San Francisco County Property Assessor Search & Lookup 2026

by
City & County of San Francisco • 2026 Property Lookup Guide

Search San Francisco Block/Lot Records, Assessed Values, Tax Bills & Deeds

San Francisco does not have separate city and county property-assessment offices. It is a consolidated city-county, and the official valuation and recording agency is the Office of the Assessor-Recorder. That office establishes taxable property values, handles exemptions and ownership-related reassessment, and also records deeds and other real-estate documents.

The local key to almost every property search is the Assessor Block and Lot number. A parcel may appear in a format such as 0787/001. Once you have that Block/Lot, you can connect the Planning Property Information Map, assessment information, the Treasurer & Tax Collector’s secured-tax bill, recorded deeds, permits, zoning, complaints and parcel-map research without relying only on an owner name or street address.

For August 2026, there is one especially important deadline: the regular formal assessment appeal window is open now through September 15, 2026. Owners who disagree with the 2026 regular-roll value should not wait for the October property-tax bill.

The San Francisco 2026 Assessment Appeal Window Is Open Now

Regular-roll assessment appeals can be filed July 2 through September 15. As of August 12, 2026, the window is open. The Assessment Appeals Board currently charges a nonrefundable $60 filing fee.
Think the 2026 value is too high? File the formal appeal before September 15 rather than waiting for the October secured tax bill.
Single-family informal review? The normal January 2–March 31 informal decline-in-value review period has already passed for 2026.
Waiting for the next secured bill? San Francisco normally mails secured real-property tax bills in October.
Online deadline risk: Assessment Appeals Board terms require the application and fee to be successfully received by the filing deadline. A failed online transaction completed only after the deadline can leave the appeal untimely.
Do not use the FY 2025–26 tax rate as the upcoming FY 2026–27 rate. The Treasurer’s currently published secured rate is 1.18268325% for FY 2025–26. This guide did not verify a finalized FY 2026–27 rate as of August 12, 2026; use the rate printed on the upcoming 2026–27 bill once issued.
City-county structure

Why “San Francisco County Assessor” Means the Assessor-Recorder

San Francisco is both a city and a county. Instead of a separate municipal assessor and county recorder, one elected Assessor-Recorder agency performs both assessment and recording functions.

Assessment side Locates taxable property, identifies ownership, establishes taxable value and applies exemptions.
Recorder side Records deeds, deeds of trust, reconveyances, liens, maps and many other official documents.
Separate tax collector The Treasurer & Tax Collector issues and collects the property-tax bill after the assessment roll and annual tax rate are established.
Three offices, three different problems

Jump to Your San Francisco Property Question

San Francisco’s parcel key

What Does a San Francisco Block/Lot Number Mean?

Block The Assessor block identifies the larger mapped block or assessment area.
Lot The lot identifies the individual assessment parcel within that block.
Example 0787/001 means Block 0787, Lot 001.
Why save it? San Francisco’s tax bill, Planning property map and several Assessor/Recorder workflows all use the Block/Lot as a primary parcel identifier.
Condominiums can be tricky. Multiple condo lots can share the same street address. Always verify the exact lot rather than assuming the building address alone identifies your unit.
More than an assessor lookup

What You Can Pull From the SF Property Information Map

Assessor Summary Parcel-oriented assessment summary information.
Zoning Information Zoning and planning designations affecting use and development.
Building Permits Building-permit activity tied to the property.
Planning Applications Planning cases, applications and entitlement history.
Historic Preservation Historic resources and preservation-related information.
Environmental Information Environmental layers and mapped conditions.
Complaints & Appeals Certain complaint and appeal records associated with the property.
Assessor Block Map Map context useful for identifying the parcel within its assessment block.
Map data is a research aid—not a boundary survey. For an encroachment, lot-line, easement or ownership dispute, review recorded maps/deeds and obtain professional survey/title help.

Verify These Six Fields Before Appealing or Paying

Block Match exact block.
Lot Match exact lot/unit.

San Francisco Property Assessment & Tax Record Decoder

Field / concept What it means What to do with it
Block / Lot San Francisco parcel identifier. Use across PIM, tax bill and Recorder research.
Base-Year Value Prop 13 starting value, generally tied to 1975 or the most recent qualifying change in ownership/new construction. Do not compare a longtime owner’s taxable value directly with current sale price without understanding Prop 13.
Factored Base-Year Value Base-year value after annual Prop 13 inflation adjustments, generally capped at 2% per year. Compare with current market value when evaluating Prop 8 decline.
Market Value Current fair market value as of the applicable lien/valuation date. A lower January 1 market value can support temporary Prop 8 treatment.
Gross Taxable Value Assessed taxable value before exemptions. Compare with exemption and net taxable value.
Exemptions Qualifying value removed, such as Homeowners’ Exemption. Verify whether the exemption is actually reflected.
Net Taxable Value Gross taxable value minus exemptions. This is the value used with the annual tax rate.
Direct Charges Separate charges or assessments not produced simply by multiplying taxable value by the ad valorem rate. Review separately if total bill seems higher than your rate calculation.
Tax Bill Number Unique bill identifier. Helpful for payment/account servicing.
California taxable-value foundation

How Proposition 13 Controls San Francisco Assessed Value

Under Proposition 13, a property’s base-year value is generally established at its 1975 value or when a later qualifying change in ownership or new construction occurs.

That base value can normally increase each year by the lower of the California inflation factor or 2%. This creates the property’s factored base-year value.

If the property’s January 1 market value drops below that factored base-year value, California’s decline-in-value rules can temporarily reduce the enrolled value.

Why neighboring homes can have dramatically different assessments: two identical properties can have very different Prop 13 base years because their ownership histories are different.
Sale price does not automatically become the exact assessment in every situation. Change-in-ownership exclusions, partial interests, Prop 19 and other statutory rules can alter the outcome.
Temporary decline in value

Prop 8 Decline-in-Value Review

A Prop 8 reduction is different from permanently resetting the Proposition 13 base year. It is a temporary enrollment when current market value falls below the factored base-year value.

Informal review San Francisco’s single-family residential review period normally runs January 2 through March 31.
Formal appeal All property owners can use the formal Assessment Appeals Board process during the regular July 2–September 15 filing period.
Value can rebound faster than 2% A temporary Prop 8 value can rise by more than 2% in a later year while it remains below the property’s Prop 13 factored base-year ceiling.
A Prop 8 reduction does not establish a new lower permanent Prop 13 base year. When market value recovers, the temporary value can increase until it reaches the factored base-year amount.

Current date Appeal period is open now.
Filing fee Current nonrefundable fee.
Build support Comparable sales, appraisal and property-condition facts.
Deadline Application and fee must be successfully received.
AAB review Prepare to support your requested value.
Find your exact Block/Lot. Use PIM or the tax bill so you appeal the correct assessment unit.
Review the value you are challenging. Distinguish regular-roll value from a supplemental or escape assessment.
Open the Assessment Appeals Board. Go to San Francisco Assessment Appeals Board.
Create/sign in to the online account if filing electronically. Follow the application prompts and select the correct parcel and assessment type.
State your opinion of value. Do not submit only “my taxes are too high.” Value evidence must address the assessment.
Pay the $60 filing fee. Treat the filing as incomplete until the payment is successfully processed.
Save submission confirmation. Keep screenshots/PDF confirmations showing successful filing and payment before the deadline.
Prepare the evidence again for the hearing. Organize comparable sales, appraisal documents, photos and factual corrections in a clear parcel-specific file.

Appeal evidence checklist

  • Block/Lot number
  • 2026 assessment value
  • Your requested market value
  • Comparable sales near January 1
  • Independent appraisal if useful
  • Condition photographs
  • Repair/defect documentation
  • Wrong square-footage evidence
  • Purchase/ownership documents
  • Prop 13 / Prop 8 history
Appealing does not stop the tax-payment deadline. Pay the property tax on time even while a value appeal is pending unless an official agency gives you different written instructions.
“I am appealing San Francisco Block/Lot __________. The 2026 enrolled value is __________ and my opinion of January 1 market value is __________ based on __________. Please confirm the appeal type, filing status, fee receipt and any evidence deadline.”
Sale, transfer or new construction

Supplemental Assessments Can Create a Separate Tax Bill

When a change in ownership or new construction establishes a higher taxable value, San Francisco can issue a supplemental assessment in addition to the normal annual secured roll.

Old value The parcel had an existing taxable base before the qualifying event.
New value Assessor-Recorder establishes the new taxable value attributable to the ownership change or construction.
Supplemental difference The tax generally reflects the difference and can be prorated based on when the event occurred.
Do not assume the regular October secured bill includes every supplemental obligation. A recent buyer or owner completing new construction should search for any separate supplemental bill.
Supplemental and escape assessments can have different appeal deadlines from the normal September 15 regular-roll deadline. Read the notice and use the Assessment Appeals Board instructions for the exact assessment type.
Principal residence exemption

California Homeowners’ Exemption in San Francisco

A qualifying owner who occupies the property as a principal residence on January 1 can receive the California Homeowners’ Exemption, which reduces taxable assessed value by up to $7,000.

Taxable-value reduction Up to $7,000 is removed from taxable assessed value for a qualifying principal residence.
Principal residence The property generally must be the owner’s principal residence as of January 1.
Full exemption filing February 15 is the normal full-exemption filing deadline for a first-time claim.
Usually one-time filing Once approved, the exemption generally continues until ownership or principal-residence eligibility changes.
February 15, 2026 has passed. If you recently purchased or occupied a home, file promptly with the Assessor-Recorder rather than assuming there is no remaining partial/supplemental benefit.
Base-year transfer and family-transfer rules

Prop 19 Can Change the Result After a Sale or Family Transfer

Age 55+ / disabled / disaster victims Qualifying owners may transfer an existing base-year value to a replacement principal residence elsewhere in California, subject to Prop 19 rules.
Up to three transfers Eligible age-55 or severely disabled claimants can generally use the replacement-residence benefit up to three times.
Parent-child rules are narrower Family transfer exclusion is generally tied to qualifying principal-residence/family-home treatment rather than the broader pre-Prop-19 exclusion system.
Do not assume “family transfer = no reassessment.” Prop 19 requires specific use, occupancy, value and filing conditions.
Check San Francisco Prop 19 Review current claim forms and requirements before relying on the prior owner’s taxable value.
Treasurer & Tax Collector

How San Francisco Assessed Value Becomes the Secured Property Tax Bill

1. Gross Taxable Value Assessor-Recorder enrolls taxable land/improvements and applicable assessed value.
2. Exemptions Homeowners’ or other qualifying exemptions are subtracted.
3. Net Taxable Value Gross taxable value minus exemptions.
4. Annual Tax Rate Net taxable value is multiplied by the fiscal year’s adopted secured tax rate.
5. Direct Charges Add applicable direct charges and special assessments to reach total bill.
Bill formula: Net Taxable Value × Annual Tax Rate + Direct Charges / Special Assessments = Total Secured Property Tax Bill.
Why your calculation may not equal the bill: the annual rate is more than the basic Proposition 13 1% levy because voter-approved indebtedness can be included, and separate direct charges/special assessments can appear outside the ad valorem calculation.

Upcoming 2026–27 secured tax cycle

San Francisco Property Tax Due Dates

Annual Bill Mailing Secured real-property tax bills are normally mailed in October.
First Installment First installment becomes delinquent after 5:00 p.m. December 10.
Second Installment Second installment becomes delinquent after 5:00 p.m. April 10.
Fiscal-Year End Unpaid secured taxes reach tax-default status after June 30.
Redemption Charges Defaulted balances begin accruing additional redemption charges.
First installment penalty: a late first installment receives a 10% penalty. The second installment also receives a 10% penalty plus applicable additional charges when delinquent.
Current August 2026 position: the FY 2025–26 secured cycle has already passed its April 10 and June 30 milestones. The upcoming FY 2026–27 secured bill is expected in October 2026, with the first regular installment due December 10.

Miss first installment 10% penalty applies after the December 10 deadline.
Miss second installment 10% penalty plus applicable costs apply after April 10.
Still unpaid after June 30 Property becomes tax-defaulted and begins accruing additional redemption charges.
Defaulted secured tax: San Francisco states that tax-defaulted balances incur an additional 1.5% per month plus a redemption fee.
Get a live redemption amount. Do not manually add months of interest to an old bill and assume you have the correct payoff.
Business personal property

Business Property Uses a Different Tax Timeline

Business personal property is not the same as the secured real-estate tax on a home or commercial building. Equipment, fixtures and other taxable business assets can appear on the unsecured/business-property side of San Francisco’s system.

Assessment appeals The normal annual-roll business-property appeal period is also July 2 through September 15.
Late-mailed assessments Certain business-property assessments mailed after the regular filing period can carry a separate 60-day appeal rule.
Current August payment issue The Treasurer’s current calendar lists an August 31 business personal property tax payment deadline.
Do not use the secured December 10 / April 10 installment calendar for every business-property bill. Read the specific unsecured/business bill.
Recorded ownership and lien research

How to Search San Francisco Deeds, Deeds of Trust & Liens

The Recorder side of the Assessor-Recorder maintains the official recorded-document index. This is the correct place to trace legal conveyances rather than relying only on an assessment owner field.

Get the Block/Lot first. Use PIM or the tax bill.
Open the Recorder’s online search. Go to San Francisco Recorder Search.
Search by party name when tracing ownership. The index supports last, first and middle-name fields for primary and additional parties.
Narrow by document class/type. Useful categories include deeds, deeds of trust, reconveyances, liens, maps and other recorded instruments.
Use date or document-number ranges. Helpful when the transfer date is known.
Search Assessor Parcel Number when available. APN/Block-Lot can connect the document search back to the property.
Use book/page or address if needed. Older or differently indexed records can be easier to locate with recording references.
Read the actual instrument. The index tells you a document exists; the document itself contains the legal conveyance, lien, easement or security interest.
Assessment ownership is not a title report. For purchase, refinance, estate, lien-priority or easement questions, review the recorded instrument and use qualified title/legal professionals when needed.
Value research beyond the assessor card

Use Permits, Planning and Complaints to Explain Property Differences

Building Permits Check construction, remodel and permit history that may explain new value or building characteristics.
Planning Applications Review entitlement/project history for development-sensitive parcels.
Historic Status Preservation constraints can matter when comparing properties.
Complaints Complaint history can help explain property-condition or compliance issues.
Appeal tip: comparable sales are stronger when you explain why the comparable is truly similar. PIM’s permit, zoning and property-history tools can help identify major differences that a simple sale-price list misses.

Which San Francisco Property Records Should You Check?

Situation Records to review Best next action
Buying a condo PIM Block/Lot, tax bill, deed, deed of trust, permits and HOA/unit identification. Verify the exact condo lot, not only the building address.
2026 value seems too high Prop 13 base-year history, current value, comparable sales and condition evidence. File AAB appeal by September 15, 2026.
Market value fell Factored base-year value vs January 1 market value. Evaluate Prop 8 decline-in-value evidence.
Recently purchased property Recorded deed, new base-year assessment and supplemental tax bill. Do not assume October annual bill includes every supplemental tax.
Principal residence Homeowners’ Exemption and Prop 19 eligibility if applicable. Verify exemption is enrolled.
Parent-child transfer Prop 19 exclusion claim and principal-residence qualification. Do not assume automatic exclusion from reassessment.
Tax bill much higher than rate math Net taxable value, annual rate, direct charges and special assessments. Separate value-based tax from direct charges.
Need legal ownership Recorder deed and later recorded documents. Use Recorder search rather than PIM alone.

Title-specific answers

San Francisco Assessor Property Search FAQs

1. How do I search San Francisco County property records?

Use the San Francisco Property Information Map. You can search by street address, Assessor Block/Lot parcel number, planning application number or directly by clicking a parcel on the map. Once the parcel opens, save its Block/Lot because that identifier can be reused for assessment, tax and recorded-document research.

2. What is a San Francisco Block and Lot number?

The Block/Lot is San Francisco’s parcel identifier. A format such as 0787/001 means Assessor Block 0787 and Lot 001. It is one of the most reliable keys for matching Planning property data, the secured property-tax bill and Recorder records.

3. Who is the San Francisco County Assessor in 2026?

The official agency is the City and County of San Francisco Office of the Assessor-Recorder, headed by Assessor-Recorder Joaquín Torres. The office is in City Hall Room 190 at 1 Dr. Carlton B. Goodlett Place and currently lists 628-652-8100 as its main phone number.

4. What is the San Francisco 2026 property assessment appeal deadline?

The regular-roll formal assessment appeal filing period is July 2 through September 15. As of August 12, 2026, the window is open. The Assessment Appeals Board currently charges a $60 nonrefundable filing fee, and the application and payment must be successfully received by the filing deadline.

5. How does Proposition 13 affect San Francisco assessed value?

Proposition 13 generally establishes a base-year value at the 1975 value or after a later qualifying change in ownership or new construction. That base value is normally increased each year by no more than the lower of the California inflation factor or 2%, creating the factored base-year value. Special exclusions and temporary decline-in-value rules can change the enrolled result.

6. Can a San Francisco assessed value increase more than 2% in one year?

Yes. A temporary Proposition 8 decline-in-value assessment can increase by more than 2% when market value recovers, as long as it remains below the property’s Proposition 13 factored base-year value. Change in ownership or new construction can also establish new assessed value outside the ordinary annual 2% factor.

7. What is the San Francisco Homeowners’ Exemption?

A qualifying owner who occupies the property as a principal residence can receive up to a $7,000 reduction in taxable assessed value. February 15 is the normal deadline for receiving the full exemption on a first-time claim. Once approved, the exemption generally continues until ownership or principal-residence eligibility changes.

8. When are San Francisco secured property taxes due?

San Francisco normally mails secured real-property tax bills in October. The first installment becomes delinquent after 5:00 p.m. December 10, and the second installment becomes delinquent after 5:00 p.m. April 10. Property remaining unpaid after June 30 becomes tax-defaulted.

9. What are San Francisco’s current online property-tax payment fees?

The current secured-property-tax payment information lists no fee for eCheck. Credit-card and debit-card payments carry a 2.25% fee with a $2 minimum. A rejected eCheck is subject to a $50 returned-payment charge. San Francisco does not accept partial payments on secured tax bills.

10. Where can I search San Francisco deeds and liens?

Use the official San Francisco Recorder online search. It supports party-name searches, document class and type, filing code, date and document-number ranges, Assessor Parcel Number, book/page, address and property ID. Review the actual recorded instrument when legal ownership, a deed of trust, reconveyance or lien matters.

County Property Search, Homestead & Tax Help Toolkit

Use this free helper to find the right county office, prepare a property search, understand appraised value, review homestead exemption steps, and organize TRIM notice or tax bill questions before using official county websites.

Built for Florida county property guides
Helps users find official resources
No fake database or approval claim
Useful after every article

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.
