If you’ve inherited a house from a parent in California, you’ve probably heard someone mention “Prop 19,” usually followed by a warning about property taxes. It’s one of the most important (and most confusing) rules for California heirs.

We’ve bought more than 100 inherited homes in California, and Prop 19 comes up in almost every conversation with families. We’re not tax advisors or attorneys, so please confirm the details for your situation with a professional and your county assessor. But here’s a plain-English explanation of what changed and what it means for you.

The Short Version

Before Prop 19, California parents could usually pass their home (and other property) to their children without the property tax being reassessed. The kids kept the parents’ low tax bill, even if they rented the house out.

Prop 19 took effect February 16, 2021, and narrowed that benefit a lot. Today, an inherited home generally keeps the parents’ low property tax base only if:

1. It was the parent’s primary residence, and
2. The child moves in and makes it their own primary residence (generally within one year), and
3. The home’s value is under a set limit, or else part of the value is reassessed.

If the child doesn’t move in, for example if they plan to rent it or keep it as a second home, the property is generally reassessed to current market value, which can raise the property tax bill dramatically.

The official source is the California State Board of Equalization’s Proposition 19 fact sheet.

Why This Matters So Much in California

Under Prop 13, California property taxes are based on a home’s purchase price (its “base year value”), with only small yearly increases. If your parents bought their home decades ago, their tax bill may be a small fraction of what a new buyer would pay today.

For example (a simple illustration, not a tax estimate): a house bought for $150,000 in the 1980s might have a taxable value of a few hundred thousand dollars today, while its market value in the Bay Area could be well over $1 million. Losing the parents’ tax base can mean property taxes several times higher than what your parents paid.

How the Parent-to-Child Exclusion Works Now

It has to be the family home

Prop 19’s parent-child exclusion applies to a family home (the parent’s principal residence) and to family farms. Other properties, like rentals, vacation homes, and commercial buildings, generally get reassessed when they pass to the children.

The child has to live there

The child (or children) who inherits must make it their principal residence, generally within one year, and file for the homeowners’ exemption. If several siblings inherit and one moves in, rules get more complicated. Ask your assessor or attorney.

There’s a value limit

The exclusion only protects up to a certain amount of value. In general, if the home’s market value is more than its current taxable value plus about $1 million (a figure adjusted for inflation every two years), the amount above that limit is added to the taxable value. Your county assessor can tell you the current number.

You have to file

You typically need to file a claim form with your county assessor within a set deadline. Missing the paperwork can cost you the exclusion, so don’t wait.

Grandchildren

Transfers from grandparents to grandchildren can qualify in limited cases, generally when the grandchild’s parent (the grandparent’s child) has passed away.

Prop 19 and Homeowners 55 and Older

Prop 19 also did something positive for some homeowners: people 55 and older, severely disabled homeowners, and victims of wildfires or natural disasters can generally transfer their low property tax base to a replacement home anywhere in California, up to three times, with adjustments if the new home costs more. This is separate from the inheritance rules, but it’s the reason some parents choose to sell and downsize.

What Prop 19 Means for Heirs: Keep, Rent, or Sell?

Here’s how Prop 19 usually plays out for the families we talk to:

• If you’ll move in: You may be able to keep your parents’ low tax base (subject to the value limit). Make sure you file on time.
• If you want to rent it out: Expect the property to be reassessed. Run the numbers on the new tax bill, insurance, repairs, and management before deciding the rental makes sense.
• If no one will live there: Many families decide to sell. Between a higher tax bill, upkeep on an empty house, and siblings who want their share, selling is often the simplest option.

Prop 19 is also one more reason families disagree about what to do with an inherited house. In our experience, the families who do best talk through the numbers together early, before emotions run high.

Prop 19 and Taxes When You Sell

Prop 19 is about property tax, not income tax. If you sell an inherited house, the more important tax rule is usually the “step-up in basis,” which generally resets the home’s cost basis to its value at the date of death and can greatly reduce capital gains tax. We cover that in our article on the tax consequences of selling an inherited house. Always confirm with a tax professional.
