LA County Property Records
Search by Address, AIN/APN, Tax Bill, Parcel Map and Recorder Records
LA County assessor property search starts with the official Los Angeles County Assessor Portal. This guide shows you how to find Los Angeles County property records on official county websites for free, including assessed value, AIN/APN, parcel map, property tax bill, payment history, Homeowners’ Exemption, Proposition 13 and Proposition 19 basics, decline-in-value review, and deed-record routes.
Use the official Los Angeles County Assessor Portal at https://portal.assessor.lacounty.gov/. The portal’s basic search is built around AIN/APN or property address. Use the LA County Property Tax Portal or Treasurer and Tax Collector website for tax bills and payment history. Use the Registrar-Recorder/County Clerk for deed and real estate recording records. This guide is only a directory; it does not store LA County property records.
What Should You Click First for an LA County Assessor Property Search?
The fastest LA County property lookup path depends on what you already have. Use the Assessor Portal first for AIN/APN or address, then use the tax portal, parcel map, Recorder records or appeal pages only when your question requires it.
I have a property address
Open the LA County Assessor Portal and use Basic Search. Start with the street address, then simplify the address if no result appears.
Open official address searchI have an AIN / APN
Use the Assessor’s Identification Number for the cleanest match. LA County commonly uses AIN; many users also call it APN.
Open AIN searchI need tax bill or payment history
Use LA County Treasurer and Tax Collector or the county Property Tax Portal. The Assessor does not collect property tax payments.
Open tax collector siteI need a deed or recorded document
Use the LA County Registrar-Recorder/County Clerk. Real estate records are recorded there, not in the Assessor Portal.
Open Recorder pageI disagree with assessed value
Use the decline-in-value review, contest assessment guidance, or Assessment Appeals Board depending on the notice type and filing window.
Open Appeals BoardI need a parcel map
Use Map Search for parcel boundaries, reference layers, cities, communities, ZIP codes and assessment map context.
Open map searchLA County Assessor Property Search by Address — Step-by-Step Guide
This guide shows you how to find LA County property records on the official Los Angeles County Assessor website for free. For most homeowners, buyers, renters and neighbors, the address search is the easiest starting point.
Open the official LA County Assessor Portal
Go to https://portal.assessor.lacounty.gov/. Use the county portal, not a paid people-search site or private property aggregator.
Use Basic Search for address
Enter the property address in the cleanest format possible. Start with house number and street name. Avoid long pasted addresses with ZIP code, county name, state and extra punctuation.
Shorten the address if the search fails
If the exact address fails, remove unit number, directional prefix, street suffix and city name. Try only the street name or the house number plus street name. This is especially useful for condos, apartments, hillsides, unincorporated areas and properties near city boundaries.
Open the matching property result
Once the correct property opens, save the AIN/APN. The AIN is the most reliable identifier for tax bills, parcel maps, appeal paperwork, recorded document searches and future lookup.
Move to the right county office
Use the Assessor for assessed value and property details, Treasurer and Tax Collector for bills and payments, Registrar-Recorder for deeds, and Assessment Appeals Board for formal appeals.
Most people miss this: if the address search returns zero results, remove the directional prefix such as N/S/E/W and the street suffix such as St/Ave/Blvd. Type only the street name. This fixes many address-search failures in county portals.
How to Search LA County Property Records by Owner Name
LA County owner-name research usually belongs in recorded real estate records, not the basic Assessor Portal. The Assessor Portal is strongest for AIN/APN and address. For owner history, deed transfers, grantor/grantee names and recorded document context, use the Registrar-Recorder/County Clerk route.
Best route if you know the address
Search the address in the Assessor Portal first. Copy the AIN/APN from the property result. Then use the AIN/APN when researching tax bills, maps or recorded document history.
Best route if you know only a name
Use the LA County Registrar-Recorder real estate record resources. Los Angeles County real estate records are maintained in alphabetical indexes by name and year recorded.
Recent sale looks outdated
Assessment, tax and recorded document systems can update on different schedules. If you see a prior owner or old value, confirm the recorded deed and allow for processing time.
Private owner websites are not official
Skip paid people-search sites for basic verification. Use LA County official Assessor, Treasurer and Recorder resources first, then decide whether a paid copy service is actually needed.
Privacy and use warning: LA County property and recording records are public records, but public access does not mean the information should be scraped, resold, harassed or used unlawfully. Use official records for property, tax, title and valuation research.
LA County Parcel ID Lookup — AIN, APN and Assessor’s Identification Number Search
LA County commonly uses the term AIN, meaning Assessor’s Identification Number. Many homeowners and real estate users call it APN, meaning Assessor’s Parcel Number. For practical searching, treat AIN/APN as the key parcel identifier.
Where to find your LA County AIN/APN
Property tax bill
Your secured property tax bill normally shows the AIN.
Assessor Portal
Search by address once, then save the AIN from the result.
Recorded deed
Recorded documents may include parcel identifiers or legal description clues.
Parcel map
Use Map Search to confirm parcel location and reference layers.
Escrow paperwork
Closing documents and title files often list APN/AIN.
Supplemental bill
After a sale or new construction, supplemental tax documents use the AIN.
Practical rule: search by address only until you find the AIN. After that, use the AIN for tax bills, payment history, parcel map, assessment appeal and Recorder-index research. It reduces confusion in a county with millions of parcels.
What Shows in an LA County Property Record
An LA County property record can show assessment and parcel information, but it is not the same as a tax receipt, grant deed, title report, survey, building permit or zoning decision. Use the correct county office for each record type.
AIN / APN
The parcel identifier used across assessor, tax and map systems.
Property address
The address tied to the assessed parcel or property result.
Assessed value
Values used for property tax assessment under California rules.
Roll details
Assessment roll information and value fields where available.
Tax bill route
Use the tax portal or Treasurer website for bill amount and payments.
Map context
Use Map Search for parcels, cities, communities and reference layers.
Exemption clue
Homeowners’ Exemption and other relief may affect taxable value.
Recorder route
Use the Registrar-Recorder for deeds and real estate documents.
Do not treat the portal as a title report: the Assessor Portal helps with assessed value and parcel lookup. For ownership transfers, liens, deeds or title due diligence, use the Registrar-Recorder and a qualified title professional when needed.
LA County Property Tax Records — Assessed Value, Tax Bill and Payment
The LA County Assessor establishes assessed values, while the Treasurer and Tax Collector handles property tax bills, payments and payment history. Do not use the Assessor Portal when your real question is “How much do I owe?” or “Was my payment received?”
Assessed value question
Use the Assessor if your question is about assessed value, AIN, property information, exemptions, Prop 13, Prop 19 or decline-in-value review.
Tax bill question
Use the LA County Treasurer and Tax Collector for secured property tax bills, payment options, bill viewing, payment history and penalties.
Property Tax Portal route
The LA County Property Tax Portal connects the Assessor, Auditor-Controller, Treasurer and Tax Collector, and Assessment Appeals Board roles.
AIN required for tax lookup
The tax portal often asks for the Assessor’s Identification Number. Search the Assessor Portal by address first if you do not know the AIN.
LA County payment timing reminder: secured property tax bills usually follow the California two-installment schedule. The first installment is due November 1 and becomes delinquent after December 10. The second installment is due February 1 and becomes delinquent after April 10. Always verify your own bill on the official LA County tax site.
Need to view or pay a tax bill? Use the LA County Treasurer and Tax Collector website or the Property Tax Portal.
Open Tax Collector SiteLA County GIS Parcel Map and Assessor Map Search — How to Access
Use LA County Assessor Map Search when you need parcel boundaries, map context and reference layers. It is helpful for properties in Los Angeles, Long Beach, Santa Monica, Pasadena, Lancaster, Palmdale, Glendale, Torrance, unincorporated communities and hillside or multi-parcel areas.
Use it for parcel context
Map Search helps you see the parcel location and nearby parcel context after you identify the AIN/APN.
Use reference layers
The map portal includes reference layers such as assessor parcels, supervisorial districts, cities, communities, ZIP codes and school districts.
Use it for boundary clues
Map lines help with research, but they are not legal boundary surveys. Use recorded documents and professionals for legal boundary disputes.
Know the limit
Map Search is not a building permit, zoning approval, survey, title opinion or legal determination of property rights.
Need the parcel map? Open the official LA County Assessor Map Search.
Open Map SearchLA County Property Assessment Appeal — Decline in Value, Supplemental Assessments and Filing Periods
If you disagree with LA County’s assessed value, first identify what kind of assessment you are challenging. Regular assessment appeals, supplemental assessments, escape assessments and decline-in-value reviews follow different routes and deadlines.
Check the notice type first
Look at whether you received a regular annual value, supplemental assessment, adjusted supplemental bill or escaped assessment. The deadline depends on the notice type.
Use decline-in-value review when market value dropped
LA County’s Decline-in-Value Review Application is filed with the Assessor between July 2 and November 30 for the fiscal year beginning July 1.
Use Assessment Appeals Board for formal appeals
Regular assessment appeal filing dates are July 2 to November 30. Supplemental assessments generally have a 60-day filing period tied to the supplemental notice or tax bill mailing date.
Collect evidence before filing
Use comparable sales, incorrect property characteristics, condition photos, appraisal evidence and documents showing why the assessed value should be lower. “My tax bill is too high” is not strong evidence by itself.
Do not miss the deadline
LA County appeal deadlines are strict. If you have a supplemental or escape notice, count the deadline from the notice or tax bill details instead of waiting for the annual filing window.
Appeal shortcut: use the official LA County Assessment Appeals Board for formal appeals and the Assessor decline-in-value page for informal review.
Open Appeals BoardHomeowners’ Exemption in LA County — How to Apply and Save on Taxes
LA County homeowners who own and occupy a home as their principal place of residence on January 1 may apply for the California Homeowners’ Exemption. The exemption reduces assessed value by $7,000, which typically saves about $70 per year.
Who may qualify
You must own the home and use it as your principal place of residence on January 1. You cannot claim the same exemption on multiple primary residences.
Exemption amount
The Homeowners’ Exemption reduces assessed value by $7,000. It is not a $7,000 cash refund; it reduces taxable assessed value.
Full exemption deadline
California guidance lists February 15 as the regular filing deadline to receive the full exemption for that year.
Prop 19 transfer help
LA County also provides guidance for transferring assessed value under Proposition 19 for eligible homeowners. Read the official Assessor page before relying on any summary.
Apply through official forms only: use the LA County Assessor exemption page for the Homeowners’ Exemption and related tax relief programs.
Open Homeowners’ ExemptionLA County Assessor vs Treasurer vs Registrar-Recorder — Which Office Handles Your Property Question?
Most LA County property-search confusion happens because the user asks the right question at the wrong office. Assessment, tax collection, recording and appeals are separate functions.
LA County Assessor
Use for assessed value, AIN/APN, parcel lookup, property information, Homeowners’ Exemption, Prop 13, Prop 19, decline-in-value review and assessment questions. Phone: 213-974-3211.
Treasurer and Tax Collector
Use for secured tax bills, payment options, payment history, property tax balance, penalties, delinquency and installment payment questions.
Registrar-Recorder/County Clerk
Use for real estate records, deed copies, document recording, viewing recorded documents, grantor/grantee index routes and property document recording services.
Assessment Appeals Board
Use for formal assessment appeals after you understand the assessment type and deadline. Regular filing dates are July 2 through November 30.
Common Problems When Searching LA County Property Records
If the official LA County search is not showing what you expect, the problem is usually address formatting, wrong portal, AIN confusion, recent sale timing, missing deed route or city-versus-county confusion.
No address result appears
Remove unit number, ZIP code, city name, directional prefix and street suffix. Try only the street name or use the AIN from a tax bill.
Owner name search is confusing
Use the Recorder route for grantor/grantee and real estate records. Do not assume the basic Assessor Portal is an owner-name search engine.
Tax bill does not match assessed value
Assessed value is only one part of the tax bill. Tax rate, bonds, direct assessments, exemptions, penalties and payment status can change the amount due.
Recent sale still shows old information
Assessment, recording and tax systems may not update at the same time. Check the recorded document route and allow processing time after a purchase or transfer.
City of LA vs County of LA confusion
Property assessment and county tax billing are county-level issues. City portals may handle permits, business taxes, code, utilities or local services, but the Assessor and Treasurer are county offices.
LA County Assessor Office Location, Phone and Map
The LA County Assessor’s main office is at the Kenneth Hahn Hall of Administration in downtown Los Angeles. Always verify public access, appointments and department availability before visiting.
Los Angeles County Assessor — Kenneth Hahn Hall of Administration
500 W Temple Street, Room 225, Los Angeles, CA 90012
Assessor: Jeff Prang
Main phone: 213-974-3211
Address: 500 W Temple Street, Room 225, Los Angeles, CA 90012
