LA County Property Assessor 2026: Search & Tax Records

by
Los Angeles County Property Records Navigator

Find LA County Parcel Values, AIN Records and Property-Tax Bills

The official office is the Los Angeles County Office of the Assessor. It identifies taxable property, maintains parcel and building information, determines assessed values and administers exemptions. The Treasurer and Tax Collector issues and collects tax bills, while the Registrar-Recorder/County Clerk maintains deeds, liens and other recorded real-estate documents.

This guide shows how to search by Assessor Identification Number or property address, interpret Proposition 13 values, distinguish annual and supplemental bills, verify the 2026 assessment, use Proposition 19, pay a tax account, file an appeal and request a deed or lien copy.

LA County Property-Tax Status in August 2026

The 2026 regular assessment-appeal filing period is open. Los Angeles County accepts regular assessment appeals from July 2 through November 30. Owners questioning a 2026 value should review the Assessor record, collect January 1, 2026 market evidence and file before the deadline when informal contact does not resolve the issue.
2026 assessment concern The regular filing period remains open through November 30, 2026. The Assessment Appeals Board currently charges a $46 nonrefundable filing fee unless an approved hardship waiver applies.
Unpaid 2025–2026 taxes Secured taxes unpaid at the end of the fiscal year became tax-defaulted after July 1, 2026. Use the live Tax Collector record for the redemption amount.
Upcoming 2026–2027 bill Annual secured bills are normally mailed in October and no later than November 1. Confirm the mailing address before the billing cycle.
Do not wait for the October bill to dispute value: The appeal period is tied to the assessment roll and applicable notice, while the Treasurer and Tax Collector’s annual bill is mailed later.
Current-roll check: The Assessor Portal now displays the 2026 Current Roll on updated parcel records, together with 2027 Roll Preparation information when available.
Los Angeles County property-tax workflow

Four County Offices Control Different Parts of the Record

Office of the Assessor

  • AIN and parcel information
  • Land and improvement values
  • Proposition 13 base-year values
  • Exemptions and disaster reassessment
  • Ownership and mailing records
  • Property characteristics and maps

Auditor-Controller

  • Applies tax rates to assessed value
  • Adds voter-approved debt
  • Adds direct assessments
  • Processes Assessor roll changes
  • Calculates adjusted tax bills
  • Allocates collected property taxes

Treasurer and Tax Collector

  • Annual secured tax bills
  • Supplemental and adjusted bills
  • Payments and payment history
  • Duplicate bills and penalties
  • Defaulted-tax redemption
  • Installment plans and auctions

Registrar-Recorder

  • Deeds and deeds of trust
  • Liens and releases
  • Notices of default and sale
  • Recorded real-estate documents

  • Homeowner recording notifications
Important distinction: The Assessor determines assessed value but does not calculate or collect the final tax bill. The Treasurer and Tax Collector cannot change the Assessor’s valuation. The Recorder cannot determine whether a recorded document is legally valid or whether title is clear.
California and Nevada comparison: Los Angeles County and Clark County both separate assessment, tax collection and recorded-document services, but their valuation laws and payment calendars are very different. See the existing Clark County Assessor property search guide.

AIN and APN are synonymous

How to Read a Los Angeles County Assessor Identification Number

The Assessor Identification Number is a ten-digit parcel identifier. It is commonly written as four digits, three digits and three digits, such as 1234-567-890.

1234
–
567
–
890

AIN structure

  • First four digits: Assessor map book.
  • Middle three digits: Map page.
  • Final three digits: Parcel number.
  • AIN and APN: Both names refer to the same parcel identifier in LA County.
Use the AIN across systems: The same number connects the Assessor property profile, annual tax bill, supplemental bill, Tax Collector payment system, appeal application and many recorded-document requests.
New-development problem: A newly created home or condominium may not immediately have a searchable parcel record. Use the legal description, deed and title report when the address or new AIN has not yet populated.

Fields to Verify on an LA County Assessor Record

AIN Exact ten-digit parcel ID.
Situs address Physical property location.
Use type Residential, commercial or other.
Tax Rate Area Rate and jurisdiction area.
Parcel status Active, deleted or exempt.
Base year Proposition 13 value year.
Record field Meaning What to verify
Current Roll Assessed values enrolled for the active assessment year. Use this for a regular 2026 assessment appeal.
Roll Preparation Preliminary values being prepared for the next assessment roll. Do not confuse preparation data with a certified bill.
Land Value Assessed value assigned to the land component. Review base year, reason code and recent ownership events.
Improvement Value Assessed value assigned to buildings and taxable improvements. Check size, age, use, condition and new construction.
Base Value Value established after a qualifying change in ownership or new construction. Land and improvements may have different base years.
Reason Code Code indicating why or how a value was enrolled. Ask the responsible district office when the code is unclear.
Tax Status Shows whether the parcel is current, exempt or associated with defaulted taxes. Use the Tax Collector for the controlling balance.
Exemption Shows an exemption currently reflected on the parcel record. Confirm the exemption applies to the correct roll and bill.
Building Square Feet Assessor building-area record used in valuation and property description. Compare with permits, plans and actual configuration.
Legal Description Assessment description of the tract, lot or parcel. Use the recorded deed or survey for legal boundary questions.
Assessment-use warning: Assessor parcel maps and legal descriptions are useful for tax administration but do not replace a recorded deed, title report or licensed boundary survey.
California assessed-value system

How an LA County Assessed Value Becomes a Property-Tax Bill

Base Year Value Usually established when property changes ownership or taxable new construction is completed.
Land and improvement components can receive separate base years.
Factored Base Year Value Base value adjusted by the annual California inflation factor, limited to 2%.
This is the normal Proposition 13 value path.
Net Taxable Value Enrolled assessed value after qualifying exemptions are deducted.
Homeowners and disabled-veterans exemptions can reduce this value.
Total Tax Bill General 1% levy, voter-approved debt and direct assessments.
Direct assessments are not based on Assessor value.
Net taxable value Assessed value less qualifying exemptions
×
1% General property-tax levy
+
Other charges Voted debt and direct assessments
Why the bill is usually above exactly 1%: The 1% general levy is combined with voter-approved bonded indebtedness and direct assessments such as sewer, lighting, flood-control, refuse or other agency charges.
Ask the correct office: Question assessed value with the Assessor. Question a direct assessment with the agency telephone number printed next to that charge on the tax bill.
Proposition 13 and Proposition 8

Why Market Value and LA County Assessed Value Can Be Different

General levy

Proposition 13 generally limits the basic property-tax rate to 1% of net taxable value, plus voter-approved debt.

Annual inflation limit

The factored base year value can normally increase by the California inflation factor, but not more than 2% per year.

Temporary market reduction

Proposition 8 allows a temporary reduction when January 1 market value falls below the factored base year value.

A Proposition 8 value can rise by more than 2%: A temporarily reduced market-value assessment may increase with the recovering market, provided it does not exceed the property’s Proposition 13 factored base year value.
Longtime owner The assessed value may be far below current market value because annual factored increases were limited.
Recent buyer A qualifying purchase generally creates a new base year value near market value as of the ownership-change date.
New construction Newly completed taxable construction can create a new base value for the added improvement without revaluing unaffected property.
Review Official Proposition 8 Guidance Understand the difference between a temporary market reduction and the permanent Proposition 13 factored base value.
Base-year value transfer and family transfers

How Proposition 19 Can Affect an LA County Property Assessment

Original principal residence

The qualifying owner sells the original home and completes the replacement transaction within the required period.

Replacement principal residence

A qualifying base year value is transferred after both transactions are complete and the claimant occupies the replacement home.

Age 55 or older A qualifying owner can transfer the base year value to a replacement principal residence anywhere in California.
Severely and permanently disabled A qualifying owner can use the statewide replacement-home transfer rules.
Disaster victim A qualifying owner of a principal residence substantially damaged by an eligible wildfire or natural disaster may transfer the base value.
Key replacement-home rules: The replacement must generally be purchased or newly constructed within two years of the sale of the original principal residence. Eligible claimants can generally use the Proposition 19 transfer up to three times.
Higher-value replacement: A replacement home may cost more than the original home, but the amount above the applicable equal-or-lesser-value test is added to the transferred taxable value.

Parent-child and grandparent-grandchild transfers

Family home requirement For the family-home exclusion, the property generally must be the transferor’s principal residence and become the eligible transferee’s principal residence.
Filing sequence The transferee generally must claim the homeowners exemption within one year and file the Proposition 19 exclusion claim within the applicable three-year period or before transferring the property again.
Not automatic through escrow: A Proposition 19 base-year transfer requires a claim with the Assessor after the qualifying transactions and occupancy requirements are satisfied.
Open Official Proposition 19 Guidance Review replacement-home transfers, family-home exclusions, forms, timing and statewide rules.

LA County Homeowners and Disabled-Veterans Exemptions

$7K
Homeowners Exemption

Reduces the assessed value of a qualifying principal residence by up to $7,000, producing approximately $70 in annual general-levy savings.

HOX
Supplemental application

The homeowners exemption can also reduce a qualifying supplemental assessment when the prior owner did not claim it.

DV
Basic Disabled-Veterans Exemption

Provides an inflation-adjusted exemption for a qualifying principal residence. The basic exemption normally requires an initial claim rather than annual refiling.

LI
Low-Income Disabled-Veterans Exemption

Provides a larger inflation-adjusted exemption, subject to an annually adjusted household-income limit and annual filing.

Homeowners exemption readiness

  • Own the dwelling
  • Occupy it as the principal residence
  • Qualify as of January 1 for the annual roll
  • Use the correct AIN
  • Provide owner information
  • Submit the BOE-266 claim
  • Notify the Assessor after moving
  • Recheck the exemption on the Assessor record
New property owners: The Assessor generally mails a homeowners exemption claim form after a qualifying ownership change. Owners should still verify filing rather than assuming escrow completed the exemption.
One residence exemption: A homeowners exemption and disabled-veterans exemption are not both applied to the same residence. A qualifying disabled veteran normally claims the more advantageous disabled-veterans exemption.
Read LA County Exemption Guidance Review principal-residence, homeowners and ownership questions. Review Disabled-Veterans Rules Confirm qualification, filing timing, documentation and annual low-income requirements.
Misfortune and calamity reassessment

Temporary Property-Tax Relief After Fire, Flood or Other Damage

Minimum damage The property must generally sustain at least $10,000 in qualifying physical damage.
Claim deadline File Form ADS-820 within 12 months of the date of the damage.
Possible result The Assessor can reassess the damaged property as of the damage date, resulting in an adjusted bill or refund.
Document damage Take photographs and preserve insurance, fire, permit and repair records.
File ADS-820 Submit the misfortune-and-calamity claim within the required 12 months.
Assessor review The Assessor determines the value loss as of the damage date.
Adjusted billing Taxes can be prorated until repair, replacement or another reassessment event.
Keep paying unless instructed otherwise: Filing a disaster claim does not automatically cancel an existing payment deadline. Review the bill and request official guidance about any affected installment.
Appeal period after proposed disaster reassessment: Los Angeles County provides a separate six-month appeal period after mailing the Assessor’s proposed misfortune-and-calamity reassessment notice.
Do not assume one property means one bill

Annual, Supplemental, Adjusted and Unsecured Tax Bills

Bill type Why it is issued Payment rule
Annual Secured Regular fiscal-year property tax secured by real property. First installment due November 1; second due February 1.
Supplemental Secured Reassessment after a qualifying ownership change or completed new construction. Use the unique due and delinquency dates printed on that bill.
Adjusted Secured Replaces or changes an earlier bill after value, exemption, direct-assessment or rate correction. Follow the replacement bill and confirm whether prior payments were credited.
Escape Assessment Prior-year taxable value that was not previously enrolled. A qualifying amount over $500 may be eligible for a four-year plan if opened before delinquency.
Unsecured Personal property or an assessment not secured by real property. Annual unsecured bills are generally due by August 31 unless the bill shows another date.
Supplemental bills are separate: Paying the annual secured bill does not pay a supplemental bill. A purchase or new construction between January 1 and May 31 can generate two supplemental assessments.
Escrow warning: Supplemental bills are generally mailed directly to the owner and are often not paid from the mortgage impound account. Confirm with the lender rather than assuming payment.
Open the Supplemental Bill Decoder Review the AIN, year and sequence, transfer or construction date, prior value, current value, proration factor and unique due dates.

New owner, missing bill and escrow

What to Do When the Bill or Owner Information Looks Wrong

No annual bill by November 1 Request a duplicate bill and search the live tax account. Failure to receive the bill does not cancel the payment obligation or penalties.
Prior owner remains on bill Annual bills are mailed to the owner listed on the secured roll. A first-year bill can still show the prior owner while the deed and Assessor records are being processed.
Mortgage company pays taxes An “Information Only” statement often means the lender receives the payment bill. Compare the lender’s escrow disbursement with the Tax Collector account.
Supplemental bill received Send a copy to the lender, but do not assume the impound account will pay it. Supplemental bills are generally the owner’s direct responsibility.
New parcel not searchable Use the deed, title report and legal description. Contact the Assessor to learn when the parcel and first annual assessment will be created.
Mailing address is outdated Submit the change to the Assessor. Updating a postal forwarding order does not automatically update the county assessment roll.
New-owner budget: Prepare for the annual secured bill plus one or two supplemental bills. The supplemental obligation can arrive several months after the purchase and may not be included in the monthly mortgage payment.

LA County Tax-Defaulted Property and Installment Plans

Late installment The county applies the 10% installment penalty and the second-installment cost when applicable.
Tax default Unpaid secured taxes become defaulted after the fiscal year closes on June 30.
Redemption charges A monthly redemption penalty and redemption fee are added to the outstanding amount.
Sale eligibility Property can eventually become subject to a tax-defaulted property sale if the default is not redeemed.
2025–2026 default position: Unpaid secured taxes became tax-defaulted after July 1, 2026. County examples show a redemption penalty of 1.5% of base tax per month and a $15 redemption fee. Use the live account for the exact amount.
Four-Pay Plan A qualifying prior-year escape assessment over $500 can be paid through a four-year plan when the plan is opened before that escape bill becomes delinquent.
Five-Pay Redemption Plan Qualifying defaulted residential or agricultural property and certain vacant or nonresidential property can enter a five-year redemption plan within the applicable default period.
Current taxes still matter: A Five-Pay Plan requires annual payment of the plan amount, interest and current-year property taxes. Missing a required payment can default the plan.

How to Request LA County Deeds, Liens and Real-Estate Records

No public internet index: Los Angeles County does not provide online public access to its real-estate document index or document images. Records can be reviewed by appointment or requested online, by mail, fax or in person.
Identify the document. Determine whether you need a grant deed, quitclaim deed, deed of trust, lien, release, notice of default, notice of sale or another instrument.
Gather the recorded names. Prepare the names of the parties exactly as they likely appeared when the document recorded.
Find the recording year. County indexes are maintained by name and year. A broad multi-year search can create additional search fees.
Use the Assessor history when available. The Assessor Portal can display a recording date and document number associated with an ownership event.
Choose a request route. Request through the official online vendor, schedule an in-person appointment or send a mail request.
Order the correct copy type. A plain copy is suitable for many research purposes. A court, lender or government process may require certification.
Review every page. Match the parties, legal description, recording date, instrument number and return address.
Search releases separately. A recorded lien, deed of trust or notice does not prove whether a later release, satisfaction or reconveyance was recorded.

LA County Property Assessor Search and Tax Records FAQs

1. How do I search LA County Assessor property records?

Use the official Los Angeles County Assessor Portal and search by the complete 10-digit Assessor Identification Number or property address. Open the result and verify the AIN, situs address, use type, parcel status, Tax Rate Area, current roll values and legal description.

2. What is an LA County AIN or APN?

The AIN is the Assessor Identification Number assigned to a real-property parcel. It contains ten digits in a four-three-three format, such as 1234-567-890. AIN and APN are synonymous in Los Angeles County.

3. What does the LA County Assessor handle?

The Assessor maintains parcel and building data, determines assessed values, administers exemptions, processes qualifying ownership and construction reassessments and handles disaster reassessment claims. The Treasurer and Tax Collector separately issues and collects tax bills.

4. How does Proposition 13 affect an LA County property value?

Proposition 13 generally establishes a base year value after a qualifying ownership change or new construction and limits annual inflationary increases in that base value to no more than 2%. The general property-tax levy is 1% of net taxable value, plus voter-approved debt and direct assessments.

5. When are 2026–2027 LA County property taxes due?

The first annual secured installment is due November 1, 2026 and becomes delinquent after December 10, 2026. The second installment is due February 1, 2027. The statutory April 10 delinquency date falls on Saturday in 2027, so the next-business-day rule applies.

6. What are the LA County online property-tax payment fees?

The official county eCheck payment route has no service fee. Credit and debit card payments currently carry a 2.22% processor fee with a $1.49 minimum. Review the authorization screen before submitting because processor terms can change.

7. What is an LA County supplemental property-tax bill?

A supplemental bill reflects the difference between a prior assessed value and a new value after a qualifying ownership change or completed new construction. It is separate from the annual bill, has unique due dates and is generally not paid through the mortgage impound account.

8. How much is the LA County Homeowners Exemption?

The Homeowners Exemption reduces the assessed value of a qualifying principal residence by up to $7,000, which produces approximately $70 in annual general-levy savings. The owner must occupy the home as the principal residence and file the required claim.

9. How do I appeal a 2026 LA County property assessment?

Review the Assessor record, contact the responsible district office and file an Assessment Appeal Application between July 2 and November 30, 2026 if the issue remains unresolved. The regular application currently requires a $46 filing fee unless an approved hardship waiver applies.

10. Where do I search LA County deeds and liens?

The Registrar-Recorder/County Clerk maintains deeds, liens and other real-estate records, but its index and document images are not publicly searchable online. Request a record online, by mail or fax, or schedule an appointment at the Norwalk office using the document title, party names and recording year.

Find the Correct County Office

Property Appraiser, Tax Collector, Clerk, GIS, and VAB offices do different jobs. Pick your task below.

Quick rule: Property Appraiser = value, records, parcel details, exemptions. Tax Collector = bill and payment. Clerk/Recorder = deeds and recorded documents. VAB = formal value disputes.

Official Property Search Helper

Use this when a county article tells you to search by owner, address, parcel number, folio, PCN, STRAP, or alternate key.

Search tip: If address search fails, try only the house number and main street name. Avoid typing Street, Avenue, Road, Drive, unit numbers, or punctuation unless the official portal requires it.

Homestead Exemption Readiness Check

This helps homeowners prepare before filing through the official county Property Appraiser website.

Important: This is not an eligibility decision. The official county Property Appraiser decides approval, required documents, late filing options, and exemption status.

TRIM Notice & Value Review Helper

Use this to organize your questions before calling the Property Appraiser or preparing an appeal.

Your preparation checklist

Value term Simple meaning
Market value The appraiser’s estimate of the property’s value as of the assessment date.
Assessed value The value after limits or caps may be applied.
Exemptions Approved reductions such as homestead or other exemptions.
Taxable value The value used by taxing authorities after exemptions.

Property Tax Bill Direction Helper

The Property Appraiser values property, but the Tax Collector usually handles the actual bill and payment.

Florida timing reminder: Many Florida tax bills are mailed around November and become delinquent if unpaid after March 31. Always verify exact dates, discounts, and payment fees with the official county Tax Collector.
