Inheriting a House in California Under Prop 19: What Changes and What to Do Next

Under Proposition 19, a child who inherits a parent's California home keeps the parent's low property tax base only if the home was the parent's primary residence and the child makes it their own primary residence within one year. Even then, the protection only goes up to a value cap. Any other inherited property, such as a rental, a vacation home, or a house the child doesn't move into, is reassessed to current market value.

That one rule changes the math for most families. Before Prop 19, most inherited homes kept their old tax base whether or not anyone lived there. Now the choice to keep, rent, or sell comes with a deadline, and the tax bill can look very different depending on what you decide.

What did Prop 19 change about inheriting a house in California?

California voters approved Proposition 19 in November 2020. Its parent-child transfer rules apply to transfers on or after February 16, 2021. It replaced the older Proposition 58 and Proposition 193 rules.

Under the old rules, parents could pass down their primary residence and up to $1 million of assessed value in other property without reassessment. The child didn't have to live in any of it, so an inherited home could become a rental and keep a tax base set decades ago.

Prop 19 narrowed that in three ways:

• Only the family home qualifies. The old exclusion for other property, like rentals, land, and second homes, is gone.
• The child has to live there. The home must become the child's principal residence within one year of the transfer.
• There's a value cap. The exclusion covers the parent's taxable value plus $1 million, and that $1 million figure is adjusted for inflation every two years.

How does the Prop 19 family home exclusion actually work?

Start with the parent's "factored base year value." That's the taxable value on the county roll, which has grown only a small amount each year since the parent bought the home or last had it reassessed.

If the home's current market value is below that taxable value plus the inflation-adjusted $1 million, the child takes over the parent's taxable value. If the market value is above that limit, the amount over the limit gets added to the parent's taxable value. The result is a partial reassessment. It's still well below a full market reassessment, but the bill goes up.

This matters a great deal across Greater Los Angeles. A home bought decades ago in Sherman Oaks, Studio City, or Pasadena can easily have a market value far above its taxable value plus the cap. In much of the Antelope Valley, the gap is often smaller. Either way, it's worth knowing a realistic market value early, and a comparative market analysis is a good place to start.

Who qualifies, and what if a grandchild inherits?

The exclusion applies to transfers from parents to children. That includes stepchildren, adopted children, and sons- and daughters-in-law, with some conditions. Transfers through a living trust count, which is how many Southern California families pass down a home.

Grandchildren can qualify only if every parent of the grandchild who is also the grandparent's child had died by the date of the transfer. The same rules then apply: the home has to be the grandparent's principal residence, the grandchild has to move in within a year, and the value cap still applies.

When several siblings inherit together, or one sibling wants to keep the house and buy out the others, things get more complicated. The way the trust or estate distributes the property can change how the exclusion applies. Have an estate attorney or tax professional review the structure before anyone signs a deed.

What forms and deadlines do heirs need to know?

This is where families most often lose the benefit. The paperwork is straightforward, but it has to be filed. In Los Angeles County, filings go to the Los Angeles County Assessor. Orange County heirs file with the Orange County Assessor.

• Change in Ownership Statement, Death of Real Property Owner (BOE-502-D): generally due within 150 days of the owner's death. If the estate goes through probate, it's due when the probate inventory is filed.
• Claim for parent-child exclusion (BOE-19-P), or BOE-19-G for grandparent-grandchild: file within three years of the transfer, or before the property passes to a third party, whichever comes first. A late claim can still help, but usually only from the filing date forward.
• Homeowners' exemption (or disabled veterans' exemption): the heir moving in must file for it within one year of the transfer. That filing is part of what makes the exclusion stick.

If the child later moves out and the home stops being their principal residence, the exclusion generally ends and the property is reassessed. Moving in to qualify and then turning the home into a rental doesn't keep the old tax base.

Should you keep, rent, or sell an inherited house?

There's no single right answer. In real terms, you're weighing the property tax bill, the condition of the home, your own housing plans, and often the feelings of several family members. Here's how I'd lay out each option for a client.

Keeping it as your home

If you were planning to move anyway and the home fits your life, the family home exclusion can be very valuable. Make sure the one-year move-in window is realistic, and plan for repairs. Older homes often need updates before they're comfortable to live in.

Renting it out

Under Prop 19, a rental is reassessed to market value. Rent has to cover a much larger tax bill along with insurance, maintenance, and vacancy. Before you decide, run the numbers using net operating income, not gross rent. If you're looking at the Antelope Valley, our overview of the rental market for landlords is a useful starting point. If you later sell a rental and want to roll the proceeds into another investment property, a 1031 exchange may be worth discussing with your tax advisor.

Selling it

Many heirs sell, especially when nobody can move in or siblings want their shares in cash. Inherited property often receives a step-up in cost basis for federal income tax purposes, which can reduce capital gains on a sale. A CPA should confirm how that applies to your situation. Before listing, get a clear seller net sheet so every heir can see what they'd actually receive after seller closing costs.

What's the thing most heirs miss?

The timing. Grief and family logistics take time, and the one-year move-in window and the 150-day filing deadline can pass while everyone is still sorting through belongings. Get an early valuation, file the ownership statement, and have an honest family conversation about who wants what. That keeps your options open.

The second thing heirs miss is the condition of the house. A home someone lived in for decades often needs work. Our guide on what to fix before listing and what to skip can help you avoid spending money that won't come back at sale.
