If you’re buying or selling a home, The City of Berkeley transfer tax is one of the largest line items in your closing statement that has nothing to do with your agent, your lender, or your home inspector. It’s a tax the City collects every time real estate changes hands, and on a typical Berkeley sale it runs into the tens of thousands of dollars. As of 2026 the rate is 1.5% for properties up to $1.7 million and 2.5% for properties over $1.7 million. On January 1, 2027, Measure W, approved by voters in 2024, replaces that two-tier structure with three tiers and makes the higher rates permanent.
Here is how the tax works today, what’s changing on January 1, 2027, and how these changes impact buyers and sellers on either side of that date.
What is Berkeley’s real property transfer tax, and what does it cost right now?
Berkeley’s transfer tax is a one-time tax on the full sale price of a property, charged by the City whenever ownership transfers. For 2026 the rate is 1.5% on sales up to $1.7 million and 2.5% on sales above $1.7 million, and it applies to the entire value, not just the portion above the threshold.
That last point is important to understand. The tax rate is not marginal for values above $1.7M. A home that sells for $1.7 million owes $25,500 ($1.7M x 1.5%); a home that sells for $2 million owes $50,000 ($2M x 2.5%). The $2 million sale is taxed at 2.5% on all $2 million, not at 1.5% on the first $1.7 million and 2.5% on the rest. The rate that applies to your sale applies to the whole number.
This is the City of Berkeley’s tax alone. It sits on top of the Alameda County documentary transfer tax of $1.10 per $1,000 of value, roughly 0.11%, or about $2,200 on a $2 million sale. The county piece is relatively small compared with the larger city tax, but it is still important to understand all of your closing costs when buying or selling.
Who pays the transfer tax in Berkeley, buyer or seller?
In Berkeley, the local convention treats the two taxes differently. The seller customarily pays the Alameda County transfer tax, and the buyer and seller generally split the City of Berkeley transfer tax. None of this is fixed by law: who pays each tax is a term of the purchase contract, and every piece of it is negotiable for any given transaction.
The split matters because the city tax is the large one. On a 2.5% sale, half of that figure is still a meaningful number, and I’ve seen the split move in either direction depending on how a negotiation is going. Budget for your customary share, and treat the allocation as one more deal point to address during contract negotiations.
If you’re a buyer, the other question worth asking early is whether any part of the tax can be rebated through seismic work, because that’s an additional lever available to reduce the cost. More on that below.
What was Measure P, and why does it still matter?
Measure W didn’t create Berkeley’s higher transfer tax. Measure P did, in November 2018, with 72% voter approval. Measure P raised the rate on the city’s more expensive sales to 2.5% and dedicated the revenue to homeless services, funding street outreach, emergency shelters, and permanent housing. It also created the city’s Homeless Services Panel of Experts to advise on how the money is spent, and it generates about $11 million a year on average.
Measure P mattered for a reason that became the whole point of Measure W: the increase it created was temporary. The enhanced portion of the tax, the extra 1% that lifted the top rate from 1.5% to 2.5%, was scheduled to expire on January 1, 2029. Without further action, Berkeley’s top transfer-tax rate would have fallen back. Measure W was the further action.
What did Measure W change, and when does it take effect?
Berkeley voters approved Measure W in November 2024 with 61% approval. It does two things. First, it removes the January 1, 2029 expiration date, making the higher transfer tax permanent until the City repeals it. Second, it replaces the single 2.5% top rate with a three-tier structure that charges even more for the most expensive sales.
Effective January 1, 2027, the rates become:
- 2.5% for properties valued at $1.6 million or higher
- 3% for properties valued at $1.9 million or higher
- 3.5% for properties valued at $3.0 million or higher
Properties below the first threshold continue to pay the base 1.5%. The City estimates the change will generate an additional $2 million to $4 million a year on top of what the tax already raises, and the revenue continues to support services for people experiencing homelessness.
One nuance worth understanding: the dollar thresholds move. At passage, the three breakpoints were set to the 60th, 80th, and 95th percentiles of Berkeley sales over the preceding year, and the ordinance adjusts them annually to track those same percentiles, rounded to the nearest $100,000, though the first tier can never drop below $1.6 million. The City will recalculate and publish the exact 2027 breakpoints before the new tiers take effect, so treat $1.6M / $1.9M / $3.0M as the floor, not a frozen figure. The design intent is consistent: the tax is meant to reach roughly the top third of sales, with the steepest rate aimed at the top 5%.
How will the new rates actually hit a sale after 2027?
Because the rate applies to the entire sale price, crossing a threshold is expensive. The tax doesn’t increase the costs above each breakpoint: it re-rates the whole sale. Using the measure’s floor thresholds for illustration:
- A $1.85 million sale at 2.5% owes $46,250.
- A $1.90 million sale at 3% owes $57,000.
That’s $50,000 more in price producing roughly $10,750 more in tax. The same cliff sits at the top tier: a $2.99 million sale at 3% owes about $89,700, while a $3.0 million sale at 3.5% owes $105,000, which is $10,000 more in price and more than $15,000 more in tax.
I point this out because it changes how you think about a list price or a counteroffer that lands just over a line. The marginal dollar near a threshold can carry an outsized tax cost, and on the city portion that cost is shared between buyer and seller by custom. It’s not a reason to underprice a home, since the market sets value, not the tax table, but it is a reason to know exactly where the breakpoints fall in the year you sell and to model the closing math before you set a number.
Can you reduce Berkeley’s transfer tax?
Yes, and this is something many buyers and sellers don’t know about. Berkeley rebates up to one-third of the base 1.5% transfer tax for voluntary seismic upgrades and home-hardening work on residential buildings, or mixed-use buildings with at least two residential units. One-third of the 1.5% base works out to about 0.5% of the sale price. On a $1.7 million home, that’s a rebate of roughly $8,500.
A few specifics that matter:
The rebate applies to the base 1.5% only, not to the enhanced 1% that Measure P and Measure W added. So it reduces the floor of your tax, not the higher-tier portion.
Qualifying work is the structural strengthening that older Berkeley houses so often need: bolting the foundation to the mudsill, adding shear walls, bracing cripple walls, securing or removing unreinforced masonry chimneys, and anchoring water heaters. The work must be permitted, inspected, and either completed before the sale or within a year of it, and a buyer can claim the rebate for retrofit work they complete after closing.
There’s a telling date in the fine print: eligible expenses are those incurred on or after October 17, 1989. That’s the day of the Loma Prieta earthquake. Berkeley wrote its retrofit incentive to begin the moment the region’s last major quake reminded everyone why it mattered. For a city sitting on the Hayward Fault, the rebate is less a loophole than an opportunity: do the safety work, document it, and the City returns a piece of the tax.
If you’re considering this, confirm eligibility with the City’s Building & Safety Division before the work begins. The permit has to carry specific language about the transfer-tax reduction, and the rebate is paid only after final inspection and an application with receipts.
What does this mean if you’re buying or selling in the next two years?
If you expect to sell before January 1, 2027, the current two-tier structure applies: 1.5% up to $1.7 million and 2.5% above it for 2026. The looming expiration that Measure P built in has been eliminated, so there’s no specific rush. Measure W made the higher rate permanent rather than letting it lapse.
If you’ll sell in 2027 or later at a price near $1.9 million or $3.0 million, find out where that year’s published thresholds land and model the tax at both the lower and higher rate. The difference across a breakpoint is real money, and on the city portion it’s money that, by custom, is split between the two sides of the deal.
If you’re buying an older home, which in Berkeley means most homes, treat the seismic rebate as part of your retrofit plan, not a separate project. The work you’d want to do anyway for safety and insurance can return up to about 0.5% of the purchase price, and a buyer can complete it after closing.
Regardless of your timing to buy or sell, I help my clients develop a custom negotiation strategy to deliver the best NET financial outcome. As a seller, it may sometimes make sense to accept a slightly lower value when selling your home to avoid the step-up in transfer tax expenses. As a buyer, you can create incentives for the homeowner to accept a lower offer which saves both parties money and delivers the most net cash to the seller.
And whichever side you’re on, calculate the specific number early. I have built net sheet calculators for both buyers and sellers to help you understand your all-in closing costs, including transfer taxes. The transfer tax is one of the few large closing costs you can calculate to the dollar well in advance. Costs you can see are costs you can plan around, and I’d rather you see this one in the first conversation than at the signing table.
If you want, I’m glad to run the specific transfer-tax math on a property you’re weighing, including how the seismic rebate would change it. Feel free to reach out for a personal consultation.
Frequently Asked Questions
Common questions about Berkeley’s transfer tax
For 2026, Berkeley’s city transfer tax is 1.5% of the sale price on properties up to $1.7 million and 2.5% on properties over $1.7 million. The rate applies to the entire sale price, so a $2 million sale owes $50,000. This is separate from the Alameda County transfer tax.
By local custom, the seller pays the Alameda County transfer tax, and the buyer and seller split the City of Berkeley transfer tax. None of this is set by law. Who pays each tax is a term of the purchase contract and is negotiable on every transaction.
Measure W is a Berkeley ballot measure that voters approved in November 2024 with 61% support. Effective January 1, 2027, it replaces the single 2.5% top rate with three tiers and removes the January 1, 2029 expiration date that Measure P had set, making the higher transfer tax permanent until repealed.
Starting January 1, 2027, the rates are 2.5% for properties valued at $1.6 million or higher, 3% for properties at $1.9 million or higher, and 3.5% for properties at $3.0 million or higher. Properties below the first threshold still pay 1.5%. These thresholds adjust annually and will be recalculated before the new tiers begin.
It applies to the entire sale price, not just the portion above the threshold. The rate that matches your sale price is charged on the whole number. That is why crossing a threshold raises the tax sharply: a $1.9 million sale taxed at 3% owes $57,000, while a $1.85 million sale taxed at 2.5% owes $46,250.
Yes. Berkeley rebates up to one-third of the base 1.5% transfer tax, about 0.5% of the sale price, for voluntary seismic upgrades and home-hardening work on residential or qualifying mixed-use buildings. The rebate applies to the base rate only, not the enhanced portion. The work must be permitted and inspected, and a buyer can complete it within a year of closing.
Yes. The City of Berkeley transfer tax is charged on top of the Alameda County documentary transfer tax of $1.10 per $1,000 of value, which is about 0.11%. On a $2 million sale the county portion is roughly $2,200, while the city portion is the larger figure.
This information is general and current as of 2026. Transfer tax rates, thresholds, and rebate eligibility can change; confirm the figures with the City of Berkeley before relying on them for a transaction.
