Proposition 19 and Your California Home: A Complete Guide (2026)

Proposition 19 passed in November 2020 and took effect February 16, 2021. It changed the rules for inheriting California real estate in ways that most families still don't fully understand, often not until they're already dealing with the consequences.

The short version: your children can no longer automatically inherit your low property tax base. The old rules that let families pass down homes, rentals, and vacation properties at a protected assessed value are largely gone. What remains is a narrow exclusion with strict conditions, and missing any one of them triggers a full reassessment.

This guide covers how Prop 19 actually works, what the exclusion covers, where families run into trouble, and what you can do about it in your estate plan.

What Proposition 19 Changed

To understand Prop 19, you need to know what it replaced.

Under the old rules (Propositions 58 and 193, passed in 1986 and 1996), a parent could transfer their principal residence to a child without any property tax reassessment, regardless of value. They could also transfer up to $1 million in assessed value of other real property, including rental homes and vacation properties, with the same protection. The child did not have to live in the property. This allowed California families to pass real estate from generation to generation while keeping the low property tax base established decades earlier under Proposition 13.

Prop 19 eliminated most of that. Here is what changed:

Rentals and second homes: No exclusion. Full stop. If you leave a rental property or vacation home to your children, it will be reassessed to current market value at your death. No exceptions.

The family home: A limited exclusion still exists, but it comes with two conditions the old law did not require: the child must move in and make it their primary residence within one year, and the exclusion is capped based on value.

The cap: Even when a child moves in, if the home's market value is high enough, there will be a partial reassessment. More on this below.

The Good Old Days of Proposition 13

California property taxes are calculated based on assessed value, not current market value. Proposition 13, passed in 1978, caps annual increases in assessed value at 2% per year as long as there is no change in ownership or new construction.

The result is that a home purchased in 1985 for $150,000 might have an assessed value today of around $350,000, even though it would sell for $1.4 million. The property tax on a $350,000 assessed value, at roughly 1.1% to 1.25% depending on local assessments, is around $4,000 to $4,400 per year. The property tax on a $1.4 million assessed value is around $15,000 to $17,500 per year.

That gap, between what a family has been paying and what they would pay after reassessment, is the financial bombshell that Prop 19 created for inherited property.

The Parent-Child Exclusion: What Still Exists

Prop 19 preserved a limited parent-child exclusion for the family home. It is found in Revenue and Taxation Code Section 63.2. Here are the requirements.

Requirement 1: The property must have been the parent's primary residence

The home being transferred must have been the parent's principal residence at the time of transfer. A rental home, vacation home, or investment property does not qualify, regardless of what the child does with it afterward.

Requirement 2: The child must move in within one year

The child receiving the property must establish it as their primary residence within one year of the date of transfer. Not intend to move in. Not start the process. Actually live there as their primary home within 12 months.

If there are multiple children inheriting the property, only one of them needs to live in it for the exclusion to apply to the entire property. If that child later moves out and another sibling moves in within one year of the move-out date, the exclusion continues.

Requirement 3: File the BOE-19-P with your county assessor

The child must file Claim for Reassessment Exclusion for Transfer Between Parent and Child (Form BOE-19-P) with the county assessor where the property is located. The claim must be filed within three years of the transfer date, or before the property is sold to a third party, whichever comes first. It is also considered timely if filed within six months of receiving the assessor's supplemental or escape assessment notice.

The child must also file for the homeowner's exemption within one year of the transfer. This is what signals to the assessor that the property is the child's primary residence.

Requirement 4: The value must be within the cap

Even when a child meets all of the above requirements, the exclusion is not unlimited. If the home's current market value exceeds the parent's factored base year value plus $1,044,586 (the current inflation-adjusted cap for transfers through February 15, 2027), the excess is added to the child's new assessed value.

Here is how that works in practice:

Example: Parents purchased their El Dorado Hills home in 1990. Their factored base year value (the original purchase price, adjusted for the annual 2% Prop 13 cap) is $320,000. The home is now worth $1.6 million. The child moves in within one year and files the BOE-19-P.

The exclusion covers the factored base year value plus $1,044,586, for a total of $1,364,586. The market value is $1.6 million. The difference is $235,414. That amount gets added to the child's new assessed value.

So the child's new assessed value is $320,000 plus $235,414, which equals $555,414. The property tax on $555,414 at 1.2% is roughly $6,665 per year. That is higher than what the parents were paying, but significantly lower than the $19,200 the child would pay on a full reassessment at $1.6 million.

In Bay Area markets, where homes routinely sell for $2 million or more with assessed values from decades ago, even a qualifying child who moves in will often face a significant reassessment because the gap between assessed value and market value far exceeds the cap.

What Happens When the Exclusion Doesn't Apply

If the child doesn't move in, if the property was a rental, or if the child misses the deadline, the county assessor reassesses the property to current market value as of the date of death.

Here is what that looks like in real numbers:

Roseville home: Market value $950,000. Assessed value $280,000. Annual tax at assessed value: approximately $3,360. Annual tax after reassessment: approximately $11,400. Annual increase: $8,040.

San Jose home: Market value $1.8 million. Assessed value $300,000. Annual tax at assessed value: approximately $3,600. Annual tax after reassessment: approximately $21,600. Annual increase: $18,000.

Rancho Santa Fe home: Market value $4.5 million. Assessed value $450,000. Annual tax at assessed value: approximately $5,400. Annual tax after reassessment: approximately $54,000. Annual increase: $48,600.

These are not edge cases. This is the financial reality for families who inherit California real estate without meeting the Prop 19 exclusion requirements.

Trusts and Proposition 19

A common question: does holding property in a living trust change anything?

No, not for purposes of the Prop 19 exclusion. A revocable living trust is treated as the grantor's property during their lifetime. However, when the parent dies and the property passes to a child through the trust, that is a change in ownership for Prop 19 purposes. The same rules apply: the property must have been the parent's primary residence, the child must move in within one year, and the BOE-19-P must be filed.

What a living trust does do is avoid probate, which is a separate and significant benefit. For more on why that matters in California, see our post on how California probate fees work.

One note on irrevocable trusts: the analysis is more complex. Irrevocable trusts can trigger change in ownership at different points depending on how they are structured. If you have or are considering an irrevocable trust that holds real property, talk to an attorney about the Prop 19 implications before assuming the exclusion applies.

The Senior Portability Benefit

Prop 19 also significantly expanded the property tax portability benefit for homeowners 55 and older. This is one part of the law that works in homeowners' favor.

Under the old rules, homeowners 55 and older could transfer their assessed value to a new home of equal or lesser value, once, within the same county or in one of a limited number of participating counties.

Under Prop 19, homeowners 55 and older can transfer their assessed value to a replacement home anywhere in California, up to three times, with no restriction on the value of the replacement home. If the replacement home costs more than the original, the difference is added to the transferred assessed value.

Example: A homeowner in Pleasanton, age 62, has an assessed value of $400,000 on a home now worth $1.5 million. She sells and buys a home in El Dorado Hills for $900,000. She can transfer her $400,000 assessed value to the new home. Her new property tax is based on $400,000, not $900,000.

The same benefit is available to severely disabled persons of any age and to homeowners who lost their home in a governor-declared disaster.

To use this benefit, the homeowner must complete the sale and purchase of the replacement within two years and file the appropriate claim with the county assessor.

The Repeal Effort

There is currently a third attempt underway to repeal the inheritance portions of Prop 19. The initiative, titled "Fix Prop 19 to Save Our Children's Future," began circulating petitions in late 2025. If proponents gather enough valid signatures by the May 2026 deadline, it could appear on the November 2026 ballot. Two prior repeal efforts in 2022 and 2024 did not qualify.

If it passes, the old Proposition 58 and 193 rules would be reinstated. That would mean children could inherit the family home at any value without reassessment and would also restore the $1 million exclusion for non-primary-residence property.

We will update this post as that effort progresses. For now, plan as if the current Prop 19 rules will continue.

What This Means for Your Estate Plan

Prop 19 does not change whether you need a living trust. It changes what you need your living trust to accomplish and how you should think about transferring real property to your children.

A few things worth discussing with your estate planning attorney:

Your primary residence: If you want your child to keep your home, talk to them now about whether moving in is realistic. If it isn't, consider whether a sale and distribution of cash makes more sense than an inheritance with a large annual property tax increase.

Rental and investment property: There is no exclusion. A child who inherits a rental property will pay property tax based on current market value. In some cases, the increased tax erodes the economic benefit of keeping the property. Plan accordingly.

Multiple heirs: If more than one child inherits the home and only one will live in it, the exclusion still applies, but only that one sibling can claim it. Make sure the trust or will is clear about who receives what and how decisions get made. And for this to work, there needs to be enough other assets to give to the other children.

Filing deadlines: Three years sounds like a long time until it isn't. The BOE-19-P and the homeowner's exemption need to be filed promptly. Successor trustees administering a trust should put these on the checklist immediately.

The cap math: If your home has appreciated significantly, run the numbers. Even if your child moves in, a partial reassessment may still be coming. Understanding the likely tax impact helps your children make an informed decision about whether to keep or sell.

Frequently Asked Questions

Does Prop 19 apply to a home held in a living trust?

Yes. The exclusion rules apply the same way whether the property passes through a trust or directly. The child must still move in within one year and file the BOE-19-P.

What if my child already lives in my home with me?

That helps establish intent, but the child still needs to file the BOE-19-P and the homeowner's exemption within one year of the date of transfer (typically the date of death). Living there before the transfer does not automatically lock in the exclusion.

Can I transfer my home to my child now to avoid Prop 19?

A lifetime gift transfers ownership, which itself triggers a change in ownership and reassessment. In most cases that makes things worse, not better. It also wipes out the income tax step-up in basis your child would receive at your death. This is one of those situations where the estate planning and tax implications need to be analyzed together before doing anything.

What if my child moves in but then moves out two years later?

The exclusion is removed as of the January 1 lien date following the date the child moves out. The new assessed value is the market value of the home on the date the child originally inherited it, adjusted for inflation since then. So the exclusion is not permanent; it applies only as long as the child lives there.

Does Prop 19 affect the step-up in basis?

No. The step-up in basis to fair market value at death is a federal income tax rule and is not affected by Prop 19. Your child's capital gains tax calculation when they eventually sell is a separate analysis from their property tax situation.

What is the current exclusion cap?

For transfers occurring between February 16, 2025, and February 15, 2027, the cap is $1,044,586 above the parent's factored base year value. The California Board of Equalization adjusts this figure every two years for inflation.

Does Prop 19 apply to grandparent-to-grandchild transfers?

Yes, there is a separate grandparent-to-grandchild exclusion under Prop 19, but it only applies if both of the grandchild's parents are deceased. If either parent is living, the transfer is not eligible. The same primary residence and move-in requirements apply.
