Prop 19: Move Anywhere in California and Keep Your Low Property Tax

Plenty of longtime homeowners in Southern California live in a house that no longer fits — too many stairs, too far from the grandkids, too much yard — and stay anyway, because moving would triple the property tax bill. That was true for decades. Since Proposition 19, it isn't. If you're 55 or older, you can sell, buy nearly anywhere in California, and take your low taxable value with you.

Quick Answer

Proposition 19 lets California homeowners who are 55 or older, severely disabled, or displaced by a declared disaster transfer the assessed (taxable) value of their primary home to a replacement primary home anywhere in the state, up to three times, if the replacement is bought or built within two years of the sale. If the new home costs more than the old one sold for, the difference is added to the transferred value.

Why your tax bill is so much lower than your neighbor's

Under Prop 13, a home's taxable value is set when it's bought and then grows a maximum of 2% a year — no matter what the market does. Own a Downey home for 25 years and your taxable value might be $180,000 while the house is worth $750,000. A buyer purchasing it today starts fresh at $750,000 and pays roughly four times your tax. That gap is exactly what used to trap people in place: selling meant giving up the low base. Prop 19 lets qualifying owners carry it along instead.

The math, in plain terms

Two cases cover almost everyone. If your replacement home costs the same or less than what your current home sells for, your old taxable value simply moves with you, unchanged. If the replacement costs more, you add the difference.

  • Sell for $750,000, buy for $650,000, old taxable value $180,000 → new taxable value stays $180,000.
  • Sell for $750,000, buy for $900,000, old taxable value $180,000 → new taxable value is $180,000 + $150,000 = $330,000 — still far below the $900,000 a regular buyer would be taxed on.

At a typical LA-County-area rate of about 1.1%–1.3%, keeping a $180,000 base instead of resetting to $750,000 is roughly $6,500–$7,500 a year in savings — every year you own the new home.

Who qualifies, and the rules that trip people up

Three groups can use the transfer: homeowners 55 or older, severely disabled homeowners, and owners whose home was destroyed in a governor-declared disaster. The details matter:

  • Both homes must be your primary residence — not a rental or vacation home.
  • You must buy or finish building the replacement within two years of selling (before or after the sale).
  • You can use the transfer up to three times in your lifetime (no limit for disaster victims).
  • It works between any two California counties — LA County to Riverside, San Diego, anywhere in the state.
  • You file a claim with the assessor in the county where the NEW home is; it isn't automatic.

The other side of Prop 19: inherited homes

The same law tightened the rules on passing a low tax base to your kids. An inherited home now keeps the parents' low assessed value only if a child moves in and makes it their primary residence — and even then the exclusion is capped. A house the kids keep as a rental gets reassessed at market value. If part of your plan is leaving the home to family, this is worth a conversation with a tax professional before you decide between selling and keeping.

What this looks like in a real move

The sequence most people follow: get a realistic number for what the current home would sell for, shop the replacement with the two-year window in mind, close both, then file the base-transfer claim with the new county's assessor. The timing flexibility helps — you can buy first and sell after, as long as both happen within two years of each other.

Frequently asked questions

Does Prop 19 work if my new home costs more than my old one?

Yes. You don't lose the benefit — the amount your new home costs above your old home's sale price is simply added to your transferred taxable value. You still come out far ahead of starting fresh at the full purchase price.

Can I use Prop 19 to move to another county?

Yes, anywhere in California. Before Prop 19, only a handful of counties accepted incoming transfers. Now every county must.

How many times can I use it?

Up to three times if you qualify by age or disability. Homeowners displaced by a declared disaster aren't subject to the three-time limit.

Do I have to be 55 when I sell, or when I buy?

At least one spouse or co-owner must be 55 or older when the original home sells. If you're close to 55 and planning a move, the timing of the sale can matter — worth checking before you list.

Is the transfer automatic at closing?

No. You must file a claim form with the county assessor where the replacement home is located. File within three years of buying the replacement to get relief back to the purchase date.

Does Prop 19 change anything if I keep my house and leave it to my children?

It can, significantly. A child who inherits and moves in as their primary residence may keep a (capped) low assessed value; a child who keeps it as a rental sees the home reassessed at market value. Talk to a tax or estate professional about your specific situation.
