Los Angeles County Property Records
Search by Address, AIN, Assessor Map, Tax Bill and Recorded Documents
Use the official Los Angeles County Assessor Portal to search property records by address or Assessor Identification Number (AIN). This guide also explains where to find your secured property tax bill, payment balance, map search, Homeowners’ Exemption, decline-in-value review, assessment appeal, and real estate records through the correct county offices.
Use the official Los Angeles County Assessor Portal to search by AIN or property address. Use Assessor Map Search when you need parcel map context. Use the Treasurer and Tax Collector for tax bills and payments. Use the Registrar-Recorder/County Clerk for recorded real estate documents.
What Should You Click First for a Los Angeles County Assessor Property Search?
Los Angeles County property research is split across multiple official offices. The Assessor values property and maintains assessment records. The Treasurer and Tax Collector handles tax bills and payments. The Registrar-Recorder/County Clerk handles recorded real estate documents.
I have a property address
Use the LA County Assessor Portal and search by address. This is the best first step for homeowners, buyers, agents, renters verifying a parcel, and people who do not know the AIN yet.
Open Assessor PortalI have the AIN
Search by Assessor Identification Number. AIN is the strongest identifier when you need tax bill lookup, map search, ownership/assessment context, or payment information.
Search by AINI need the tax bill or payment balance
Use the Treasurer and Tax Collector property tax services. You usually need AIN, year, and sequence details from your secured tax bill for payments.
Open TTC tax servicesI need parcel map context
Use Assessor Map Search for assessor parcels, reference layers, cities, communities, ZIP Codes, school districts, supervisorial districts and map orientation.
Open Map SearchI disagree with assessed value
Start with LA County Assessor decline-in-value or contest-assessment information, then file an Assessment Appeals application if needed and on time.
Open contest assessment helpI need deed or ownership history
Use the Registrar-Recorder/County Clerk for real estate records. Assessor data is useful for parcel identity, but recorded documents are the legal record route.
Open Recorder pageLos Angeles County Assessor Property Search by Address — Step-by-Step Guide
For most users, the fastest way to find an LA County property record is to start with the official Assessor Portal and search by address. Once the correct parcel opens, save the AIN because it is used across tax, map, payment and many property-record workflows.
Open the official LA County Assessor Portal
Go to https://portal.assessor.lacounty.gov/. The portal supports search by AIN or address and is the best starting point for official assessor records.
Enter the property address carefully
Use the street number and street name first. If the search fails, remove apartment/unit details, punctuation, city name, ZIP Code, and street suffix. Los Angeles County has many cities and communities, so address formatting matters.
Choose the matching property result
Verify the city/community, parcel map context, and address before opening the result. A single street name can appear in multiple cities or unincorporated areas.
Save the AIN
The Assessor Identification Number is the key identifier for LA County property tax and assessment tasks. Save it before you move to the tax portal, map search, exemption forms, appeal pages or recorded document research.
Use map search if the address is confusing
If the address search returns too many results or no result, use Assessor Map Search. It helps with condominiums, hillside parcels, vacant land, long street names, unincorporated areas and parcels near city boundaries.
Search tip that fixes many no-result searches: Type less, not more. Search the street name and number first. If that fails, remove “Street,” “Avenue,” “Boulevard,” “Road,” apartment/unit numbers, punctuation and ZIP Code. Then confirm the AIN through the official result.
Los Angeles County AIN Search — Assessor Identification Number, Parcel Map and Tax Bill
The AIN is the most important Los Angeles County property identifier. It is commonly shown as a 10-digit Assessor Identification Number and may be connected to the assessor map book, page and parcel structure.
Where to find your Los Angeles County AIN
Assessor Portal
Search by address first, then copy the AIN from the property result.
Secured tax bill
Your annual secured property tax bill shows AIN and payment-related identifiers.
Assessor Map Search
Use map search to click or locate the parcel and confirm the AIN.
Recorded document clue
Some real estate documents may reference AIN or legal description details.
Escrow paperwork
Closing papers or title documents may include parcel/AIN information.
Property Tax Portal
Use AIN with year/sequence details for payment-related tasks.
AIN vs APN: Many people call it APN, parcel number or assessor parcel number. Los Angeles County commonly uses AIN, Assessor Identification Number. For tax-payment tasks, use the exact AIN and bill details shown by the county.
Can You Search Los Angeles County Property Records by Owner Name?
Do not expect the LA County Assessor Portal to work like a people-search website. The official Assessor Portal is focused on AIN and address search. If your real goal is owner history, deed research or title chain, use the Registrar-Recorder/County Clerk real estate records path.
Best route if you know the address
Search the address in the Assessor Portal first. Then save the AIN and property details. This is faster and safer than guessing owner names.
Best route if you know only a name
Real estate records in Los Angeles County are maintained in alphabetical indexes by name and year recorded. Use Registrar-Recorder/County Clerk resources for recorded documents.
Recent sale warning
Assessor, tax and recorder data may update on different cycles. If a sale recently closed, compare the property assessment record with recorded document information before assuming the county data is wrong.
Commercial-use caution
Do not scrape public property records or use property information as a consumer report. For employment, tenant screening, credit or eligibility decisions, use legally compliant sources and professional advice.
Need recorded real estate documents? Start with the official Registrar-Recorder/County Clerk recorder page.
Open Recorder PageWhat Shows in a Los Angeles County Assessor Property Record
The Assessor record helps you identify the property and understand assessment information. For tax-payment balance, use the Treasurer and Tax Collector. For deeds and recorded documents, use the Registrar-Recorder/County Clerk.
AIN
Assessor Identification Number used across LA County property systems.
Property address
Address tied to the assessor parcel and assessment roll.
Assessed value
Value information used in the property tax process.
Property characteristics
Land, improvement and property-description details where available.
Parcel map
Assessor parcel map and reference layer context.
Exemption status
Homeowners’ Exemption and other assessment-related relief clues.
Tax bill route
Use AIN with TTC property tax services for bill and payment tasks.
Recorded document route
Use RR/CC for deeds, real estate records and recorded-property documents.
Do not treat the Assessor record as a title report: Assessor data is not a deed, title insurance report, boundary survey, permit approval or legal ownership opinion. Use the Recorder, title company, surveyor or legal professional when your decision depends on legal ownership, liens, easements or boundaries.
Los Angeles County Property Tax Records — Tax Bill, Balance, Payment and Due Dates
Use the Assessor to identify the property and value. Use the Los Angeles County Treasurer and Tax Collector for property tax bills, payment balances, payment history, installment plans and payment options.
View tax bill and balance
Use the Los Angeles County property tax services to view annual secured property tax bills, property tax balance due, payment history and related tax services.
Open TTC property tax servicesPay online with AIN
For online payments, LA County TTC says you need the Assessor’s Identification Number printed on your secured property tax bill. Card payments may include service fees.
Open payment optionsAnnual secured due dates
The first installment is due November 1 and delinquent after December 10. The second installment is due February 1 and delinquent after April 10.
Phone payment route
LA County TTC lists telephone card payment through 1-888-473-0835. You need AIN, year and sequence information from your secured property tax bill.
Payment mistake to avoid: Do not use the Assessor Portal as if it is the tax payment portal. The Assessor identifies and values the property. The Treasurer and Tax Collector receives property tax payments and handles balance/payment questions.
Los Angeles County Assessor Map Search — Parcel Layers, Cities, ZIP Codes and District Context
Use Assessor Map Search when a text search is not enough. It helps with parcel context, city/community boundaries, ZIP Codes, school districts, supervisorial districts and other reference layers.
Open map search
Use the official Assessor Map Search at https://portal.assessor.lacounty.gov/mapsearch.
Use map when address fails
Map search is useful for vacant land, hillside lots, condominiums, large parcels, unincorporated areas and parcels near city boundaries.
Reference layers
Assessor Map Search includes reference layers such as assessor parcels, cities, communities, ZIP Codes, school districts and supervisorial districts.
Map limitation
Map layers are not a legal boundary survey. Use recorded maps, title documents and licensed survey help for legal boundary decisions.
Los Angeles County Property Assessment Appeal — Decline in Value, Proposition 8 and Formal Appeal
If you disagree with your assessed value, start with the Assessor’s contest-assessment and decline-in-value resources. If needed, preserve your rights by filing a formal Assessment Appeals application during the correct filing period.
Check the Assessor record first
Verify AIN, address, property characteristics, assessed value and recent changes. Look for factual errors before filing a formal appeal.
Understand decline in value
LA County’s annual Decline-in-Value filing period is July 2 through November 30. This route is commonly connected with Proposition 8 temporary reductions when market value falls below the adjusted base-year value.
Collect evidence
Use comparable sales, appraisal reports, photos, repair estimates, incorrect property data and market evidence. A high tax bill alone is not the same as proof that the assessed value is wrong.
File formal appeal if needed
For the regular assessment roll, LA County Assessor guidance states that a formal appeal may be filed from July 2 through November 30. If the final date falls on a weekend or legal holiday, verify the current official rule.
Do not wait for tax payment deadlines
Assessment appeal deadlines and tax payment deadlines are different. Paying the tax bill does not automatically file an appeal, and filing an appeal does not automatically pause your tax-payment obligations.
Need assessment contest help? Open the official LA County Assessor contest-assessment page first.
Open Contest AssessmentLos Angeles County Homeowners’ Exemption — $7,000 Assessed Value Reduction and Filing Help
If you own a home and it is your principal place of residence on January 1, you may apply for a Homeowners’ Exemption. LA County Assessor guidance states the exemption is $7,000 from assessed value.
Who should check this
New homeowners, inherited-property owners, people who changed residence, and people unsure whether the exemption is already on file should check the official Assessor exemption route.
Open Homeowners’ ExemptionImportant full-benefit deadline
California BOE guidance says first-time claimants should file no later than February 15 to receive the full exemption for that year.
Do not file every year if approved
Once approved, a Homeowners’ Exemption generally remains on file, but you must notify the Assessor if the property is no longer eligible.
Do not pay third-party mailers blindly
Use official Assessor forms and online filing routes. Many exemption tasks can be handled directly with the official county office.
Need the official exemption route? Use the LA County Assessor Homeowners’ Exemption page or forms page.

Common Problems When Searching Los Angeles County Property Records
Most LA County property search problems happen because the user has the wrong office, wrong address format, no AIN, or expects owner/deed history from the Assessor Portal.
Address search gives no result
Remove apartment/unit, ZIP, punctuation, direction and suffix. Search street number plus street name only. Then use map search if needed.
You cannot find owner-name search
Use address or AIN in the Assessor Portal. For deed and ownership history research, use Registrar-Recorder/County Clerk real estate records.
Tax payment screen asks for AIN, year and sequence
Find the AIN through the Assessor Portal or your secured property tax bill. The year and sequence are payment identifiers tied to the tax bill.
Map line does not match a fence or wall
Assessor map layers are not legal surveys. Use recorded maps, title work and a licensed surveyor for boundary disputes.
A private site appears before the official site
Skip private aggregators for official decisions. Use assessor.lacounty.gov, portal.assessor.lacounty.gov, ttc.lacounty.gov and lavote.gov recorder pages first.
