Proposition 19 lets you inherit a parent's low property-tax assessment only if the home was their principal residence and you make it your own principal residence within one year of the transfer. Even then, the protection is capped: the excluded amount is the parent's taxable value plus $1,044,586 for transfers between February 16, 2025 and February 15, 2027. Anything above that is added to your assessed value. Rentals, vacation homes and investment property get no exclusion at all and are reassessed to full market value.
That single paragraph is the whole rule. What follows is what it costs, where families get caught, and how the property-tax question interacts with the decision to keep or sell.
What Changed, and When
Before February 16, 2021, Proposition 58 let a parent transfer a principal residence to a child with no reassessment at all, at any value, whether or not the child ever lived there — plus up to $1 million of assessed value in other property. Families used it to hold rental houses across generations at 1970s tax bases.
Proposition 19 replaced that with a much narrower rule, effective for transfers on or after February 16, 2021:
- The property must have been the parent's principal residence at the time of transfer.
- The child must make it their own principal residence within one year of the transfer, and file for the homeowners' or disabled veterans' exemption within that year.
- The exclusion is capped at the parent's factored base year value plus an inflation-adjusted amount — $1,044,586 for transfers occurring February 16, 2025 through February 15, 2027, per the California State Board of Equalization. The BOE recalculates this every two years from the FHFA House Price Index for California; it was $1,000,000 originally and $1,022,600 for the 2023–2025 window.
- No exclusion exists for non-principal residences. A rental, a second home, or an investment property is reassessed to full current market value on transfer.
The BOE's Proposition 19 page is the authoritative summary, and each county assessor administers the claim.
How the Cap Actually Works
The cap is not "your first $1,044,586 of home value is protected." It is a limit on the gap between the parent's taxable value and current market value.
The arithmetic:
- Start with the parent's factored base year value — their Prop 13 assessed value, not what they paid, not what it is worth.
- Add $1,044,586. That sum is the ceiling.
- If the home's market value at transfer is at or below that ceiling, nothing is added. You keep the parent's assessment.
- If market value exceeds the ceiling, the excess is added to the parent's base value, and that becomes your new assessed value.
| Scenario | Parent's Assessed Value | Market Value at Transfer | Ceiling (Assessed + $1,044,586) | Your New Assessed Value | Approx. Annual Tax at 1.1% |
|---|---|---|---|---|---|
| Inland Empire tract home, you move in | $185,000 | $555,000 | $1,229,586 | $185,000 (fully excluded) | ~$2,035 |
| Statewide median home, you move in | $220,000 | $845,000 | $1,264,586 | $220,000 (fully excluded) | ~$2,420 |
| Bay Area home, you move in, cap exceeded | $310,000 | $2,875,000 | $1,354,586 | $1,830,414 | ~$20,135 |
| Same Bay Area home, you rent it out instead | $310,000 | $2,875,000 | No exclusion available | $2,875,000 | ~$31,625 |
| Parents' rental duplex, any value | $140,000 | $780,000 | No exclusion available | $780,000 | ~$8,580 |
Assessed values in the table are illustrative; the tax rate is shown at a round 1.1%, and actual California rates vary by county and by local bond and assessment districts. Your county assessor's parcel record has the real base year value. California's median sale price is $845,000 as of July 2026 (Houzeo).
The pattern the table shows is the one families miss: for most of California, the cap is not the binding constraint — the move-in requirement is. At a $555,000 or $845,000 market value against a low base, the gap is nowhere near $1,044,586. The exclusion is lost not because the house is too valuable but because nobody moves in.
Where Families Get Caught
The rental that was never a residence. Prop 58 protected up to $1 million of assessed value in non-residential property. Prop 19 protects none. If your parents held rentals expecting the old rule to carry, the reassessment on transfer is full and immediate.
Nobody wants to move. The adult children have their own homes, jobs and school districts. The one-year clock runs anyway. If no child establishes the home as a primary residence and files for the homeowners' exemption within a year, the exclusion is gone and the property is reassessed at market value.
Multiple siblings. Only one sibling needs to occupy the home for the exclusion to apply. Per BOE guidance, if that sibling later moves out and another moves in within one year of the move-out, the exclusion continues. This is more workable than most families assume, but it requires someone to actually live there — not to hold a key.
Missing the filing. The exclusion is not automatic. You file a "Claim for Reassessment Exclusion for Transfer Between Parent and Child" with your county assessor; the exact form varies by county. File within one year of the transfer date.
Assuming Prop 19 is the only tax question. It is not. A separate and usually larger issue is the income-tax basis of the home, which resets to fair market value at the date of death. We cover that in capital gains tax on an inherited house in California.
How the Property-Tax Answer Interacts With Keeping or Selling
The Prop 19 analysis often gets framed as a reason to keep the house. Sometimes it is. It is worth running the number rather than assuming.
Take the Bay Area row above. Moving in caps the assessment at $1,830,414, about $20,135 a year. Renting it out means full reassessment to $2,875,000, about $31,625 a year — roughly $11,500 more, every year, indefinitely, on a property you are not living in. Against that, the step-up in basis at death means selling shortly after inheritance typically triggers little or no capital gains tax.
So the real comparison for a family that does not want to live in the house is: an extra five figures of property tax per year, forever, versus a sale that is largely tax-free right now. That math frequently favours selling, and it is the opposite of the instinct most families arrive with.
The counterweight is straightforward and worth stating: a home held for decades in an appreciating market may still out-earn the carrying cost, and there are reasons to keep a family home that are not financial at all. But the decision should be made against the actual annual number, not against a vague sense that Prop 13 is protecting you when Prop 19 has already ended that protection.
What It Costs to Sell an Inherited California Home
If the family does decide to sell, the commission is the largest single line in the transaction, and it is set as a percentage of a value the family did nothing to create.

| $845,000 (California median, July 2026) | $42,250 | $50,700 | $4,399 | ~$12,500 | $46,301 |
| $1,320,000 (Tri-Valley / inner Bay Area) | $66,000 | $79,200 | $7,999 | ~$18,400 | $71,201 |
| $2,875,000 (Peninsula family home) | $143,750 | $172,500 | $12,999 | ~$42,500 | $159,501 |

Note the last row against the Prop 19 arithmetic above. On the $2,875,000 Bay Area home, moving in rather than renting saves roughly $11,500 a year in property tax. A 6% commission on the sale is $172,500 — about fifteen years of that annual difference, paid once. The property-tax question is real, but for a family that is going to sell either way, the commission is the larger number by a wide margin.
Frequently Asked Questions
Does Prop 19 apply to a home I inherited before February 16, 2021?
No. Transfers that occurred before that date fall under the old Proposition 58 rules, which had no move-in requirement and no cap on a principal residence. Prop 19 applies to transfers on or after February 16, 2021.
What is the Prop 19 exclusion amount in 2026?
$1,044,586, for transfers occurring February 16, 2025 through February 15, 2027. The Board of Equalization adjusts it every two years using the FHFA House Price Index for California. It was $1,000,000 at passage and $1,022,600 for the prior window.
Do all the siblings have to move in?
No. Only one child needs to occupy the home as a principal residence. Per BOE guidance, if that sibling moves out and another sibling moves in within one year of the move-out date, the exclusion continues.
What happens if nobody moves in within a year?
The exclusion is lost and the county reassesses the property to its full market value at the date of transfer. There is no partial credit for a late move-in.
Does Prop 19 apply to a rental property or a vacation home?
No exclusion is available. Prop 19 covers a principal residence and a family farm only. Any other property transferred parent-to-child is reassessed to full current market value.
Do I have to file something, or is it automatic?
You must file. The form is typically titled "Claim for Reassessment Exclusion for Transfer Between Parent and Child" and is filed with your county assessor; the exact version varies by county. File within one year of the transfer, and apply for the homeowners' exemption in the same window.
Is Prop 19 the same thing as capital gains tax on an inherited home?
No — they are separate taxes with separate rules. Prop 19 governs the annual property-tax assessment. Capital gains is an income tax on the sale, and the basis steps up to fair market value at the date of death, which usually makes a sale shortly after inheritance close to tax-free. See capital gains tax on an inherited house in California.
Does a grandchild qualify?
Prop 19 allows grandparent-to-grandchild transfers under the same principal-residence and cap rules, but generally only where the grandchild's parents — the middle generation — are deceased.
Where to Start
Pull the parcel record from your county assessor and find the factored base year value. That single number, plus $1,044,586, tells you whether the cap is even in play for your family. For most California homes it is not, and the decision turns entirely on whether anyone will actually live in the house.
If the family is weighing a sale, run the number on the LOQOL savings calculator and check the pricing tiers.
