Prop 19 Planning for Ventura, Santa Barbara, and Los Angeles Counties

Inheriting a parent’s home in California triggers a property tax reassessment to full market value, unless the Proposition 19 parent-child exclusion under Revenue and Taxation Code § 63.2 applies, and that exclusion survives only if you clear two hard conditions: the home was your parent’s principal residence, and you move in and file for the exemption within one year of the transfer. Miss either one, and the county resets the tax bill to what a buyer would pay today.

I work with Ventura County families on this constantly, because most people have heard the words “Prop 19” but not the actual mechanics. Here is what the law requires, what the math looks like on paper, and what your options are while the one-year clock is still running.

The two conditions for the § 63.2 exclusion

Rev. & Tax. Code § 63.2 (the current parent-child exclusion; it replaced the former, now-repealed § 63.1) only protects a transfer that meets both of these:

1. The property was your parent’s principal residence at the time of transfer, not a rental, a vacation home, or investment property.
2. You move into the home and make it your own principal residence within one year of the transfer, and you file for the homeowners’ exemption (or the disabled veterans’ exemption, if it applies) within that same window.

Both conditions have to hold at once. A primary residence you never move into gets reassessed. A rental you do move into does not qualify either, because it was never your parent’s principal residence to begin with.

The rule of thumb I give clients is this: Prop 19 does not tax the inheritance, it reprices the house, and the clock is one year. Nothing about inheriting the property itself is taxed. What changes is the number the county uses to calculate your ongoing property tax bill, and whether you get to keep your parent’s number or start over at market value depends entirely on what you do in the twelve months after the transfer.

Steps to claim the exclusion after the transfer

The exclusion is not automatic. Someone has to affirmatively claim it, on a timeline, with the county assessor. In practice, that means:

1. Confirm the property was your parent’s principal residence at the time of transfer, before you assume the exclusion is even available.
2. Move into the home within one year of the date of transfer and establish it as your own principal residence.
3. File a claim for the homeowners’ exemption (or disabled veterans’ exemption) with the county assessor within that same one-year window, not just move in informally.
4. File the parent-child exclusion claim itself with the assessor so the county applies § 63.2 rather than reassessing by default. Assessors reassess automatically on a change in ownership; the exclusion only applies if you ask for it on time.

How the reassessment math actually works

Even when both conditions are met, you do not simply keep your parent’s old assessed value untouched. You keep that old assessed value plus an inflation-indexed exclusion amount, currently $1,044,586 for transfers occurring February 16, 2025 through February 15, 2027 (adjusted every two years by the California State Board of Equalization). Anything above your parent’s assessed value plus that exclusion gets added on top as new assessed value. Two examples show how differently this can land:

In the first row, the home’s market value ($1,800,000) exceeds the protected amount ($1,444,586) by $355,414, so that excess gets added to the parent’s $400,000 base, landing the child at a new assessed value of $755,414: higher than the parent paid, but far below the $1,800,000 the county would use for a home changing hands on the open market. In the second row, the home’s market value ($1,400,000) never reaches the protected amount ($1,544,586), so there is no excess at all, and the child’s assessed value stays exactly at the parent’s original $500,000. Whether you land in the first scenario or the second depends entirely on the gap between your parent’s assessed value and the home’s current market value. You can run your own numbers with the Prop 19 calculator before you decide what to do with the property.

Rental property and second homes get no protection at all

The § 63.2 exclusion applies only to a home that was your parent’s principal residence. If what you inherit is a rental property, a vacation home, or land held for investment, none of the math above applies. The county reassesses that property to full current market value effective on the date of the transfer, with no base-value carryover and no exclusion amount to offset it. This is one of the biggest changes Prop 19 made: an older version of California law protected up to $1 million of assessed value on non-primary property too, and that protection is gone entirely under current law.

Where this shows up most often in Ventura County families is a paid-off rental unit or a second home near the coast that a parent held for decades. Under the old rules, that property carried a low assessed value forward to the kids, up to the old $1 million cap. Under current law, the reassessment happens on the transfer date regardless of who inherits it or what they plan to do with it, and it happens whether the property passes by will, by trust distribution, or by intestate succession. There is no window to move in later and retroactively claim the exclusion once the property was never the parent’s own residence.

What happens if you miss the one-year window

If you do not move into the home and file for the homeowners’ or disabled veterans’ exemption within one year of the transfer, the exclusion is lost, not delayed. The property is reassessed to full market value as of the transfer date, and there is no second chance to claim the exclusion later by moving in afterward. Families sometimes intend to move in “eventually,” while renting the property out in the meantime or finishing a remodel first. Either of those choices, if they push occupancy past the one-year mark, can cost the exclusion entirely. If more than one sibling inherits the home together, at least one eligible sibling generally needs to move in and file within the year to preserve any exclusion for that ownership share.

The indexed $1 million exclusion, past and current

The exclusion amount is not a fixed $1 million. The California State Board of Equalization adjusts it every two years for inflation, on top of the original statutory base.

The current figure is up 2.15% from the prior period. Expect another adjustment for the period beginning February 16, 2027. See the Board of Equalization’s notice for the current indexed value.

How to plan around Prop 19 before the one-year clock starts

There is no single trick that works for every family, and anyone selling a one-size-fits-all “Prop 19 loophole” should make you nervous. The right approach depends on what you own, who you are leaving it to, and what your family actually wants to do with the property once you are gone.

Depending on your situation, the tools worth evaluating include irrevocable trusts, properly structured LLCs or family partnerships, lifetime transfers, and a deliberate decision about which property your children keep versus which they sell. Each of these carries real trade-offs, including gift tax exposure, loss of control over the asset, and the loss of a stepped-up basis that comes with dying holding the property instead of gifting it during life. Getting one of these wrong can cost more than the reassessment you were trying to avoid, which is the whole reason to work through it with someone before the transfer happens, not after. If a deed transfer is part of the plan, that has to be documented correctly; see property deed transfers for how that fits into the bigger plan. A properly funded living trust is often the vehicle that carries out whichever strategy you choose, but the trust itself does not solve the Prop 19 problem by default. Most existing trusts in Ventura County have never had a Prop 19 review at all.

Not sure whether your current trust already accounts for Prop 19? Start with the free Trust Health Check. I read your trust and tell you whether it needs Prop 19 work, and what the fix would cost.

One detail families often miss: the § 63.2 exclusion runs parent to child. It does not reach grandchildren unless both of the grandchild’s parents (your children) have already died before the transfer. Leaving a home directly to a grandchild whose parent is still living generally means full reassessment, the low tax base does not skip a generation on its own. If keeping a family home in the family across two generations is the goal, that has to be planned for on purpose.

Prop 19 vs. the old rules (Prop 58)

Prop 19 replaced the former parent-child exclusion under Proposition 58, effective February 16, 2021. The change affected both what kind of property qualifies and what the child has to do to keep it.

Filing your Prop 19 claim in Ventura, Santa Barbara, or Los Angeles County

The § 63.2 exclusion is state law, so the two conditions and the indexed exclusion amount are identical everywhere in California. What changes county to county is where the claim goes, where you look up the factored base year value the math depends on, and how much room the exclusion actually gives you, because that depends entirely on the gap between assessed value and market value where the house sits. Ridley Law serves all three counties. The office is in Port Hueneme.

Ventura County

The Ventura County Assessor is at the Government Center, 800 South Victoria Avenue, Ventura, CA 93009-1270, and the office answers at (805) 654-2181. The assessor publishes its family transfer guidance under Tax Savings, and the BOE-19-P claim is filed with that office.

Ventura County has one feature that catches people, and it is the single most important county-specific deadline on this page. The regular assessment appeals window closes September 15. Los Angeles and Santa Barbara Counties both run to November 30. If you inherit in Ventura County and you want to challenge a supplemental assessment through the regular cycle, you have roughly ten fewer weeks than a client one county in either direction. Appeals go to the Clerk of the Board at the same Government Center address, (805) 654-2251.

Countywide single-family median was about $992,500 as of April 2026, per California Association of Realtors data. For a family home a parent bought in Camarillo, Simi Valley, or Thousand Oaks decades ago, the exclusion frequently absorbs the entire gap. For a more recent purchase it often does not.

Santa Barbara County

Claims go to the Santa Barbara County Assessor, part of the Clerk-Recorder-Assessor, at P.O. Box 159, Santa Barbara, CA 93102-0159. Parcel and assessed value lookups run through the assessor’s property search at sbcassessor.com. Note the county’s own caveat on that portal: it has no owner-name search, and the county treats the data as informational rather than authoritative for tax or appeal purposes. Pull the actual value notice before relying on a number.

Santa Barbara County is really two property markets, and Prop 19 lands very differently in each. On the South Coast, house medians ran around $2.1 million in June 2026, with Montecito near $5.6 million in May 2026 and Goleta about $1,847,500. In North County, Lompoc sat near $570,000 in the second quarter of 2026 and Santa Maria near $665,000.

That three to four times spread is not trivia. The exclusion is a fixed dollar amount added to the factored base year value. A Santa Maria transfer will very often come in under the cap and keep the parent’s basis intact. A Montecito or Carpinteria transfer of a long-held family home will very often blow through it, and the family gets a partial increase rather than full protection. Same county, same statute, opposite outcome. Anyone quoting you a single “Santa Barbara County” answer has not asked where the house is.

Appeals go to the Clerk of the Board, 105 East Anapamu Street, Room 407, Santa Barbara, CA 93101, (805) 568-2247. The regular window runs July 2 to November 30.

Los Angeles County

The Los Angeles County Assessor publishes Prop 19 guidance at assessor.lacounty.gov and answers at (213) 974-3211. Assessed values and parcel records are at the assessor portal, portal.assessor.lacounty.gov, searchable by address or by the ten-digit AIN.

This is the largest assessor’s office in California by volume. Plan on the calendar being less forgiving than in Ventura or Santa Barbara, and do not treat a filing as done because it was mailed. Confirm receipt.

Single-family medians ran in the neighborhood of $900,000 across mid-2026, though Los Angeles County is less usefully described by one number than either of its neighbors given the spread between, say, Santa Clarita and the Westside. Appeals go to the Assessment Appeals Board, regular window July 2 to November 30. Supplemental and escape assessment appeals are different: those run 60 days from the mailing date on the notice, which is the deadline most often missed after an inherited-property reassessment.

What is the same in all three

The claim form is BOE-19-P in every California county. All three counties distribute it through the statewide county assessors’ e-forms service. Filing methods do change, so confirm the current accepted method with the assessor before you send anything, rather than assuming what worked last year still works.

The filing deadline is also statewide: within three years of the transfer, or before the property is transferred to a third party, whichever comes first, with an additional grace period of six months from the date of a supplemental or escape assessment notice. File late and the exclusion still applies, but only going forward from the year you filed. The years in between are not recoverable.

County contacts, filing windows, and market figures above verified as of July 25, 2026. Assessor procedures change. Confirm current details with the county before filing.

Prop 19 Planning FAQs

Will I lose my parents’ property tax basis?

Not entirely, if the home was your parent’s principal residence, you move in and make it your own principal residence within one year, and you file for the homeowners’ exemption within that year. You keep your parent’s assessed value plus the current $1,044,586 exclusion; anything above that combined figure gets added to your new assessed value. If the property was a rental or vacation home, or if you miss the one-year window, you lose the old basis entirely and are reassessed at full market value.

What is the Prop 19 $1 million exclusion in 2026?

In 2026, the exclusion amount is $1,044,586, the indexed figure that applies to transfers occurring February 16, 2025 through February 15, 2027. It is not a flat $1 million; the California State Board of Equalization adjusts the statutory $1,000,000 base for inflation every two years, and $1,044,586 is the current adjusted figure.

Do I have to live in the inherited house?

Yes, to keep any part of your parent’s old assessed value. The § 63.2 exclusion requires you to move into the home and make it your own principal residence within one year of the transfer, and file for the applicable exemption in that window. If you plan to rent the home out or use it as a second home instead, the exclusion does not apply at all and the property is reassessed to full market value. The rule of thumb holds either way: Prop 19 does not tax the inheritance, it reprices the house, and the clock is one year.

Prop 19 planning connects directly to the rest of your estate plan, and to the broader shifts covered in 2026 California estate law changes. If you are the child of a Ventura County homeowner and want to know exactly where your family stands before the one-year clock starts, I can walk through the numbers with you.
