Key Takeaways

• Proposition 19 sharply limited the old parent-child exclusion that let children inherit a parent’s low property-tax basis.
• Now the exclusion generally applies only to a family home the child makes their own primary residence — and even then, only up to a value cap.
• Inherited rentals, vacation homes, and other property are now generally reassessed to current market value, raising the property tax.
• The exclusion cap is adjusted over time; as of this writing it’s the parent’s factored base year value plus about $1,044,586.
• This is a property-tax matter with strict filing requirements — a question for a CPA or the county assessor alongside legal advice.

What Proposition 19 Changed

For decades, California children could inherit their parents’ real estate and their parents’ low Proposition 13 property-tax assessment — often a fraction of the property’s market value. A child could inherit a long-held family home, or a rental, and keep paying property tax based on what the parents paid decades ago. Proposition 19, effective in 2021, dramatically narrowed that benefit.

Under Prop 19, the ability to inherit a parent’s low property-tax basis is now limited in two big ways: it generally applies only to a family home (or family farm) that the child uses as their own primary residence, and even then only up to a value cap. Inherited property that doesn’t meet those conditions — most rentals, vacation homes, and investment property — is generally reassessed to current market value, which can mean a steep property-tax increase.

For families counting on passing down property with its low tax bill intact, this was a major change, and it reshapes the calculus of inheriting California real estate. (Note this is about property tax — a separate issue from the capital gains step-up in basis.)

The Family-Home Exclusion and Its Conditions

The surviving benefit under Prop 19 is the parent-child exclusion for a family home, and it comes with conditions that must all be met:

• The property must have been the parent’s primary residence (with limited exceptions for a family farm).
• The child must make it their own primary residence — generally moving in and claiming the homeowners’ exemption within a set time (about a year).
• The exclusion is capped. If the home’s value exceeds the parent’s existing assessed value by more than the cap amount, the excess gets added to the assessed value — a partial reassessment.

As of this writing, the cap is the parent’s factored base year value plus approximately $1,044,586. That figure is adjusted on a schedule, so the current number should be confirmed with the county assessor or a tax professional before relying on it. Below the cap, the child can keep something close to the parent’s low assessment on a home they live in; above it, part of the increase comes back onto the tax roll.

The practical effect: the exclusion now rewards a child who moves into the family home and meets the deadlines, and offers nothing for inherited property the child rents out or keeps as a second home.

What Gets Reassessed Now

Under the old rules, a child could inherit a parent’s rental property or vacation home and keep the low tax basis. Under Prop 19, that’s largely gone. Inherited property that isn’t a family home the child occupies as a primary residence is generally reassessed to current market value — meaning the property tax jumps to reflect today’s value, often a dramatic increase for long-held property.

This hits common situations hard:

• A child who inherits a rental property and wants to keep renting it: generally reassessed.
• A child who inherits the family vacation home: generally reassessed.
• A child who inherits the family home but doesn’t move in (keeps their own home, or rents the inherited one): generally reassessed, because the primary-residence condition isn’t met.

For many families, this means inheriting California property now comes with a much larger ongoing property-tax bill than it would have before Prop 19 — a key thing to plan around.

Inheriting a parent’s California property and worried about a property-tax spike? Whether the exclusion applies depends on specific, time-sensitive conditions. Bay Legal can help you understand them, alongside your tax advisor.

The Filing Requirements and Deadlines

The exclusion isn’t automatic — it has to be claimed, and the deadlines matter:

• The child generally must file a claim for the parent-child exclusion (there’s a specific form for it), within the time the rules allow.
• To get the homeowners’ benefit from the date of transfer, the child generally must move in and file for the homeowners’ exemption within about a year.

These are separate filings with separate timing, and missing them can cost the exclusion or its full benefit. Because the requirements are specific and the deadlines real, this is an area where families get tripped up — claiming the exclusion correctly and on time is as important as qualifying for it in the first place.

A Note on the Law’s Status

Proposition 19 has been controversial, and there have been efforts to repeal or change it through the ballot. As of this writing, Prop 19 remains the law — proposed repeal measures have not made it through to change it, so the rules described here are current. But because this is an active area, and because the cap figure adjusts on a schedule, the current status and the current numbers should be confirmed before relying on them. This is doubly true given the tax nature of the topic.

Prop 19’s rules and figures are specific, time-sensitive, and a tax matter. Bay Legal can help with the legal side of inheriting property while you confirm the tax details with a CPA or the assessor.

This Is a Tax and Assessor Matter

Proposition 19 is fundamentally about property tax, administered by county assessors and the state. The firm does not provide tax advice, and the specifics — the current cap, how a particular property is valued, exactly how a partial reassessment is calculated, and the filing mechanics — belong with a CPA, tax professional, or the county assessor. What a probate attorney helps with is the legal side: how the property passes, the transfer itself, and coordinating the estate. The tax analysis runs alongside that, with the right professional.

How This Fits With the Rest of Probate

Prop 19 affects the property tax on inherited real estate, a separate issue from the capital gains step-up in basis (which is income tax). It comes up whenever a family inherits California real estate through probate or a trust, and it’s a major reason families plan ahead with probate-avoidance tools.

Frequently Asked Questions

What did Proposition 19 change about inherited property in California?

It sharply limited the parent-child exclusion. Children can now generally keep a parent’s low property-tax basis only on a family home they make their own primary residence, up to a value cap. Other inherited property — rentals, vacation homes — is generally reassessed to market value.

Can I keep my parent’s low property tax if I inherit their house?

Only if you make it your own primary residence and meet the conditions and deadlines, and even then only up to the value cap. If you rent it out or don’t move in, it’s generally reassessed to current market value.

What is the Proposition 19 exclusion cap?

As of this writing, it’s the parent’s factored base year value plus approximately $1,044,586. The figure is adjusted on a schedule, so confirm the current amount with the county assessor or a tax professional.

Does Proposition 19 apply to rental or vacation property?

Generally the exclusion does not. Inherited property that isn’t a family home the child occupies as a primary residence is generally reassessed to current market value, which can sharply increase the property tax.

Is Proposition 19 still the law in California?

As of this writing, yes. There have been efforts to repeal or change it, but they have not succeeded in altering it, so the current rules apply. Because this is an active area, confirm the current status and figures before relying on them.
