How to Search Los Angeles Property Records by AIN, Address or Map
The LA County Assessor Portal is the best first stop for parcel identity. It supports basic search, legal search and map search. Use it to identify the AIN before searching taxes, deeds, maps or property data corrections.
AIN
AIN is the 10-digit Assessor’s Identification Number, also known as map book, page and parcel. Example format: 1234-567-890.
Address
Use address search when you do not know the AIN. Try fewer address words if the first search fails.
Map Search
Use map search when the property has multiple units, hillside parcels, vacant land or an address that does not match neatly.
1
Start with AIN or addressAIN is best; address is the next best option.
▾
If you have a tax bill, use the AIN printed on it. If not, search the property address first. For apartments, condos and multi-parcel lots, verify unit and map details before moving to tax or deed records.

How to Find Los Angeles Deeds, Liens, Mortgages and Recorded Real Estate Records
The Registrar-Recorder/County Clerk maintains real estate records for Los Angeles County. These records are public, but the search method is different from many counties: LA County property records maintained by the Recorder are indexed by grantor name, grantee name and year of recording—not by street address.
| Need | Best Search Detail | Important LA County Rule |
|---|---|---|
| Grant deed / quitclaim deed | Grantor, grantee, recording year, document title, document number | Do not search only by address. Use names and recording year. |
| Deed of trust / mortgage | Borrower, lender, recording year, document type | Search later years for full reconveyance, release or substitution. |
| Lien / release | Party name, document type and year range | Recorded liens may need title or legal review before you rely on them. |
| Older record | Name + year, then appointment/in-person review | Records from 1851 to 1957 are reviewed in the lower level at Norwalk; 1958-present on the 2nd floor. |
| Copy or certified copy | Document title, names and recording year | Complete document must be purchased; selected pages are not allowed. |
