Are you planning a move to or from Pacifica and worried your property taxes will jump? You are not alone. California’s Prop 19 can help eligible homeowners carry a lower taxable value from one primary home to another, which can make a big difference on the Peninsula. In this guide, you will learn who qualifies, how the math works, what to file, and how to coordinate with escrow and your lender so there are no surprises. Let’s dive in.
Prop 19 basics for Pacifica moves
Prop 19 lets eligible homeowners transfer the taxable value from their current California primary residence to a replacement primary residence anywhere in the state. That includes buyers moving into Pacifica in San Mateo County and sellers leaving Pacifica for another California county.
Key points you should know:
- You can transfer only a California property tax base. Bases from other states do not apply.
- Eligible groups include homeowners age 55 or older, severely disabled homeowners, and those displaced by a declared disaster.
- You can use portability more than once under Prop 19. Confirm the current transfer count and rules with the county assessor before you rely on it.
- Parent-to-child and grandparent-to-grandchild exclusions are narrower under Prop 19 and often do not prevent reassessment unless strict conditions are met.
Who qualifies and what homes qualify
To use Prop 19 portability, you must meet both personal eligibility and property criteria.
- Personal eligibility: You are 55 or older, severely disabled, or you are moving due to a qualifying declared disaster.
- Property type: The original property and the replacement property must be your principal residence. Investment properties and second homes do not qualify.
- Location: Intercounty moves are allowed. You can bring a base year value from any California county to Pacifica, or take a Pacifica base to any other California county.
Timing rules and tax math
Timing matters. Replacement purchases can happen either before you sell the original home or within a set period after the sale. Because exact windows and filing deadlines are critical and can vary by county procedure, contact the San Mateo County Assessor as soon as you plan to use portability.
Here is how the taxable value is generally calculated:
- If the replacement purchase price is equal to or less than the sale price of the original home, you typically keep your original factored base year value.
- If the replacement purchase price is higher than the sale price of the original home, the difference is typically added to your transferred taxable value.
Example to make it clear:
- Your original home’s taxable value: 450,000
- You sell that home for: 1,200,000
- You buy your Pacifica replacement home for: 1,350,000
- Difference between purchase and sale price: 150,000
- New taxable value on the replacement home: 450,000 + 150,000 = 600,000
Your final assessed value depends on the county’s approval of your claim and effective dates, so file early and keep records organized.
How to file your claim in San Mateo County
The reassessment exclusion is not automatic. You need to submit a claim with the county where your replacement home is located. For a Pacifica purchase, that is the San Mateo County Assessor.
Start early with this checklist:
- Confirm eligibility. Age, disability, or disaster displacement, and that both homes are your principal residences.
- Contact the San Mateo County Assessor. Request the Prop 19 claim form and filing instructions.
- Gather documents:
- Recorded deed or closing documents for the sold property
- Purchase contract and closing documents for the replacement property
- Proof of age or disability if applicable
- Recorded deed for the replacement property when available
- Disaster declaration documents if you are claiming that eligibility
- Complete and submit the county claim form with your supporting documents.
- Ask for confirmation. If the claim is pending at closing, request an interim letter or proof of filing.
Tip: Keep copies of all submissions and mailed items. Late or missing filings can lead to a full reassessment at current market value.
Coordinate with escrow and lenders
Tell your escrow officer and lender as soon as you plan to claim portability. Property tax assessments drive tax proration at closing and your new loan’s impound estimates.
What to share and when:
- During escrow: Let both sides know a Prop 19 claim will be filed. Provide the assessor claim number if you have it.
- With your lender: Give written proof of filing and any assessor correspondence so underwriting can use realistic property tax estimates.
- At closing: Expect prorations to use the current year’s bill. The actual reassessed bill may arrive later, and it can differ from prorations.
If your claim is still pending at close, ask the assessor for written confirmation of filing. This can help your lender adjust impounds and prevent payment surprises on your first tax bill.
Common pitfalls to avoid
- Waiting to file. Delays can trigger a full reassessment and higher taxes.
- Mixing up numbers. The portability math uses your sale and purchase prices and your previous taxable value. Do not confuse sale price with assessed value.
- Assuming old parent-to-child rules still apply. Prop 19 narrowed those exclusions. Many transfers that once avoided reassessment no longer do.
- Not looping in escrow and the lender. This can lead to inaccurate impounds and cash flow surprises.
Real-world Pacifica scenarios
- Scenario A: You sell a Pacifica home and buy in another California county. You file the portability claim with that county. Include your Pacifica sale documents and proof of eligibility.
- Scenario B: You buy in Pacifica first, then sell your older California home within the allowed window. You file your claim with San Mateo County after your Pacifica deed records. Ask the assessor what proof of the prior base and sale timing you need.
- Scenario C: You move between California and another state. Portability does not apply. You cannot transfer a non-California base value to Pacifica or take your Pacifica base to another state.
What Prop 19 does not cover
Prop 19 affects property tax assessments only. It does not change federal or state income tax or capital gains tax. If you have questions about capital gains, basis, estate planning, or parent-to-child transfers, consult a qualified tax advisor or attorney.
Your next steps
- Decide if you are eligible based on age, disability, or disaster displacement.
- Map your timing. If you are buying before selling, or selling before buying, call the assessor to align the windows.
- Assemble documents early, then file your claim as soon as you are in contract or close.
- Keep escrow and your lender in the loop with proof of filing.
