Inheriting a House in California? Mistakes to Avoid (2026)

Inheriting a house in California can be one of the most meaningful — and most expensive — moments a family goes through. The home might be the most valuable asset your parents ever leave you. It’s also the asset California can tie up in court for more than a year. In our tri-county area where Los Angeles, Orange, and San Bernardino counties meet — Brea, Chino Hills, Diamond Bar, Walnut and Yorba Linda — most homes are now worth enough that a few simple mistakes can cost a family tens of thousands of dollars. Here’s how to avoid them.

What happens to a house in California when someone passes away?

When a homeowner passes, their property has to be legally transferred to whoever inherits it. If the home is set up correctly — most often held in a living trust — that transfer happens privately and quickly. If it isn’t, the house usually goes through probate: the court-supervised process for settling an estate.

In California, probate is slow, public, and expensive. It commonly takes 9 to 18 months, sometimes longer, and during that time the family often can’t sell or fully access the home. Anyone can look up what was owned and who inherited it, because probate is part of the public record.

How much does probate really cost in California?

This is the part that surprises most families. California sets probate fees by law, as a percentage of the estate — but the fee is calculated on the gross value of the home, not what you actually owe on it. Your mortgage does not lower the bill. And that statutory fee is paid twice: once to the attorney and once to the person administering the estate.

Here’s what that looks like in real numbers:

• On a home worth about $1,000,000 — a normal home in our area today — the combined statutory fees come to roughly $46,000.
• On a smaller estate around $600,000, it’s still about $21,000.

That’s money that could have gone to the family. Instead, it goes to the process. If you want to understand what a home would actually net your family after costs, our Net Proceeds Analysis can help you see the full picture.

Didn’t a new 2025 law fix probate in California?

Partly — but probably not for you. As of April 1, 2025, a new law known as AB 2016 created a simpler, faster process to transfer a home without full probate. The catch: it only applies when the home is a primary residence worth under $750,000, the whole estate stays under that line, and there is no other real property involved.

Look at our market. In Brea, Chino Hills, Diamond Bar and Walnut, most homes are worth more than $750,000. And if a parent owned even one additional small property, the shortcut is disqualified. So for most families across the San Gabriel Valley and North Orange County, the new law doesn’t help — and you’re right back in full probate. That’s exactly why planning ahead still matters.

Will your children lose the low property taxes? (The Prop 19 trap)

Even if you handle probate, there’s a second issue that blindsides families: property taxes under Proposition 19.

The old rule people remember: parents could pass their home to their children and the kids kept the parents’ low property-tax bill. For many California families, that low tax was the entire reason they could afford to keep the house.

Prop 19 changed that. Now, if you inherit your parents’ home and you do not make it your own primary residence — if you rent it out or keep it as a second home — it gets reassessed to today’s market value, and the property tax can jump dramatically. Even if you do move in, only about $1,000,000 of value above your parents’ old assessed value stays protected, and that number adjusts over time. Above that, you’re reassessed on the difference. Most families never hear about this until the new tax bill arrives — and by then, the options are gone.

Is there any good news under Prop 19 for homeowners 55 and older?

Yes — and it’s a big one. If you’re 55 or older (or severely disabled, or a wildfire/disaster victim), Prop 19 lets you take your low property-tax base with you when you move. You can buy a replacement primary residence anywhere in California and keep that low tax base — up to three times in your lifetime.

So if you’ve been afraid to downsize because you’d lose your low taxes, that fear is outdated. You can move closer to family, get into a home that fits your life now, and bring your low tax bill along. (That’s a whole topic on its own — one we’ll cover in a dedicated guide.)

What mistakes should you avoid when inheriting a house?

Here are the most common — and most expensive — mistakes we see families make, and how to avoid each one:

• Mistake #1 — Assuming a will is enough. A will does not avoid probate in California. A properly funded living trust is the main tool that keeps the home out of court.
• Mistake #2 — Having a trust, but never putting the home into it. This one trips up so many families. A trust only works if the house is formally transferred into it. We’ve seen trusts sitting in a drawer while the home still went through probate. Confirm the title.
• Mistake #3 — Not checking the Prop 19 impact before deciding to keep the home. Whether you move in changes your tax bill dramatically. Know the number before you decide.
• Mistake #4 — Deciding to keep or sell without a plan. Decide early — before an emotional deadline forces a rushed choice — whether you’ll live in it, keep it, or sell it.
• Mistake #5 — Overlooking the stepped-up basis when selling. Families who sell soon after inheriting often benefit from a reset in the home’s value for capital-gains purposes. Ask your CPA — it’s frequently good news.

For the legal documents themselves — the trust, the deeds, the filings — you’ll work with a licensed estate planning attorney. Learn more about how we support families through this process on our Probate Services page.

Should you keep or sell an inherited home?

There’s no single right answer — it depends on your family’s goals and the tax picture. If you sell soon after inheriting, the stepped-up basis can mean little or no capital-gains tax, because the home’s value resets as of the date it was inherited. (Our guide to California capital gains tax on a home sale explains this in more detail.) If you keep the home, you’ll want to weigh the Prop 19 reassessment rules and the ongoing costs. The right move is the one that fits your situation — and it helps to run the numbers before you commit.
