A woman called us last spring about her mother's house in Fremont. Her mom had owned it since 1985, and the property tax bill ran about $3,600 a year. The family assumed it would stay close to that after they inherited it. Then the county sent a new assessment. The bill had jumped to more than $18,000 a year. Nobody had warned them about Prop 19.
That phone call happens a lot now. So let's walk through what Prop 19 actually does, with real numbers, before it surprises your family too.
The short version
Prop 19 changed the rules for inheriting a house in California. If you inherit your parents' home and don't move into it as your own primary residence, the county can reassess it at full market value. On a long-held Bay Area home, that can triple your property tax bill, sometimes more.
If you do move in within one year, you can keep most of the old low tax basis. But the protection is capped at about $1 million of value. Selling the home avoids the ongoing reassessment problem entirely.
This isn't legal or tax advice. Confirm your own situation with your CPA or attorney.
What changed in 2021
Proposition 19 passed in November 2020 and took effect on February 16, 2021. Before that date, the rules were generous. Parents could pass their home to their children with no property-tax reassessment at all, no matter what the home was worth. They could also pass up to $1 million of assessed value on other property the same way.
Plenty of California families counted on that older rule. Mom and Dad bought the house decades ago, the assessed value stayed low under Prop 13, and the kids expected to inherit that low tax basis along with the home.
Prop 19 narrowed all of that. The parent-to-child exclusion still exists, but it's much smaller and comes with conditions.
How the parent-child exclusion works now
To keep your parents' low tax basis on an inherited home, two things have to be true under the current rules.
1. You have to make it your primary residence. The home only qualifies for any exclusion if you move in and claim it as your own primary home. You generally have to file for the homeowners' exemption within one year of the transfer. Miss that window, and the protection can be lost.
2. The protection is capped. Even when you move in, the exclusion only covers so much. If the home's market value at the time you inherit it is more than $1 million above your parents' assessed value, the extra amount gets added to your new assessed value. The $1 million figure adjusts for inflation every couple of years, so the exact number drifts up over time.
One more thing matters here. The exclusion now applies only to a primary residence. A vacation home, a second home, or a rental property no longer qualifies at all. Those get reassessed to full market value the moment they pass to you.
A Bay Area example, in real dollars
Numbers make this clearer than any rule can. Say your parents bought their home in 1985. Under Prop 13, the assessed value crept up slowly and now sits at $300,000. At a local tax rate of roughly 1.2%, their bill is about $3,600 a year.
You inherit the home in 2026. Its market value is now $1,500,000, which is normal for the Bay Area. Here's how the property tax changes depending on what you do.
| Your situation | New assessed value | Approx. property tax per year |
|---|---|---|
| Your parents' old bill | $300,000 | ~$3,600 |
| You move in within 1 year (qualify) | $500,000 | ~$6,000 |
| You don't move in (full reassessment) | $1,500,000 | ~$18,000 |
The middle row is the move-in case. Start with the old assessed value of $300,000, add the $1 million of protected value, and you get $1,300,000. The market value of $1,500,000 is $200,000 above that. So $200,000 gets added to the old assessed value, giving a new assessed value of $500,000. Your tax lands near $6,000 a year.
The bottom row is what happens if you keep the home but don't live in it. The county reassesses to the full $1,500,000, and the bill runs about $18,000 a year. That's five times what your parents paid, every year you own it.
What if I don't move in?
This is the part that catches families off guard. If you inherit the home and rent it out, or just leave it empty, there's no exclusion. The county reassesses it at full market value, and you carry that higher tax bill for as long as you own the property.
The one-year window is the key deadline. You have to move in and file for the homeowners' exemption within a year of the transfer to claim any protection. If your life is set up somewhere else, with your own home, your own job, and your own family, moving into your parents' house just to chase the tax break often isn't realistic.
Your options: keep, rent, or sell
Once you understand the math, the choices get simpler.
Move in and keep it. This is the only path that holds onto most of the old tax basis. It's the right call if you actually want to live in the home and can do it within the one-year window.
Rent it out. Be careful here, because this is where Prop 19 hurts the most. The home gets fully reassessed, so your property tax could jump from $3,600 to $18,000 in our example. If the market rent is $4,500 a month, a big slice of that now goes straight to the county before you touch insurance, repairs, or a mortgage. We're not going to push you to sell a home your family wants to keep. But run the rental numbers with the reassessed tax in them first. Sometimes the math works, and plenty of times it quietly doesn't.
Sell it. Selling ends the reassessment problem. You don't carry a five-figure tax bill on a home you're not living in, and you turn the house into proceeds the family can split or use. You can list it on the open market if it's clean and ready. Or you can sell to a cash buyer like us if the home needs work, the family lives out of the area, or you just want it done without months of showings.
We've bought inherited Bay Area homes since 2009, more than 2,000 homes in all. We pay 100% of the closing costs, we buy as-is, and we can close in 3 to 7 days. Take what matters to you and leave the rest. We handle the cleanout.
What to do now
You have two honest paths, and the right one depends on your family.
- Keep the home if someone will move in within the year and wants to live there. Talk to a CPA about filing the homeowners' exemption on time so you lock in the exclusion.
- Sell the home if no one is moving in and a five-figure tax bill on an empty or rented house doesn't make sense. Get a value from a local agent if it's market-ready, and get a cash offer from us to compare.
Either way, talk to a real person before you decide. Call or text us at 415-800-1415, or fill out the short form below. We'll walk through your numbers in plain English and tell you honestly which path fits.
Frequently asked questions
Does Prop 19 apply if I inherit my parents' home?
Yes. Any transfer of California real estate from a parent to a child after February 16, 2021 falls under Prop 19. The home only keeps its low tax basis if you move in as your primary residence and meet the rules. Otherwise the county reassesses it at market value.
How much is the exclusion?
The parent-child exclusion protects up to about $1 million of value above your parents' assessed value, and only on a primary residence. The $1 million figure adjusts for inflation every couple of years. Any market value beyond that cap gets added to your new assessed value.
Do I have to live in the house?
To claim the exclusion, yes. You have to make the inherited home your own primary residence and file for the homeowners' exemption, generally within one year of the transfer. If you rent it out or leave it empty, there's no exclusion and the home is reassessed at full market value.
Can I avoid Prop 19 reassessment?
The cleanest way to avoid an ongoing reassessment on a home you won't live in is to sell it. Once it's sold, you no longer carry the higher tax bill. Some families also do estate planning ahead of time, so talk to an attorney about your options while your parents are still able to plan.
