Generally yes if you are 55 or older. Below is the direct answer, the detail behind it, and exactly how to verify it for your specific situation.
Direct Answer
Generally yes if you are 55 or older. Proposition 19 allows qualifying homeowners to sell a primary residence and transfer the low property tax base to a replacement primary residence anywhere in California, up to three times, with an upward adjustment when the replacement home costs more than the one sold. The replacement purchase generally must occur within two years of the sale and the claim must be filed with the county assessor on time, so the deadlines and forms matter as much as the eligibility.
Why this question matters
Thousands of longtime owners stay in homes that no longer fit their lives because they fear losing a property tax bill set decades ago. Prop 19 changed that calculation, and the owners who understand it gain options the rumor mill says they do not have.
The detail behind the answer
The transfer works statewide, ended the old county by county patchwork, and is available up to three times for age eligible owners, plus for persons with severe disabilities and disaster victims under their own rules. When the replacement home costs more than the sale price of the original, the new base is generally your old base plus the price difference, still typically far below a fresh assessment. The same law tightened parent child inheritance transfers: heirs now generally keep a low base only by using the inherited home as their primary residence, within value limits, which changed estate plans built on the old rules.
How to verify
Confirm eligibility, deadlines, and the value adjustment math for your specific scenario with the county assessor, and coordinate the timing with your tax professional.

What I tell clients
For downsizing clients, the Prop 19 transfer is frequently worth more over a retirement than any negotiation point in the sale itself, which is why I model the scenario, sale price, replacement budget, projected new base, before the home ever lists. The sequencing of sell and buy then gets built around protecting the benefit.
Frequently Asked Questions
Can I buy a more expensive replacement home and keep my base?
Yes, with adjustment: your new base is generally your old base plus the difference between the replacement price and the original sale price. The result usually remains far below what a new buyer would be assessed on the same home.
How many times can I use the Prop 19 transfer?
Age eligible homeowners can use the base year transfer up to three times. Transfers for severe disability and disaster loss operate under their own provisions.
What is the deadline to buy the replacement home?
The replacement primary residence generally must be purchased or newly constructed within two years of the sale of the original, with the claim filed with the county assessor within the filing windows. Verify exact deadlines for your case before planning, since late filings can cost the benefit.
Will my kids inherit my low tax base?
Under Prop 19, generally only if a child uses the inherited home as their primary residence, and within value limits. If estate planning is part of your decision, consult an estate planning attorney rather than assuming the pre 2021 rules still apply.
