San Francisco, CA Business License Guide 2026

San Francisco Business Registration Certificate

San Francisco’s main local registration is the Business Registration Certificate. Current city law generally gives a person 30 days after commencing business in San Francisco to apply. Use the Treasurer & Tax Collector’s current registration page.

Have your legal name, ownership or entity information, addresses, business activity, start date, and estimated San Francisco gross receipts ready. Report locations and FBN/DBA names as the current application requires.

Important correction: some broader city pages still show an older 15-day deadline. The current registration page and municipal code say 30 days.

Renewal timing changed in 2026

Beginning in 2026, registration renewal is due on the last day of February through the unified Annual Business Registration and Tax Form. The 2025 tax year and 2026-27 form was due March 2, 2026 because February ended on a weekend. The registration year generally runs April 1 through March 31.

Renewal does not replace any separate tax return, payment, license, or permit that applies to your business.

Costs you can plan for

Costs vary by receipts, location, construction, and regulated activity. Do not budget from an old flat “business license fee.” Check the current fee page for each filing.

First Year Free: the July 2026 extension runs through June 30, 2027, or until reimbursement funds run out. Current eligibility generally includes a new business or new location beginning on or after July 1, 2023, no more than $5 million in estimated or reported San Francisco gross receipts, and a registered commercial-use location. Home-based businesses and short-term rentals are excluded. The program waives only covered fees.

Zoning, buildings, health, fire, and other local permits

Check zoning before signing a lease. San Francisco’s zoning for businesses page explains how to check whether your use fits the address. A Business Registration Certificate does not override zoning or permit conditions.

Home-based businesses

A home office or online business can still need city registration and must fit Planning Code rules for activity in a dwelling. Current Section 204.1 limits floor area, nonresident workers, stock, displays, and public-facing activity; its general accessory-use rule allows no more than two workers who do not live there, subject to exceptions. Use the city’s home-based business guide and your exact address. Cottage food, child care, massage, short-term rentals, and other special activities have separate rules. See also home occupation permits explained.

Licensed small family day care homes: California Health and Safety Code Section 1596.803 says a local jurisdiction may not impose a business license, fee, or tax for the privilege of operating a licensed small family day care home. State child-care licensing and other applicable rules still apply. See the current California statute.

Building permits, occupancy, and signs

Remodeling, new equipment, storefront work, or a change in use can trigger permits. Start with building permits for business and the Permit Center. For permits issued through PermitSF, use the current inspection page. For applications filed on or after June 21, 2026, see the city’s current permit application timelines.

Do not assume every sign needs a permit. A reform effective August 31, 2025 removed permits and fees for many common facade, window, door, and interior business signs; other signs can still require review. See the PermitSF legislation summary.

Food, mobile food, and temporary food

Fixed restaurants, bars serving food, retail food locations, mobile vendors, and temporary-event food sellers follow different paths. Fixed retail food businesses should start with the city’s retail food health-permit route.

For mobile food, Ordinance 49-26 took effect May 11, 2026 and separates Compact Mobile Food Operations from other Mobile Food Facilities. Public Works handles public-right-of-way location permitting, while DPH and Fire handle their parts of safety review. Start with Public Works Mobile Food Facilities and the DPH route for your setup. BLG’s food truck permit guide explains the broader layers.

Temporary-event and farmers’ market food sellers may instead need a Temporary Food Facility route, depending on how food is prepared and sold.

Alcohol, short-term rentals, and regulated work

Alcohol requires the applicable California ABC license; use ABC’s online application route. Short-term rental hosts should use the Office of Short-Term Rentals; a Business Registration Certificate does not replace host certification. Contractors should verify state licensing through CSLB. Ongoing live entertainment may also need an Entertainment Commission permit.

Watch January 1, 2027: ABC says application and annual license fees will increase 3.31%. Use the 2027 schedule if your filing crosses that date.

Permit Center help

If several departments may be involved, use Permit Center business services with your exact address and planned activity.

Fictitious Business Name, DBA, and public business names

A Fictitious Business Name (FBN), often called a DBA, is separate from the Business Registration Certificate. The San Francisco Office of the County Clerk handles the local FBN filing when required.

Start with the city’s FBN filing guide and current statement page. Follow the County Clerk’s current filing, signature, fee, and publication instructions. Registering an LLC, domain name, or social-media account does not complete an FBN filing.

California state and federal steps

San Francisco registration is local. It does not form an entity, issue a seller’s permit, register an employer with EDD, grant a professional license, or replace federal tax steps.

California Secretary of State

For corporations, LLCs, limited partnerships, and other state-filed entities, use the Secretary of State’s Business Entities resources and bizfile Online. Effective August 1, 2026, web User Access is required for online Statement of Information filings; see the current filing tips.

Seller’s permit and state tax accounts

If you sell or lease tangible personal property that would ordinarily be taxable at retail, check CDTFA. Use the state’s seller’s permit service and CDTFA online registration. A seller’s permit is not the city Business Registration Certificate; see seller’s permit vs business license.

Employers and professional licenses

EDD says a commercial employer generally must register within 15 days after becoming a subject employer; for a business, that includes hiring employees and paying more than $100 in wages in a calendar quarter. Use EDD employer registration. New or rehired California employees must also be reported to the New Employee Registry within 20 calendar days of their start date.

For regulated work, use the actual licensing board. The DCA license search, CalGOLD, and CSLB can help route common state-license questions.

Federal steps

Use the IRS EIN page when an EIN is needed. For federally regulated activities, use the responsible federal agency; the SBA licenses and permits overview is a useful map.

BOI: FinCEN finalized its rule on August 11, 2026. U.S. companies remain exempt from BOI reporting; only certain foreign companies registered to do business in the United States remain reporting companies. See FinCEN’s current quick reference. This final rule made permanent a practical exemption that already existed before this review window.

What does this mean for me?

Start with the local Business Registration Certificate, then add only the layers that match your address, business activity, ownership structure, sales, and employees. Registration is not zoning approval, an FBN is not a license, and a seller’s permit is a separate state tax permit.

For a storefront, check the location first because zoning, construction, food, fire, sign, or occupancy issues can affect the opening path. For a home-based, freelance, or online business, the permit stack may be shorter, but city registration and any activity-specific rules still need to be checked. If you hire, sell taxable goods, use a public trade name, or work in a licensed profession, add those separate state or local steps.

Real-world examples

A compact compliance checklist

• Confirm the exact activity and San Francisco address or service area.
• Check zoning before signing a lease or opening to customers.
• Apply for the Business Registration Certificate within the current 30-day rule.
• Check whether your public business name needs an FBN filing.
• Route building, fire, health, sign, mobile-food, entertainment, and public-right-of-way issues to the controlling department.
• Check Secretary of State filings and bizfile access if you use a state-filed entity.
• Check CDTFA for taxable sales and EDD for employees and new-hire reporting.
• Check the correct California board for regulated work and the IRS for EIN needs.
• Save permits, confirmations, receipts, and renewal dates.

What to do if this doesn’t work

If a portal rejects your filing, save the error and use that system’s help route. If official pages conflict, start with current law or code and the current page of the office controlling the filing: Treasurer & Tax Collector for registration, County Clerk for FBN, Planning for zoning, DBI for building, DPH for health, Public Works for right-of-way permits, and the relevant state agency for state licenses.
