Los Angeles County, California Property Guide

Search Los Angeles County Property Records, Understand Assessments, Claim Exemptions, File Appeals and Pay the Correct Tax Bill

Use this guide to search a Los Angeles County parcel by property address or Assessor Identification Number, review land and improvement values, understand Proposition 13, check exemptions, file an assessment appeal, pay secured taxes and request recorded deeds or liens.

Los Angeles County does not operate a Texas-style County Appraisal District. The County Assessor values property, the Auditor-Controller calculates tax rates and extends taxes, the Treasurer and Tax Collector issues and collects bills, and the Assessment Appeals Board hears formal value disputes.

Independent guide — official county systems are used for the final search, filing, payment or recorded-document request.

Critical Corrections to the Existing Los Angeles County CAD Article

Previous Article Claim Correct Los Angeles County Information Why It Matters
Los Angeles County CAD or LACAD Los Angeles County Assessor California does not use the Texas appraisal-district structure.
Search by property owner name The main county search starts with a property address or 10-digit AIN. Public owner-name browsing is restricted and is not the standard parcel-search method.
May 15 protest deadline Regular assessment appeals are filed July 2 through November 30. May 15 is Texas terminology and does not control Los Angeles County appeals.
ARB hearing Formal appeals are heard through the Los Angeles County Assessment Appeals Board. Using the wrong office name can send taxpayers to an irrelevant process.
Property appeal is always free The Assessment Appeals Board currently charges a $46 filing fee, with a hardship-waiver process. Applicants should understand the filing cost before submitting.
April 30 exemption deadline California exemption filing periods depend on the exemption and tax year. The April 30 Texas deadline should not be applied to California claims.
Senior exemption and tax ceiling California does not provide a broad Texas-style senior exemption or school-tax ceiling. Eligible owners may instead need a Homeowners’ Exemption, Proposition 19 transfer or separate state postponement program.
One yearly tax deadline Annual secured taxes are paid in two installments. Each installment has its own due and delinquency date.
Do not retain Texas language in this article. Terms such as CAD, ARB, May 15 protest deadline and April 30 homestead deadline are not correct for Los Angeles County.

What Is a Los Angeles County AIN?

The Assessor Identification Number is a 10-digit number used to identify a Los Angeles County parcel. It is commonly displayed in a format similar to 1234-567-890.

First four digits Commonly identify the Assessor map book.
Next three digits Commonly identify the page within the map book.
Final three digits Commonly identify the parcel on the page.

Where to find the AIN

  • Annual secured property-tax bill
  • Supplemental tax bill
  • Los Angeles County Property Tax Portal
  • Assessor parcel record
  • Closing or title documents
  • Previous tax-payment receipt
AIN and payment PIN are different. The AIN identifies the parcel. The separate six-character alphanumeric PIN printed on a secured tax bill is a security code used for certain online payment functions.
Security warning: The Treasurer and Tax Collector does not disclose the bill’s payment PIN by telephone, email or fax. Do not post it publicly or share it with an unknown payment service.

How to Read a Los Angeles County Assessor Record

Record Field Plain-Language Meaning What to Check
AIN The county’s 10-digit parcel identifier. Use the same AIN for Assessor, tax, appeal and document research.
Situs address The physical location associated with the parcel. Unit, city and ZIP code.
Use code The Assessor’s classification of the property’s principal use. Residential, condominium, commercial, industrial, vacant or another use.
Land value The assessed value assigned to the land portion. Base-year history, transfers and parcel changes.
Improvement value The assessed value assigned to buildings and taxable improvements. New construction, additions, demolition and property characteristics.
Total assessed value The combined assessed land and improvement value before applicable exemptions. Compare it with notices, supplemental assessments and appeal decisions.
Year built The construction year shown in the assessment record. Original construction versus major additions or effective-age issues.
Building area The Assessor’s recorded building size. Permitted living area, additions, ADUs and excluded spaces.
Tax-rate area The combination of local taxing agencies serving the parcel. Nearby properties can belong to different tax-rate areas.
Legal description or map Recorded or mapped parcel-identification information. Use deeds, tract maps and surveys for legal decisions.
Public record limitation: An Assessor record is useful for taxation and research, but it does not replace a deed, title report, survey or legal ownership determination.

How to Use Los Angeles County Parcel Maps

Assessor maps can help identify parcel shape, adjoining parcels, map-book references and AIN relationships. They should not be treated as boundary surveys.

1
Search the parcel and copy the AIN.

Confirm the property address and parcel before opening a map.

2
Open the Assessor property or map portal.

Use the county-linked property-data and mapping tools rather than an unofficial parcel-map site.

3
Compare adjacent parcel numbers.

This is useful for properties with several lots, condominium common areas, parking parcels or adjoining land.

4
Review street, tract and parcel relationships.

Check whether the property contains one AIN or several separately assessed parcels.

5
Verify boundaries through legal documents.

Use recorded tract maps, parcel maps, deeds, easements and a licensed surveyor when exact boundaries matter.

Boundary warning: Do not place a fence, retaining wall, addition, driveway or utility improvement solely from an online Assessor map.
Final map action: Begin with the Los Angeles County Assessor Portal and use the parcel-data or map option connected to the verified AIN.

How Los Angeles County Property Assessments Work

California’s property-tax system differs substantially from a Texas market-value system. Proposition 13 generally establishes a base-year value when property changes ownership or new construction is completed.

Factored base-year value or current taxable value → minus exemptions → 1% general levy + voter-approved debt + direct assessments = annual tax bill
Base-year value Commonly established when property changes ownership or qualifying new construction is completed.
Annual inflation adjustment The factored base-year value generally increases by no more than 2% per year unless another reassessable event occurs.
Supplemental assessment A change in ownership or completed new construction can create a separate bill covering the portion of the fiscal year after the event.
Assessor Establishes assessed values, determines reassessable events and administers exemptions.
Auditor-Controller Applies the general levy, voter-approved rates and direct assessments to the certified value.
Treasurer and Tax Collector Issues bills, receives payments and administers delinquency and collection procedures.
The tax rate is not always exactly 1%. The bill can also include voter-approved debt and direct assessments for services, districts or local programs.

Change in Ownership and Supplemental Assessments

A sale, transfer, inheritance or ownership restructuring can trigger reassessment unless an exclusion applies. New construction can also create a supplemental assessment.

Event Possible Tax Effect What to Review
Purchase of property New base-year value based on the transfer. Purchase date, reported consideration and supplemental notice.
Transfer into or out of a legal entity May trigger reassessment depending on ownership and control changes. Entity documents and Assessor change-in-ownership forms.
Inheritance May qualify for a Proposition 19 exclusion or may be reassessed. Relationship, property use, value limits and filing requirements.
Addition or major construction New construction may be added to the existing base-year value. Completion date, permits and what portion is newly assessable.
ADU construction The new improvement may receive a separate new-construction value. Permitted area, completion date and recorded property data.
Disaster rebuilding Special rules can apply when qualifying property is reconstructed after damage. Damage records, replacement construction and current Assessor guidance.
Supplemental appeal deadline: A supplemental assessment generally must be appealed within 60 days after the notice was mailed. Do not wait for the regular July-to-November appeal period.

Los Angeles County Property-Tax Exemptions and Transfers

California exemptions usually reduce assessed value rather than subtracting the same dollar amount from the final bill. Eligibility, application periods and renewal rules vary by program.

Exemption or Program Who It May Help Important Detail
Homeowners’ Exemption An owner occupying the property as a principal residence. Reduces assessed value by up to $7,000; it does not reduce the tax bill by $7,000.
Disabled Veterans’ Exemption Qualifying disabled veterans and certain surviving spouses. Exemption amounts and income limits are adjusted periodically.
Proposition 19 base-year transfer Eligible homeowners age 55 or older, severely disabled homeowners and certain disaster victims. Can allow transfer of a qualifying base-year value to a replacement principal residence.
Parent-child or grandparent-grandchild exclusion Certain qualifying family transfers under Proposition 19. Principal-residence and value-limit requirements can apply.
Welfare Exemption Qualifying charitable, religious, hospital or scientific organizations. Ownership and actual property use must satisfy statutory requirements.
Church or Religious Exemption Qualifying property used for religious purposes. The correct annual or organizational claim must be filed.
Historical-property treatment Certain properties under qualifying preservation agreements. Eligibility depends on the applicable agreement and assessment rules.
Property-tax postponement Certain qualifying seniors, blind or disabled homeowners. This is generally a state postponement program, not a Los Angeles County senior exemption or permanent tax ceiling.

Homeowners’ Exemption checklist

  • Correct AIN
  • Property address
  • Owner’s legal name
  • Acquisition date
  • Principal-residence occupancy date
  • Mailing address
  • Government identification information requested by the form
  • Signed application and filing confirmation
Do not use April 30 as a Los Angeles County-wide exemption deadline. Check the current Assessor application for the applicable timely and late-filing rules.
Final exemption action: Review the Homeowners’ Exemption, Proposition 19 and other current Assessor programs before filing.

Decline-in-Value Review Under Proposition 8

A temporary decline-in-value assessment may apply when the property’s current market value falls below its factored base-year value. This is different from a permanent reduction in the Proposition 13 base-year value.

Temporary reduction The Assessor may enroll a lower market value for the affected assessment year.
Annual review A temporarily reduced property can be reviewed again in later years as market conditions change.
Base year remains The Proposition 13 factored base-year calculation generally continues in the background.

Evidence that may help

  • Comparable sales near the January 1 lien date
  • Property-condition photographs
  • Repair estimates
  • Professional appraisal
  • Location or access limitations
  • Market-data adjustments for size, age and condition
Do not use current asking prices alone. Evidence should relate to market value as of the applicable January 1 valuation date.
Final review action: Read the Assessor’s current Decline-in-Value guidance and confirm the filing period for the relevant assessment year.

How to File a Los Angeles County Assessment Appeal

A formal appeal is filed with the Assessment Appeals Board. The filing deadline depends on the type of assessment being challenged.

Assessment Type Filing Period Important Note
Regular annual assessment July 2 through November 30 For 2026, online regular-assessment filing opens July 2, 2026.
Supplemental assessment Within 60 days after the notice mailing date Do not wait for the regular annual filing period.
Adjusted assessment Within 60 days after mailing Use the date printed on the notice.
Escape assessment Within 60 days after mailing Escape assessments can involve earlier tax years.
Roll correction Within 60 days after mailing Read the corrected notice and appeal instructions carefully.
Misfortune or calamity reassessment Within six months after the proposed reassessment notice This appeal period is separate from the original Assessor damage claim.
Current filing fee: The Assessment Appeals Board charges a $46 nonrefundable application fee. An applicant experiencing financial hardship can review the official fee-waiver procedure.
1
Identify the assessment being challenged.

Confirm whether it is a regular, supplemental, escape, adjusted or calamity-related assessment.

2
Record the notice mailing date.

The mailing date controls many 60-day appeal periods. Keep the envelope and complete notice.

3
Verify the AIN and assessment year.

One owner can receive several notices for different parcels, years or supplemental events.

4
Identify the appeal issue.

Examples include value, base-year value, change in ownership, new construction, classification, decline in value or property characteristics.

5
Collect evidence for the correct valuation date.

Use comparable sales, appraisals, photographs, repair estimates, closing documents, construction records or income information.

6
Create an Applicant Login.

Use the official online portal or obtain the AAB-100 form for filing by mail or in person.

7
Pay the filing fee or submit a waiver request.

Follow the current instructions and keep proof of payment or waiver submission.

8
Save the complete application.

Keep the confirmation number, filed form, evidence list and every subsequent notice.

9
Prepare for the hearing.

State the requested value or correction clearly and organize the strongest evidence first.

10
Review the written decision.

The Board may decrease, increase or leave the assessment unchanged. Read further-review and payment requirements promptly.

Appealing does not automatically postpone tax payment. Confirm payment obligations with the Treasurer and Tax Collector while the appeal is pending.

Useful Assessment-Appeal Evidence by Property Type

Property or Issue Useful Evidence Common Mistake
Single-family home Comparable sales, condition photos, repair estimates and professional appraisal. Using homes from a different neighborhood, school area or condition class.
Condominium Same-building or similar-building sales, unit size, floor, view, parking and condition. Using the building address without matching the correct unit AIN.
Commercial property Rent roll, leases, vacancy, operating expenses, capitalization analysis and sales. Providing only gross income or asking rents.
Apartment property Unit mix, rents, expenses, vacancy, condition and comparable transactions. Ignoring rent restrictions or major deferred maintenance.
Vacant land Zoning, access, utilities, slope, environmental constraints and comparable land sales. Comparing developable land with constrained hillside or landlocked parcels.
New construction Permits, plans, invoices, completion date and description of replaced versus added improvements. Failing to separate repairs from assessable new construction.
Change in ownership Deed, trust, entity documents, probate records and exclusion claim. Arguing value when the real dispute concerns whether reassessment should have occurred.
Fire or disaster damage Dated photographs, insurance records, inspection reports, permits and repair estimates. Missing the separate Assessor and appeal deadlines.

Wildfire, Earthquake and Misfortune-or-Calamity Relief

Property substantially damaged by fire, earthquake, flood or another qualifying event may be eligible for temporary reassessment relief. The Assessor claim and any later Assessment Appeals Board appeal are separate steps.

1
Document the property immediately.

Take dated photographs and retain fire, building, insurance and emergency-response reports.

2
Search and save the AIN.

Confirm every damaged parcel, condominium unit or separately assessed structure.

3
Contact the Assessor promptly.

Request the current Misfortune or Calamity claim form and confirm the filing period for the event.

4
Provide damage and value information.

Include the date of damage, affected structures, estimated repair cost and supporting reports.

5
Review the proposed reassessment notice.

If the relief calculation is disputed, the formal Board appeal period is generally six months after the proposed reassessment notice.

Recorded-document help after a fire: The Registrar-Recorder/County Clerk provides special assistance for fire-impacted residents seeking copies of property records.
Do not confuse deadlines. The deadline for filing an Assessor damage claim is different from the later six-month period for appealing a proposed calamity reassessment.

Los Angeles County Property-Tax Bills and Due Dates

Annual secured property taxes are billed in two installments. Supplemental, unsecured, escape and corrected bills use their own dates and instructions.

Bill or Installment Normal Due Date Normal Delinquency Date
Annual secured first installment November 1 After December 10
Annual secured second installment February 1 After April 10
Supplemental bill Date printed on the supplemental bill Date printed on the bill
Unsecured bill Use the date printed on the unsecured bill Use the bill’s stated delinquency date
Escape or corrected tax bill Use the specific notice or bill Use the specific notice or bill
Weekend and holiday rule: When a statutory delinquency date falls on a weekend or legal holiday, the practical deadline may shift to the next business day. Verify the official calendar for the year.
No bill received does not cancel the tax. Search the AIN online and contact the Treasurer and Tax Collector when an expected bill is missing.

How to Search and Pay Los Angeles County Property Taxes

1
Find the correct AIN.

Use the property portal, Assessor record or current bill. Verify the property address and unit.

2
Identify the bill type.

Determine whether the bill is annual secured, supplemental, unsecured, escape, corrected or delinquent.

3
Open the official Treasurer and Tax Collector payment page.

Do not use a search advertisement or unofficial payment processor that is not linked by the county.

4
Enter the AIN and bill security information.

For certain secured-tax payments, use the six-character PIN printed on the bill. This is separate from the AIN.

5
Confirm the installment and payment status.

Check whether the first or second installment is unpaid, already paid, delinquent or submitted through mortgage escrow.

6
Review the full amount and any fee.

The official payment page displays available payment methods and any applicable processing charge before submission.

7
Submit the payment once.

Confirm the AIN, address, tax year, installment and total before authorizing payment.

8
Save the official confirmation.

Keep the receipt number, payment date, amount, AIN and installment.

9
Verify that the payment posts.

If the account remains unpaid after normal processing, contact the Treasurer before submitting another payment.

Mortgage-escrow warning: Owners should verify that the lender paid the correct AIN and installment rather than assuming escrow processing was completed.
Final payment action: Use the official Los Angeles County payment instructions or the county’s one-time payment system.

How to Obtain Los Angeles County Deeds, Liens and Recorded Documents

The Registrar-Recorder/County Clerk maintains Los Angeles County real-estate records dating back to 1850. Because of home-address privacy restrictions, the office does not provide unrestricted online access to its real-estate indexes or document images.

1
Collect the parcel information.

Save the AIN, property address, legal description and approximate transfer or recording date.

2
Identify the likely document.

Examples include grant deed, quitclaim deed, deed of trust, reconveyance, lien, release, easement, notice or court-related document.

3
Prepare grantor and grantee names.

The grantor generally transfers or grants an interest. The grantee generally receives the interest.

4
Submit an official records request.

Records can be requested online, by mail or in person through the Registrar-Recorder/County Clerk.

5
Compare the legal description and parties.

A matching address or name alone does not prove that the document belongs to the intended parcel.

6
Select informational or certified copies.

Legal, lender, court or title use may require certification rather than an ordinary copy.

Recorded-document telephone help: Call 800-201-8999 and use the real-estate-records option indicated by the current telephone menu.
Final records action: Review the official real-estate-record information and submit a record request.
Title warning: Ordering selected documents is not a complete title examination. Use a California title company or attorney for ownership, lien, probate, foreclosure or easement decisions.

Top 10 Los Angeles County Property Search FAQs

1. Is Los Angeles County CAD the official property office name?

No. Los Angeles County does not use a Texas-style county appraisal district. The official valuation office is the Los Angeles County Assessor.

2. How do I search Los Angeles County property records?

Use the official Los Angeles County Property Tax Portal or Assessor Portal. Search by property address or the 10-digit Assessor Identification Number, then verify the parcel address and AIN.

3. Can I search Los Angeles County property records by owner name?

The main public parcel search starts with an address or AIN rather than an unrestricted owner-name search. To research a deed by party name, request recorded-document information through the Registrar-Recorder/County Clerk.

4. What is the difference between an AIN and a payment PIN?

The AIN is the 10-digit number identifying the property parcel. The payment PIN is a separate six-character security code printed on certain secured tax bills and used for online payment access.

5. How much is the Los Angeles County Homeowners’ Exemption?

The Homeowners’ Exemption can reduce the assessed value of a qualifying principal residence by up to $7,000. It does not reduce the tax bill by $7,000. Current filing rules should be confirmed with the Assessor.

6. What is the Los Angeles County assessment-appeal deadline?

Regular assessment appeals are filed from July 2 through November 30. Supplemental, adjusted and escape assessments generally must be appealed within 60 days after mailing. Use the exact notice date and official instructions.

7. Is a Los Angeles County assessment appeal free?

No. The Assessment Appeals Board currently charges a $46 nonrefundable application fee. A hardship fee-waiver procedure is available for qualifying applicants.

8. How does Proposition 13 affect Los Angeles County property taxes?

Proposition 13 generally establishes a base-year value after a change in ownership or new construction and limits ordinary annual inflation adjustments to no more than 2%. The tax bill also includes the 1% general levy, voter-approved debt and direct assessments.

9. When are Los Angeles County secured property taxes due?

The first annual secured installment is due November 1 and normally becomes delinquent after December 10. The second is due February 1 and normally becomes delinquent after April 10, subject to weekend and holiday rules.

10. Where can I obtain a Los Angeles County deed or lien?

Request recorded real-estate documents from the Los Angeles County Registrar-Recorder/County Clerk online, by mail or in person. The county does not provide unrestricted online browsing of its real-estate-record indexes because of privacy restrictions.
