Free Los Angeles County Property Lookup Step-by-Step
The easiest free lookup starts with the Los Angeles County Assessor Portal. It helps you identify the AIN, property address, parcel record and assessment information before you move to tax or recorded-document searches.
After you identify the correct parcel, copy the AIN exactly. In Los Angeles County, the AIN is the key number that connects many tax, Assessor, map and document workflows.
- Open LA County Assessor property search Go to Los Angeles County Assessor Property Search or the Assessor Portal.
- Search by AIN or property address Use the AIN if you already have it from a tax bill, deed, closing document or map. If not, use the property address.
- Open the correct property record Confirm property address, AIN, assessment details, parcel information and map context before relying on the result.

Search by AIN, Address, Owner Clues or Map
Los Angeles County property research works best when you start with the AIN. Address search is easier for regular users, but AIN search is cleaner for tax bills, maps and document matching.
Search by AIN
AIN means Assessor Identification Number. Use it when you want exact matching in county property, tax and map tools. If a property has multiple parcels, check each AIN separately.
Search by address
Start with the house number and street name. If the full address fails, remove unit number, ZIP code, punctuation, apartment details and extra wording.
Search by owner clues
Owner information and real estate document searches may require party-name research. For deed and lien research, search grantor, grantee, current owner, prior owner, lender, trust, LLC and estate names.
Search by map
Map search is useful for hillside parcels, vacant land, multi-parcel commercial property, condominium projects, easements, alley parcels and properties where the address does not clearly identify one parcel.
Assessor Records, Parcel Details and Assessed Value
The Los Angeles County Assessor is the official source for many property assessment records. The Assessor Portal supports basic search, legal search and map search, including search by AIN or address.
Use Assessor records when your question is about assessed value, taxable value context, property address, AIN, legal description clues, parcel map context, base-year value, exemptions or whether the county property details look correct.
| Assessor Field | What It Helps You Check | Why It Matters |
|---|---|---|
| AIN | Unique Assessor Identification Number. | Best field for tax bills, maps, assessment and document matching. |
| Property address | Physical location of the parcel. | Confirms you are viewing the correct property. |
| Assessed value | County assessment value context. | Important for property tax and appeal questions. |
| Parcel map context | Parcel location and nearby parcels. | Useful before GIS, deed, zoning or permit research. |
| Legal description clues | Tract, lot, block or legal reference where available. | Helpful when searching older deeds or maps. |
| Exemption/value clues | Assessment and exemption-related context. | Useful for homeowner, transfer and review questions. |

- Do not expect phone index searches: LA County’s real estate viewing guidance says telephone requests for index searches are not accepted.
- Older records may require in-person review: The county provides different viewing locations/floors based on record date ranges at Norwalk headquarters.
- Assessor public-record direction may send ownership questions to RR/CC: Property ownership information requests can involve the Registrar-Recorder/County Clerk.
- City of LA permits are separate: For Los Angeles City building records, use LADBS property records and city tools.
- Tax bill timing matters: Current secured tax information can have seasonal availability limits, so use official tax portal guidance.
- GIS is not a survey: Use recorded maps, legal descriptions and licensed surveyors for boundary decisions.
- Keep one research packet: Save Assessor record, tax bill, payment confirmation, deed reference, GIS map and permit search result together.
