Find a property owner in Alameda County, California

Updated October 2026 · Alameda County, California

Alameda County takes in Oakland and the surrounding area. In California, deeds are recorded by the county recorder, and property is assessed by the county assessor. Those offices give you the owner of record and mailing address one parcel at a time; for a whole list, an owner-data tool returns owners, phones (DNC flagged) and emails in one pass.

What's on a Alameda County property record

Working Alameda County records

Compare the owner mailing address with the property address. When they differ, the owner is usually absentee — a landlord or second-home owner — and often worth a different pitch than an owner-occupant.

Common questions

How do I find the owner of a property in Alameda County?

The Alameda County property appraiser or assessor website publishes the recorded owner name and mailing address for every property in the county at no charge. For a list of addresses, an owner-data tool resolves each one directly to the verified owner with phones (DNC flagged) and emails.

Where do I find Alameda County property records?

Assessment and owner-of-record data come from the county assessor; recorded deeds, mortgages and liens are with the county recorder. Most Alameda County offices offer an online search by address or parcel number.

Is it legal to look up property owners in Alameda County?

Yes. California deed and assessment records are public. Calling or texting the owner is a separate question: the federal TCPA and the Do Not Call registry apply, so screen numbers before you dial.
