If your family bought a home — or built a rental portfolio — in the San Fernando Valley decades ago, what you plan to leave your children could cost them far more in property taxes than you expect. The planning window to address this is open now. It won’t stay that way.
A client came into my Woodland Hills office not long ago — a widower in his late seventies with five rental properties he had accumulated over his lifetime in the Valley. His two daughters planned to keep those properties after he passed. Under the old rules, they would have inherited his low Proposition 13 tax base along with the properties. Under Proposition 19, without planning, they would not.
Here is what the numbers actually looked like:
| Property | Purchased | Purchase price | Value in 2021 | Appreciation |
|---|---|---|---|---|
| Property 1 | 1999 | $175,000 | $1,000,000 | $825,000 |
| Property 2 | 1969 | $21,600 | $835,000 | $813,400 |
| Property 3 | 1977 | $30,000 | $837,000 | $807,000 |
| Property 4 | 1988 | $125,000 | $650,000 | $525,000 |
| Property 5 | 1980 | $60,000 | $670,000 | $610,000 |
| Total portfolio | Total portfolio | $411,600 | $3,992,000 | $3,580,400 |
Before Proposition 19 took effect on October 17, 2021, the parent-child exclusion was broad. Children inheriting property from parents could generally keep the original Proposition 13 tax base, regardless of property value or how the property was used.
Proposition 19 narrowed that exclusion significantly. The new rules work like this:
The inheriting child must move into the home and establish it as their primary residence within one year of the transfer. If they do, a partial exclusion applies — but it is capped. The assessed value can increase by up to $1,000,000 above the prior tax base without triggering full reassessment. When appreciation exceeds that threshold, reassessment applies to the difference.
There is no exclusion under the standard Proposition 19 rules. Properties that the inheriting child does not use as a primary residence are reassessed at current market value at the time of transfer. For the client I described above — with five rental properties his daughters intended to keep — this is precisely the scenario that made planning not just helpful, but essential.

Here is what separates genuine Proposition 19 planning from a surface-level estate plan review: the most effective strategy for families with rental properties or significant real estate portfolios does not rely on the parent-child exclusion at all.
It relies on the fact that when real property is transferred into a business entity — specifically an LLC — an entirely different set of California property tax rules applies.
Under California’s change-in-ownership provisions, what triggers reassessment is a transfer of the property itself. When property is held inside a legal entity, what transfers between generations are ownership interests in that entity — not the property directly. California law only triggers reassessment when a single person or entity acquires more than 50% of the ownership interests in a legal entity that holds property. A properly structured LLC, combined with a coordinated trust, allows a family to transfer interests to children across generations in a way that never crosses that threshold.
For the client with five Valley properties, this approach — implemented correctly and in advance — meant the difference between his daughters inheriting a manageable tax burden and inheriting one that made keeping the properties financially impractical.
“By transferring real estate to a business entity, a completely different set of rules applies to property tax reassessment. Most families — and many attorneys — don’t know this.”
— Richard M. Seff
A trust is essential. But a trust alone does not solve the Proposition 19 problem for families with rental properties or large real estate portfolios. The LLC-plus-trust structure requires coordination, proper drafting, and implementation before a transfer occurs — not after.
If your estate plan was written before October 2021 and includes real property, it is worth a review. Not because something is necessarily wrong — but because the law changed in a way that affects a specific and common planning scenario, and you deserve to know whether what you have in place still accomplishes what you intend.
Proposition 19 affects California property owners broadly, but it falls hardest on a specific group: longtime owners in high-appreciation markets who built their estate plan under the old rules. The San Fernando Valley — Woodland Hills, Calabasas, Tarzana, Encino, West Hills — is one of the most affected regions in Los Angeles County, precisely because property values have appreciated so dramatically over the past forty years.
If you purchased property here decades ago, the gap between your Proposition 13 assessed value and current market value is almost certainly significant. That gap is exactly what Proposition 19 exposes — and what proper planning can protect.
A clear picture of your current property holdings — how they are titled, what the assessed value versus market value gap looks like, and what your children are likely to do with each property.
An honest assessment of whether the parent-child exclusion is meaningful — for your situation, or whether a different planning structure is more appropriate given the numbers.
Where applicable, a coordinated LLC and trust structure — that takes advantage of California’s business entity rules to preserve the low property tax basis across generations.
Integration with your broader estate plan — because Proposition 19 planning does not exist in isolation from your other assets, your Medi-Cal exposure, or your overall goals.
Proper implementation and documentation — including any required filings with the Los Angeles County Assessor’s office to preserve available exclusions where they apply.
A first conversation is straightforward. We review how your property is held, what the numbers mean for your specific situation, and whether your existing plan still does what you think it does. No obligation. Just clarity — while there is still time to act on it.
