City business license guide
Last updated: April 28, 2026
Starting a business in San Francisco usually means more than one step. The city has local registration, and your business may also need state tax accounts, entity filings, zoning review, building permits, health permits, fire review, or other approvals.
\n
Bottom line
If you operate a business in San Francisco, you generally need to register with the San Francisco Office of the Treasurer & Tax Collector. San Francisco calls this a Business Registration Certificate, not just a general business license. The city says businesses engaging in business in San Francisco must register, and the Treasurer & Tax Collector says registration is required within 15 days after starting business in the city.
That registration does not replace zoning, health, fire, building, seller’s permit, employer, state professional license, or federal rules. A restaurant, food truck, salon, contractor, short-term rental host, retailer, or home-based business may have extra steps. Start with the city registration page, then check zoning and business-type permits before you sign a lease, buy equipment, or advertise an opening date.
Quick start for San Francisco business owners
- Write down your business type, address, ownership structure, start date, and whether customers will visit the location.
- Use the city’s starting a business guide to map the main city steps.
- Check whether your activity is allowed at the address through the city’s zoning for businesses page before you commit to a site.
- Register with the San Francisco Treasurer & Tax Collector through the official register a business page.
- If you use a public business name that is not your exact legal name, check the city and county Fictitious Business Name process.
- Check California state accounts, including the Secretary of State, CDTFA, EDD, and any professional board that fits your work.
- Ask the Permit Center or Office of Small Business about local permits if your business involves food, building work, signs, public space, entertainment, vehicles, or public health rules.

City, county, state, and federal layers
Business licensing is layered. One approval does not usually cover every other approval. In San Francisco, the city and county are the same local government, but different offices handle different filings.
| Layer | What it may cover | Where to check |
|---|---|---|
| City | Business Registration Certificate, local business taxes, zoning, building, fire, health, public space, signs, and some business permits. | SF Treasurer & Tax Collector, SF Planning, Permit Center, DBI, DPH, Fire, Public Works, and other city departments. |
| County | Fictitious Business Name filing and related county clerk records. | San Francisco Office of the County Clerk. |
| State | California entity filings, seller’s permit, employer payroll tax account, professional licenses, and state tax rules. | California Secretary of State, CDTFA, EDD, DCA boards, and CalGOLD. |
| Federal | EIN, federal tax duties, federal permits for regulated activities, and current BOI rules when they apply. | IRS, SBA federal license list, and FinCEN. |
| Private platforms | Marketplace, payment app, delivery app, or landlord rules. | Your platform, lease, processor, or contract. These do not replace government rules. |
For a broader plain-English comparison, see city, county, and state licenses. If you are still unsure which item is which, this guide on license, LLC, DBA, and seller’s permit may help you sort the terms before you apply.
San Francisco Business Registration Certificate
San Francisco’s main local requirement is the Business Registration Certificate. The city says businesses that operate in San Francisco must register. The Treasurer & Tax Collector page says every person engaging in business within the city must register within 15 days after starting business in San Francisco.
Use the official business registration page and the Treasurer & Tax Collector’s business registration portal. Have your legal name, public business name, owner information, address, business activity, entity type, estimated or actual San Francisco gross receipts, and start date ready. The exact fields can change, so follow the current portal.
Do not treat the certificate as a full permit to open any kind of business at any location. It is a city tax and registration step. Your location, build-out, signs, food service, public sidewalk use, and regulated work may still need separate review.
Renewal timing changed in 2026
Older San Francisco pages may still mention a May 31 renewal date. As of this update, the Treasurer & Tax Collector’s renew business registration page says that beginning in 2026, business registration renewal is due on the last day of February and is part of one unified Annual Business Registration and Tax Form. The official Annual Business Registration and Tax Form page says the 2025 return and 2026-2027 renewal were due on or before March 2, 2026.
Practical warning: San Francisco’s business tax and renewal pages can change by tax year. Use the current Treasurer & Tax Collector renewal page before relying on an old date from a saved PDF, blog post, or prior-year notice.
Costs you can plan for
San Francisco costs depend on your business type, location, receipts, payroll, and permits. Use official fee pages and current application screens before you budget.
| Cost area | Why it may apply | Where to confirm |
|---|---|---|
| Business registration | Most businesses operating in San Francisco need a local registration. Fees can depend on the city’s current tax and registration rules. | SF Treasurer & Tax Collector registration and renewal pages. |
| Local business taxes | Some businesses may owe San Francisco gross receipts or other local business taxes. | Official taxes and fees page. |
| First Year Free waiver | Qualifying new or expanding businesses may have some initial city fees waived. | Official First Year Free page. |
| Building or inspection permits | Build-outs, remodels, electrical, plumbing, mechanical, and other construction work may need permits. | Department of Building Inspection and Permit Center. |
| Food, health, or environmental permits | Restaurants, bars, food trucks, markets, and other health-regulated businesses may need health permits. | SF Department of Public Health Environmental Health Branch. |
| Fictitious Business Name | You may need this if your public business name is not your legal name. | Office of the County Clerk FBN pages. |
| State filings and licenses | LLCs, corporations, sellers of taxable goods, employers, and licensed trades may need state accounts or licenses. | California Secretary of State, CDTFA, EDD, and state licensing boards. |
First Year Free was extended through June 30, 2026, but not every business qualifies. Check the current city page before counting on it.
Zoning, buildings, health, fire, and other local permits
Check zoning before you sign a lease. San Francisco says every location has zoning laws that decide what kind of business can open there. The Planning Department enforces the Planning Code and issues certain permits. If your use is not allowed at the address, a business registration certificate will not fix that problem.
Use the city’s zoning for businesses page and ask for help before making a large payment. This matters for storefronts, food businesses, entertainment, manufacturing, personal services, cannabis, alcohol-related uses, auto uses, and some home-based operations.
Home-based businesses
A home office or online business can still have local rules. San Francisco has a home-based business guide from the Office of Small Business. Check it if you work from home, sell online from a San Francisco address, do gig work, make food at home, or see customers at your home. For a general background page, see home occupation permits.
Building permits and inspections
If you remodel, change walls, add equipment, change plumbing, add electrical work, install signs, or change how a space is used, building permits may matter. The city’s building permits for business page says the departments that often sign off on business location changes include the Department of Building Inspection, the Fire Department, and the Department of Public Health if food is served. The DBI permit services page explains building, electrical, plumbing, mechanical, and other construction-related permits.
Food and health permits
If you open a restaurant, bar, food truck, market, commissary, or other retail food facility, check the Department of Public Health before you open. San Francisco’s page for a retail food health permit says you must have a health department permit to open and run a retail food facility in San Francisco. The city’s health permits and regulations page can also point you to Environmental Health Branch permits.
If your business is mobile food, start with the local city process and also read our food truck license guide for the usual permit stack.
Permit Center help
The San Francisco Permit Center and Office of Small Business offer business permit help. The city’s Permit Center business services page lists business help and a current contact email. Use it if you are not sure which department should review your business.
Fictitious Business Name, DBA, and public business names
A Fictitious Business Name is often called a DBA. You may need it when your business uses a public name that is different from the legal name of the owner or entity. In San Francisco, this is handled through the Office of the County Clerk, not the Treasurer & Tax Collector.
Start with the city’s file a Fictitious Business Name page. The city’s FBN filing instructions also say a copy of the Business Registration Certificate or Temporary Verification of Registration is required for new accounts and certain changes. Use the official FBN statement filing page for the current filing method, fee instructions, signature rules, and publication steps.
Do not assume registering an LLC, getting a domain name, or opening a social media page means your San Francisco DBA step is done. These are different things.
California state and federal steps
San Francisco registration is local. It does not create an LLC, issue a California seller’s permit, register you as an employer, or issue a state professional license.
California Secretary of State
If you form a corporation, LLC, limited partnership, or certain other entities, check the California Secretary of State. The Secretary of State’s Business Entities section handles many business entity filings. You can also use bizfile Online for many filings and records. A sole proprietor may not need a Secretary of State entity filing just because they have a San Francisco business registration, but the facts can vary.
California seller’s permit and tax accounts
If you sell or lease tangible personal property in California that would normally be subject to sales tax, check the CDTFA. The CDTFA page on obtaining a seller’s permit says both wholesalers and retailers may need one when they are engaged in business in California and intend to sell or lease taxable tangible personal property. The CDTFA online registration page says online registration is free to use, though some permits, licenses, or accounts may require a fee or deposit.
For a simple comparison, see seller’s permit versus business license.
California employer and professional license checks
If you hire workers, check the California Employment Development Department. EDD says businesses that employ one or more employees must register as an employer and set up a payroll tax account within 15 days of paying more than $100 in wages in a calendar quarter. Start with EDD’s payroll tax registration page.
Some work also needs a state professional license. Examples can include contractors, barbers, cosmetology, health professions, real estate, security, accounting, and other regulated work. Use California’s DCA license search and the state CalGOLD permit tool to find official agencies for your business type.
Federal steps
Many businesses need an EIN from the IRS, especially if they hire employees, operate as a partnership or corporation, or have certain federal tax filing duties. Use the IRS page to get an EIN and avoid paid look-alike sites when the IRS option fits your situation.
Most small businesses do not need a federal operating license, but some activities are federally regulated. The SBA page on licenses and permits lists federal license areas such as alcohol, aviation, firearms, fish and wildlife, transportation, and broadcasting.
Beneficial ownership reporting rules have changed. FinCEN announced an interim final rule removing BOI reporting requirements for U.S. companies and U.S. persons under the Corporate Transparency Act. Foreign reporting companies have different rules. Check the current FinCEN BOI update before assuming a filing is or is not required.
What does this mean for me?
If you work from home, start with city registration, home-based rules, state tax duties, and any professional license that fits your work. If you open a storefront, check zoning and permits before the lease. If you sell taxable goods, add a CDTFA seller’s permit check. If you are already operating, ask the Treasurer & Tax Collector how to correct your account instead of guessing.
Real-world examples
| Business | Likely checks | Why |
|---|---|---|
| Online seller working from home | San Francisco registration, home-based rules, CDTFA seller’s permit, FBN if using a public name. | Local registration can apply even without a storefront, and taxable goods can trigger a state seller’s permit. |
| Restaurant or cafe | City registration, zoning, building permits, DPH health permit, fire review, signs, state tax accounts, employer registration if hiring. | Food and location-based businesses have several local reviews before opening. |
| Freelance designer | City registration, FBN if using a trade name, home-based rules if working from home, EIN if needed for tax or banking reasons. | Service businesses may have fewer permits, but local registration can still apply. |
| Contractor | City registration, state contractor license check, local building permit rules for jobs, state employer rules if hiring. | Contracting is often tied to state licensing and project-level permits. |
| Food truck | City registration, health permits, mobile food rules, commissary or storage rules, parking or location rules, seller’s permit. | Mobile food businesses often need both health and local operating approvals. |

Phone and email scripts
Use short messages. Include your business type, address, start date, and whether customers visit the location. Do not ask the agency to give legal advice. Ask which official steps apply.
Script for the Treasurer & Tax Collector
Hello. I plan to operate a [business type] in San Francisco at [address or home-based]. My start date is [date]. Can you confirm whether I need a Business Registration Certificate, what information I should prepare, and which current renewal deadline applies for my tax year?
Script for zoning or the Permit Center
Hello. I am considering [address] for a [business type]. Customers will [visit / not visit], and I may need [signs / food service / equipment / remodeling]. Can you tell me what zoning, planning, building, fire, or other local permits I should check before signing a lease?
Script for the County Clerk FBN office
Hello. My legal name or entity name is [legal name], but I want to operate publicly as [business name]. I have or am applying for San Francisco business registration. Can you confirm whether I need a Fictitious Business Name filing and what current filing and publication steps apply?
Script for a food or health-regulated business
Hello. I plan to operate a [restaurant / food truck / packaged food / market / other food business] in San Francisco. Before I buy equipment or open, can you tell me which health permit, plan check, inspection, food safety, or facility steps I should complete?
Keep a copy of the reply. If an agency sends you to another department, ask for the exact office or page to check next.
What to do if this doesn’t work
If a portal rejects your application, take screenshots, save the error message, and use the official help link on that portal. Do not change your business activity just to pass a form if the new answer is not true.
If two pages give different instructions, use the office that controls the filing: Treasurer & Tax Collector for registration and renewal, County Clerk for FBN, DPH for health permits, and DBI for building permits.
