Los Angeles Property Records Search | Deeds & Tax 2026

Official Los Angeles Property Record Sources

Los Angeles property records are not kept in one single public search box. The Assessor identifies and values property. The Treasurer and Tax Collector handles property tax bill and payment functions. The Registrar-Recorder/County Clerk maintains recorded real estate records. The Property Tax Portal explains how the Assessor, Auditor-Controller, Tax Collector and Assessment Appeals Board fit together.

Los Angeles Property Records Free Lookup: Step-by-Step

The cleanest free lookup starts with the Assessor because the AIN connects many Los Angeles County property systems. After you identify the correct property, use the tax system for bills and payment history, and use Recorder records for deeds or recorded document copies.

1. Open the Assessor Portal first. Go to the official LA County Assessor Portal and search by AIN or address.
2. Confirm the correct property. Match property address, AIN, city/community, map book/page/parcel style identifier and assessment details before relying on the result.
3. Use map search if the address is unclear. Open Assessor Map Search to review parcel and map context.
4. Check property tax bill or payment history separately. Use LA County Treasurer and Tax Collector to view property tax bills, pay taxes or view payment history.
5. Use Recorder records for deeds and legal documents. Open LA County Real Estate Records when you need deeds, mortgages, liens, copies or recorded document research.

AIN, APN, Owner and Address Search Tips

Los Angeles County commonly uses the Assessor’s Identification Number, or AIN. The county property tax statement explains that the AIN is a ten-digit number assigned by the Assessor to each piece of real property. It is made up of a four-digit map book number, a three-digit page number and a three-digit parcel number.

LA County Assessor Records, Maps and Assessed Value

The LA County Assessor is the correct office for assessed value, property characteristics, exemption-related assessment items, mailing address changes and parcel identification. Use the Assessor Portal when your main question is “what property is this?” or “what does the county assessment record show?”

1. Open the Assessor property search. Use the official LA County Assessor Property Search page or the Assessor Portal.
2. Search by AIN or address. Enter the AIN exactly if you have it. For address search, use the property address and then verify the city/community.
3. Review the assessment record. Check AIN, situs address, assessed values, property characteristics and available assessment details.
4. Use Assessor Map Search for parcel context. Open Map Search if you need assessor map context.
5. Contact Assessor for assessment questions. Use Contact the Assessor for office guidance, phone support and official communication paths.

Property Tax Bills, Payment History and Treasurer-Tax Collector Records

Use the LA County Treasurer and Tax Collector when you need to view a secured property tax bill, pay property taxes, view payment history or submit a public inquiry. The Tax Collector’s payment pages explain that you need your Assessor’s Identification Number to complete many property tax payment tasks.

1. Open the Treasurer and Tax Collector website. Visit LA County Treasurer and Tax Collector.
2. View the property tax bill. Use the official “View Property Tax Bill” path on the Treasurer and Tax Collector website.
3. Check payment history. Open Property Tax Payment History and use your AIN where required.
4. Pay only after verifying the bill. Use Payment Options and confirm AIN, tax year, installment, amount due and deadline before paying.
5. Save confirmation proof. Keep payment confirmation number, screenshots, receipts, bank proof and mailed-payment postmark evidence.

Los Angeles Deeds, Mortgages, Liens and Real Estate Records

The LA County Registrar-Recorder/County Clerk maintains real estate records after they are filed with the Property Document Recording section. Use this office when your search intent is deed lookup, mortgage/deed of trust copy, lien, reconveyance, notice of default, document copy or recorded real estate record research.

1. Open real estate records guidance. Visit LA County Real Estate Records.
2. Review viewing options. Use View Real Estate Records for in-person viewing and record-location guidance.
3. Request copies if needed. Use Online Request for copy-request instructions.
4. Use the right search clues. Prepare owner names, grantor/grantee names, document type, recording year, document number, legal description or AIN if available.
5. Compare with the Assessor record. Use the Assessor Portal to compare AIN and property address before relying on a recorded document.

Real Estate Record Copies and In-Person Viewing

Los Angeles County real estate records are available after filing with the Recorder. The county states that records can be purchased in person, online or by mail. For older records, in-person viewing at the Recorder’s Norwalk headquarters may be needed.

Assessor Maps, Parcel Maps and GIS Cautions

Assessor Map Search is useful when you need map book, page, parcel context, nearby parcels, cities, communities, ZIP codes, school districts or parcel map layers. It is especially helpful in Los Angeles County because the same street name can appear in different cities or unincorporated communities.

1. Open Assessor Map Search. Use LA County Assessor Map Search.
2. Search by AIN or address. Use the AIN when available. If searching by address, confirm the city/community.
3. Review parcel and reference layers. Use assessor parcel layers and reference layers to confirm you are viewing the correct parcel.
4. Compare with the tax bill. Use Treasurer and Tax Collector tools to compare the AIN and tax bill.
5. Use legal records for boundary decisions. Do not rely on online map lines as final proof for fences, easements, setback disputes or title issues.

Assessment Appeals, Value Review and Record Corrections

If your Los Angeles property value, exemption status, mailing address, AIN details or tax bill appears wrong, identify which office controls the problem. The Assessor handles assessed value and assessment roll data. The Treasurer and Tax Collector handles bills and payments. The Registrar-Recorder handles recorded documents. The Assessment Appeals Board handles formal assessment appeal matters.

1. Review the Assessor record first. Search the property through the Assessor Portal.
2. Review the property tax bill. Use Treasurer and Tax Collector to view the current bill and payment details.
3. Use the Property Tax Portal for process questions. Open LA County Property Tax Portal for explanations of county property tax roles.
4. Collect evidence. Useful support may include comparable sales, photos, appraisal reports, damage documentation, closing statements, deed records, exemption forms and prior tax bills.
5. Contact the correct office. Use Assessor contact paths for assessment issues, Tax Collector contact paths for payment issues and Recorder paths for recorded document issues.
