Search LA County Property Records by Address or AIN, Find Tax Bills, Check Payments and Request Deeds
This quick-action guide helps Los Angeles County property owners, buyers, heirs and real-estate professionals locate the correct parcel, understand the 10-digit Assessor Identification Number, review assessed values, check annual or supplemental tax bills and request recorded property documents.
Los Angeles County does not operate a Texas-style county appraisal district. Property valuation is handled by the County Assessor, formal value disputes go to the Assessment Appeals Board, tax billing and payment go through the Treasurer and Tax Collector, and deeds are maintained by the Registrar-Recorder/County Clerk.
Use the official county portals for the final search, payment, appeal or document order.SEO Role of This LA County Page

How to Search LA County Property Records by Address
Use the Los Angeles County Assessor Portal rather than a commercial people-search, deed-selling or tax-estimate website.
Start with the street number and main street name. Add the city or ZIP code when the system shows several possible locations.
Try the address without apartment wording, punctuation, street-direction abbreviations or the full street-type suffix.
Verify the street address, city, ZIP code, parcel description and AIN. Condominiums, parking spaces and adjoining lots may use separate numbers.
Review the land value, improvement value, total assessed value, use code, year built, building area and map information.
The AIN is the most important identifier for checking bills, payment history, maps, exemptions and appeals.
Keep a dated copy with the deed, tax bill, closing papers, exemption forms and any assessment notice.
What Is the LA County Assessor Identification Number?
The Assessor Identification Number is the county’s 10-digit parcel identifier. It is commonly displayed with hyphens in a format similar to 1234-567-890.
Where to find the AIN
- Annual secured property-tax bill
- Supplemental secured property-tax bill
- Assessor property-search result
- Property Tax Portal
- Title or escrow documents
- Earlier tax-payment receipt
Why an LA County Property Search May Return No Result
| Possible Problem | What to Try | What to Verify |
|---|---|---|
| Street suffix mismatch | Search without Street, Avenue, Boulevard or Road. | The official situs address format. |
| Directional abbreviation | Remove North, South, East, West or their abbreviations. | City and ZIP code. |
| Condominium property | Search the building address and compare individual unit AINs. | Unit, parking space and storage parcel. |
| Recent parcel split or combination | Search the old and new addresses or check the map. | Active versus retired AIN. |
| New construction | Search the underlying land parcel. | Whether the improvement data has been updated. |
| Mailing address used instead of property address | Enter the physical situs address. | The parcel’s actual location. |
| Vacant or hillside land | Use map-based research or the known AIN. | Legal description and road access. |
What the LA County Property Record Shows
| Record Field | Meaning | What to Check |
|---|---|---|
| AIN | The 10-digit parcel identifier. | Use the same number across county systems. |
| Situs address | The physical address assigned to the parcel. | Unit, city and ZIP code. |
| Use code | The Assessor’s classification of the property’s primary use. | Residential, condominium, commercial, industrial or vacant use. |
| Land value | The assessed value assigned to the land. | Base-year history and ownership changes. |
| Improvement value | The assessed value assigned to taxable buildings and improvements. | New construction, additions, demolition and ADUs. |
| Total assessed value | The combined assessed land and improvement value. | Compare with notices and supplemental assessments. |
| Year built | The recorded construction year. | Original structure versus major additions. |
| Building area | The Assessor’s recorded improvement area. | Permitted living space and additions. |
| Tax-rate area | The combination of taxing agencies attached to the parcel. | Nearby properties may have different direct assessments. |
| Map reference | The parcel’s location within the Assessor mapping system. | Compare with deeds and recorded maps for legal use. |
How to Use LA County Property Data and Maps
Do not begin boundary research from a street address alone when the property contains several parcels.
Search or navigate to the parcel using the verified AIN.
Check whether the property includes a separate parking parcel, vacant lot, access strip or adjoining tract.
Review street frontage, parcel shape and nearby parcel numbers.
Recorded maps, deeds, easements and a licensed surveyor control when legal boundaries matter.
How to Look Up an LA County Property-Tax Bill
Verify the property address and parcel before opening the tax system.
Use the Treasurer and Tax Collector’s property-tax service rather than a third-party payment advertisement.
Annual, supplemental, adjusted and prior-year bills may appear separately.
A recently purchased or improved property may have both an annual bill and one or more supplemental bills.
Confirm whether each installment is unpaid, paid, delinquent or handled through mortgage escrow.
Keep the bill with the closing statement, escrow records and payment confirmations.

LA County Assessment Appeal Deadlines and Fee
| Assessment Type | Filing Period | What Controls |
|---|---|---|
| Regular annual assessment | July 2 through November 30 | The annual Assessment Appeals Board filing window. |
| Supplemental assessment | Within 60 days after mailing | Notice date or postmark, as described by the official rules. |
| Adjusted or escape assessment | Within 60 days after mailing | The specific notice or adjusted bill. |
| Misfortune or calamity reassessment | Within six months after the proposed reassessment notice | The mailing date of the Assessor’s proposed reassessment. |

The mailing date can determine whether the appeal is timely.
One property owner can receive several notices for different parcels or events.
Possible issues include market value, decline in value, new construction, change in ownership or incorrect property data.

Keep the application, attachments, receipt and every hearing notice.
How to Request an LA County Deed, Lien or Recorded Document
Los Angeles County real-estate records dating back to 1850 can be searched and requested by members of the public. However, the Recorder does not provide unrestricted online access to its real-estate indexes or document images.
Prepare the AIN, street address, legal description and approximate recording date.
Examples include grant deed, quitclaim deed, deed of trust, reconveyance, lien, release, easement or notice.
Use the grantor and grantee names shown in the transaction or title documents.
The Recorder provides online request, in-person, fax and mail options.
A matching name or address alone does not prove that a document belongs to the intended parcel.
A certified copy may be required for court, lender, title, probate or other official use.
