Proposition 19 lets a parent transfer a primary residence to a child without a full property tax reassessment, but only if the child moves in as their own primary residence within one year and the home’s value doesn’t exceed the parent’s assessed value by more than a set cap — currently $1,044,586. Miss either condition, and the county reassesses the property at current market value.

Quick Answer

Since February 2021, Proposition 19 replaced California’s older, broader parent-child exclusion with a narrower one. A child can inherit a parent’s home at the parent’s lower assessed value only if they occupy it as their primary residence, and only up to a specific value cap adjusted every two years. Rental and vacation properties no longer qualify at all.

Why This Matters for Estate Planning, Not Just Real Estate

Property tax reassessment isn’t a separate issue from estate planning — it’s baked into how a trust is drafted and how a home eventually passes to the next generation. Many California homeowners have owned their property for decades, meaning their assessed value under Proposition 13 is far below current market value. When that gap is large, the difference between qualifying and not qualifying for Proposition 19’s exclusion can mean thousands of dollars a year in additional property tax for the child who inherits the home.

This is why property tax reassessment planning is generally handled alongside — not separately from — a family’s living trust. The trust’s distribution language determines who receives the home and under what conditions, and that language directly affects whether the exclusion is even available when the transfer happens.

What Proposition 19 Changed

Before February 16, 2021, California’s Proposition 58 allowed a parent to transfer a primary residence to a child of any value, plus up to $1 million of assessed value in other property such as rental homes or vacation properties, without reassessment. Proposition 19 narrowed this substantially:

The exclusion now applies only to a property that was the parent’s principal residence and becomes the child’s principal residence.
The child must move in and file for the homeowners’ exemption, generally within one year of the transfer.
Rental property, vacation homes, and commercial property no longer qualify for any parent-child exclusion.
A value cap now limits how much of the gap between assessed value and market value is excluded.

How the Parent-Child Exclusion Works Under Prop 19

To claim the exclusion, a few conditions generally have to be met at the same time: the property was the transferor’s principal residence, the transferee moves in and makes it their own principal residence within the required window, and the appropriate claim form is filed with the county assessor. Missing any one of these conditions typically means the full exclusion doesn’t apply, even if the family intended for it to.

Because these rules interact directly with how a trust names beneficiaries and structures distributions, working through the details with a firm like Jack Stephens Estate Planning Attorney before a transfer happens — rather than after — gives a family the chance to structure the trust language, timing, and required filings correctly the first time. Amending a distribution after a property has already been reassessed doesn’t undo the tax increase.

The Value Limit: How Much Can You Actually Exclude?

The exclusion isn’t unlimited even when a child meets every other requirement. Under the statute implementing Proposition 19, the excluded amount equals the property’s factored base year value at the time of transfer plus a set dollar cap. The California State Board of Equalization, in its official guidance on Proposition 19, confirms that this cap is adjusted every two years using the Federal Housing Finance Agency’s House Price Index for California, and that any market value above the cap is added to the child’s new assessed value rather than excluded from it.

For transfers occurring between February 16, 2025, and February 15, 2027, that cap is $1,044,586 above the parent’s factored base year value. Here’s how the math generally works:

Example: A parent’s factored base year value is $300,000. The home is now worth $1,200,000 at the time of transfer. The gap is $900,000, which falls under the $1,044,586 cap. The child’s new assessed value stays at the parent’s original $300,000 — no reassessment increase.

If that same home were worth $1,500,000 instead, the gap would be $1,200,000, exceeding the cap by $155,414. That excess amount gets added to the child’s new assessed value, resulting in partial — not full — reassessment.

Before Prop 19 vs. After Prop 19

Feature	Before Feb. 16, 2021 (Prop 58)	After Feb. 16, 2021 (Prop 19)
Primary residence transfer	Excluded regardless of value	Excluded up to base year value + adjusted cap
Rental/vacation property transfer	Up to $1 million excluded	Not eligible for exclusion at all
Child’s occupancy requirement	Not required	Child must move in within 1 year
Cap adjustment	N/A	Adjusted every 2 years for inflation

What Happens If a Family Doesn’t Meet the Requirements?

If a child doesn’t move into the home within the required window, or the property was a rental rather than the parent’s principal residence, the county assessor generally reassesses the property at full current market value as of the transfer date. Depending on how long the family held the property, this can mean an annual property tax bill several times higher than what the parent was paying, since older properties often carry decades of Proposition 13’s capped 2% annual increases baked into a much lower assessed value.

This is one of the more common outcomes families run into when a transfer happens without prior planning — the exclusion existed, but a missed filing deadline, a rental property mistaken for a qualifying residence, or a distribution written before Prop 19 took effect ends up defeating it.

Trust Planning and Prop 19

A living trust doesn’t automatically preserve the parent-child exclusion — the distribution language has to account for it. For families with more than one child, or with a mix of a primary residence and other real property, the trust may need specific provisions addressing which child inherits the home, whether that child intends to occupy it, and how the required filings will actually get made once the transfer occurs.

Jack Stephens has practiced law in San Diego since 1990 and has spoken to continuing-education audiences on estate planning topics, including how property tax reassessment planning fits into a broader trust strategy. For families weighing whether to keep a long-held home in the family or plan around Proposition 19’s narrower exclusion, that kind of trust-drafting experience generally matters more than a generic template.

Frequently Asked Questions

Does Proposition 19 apply to a rental property inherited from a parent? No. Proposition 19 eliminated the parent-child exclusion for rental homes, vacation properties, and commercial property entirely. The exclusion now applies only to a property that was the parent’s principal residence and becomes the child’s principal residence within the required timeframe.

How long does a child have to move into an inherited home to qualify? Generally, the child must move in and file for the homeowners’ exemption within one year of the transfer. Missing this window typically means the property is reassessed at current market value, even if the family intended to use the exclusion.

What is the current Proposition 19 value cap? For transfers between February 16, 2025, and February 15, 2027, the cap is $1,044,586 above the parent’s factored base year value. The California State Board of Equalization adjusts this figure every two years based on California housing price data.

Can grandparents transfer property to grandchildren under this exclusion? Generally, yes, but only if both of the grandchild’s parents (the grandparent’s children) are deceased at the time of transfer. Otherwise, the grandparent-to-grandchild transfer doesn’t qualify for the exclusion.

Does a trust automatically protect a property from reassessment? No. Placing a home in a revocable living trust affects probate, not property tax reassessment on its own. Prop 19’s exclusion depends on who ultimately receives the property, whether they occupy it, and whether the required forms are filed — all of which should be addressed in how the trust is drafted.

Is the property tax exclusion the same as the federal step-up in basis? No. The step-up in basis is a federal income tax rule that resets a beneficiary’s capital gains basis to the property’s value at death and is unrelated to Prop 19. A property can qualify for one, both, or neither depending on the circumstances, so it’s generally worth discussing both separately with an attorney.

What happens if the exclusion amount is exceeded? The amount of value above the cap is added to the child’s new assessed value rather than the entire property being reassessed at full market value. This results in partial reassessment — a higher, but not maximal, increase in property taxes going forward.

TL;DR

Proposition 19 narrowed California’s parent-child property tax exclusion to primary residences only, and only if the child occupies the home within about a year of the transfer.
The current value cap is $1,044,586 above the parent’s factored base year value, adjusted every two years by the California State Board of Equalization.
Rental, vacation, and commercial properties no longer qualify for any parent-child exclusion under current law.
A trust’s distribution language should be drafted with Prop 19’s requirements in mind, since amending it after a transfer already triggered reassessment won’t undo the increase.
