This page helps users handle a property search in Los Angeles County, California, by explaining the main Assessor tools, map options, and office contacts for property record questions.

The Los Angeles County Assessor Portal is the main public path for searching assessment information, while the Los Angeles County Assessor’s Office handles staff-assisted questions, public records requests, mapping, and data sales.

Use the search the Assessor Portal option when you want to look up detailed property and assessment information for a parcel in Los Angeles County.

Have one of these details ready before searching:

  • Assessor’s Identification Number, also called an AIN
  • Property address
  • Legal search details, if using the portal’s Legal Search option

The portal supports Basic Search, Legal Search, Map Search, and search by AIN or address. Choose the search type that matches the information you already have.

  • Open the Assessor Portal.
  • Select the search option that matches your available information.
  • Enter the AIN, address, or legal search details.
  • Review the property and assessment information returned by the portal.

For map-based property research, use the open the Assessor Portal Map Search tool. It can help when you need to work from a map location instead of starting with an AIN or full address.

The map search includes Assessor Parcels and reference layers such as Supervisorial Districts, Cities, Communities, ZIP Codes, School Districts, Map Books, Field Books, Oil & Gas Fields, Public Land Survey, unincorporated zoning, street labels, Mobile Home Parks, and Tax Rate Areas.

Base layers include Street, 2025 Aerial, Palisades Fire 2025 Aerial, Eaton Fire 2024 Aerial, 2023 Aerial, 2020 Aerial, 2017 Aerial, and 2014 Aerial.

Property ownership and public records requests

California law prohibits publishing identifying information such as a homeowner’s name online without written permission from the owner. For ownership information, the Assessor directs users to request property ownership information from the County Registrar-Recorder/County Clerk.

The Assessor’s Office also maintains assessment-related public records. Common public inquiry records include assessment rolls, assessment maps, lists of property transferred in the last two years, organizational exemption claims and supporting documents, market data, and property characteristic information.

Record request tip: the Assessor’s Office states that routine record duplication is not charged under its policy.

Multi-property data and GIS parcel data

For single-property information by phone, the Assessor directs users to its public service number. For multi-property datasets, use the Property Data Sales unit rather than the general property search path.

The Assessor’s Office maintains assessment records for real and personal property in Los Angeles County. Multi-parcel records may be available as CD-ROM, DVD, hardcopy, or online access. The office also offers a GIS Tax Parcel Base Map.

The fee-based Assessor Property Database Inquiry System provides remote access to public property records one record at a time. Parcels are indexed by Assessor’s Identification Number, assessee name, and situs address.
