A lot of Peninsula families are sitting on a version of the same situation: parents bought a home in San Carlos or Belmont decades ago for a fraction of today’s value, and the assessed value has grown slowly under Prop 13 ever since. What happens to that protected tax base when the home passes to the next generation changed dramatically in 2021, and the rules now matter enormously given how much Peninsula values have grown.
What Prop 19 Actually Changed
Before 2021, a parent could pass their home to a child without any reassessment at all, regardless of value, under the old Proposition 58 rules. Prop 19 replaced that with a much narrower exclusion. The home must have been the parent’s principal residence, the child must move in and establish it as their own primary residence within one year, and even then, the exclusion only protects value up to the parent’s factored base year value plus $1,044,586 for 2026. Anything above that cap gets reassessed to current market value.
What This Looks Like With Real Peninsula Numbers
| Scenario | Outcome |
| Parent’s assessed value $400,000; home worth $2.4M; child moves in within a year | Fully protected, since the $2M gap is under the $1,044,586 cap |
| Parent’s assessed value $400,000; home worth $3.2M; child moves in within a year | Partially reassessed, since the $2.8M gap exceeds the cap by roughly $755,000 |
| Child keeps the home as a rental instead of moving in | No exclusion at all; full reassessment to current market value |
Why the Rental Scenario Matters So Much Here
Many Peninsula families have talked about keeping an inherited family home as a rental rather than selling or moving in. Under Prop 19, that choice comes with a real, permanent cost, since rental and investment properties get zero exclusion and are reassessed to full market value the moment title transfers. On a home with decades of appreciation, that can mean a property tax bill many multiples higher than what the parent was paying, every year, indefinitely.
What You Need to Do to Qualify
| Move into the property and establish it as your primary residence within one year of the transfer |
| File for the homeowners’ exemption on the property within that same window |
| File a Claim for Reassessment Exclusion for Transfer Between Parent and Child, form BOE-19-P, with the county assessor |
| At least one eligible child must continue living there as their primary home to keep the exclusion in place |
A Repeal Effort Is Underway, But Plan for Today’s Rules
A signature campaign to repeal the inheritance portions of Prop 19 is currently circulating for the November 2026 ballot, following two earlier attempts that did not qualify. Nothing has changed yet, and it may not. Families should plan around the current rules and update their plan later if the law actually changes, not the other way around.
Frequently Asked Questions
Can I inherit my parents’ Peninsula home and keep the low tax base as a rental?
No. Rental and investment properties receive no exclusion under Prop 19 and are fully reassessed at transfer.
What happens if the home’s value exceeds the exclusion cap?
Only the portion above the parent’s base value plus $1,044,586 gets reassessed; the rest stays protected.
Do I have to live in the home forever to keep the exclusion?
At least one eligible child must continue using it as their primary residence for the exclusion to remain in place.
Does this apply to homes inherited before 2021?
No, Prop 19 only applies to transfers on or after February 16, 2021. Earlier transfers keep their original protections.
