Moving From the Bay Area to Sacramento Under Prop 19

Yes. If you are 55 or older, severely and permanently disabled, or a disaster victim, you can sell in the Bay Area, buy in the Sacramento region, and take your low Proposition 13 tax base with you. The county line no longer matters, and no county can refuse the transfer.

For most people making this move, the transfer is even better than they expect. Bay Area homes generally sell for more than Sacramento region homes cost. When your replacement home is worth the same or less than the one you sold, your base year value transfers with no adjustment at all. Nothing is added.

You file the claim with the assessor of the county where your new home sits, not the county you left. That one detail sends more people to the wrong office than any other rule in Proposition 19.

Why Trading Down Is the Best Version of This

Proposition 19 compares two market values: what you sold for, and what you bought for.

If the replacement home costs the same or less, your factored base year value moves across intact. Your new tax bill is calculated on your old base, not on what you just paid.

If the replacement home costs more, your new taxable value is your old base plus the difference between the two market values. You still keep most of the benefit.

A Bay Area to Sacramento move usually lands in the first category. Someone selling in San Jose or Oakland and buying in Roseville, Davis or Fairfield is very often buying something larger for less money. That is the cleanest outcome Proposition 19 offers, and it is the reason this particular move is worth planning carefully.

The Timing Cushion When You Buy After Selling

If you sell first and buy second, the comparison is slightly generous to you.

Buy within the first year after selling, and your old home’s sale price is treated as five percent higher for the comparison. Buy in the second year, and it is treated as ten percent higher. That inflated figure is what your purchase price is measured against, so the cushion reduces any amount added to your base.

Buy before you sell and there is no cushion, but the transfer still works. The two-year window runs in both directions.

Which Assessor Gets Your Claim

The claim goes to the county where the replacement home sits. Always.

• Buying in Roseville, Rocklin, Lincoln or Auburn: Placer County
• Buying in El Dorado Hills, Cameron Park or Placerville: El Dorado County
• Buying in Davis, Woodland, West Sacramento or Winters: Yolo County
• Buying in Vacaville, Fairfield, Benicia or Vallejo: Solano County
• Buying in Tracy, Manteca, Lathrop, Mountain House or Stockton: San Joaquin County
• Buying anywhere in the city or county of Sacramento: Sacramento County

Each of those guides carries that county’s address, phone numbers, counter hours, fees and local quirks, and they differ more than you would expect. El Dorado wants original signatures by mail. San Joaquin takes claims online. Yolo closes its counter at 4:00. Solano is working through a system-change backlog.

The Certification Between Two Counties

Your new county has no record of your old assessed value. It has to ask for it.

The county you left issues a base year value certification to the county you moved to. Sacramento County, for example, runs those requests through a dedicated mailbox. Bay Area counties handle it through their assessor’s office.

Start it early. A document traveling between two county bureaucracies is one more thing that can sit in a queue while your three-year filing window runs.

The County That Never Opted In

There is a clean illustration of what Proposition 19 actually changed, and it sits at the edge of this corridor.

Before Proposition 19, the old Propositions 60 and 90 generally confined a base year value transfer to the same county. A county could choose to accept transfers from elsewhere, but most did not, and the list moved around.

San Joaquin County never adopted one of those ordinances. Before April 1, 2021, a homeowner selling in Alameda, Contra Costa or Santa Clara and buying in Tracy or Mountain House could not bring a base year value at all. The county simply did not take them. The commute was popular, the housing was cheaper, and the tax break was unavailable.

Proposition 19 removed that entirely, statewide, and no county can opt out now. If you were told years ago that this move would cost you your tax base, you were told correctly at the time. The rule changed.

What Still Limits You

You have to qualify. Be 55 or older on the date you sell, severely and permanently disabled, or a disaster victim. A move by itself creates no eligibility.

Both homes must be your principal residence. You cannot move a base onto a rental or a second home.

The two-year window governs. Buy and sell within two years of each other.

Three lifetime transfers. Age-55 and disabled claimants get three. Disaster claims run under their own provision.

Three years to file. File within three years of buying or completing the replacement home. File later and relief starts only in the year you file, so you lose the years in between.

A Worked Example

A 68-year-old couple owns a home in San Jose. They bought it decades ago, and their factored base year value is $185,000. They sell for $1,600,000 and buy in Roseville for $850,000, closing four months later.

The replacement cost less than the original sold for, so nothing is added. Their base year value transfers unchanged.

• Taxable value in Roseville with the transfer: $185,000, or roughly $1,850 a year at one percent.
• Without it: $850,000, or roughly $8,500 a year.

The transfer is worth about $6,650 every year, and the gap widens as the alternative base grows two percent annually. Over fifteen years in the home, that is well over $100,000.

They file BOE-19-B with the Placer County assessor in Auburn, not with Santa Clara, and they ask Santa Clara to certify their base year value for Placer.

Mistakes That Cost Movers the Transfer

Filing with the county you left. The claim goes to the county where the new home sits.

Assuming the old county rules still apply. Propositions 60 and 90 are gone. Every county takes the transfer now.

Missing the two-year window. It runs from sale to purchase in either direction, and it does not stretch.

Waiting past three years to file. Late relief is prospective only, and the intervening years are simply lost.

Skipping the homeowners’ exemption on the new home. The exemption is what proves the home is your principal residence.

Forgetting the certification. Request it from your old county as soon as you close.

Summary

• A homeowner 55 or older, disabled, or a disaster victim can move a low tax base from any California county to any other.
• File with the assessor of the county where the replacement home sits, not the one you left.
• If the replacement costs the same or less, the base year value transfers with no adjustment.
• Buying after selling adds a five percent cushion in the first year, ten percent in the second.
• Buy and sell within two years, use the benefit up to three times, and keep both homes as principal residences.
• The old county-by-county restrictions under Propositions 60 and 90 are gone, and San Joaquin, which never accepted intercounty transfers, now must.
• Request a base year value certification from your old county early, and file within three years.
