Proposition 19 and Your Inherited California Home (2026)

The short version

• Non-primary-residence inherited properties are reassessed to current market value for property-tax purposes — no more "parent-to-child exclusion" on rentals, second homes, or investment properties
• Primary residences can still pass from parent to child with the old tax basis — but only if the child makes the property their own primary residence within one year, and only on the first $1 million of appreciated value above the parents assessed value

Before Prop 19 vs after

Before (Prop 58)

Parents could pass an unlimited number of properties to children, and children could keep the low property-tax basis indefinitely — whether or not they lived there.

After (Prop 19)

Only the parents primary residence qualifies for transfer of the low basis, and only if the child uses it as their own primary residence.

A real example

Dad bought his Mar Vista home in 1978 for $82,000. In 2026, its worth $1.6M with a Prop 13 assessed value of ~$195,000 (annual property tax ~$2,150).

Scenario A: daughter moves in as her primary residence

Under Prop 19, the new assessed value is $195,000 + ($1.6M − $195,000 − $1,000,000) = $600,000. New annual property tax: ~$6,600. Still a big win vs being reassessed to full $1.6M market value.

Scenario B: daughter keeps it as a rental or second home

Reassessed to $1.6M. New annual property tax: ~$17,600. Thats a $15,450/year swing vs the old rules. For a property with those carrying costs, hold-vs-sell math shifts dramatically.

What this means for heirs

• If you were planning to rent out an inherited property: model carrying costs at the full reassessed rate. In LA, that often pushes properties into negative cash flow
• If multiple siblings inherit and no one moves in: you are going to pay the full reassessment. Coordinate on a sale sooner rather than later
• If you have 12 months and want to establish primary residence to preserve the tax basis, make the move permanent — the clock starts at parents date of death

Common Prop 19 mistakes we see

• Filing the wrong form — you need Form BOE-58-AH (Claim for Reassessment Exclusion for Transfer Between Parent and Child), filed with the LA County Assessor within 3 years of the transfer
• Treating a rental as a primary residence on paper — the Assessor cross-references utility bills, voter registration, and DMV records
• Assuming siblings who do not move in also get the exclusion — only the heir who makes it their primary residence qualifies

Sell vs hold decision framework

Ask these five questions:

• Will any heir make this their primary residence within 12 months?
• If yes, how does the $1M cap apply given the propertys current value?
• If held as a rental, what are carrying costs at the reassessed tax rate? Does rent cover it?
• What would a cash sale or retail sale net today, after debts?
• Given your familys situation, does speed/certainty matter more than maximum price?

For most LA heirs we work with, the answer is: sell. The reassessed carrying costs are steep and the market is historically favorable.
