Inherited a home in San Diego? How Prop 19 shapes whether you keep it or sell

Quick answer: Should I keep or sell a home I inherited in San Diego under Prop 19?

In San Diego County, a child keeps a parent's low tax base under Prop 19 only by moving in as their primary residence, and only up to $1,044,586 of added value for transfers from February 2025 to February 2027. Rent it out or leave it empty and it's reassessed to market value, so many heirs weigh selling instead.

Key takeaways

• Prop 19 protects the tax base only if you live in the inherited home.
• The excluded amount is $1,044,586 for transfers through February 15, 2027.
• San Diego County detached homes sold in a median 37 days in September 2026.

If you've just inherited a parent's house, you're probably juggling grief, paperwork, and one big question: do you keep it, rent it, or sell it? Prop 19 changed the math in 2021, and it's the first thing to understand before you decide.

What changed with Prop 19 for inherited homes?

Before February 16, 2021, a parent could pass a home, and often other property, to a child without a property tax reassessment. Prop 19 narrowed that. According to the San Diego County Assessor, the exclusion now covers only the parent's principal residence, and that home has to remain the child's primary residence to keep it.

Rentals, vacation homes, and other property no longer qualify. Those get reassessed to current market value when they transfer.

The exclusion also isn't automatic. You have to file a claim with the Assessor, and the county says the Homeowners' Exemption must be filed within one year of the transfer. If your situation involves a trust or probate, our probate and inherited home page walks through how we help with those sales.

How much of the low tax base can you keep?

The exclusion covers the first $1 million of added value, adjusted every two years. The California State Board of Equalization set it at $1,044,586 for transfers from February 16, 2025, through February 15, 2027 (announced March 7, 2025).

Here's how it works, using my own example (the property values are assumptions, not data): say your parent's taxable value was $300,000, and the home is worth $1,600,000 on the transfer date.

• The cap is $300,000 plus $1,044,586, or $1,344,586.
• The amount over the cap is $1,600,000 minus $1,344,586, or $255,414.
• If you move in, your new taxable value is $300,000 plus $255,414, or $555,414.
• If you don't move in, the taxable value resets to the full $1,600,000.

That gap is why the keep-or-sell decision often comes down to one question: are you going to live there?

Is now a reasonable time to sell an inherited San Diego home?

If you won't live in the home, the numbers are worth a look. In September 2026, San Diego County detached homes had a median sales price of $1,079,000, up 5.8% from a year earlier, according to the Greater San Diego Association of REALTORS® market report (data as of October 5, 2026). Homes sold in a median 37 days and received 97.7% of their original list price.

Buyers are being choosier, though. The California Association of REALTORS® reported San Diego County sales down 12.2% from a year earlier in September 2026 (released October 19, 2026). We covered what slower activity means in our post on the drop in pending sales.

Inherited homes often need updates, so pricing matters even more. A home priced from real comps sells faster than one priced on memories. Our guide on how to tell if a San Diego home is overpriced shows how buyers size up a list price.

What should you do first?

1. Find out how the home transferred. A trust usually moves faster than probate. Ask the estate attorney or trustee where things stand.
2. Decide whether anyone will live there. That answer drives the Prop 19 outcome.
3. File on time. Check the Assessor's deadlines for the exclusion claim and the Homeowners' Exemption.
4. Get a value before you fix anything. Some updates pay off, and some don't. Our post on selling this fall or waiting until spring covers timing.
5. Talk to a CPA. Ask how the cost basis works on inherited property before you sell.

Bottom line

Prop 19 rewards heirs who move in and taxes everyone else at market value. If you won't live in the home, selling in a market where detached homes still trade near list price can be the cleaner path. Start with a real value and a clear plan for the paperwork.
