Planning a move in Rancho Santa Fe and wondering how Prop 19 might change your property taxes? You are not alone. Many local homeowners are evaluating downsizing, upsizing, or relocating within California and want clarity before they list or write an offer. In this guide, you will learn who can use Prop 19, how base-year value transfers work, what to watch for with inheritance, and the steps to plan your timeline and budget with confidence. Let’s dive in.
Prop 19 at a glance
California voters approved Proposition 19 in 2020. It changed two major areas of property taxes for homeowners:
- Expanded “portability” for eligible homeowners so you may carry your taxable base value to a new primary residence in California, subject to rules.
- Narrowed the parent-to-child and grandparent-to-grandchild property tax exclusion, now generally limited to an inherited home that becomes the heir’s primary residence and meets value and documentation requirements.
Counties implement these rules. For Rancho Santa Fe, the San Diego County Assessor is your primary authority for forms, filing windows, and calculations.
Who qualifies for a base value transfer
You may qualify to transfer your base-year value if you are in one of these categories:
- Age 55 or older.
- Severely and permanently disabled.
- A homeowner whose property was substantially damaged or destroyed in a declared disaster.
Key requirements generally include:
- Your original home was your primary residence at the time of transfer.
- Your replacement home becomes your primary residence.
- You meet county filing deadlines and provide required documentation.
- Prop 19 expanded how often you can transfer. The commonly cited limit is up to three transfers for qualifying homeowners, but you should confirm the exact limit and any exceptions with the San Diego County Assessor.
Quick readiness checklist
- Confirm your eligibility category (age, disability, or disaster).
- Verify both properties qualify as primary residences.
- Ask the assessor about the allowable timing windows for your buy and sell.
- Gather documentation that shows ownership and occupancy.
How base-year value transfers work
The basic idea is simple. You carry your lower assessed value from your original primary residence to your replacement primary residence. This can reduce your ongoing property taxes compared with a full reassessment at today’s market value.
Here is what usually happens with price differences:
- If your replacement home is less expensive than your original property’s market value, you may be able to transfer your original base value as is, subject to county rules.
- If your replacement home is more expensive, the county commonly adds the price difference to your transferred base value to create your new base-year value.
For example, if your original home has a low taxable base and your replacement home is higher in market value, your new tax base would typically be your old base plus the difference between the two market values. The outcome is usually lower than a full reassessment, but higher than your current base. Always ask the San Diego County Assessor for an example calculation specific to your scenario.
Timing you should confirm locally
Prop 19 provides time windows for how long you have to buy or construct a replacement home relative to the sale of your original residence. Some moves involve buying first then selling, while others sell first then buy. The look-back and look-forward timing can vary by situation. Before you close either side of your move, confirm the eligible windows with the San Diego County Assessor.
How to file your claim in San Diego County
- File a base-year value transfer claim with the San Diego County Assessor.
- Provide required documents, such as deeds, closing statements, and evidence that both the original and replacement homes are or will be your primary residence.
- If you are claiming disability eligibility, the county may require certification.
- Keep copies of everything and follow up on the assessor’s determination.
Strategy for common Rancho Santa Fe moves
Rancho Santa Fe is known for high-value homes. If you have a long-held, low assessed value, the ability to transfer that value can materially influence your move plan. Here are common scenarios and how to think about them.
Downsizing in Rancho Santa Fe or nearby
If you are 55 or older and moving to a smaller or lower-priced primary residence, you may be able to transfer your old base value to the new home. This can keep your property taxes below what a full reassessment would produce. Pay close attention to the occupancy and filing requirements, and confirm timing before you list.
Upsizing or moving to a more expensive home
If your replacement home is more expensive, you will likely see your base value adjusted upward by the difference in market values. The transfer can still deliver meaningful savings compared with a full reassessment. Ask the assessor for a side-by-side estimate so you can budget accurately.
Relocating from another California county into Rancho Santa Fe
Prop 19 portability is statewide. If you are eligible, you can move your base value from any California county to your Rancho Santa Fe replacement home. You will file your claim with the San Diego County Assessor after you buy.
Estate planning and inherited property
Prop 19 narrowed the parent-to-child and grandparent-to-grandchild exclusion. Today, an inherited home generally must become the heir’s primary residence to qualify for limited relief, and value thresholds apply. If you expected to transfer a second home or investment property to your heirs without reassessment, you should revisit your estate plan with your advisors.
Budgeting your move with Prop 19
Before you write an offer or list your home, do a quick planning exercise:
- Ask the San Diego County Assessor for an estimate of your new assessed value under Prop 19 and a comparison to a full reassessment at market value.
- Model your likely property tax bill under both scenarios.
- Factor in transaction costs, moving expenses, and any renovation budget for the replacement home.
- Evaluate other taxes and costs that Prop 19 does not change, such as potential capital gains tax and cost of sale.
This kind of side-by-side view helps you determine whether to buy first or sell first, and which price points keep your long-term carrying costs comfortable.
Avoid common pitfalls
- Do not assume the transfer is automatic. You must file a claim with the county.
- Do not miss filing deadlines. Confirm the timing rules for your situation before you close.
- Document your primary residence status. Utility bills, ID, and voter registration can matter.
- Do not overlook the change to inheritance rules. Many prior strategies no longer apply unless strict Prop 19 criteria are met.
- Remember that county calculations are fact-specific. Get guidance directly from the San Diego County Assessor.
