How Alameda County Tax Auctions Work

Alameda County conducts tax-defaulted property auctions through Bid4Assets.com. Properties become tax-defaulted after 5 years of unpaid property taxes, at which point the county treasurer has the authority to sell them at public auction to recover the outstanding debt.

What gets auctioned?

The auction includes residential homes, vacant land, commercial properties, and condos across cities like Oakland, Hayward, Fremont, Berkeley, and more. Each property has a minimum bid that typically covers the outstanding taxes, penalties, and fees.

How bidding works

Auctions run online over several days on Bid4Assets. Bidders must register and submit a deposit before the auction opens. Bidding starts at the minimum bid and increases in set increments. The highest bidder at the close wins the property.
