Prop 19 California: 55+ Move and Parent-Child Rules, 2026

Two rules that share a name

Proposition 19 rewrote two pieces of Proposition 13 at once, and most pages blur them. One lets an older owner move without resetting the tax bill. The other limits what a child inherits. The Constitution’s own statement of intent pairs them: limit tax increases for seniors and the severely disabled who “need to move closer to family or medical care, downsize, find a home that better fits their needs,” and limit them on family homes, “while eliminating unfair tax loopholes used by East Coast investors, celebrities, wealthy non-California residents, and trust fund heirs” (Article XIII A, section 2.1(a)).

The 55+ move: how the number is built

The Constitution says an owner over 55, severely disabled or a disaster victim “may transfer the taxable value of their primary residence to a replacement primary residence located anywhere in this state, regardless of the location or value of the replacement primary residence,” purchased or built “within two years of the sale” (Article XIII A, section 2.1(b)(1)). The statute, section 69.6, adds the conditions the assessor checks:

• Age or disability on the day the old home sells. A buyer who is 54 when the old home sells does not qualify even if 55 at the closing of the new one; a spouse who is over 55 and on both titles can be the claimant (BOE Letter To Assessors 2024/044).
• The old home is a principal residence eligible for the homeowners’ or disabled veterans’ exemption, as of the sale or within two years of buying or finishing the replacement.
• You live in the new home when you file, and the old home is sold within two years of the replacement purchase. One of the two transactions may predate April 1, 2021 (69.6(b)(5)(A)).
• You are a person. A legal entity cannot be the buyer; the BOE’s answer is “Generally, no. In order to qualify the transaction must be completed by a person.”
• Count of transfers: “A person shall not be allowed to transfer the taxable value of a primary residence pursuant to this section more than three times.” The BOE counts a couple as potentially six (three per spouse) and does not count a disaster transfer toward the three.

The value test is the part nobody tabulates. Under 69.6(d)(13) the replacement is “equal or lesser” if its full cash value does not exceed 100 percent of the old home’s value when bought before the sale, 105 percent when bought in the first year after the sale, 110 percent in the second year. Above that, section 69.6(e)(3) adds the gap to the old taxable value.

One old home, six replacement choices (our arithmetic, assumed figures). The old home sells for $1,800,000 with a factored base year value of $400,000. Thresholds: $1,800,000 (100 percent), $1,890,000 (105 percent), $1,980,000 (110 percent). The last column uses an assumed total property tax rate of 1.1 percent, which is our assumption and not a legal rate; it ignores inflation factoring between sale and purchase and any local special assessments.

Two things stand out. The break does not depend on trading down: the buyer of a $2,200,000 home still carries $400,000 of base value plus only the excess over the threshold. And the order of the deals matters twice. Buying first puts you on the 100 percent line instead of the 105 or 110 percent lines, and the BOE warns that buying before selling means “you will be responsible for property taxes based on the full fair market value of the replacement home for the period between the date of purchase and date of sale. There will be no refund for this period.”

The BOE’s own examples fit the same formula: an original with market value $400,000 and factored base year value $100,000, and a $600,000 replacement bought in the first year, gives 105 percent of $400,000, or $420,000, an excess of $180,000 and a taxable value of $280,000. In Letter To Assessors 2024/044 the replacement of $750,000 against $735,000 gives $346,223.

Hard edges the BOE confirms:

• The two-year window has no hardship exception. For new construction the BOE writes: “There are no provisions for any exception due to hardship or other factors which may have prevented compliance with the” two-year period, which is in the Constitution.
• File form BOE-19-B with the assessor of the county of the replacement home within three years of buying it or finishing construction (69.6(c)(1)). A later claim only helps from the lien date of the year it is filed (69.6(c)(2)).
• If you sell the old home to your child and the child gets the heir-type exclusion, “the base year value may not be transferred to a replacement dwelling” (Letter To Assessors 2024/044, question 11).
• Having used the old one-time Proposition 60/90 transfer does not use up the new three, per the BOE’s FAQ.

The heir’s exclusion: the family home and a cap that moves

Section 63.2(a)(1) excludes from change in ownership a transfer between parents and children of the parent’s principal residence, if “The transfer is required to be of a principal residence of the transferor, and become the principal residence of the transferee within one year of the transfer.” The transferee must also file the homeowners’ or disabled veterans’ exemption within a year (63.2(a)(1)(B)). The BOE’s FAQ answers the question investors ask: “the transfer of a rental home between parents and children would not qualify for the exclusion.” Our pages on the California transfer on death deed and deeding a house into a living trust cover how the home gets to the child; the property-tax result is decided here.

The new taxable value is the parent’s factored base year value plus, if the home’s market value is “equal to or more than the sum of the taxable value described in paragraph (1) plus one million dollars ($1,000,000),” the excess (63.2(d)). The Constitution makes the $1,000,000 move every other February 16 with the FHFA house price index for California (section 2.1(c)(4)), and the BOE publishes the figure:

Note for older pages, including some of ours: the statute’s text still says $1,000,000, but for a death today the number is $1,044,586.

What the cap does to a real bill (our arithmetic, assumed figures). A parent’s home has a factored base year value of $300,000 and passes to a child who moves in. Cap: $300,000 + $1,044,586 = $1,344,586. The 1.1 percent rate is our assumption.

The BOE’s own example uses the old round $1,000,000: a $300,000 base and a $1,500,000 home give $500,000. At the current amount the same house comes out at $455,414 (our arithmetic), so the date of death can move a taxable value by tens of thousands of dollars. The lesson for a $250,000+ family is that the exclusion is a fixed-size shelter of about $1.04 million of assessed value, not a share of the home: an heir of a $3,000,000 house saves the same dollars as an heir of a $1,500,000 house.

Deadlines and forms for an heir

The version of section 63.2(f)(1)(A) we read on the Legislature’s website (through an Internet Archive copy) lists a third trigger, “or an eligible transferee no longer occupies the residence,” whichever is earliest. The BOE’s August 2026 letter states only the three-year and third-party limits. File early and do not wait for the three years.

What ends the break

• Moving out. The exclusion is removed on the date the eligible transferee stops qualifying for the exemption, and the value at inheritance, factored forward for inflation, is enrolled at the next lien date (section 63.2(a)(1)(C)). The Proposition 13 factor is capped at 2 percent a year in the BOE’s explanation. If there are several heirs, one living there is enough: “only a single eligible transferee, from any of the transfers, needs to continuously occupy the home to maintain the exclusion.”
• Renting it or putting it in an LLC. The BOE’s FAQ treats a transfer to a single-member LLC as a transfer to a third party, and section 63.2(e)(8) says “Real property does not include any interest in a legal entity.” An LLC-owned parent’s home does not pass with the exclusion.
• Passing it down again. A grandchild who receives the home from the heir is not a “subsequent eligible transferee”; it is a second transfer that must qualify by itself, and the assessor can apply the step transaction doctrine to a series of transfers.
• Multi-unit property. Only the unit the parent occupied qualifies. If the parent lived in one unit of an apartment building, the rest of the building is reassessed.
• Trusts and life estates. The BOE looks through a trust to the present beneficial owner. For a life estate to a friend with the remainder to children, the claim period “does not begin to run until their interest becomes possessory.” See California probate fees for the court-process side.
• Definition of child. A child adopted by someone else before age 18 no longer counts for the birth parent; an “equitable adoption” does not count either, according to the BOE.

Partial interests work: in the BOE’s example, 41.67 percent of a home with a factored base year value of $163,076 and a market value of $1,200,000 (a transfer before February 16, 2023) leaves the whole home at a new taxable value of $178,462.

Wildfire-area claims and the probate bill

Two changes sit at the edge. SB 293 (Stats. 2025, chapter 539, effective January 1, 2026) treats claims as timely for properties hit by the 2025 Palisades, Eaton, Hurst, Lidia, Sunset or Woodley fires if filed within three years of an assessor’s notice, for claims filed before January 1, 2031. The BOE adds that the bill “did not extend the one-year occupancy deadline.”

SB 288 would start the one-year clock from a probate court order instead of the date of death. The BOE’s analysis of the January 22, 2026 version says the probate process “generally takes 9 to 18 months,” which is longer than the one-year window, and estimates the cost at $24 million a year. We could not confirm on October 22, 2026 that SB 288 became law, and the BOE’s August 3, 2026 letter still says the one-year rule has no exceptions. Treat the one-year rule as live.

When the two rules meet

An heir who later turns 55 can use the move rule. The BOE says a person who got the exclusion for an inherited home can sell it and transfer the taxable value if the heir lived there: “Yes, as long as you occupy the inherited residence as a principal place of residence.” The value that travels is the new taxable value from the inheritance, factored, so in our $1,500,000 example the heir carries $455,414 plus inflation, not $300,000. The reverse does not work: if a parent sells to a child and the child takes the exclusion, “the base year value may not be transferred to a replacement dwelling.” Federal consequences of the same house (basis, gain) are on our pages about step-up in basis for inherited real estate and the home sale exclusion; California’s own tax on a rental sale is in California capital gains on rental sales; the age-65 relief that other states give is compared in senior property tax relief by state.

What we cannot tell you about February 2027

The cap resets on February 16, 2027. BOE took 2.15 percent as the FHFA change in California’s house price index for 2024, but the FHFA fourth-quarter 2024 report we saved shows 4.51 percent for California in its purchase-only state table, so BOE’s input is a different series or table that we cannot identify. The same table for 2025 shows California at -0.83 percent, rank 45 among states, against 1.82 percent for the United States. We therefore do not project the 2027 amount. Whether a negative figure lowers the cap is a question for the BOE’s February 2027 letter.

What a reader can do with this

Three decisions carry real money. First, a 55+ owner choosing between buying first and selling first: the 100, 105 and 110 percent lines, the overlap year at full tax, and the two-year wall decide the new taxable value. Second, a family deciding who inherits and who lives in the parent’s home: one heir must move in within one year, and the exemption claim has the same deadline. Third, a family with a rental or second home in California: Proposition 19 does not protect it, so the next owner starts at market value. If a sale, an inheritance or a rental sits behind these choices, it is worth modelling before signing, because several deadlines are fixed in the Constitution and cannot be extended. If the replacement home costs more than the old one, the difference is added to the transferred taxable value.

This is analysis of public documents, not investment, legal or tax advice. The BOE itself writes that its summaries are not a legal interpretation; confirm with the county assessor where the property is.
