California Property Tax Records: County Assessor Search, Tax Bills, Deeds, Prop 13, Exemptions & Appeals Guide
California property tax records are county-based. There is no single statewide portal that shows every owner, parcel, deed, tax bill and map in one place. Start with the county assessor for parcel and assessed value, the county treasurer-tax collector for bills and payments, the county recorder or clerk-recorder for deeds, and the clerk of the board for assessment appeals.
This statewide guide explains how to search California property records correctly, how Prop 13 affects assessed value, when secured tax bills are due, where deed records live, how exemptions work, and what to do when you need an appeal, supplemental bill, transfer, or official copy.
Fastest Way to Search California Property Tax Records
Which California County Office Handles Each Property Record?
California’s 58 counties use different portals and names. The office function is the same even when the title changes.
| Your Question | Use This Office | What It Usually Shows | Search Details to Prepare |
|---|---|---|---|
| Who owns it, what is the APN, and what is the assessed value? | County Assessor | APN, situs/property address, owner mailing name, assessed land/improvement value, exemptions, transfer history, property characteristics and maps. | APN, address, owner name, tract/map number, legal description or city. |
| How much property tax is due? | Treasurer-Tax Collector | Current secured tax bills, installment amounts, delinquency, penalties, online payments, refunds, tax-defaulted property and tax sale information. | APN, bill number, address, tax year or owner mailing name. |
| Where is the deed, lien or mortgage? | Recorder / Clerk-Recorder / Registrar-Recorder | Grant deeds, deeds of trust, reconveyances, liens, maps, notices, official copies and recording index. | Grantor/grantee name, recording date, document number, book/page, APN or map reference. |
| Where is the parcel on a map? | County Assessor GIS / County GIS | Parcel boundary map, APN map book/page, land use, zoning layers, flood/fire layers where available. | APN or simplified property address. |
| How do I challenge the value? | Clerk of the Board / Assessment Appeals Board | Appeal forms, filing period, hearing rules, board contact, evidence requirements and status. | Assessment notice, APN, owner, value opinion, comparable sales and filing deadline. |
How to Search California Property Records by APN, Address or Owner
The cleanest statewide search pattern is: county first, assessor second, APN third, then tax collector and recorder.
Best key
Use the Assessor Parcel Number when available. It avoids owner-name spelling, trust and LLC search problems.
Use simple format
Search house number and street name first. Remove unit, punctuation, direction and suffix when the county portal fails.
Least reliable
Owner searches can miss results because of trusts, LLCs, estates, spouse names and mailing-name formats.
1
Confirm the county firstDo not rely on city name alone.
▾
California cities can cross county lines, and ZIP codes can cover more than one county. Confirm the county using the property address, assessor map, deed, tax bill, escrow papers or county GIS.
2
Open the county assessor property searchSearch APN first, then address, then owner.
▾
Search the assessor portal for APN, situs address, assessed value, exemption, transfer and property-characteristic details. If the county does not provide owner names online, use the APN to continue with tax and recorder records.
3
Use the APN in the tax collector portalBill records are separate from assessment records.
▾
Search the county treasurer-tax collector by APN, bill number or address. Confirm installment amounts, penalties, tax year, payment status and whether the bill is current, supplemental, escaped, unsecured or tax-defaulted.
4
Search the recorder for legal documentsUse grantor/grantee names and dates.
▾
Use the owner/seller/buyer names from the assessor record, deed or closing statement to search deeds, deeds of trust, reconveyances, liens and maps. Search forward after each mortgage or lien for releases or reconveyances.
California Prop 13, Assessed Value and Supplemental Assessments
California property tax records can look confusing because market value, assessed value, taxable value and tax bill amount are not the same thing.
| Term | What It Means | Where to Verify |
|---|---|---|
| Market value | Estimated fair market value. Used for reassessment events, decline-in-value reviews and appeals. | County assessor, sales evidence, appraisal, comparable sales. |
| Base year value | Prop 13 value established by purchase/change in ownership or new construction, then adjusted annually within limits. | County assessor value history. |
| Assessed value | Value placed on the roll for property tax purposes after Prop 13 rules and reassessment events. | County assessor record or assessment notice. |
| Taxable value | Assessed value after eligible exemptions, exclusions or reductions. | Assessor record and tax bill. |
| Supplemental assessment | Additional assessment after a change in ownership or completed new construction; can create a supplemental tax bill separate from the annual bill. | Assessor supplemental notice and tax collector supplemental bill. |
California Secured Property Tax Bill Dates
Most California real property is on the secured roll. Counties mail secured tax bills by November 1, and the bill is usually split into two installments.
Due Nov 1
The first installment of secured property taxes is due and payable on November 1.
After Dec 10
If unpaid after December 10, the first installment becomes delinquent and penalty applies.
Due Feb 1
The second installment is due and payable on February 1.
After Apr 10
If unpaid after April 10, the second installment becomes delinquent and penalty/costs apply.
1
Search the tax bill before payingCounty tax collector records control payment status.
▾
Use the county treasurer-tax collector portal. Search by APN, bill number, address or tax year. Confirm installment, amount, delinquency, penalty, convenience fees and payment deadline before submitting money.
2
Do not wait for a paper billNot receiving a bill is not usually a safe defense.
▾
If you bought, inherited, refinanced or changed mailing address, search the tax collector portal early. Counties may send bills to the mailing address on file, and escrow timing can cause confusion.
3
Watch supplemental and escaped billsThese are separate from the regular secured bill.
▾
A purchase, transfer, completed new construction, or correction can generate a supplemental or escaped assessment bill. These bills can arrive outside the normal November/February installment pattern.
Where to Find California Deeds, Trust Deeds, Liens and Recorded Maps
Legal property documents are recorded at the county recorder, clerk-recorder, registrar-recorder or assessor-recorder depending on the county.
Ownership transfer
Grant deed, quitclaim deed, interspousal deed, trustee’s deed and other conveyance documents are recorder records.
Trust deed / lien search
Deeds of trust, reconveyances, liens, notices of default and releases are searched through official recorded documents.
Tract and parcel maps
Recorded tract maps, parcel maps and subdivision maps are usually recorded-document or recorder map records.
1
Use grantor/grantee namesRecorder searches usually work by names and recording dates.
▾
Use the seller, buyer, lender, trustee, trust, LLC or lienholder name. Search both grantor and grantee. If you only have an APN, use the assessor first to identify party names.
2
Search forward after every loan or lien documentYou need the release too.
▾
After finding a deed of trust, mortgage-style document, lien, notice or assignment, search later dates for reconveyance, release, satisfaction, substitution, rescission, assignment or correction records.
3
Order official copies from the county recorderAvoid third-party deed-copy mailers.
▾
Official copies and certified copies should be ordered from the county recorder/clerk-recorder. Fees, online image access and copy rules vary by county.
California Homeowners’ Exemption, Disabled Veterans’ Exemption and Prop 19
Exemption and transfer rules are filed with the county assessor where the property is located. Do not file these with the recorder or tax collector unless the county specifically instructs you to.
| Program | What It Can Do | Where to Start |
|---|---|---|
| Homeowners’ Exemption | Deducts up to $7,000 from assessed value for a qualifying principal residence. | County assessor; BOE-266 claim form. Official info: BOE Homeowners’ Exemption. |

| Parent-child / grandparent-grandchild transfer rules | Certain family transfers may qualify for exclusion rules, but post-Prop 19 limits are stricter than older rules. | County assessor and BOE Prop 19 forms/guidance. |
| Decline-in-value / Prop 8 review | Temporary reduction when market value falls below factored base-year value. | County assessor review first, then assessment appeals if needed. Official info: BOE Decline in Value. |
How California Property Assessment Appeals Work
An assessment appeal challenges the assessed value or assessment issue. It does not directly challenge the tax rate, voter-approved debt, special assessments or the fact that a bill is due.
July 2-Sept 15
In many counties, the regular secured roll appeal period runs July 2 through September 15.
Until Nov 30
If the assessor does not provide required value notices by August 1, the regular filing period can extend to November 30.
Usually 60 days
Supplemental assessment appeals commonly have a 60-day filing window from notice mailing.
1
Talk to the county assessor firstInformal review can fix data errors.
▾
Ask the assessor how the value was determined. Check square footage, land use, condition, comparable sales, exemptions, new construction, ownership change and supplemental events.
2
File with the county clerk of the boardUse county forms and county deadlines.
▾
Appeal applications are filed with the county clerk of the board or assessment appeals board. Official BOE overview: California assessment appeals.

Bring evidence, not frustrationValue proof wins appeals.
▾
Use comparable sales, appraisal support, photos, contractor estimates, rent/income evidence for income property, incorrect property data, purchase documents or market evidence tied to the relevant lien date or supplemental date.

If Your California Property Record Search Fails
| Problem | Likely Cause | Best Fix |
|---|---|---|
| No address result | Street suffix, unit, punctuation, unincorporated address, city/county mismatch or portal formatting. | Search only house number and street name; confirm county; try APN from a tax bill or deed. |
| No owner result | Trust, LLC, estate, privacy limits, mailing-name format or county does not publish owner search online. | Use APN/address first; search recorder grantor/grantee names; contact assessor if public online search is limited. |
| Tax bill looks different from sale price | Prop 13 base-year value, exemptions, supplemental bills, special assessments or voter-approved debt. | Compare assessed value, taxable value, tax rate area, exemptions and supplemental bills separately. |
| Deed search is confusing | Recorder search uses grantor/grantee and recording date, not always APN or property address. | Use assessor record to identify names; search date ranges around sale/refinance; order official copies from recorder. |
| Need title proof | Assessment and tax records are not complete title reports. | Search recorder records and consult a title company or attorney for title, lien, easement or ownership reliance. |
California Property Tax Record Tips That Save Time
Use these whether you are searching in Los Angeles, San Diego, Orange, Riverside, San Bernardino, Alameda, Sacramento, Santa Clara, Contra Costa, Fresno, Ventura, San Mateo, Kern, San Francisco, Placer or any California county.
APN first, names second
APN is the strongest key across assessor, tax collector, GIS and sometimes recorder workflows.
Check county, not just city
City names and mailing cities can mislead you. Property records are county-administered.
Expect supplemental bills after buying
Buying or building can create a separate supplemental bill in addition to the regular secured bill.
Do not ignore Dec 10 and Apr 10
These are the big secured tax delinquency dates for many California property owners.
Recorder records prove documents
Assessor records are for assessment; recorder records show recorded deeds, liens and maps.
File claims with the assessor
Homeowners’ exemption, disabled veterans’ exemption and Prop 19 claims are county assessor tasks.
California Property Tax Records FAQs

QWhen are California secured property taxes due?▾
The first installment is due November 1 and becomes delinquent after December 10. The second installment is due February 1 and becomes delinquent after April 10. Always verify exact rules with the county tax collector.
QWhere do I find California deeds and liens?▾
