Inheriting a House in California: Probate, Prop 19, and Your Options

Inheriting a house sounds like a windfall. In practice, it often arrives as a puzzle wrapped in grief — a property you may not have asked for, tangled in legal procedures, tax questions, and family dynamics, at a moment when you're least equipped to deal with any of it. California adds its own layer of complexity, with rules that have shifted significantly in recent years.

This is a practical map of what you're actually facing when you inherit a home in California, and the choices in front of you once the dust settles. None of it is a substitute for professional advice, but understanding the landscape will help you ask better questions.

First: does the home have to go through probate?

Probate is the court-supervised process of transferring a deceased person's assets. Whether an inherited house must go through it depends largely on how the property was held.

If the home was placed in a properly funded living trust, it generally bypasses probate entirely and passes to the beneficiaries relatively quickly. The same is true for property held in joint tenancy with right of survivorship, which passes automatically to the surviving owner, and for homes with a valid transfer-on-death deed.

If the home was owned solely in the deceased person's name with none of these arrangements, formal probate is often required. In California, full probate typically takes 12 to 18 months and involves statutory fees calculated on the gross value of the estate — fees that can reach the tens of thousands of dollars on a home of significant value. The state has, however, expanded simplified procedures in recent years, including a streamlined court petition for a decedent's primary residence under a set value threshold. Because these thresholds adjust for inflation and the rules carry specific conditions, this is an area where an estate attorney's guidance pays for itself.

The practical point: before you make any decision about the house, find out whether it's in probate, and if so, where it stands. You generally cannot complete a sale until the estate has the legal authority to transfer title.

Second: understand the step-up in basis

Here's a piece of good news that many heirs don't know about. When you inherit property, its cost basis for capital gains purposes is generally "stepped up" to the fair market value on the date of the previous owner's death — not the price they originally paid.

This matters enormously. Imagine a parent bought a home decades ago for $150,000, and it's worth $750,000 when they pass away. If they had sold it during their lifetime, they might have owed capital gains tax on roughly $600,000 of appreciation. But because you inherited it, your basis resets to $750,000. If you sell it soon after for around that value, your taxable gain is minimal — potentially close to zero.

The step-up in basis is a federal income tax rule, and it's one of the strongest arguments for selling an inherited home relatively promptly if you don't intend to keep it. The longer you hold and the more the property appreciates beyond the date-of-death value, the more gain you may eventually owe tax on. (California, notably, has no separate inheritance tax, though other rules can apply.)

Third: Proposition 19 changed the property-tax picture

If you're thinking about keeping the home, you need to understand Proposition 19, which took effect in February 2021 and fundamentally altered how inherited property is taxed in California.

Under the old rules, children could inherit a parent's home and keep the parent's low property-tax base indefinitely, thanks to Proposition 13's assessment protections. Prop 19 largely ended that. Now, to keep the parent's low assessed value, the heir must use the home as their own primary residence and file the correct claim within a strict one-year window — and even then, the exclusion is capped. If the home's market value exceeds the parent's assessed value by more than roughly a million dollars, part of the difference is added back to the tax base.

The consequence is significant. An heir who keeps an inherited home as a rental or a second home — rather than moving into it — will typically see the property reassessed to current market value. For a home a family has owned for decades under Prop 13, that reassessment can multiply the annual property-tax bill several times over. Many heirs discover that a house they hoped to hold as an investment no longer pencils out once the new tax bill arrives.

Weighing your three basic options

Once you understand probate status, the step-up in basis, and the Prop 19 implications, the decision usually comes down to three paths.

Keep it and live in it. This preserves the most favorable property-tax treatment under Prop 19, provided you meet the residency and filing requirements. It makes sense if you actually want the home as your primary residence.

Keep it and rent it. This turns the property into an income asset but generally triggers full reassessment, meaning a much higher property-tax bill. Run the numbers carefully: does the rent still cover the new taxes, insurance, maintenance, and any mortgage after reassessment? Sometimes it does. Often it doesn't.

Sell it. Selling captures the value while the step-up in basis keeps capital gains minimal, and it removes the ongoing burden of taxes, insurance, upkeep, and — in many inherited situations — a house full of a lifetime's belongings that someone has to clear out. For heirs who live elsewhere, don't want to become landlords, or share the property with siblings who disagree about its future, selling is frequently the cleanest resolution.

The complications heirs actually face

The textbook options rarely arrive cleanly. Inherited homes often come with deferred maintenance, because the previous owner may have been elderly or ill for years. They may be full of possessions that are emotionally difficult and physically exhausting to sort through. Multiple siblings may inherit shares and disagree about what to do, sometimes requiring a buyout or, in the worst cases, a court-ordered partition. And the property keeps costing money — taxes, insurance, utilities — the entire time the estate is being settled.

These realities are why many families in this position look for the simplest exit rather than the theoretically most lucrative one. A cash sale of the property as-is, for example, avoids the need to repair or even clear out the home before selling — the buyer takes it in its current condition. For families selling an inherited house in California while also grappling with probate timelines and out-of-state logistics, that kind of simplicity can matter more than squeezing out the highest possible price.

The bottom line

An inherited California home brings together three separate puzzles — the legal (probate), the income-tax (step-up in basis), and the property-tax (Prop 19) — and the right decision depends on how all three interact with your own life. The heirs who navigate it best are the ones who get clear on probate status early, understand that the step-up in basis rewards a timely sale, and run honest numbers on what keeping the home would actually cost under current tax rules.

Above all, don't rush into any transfer or sale without professional input. The dollars at stake are large enough, and the rules specific enough, that a conversation with an estate attorney and a tax advisor is money well spent.
