Where to Search Los Angeles County Property Records
Los Angeles County does not put every property document into one public search system. Selecting the right office is the fastest way to find the correct information.
Office of the Assessor
Use this office for parcel identification, assessment information, property characteristics, and map-based property lookup.
Search Assessor records ↗Treasurer and Tax Collector
Use the county tax system to review secured property tax bills, outstanding amounts, and payment history where available.
Open Tax Collector ↗Registrar-Recorder/County Clerk
Request recorded deeds and other real estate documents. Online public browsing of the complete recorder index is not offered.
Request recorded records ↗How to Search Property by Address in Los Angeles County
You can begin with a street address even if you do not know the parcel number. The official Assessor Portal supports basic searches by address or AIN.
Open the Assessor Portal
Go to Los Angeles County Assessor Basic Search. This is the county-operated property assessment system, not a private listing database.
Enter the property address
Search using the known street address. If the address is incomplete or recently changed, try the AIN instead. Use the address associated with the property’s county assessment record.
Select the matching parcel
Check the returned parcel information carefully, especially for condominiums, apartment buildings, commercial properties, and parcels with similar street addresses.
Review the available assessment details
Look for the AIN, situs or property location, assessed values, and available characteristics. Record availability and fields can differ by property.
Continue to the appropriate office
Use the AIN to locate tax information. If you need a recorded deed, title document, or official certified copy, continue to the Registrar-Recorder’s records request process.
Los Angeles County AIN and APN: What the Parcel Number Means
Los Angeles County uses a 10-digit Assessor’s Identification Number (AIN) for real property. The AIN is also commonly called the Assessor’s Parcel Number (APN).
Example Parcel Number
1234-567-890
Map book number
Map page number
Parcel number
Illustrative number only; not a real property lookup result.
Where to Find Your AIN
- On an annual secured property tax bill.
- On a supplemental property tax bill.
- On certain deed or title documents.
- Through the Assessor Portal using the property address.
- By contacting the Assessor if the number cannot be located.
For newly built properties or recently subdivided parcels, a separate tax parcel may not have been created or fully reflected in the system yet. Contact the Assessor when a new property is missing or the parcel description is unclear.
What Information Can a Los Angeles County Property Search Show?
The type of record you can access depends on the department and the parcel. Public assessment records, tax payment records, and legal recording documents serve different purposes.
| Record Type | Typical Information | Official Source |
|---|---|---|
| Parcel identification | AIN/APN and property location identifiers. | County Assessor |
| Assessed values | Assessment information used for the property tax roll. | County Assessor |
| Property characteristics | Available land and improvement details from assessor records. | County Assessor |
| Tax bills | Secured tax charges, installments, and outstanding amounts. | Treasurer and Tax Collector |
| Payment history | Available secured property tax payment records. | Treasurer and Tax Collector |
| Parcel maps | Parcel location and approximate mapped boundaries. | Assessor map resources |
| Recorded deeds | Recorded conveyance documents and other real estate instruments. | Registrar-Recorder |
Los Angeles County Property Tax Search and 2026 Payment Dates
Once you have the property’s AIN, the County Property Tax Portal is the appropriate starting point for tax bills and secured tax information. You can also access billing and payment services through the Treasurer and Tax Collector’s website.
Annual Secured Property Tax Deadlines
The county’s annual secured property tax bill is divided into two installments. The dates below are the standard California secured property tax schedule used by Los Angeles County.
| Installment | Due Date | Standard Delinquency Date |
|---|---|---|
| First installment | November 1 | December 10 |
| Second installment | February 1 | April 10 |
For the 2026–27 fiscal tax year, the standard installment due dates are November 1, 2026, and February 1, 2027. The standard delinquency dates are December 10, 2026, and April 10, 2027, subject to applicable weekend or holiday extensions. Verify the exact deadline printed on your bill.
Supplemental, escape, adjusted, and unsecured tax bills can follow different timelines. Do not assume that an annual secured tax deadline applies to every tax notice.
What Happens When Property Taxes Are Late?
The Treasurer and Tax Collector generally applies a 10% penalty to an unpaid installment after the applicable delinquency deadline. The second installment can also incur a notice cost. Unpaid taxes remaining after the fiscal year may become tax-defaulted and subject to additional charges.
Check the official tax account for the exact amount due instead of estimating penalties from the original bill.
How to Read a Property Tax Bill
Look for the assessment number, tax year, installment amounts, special assessments, and payment deadlines. The bill can include a general property tax levy, voter-approved indebtedness, and direct assessments for services or local districts.
Los Angeles County GIS and Parcel Map Search
Parcel maps help identify the geographic location of land and how a parcel relates to surrounding parcels. The Los Angeles County Assessor Portal includes a map-search option alongside its basic and legal search tools.
Assessor Map Search
Begin with the official map-search feature to locate a property visually and relate it to assessor parcel information.
Open Assessor Map Search ↗Check Parcel Details
Compare the mapped parcel with the AIN and situs address. For subdivisions, condominiums, or unusual lot configurations, verify the legal description when necessary.
Visit County Assessor ↗How to Use a Parcel Map
Find the correct AIN
Search the street address in the assessor’s basic search tool and identify the matching parcel.
Open the map view
Use the Assessor Portal’s map-search feature and locate the property.
Compare location and boundaries
Review nearby parcels, street location, and the parcel identifier before relying on the map.
Verify legal boundary questions separately
An online assessor map is not a substitute for a recorded survey, parcel map, or professional boundary determination.
How to Find Property Owners, Deeds and Recorded Documents
Many visitors searching for Los Angeles County property records are trying to identify an owner or obtain a deed. The key distinction is that the Assessor and Registrar-Recorder maintain different kinds of records.
The Registrar-Recorder/County Clerk maintains recorded real estate records dating back to 1850. The county confirms that members of the public can request those records, but its real estate records and indexes are not available for open online searching.
Requesting a Recorded Deed
Identify the property and available transaction details
Start with the address and AIN. For a Recorder request, gather the grantor and grantee names and approximate year of recording when known.
Use the Registrar-Recorder’s records request instructions
The county provides instructions for requesting recorded real estate documents online, in person, by mail, or through other listed request methods.
Choose a plain or certified copy
A plain copy may be sufficient for personal research. If another institution requires an official certified copy, confirm that requirement before ordering.
Pay the applicable request fee
Fees depend on the document, number of pages, and request method. Check the county’s current fee schedule before submitting an order.
If you need verified current ownership for a legal transaction, consider obtaining an appropriate title report or advice from a qualified California real estate professional. Assessment data alone may not show every interest affecting title.
Los Angeles County Property Record Copy Fees
The Assessor’s public online lookup and a formal Recorder document-copy request are different services. The county publishes specific fees for copies of recorded real estate documents.
| Document or Service | Published Fee | Details |
|---|---|---|
| Plain copy, first page | $5 | Recorded real estate document copy. |
| Plain copy, additional page | $3 | Each additional page. |
| Certified copy, first page | $6 | Official certified document copy. |
| Certified copy, additional page | $3 | Each additional page. |
| Mail search fee | $0.50 | Per name, per year; $1 minimum. |
These are published Recorder copy/search fees, not a general charge for using the Assessor’s property lookup. Online orders, delivery, handling, payment processing, or expedited service can introduce additional charges.
Property Assessed Value, Market Value and Assessment Appeals
The assessed value in county records helps determine property taxes under California’s assessment system. It should not be read as a live estimate of the home’s likely sale price.
Assessed Value
A value maintained for property tax assessment purposes, subject to applicable California law, reassessment events, and exemptions.
Market Value
The price a property might command under current market conditions. It can differ from the assessment shown in public records.
What If Your Assessment Appears Too High?
First, review the parcel’s characteristics and assessed value. If the record contains an error in land or building data, the Assessor provides a Property Data Change Request process.
For a formal assessment appeal, the Los Angeles County Assessment Appeals Board handles applications challenging eligible assessments.
| Appeal Type | Published Filing Period |
|---|---|
| Regular assessment | July 2 through November 30 |
| Supplemental assessment | Generally within 60 days of the applicable notice or bill mailing/postmark date, as defined by the county. |
| Adjusted or escape assessment | Generally within 60 days under the county’s applicable notice rules. |
The county lists a $46 nonrefundable assessment appeal application fee, with a financial-hardship waiver request process available for eligible applicants. Filing an appeal does not automatically suspend your property tax payment obligations.
2026 Decline-in-Value Review
The Assessor announced that decline-in-value applications for the 2026–27 tax year opened July 2, 2026, with a November 30, 2026 deadline. An Assessor decline-in-value review and a formal Assessment Appeals Board application are separate processes, so use the instructions for the option that fits your situation.
Check the Assessor’s current decline-in-value instructions before filing.

Frequently Asked Questions
Can I search Los Angeles County property records for free?
Yes. You can access the official Assessor Portal to look up available property assessment information by address or AIN without paying a document-copy fee. Certified deeds and some other official records require payment.
How do I find a Los Angeles County parcel number by address?
Open the Assessor Portal, search the street address, and identify the matching property. The record’s 10-digit AIN is the parcel identifier used by county assessment and tax services.
Can I look up Los Angeles County property ownership online?
You can begin with the county’s available assessor information, but it should not be treated as a complete title investigation. Recorded deeds and related ownership instruments are handled by the Registrar-Recorder, which does not provide an openly searchable online real estate record index.
Where can I check whether property taxes have been paid?
Use the County Property Tax Portal or the Treasurer and Tax Collector’s website. Enter the AIN and select the appropriate secured property tax service. Online payment history may have limitations for adjusted or corrected accounts.

In Los Angeles County, AIN means Assessor’s Identification Number and is commonly used interchangeably with APN, or Assessor’s Parcel Number. The identifier consists of 10 digits representing the map book, map page, and parcel.
Are parcel maps legally accurate property surveys?
No. Assessor parcel maps and GIS data help locate and identify property, but they do not replace a professional boundary survey or the underlying legally recorded documents.

The Registrar-Recorder lists $5 for the first page of a plain copy and $6 for the first page of a certified copy, with $3 per additional page. Other charges can apply depending on the request method.

Yes, eligible property owners can pursue the appropriate assessor review or formal assessment appeal process. The regular appeal filing window is July 2 through November 30. Separate timing rules apply to certain other assessments.
