La County CAD Property Search Appraisal District

Use the Los Angeles County Assessor Portal rather than a commercial people-search, deed-selling or tax-estimate website.

Start with the street number and main street name. Add the city or ZIP code when the system shows several possible locations.

Try the address without apartment wording, punctuation, street-direction abbreviations or the full street-type suffix.

Verify the street address, city, ZIP code, parcel description and AIN. Condominiums, parking spaces and adjoining lots may use separate numbers.

Review the land value, improvement value, total assessed value, use code, year built, building area and map information.

The AIN is the most important identifier for checking bills, payment history, maps, exemptions and appeals.

Keep a dated copy with the deed, tax bill, closing papers, exemption forms and any assessment notice.

Do not begin boundary research from a street address alone when the property contains several parcels.

Search or navigate to the parcel using the verified AIN.

Check whether the property includes a separate parking parcel, vacant lot, access strip or adjoining tract.

Review street frontage, parcel shape and nearby parcel numbers.

Recorded maps, deeds, easements and a licensed surveyor control when legal boundaries matter.

Verify the property address and parcel before opening the tax system.

Use the Treasurer and Tax Collector’s property-tax service rather than a third-party payment advertisement.

Annual, supplemental, adjusted and prior-year bills may appear separately.

A recently purchased or improved property may have both an annual bill and one or more supplemental bills.

Confirm whether each installment is unpaid, paid, delinquent or handled through mortgage escrow.

Keep the bill with the closing statement, escrow records and payment confirmations.

Verify that the page belongs to the Los Angeles County Treasurer and Tax Collector.

Use the correct AIN and any bill-specific information displayed on the tax statement.

Confirm the tax year, bill type, property address and payment status.

Use eCheck to avoid the standard card service fee when the bank account is ACH-enabled.

Check the base tax, penalties, interest and processing fee before authorizing payment.

Do not repeat the transaction merely because the account does not update immediately.

Keep the confirmation number, AIN, amount, date, tax year and installment.

Contact the Treasurer before making a second payment when the first payment is not visible after normal processing.

Do not use the regular appeal window for a supplemental or escape assessment with a separate 60-day deadline.

The mailing date can determine whether the appeal is timely.

One property owner can receive several notices for different parcels or events.

Possible issues include market value, decline in value, new construction, change in ownership or incorrect property data.

Use comparable sales, appraisal reports, photographs, repair estimates, deeds, permits or income records.

Pay the filing fee or include a properly completed hardship-waiver request.

Keep the application, attachments, receipt and every hearing notice.

Prepare the AIN, street address, legal description and approximate recording date.

Examples include grant deed, quitclaim deed, deed of trust, reconveyance, lien, release, easement or notice.

Use the grantor and grantee names shown in the transaction or title documents.

The Recorder provides online request, in-person, fax and mail options.

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

A certified copy may be required for court, lender, title, probate or other official use.
