City business license guide
Last updated: October 7, 2026
This guide explains the main license, tax, zoning, permit, and registration steps to check before you start or run a business in Fontana, California. It is written for regular business owners, not lawyers.
Fontana has a local business license requirement. The city also reviews many businesses for planning, building, safety, public health, police, fire, or other approvals depending on the business type and location.
Bottom line
Most businesses operating in Fontana need a city business license or business tax certificate, even when the business is based elsewhere but works in Fontana. Start with the City of Fontana business license information and online business license portal.
The city license does not replace zoning, home-occupation review, county health or FBN filings, California tax or employer accounts, professional licensing, or an EIN when those apply.
Quick start for Fontana business owners
- Write down the business activity, address, ownership type, start date, and whether customers, employees, food, alcohol, signs, vehicles, or construction are involved.
- Confirm the address is inside Fontana; nearby unincorporated areas use county local rules.
- Start with the city business-license page, then check zoning and site approvals before signing a lease or buying equipment.
- Check county and state steps that match the activity, and save every approval and renewal date.
Fontana business changes: April 1–October 1, 2026
- County FBN fees changed July 1. San Bernardino County now lists $90 for an FBN filing and $2 for each additional FBN or registrant name. Use the current FBN page.
- bizfile Online access changed August 1. California now requires web User Access for online filings; Statement of Information filing is visible only after access is established. Start at bizfile.
Fontana business license facts box
| City | Fontana, California |
|---|---|
| County | San Bernardino County |
| Local name | The city uses “Business License,” “Business License / Tax Certificate,” and “Business Certificate Application.” |
| City office | Business Services / Business License, with other city reviews when the activity or site requires them. |
| Online start | Use the city’s new business license application. |
| Home businesses | Licenses tied to a home address are not accepted online; use the city’s home-business process. |
| Renewal | The city uses an annual license cycle. Follow the current renewal notice or portal for the exact expiration date. |
| Main warning | A city license is separate from tax, FBN, health, building, zoning, and professional approvals. |
City, county, state, and federal requirements are separate
A Fontana business can have more than one government layer. One approval does not replace another.
| Layer | What to check | Main role |
|---|---|---|
| City of Fontana | Business license / tax certificate, zoning, occupancy/building, signs, home occupation, food-truck TUP. | Local permission and site review inside city limits. |
| San Bernardino County | FBN, food and health permits, and local permits for unincorporated addresses. | County filings and public-health functions; county land-use rules outside incorporated Fontana. |
| California | Entity filings, seller’s permit, employer accounts, contractor, alcohol, and professional licensing. | State registrations, taxes, and regulated occupations or activities. |
| Federal | EIN and federal permits for regulated activities; BOI only where current FinCEN rules apply. | Federal tax and activity-specific requirements. |
City of Fontana business license or business tax certificate
The City of Fontana says the Fontana Municipal Code requires all businesses operating, not necessarily located, within the city to be properly licensed. The city also says businesses must meet Planning zoning standards, Building and Safety standards, and Public Health rules.
The city uses the words Business License / Tax Certificate. The city still hosts a paper Business Certificate Application, while many applicants can start through the online business license application. Home-address business licenses are not accepted online. Do not assume that a state LLC, seller’s permit, or county DBA is enough.
For many physical businesses, completed applications go to the Business Services Division and may be routed to Planning, Building and Safety, Public Health, Police, Fire, Environmental, or another reviewer. The city’s Customer Services page also warns that some business types, such as used car dealers, restaurants, and liquor stores, may need extra permits, documents, information, or applications.
Do not treat filing as final approval. The city’s form says preliminary filing does not prove that the business has met Fontana City Code or other regulatory requirements. Contractors should also use current CSLB licensing guidance: the city-hosted PDF still contains an older contractor minor-work dollar threshold, while current state guidance uses $1,000 and also looks at permit requirements and employee labor.
What does this mean for me?
Whether you run a shop, office, restaurant, warehouse, salon, home business, mobile service, or outside business working in Fontana, check both the city license and the rules tied to the activity and address.
Zoning, home business, building, signs, and food trucks
Zoning and location checks
Before signing a lease, confirm that the activity is allowed at the address. Fontana can route a business-license application to Planning. The city’s Applications and Fees page lists planning items and directs applicants to Build Fontana.
Ask Planning early if the use involves customers, noise, odors, outdoor work or storage, chemicals, vehicle repair, alcohol, entertainment, or food preparation.
Home-based businesses
Home-address business licenses are not accepted online. Fontana’s home occupation self-certification checklist covers employees, customer traffic, signs, storage, vehicles, equipment, nuisance impacts, and residential character. See BLG’s home occupation permit guide for background.
Home food businesses are a separate category. California cottage-food rules and San Bernardino County health registration or permitting can apply in addition to Fontana land-use review. Use the county’s EHS applications page.
Building, fire, and occupancy questions
A new use, remodel, equipment change, public occupancy, storage setup, or construction can trigger site approvals. Use Fontana’s building permit information and, when it fits the situation, the direct Certificate of Occupancy application. A landlord’s past approval may not cover your use.
Signs
Signs can need planning review. Check Fontana’s current signs checklist before ordering permanent or temporary signage, and also check property-owner requirements.
Food trucks
Fontana’s food truck information requires a Food Truck Temporary Use Permit, city business license, and San Bernardino County health approval. It also addresses locations, operating rules, site documents, and renewal. Certain lunch trucks serving employees at industrial sites or active construction zones can be exempt from the TUP but still need the city license and county health clearance.
For the wider permit stack, see BLG’s food truck license guide.
San Bernardino County steps that may apply
Fictitious business name, often called DBA
If you use a business name that is not your personal legal name, or an entity uses a name that is not the exact Secretary of State name, a county FBN filing may apply. San Bernardino County’s Fictitious Business Names page says filing generally must occur within 40 days of first transacting business; an FBN is generally effective for 5 years; and publication must run once a week for four consecutive weeks, beginning within 45 days.
Effective July 1, 2026, the county lists a $90 FBN filing fee and $2 for each additional FBN or registrant name. Publication cost is separate.
Health permits and food businesses
San Bernardino County Environmental Health Services handles several distinct food paths. Its applications page and food facilities page route permanent facilities, mobile food, temporary food events, cottage food, and other food activities to the correct forms.
County land-use permits
If the address is outside Fontana, county local rules may apply instead. Start with San Bernardino County EZ Online Permitting for county planning, building, fire, public works, and related permits.
California state registrations and licenses
State filings and city licenses do different jobs. Match the state step to the business activity.
| State step | When to check it | Official start point |
|---|---|---|
| Entity filing | LLC, corporation, limited partnership, or similar entity. Online filers now need bizfile User Access. | bizfile California |
| Seller’s permit / CDTFA account | Many sellers or lessors of taxable tangible goods, plus activities needing another CDTFA account. | CDTFA registration |
| Employer duties | Commercial employers generally register within 15 days after paying more than $100 in wages in a quarter and report new or rehired California employees within 20 days of starting work. | EDD registration and required filings |
| Professional or trade license | Regulated work such as salons, health care, auto repair, security, real estate, child care, or accounting. | CalGOLD and the regulating agency |
| Contractor license | CSLB generally requires a license when a project needs a building permit, uses employee labor, or reaches $1,000 or more in combined labor and materials. | CSLB guidance |
| Alcohol license | Alcohol sales can require California ABC licensing plus local approvals. | ABC licensing |
Future fee watch: ABC says application and annual license fees will rise 3.31% over 2026 amounts on January 1, 2027. Use its license fee page when budgeting.
See BLG’s California business license guide and seller’s permit vs business license for background.
Federal steps to check
Most small businesses should decide whether they need an EIN. Use the official IRS EIN page, not a paid lookalike site, unless you knowingly choose a paid professional.
Some activities also need federal permits. The SBA’s licenses and permits page explains the federal layer for regulated activities.
FinCEN finalized its current BOI framework on August 11, 2026. The practical domestic-company exemption already applied before this review period: U.S.-created entities and U.S. persons are exempt, while certain foreign entities registered to do business in the United States may still have reporting duties. Use FinCEN’s BOI reporting page rather than older BOI instructions.
Costs you can plan for
Fees vary by activity and review. Use current government fee pages and invoices, not a third-party estimate.
| Cost item | Current official information | Before paying |
|---|---|---|
| Fontana application | $35 initial application fee for the majority of business types. | Extra review, tax, or activity-specific charges may apply. |
| Fontana renewal | $15 annual renewal fee for the majority of business types. | Use the current renewal notice or portal. |
| Annual business tax | Based on estimated annual gross receipts, with exceptions. | Use the city rate schedule and invoice. |
| State CASp fee | The city’s business certificate form shows $4. | Confirm the current total on the city invoice. |
| County FBN | Since July 1, 2026: $90 filing, plus $2 for each additional FBN or registrant name. | Publication cost is separate. |
| Seller’s permit | CDTFA online registration is generally free, though some programs can involve a fee or deposit. | Use official CDTFA registration. |
| Other permits | Building, health, sign, food-truck, alcohol, and trade fees depend on the exact activity. | Check the current agency fee schedule. |
Real-world examples
Example 1: Home-based online seller
A Fontana resident sells handmade items online from home. The owner should not rely only on an Etsy, Shopify, or payment account. They should contact Fontana about a home-based business license because the city says home-address licenses are not accepted online. They should check the home occupation checklist, check whether they need a California seller’s permit, and consider an FBN if the shop uses a trade name.
Example 2: Restaurant or food shop
A small restaurant may need a city license, zoning approval, building review, fire or hood review, county health plan review and permit, seller’s permit, and possibly alcohol licensing. The city license is only one part of the stack.
Example 3: Contractor working on Fontana jobs
A contractor based outside Fontana but taking jobs in the city should first verify whether the job site is inside Fontana or in an unincorporated county area. Then check the Fontana business-license rule, local permit needs, and current CSLB licensing rules. Do not rely on the older contractor threshold printed inside the city-hosted paper business-license form.
Example 4: Food truck
A food truck should check the city TUP, city license, county health permit, site plan, property owner affidavit, vehicle registration, and location limits. A county health permit alone is not enough.
Phone and email scripts
Use these short scripts when you contact the city, county, or state. Replace the bracketed words with your facts. Keep notes of the name of the person you spoke with and the date.
City business license script
Hello, I plan to operate a [business type] in Fontana at [address]. Do I need a City of Fontana Business License / Tax Certificate, and should I apply online or use a paper process?
Planning and zoning script
Hello, I want to use [address] for [business activity]. Is this use allowed, and do I need zoning clearance, home occupation approval, a TUP, sign review, or another planning approval?
County health or food script
Hello, I plan to [prepare, store, sell, serve, or distribute food] in Fontana. Which county health application, plan check, permit, or inspection should I complete before opening?
State seller’s permit script
Hello, my Fontana business will sell [products] to [customers]. Do I need a CDTFA seller’s permit or another CDTFA account before I begin selling?
Do not ask an agency to give legal advice. Ask which application, permit, tax account, inspection, or next office applies to your facts.
Common mistakes to avoid
- Thinking a California LLC means you have permission to operate in Fontana.
- Using a trade name without checking San Bernardino County FBN rules.
- Signing a lease before asking Planning whether the use is allowed.
- Starting a home business without checking Fontana’s home occupation limits.
- Ordering signs before checking sign permit and landlord rules.
- Opening a food business before county health plan review or inspection is done.
- Assuming a seller’s permit is the same as a city business license.
- Ignoring business license rules because the business is mobile or based outside Fontana.
- Forgetting to renew the city license, FBN, health permit, state license, or employer account.
- Paying a third-party website for a basic EIN or state registration without checking the official agency first.
What to do if this doesn’t work
If the online portal will not accept your address, if your suite number is not recognized, or if your business is home-based, stop and contact the city instead of forcing the application. The Fontana online application page tells users to download and complete a commercial zoning review form when a valid USPS address has a unit or suite number that is not recognized.
If the city says the site is not in Fontana, ask whether the property is in an unincorporated county area or another city. For county areas, start with San Bernardino County EZOP and the county office that handles the activity.
If one department says no, ask what condition, change, different location, permit, or appeal path may be available. Do not build, open, buy signs, or order food equipment until you understand the issue.
A compact compliance checklist
- Confirm the business address is inside the City of Fontana.
- Check the city business license / tax certificate process.
- Ask Planning whether the use is allowed at the address.
- Check whether a Certificate of Occupancy, building, fire, sign, or other site approval is needed before opening.
- Check whether home occupation, TUP, sign, building, fire, or health review applies.
- File a San Bernardino County FBN if your business name requires it.
- Register with CDTFA if you need a seller’s permit or other tax account.
- If you hire, register with EDD when the employer threshold is met and report new or rehired employees on time.
- Check state professional, contractor, food, alcohol, child care, auto, or health care licensing rules for your business type.
- Get an EIN from the IRS if your structure or tax situation needs one.
- Save copies and set renewal reminders.
