The average real estate commission in Contra Costa County in 2026 is 5–6% of the home's sale price. On the $830K Contra Costa County median sale price (Redfin Contra Costa County), that's $41,500–$49,800 per sale — and on Danville, Lafayette, Orinda, San Ramon, and Walnut Creek's $1.5M–$2.25M premium tier, total commission tops $90,000–$135,000. On Alamo, Diablo, and Blackhawk $3M–$5M estates, $150,000–$300,000+. With traditional commissions averaging $46,000 on a typical sale, understanding your options is critical. Loqol (Sunday Real Estate Brokerage Inc. dba Loqol), CA DRE #02261474, offers a full-service California brokerage model with a 2.5% seller-side commission when you onboard through Loqol, providing dedicated licensed agents and comprehensive marketing.
This is the comprehensive 2026 guide to what Contra Costa County real estate agents actually charge, how the commission math breaks down across Walnut Creek, Concord, Danville, San Ramon, Lafayette, Orinda, Moraga, Alamo, Diablo, Pleasant Hill, Martinez, Pittsburg, Antioch, Brentwood, Oakley, Discovery Bay, Richmond, El Cerrito, Hercules, Pinole, and El Sobrante, what's negotiable and what isn't, and how a modern full-service model compares at every Contra Costa price tier.
What Contra Costa County Real Estate Agents Actually Charge in 2026
The short answer: 5–6% of the sale price. The listing-side commission typically runs 2.5–3%, the buyer-side commission is negotiated in the buyer's offer post-August-2024 NAR settlement, and the seller historically covers both at closing (though that's changing — see below).
The longer answer: traditional Contra Costa County brokerages — Compass East Bay, Coldwell Banker, Keller Williams East Bay, Re/Max Accord, Vanguard Properties, Christie's International, Intero / BHHS Drysdale, and the long tail of Lafayette / Orinda / Walnut Creek boutique independents — all run the same percentage-based commission structure across the county's 19 incorporated cities and unincorporated communities. The structure doesn't vary by city; only the dollar outcome does.
The 2024 NAR settlement changed buyer-agent compensation disclosure rules — buyer-side commission is no longer automatically baked into the MLS, and buyer-agent compensation is now negotiated in the buyer's offer rather than pre-set by the seller at listing time. In practice, Contra Costa County sellers in 2026 are split: some still offer 2.5% on the MLS to keep buyer-agent foot traffic flowing, others decline and let the buyer's offer specify what (if anything) the seller is asked to cover.
So the gross commission spread Contra Costa sellers pay in 2026 runs 3–6% — with the 3% floor for sellers using limited-service MLS companies or aggressive negotiation, and the 6% ceiling for sellers who use a traditional listing agent and cover the buyer's agent in full.

How Contra Costa County Commissions Break Down by City
Contra Costa County isn't a single price tier. The county's ~$830K median (Redfin Contra Costa) hides a ~9x spread across cities — from Antioch / Pittsburg's ~$575K commuter tier to Alamo / Diablo / Blackhawk's $3.5M–$5M+ estate market. Commission costs scale linearly with price, so the same 5–6% structure produces wildly different dollar outcomes:
| City / Community | Approx. Median Sale | 6% Commission | Charlie Tier | Listing side at Loqol's 2.5% |
|---|---|---|---|---|
| Antioch | ~$575K | $34,500 | 2.5% listing side = $14,375 | $14,375 |
| Pittsburg | ~$575K | $34,500 | 2.5% listing side = $14,375 | $14,375 |
| Oakley | ~$635K | $38,100 | 2.5% listing side = $15,875 | $15,875 |
| Hercules | ~$700K | $42,000 | 2.5% listing side = $17,500 | $17,500 |
| Richmond | ~$675K | $40,500 | 2.5% listing side = $16,875 | $16,875 |
| Pinole | ~$725K | $43,500 | 2.5% listing side = $18,125 | $18,125 |
| Contra Costa County (overall) | ~$830K | $49,800 | 2.5% listing side = $20,750 | $20,750 |
| Brentwood | ~$890K | $53,400 | 2.5% listing side = $22,250 | $22,250 |
| Discovery Bay | ~$925K | $55,500 | 2.5% listing side = $23,125 | $23,125 |
| El Cerrito | ~$1.0M | $60,000 | 2.5% listing side = $25,000 | $25,000 |
| Walnut Creek | ~$1.05M | $63,000 | 2.5% listing side = $26,250 | $26,250 |
| Pleasant Hill | ~$1.05M | $63,000 | 2.5% listing side = $26,250 | $26,250 |
| Martinez | ~$845K | $50,700 | 2.5% listing side = $21,125 | $21,125 |
| Concord | ~$835K | $50,100 | 2.5% listing side = $20,875 | $20,875 |
| San Ramon | ~$1.55M | $93,000 | 2.5% listing side = $38,750 | $38,750 |
| Moraga | ~$1.6M | $96,000 | 2.5% listing side = $40,000 | $40,000 |
| Danville | ~$2.0M | $120,000 | 2.5% listing side = $50,000 | $50,000 |
| Lafayette | ~$2.2M | $132,000 | 2.5% listing side = $55,000 | $55,000 |
| Orinda | ~$2.3M | $138,000 | 2.5% listing side = $57,500 | $57,500 |
| Alamo | ~$3.5M | $210,000 | 2.5% listing side = $87,500 | $87,500 |
| Diablo / Blackhawk | ~$5M+ | $300,000+ | 2.5% listing side = $125,000 | $125,000 |
The compounding read: at the Antioch / Pittsburg $575K commuter tier, a traditional 6% commission costs $34,500. At Alamo $3.5M, it reaches $210,000. At Diablo / Blackhawk $5M+ estates, it exceeds $300,000. With Loqol's 2.5% seller-side commission, the listing fee is kept to a manageable percentage, allowing sellers to retain more of their equity while receiving full-service representation.
Why Contra Costa County Sellers Pay So Much in Commission
Three structural reasons Contra Costa County's 5–6% commission structure persists into 2026:
1. The MLS still defaults to seller-paid buyer-agent compensation. Even after the August 2024 NAR settlement removed the requirement to advertise buyer-side commission on the MLS, most Contra Costa listing agents still recommend offering 2.5% to the buyer's agent to "stay competitive" with neighboring listings. The reality: sellers can decline, and increasingly are declining, especially at the $1M+ premium tier where the buyer pool is sophisticated.
2. Brand-name brokerages don't compete on price. Compass, Coldwell Banker, Keller Williams, and the boutique Lafayette / Orinda / Walnut Creek independents all run 2.5–3% listing-side commission as the standard quote. They compete on agent reputation, marketing, and sub-market expertise — not on commission rate. Sellers who don't negotiate get the standard quote.
3. Premium-tier seller psychology. At the $1.5M+ San Ramon / Moraga / Danville tier, sellers often default to "I'll pay the 6% because I want the best representation." The math doesn't work: paying 6% on a $2M Danville home is $120,000 — equivalent to 6 years of property tax. A modern full-service alternative with competitive pricing is almost always net-better.
Contra Costa County Commission vs. Adjacent Bay Area Counties
| County | ~2026 Median | 6% Commission | Listing side at Loqol's 2.5% |
|---|---|---|---|
| Alameda County | ~$1.1M | $66,000 | $27,500 |
| Contra Costa County | ~$830K | $49,800 | $20,750 |
| Marin County | ~$1.5M | $90,000 | $37,500 |
| San Mateo County | ~$1.93M | $115,800 | $48,250 |
| Santa Clara County | ~$1.65M | $99,000 | $41,250 |
Contra Costa County has the second-lowest median home price among Bay Area counties behind Solano. The potential to retain more equity is identical, and Contra Costa has the highest range of any Bay Area county (Antioch's $575K to Diablo's $5M+), so the difference in commission at the premium tier is largest in absolute dollars in the county's Lafayette / Orinda / Alamo / Diablo / Blackhawk band.

- $1M–$2M tier (Walnut Creek, Pleasant Hill, El Cerrito, San Ramon, Moraga) → For a $1.5M home, a 2.5% seller-side commission is $37,500, compared to $75,000–$90,000 under traditional 5–6% structures.

What's Negotiable on Contra Costa Real Estate Commission in 2026
Five things Contra Costa sellers can negotiate but most don't:
1. The listing-side commission rate. Standard quote is 2.5–3%. At the $1.5M+ tier, most agents will agree to 1.5–2% if the seller pushes back. At the $3M+ tier, 1–1.5% is achievable.
2. The buyer-side commission. Post-August-2024 NAR settlement, the seller is no longer required to offer buyer-side commission. The buyer's offer specifies what the buyer asks the seller to cover. Sellers can decline outright, or counter to lower amounts.
3. Marketing budget contribution. Listing agents often roll professional photography, drone, staging, and 3D virtual tour costs into the commission. Sellers can negotiate to pay these separately at lower retail rates and reduce the commission accordingly.
4. Length of listing agreement. Standard is 6 months exclusive. Negotiate down to 60–90 days with renewal — this puts pressure on the listing agent to actually move the home.
5. Cancellation rights. Most listing agreements have no easy out for the seller. Negotiate a 30-day cancellation right without penalty if the agent isn't performing.
Loqol's 2.5% seller-side commission model simplifies this process by providing a clear, competitive rate upfront, backed by a dedicated licensed agent and comprehensive marketing support.
FAQ — Contra Costa County Real Estate Commission 2026
What's the average real estate commission in Contra Costa County in 2026?
5–6% of the sale price. Listing-side typically 2.5–3%, buyer-side commission negotiated in the buyer's offer post-August-2024 NAR settlement. On a $830K county median, that's $41,500–$49,800 total commission.
How much do Walnut Creek / Concord / Danville real estate agents charge?
Same 5–6% structure as the rest of Contra Costa County. At Walnut Creek's $1.05M median, $52,500–$63,000. At Concord's $835K median, $41,750–$50,100. At Danville's $2M median, $100,000–$120,000.
Do I still have to pay the buyer's agent commission as a Contra Costa seller?
No. Post-August-2024 NAR settlement, buyer-agent compensation is negotiated in the buyer's offer, not pre-set by the seller in the listing. Contra Costa sellers can decline outright, counter to a lower amount, or accept what the buyer asks. If the seller declines, the buyer is on the hook for paying their own agent themselves.
