California has no statewide business license across its 482 incorporated cities. Learn how to use CalGold to find your exact city, county, and state rules.
Most business owners start searching for licenses through their city's website, then their county's, trying to make sure they don't miss anything.
California actually built a free lookup tool for exactly this problem. It takes your business type and address and returns the exact city, county, state, and federal permits that apply to you.
From there, the pieces that come up most often are a city business tax certificate, a seller's permit if you sell tangible goods, and a professional license if your trade is regulated by the Department of Consumer Affairs.
This guide walks through how to use CalGold, what each piece actually costs, and the specific rules for Los Angeles, San Diego, San Francisco, and Chula Vista.
Key Takeaways
There is no single statewide license in California every business must get. Requirements are set entirely by your city, county, and industry.[1]
The California Governor’s Office of Business and Economic Development runs a free lookup tool that generates a checklist of every city, county, state, and federal permit tied to your specific business type and address.[1]
The CDTFA seller’s permit has no application fee and no fixed expiration date. Remote sellers only need one once combined California sales exceed $500,000 in the current or prior calendar year.[2][3]
As of January 1, 2025, under Assembly Bill 2622, unlicensed handypeople can legally take on jobs under $1,000 in combined labor, materials, and other costs, up from the old $500 threshold, but only if the job needs no building permit and they don't hire help. [4]
California’s statewide penalty is for contracting without a license, starting at up to $5,000 and 6 months in jail for a first offense.[12]
What Is a Business License?
A business license is official permission from a government body to legally operate in a specific place or profession. In most states, this comes from one office. In California, "business license" is really shorthand for a bundle of separate requirements:
- A city business tax certificate
- A county permit if you’re outside city limits
- A CDTFA seller’s permit if you sell tangible goods
- A state board license if your profession is regulated
None of these are the same as forming your business entity. An LLC or corporation is registered once with the Secretary of State and creates your legal structure; your city, county, seller’s permit, and any professional license are separate steps you complete after formation, and several of them renew every year.
Do You Need a Business License in California?
In most cases, yes! This applies regardless of entity type, including a sole proprietorship operating under the owner’s own name. Because there is no single statewide license, use this breakdown to identify which of the following actually apply to you.
- City business tax certificate: Required by nearly every incorporated California city for businesses operating or based there, regardless of size.[7][9][10]
- County permit: Required instead of a city certificate if your business operates in an unincorporated area, and separately for specific regulated activities like food service.[1]
- CDTFA seller’s permit: Required if you sell or lease tangible personal property that would normally be subject to sales tax, even temporarily or seasonally.[2]
- State professional or occupational license: Required for regulated trades and professions overseen by roughly 40 boards and bureaus under the Department of Consumer Affairs.[5]
- Contractor’s license: Required for most construction trade work above the small-jobs exemption threshold, which increased to $1,000 in combined labor, materials, and costs on January 1, 2025, provided the job needs no building permit and the person works alone.[4]
- Freelancers and independent contractors: Still need whatever city or county license applies to where you work, even if you formed an LLC for liability protection.
- Home Occupation Permit: Required by most cities if you run the business from a residence, in addition to whatever city or county license already applies. Federal license: Required only if your business operates in a federally regulated industry, such as alcohol, firearms, or transportation. [13]
Step-by-Step: How to Get a California Business License
Step 1: Register Your Business Entity
Form your LLC or corporation with the California Secretary of State, or file a Fictitious Business Name (DBA) statement with your county clerk if you are operating as a sole proprietor under a trade name. Before you file, run your proposed name through our business name generator to confirm it’s available. This step creates your legal structure; it does not satisfy any city, county, or seller’s permit requirement.

Step 2: Get an EIN
Most banks, city licensing offices, and the CDTFA will ask for a federal Employer Identification Number (EIN) before you can open a business account or register for a permit. An EIN is free directly from the IRS.

Step 3: Look Up Your Exact Requirements on CalGold
Before applying anywhere, run your business type and address through CalGold, the state’s free permit assistance tool. It returns a checklist of the specific city, county, state, and federal permits tied to your business, which is the fastest way to avoid missing a requirement in a state with no single general license.
Step 4: Apply for Your City Business Tax Certificate
Apply directly with your city’s finance or treasurer’s office. Fees and forms vary by city: some price by gross receipts, others by employee count or a flat schedule. See the city-by-city breakdown below for Los Angeles, San Diego, San Francisco, and Chula Vista specifically.[7][9][10][11]
Step 5: Check County-Level Requirements
If your business sits in an unincorporated area, your county, not a city, issues your business permit. Counties also separately regulate activities like home-based food production; see the Cottage Food Program section below.[1]
Step 6: Register for a Seller’s Permit, If Applicable
If you sell or lease tangible goods, register for a seller’s permit through the California Department of Tax and Fee Administration. It’s free, has no fixed expiration date, and can be completed online. Remote sellers with no physical presence in California only need one once statewide sales exceed $500,000 in the current or prior calendar year.[2][3]

Step 7: Apply for State Professional or Contractor Licensing, If Applicable
Check whether your profession is regulated by one of the roughly 40 boards under the Department of Consumer Affairs, or whether your trade work requires a CSLB contractor license. Remember the small-jobs exemption only covers work under $1,000 in combined labor, materials, and costs, and only when no building permit is required, and the person doesn't hire help. [5][4]
Step 8: Renew Everything on Its Own Schedule
City business tax certificates typically renew annually, often by a specific calendar date such as San Francisco’s end-of-February deadline. Seller’s permits do not expire on a fixed schedule but must stay current with your actual business activity. Track each renewal separately since they rarely align.
Business License Requirements by City
City | Requirement | Additional Details |
Los Angeles | Business Tax Registration Certificate (BTRC) required for anyone conducting business "with the object of gain, benefit, or advantage" within city limits.[7] | Tax is based on gross receipts and business category. Already-registered businesses with $100,000 or less in taxable and nontaxable gross receipts qualify for a Small Business Exemption.[8] |
San Diego | Business Tax Certificate required for all businesses operating in the city.[9] | $34 flat fee for 12 or fewer employees; $125 plus $5 per employee for 13 or more, plus a $4 state-mandated accessibility fee on every application or renewal.[9] |
San Francisco | Business Registration Certificate required through the Office of the Treasurer & Tax Collector within 30 days of starting business in the city.[10] | Fee is based on projected gross receipts; the First Year Free program waives the first registration fee for many businesses. Renews annually by the end of February.[10] |
Chula Vista | Business license required under the city’s Master Tax Schedule before operating.[11] | Requires a physical street address; P.O. boxes are not accepted. Fees follow Chapter 5.07 of the municipal code rather than one flat rate.[11] |

County-Level Licensing and California’s Cottage Food Program
Businesses based in unincorporated areas register with their county rather than a city. Separately, home-based food production runs on its own statewide framework, the Cottage Food Program, but the actual registration or permit is issued and administered at the county level, not through one central state portal.
- Statewide framework: the California Homemade Food Act sets two operating classes, Class A (direct sales only) and Class B (direct and indirect sales), and a statewide gross annual sales cap.[14]
- San Diego County: cottage food registration and permitting are handled by the Department of Environmental Health and Quality.[15]
- Riverside County: the Department of Environmental Health processes cottage food registration and permitting for home-based kitchens countywide.[16]
- Stanislaus County: Environmental Resources administers Class A and Class B cottage food packets and renewals separately from any city business license.[17]
Because each county runs its own intake, always confirm the current packet, fee, and renewal cycle directly with your county’s environmental health department rather than assuming statewide rules alone will cover local requirements.
What a Local Business License Actually Costs
There is no single number to budget around. City fee structures range from flat rates to gross-receipts tiers, and several cities offer exemptions or waivers most guides never mention. A few concrete data points:
- Los Angeles: Based on gross receipts and category, with a full exemption for already-registered businesses at $100,000 or less.[8]
- San Diego: $34 flat for 12 or fewer employees, $125 plus $5 per employee for larger businesses, plus a $4 accessibility fee.[9]
- San Francisco: Priced by projected gross receipts, but many new businesses pay nothing at all in year one under the First Year Free program.[10]
- Seller’s permit: Free through the CDTFA regardless of business size, unless you are a remote seller under the $500,000 threshold and therefore don’t need one at all.[2][3]
California Business License Cost Breakdown
Item | Typical Cost |
California LLC or corporation formation | Filed with the California Secretary of State; fee varies by entity type |
EIN (federal tax ID) | Free, directly from the IRS |
City business tax certificate | Varies by city: roughly $34 to several thousand dollars depending on gross receipts, employees, or category[7][9][10] |
County permit (unincorporated areas) | Varies by county; look up your exact fee through CalGold[1] |
CDTFA seller’s permit | Free, no application fee[2] |
State professional or contractor license | Varies by board or trade; contact the relevant licensing board for current fees[5][4] |
Penalty for unlicensed contracting | Up to $5,000 fine and up to 6 months in jail for a first offense, rising sharply for repeat offenses[12] |
Penalties for Operating Without a Required License
California does not have one general statewide statute penalizing every unlicensed business, since there is no single general license to violate. The clearest, fully codified statewide penalty applies specifically to contracting work performed without a required CSLB license. Cities and counties separately enforce their own local business tax and permit violations.
Offense | Penalty |
First offense (unlicensed contracting) | Fine of up to $5,000, up to 6 months in county jail, or both.[12] |
Second offense (unlicensed contracting) | Fine equal to the greater of 20% of the contract price or aggregate payments, or $5,000, plus a minimum 90 days in county jail.[12] |
Third or subsequent offense (unlicensed contracting) | Fine between $5,000 and the greater of $10,000 or 20% of the contract price, plus 90 days to 1 year in county jail.[12] |
Operating without a required city or county business license | Varies by jurisdiction; contact your city or county directly for its current enforcement and penalty policy. |
California Business License vs. Business Registration
These are separate filings with different agencies, and most active California businesses need both.
Business Registration | Business License |
Creates your legal entity (LLC, corporation, or DBA) through the Secretary of State’s bizfile Online portal [6] | Grants permission to actually operate in a specific city, county, or regulated profession |
Filed once at formation, then maintained with periodic state filings like the Statement of Information | City certificates typically renew annually; seller’s permits and professional licenses each run on their own separate cycle |
Filed with the California Secretary of State | Filed with your city, county, the CDTFA, or the relevant state licensing board |
Forming an LLC does not automatically satisfy any city, county, or seller’s permit requirement, and vice versa. If you’re just getting started, see our guide to starting a business, and confirm you’ve appointed a registered agent if your entity requires one.
