If you’ve recently inherited a home in California, or you’re helping to manage an estate that includes real property, there is a law that could cost your family tens of thousands of dollars in additional property taxes — and 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. In this blog, I’m going to walk you through exactly what Prop 19 says, how it affects your decision to keep, sell, or move into an inherited property, and what deadlines you absolutely cannot miss. This is one of those blogs where I’d encourage you to take notes — because the information matters, and the timing matters even more.
I’m Nancy, and 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 our area, and I’ve sat across the table from a lot of families navigating inherited property — including families who didn’t understand Prop 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, I want to be clear: this blog is for educational purposes only. It is not legal advice, and it is not tax advice. Every estate situation is different, and before you make any decisions about an inherited property, you should speak with a qualified California estate attorney and a CPA. What I can do is give you a clear, plain-language explanation of what Prop 19 says and how it tends to affect the decisions families face — so that when you do sit down with your attorney, you already understand the landscape. Let’s get into it.
What Was There Before: Props 58 and 193
To understand Prop 19, you need to know what it replaced — because the contrast is what makes the change so significant for families. Before Prop 19, California had Proposition 58, passed in 1986, and Proposition 193, passed in 1996. Together, these two measures 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.
Under the old rules, you could inherit your parents’ primary residence and keep their assessed value — no matter how much the property had appreciated — with no limit on the value of the home. And you could also inherit up to one million dollars of assessed value in other real property — rental homes, vacation properties, investment properties — and keep those low tax bases too. This was enormously valuable for California families, because property taxes here are calculated on assessed value, and many parents had owned their homes for 20, 30, or even 40 years, with assessed values far below current market prices.
For example, a parent who bought a home in Sacramento in 1985 for $150,000 might have an assessed value today of $250,000 — with a property tax bill of roughly $2,500 per year. But that same home might be worth $700,000 on the open market today. Under the old rules, a child could inherit that home, keep the $250,000 assessed value, and continue paying roughly $2,500 per year in property taxes — whether they moved in or not. That all changed with Prop 19.
What Prop 19 Changed
Proposition 19 passed in November 2020 and took effect for property transfers occurring on or after February 16, 2021. It dramatically narrowed the parent-child exclusion — the protection that allowed heirs to keep a parent’s low property tax base.
Under Prop 19, the parent-child exclusion for inherited property now applies only to a primary residence — and only if the inheriting child moves into that home and makes it their own primary residence within one year of the transfer. That’s the critical rule: one year, and it must become your primary residence.
If the child moves in within that one year and establishes it as their primary residence, there is still a tax benefit — but it is now limited. The child keeps the parent’s assessed value only if the current market value of the home is within $1 million of the parent’s assessed value. If the market value exceeds the parent’s assessed value by more than $1 million, the assessed value is adjusted upward by the amount of that excess. In practical terms, for most Sacramento area homes, if a child moves in within one year, they’ll keep or come very close to keeping the parent’s tax base. But the unlimited exclusion of the old law is gone.
And here is the part that catches the most families off guard: if the child does not move into the home within one year and establish it as their primary residence, the property is fully reassessed at current market value. Period. No exclusion. No protection. The full market value becomes the new assessed base, and property taxes are recalculated accordingly. For a home that’s appreciated significantly over the decades — which describes the vast majority of Sacramento area homes — this reassessment can mean a property tax bill that is three, four, or five times higher than what the parent was paying.
A Real Dollar Example
Let me make this concrete with a straightforward example, because the numbers tell the story better than anything else.
Let’s say a parent purchased a home in Carmichael in 1990. Their assessed value today — after decades of Proposition 13 capped increases — is $280,000. Their annual property tax bill is roughly $2,800 per year. The home’s current market value is $750,000.
Under the old rules — Prop 58 — a child could inherit this home, rent it out, live elsewhere, and continue paying $2,800 per year in property taxes. Indefinitely. That was legal and common.
Under Prop 19, if that same child inherits the home and does not move in and establish it as their primary residence within one year, the home is reassessed at its full market value of $750,000. The new annual property tax bill is roughly $7,500 per year — an increase of $4,700 per year, every year, going forward.
Over ten years, that difference is $47,000 in additional property taxes. Over twenty years, $94,000. And that’s assuming values don’t continue to rise — which of course they typically do, because assessed values increase each year along with the property’s value up to the reassessed base.
Now multiply that scenario across a family that has multiple inherited properties — say a primary residence plus a rental home — and the financial stakes of understanding Prop 19 become very clear, very quickly.
The One-Year Deadline: What It Really Means
The one-year clock starts on the date of transfer — which in a probate context is typically the date the court order is issued transferring title, or the date the trustee records the deed in a trust scenario. This is not necessarily the date your loved one passed away. In probate cases, there can be many months between the date of death and the date title actually transfers — and that gap matters, because your one-year window doesn’t start until transfer occurs.
Moving in means actually establishing the inherited home as your primary residence — filing a homeowner’s exemption with the county assessor’s office, updating your address on your driver’s license, and genuinely living there. It is not enough to visit frequently or keep belongings there. The county assessor looks for affirmative evidence of primary residency.
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. 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.
How Prop 19 Changes the Sell vs. Keep Decision
Before Prop 19, the calculus for many heirs was straightforward: keep the property, rent it out, enjoy the low property tax base, and benefit from ongoing appreciation. It was a compelling financial strategy, and it was perfectly legal.
Prop 19 has fundamentally changed that calculation for heirs who don’t intend to move into the inherited home. If you’re not going to live there — if your life is established elsewhere, if you have your own home, if moving in isn’t realistic — then the property tax benefit that made keeping the home financially attractive under the old rules is largely gone. You’ll be paying taxes based on current market value, which significantly affects the return profile of holding the property as a rental.
For some families, the math still works — particularly if the property is in a high-appreciation area, if rental income is strong, or if there are other non-financial reasons to hold the property. But the analysis is different now, and it needs to be done with current numbers, not with assumptions based on the old rules.
For heirs who are genuinely considering moving into the inherited home as their primary residence, Prop 19 actually creates a meaningful incentive to do so within that one-year window. If you were already considering it, the tax math now strongly favors making that decision promptly and intentionally.
And for heirs who are simply not in a position to move in — because of geography, their own housing situation, family circumstances, or financial reasons — understanding that the reassessment is coming allows you to plan for it, price a potential sale correctly, and make a decision with full information rather than discovering the new tax bill after the fact.
What to Do First If You've Inherited a California Property
Let me give you a clear, practical sequence for what to do if you’re navigating this right now.
First: find out the parent’s current assessed value on the property. You can look this up on your county assessor’s website — in Sacramento County that’s assessor.saccounty.gov. Knowing the assessed value versus the current market value tells you immediately how significant the Prop 19 reassessment impact would be if you don’t move in.
Second: get clarity on the current market value of the property. A real estate agent who specializes in probate and estate properties — and I am available for exactly this — can give you a no-obligation 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 together, or at minimum separately, before you make any decisions. The interplay between property taxes, capital gains taxes, stepped-up basis, and Prop 19 is complex, and 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 runs regardless of how long probate takes, how complicated the estate is, or how busy your life is. If moving in is an option you want to preserve, start taking steps toward establishing residency as soon as title transfers.
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.
Prop 19 is one of the most consequential changes to California real estate law in decades for families dealing with inherited property. The families who navigate it well are the ones who understand it early — before title transfers, before decisions are made, before deadlines pass. I hope this blog gave you a clear foundation for that understanding.
