase, usually through the county auditor-controller. Refunds typically arrive within 60 days of approval.
If denied, you receive a written notice with reasons. You can appeal to the local Assessment Appeals Board within 60 days, file a refund claim, or, in some counties, request informal reconsideration. Most denials trace back to fixable paperwork problems rather than substantive ineligibility.
The assessor may request additional documents (insurance loss reports, FEMA letters, deed copies). Respond within 30 days, because non-response causes automatic denial. Imagine David Chen, who responds late to a Cal Fire damage report request and loses three months of refund.
Mistakes to Avoid When Filling Out the Form
- Filing with the wrong county assessor. The replacement county controls; misrouted claims sit unprocessed for weeks.
- Missing the 2-year replacement deadline. A purchase even one day past the second anniversary of damage is denied outright.
- Missing the 3-year filing deadline. You forfeit retroactive refunds for prior tax years.
- Using the post-disaster APN for the original property. The assessor cannot match the historical base year value.
- Writing market value instead of factored base year value on Part 4 Line A. This wildly overstates the transferred base and the assessor will correct it, often after months of back-and-forth.
- Checking Yes on the 50% damage line for a partial loss. The assessor disqualifies the claim and you lose access to BOE-19-V relief.
- Listing only one co-owner when two are on title. The un-listed co-owner’s interest gets reassessed at full market value.
- Using the close-of-escrow date instead of the recording date. The 2-year clock is measured against the recording date.
- Forgetting to attach proof of damage. The assessor cannot verify the 50% test, and the claim sits in limbo.
- Not filing a Homeowners’ Exemption BOE-266 on the new home. The assessor uses the exemption as the simplest principal residence proof.
- Confusing BOE-19-V with BOE-19-B. Age-55 transfers use a different form and different rules.
- Leaving Part 3 blank when the original was sold. The blended-base math depends on knowing whether a sale occurred.
Do’s and Don’ts
- Do confirm the May 2021 revision date at the top of the form, because old Prop 50/171 forms are no longer valid for post-April 2021 events.
- Do mail by certified mail with return receipt, because that green card is your proof of timely filing.
- Do attach the Governor’s proclamation reference number, because it speeds the assessor’s eligibility check.
- Do keep a scanned copy of every page, because paper files are sometimes lost in busy assessors’ offices.
- Do file the Homeowners’ Exemption BOE-266 at the same time, because it pairs naturally with principal residence proof.
- Do call the county assessor before filing if any field is unclear, because a five-minute call saves weeks of correspondence.
- Don’t mail the form to the BOE in Sacramento, because the BOE does not process individual claims.
- Don’t mix up factored base year value and market value, because Part 4 depends on the correct distinction.
- Don’t sign for your spouse, because community property requires each spouse’s actual signature.
- Don’t use whiteout or correction tape, because altered forms are returned for re-execution.
- Don’t assume the assessor will fill in missing data, because incomplete forms are denied without prejudice and the clock keeps running.
- Don’t wait until the third year to file, because document gathering takes longer than you expect after a disaster.
Pros and Cons of Filing on Your Own vs. With Help
| Filing on Your Own | Filing With a Professional |
|---|---|
| Free and immediate | Usually $300–$1,500 in fees |
| Full control of timing and accuracy | Faster turnaround if you are still in disaster recovery |
| Forces you to learn your own tax position | Avoids errors on the 50% damage and value-cap math |
| Direct contact with county assessor staff | Buffer between you and the assessor during stressful months |
| Works well for simple, single-owner cases | Works well for trusts, LLCs, and multi-owner cases |
Pros of self-filing include cost savings, direct learning, and faster control over the file. Pros of professional help include error reduction, especially for the Part 4 math, and emotional bandwidth relief in the months after a disaster. Cons of self-filing include the steep learning curve and the high cost of a single missed checkbox. Cons of professional help include fees, scheduling delays, and the risk of a preparer who has never filed BOE-19-V before; ask any preparer how many they have filed in the last three years before hiring.
FAQs
Do I file BOE-19-V with the BOE or with my county?
No. File with the county assessor in the county where your replacement primary residence is located. The BOE prescribes the form but does not process individual claims.
Can I transfer the base year value to a home in a different county?
Yes. Proposition 19 allows transfer to any of California’s 58 counties. The replacement county’s assessor processes the claim.
What counts as a “natural disaster” for BOE-19-V?
Yes, any wildfire or natural disaster covered by a Governor-declared state of emergency qualifies. The list of qualifying events lives at CalOES.
How long do I have to buy a replacement home?
Yes, within 2 years from the date of damage. A late purchase, even by one day, disqualifies the claim under R&T §69.6.
How long do I have to file BOE-19-V after I buy the replacement?
Yes, 3 years from purchase or new construction completion. Filing later forfeits retroactive refunds but may still allow prospective relief.
Do I have to sell the damaged property to qualify?
No. Sale of the original is optional. The 50%-improvement-loss test is what qualifies the original home, not its sale.
Do I write the original APN or the replacement APN in Part 1, Line B?
Yes, the replacement APN goes in Part 1 Line B. The original APN goes in Part 2 Line B.
Should I list factored base year value or market value on Part 4 Line A?
Yes, factored base year value only. Market value belongs on Line C, not Line A.
Do both spouses need to sign?
Yes, when both spouses are on title or when the property is community property. A single signature voids the un-signed spouse’s interest.
Can I file BOE-19-V if my home was only partially damaged?
No, unless improvements lost more than 50% of full cash value. Below that threshold, look at BOE-19-B or other relief.
Does my replacement have to cost the same or less than the original?
No. Equal or lesser-value replacements transfer the full base. More expensive replacements add only the excess to the transferred base.
Do I need to attach the Governor’s proclamation?
No, but writing the proclamation date and the disaster name speeds review. Most county assessors verify it themselves through CalOES records.
Can a trust file BOE-19-V?
Yes, when the trust holds title and the trustor-beneficiary lived in the home as principal residence. The trustee signs in trustee capacity.
What if my replacement is new construction on the original lot?
Yes, rebuilding on the original lot can qualify as a replacement under BOE LTA 2021/019, provided improvements are completed within 2 years of damage.
