Contra Costa County foreclosure auctions

Contra Costa trustee sales split between an Auction.com room in Pleasant Hill and outdoor civic venues in Pittsburg — a suburban county where the foreclosure map runs from Richmond to Brentwood.

Contra Costa is a county of contrasts. Its western edge — Richmond, San Pablo, El Cerrito — is older, denser Bay Area; its center (Concord, Walnut Creek, Pleasant Hill, Martinez) is post-war suburbia; and its eastern flank (Antioch, Pittsburg, Brentwood, Oakley) holds the newest subdivisions and, historically, the county's highest foreclosure volume. Cingore tracks trustee sales across all of it, and the mix matters: an Antioch short-sale-era tract home, a Walnut Creek ranch near the BART line, and a Richmond bungalow are three very different auction purchases even when the opening bids look similar.

Eastern Contra Costa deserves special attention from value-focused buyers. The Antioch–Pittsburg–Brentwood corridor absorbed enormous growth in the 1990s and 2000s, and it still produces a steady share of the county's defaults. Homes there are typically newer, larger, and simpler to evaluate than the county's older western stock — but distances are real, and rental and resale markets behave differently than in the county's BART-served core.

Where trustee sales are held in Contra Costa County

Contra Costa sales in our listings cluster at two venues, with some sales run online:

Some Contra Costa properties are also sold with in-person and remote bidding through Auction.com. The recorded Notice of Trustee Sale for your property states the actual venue — trustees differ, and the notice, not habit, is what counts.

How the process runs here

Sales here follow the standard California non-judicial timeline — Notice of Default, a reinstatement window of at least three months, then a Notice of Trustee Sale recorded with the Contra Costa County Clerk-Recorder at least 20 days before the auction. Because the county is large and two venue systems run in parallel, the most common beginner mistake in Contra Costa is logistical: showing up at the Pleasant Hill room for a sale that was noticed for Pittsburg, or vice versa. Read the venue line of the NOTS carefully, and re-confirm it the morning of the sale; postponements are announced sale-by-sale and do not always propagate to listing sites quickly.

Before you bid in Contra Costa County

• Confirm the venue twice. Two systems (Pleasant Hill and Pittsburg) plus online sales make Contra Costa the easiest county in the region to attend wrong.
• HOAs are everywhere in the newer east. Antioch, Brentwood, and San Ramon subdivisions often carry HOA dues and sometimes Mello-Roos taxes; both survive the sale and change your real cost.
• Commute value drives resale. Proximity to Highway 4, Highway 24, and BART stations (Pittsburg, Concord, Walnut Creek, Richmond) is the single biggest value swing in the county.
• Check for solar and PACE/HERO assessments. Eastern subdivisions adopted rooftop solar early; leases and property-tax assessments may transfer to you.
