Seller Closing Costs in the East Bay Explained

Selling a home in the East Bay triggers county documentary transfer taxes, potential city transfer taxes, escrow and title fees, a Natural Hazard Disclosure report, and agent commissions. The biggest variable is which city you're in, Berkeley and Richmond carry some of the highest transfer tax rates in the Bay Area, and all fees are negotiable by contract.

What does it really cost to sell a home in the East Bay?

Selling a home in Alameda or Contra Costa County involves several layers of closing costs: a countywide documentary transfer tax, a potential city-level transfer tax that can be substantially larger, escrow and title fees, a Natural Hazard Disclosure report, agent commissions, and a handful of smaller line items. The total varies significantly by city and price point, and nearly every line item is negotiable by contract, there is no single statewide rule that dictates who pays what.

Key Takeaways

Both Alameda and Contra Costa Counties charge a countywide documentary transfer tax of $1.10 per $1,000 of sale price under California Revenue & Taxation Code §11911, but city transfer taxes layered on top can far exceed that base rate.
Berkeley's city transfer tax is 1.5% on sales up to $1.7 million and 2.5% on sales over $1.7 million, and the higher rate applies to the full sale price, not just the amount above the threshold.
Richmond carries one of the highest city transfer tax burdens in Contra Costa County, starting at $7.00 per $1,000 for sales under $1 million and rising to $30.00 per $1,000 above $10 million.
Escrow fees and transfer taxes are negotiable by contract, local custom in the East Bay leans toward a roughly 50/50 escrow split and seller-paid owner's title insurance, but competitive markets regularly produce different allocations.
Agent commissions are negotiated professional fees, not set by law or any fixed rate, they are typically the largest single line item in a seller's closing costs.

What are the main closing cost categories for East Bay sellers?

Every East Bay seller closing cost falls into one of a handful of buckets. Understanding each one, and knowing which are fixed by statute versus freely negotiable, is how you avoid surprises at the closing table.

County documentary transfer tax

The countywide documentary transfer tax is the one cost that applies to every arm's-length sale in both Alameda and Contra Costa Counties. Per the Alameda County Auditor-Controller/Clerk-Recorder and the Contra Costa County Clerk-Recorder, the rate is $0.55 per $500 of consideration, which works out to $1.10 per $1,000 of the property's full value. This is the statutory baseline under California Revenue & Taxation Code §11911.

On its own, the county documentary transfer tax is a relatively modest line item on a Bay Area sale. The bigger variable is what your city adds on top of it.

City transfer taxes, where the real variation lives

This is the line item that catches the most sellers off guard, and it's the first thing I look at when I'm building a net sheet for a client. In unincorporated Alameda or Contra Costa County, areas with no city-level tax, you pay only the county rate. But most East Bay cities impose their own transfer tax on top of the county rate, and the differences are significant.

Here's a comparison of the key city transfer tax structures in effect as of September 2026, based on the most recent official and county-published rates available:

Jurisdiction	County	City Transfer Tax Rate	Structure
Unincorporated areas	Alameda or Contra Costa	None	County rate only ($1.10/$1,000)
Berkeley	Alameda	1.5% (up to $1.7M) / 2.5% (over $1.7M)	Two-tier; higher rate applies to full price once threshold is crossed
Oakland	Alameda	Graduated tiers by price band	Lower bands under $300K and up to $2M; higher rates above $2M and $5M
Richmond	Contra Costa	$7.00–$30.00 per $1,000	Four tiers: under $1M / $1–3M / $3–10M / over $10M
Other Alameda cities (Hayward, San Leandro, Emeryville, Piedmont, Alameda city)	Alameda	Varies by city	City-specific rates layered on county base

A few things worth flagging from my work with sellers across the East Bay:

Berkeley's threshold effect is real. Once a sale crosses $1.7 million, the 2.5% rate applies to the entire sale price, not just the dollars above $1.7M. On a sale just over that threshold, the jump in tax owed is meaningful. In a market where many Berkeley single-family homes cross that line, this is a number worth running before you set your list price.
Oakland's price bands create sensitivity near band edges. A small difference in final sale price can push a transaction into a higher tax tier. I always flag this when we're discussing pricing strategy with Oakland sellers.
Richmond's city transfer tax is among the highest in the Bay Area. At $12.50 per $1,000 for sales between $1M and $3M, on top of the county's $1.10 per $1,000, this is a significant line item that deserves its own conversation in any net sheet discussion.

Who pays the transfer tax? According to county closing cost guides and title company practice, transfer taxes are negotiable by contract, there is no California law requiring the seller to pay. Local custom in many East Bay cities leans toward the seller paying, or a 50/50 split between buyer and seller, but this varies by city and by market conditions. In competitive offer situations, I've seen buyers agree to absorb more of the transfer tax burden. Always confirm the allocation in your purchase agreement.

Escrow fees and owner's title insurance

California does not mandate which party pays escrow or title fees, it's purely a matter of contract and local custom. In Alameda and Contra Costa Counties, the general practice described by title companies is a roughly 50/50 escrow fee split between buyer and seller, with the seller customarily paying for the owner's title insurance policy that protects the buyer's ownership interest. But "custom" is not "law," and I see exceptions regularly in competitive East Bay markets, buyers sometimes agree to cover more of these costs to strengthen their offer.

Owner's title insurance is a one-time premium paid at closing. The exact cost depends on the sale price and the title company used; your escrow officer will provide a quote specific to your transaction.

Natural Hazard Disclosure report

California sellers are required to provide buyers with a Natural Hazard Disclosure (NHD) report as part of the disclosure package. By custom, though not by law, the seller typically pays for this report. Major NHD vendors offer standard residential packages, with pricing varying based on whether environmental or HOA add-ons are included. It's a relatively modest cost, but it belongs on your pre-listing checklist.

Agent commissions

Commissions are negotiated professional fees, they are fully negotiable and not set by law. There is no standard, typical, or customary rate. The listing-side fee is agreed in your listing agreement, and any compensation a seller chooses to offer a buyer's agent is optional and separately negotiable. Commissions are typically the largest single line item in a seller's closing costs, but the right number for your situation depends on your home, your goals, and what you negotiate directly with your agent. If you want to know what that looks like for your specific property, that's a conversation worth having before you sign anything.

Other line items to expect

A complete East Bay seller net sheet also includes:

County recording fees and document preparation or wiring fees charged by the title/escrow company and county recorder
HOA transfer and document fees if your property is in a common-interest development (this applies to many homes in Five Canyons, Stonebrae, Gale Ranch, and Windemere)
Prorated property taxes covering your share of the tax year up to the closing date
Any outstanding municipal or utility charges attributable to your period of ownership

These line items are relatively standardized across East Bay transactions, but exact amounts are vendor- and county-specific. Your closing agent will provide an itemized preliminary settlement statement before closing.

How do these costs actually affect your net proceeds?

The honest answer: it depends on your city, your price point, and what you negotiate. That's not a dodge, it's the reality of a market where Berkeley's transfer tax at $1.8M looks completely different from an unincorporated Contra Costa sale at the same price, and where every allocation from escrow to title is subject to negotiation.

What I do with every seller before we list is build a personalized net sheet that maps out every line item specific to their address, price band, and likely contract terms. That exercise almost always surfaces at least one cost that wasn't on the seller's radar, most often a city transfer tax or an HOA fee. If you're planning to sell and you want to see what your actual net looks like, especially if you're also buying at the same time, that's exactly the conversation I'm here to have.

Frequently Asked Questions

Who pays the transfer tax when selling a house in Alameda or Contra Costa County, buyer or seller?

Transfer taxes in both counties are negotiable by contract, California law does not require either party to pay. Local custom in many East Bay cities leans toward the seller paying, or a 50/50 split, but this varies by city and market conditions. Always confirm the allocation explicitly in your purchase agreement rather than assuming local custom will govern.

What closing costs do East Bay sellers usually pay besides agent commissions?

Beyond commissions, East Bay sellers typically see county and city documentary transfer taxes, owner's title insurance, a share of escrow fees, a Natural Hazard Disclosure report, county recording and document prep fees, prorated property taxes, and HOA transfer or document fees if the property is in a common-interest development. The exact amounts depend on your city, price point, and what's negotiated in your contract, your closing agent will provide an itemized settlement statement before closing.

Are escrow and title fees split 50/50 in Alameda and Contra Costa, or does the seller pay more?

The general local custom described by Bay Area title companies is a roughly 50/50 escrow fee split, with the seller customarily paying for the owner's title insurance policy. But this is custom, not law, California does not mandate any particular allocation. In competitive markets, I regularly see buyers agree to cover more of these costs as part of a stronger offer, so the final split depends entirely on what's negotiated in your purchase agreement.

The bottom line on East Bay seller closing costs

The biggest mistake I see sellers make is assuming their closing costs are just "agent commission plus a little extra." In the East Bay, city transfer taxes alone, particularly in Berkeley, Oakland, and Richmond, can be a major line item that deserves its own planning conversation before you set a list price.

I build personalized net sheets for every seller I work with, specific to their city, price point, and likely contract terms.
