Who Qualifies for Proposition 19 Property Tax Transfer?
Justin Borges, DRE #01940318 · 13 min read
Proposition 19 qualifies two distinct groups of California homeowners: parents and children (or grandchildren, if the parents are deceased) transferring a primary residence, and homeowners age 55 or older, severely disabled, or displaced by a wildfire or Governor-declared disaster who are replacing a primary residence. Each group excludes up to $1,044,586 in added value from reassessment, provided the strict move-in and filing deadlines are met.

Who Qualifies for the Prop 19 Parent-Child Transfer Exclusion?
A parent transferring a primary residence to a child, or a child transferring a primary residence to a parent, qualifies for the Proposition 19 exclusion in Los Angeles County as long as the property continues as the transferee's primary residence. This is the transfer that most Los Angeles County families use when a parent's home passes to an adult child after death, or when a family restructures ownership during a parent's lifetime (Revenue and Taxation Code Section 63.1).
Qualifying is not automatic. The transferee must move into the property as a primary residence within one year of the transfer date, and must file the parent-child claim form, BOE-19-P, with the Los Angeles County Assessor. A property that becomes a rental, a vacation home, or stays vacant does not qualify, no matter how close the family relationship.
Most Los Angeles County families assume any transfer between parent and child qualifies. It only qualifies if someone actually lives there within a year and files the paperwork to prove it.
Justin Borges, CA DRE #01940318Who Qualifies for the Grandparent-to-Grandchild Exclusion?
A grandchild qualifies for the same Proposition 19 exclusion only if the grandchild's parents, who would otherwise have qualified as the grandparent's own children, are deceased at the time of the transfer. Los Angeles County assessors apply this rule strictly: a living parent in the middle of the family line blocks the grandchild from qualifying directly, even if that parent has no interest in the property.
- Both parents deceased. The grandchild files BOE-19-G and qualifies on the same terms as a parent-child transfer.
- One or both parents living. The grandchild does not qualify for this exclusion; the property would need to pass through the living parent first.
- Same primary-residence and filing rules apply. Move-in within one year, exemption filing within one year, and the same $1,044,586 exclusion add-on.
Families in Los Angeles County who are planning a multi-generational transfer should confirm which generation is actually deceased before assuming a grandchild qualifies, since this is one of the most common reasons a Prop 19 claim gets denied.
How Much Property Tax Value Can You Exclude Under Proposition 19?
Proposition 19 adds $1,044,586 on top of the factored base year value before reassessment applies, effective February 16, 2025 through February 15, 2027 (BOE Publication 801; BOE News Release NR 25-02). If the property's fair market value at transfer is at or below the factored base year value plus $1,044,586, the original Los Angeles County tax base carries over completely unchanged. Only the amount above that combined figure gets added to the taxable value.
| Factored Base Year Value | Fair Market Value at Transfer | Excluded Amount | Added to Taxable Value |
|---|---|---|---|
| $300,000 | $1,200,000 | $1,344,586 | $0 (no reassessment) |
| $400,000 | $1,800,000 | $1,444,586 | $355,414 added to base |
| $500,000 | $2,500,000 | $1,544,586 | $955,414 added to base |
A Los Angeles County home with a $300,000 factored base year value transfers with no reassessment at all up to a $1,344,586 fair market value. Above that threshold, only the excess above the combined figure gets added to the base, not the entire market value, which is the detail families most often get wrong when estimating a post-transfer tax bill.
Who Qualifies for the Age 55-Plus Base Year Value Transfer?
A homeowner who is at least 55 years old on the date of sale, sells a Los Angeles County primary residence, and purchases or builds a replacement primary residence anywhere in California within two years qualifies to transfer the original factored base year value to the new home. Proposition 19 allows this up to three times in a homeowner's lifetime, up from a single lifetime transfer under the pre-2021 rules, and the replacement home no longer has to sit in the same or a reciprocal county (BOE Publication 801; Revenue and Taxation Code Section 69.6).
Replacement Bought Within Year 1
Replacement Bought Within Year 2
A Los Angeles County homeowner downsizing from a paid-off home into a smaller property, or relocating to be closer to family elsewhere in California, can carry their original tax base forward as long as the replacement is purchased within the applicable value cap. Buying above the cap does not disqualify the transfer entirely; only the amount above the cap gets added to the transferred base.
Do Disabled Homeowners and Wildfire Victims Qualify for Prop 19 Too?
Yes. A severely and permanently disabled homeowner qualifies for the identical base year value transfer available to an age 55-plus homeowner, filing form BOE-19-D along with certification form BOE-19-DC, with no age minimum at all. A homeowner whose Los Angeles County property was substantially damaged, meaning more than half of its market or improvement value was lost, in a wildfire or a Governor-declared disaster qualifies the same way, filing form BOE-19-V (BOE Publication 801).
None of these three qualifying groups, age 55-plus, disabled, or disaster victims, need to buy a replacement home in the same county as the original Los Angeles County property. The replacement can sit anywhere in California, and the same 105 percent (year one) or 110 percent (year two) value caps and three-transfer lifetime limit apply across all three categories identically.
What Are the Filing Deadlines to Qualify for Proposition 19?
Every Proposition 19 category in Los Angeles County runs on its own filing clock, and missing one does not disqualify a family forever, but it does cost the retroactive benefit back to the transfer date.
| Claim Type | Form | Filing Deadline |
|---|---|---|
| Parent-child / grandparent-grandchild exclusion | BOE-19-P / BOE-19-G | Within 3 years of transfer, or 6 months after assessor notice, whichever is later |
| Homeowners' exemption (locks in retroactive date) | BOE-266 | Within 1 year of transfer |
| Age 55+ / disabled / disaster base year value transfer | BOE-19-B / BOE-19-D / BOE-19-V | Within 3 years of replacement purchase or construction completion |
A late filing on any of these Los Angeles County forms still qualifies for the exclusion going forward, but relief only begins in the year the claim is actually filed rather than retroactive to the transfer date itself (Property Tax Rule 462.520). Filing on time is the difference between years of retroactive savings and starting the clock late.
What Disqualifies a Property From a Proposition 19 Exclusion?
Three mistakes account for most denied Proposition 19 claims across Los Angeles County. Understanding them ahead of a transfer prevents a family from losing the exclusion after the fact.
- Non-primary-residence use. A property kept as a rental, a second home, or left vacant after transfer does not qualify, regardless of the family relationship between transferor and transferee.
- Missed one-year deadlines. Moving in after the one-year mark, or filing the homeowners' exemption late, forfeits retroactive relief back to the transfer date.
- Value cap overruns on a base year value transfer. Buying a replacement home above the 105 percent (year one) or 110 percent (year two) cap does not disqualify the whole transfer, but the excess above the cap gets added to the transferred taxable value.
Family farms are treated differently: there is no requirement that a transferee actually live on a qualifying family farm parcel, defined under Government Code Section 51201 as land under cultivation, pasture, or agricultural production, which is an exception worth knowing for Los Angeles County families holding agricultural land at the county's outer edges.
Frequently Asked Questions
Who qualifies for the Proposition 19 parent-child exclusion in California?
A parent transferring a primary residence to a child, or a child transferring to a parent, qualifies for the Proposition 19 exclusion as long as the transferee moves in and files for the homeowners' exemption within one year of the transfer (Revenue and Taxation Code Section 63.1; BOE Publication 801).
Can grandchildren qualify for a Proposition 19 property tax transfer?
Yes, but only if the grandchild's parents, who would otherwise qualify as the grandparent's children, are deceased at the time of transfer. The same primary-residence and filing-deadline rules apply (BOE Publication 801).
How much property value can you exclude under Proposition 19?
Proposition 19 adds $1,044,586 on top of the factored base year value before any reassessment applies, effective February 16, 2025 through February 15, 2027. If the fair market value at transfer is below that combined figure, the original tax base carries over unchanged (BOE Publication 801; BOE News Release NR 25-02).
Who qualifies for the age 55-plus Proposition 19 base year value transfer?
A homeowner who is at least 55 years old, sells a primary residence, and buys or builds a replacement primary residence anywhere in California within two years qualifies to transfer their factored base year value, up to three times in their lifetime (Revenue and Taxation Code Section 69.6; BOE Publication 801).
Do wildfire victims qualify for Proposition 19 relief?
Yes. A homeowner whose property was substantially damaged, meaning over half of its market or improvement value was lost, in a wildfire or a Governor-declared disaster qualifies for the same base year value transfer as an age 55-plus homeowner, with no age requirement (BOE Publication 801).
What is the filing deadline to qualify for a Proposition 19 exclusion?
The parent-child or grandparent-grandchild claim form (BOE-19-P or BOE-19-G) must be filed within three years of the transfer, or six months after an assessor's notice, whichever is later. The homeowners' exemption (BOE-266) must separately be filed within one year of transfer to receive the exclusion retroactive to the transfer date (BOE Publication 801).
What disqualifies a Los Angeles County homeowner from a Proposition 19 exclusion?
The most common disqualifiers are missing the one-year move-in and exemption-filing deadlines, transferring a property that is not the decedent's or transferor's primary residence, and, for the age 55-plus transfer, buying a replacement home above the 105 or 110 percent value cap without accepting a partial addition to the taxable value (BOE Publication 801).
