Until February 2021, California parents could pass any property to their children — primary residence of any value, plus up to $1M of other property — and the children kept the parents' low Prop 13 tax base. It was one of the most generous wealth transfer mechanisms in any state. Proposition 19, passed in November 2020 and effective February 16, 2021, narrowed this dramatically. Now, the parent-child exclusion only applies to primary residences, the child must move in within one year, and there's a value cap of $1,044,586 (2025-2027) above the parent's factored base year value.1 For families planning San Diego inheritance under the old rules, the math has fundamentally changed.

What Prop 19 changed

The differences between the old rules (Prop 58, eliminated February 16, 2021) and the new rules (Prop 19) are stark:2

FeaturePre-Feb 2021 (Prop 58)Post-Feb 2021 (Prop 19)
Primary residence transferNo reassessment, any valueExcluded only if child moves in within 1 year, capped value
Rental property transferNo reassessment up to $1M of assessed valueFull reassessment to current market value

The primary residence exclusion: how it works now

Three things must be true for the parent-child exclusion to apply under Prop 19:3

  1. The property must have been the parent's primary residence at the time of transfer (or have qualified for the homeowners' or disabled veterans' exemption).
  2. The child must establish the property as their primary residence within one year of the transfer date. Not "intend to" — actually live there.
  3. The child must file BOE-19-P with the County Assessor within three years of the transfer, and must claim the homeowners' exemption within one year.

The value cap

Even when all three requirements are met, the exclusion is capped:

The math, with numbers

Parents bought a Mira Mesa home in 1992 for $250,000. FBYV in 2026 (after 34 years of ~2% compounding): roughly $490,000. Current market value: $1,050,000.

Now consider parents who bought a La Jolla home in 1985 for $300,000. FBYV in 2026: roughly $675,660. Current market value: $2,800,000.

The cap matters most for high-value coastal San Diego inheritances. For inland, South Bay, and most of the county where median values are $800K-$1.2M, the cap rarely binds — the full FBYV typically transfers if the move-in requirement is met.

The "child must move in" trap

The single most common Prop 19 failure: the child doesn't move in within 1 year. Maybe the child already owns a home elsewhere, has a job in another state, or simply doesn't want to live in the parent's house. The result: full reassessment to current market value. A property that would have cost the family $5,000/year in taxes now costs $30,000/year — often forcing a sale of the family home. Plan this conversation with your children well before any inheritance event. If they don't intend to live there, the property's tax base will be lost regardless of estate planning.

Rental and vacation properties: no exclusion at all

The most dramatic Prop 19 change: rental properties, vacation homes, and any non-primary-residence inherited from parents are now fully reassessed to current market value, with no exclusion available regardless of the child's occupancy.2

Example: parents own a Pacific Beach rental property bought in 1988 for $200,000. FBYV: $424,460. Current market value: $1,400,000. Annual tax under parents: ~$5,009.

When inherited under Prop 19:

For families with rental real estate as a wealth-preservation strategy, this is the harshest part of Prop 19. The strategy that worked under Prop 58 — accumulate California rental properties, pass them to children to keep low tax bases — no longer works.

Strategies that no longer work

The filing process

Three forms matter:3

Missing any of these deadlines can permanently lose the exclusion. The 3-year BOE-19-P deadline is particularly easy to miss because the property tax issue often isn't top-of-mind during the years immediately following a parent's death.

Multiple children, one home

When parents leave a home to multiple siblings, only one needs to move in to preserve the exclusion. Two scenarios:3

Estate planning attorneys typically recommend structuring the inheritance so one child receives the primary residence outright and others receive equivalent value through other assets — preserving both the exclusion and family equity.

The federal estate tax interaction

Federal estate tax and California property tax are different systems with different rules. Two important interactions:

The combination: most families pay no federal estate tax, get a stepped-up basis (no capital gains tax on parent-era appreciation), and — if the child moves in within 1 year — preserve the low Prop 13 base via Prop 19. For these families, careful planning produces the best of all three tax systems.

The repeal initiative

A "Fix Prop 19" repeal initiative began circulating petitions in late 2025 and would, if passed, restore the original Prop 58 inheritance rules.3 Two prior repeal attempts (2022 and 2024) failed to gather enough signatures. For 2026 planning purposes, plan under current law and don't rely on potential repeal.

The honest read

Prop 19 fundamentally changed California inheritance planning, and old advice based on Prop 58 is dangerous. For families with parents owning California real estate, three actions are worth taking now: (1) confirm whether children plan to occupy the primary residence after inheritance — if not, alternative planning is needed; (2) understand that rental and vacation properties will reassess fully and plan accordingly; (3) work with a California estate planning attorney to structure trusts and inheritance documents that maximize whatever protections remain available. The exclusion is narrower than it was — but for families where the math works (primary residence below the cap, child willing to move in), Prop 19 still preserves substantial wealth across generations. Just plan deliberately rather than assuming the old rules still apply.

Prop 19 and California property tax law are complex. Always work with a qualified California estate planning attorney for individual situations. Educational content only — not legal, tax, or financial advice.
