How Proposition 19 Changed the Rules for Inheriting a Home in California

If you’ve recently inherited a home in California or you’re helping to manage an estate that includes real property, there’s a law that could cost your family tens of thousands of dollars in additional property taxes. Most people have never heard of it until it’s too late to do anything about it.

It’s called Proposition 19. It went into effect in February of 2021, and it fundamentally changed the rules for inheriting a parent’s home in California.

I specialize in probate, trust, and estate real estate across the Greater Sacramento region. I’ve closed dozens of probate transactions, I work closely with probate attorneys throughout the area, and I’ve sat across the table from families who didn’t fully understand Proposition 19 until after they’d already made decisions that couldn’t be undone. I want to make sure that doesn’t happen to you or your family.

Before I go any further: this is for educational purposes only. It is not legal advice and it is not tax advice. Every estate situation is different. Before you make any decisions about an inherited property, speak with a qualified California estate attorney and a CPA.

What I can give you is a clear, plain-language explanation of what Proposition 19 says and how it tends to affect the decisions families face, so that when you do sit down with your attorney or CPA, you already understand the landscape.

Key takeaways:

The old rules were enormously generous. Before Proposition 19, California had Proposition 58 (passed in 1986) and Proposition 193 (passed in 1996). Together, these allowed children, and in some cases grandchildren, to inherit a parent’s property and keep the parent’s low property tax assessment with very generous limits. You could inherit a primary residence and keep the assessed value regardless of how much the home had appreciated, with no cap on value. You could also inherit up to $1 million of assessed value in other real property, including rentals, vacation homes, and investment properties, and keep those low tax bases too.

Proposition 19 dramatically narrowed the protection. Under the new rules, the parent-child exclusion now applies only to a primary residence, and only if the child moves into that home and makes it their own primary residence within one year of the transfer. If the child moves in within the one-year window, the parent’s assessed value is preserved only if the current market value is within $1 million of the parent’s assessed value. If it exceeds that by more than $1 million, the assessed value is adjusted upward by the excess amount. The unlimited exclusion of the old law is gone.

If the child does not move in within one year, the property is fully reassessed at current market value. Period. No exclusions, no protection. For a home that has appreciated significantly over decades, which describes the vast majority of homes in the Sacramento area, this reassessment can mean a property tax bill that is three, four, or five times higher than what the parent was paying.

The real-dollar impact is staggering. A parent who purchased a home in Carmichael in 1990 might have a current assessed value of $280,000 and a property tax bill of roughly $2,800 per year. That same home might be worth $750,000 on the open market today. Under the old rules, a child could inherit the home, rent it out, live elsewhere, and continue paying $2,800 per year indefinitely. Under Proposition 19, if that child doesn’t move in within one year, the home is reassessed at $750,000 and the new annual tax bill is roughly $7,500. That’s an increase of $4,700 per year. Over 10 years, that’s $47,000 in additional property taxes. Over 20 years, it’s $94,000. And that assumes values don’t continue to rise, which of course they typically do.

The one-year clock starts on the date of transfer, not the date of death. In a probate context, this is typically the date the court order is issued transferring title, or the date the trustee records the deed in a trust scenario. There can be many months between the date of death and the date title actually transfers. That gap matters because your one-year window doesn’t start until the transfer occurs. Moving in means actually establishing the inherited home as your primary residence: filing a homeowner’s exemption with the county assessor, updating your driver’s license, and genuinely living there. The county assessor looks for affirmative evidence of primary residence.

You must also file a claim for the parent-child transfer exclusion with your county assessor within three years of the transfer date, or before the property is sold, whichever comes first. Missing this filing deadline can result in losing the exclusion even if you moved in on time. In Sacramento County, this is filed with the Sacramento County Assessor's Office. In El Dorado County, with the El Dorado County Assessor’s Office. Each county has its own process, and I strongly encourage you to work with your estate attorney to make sure this filing is completed correctly and on time.

What to do first if you’ve inherited a California property:

First, find out the parent’s current assessed value. You can look this up on the county assessor’s website. Knowing the assessed value versus the current market value tells you immediately how significant a Proposition 19 reassessment would be.

Second, get clarity on the current market value. A real estate agent who specializes in probate and estate properties can give you a confidential market analysis. This is not the same as a formal appraisal, but it gives you the information you need to run the financial comparison.

Third, consult a California estate attorney and a CPA before you make any decisions. The interplay between property taxes, capital gains taxes, and stepped-up basis under Proposition 19 is complex. The right decision for your family depends on all of these factors together, not just one of them.

Fourth, if you are seriously considering moving into the property, do not delay. The one-year clock starts ticking regardless of how long probate takes, how complicated the estate is, or how busy your life is.

Fifth, make sure the exclusion claim is filed with your county assessor on time. Your estate attorney should handle this, but confirm it explicitly. This is not a step to assume is being handled. Ask directly.

Proposition 19 is one of the most consequential changes to California real estate law in decades for families dealing with inherited properties. The families who handle it well are the ones who understand it early, before the title transfers, before decisions are made, before deadlines pass.

If you are currently working through an inherited property anywhere in the Greater Sacramento region or El Dorado County, this is exactly the kind of situation I specialize in. I offer a free, confidential consultation where we talk through the property, run a current market analysis, and help you understand all of your options before you make any decisions.
