Proposition 19 and the Family Home: Passing California Real Estate to the Next Generation


A property tax basis set decades ago can be worth tens of thousands of dollars a year. Proposition 19 changed the rules for keeping it in the family.
Long-time Bay Area homeowners often pay property taxes based on an assessed value far below what their home would sell for today. Under Proposition 13, assessed values can rise only modestly each year until a change in ownership triggers reassessment to market value. For decades, parents could transfer a home, and up to $1 million of assessed value in other property, to children without reassessment. Proposition 19, approved by voters in November 2020, narrowed that benefit substantially.
What Proposition 19 changed
According to the California State Board of Equalization, for transfers on or after February 16, 2021:
The parent-child (and grandparent-grandchild) exclusion from reassessment now applies only to a family home that was the transferor's principal residence and that the child makes their own principal residence within one year of the transfer. Rental properties, vacation homes, and commercial real estate no longer qualify.
Even for a qualifying family home, the exclusion is capped. The child's new assessed value is the parent's assessed value, unless the market value exceeds that assessed value by more than $1 million (a figure adjusted every two years for inflation), in which case the excess is added to the taxable value.
Family farms receive similar treatment.
Consider a Palo Alto home assessed at $400,000 with a market value of $3.5 million. Under the old rules, a child could inherit it and continue paying tax on $400,000 regardless of how they used it. Under Proposition 19, if the child moves in, the new assessed value is $400,000 plus the amount by which $3.5 million exceeds $1.4 million, or roughly $2.5 million. If the child does not move in, the home is reassessed to full market value.
Base year value transfers for homeowners 55 and older
Proposition 19 also expanded a benefit for older homeowners. Beginning April 1, 2021, homeowners who are 55 or older, severely disabled, or victims of a wildfire or natural disaster may transfer the assessed value of their primary residence to a replacement home anywhere in California, up to three times. If the replacement home costs more than the original, the difference is added to the transferred assessed value. The replacement must be purchased or built within two years of the sale of the original home.
For Silicon Valley empty-nesters who have hesitated to downsize because a new home would carry a much higher tax bill, this provision can make a move more affordable.
Planning considerations
The narrowing of the parent-child exclusion has changed the calculus for many families. Points worth discussing with an attorney include:
Who will live in the home? If no child intends to occupy the property as a principal residence, the reassessment exclusion is unavailable and the property tax step-up should be built into projections.
Trusts and entities. Transfers through a revocable trust are generally treated the same as direct transfers for Proposition 19 purposes. Transfers involving LLCs or other entities have their own change-in-ownership rules and require careful analysis.
Income tax step-up. Inherited real estate generally receives a step-up in income tax basis to fair market value at death, which can eliminate capital gains tax on a sale. This federal and state income tax benefit is separate from, and often larger than, the property tax consideration.
Selling versus keeping. For some families, the combination of reassessment and the income tax step-up argues for selling an inherited home rather than holding it as a rental.
Filing deadlines. The exclusion is not automatic. A claim must be filed with the county assessor, and deadlines apply.
The broader picture
Property tax planning is one piece of an estate plan that also involves the federal estate tax exemption, now $15 million per person for 2026 per Morgan Lewis, income tax basis, and the practical question of what the next generation actually wants. A home that carries deep meaning for parents may be a financial burden for children who live elsewhere.
