The short answer

Yes. If you are 55 or older and sell your primary home anywhere in California, you can buy a replacement home anywhere else in California and carry your existing property tax base with you. California's Proposition 19 allows this up to three times in your life.

  • Who qualifies: homeowners 55+, severely disabled homeowners, and wildfire or natural-disaster victims.

  • Where you can move: any county in California, in either direction. Santa Barbara to Solvang, Los Angeles to Santa Barbara, Montecito to San Luis Obispo, or the Bay Area to Santa Ynez all qualify. The only limit is the state line.

  • Timing: buy the new home within two years before or after selling the old one.

  • Price: the new home can cost more. If it does, only the difference is added to your tax base.

  • How to claim: file form BOE-19-B with the Assessor in the county where the new home sits, within three years of buying it.

This guide uses Santa Barbara and the Santa Ynez Valley as examples, but the rules are the same statewide. On a typical Santa Barbara home owned since the 1990s, this can mean saving $10,000 to $20,000 or more every year in property tax.

Why this matters for California homeowners — and the Central Coast

Many of the longtime homeowners I talk with in Santa Barbara and Montecito are ready for a change. Some want more space, quiet and oak trees in Santa Ynez, Solvang or Los Olivos. Others in the Valley want to be closer to Cottage Hospital, the beach or their grandkids in town. And many buyers 55+ from Los Angeles, Orange County and the Bay Area are moving here to retire.

What stops most of them is not the price of the next house. It is the fear of losing a property tax bill set decades ago under Prop 13. Prop 19 removes most of that fear, wherever in California they are moving from or to.

In Santa Barbara County, the property tax rate runs roughly 1.1% of assessed value. A couple who bought in 1995 may pay $4,000 to $6,000 a year. Buy a $1.8 million home without Prop 19, and that bill could jump to about $20,000. Prop 19 is the tool that closes most of that gap.

As a Seniors Real Estate Specialist (SRES®), this is the conversation I have most often with clients 55 and over. People first, property second: the right move is the one that fits your life and your budget for the next 20 years.

How Prop 19's base year value transfer works

Voters approved Proposition 19 in November 2020, and its base year value transfer took effect April 1, 2021. It replaced the old Prop 60/90 rules, which only allowed one transfer, to an equal-or-cheaper home, mostly within the same county.

Rule

Old law (Prop 60/90)

Prop 19 (current law)

Where the new home can be

Same county, or one of about 10 participating counties

Anywhere in California

Price of the new home

Equal or lesser value only

Any value; excess is added to the tax base

How many times

Once

Up to three times

Timing

Within 2 years of the sale

Within 2 years before or after the sale

Claim form (age 55+)

BOE-60-AH

BOE-19-B

The "equal or lesser value" test

Your old tax base transfers untouched if the new home's market value stays within these limits:

  • 100% of the old home's sale value if you buy the new home before you sell.

  • 105% if you buy within the first year after you sell.

  • 110% if you buy within the second year after you sell.

If you pay more than that, the extra amount is added to your transferred base. You still keep most of the savings.

Key fine print

  • You must be 55 or older on the date the original home sells. For married couples, only one spouse has to be 55.

  • The original home must be your principal residence when it sells (or within two years of buying the replacement).

  • There is no minimum time you must have lived there.

  • Each spouse can use the transfer up to three times, and earlier Prop 60/90 transfers don't count against the three.

  • If you buy first, you pay tax on the new home's full value until the old one sells. There is no refund for that period.

  • Prop 19 changes only the assessed value. Bonds, Mello-Roos and special assessments on the new home still apply.

  • The two-year window cannot be extended for any reason, including hardship.

Local example: Santa Barbara vs. the Santa Ynez Valley

The same math applies to any California move, but here is how it looks locally. Because Santa Barbara, Santa Ynez and Los Olivos sit at similar price points, many moves between them pass the "equal or lesser value" test outright. Solvang usually comes in lower, which makes it a natural downsizing destination.

Community

Typical home value (Sept 2026)

What it means for a Prop 19 move from Santa Barbara

Montecito

about $5.6M

Selling here, almost any Valley home qualifies with no added value

Santa Ynez

about $1.88M

Often a near even trade with Santa Barbara

Santa Barbara

about $1.82M

Recent closings centered near $1.8M

Los Olivos

about $1.76M

Often qualifies at or under 100%

Solvang

about $1.41M

Usually well under the limit — full transfer

These are area-wide figures from Zillow's home value index; your own home's value can be very different. Recent Santa Barbara closings show how wide the range is: the middle half sold between roughly $1.29M and $3.37M over six months ending August 2026 (Resideline). That is why a property-specific CMA, not a median, should drive your Prop 19 plan.

Three local examples, with the math

Each example uses an illustrative 1.1% tax rate and a hypothetical assessed value. Your actual bill will depend on your exact assessed value and local bonds.

Scenario

Sale price of old home

Price of new home

New tax base with Prop 19

Yearly tax with Prop 19

Yearly tax without

Yearly savings

A. Santa Barbara → Solvang (downsize)

$2,000,000

$1,500,000

$450,000

about $4,950

about $16,500

about $11,550

B. Santa Barbara → Santa Ynez (move up, 8 months after sale)

$2,000,000

$2,300,000

$650,000

about $7,150

about $25,300

about $18,150

C. Santa Ynez → Santa Barbara condo (buy first)

$1,900,000

$1,100,000

$380,000

about $4,180

about $12,100

about $7,920

Example A — the Riviera couple heading to Solvang. They bought in the 1990s and their assessed value is now about $450,000. They sell for $2 million and buy a $1.5 million single-level home in Solvang. Because the new home costs less, the full $450,000 base transfers. Over ten years, that is well over $100,000 kept in their pocket.

Example B — moving up to acreage in Santa Ynez. The same couple instead buys a $2.3 million Santa Ynez property eight months after selling. Their limit is 105% of $2 million, or $2.1 million. The $200,000 above that is added to their base: $450,000 + $200,000 = $650,000. They pay more than in Example A, but still save about $18,000 a year.

Example C — Valley to town. A widow in Santa Ynez with a $380,000 assessed value wants to be near family and medical care in Santa Barbara. She buys a $1.1 million condo first, then sells her Valley home for $1.9 million within two years. The condo costs less, so her $380,000 base transfers in full. She pays full-value tax on the condo only for the months between the two closings.

Step by step: how to make a Prop 19 move

  1. Confirm eligibility. Check that you (or your spouse) will be 55 or older on the day your current home closes, and that it is your principal residence.

  2. Look up your current assessed value. It is on your property tax bill or available from your county Assessor (the Santa Barbara County Assessor for homes here). This is the number you'll be carrying with you.

  3. Get a realistic value for your home. A comparative market analysis tells you your "equal or lesser value" ceiling — 100%, 105% or 110% of your sale price.

  4. Decide: buy first or sell first. Buying first means no limbo but a stricter 100% ceiling and full-value tax until you sell. Selling first gives you a 105–110% ceiling but you'll need a place to land.

  5. Shop within your ceiling, or know the cost of going over. Every dollar above the ceiling is added to your tax base at about 1.1% a year.

  6. Close both transactions within two years of each other. This deadline is firm.

  7. Move in, then file. File form BOE-19-B, with proof of age, with the Assessor of the county where the new home is located. It is not done through escrow. File the homeowners' exemption (BOE-266) on the new home too.

  8. File within three years of buying the replacement home. Earlier is better so your first full tax bill reflects the transfer.

Always confirm current forms and procedures with the Assessor in the county where you are buying — for example, the Santa Barbara County Assessor or the California State Board of Equalization.

Six mistakes I see sellers make

  • Assuming the transfer happens automatically. It doesn't. No claim form, no transfer.

  • Missing the two-year window. A delayed sale of the old home, or a slow custom build in the Valley, can push you past the deadline.

  • Comparing list prices instead of market values. The Assessor compares full cash values on the dates of sale and purchase, not asking prices.

  • Forgetting the 100% ceiling when buying first. Buy before you sell and the new home must cost no more than your old home's sale price for a full transfer.

  • Ignoring direct charges. Some newer subdivisions carry bonds or assessments that Prop 19 doesn't reduce.

  • Treating a rental or second home as your "original home." Only your principal residence qualifies. Inherited homes can count if you live in them as your primary residence.

Frequently asked questions

Does Prop 19 only apply in Santa Barbara County?

No. Prop 19 is a statewide California law. You can sell a primary home in any of California's 58 counties and transfer your tax base to a replacement home in any other county. It does not apply to homes outside California.

Can I transfer my Santa Barbara property tax base to a home in Santa Ynez?

Yes. If you are 55 or older, severely disabled, or a disaster victim, Prop 19 lets you transfer your base year value to a replacement primary residence anywhere in California, including Santa Ynez, Solvang, Los Olivos and Buellton.

Can I buy a more expensive home and still use Prop 19?

Yes. The amount above your "equal or lesser value" limit is added to your transferred base. You lose only part of the benefit, not all of it.

Do I have to sell my old home first?

No. You can buy first or sell first, as long as both happen within two years of each other. Buying first lowers your ceiling to 100% of the old home's value.

How many times can I use Prop 19?

Up to three times per person, regardless of any earlier Prop 60/90 transfer.

Where do I file the claim?

With the Assessor of the county where your new home is located, using form BOE-19-B for the age-55 transfer. For a move within Santa Barbara County, that's the Santa Barbara County Assessor.

Can I move from another county into Santa Barbara or Santa Ynez?

Yes. Because Prop 19 works statewide, a buyer 55+ selling in Los Angeles, Orange County, the Bay Area or anywhere else in California can bring their tax base to the Central Coast. Santa Barbara County homeowners can likewise take theirs to any other California county.

Does my child on title disqualify me?

No. If you are one of the buyers and meet the other rules, a co-owner such as an adult child doesn't block the transfer.

Does Prop 19 apply to a vacant lot I plan to build on?

It can. Newly constructed homes qualify, but construction must be complete within two years of selling the original home.
