Alameda County Delinquent Tax List (Tax-Delinquent & Tax-Defaulted Properties)
17,110 Alameda County properties are behind on their property taxes — #7 of California's 58 counties and 3.9% of the statewide total. Nothing about tax delinquency is public-facing: no filing, no listing, no sign in the yard. But five years of it makes a property eligible for the county tax sale, and owners on this list disproportionately hold real equity with a cash-flow problem a sale would solve. This is the Alameda County delinquent property tax list as it stands today — the county's delinquent tax roll with the owner, loan and equity records attached — not the once-a-year tax-defaulted notice.

Alameda County Tax Sale
California is a tax-deed state: counties don't sell lien certificates, they sell the property itself, and each county sets its own tax sale calendar rather than a statewide date. A home only reaches that sale after five years of default — and the owner can redeem it right up until it happens. That runway is the point of this page: the 17,110 properties above are the pipeline those auctions are eventually drawn from, at the stage where the owner still controls the outcome.

Frequently Asked Questions
How many tax-delinquent properties are there in Alameda County?
Properant tracks 17,110 tax-delinquent properties in Alameda County as of October 12, 2026 — ranked #7 of California's 58 counties — counted from recorded county documents with releases and cancellations removed.
Why are tax-delinquent owners in Alameda County considered motivated sellers?
Because delinquency compounds: penalties accrue, and after five years the county can sell the property at its tax auction. Owners with equity but no cash flow — heirs, absentee owners, owners in transition — frequently prefer a clean sale over losing the property to the tax sale.
When is the next Alameda County tax sale?
California counties set their own tax sale calendars rather than following a statewide date, and a home only reaches one after five years of default — with the owner able to redeem it right up to the sale. The 17,110 Alameda County properties on this page are the pipeline those auctions are drawn from, years before a sale date exists.
Does Alameda County sell tax liens or tax deeds?
Tax deeds. California is a tax-deed state: there are no tax lien sales and no tax lien auctions here, because Alameda County never sells lien certificates to investors — so there is no interest rate to bid down and no lien position to hold. After five years of default the county can sell the property itself at a tax deed sale, and the buyer receives a recorded deed. Almost everyone searching for tax lien properties in California is looking for that sale, and the 17,110 properties on this page are the pipeline it is drawn from.
