The duplex is getting reassessed. So is the fourplex, the commercial building, the condo your father rents out in Long Beach, and the cabin nobody lives in.
Prop 19 did not trim the exclusion for investment property. It deleted it, and there is no version of the old rule left to fall back on.
What the change did
Before 2021, a parent could pass up to a million dollars of assessed value in non-residence property to a child with the tax base intact. That was the mechanism that allowed a generation of Los Angeles families to hold small rental buildings across decades. It is gone. Only a family home or a family farm can qualify now, and the family home requires the child to actually live there.
The numbers, since the abstraction hides the damage
Take a real pattern. Your parents bought a Highland Park duplex in 1988. The assessed value today is $180,000. It would sell for $1,400,000. The base property tax rate in California is one percent of assessed value, plus voter-approved local additions, so figure a bit over that in most of Los Angeles County.
| Scenario | Assessed value | Approximate annual tax at about 1.1% |
|---|---|---|
| What your parents pay now | $180,000 | About $2,000 |
| What you pay after inheriting | $1,400,000 | About $15,400 |
| Annual difference | About $13,400 |
Now go look at what the units actually rent for, subtract the new tax number, and see whether the building still works. For a lot of families the honest answer is that a property their parents held comfortably for thirty years does not cash flow for the next generation. That is not a planning failure. It is the design of the law.
There is no clean workaround, and be careful who tells you otherwise
Transferring the building to an LLC does not solve this. Entity ownership has its own change-in-ownership rules, and transfers of entity interests can trigger reassessment on their own terms. Some structures do defer the event, most come with meaningful legal and tax costs, and a few pitched at seminars are aggressive enough that I will not implement them. If someone offers you a guaranteed fix for a few thousand dollars, ask them to put the guarantee in writing.
What people actually do
- Keep it and absorb the new tax, after running the numbers rather than assuming
- Sell it, which at least allows the family to convert an illiquid asset into something divisible among siblings
- Have one child move into a unit of a small multi-unit property, which can qualify that portion as a family home, subject to how the assessor treats mixed use
- Keep it in the parent's hands with a plan for a sale after death, accepting the stepped-up basis and paying the tax during a short holding period
- Restructure ownership during life with real professional advice, understanding the capital gains consequences described below
The trade nobody mentions
Giving the building to your children during your lifetime avoids nothing on the property tax side, since a lifetime transfer is still a change in ownership. Worse, it gives away the step-up in basis that would otherwise apply at death. Your children inherit your original purchase price as their tax basis, and when they eventually sell, the capital gains bill can dwarf the property tax savings you were chasing.
I have seen people trade a $13,000 a year problem for a several hundred thousand dollar one. It happens because property tax feels urgent and capital gains feels theoretical, right up until escrow closes.
Questions we get asked
What about a triplex where my mother lives in one unit?
The unit that was her principal residence can potentially qualify as the family home if you move into it, with the rest reassessed. Assessors apportion this, so ask specifically how your county handles it.
Does it matter that the property has a mortgage?
Not for reassessment. The assessor looks at market value, not equity.
Can I claim the farm exclusion for a large lot?
The family farm category is defined by agricultural use, not by acreage or a few fruit trees. It is narrower than people hope.
If I inherit and sell within a year, do I still owe the higher tax?
You will owe it for the period you hold it, prorated. The buyer is then reassessed at their own purchase price.
Next step
Pull the current assessed value from the county assessor and put it next to a realistic sale price, then calculate the new annual tax at a bit over one percent. If that number breaks the building, the conversation to have with your parents is about selling or restructuring while they are alive. Call (310) 555-0219 for a free 45-minute consultation.
