When the Proposition 19 rules for parent-child transfers took effect in February 2021, my phone rang for weeks. Families wanted to know whether their plan still worked. Some came in. Many said they would call back after the holidays, and a fair number never did.
The law has held steady since then. The misunderstandings have held steady too. These are the five I hear most often from homeowners in Woodland Hills, Tarzana and Encino, and every one of them is expensive.
1. “I have a trust, so Prop 19 is handled”
This is the most common of the common Prop 19 mistakes, and I understand why. A trust does solve a real problem. It keeps your family out of probate.
But probate and property tax reassessment are different questions decided under different bodies of law. Putting your home into a revocable living trust during your lifetime is not a change in ownership and does not trigger reassessment. It also does not answer the Prop 19 question, which is about what happens when the property leaves the trust and goes to your children. Our page on Proposition 19 and trust planning walks through where the line falls.
2. “We bought in 1978, so we’re grandfathered in”
Your Proposition 13 base is protected for as long as you own the property. Nothing about Prop 19 disturbs that, and families are right to feel settled about their own bill.
The confusion is about what happens next. Prop 19 does not govern your ownership. It governs the transfer. A home bought in 1978 and a home bought in 1998 are treated the same way when they pass to a child today, because the date that controls the analysis is the date of the transfer, not the date of the purchase.
3. “My daughter will just move in, so we’re fine”
Moving in is necessary. It is not always sufficient, and there are more moving parts here than most families expect.
The exclusion requires the child to move in within one year and establish the home as their own primary residence. It also requires applying for the Homeowners’ or Disabled Veterans’ Exemption within a year of the transfer, and the occupancy has to continue. A child who moves in, claims the exclusion, and then moves out later can see the property reassessed from that point forward.
Then there is the value limit, which almost nobody knows about. Even when a child does everything correctly, the protected amount is capped at the property’s taxable value at transfer plus an inflation-adjusted figure the State Board of Equalization republishes every two years. For transfers from February 16, 2025 through February 15, 2027 that figure is $1,044,586, with the next adjustment due in February 2027. Market value above the limit gets added to the taxable value.
For a Woodland Hills or Tarzana home carrying a base from the late 1970s and a value well into seven figures, the appreciation often runs past that cap. The daughter moves in, files on time, and still inherits a partially reassessed property.
4. “It’s just the house I need to think about”
The most costly assumption on this list. For rental and investment property, there is no parent-child exclusion at all. None. A rental on the Valley floor that a family has owned since the 1980s is reassessed at current market value when it passes to a child.
Families with one rental are often more exposed than they realize, and families with several face a permanent change to the economics of the whole portfolio. There are coordinated structures involving LLCs and trusts where a different set of California change-in-ownership provisions applies, which an attorney experienced in this area can use to preserve a low Prop 13 basis. They have to be built before any transfer occurs.
5. “We’ll deal with it when the time comes”
This is the one that quietly gets worse every year.
Once the property transfers, whether by death, by inheritance, or by distribution out of a trust, the reassessment question is settled. There is no fixing it afterward. Every strategy that works in this area works because it was put in place while the parent was alive and able to sign.
The families who told me they would call after the holidays when the rules changed are five years older now. Some have since lost the capacity to sign anything. The planning window and the parent’s health are the same window, and it only closes in one direction.
Key Takeaways
- A trust prevents probate. It does not by itself answer the Prop 19 question, which turns on what happens when property leaves the trust.
- A child who moves in must also file for the Homeowners’ or Disabled Veterans’ Exemption within a year and keep living there.
- Even a qualifying transfer is capped. Value above the limit is added to the taxable value.
- Rental property has no parent-child exclusion and is reassessed at full market value.
- Every effective strategy has to be in place before the transfer happens.
Find out whether your plan still does what you think
If your plan was drafted before the Prop 19 rules took effect and you own a home with appreciation above its Prop 13 base, or any rental property, the question is not whether the plan is well written. It is whether it was written under rules that still exist. More on how we approach this on our Proposition 19 planning page.
