What happens at a San Francisco Assessment Appeals Board hearing?

A San Francisco Assessment Appeals Board hearing is a quasi-judicial session where you and the Assessor each present evidence of January 1 market value. The Board is independent of the Assessor. You get at least 45 days' notice. The Board has up to two years from a timely filing to hear and decide. For an owner-occupied single-family principal residence, the Assessor presents first. The Board may decrease, confirm, or increase the enrolled value.

It is not a courtroom, and you are not required to have a lawyer (Publication 30). It is also not a conversation you already had with the Assessor's staff. Only evidence presented at the hearing counts. AppealKit is a flat-fee packet tool; you still attend, and this is not legal advice.

Who is the Assessment Appeals Board, and where do they sit?

The Assessment Appeals Board is an independent agency, separate from the Assessor's Office, established to equalize taxable property values in the City and County of San Francisco (AAB). It sits at 1 Dr. Carlton B. Goodlett Place, City Hall, Room 405. Phone (415) 554-6778.

The Board meets Monday through Friday in two sessions, 9:30 a.m. and 1:30 p.m., and stays until the calendar is finished. There are three panels with different subject-matter authorizations: Board 1 may hear appeals regardless of value, type, or location; Boards 2 and 3 have published limits by value, property type, and assessor's-block geography. Residential owners of four units or fewer often see Board 3. Do not assume your hearing is remote unless the notice says so.

After a complete, timely application, staff send an acknowledgement with a file number and a fee receipt. You then typically hear nothing until the hearing notice. The Assessor receives a copy of the application. Many files resolve before a hearing by a written stipulation signed by you (or your agent), the Assessor, and county legal counsel. If a stipulation is signed, you do not need to appear; if it is not, you do (Publication 30; AAB FAQs).

Hearing officer or full Board panel — which one am I in?

San Francisco offers a hearing officer program for single-family dwellings, condominiums, cooperatives, or multi-family buildings of four units or fewer. All commissioners can sit as hearing officers. The session is less formal, in front of one commissioner. Hearing fees do not apply to hearing-officer cases (AAB fees; information page).

Bring three sets of the documents you will rely on. For an owner-occupied single-family residence or condominium, the Assessor presents first. You then state your opinion of value and the facts behind it. Each side may question the other. The officer usually recommends a value at the end. Either you or the Assessor has 14 calendar days to reject that recommendation in writing. A timely rejection puts the case on a three-member Board panel for a new hearing. Findings of fact are not available after a hearing-officer proceeding.

If you do not elect a hearing officer, the case is set for a Board hearing and the hearing-fee schedule applies for properties assessed above $250,000 ($100 in the $250,001–$2,000,000 band). A Board hearing is a three-member panel. Bring six sets of documents (the information page's hearing-prep section; an earlier paragraph on the same page says five — bring six and you are covered). An oath is administered. The clerk decides who has the burden of proof, which decides who opens. Cross-examination and closing summaries are allowed. The panel may decide on the spot or take the matter under submission and mail a decision later. A Board decision is final at the local level.

What is the burden of proof at an SF hearing?

The Assessor bears the burden — and opens — in these situations (Publication 30; AAB information page):

  • Owner-occupied single-family dwellings that qualify for the homeowners' exemption (your principal residence).
  • The Assessor enrolled a value different from the purchase price (if you filed a Change in Ownership Statement on time).
  • Escape assessments (with the usual filing-exceptions).
  • The Assessor wants a higher value than the current roll.
  • Penalty assessments the Board has jurisdiction to remove.

In every other situation — including a vacation home or a non-owner-occupied building — you have the burden and you present first. Burden of proof is not a substitute for comparable sales. Even when the Assessor opens, a silent applicant still loses if the only evidence in the room is the Assessor's.

What evidence should I bring — and what will the Board ignore?

Bring the grid: closed sales timed to January 1, adjusted, with addresses and parcel numbers, plus photographs if condition is part of the story. Publication 30's comparison worksheet is the state's own template. An appeals board may not consider comparable sales more than 90 days after the valuation date (BOE FAQs). Informal-review printouts from March are not automatically in the Board file; if you want them considered, put them on the table.

The Board will not consider:

  • Anything attached to the application, or emailed to the Assessor, unless you also present it at the hearing.
  • Depositions.
  • A neighbor's lower assessment, standing alone. California residential appeals are market-value cases, not equal-and-uniform protests.
  • Ability to pay, or a request to lower the tax rate. The Board cannot grant exemptions, fix rates, or reduce taxes because the bill is hard (AAB FAQ; Pub 30).

A formal appraisal is allowed; the Board may require the author to attend and answer questions. Realtors' opinion letters have the same exposure. Exchange of information is optional for you at any value, and available to the Assessor when the assessed value is at least $100,000: request at least 30 days before hearing with your opinion of value and supporting data; the other side answers at least 15 days out. After an exchange, surprise exhibits can draw a continuance.

Can the Board raise my assessment? What if I miss the hearing?

Yes, the Board can increase the enrolled value based on the evidence. That is why a thin case belongs in the free informal review, which cannot raise you, and not in a formal hearing you are unprepared for.

If you or an authorized representative fail to appear, the application is denied for nonappearance and closed. You may file a written request for reconsideration within 30 days of the denial notice; those requests are for extraordinary circumstances, not a second bite (AAB FAQ). If you need a postponement, San Francisco publishes a request form and wants it at least 14 days in advance, with a waiver agreement. A spouse, parent, or child may appear for you without being an "agent." Anyone else needs written authorization; a California-licensed attorney does not.

You must keep paying the Treasurer. December 10 and April 10 do not move. A later reduction is a refund with interest (BOE FAQs; Treasurer).

How do findings of fact, refunds, and Superior Court work?

If you think you may take an adverse decision to San Francisco Superior Court, request written findings of fact before the Board hearing starts — on the application, in writing to the clerk, or orally on the record. The fee is $430 per hour, one-hour deposit, maximum 30 hours. Findings are not available after a hearing officer. You can withdraw the request before a decision and recover the deposit; the other party may then pick it up (AAB fees).

Checking the application's claim for refund box lets the county process a refund automatically if you win. It also shortens the Superior Court clock: you would have six months from the Board decision to file in court. Leaving the box unchecked means a separate refund claim with the Board of Supervisors and a longer path. The information page walks through both. A Board decision is not reheard by the Board. Court is the next forum, and you will want the findings plus a transcript.

Hearing fees on a full panel, when they apply, are due 30 days before the hearing. Half comes back if the value is reduced to your opinion of value or by 30% or more, if you request that refund in writing within 30 days of the decision. Withdraw in writing 30 days before the hearing to recover the hearing fee; the $120 application fee stays.

The free check will not sit at the table for you. It will tell you whether the January 1 comps are strong enough to belong in that room. Neighborhood does not change the procedure: Noe Valley and the Mission use the same Board.

What does the residential hearing actually feel like, minute to minute?

Arrive early enough to watch someone else's case if the room is public and the calendar allows it — Publication 30 recommends sitting in, and San Francisco hearings are open. When your file is called, you sit at the table. An oath is administered. The clerk confirms who has the burden of proof.

If this is your principal residence, the Assessor's representative opens with their opinion and their comps. Listen for the three tests: arm's-length, physical similarity, timing. A sale from the wrong named neighborhood, a listing rather than a closing, or a closing after April 1 is fair game to question. Then you put your grid down — six copies at a Board hearing, three at a hearing officer — and walk through three to five adjusted sales, not a speech about the tax bill. Stay on January 1 market value. The Board cannot lower the rate, grant an exemption, or reduce taxes because last year was cheaper (AAB information page).

Each side may question the other. Keep it about the exhibit in front of the panel. A stipulation you almost signed last week is not evidence unless it is in the room as a signed stipulation. If the Assessor surprises you with a new sale that was not in an exchange of information, you may ask for a continuance.

The panel may rule before you stand up, or take the matter under submission. Either way, keep paying December 10 and April 10. The comps guide is what you should have printed before you walked in; this section is only the choreography.

FAQ

What happens at a San Francisco Assessment Appeals Board hearing?

You and the Assessor present evidence of value to a hearing officer or a three-member panel. The Board decides based only on what is presented that day and may lower, confirm, or raise the enrolled value (sf.gov AAB; BOE FAQs).

Do I need an attorney?

No. You may represent yourself. Family members and California-licensed attorneys do not need a separate agent authorization; other agents do (Publication 30).

How much notice will I get?

At least 45 days before the first hearing. Subsequent dates, if the first is vacated, may be noticed on as little as 10 days (BOE FAQs; AAB information page).

How long can the Board take?

Up to two years from a timely filing to hear and decide. If that clock runs out, your opinion of value may temporarily become the enrolled value until a decision, with exceptions (BOE FAQs; Publication 30).

Is a hearing officer's decision final?

Not in San Francisco if either side rejects it in writing within 14 days. The case then goes to a three-member panel (AAB information page).

What if I miss my hearing?

The application is denied for nonappearance. You have 30 days from the denial notice to request reconsideration for good cause (AAB FAQ).

Can the Board increase my assessment?

Yes. Based on the evidence, it can decrease, confirm, or increase the value (BOE FAQs).

Do I still pay my tax bill?

Yes. December 10 and April 10 remain in force. A win is a refund with interest, not a pause (Treasurer; BOE FAQs).
