California county licensing guide

Accuracy date: May 18, 2026. Last updated: May 18, 2026. Next review date: September 18, 2026.

This guide explains the county, city, and state license layers for starting or running a business in San Bernardino County, California. It is for general information only. It is not legal, tax, accounting, or professional advice.

The most important point is simple: do not treat “San Bernardino County” and the “City of San Bernardino” as the same licensing office. Your local license or permit path depends first on whether your business address is inside an incorporated city or in an unincorporated county area.

Bottom line: does San Bernardino County require a county business license?

San Bernardino County does not issue one general business license that covers the whole county. The county’s Clerk of the Board says businesses inside an incorporated city should contact that city for local licensing requirements, and that San Bernardino County does not issue a business license that covers the entire county.

For unincorporated county areas, the answer is more limited. San Bernardino County Land Use Services says the county requires only a limited number of business types within unincorporated areas. Its FAQ names county license categories such as massage clinic, rental dwelling unit, hotel/motel, bingo, peddler, solicitor, and taxicab service.

For many ordinary businesses, the main county checks are not a general county business license. They are more likely to be fictitious business name filing, zoning, home occupation rules, building permits, fire review, health permits, business property tax, or industry permits.

Important: If your business is inside a city such as San Bernardino, Ontario, Fontana, Victorville, Rancho Cucamonga, Redlands, Chino, Upland, Hesperia, or another incorporated city, check that city’s business license or business registration office first. City rules can control even though the mailing address says “San Bernardino County.”

First, check whether your address is in a city or unincorporated county area

Before you apply or pay any fee, confirm the jurisdiction for your exact business location. A postal address is not enough. Some addresses use a city name for mail but are actually outside city limits. Other addresses are inside a city and must follow that city’s local license rules.

San Bernardino County’s EZ Online Permitting site tells applicants to start by checking whether the parcel is in the county’s jurisdiction. The county offers an “Is My Parcel in the County?” tool and zoning resources through EZOP.

Why this matters

If the address is inside an incorporated city: the city may require a business license, business tax certificate, business registration certificate, zoning clearance, home occupation approval, sign permit, or other city permit.
If the address is in an unincorporated county area: the county may handle zoning, home occupation, building, fire, environmental health, and limited county business license categories.
Either way: the county can still matter for fictitious business names, health permits, business property assessment, and some fire or environmental programs.

Do this first: Use the county parcel or zoning tools, then confirm with the city or county office before filing. Ask, “Is this address inside city limits or unincorporated San Bernardino County?”

What San Bernardino County, CA may handle

San Bernardino County is not the same as a city business license office. County offices may still be important, but each office handles a different layer.

County layer	Office or department to check	What it may affect
Limited county business license categories in unincorporated areas	San Bernardino County Land Use Services / Code Enforcement or Clerk of the Board, depending on the business type	County Land Use Services identifies limited categories such as massage clinic, rental dwelling unit, hotel/motel, bingo, peddler, solicitor, and taxicab service. Confirm the correct office before applying.
Fictitious Business Name, often called FBN or DBA	San Bernardino County Assessor-Recorder-County Clerk	Filing a fictitious business name when the business uses a name that is not the owner’s legal name or not the exact registered entity name.
Business property assessment	San Bernardino County Assessor	Business equipment, fixtures, furniture, computers, tools, and other taxable business personal property may trigger business property statement duties.
Zoning and land use for unincorporated locations	San Bernardino County Land Use Services	Whether the business use is allowed at the property, whether planning approval is needed, and whether a home occupation permit applies.
Building permits and tenant improvements for unincorporated locations	San Bernardino County Land Use Services / Building and Safety through EZOP	New construction, tenant improvements, signs, grading, electrical, mechanical, plumbing, pools, walls, fences, and other regulated work.
Food, body art, public pools, mobile food, and other health-regulated activities	San Bernardino County Department of Public Health, Environmental Health Services	Health permits, plan review, inspections, and program-specific applications.
Fire review, inspections, and hazardous materials	San Bernardino County Fire Protection District / Office of the Fire Marshal	Fire inspections, construction fire review, hazardous materials, CUPA programs, and fire code-related requirements where applicable.

County business license wording to know

For most readers, the safe plain-English answer is: there is no single general San Bernardino County business license for every business. But a few business types in unincorporated areas may have county license requirements. Do not skip the county check just because there is no countywide license.

The official county pages should control. If the county page and your city page seem to point you in different directions, contact both offices and ask which office has jurisdiction over your address and business activity.

What cities or towns may handle

San Bernardino County has many incorporated cities. If your business is inside city limits, the city may require a local business license, business registration certificate, business tax certificate, zoning review, home occupation approval, certificate of occupancy, sign permit, sidewalk vending permit, police review, fire review, or other city-level approval.

For example, the City of San Bernardino uses the term Business Registration Certificate. Ontario uses business license wording. Fontana says businesses operating in the city must be properly licensed and also reviewed for planning, building, and public health where applicable. Victorville has a Business License Division with separate pages for in-city, home-based, out-of-city, rental property, and vendor businesses.

BLG also has a separate city guide for the City of San Bernardino: San Bernardino, CA Business License Guide.

If your business is…	Start with…	Also check…
Inside the City of San Bernardino	City Business Registration Division / Finance	County FBN, county health permits if food/body art/public pool applies, fire/building/zoning if required.
Inside Ontario, Fontana, Victorville, or another incorporated city	That city’s business license, finance, business tax, or city clerk office	City planning/zoning, city building, city fire or county fire if the city uses county fire service, county FBN, and state registrations.
In an unincorporated county area	San Bernardino County Land Use Services and EZOP	Limited county business license categories, county zoning, home occupation, building, environmental health, fire, FBN, and state registrations.
Mobile, home-based, online, or service-based	The jurisdiction where the business is based and any city where you operate in person	Some cities require out-of-city contractors, vendors, or service providers to hold a city license before doing work there.

Do not assume a county answer replaces a city answer. A business can have a county FBN, a state seller’s permit, and still need a city business license or registration certificate.

State-level registrations to check

California state registrations are separate from San Bernardino County and city rules. The state does not replace local business license, zoning, health, or FBN requirements.

California Secretary of State business entity filings

If you form a California LLC, corporation, limited partnership, or certain other entity types, check the California Secretary of State’s business entity filing system. Sole proprietors usually do not form an entity with the Secretary of State unless they choose to create one.

California seller’s permit through CDTFA

If you are engaged in business in California and sell or lease tangible personal property that would normally be subject to sales tax at retail, check whether you need a California seller’s permit from the California Department of Tax and Fee Administration. This is not the same as a city or county business license.

Employer payroll tax registration through EDD

If you hire employees, check California Employment Development Department employer registration rules. EDD says a business with one or more employees must register as an employer and set up a payroll tax account within the required time after paying more than the state threshold in wages.

Professional and contractor licenses

Some businesses need a state professional license before they can legally offer services. Contractors should check the California Contractors State License Board. Other regulated occupations may need to check the California Department of Consumer Affairs or the specific state board for that profession.

CalGOLD permit search

California’s CalGOLD permit assistance tool can help identify state, county, city, and agency contacts by location and business type. Treat it as a starting point, then verify with each official agency.

DBA, fictitious business name, assumed name, or trade name layer

In California, the common “DBA” filing is called a Fictitious Business Name, or FBN. San Bernardino County’s Assessor-Recorder-County Clerk handles FBN filings for the county.

The county says a fictitious business name should be filed within 40 days of first transacting business. Once registered, it is effective for 5 years. The county also says the FBN must be published in an adjudicated newspaper once a week for four consecutive weeks, and publication must start within 45 days of filing the statement with the County Clerk’s office.

When an FBN may be needed

A sole proprietor uses a business name that does not include the owner’s surname.
A partnership uses a business name that does not include the partners’ surnames.
An LLC, corporation, or limited partnership uses a name different from the exact legal name on record with the California Secretary of State.

What an FBN does not do

An FBN is not a city business license. It is not a seller’s permit. It is not an LLC. It does not approve zoning, food sales, signs, construction, or professional licensing. It is mainly a public name filing.

Before filing: Search the county FBN index, confirm whether the name needs to be filed, and ask the County Clerk about the current filing, publication, and renewal process.

Zoning, home occupation, building, fire, health, and industry permits

Many San Bernardino County businesses do not stop at a “business license” question. The real issue may be where the business operates, what it sells, and whether the activity is regulated.

Zoning and land use in unincorporated areas

San Bernardino County Land Use Services regulates zoning for unincorporated county areas. The county says zoning controls how land can be used, including allowed uses, intensity, density, height, placement of structures, and other land use rules. Use the county’s zoning and parcel tools before signing a lease, buying property, or starting a home-based operation.

Home occupation permits

If you run a business from home in an unincorporated area, check the county’s home occupation rules. The county explains that home occupation means using one’s home for business, but only if the home remains primarily a residence and the business does not alter the residential character of the area. The county says these rules apply only in unincorporated San Bernardino County, with regional differences for the Valley, Mountain, and Desert areas.

Building permits, tenant improvements, and signs

If you build, remodel, add equipment, change a commercial space, add signs, change electrical or plumbing, or do tenant improvements in an unincorporated area, check San Bernardino County Land Use Services and EZOP. The county lists building applications for non-residential construction, mixed use, tenant improvements, grading, electrical, mechanical, plumbing, solar, signs, demolition, pools and spas, walls and fences, and other work.

Food, mobile food, street vending, and health permits

If you sell food, operate a food facility, use a mobile food facility, vend food, run a temporary food booth, operate a wholesale food facility, or handle similar food activity, check San Bernardino County Environmental Health Services. EHS says food sellers in San Bernardino County need a health permit to legally sell food. Plan review may also apply to retail and wholesale food facilities and public swimming pools.

Body art, pools, and other environmental health programs

Body art facilities, body art practitioners, public pools, spas, water recreation, medical waste, wastewater, wholesale food, and other regulated activities may need Environmental Health Services review, permits, or registration. Do not rely on a city business license alone for health-regulated work.

Fire review, hazardous materials, and inspections

Some businesses need fire review or inspection. The San Bernardino County Fire Protection District Office of the Fire Marshal handles inspection, investigation, and regulatory functions. Its CUPA program manages hazardous materials and hazardous waste programs. Businesses with hazardous materials, certain storage, commercial construction, tenant improvements, fire protection systems, or higher-risk operations should check the fire authority for the location.

Short-term rentals and rental dwelling units

San Bernardino County has special county workflows for some rental-related activities in unincorporated areas. County EZOP materials identify a Rental Dwelling Unit License for certain long-term rental dwelling properties in unincorporated areas and a Special Use Permit process for short-term rentals. If the property is inside a city, check the city’s rental or short-term rental rules instead.

Step-by-step checklist for San Bernardino County businesses

Write down the exact business location. Use the street address, parcel number if known, and whether it is home-based, mobile, online, storefront, warehouse, office, or job-site work.
Confirm the jurisdiction. Check whether the address is inside an incorporated city or in unincorporated San Bernardino County.
If inside a city, check the city license office first. Ask for the exact local term, such as business license, business tax certificate, business registration certificate, vendor permit, home occupation approval, or zoning clearance.
If unincorporated, check San Bernardino County Land Use Services. Ask whether the use is allowed at the property and whether any county license, home occupation permit, special use permit, building permit, or code enforcement review applies.
Check FBN filing. If you use a name that may be fictitious under California law, check the San Bernardino County Assessor-Recorder-County Clerk Fictitious Business Name process.
Check California state tax registration. If you sell taxable products, check CDTFA seller’s permit rules. If you hire employees, check EDD employer registration.
Check entity filings. If forming or operating an LLC, corporation, or other registered entity, check California Secretary of State business entity filings.
Check health permits. If food, body art, pools, medical waste, wastewater, or other environmental health rules may apply, check San Bernardino County Environmental Health Services.
Check building, fire, and signs before opening. Do this before signing a lease or spending money on buildout.
Ask about renewals and changes. Confirm what happens if you move, change ownership, change your business name, add a new activity, add a food component, hire employees, or open another location.

Common mistakes in the San Bernardino County licensing stack

Confusing the county with the City of San Bernardino. A city guide is not the same as a county guide.
Assuming a mailing city means the property is inside city limits. Always verify the jurisdiction for the exact address or parcel.
Filing an FBN and thinking the business is licensed. An FBN is a name filing. It does not replace city licensing, zoning, health permits, or seller’s permits.
Skipping zoning before signing a lease. A business license application can fail or be delayed if the location is not approved for the use.
Starting a home business without checking home occupation rules. This is especially important in unincorporated county areas and residential city zones.
Selling food without checking Environmental Health Services. Food sellers, mobile vendors, temporary food booths, and some wholesale food operations may need health review or permits.
Assuming online or mobile businesses have no local layer. The home base, storage location, city where work is performed, and vending locations can all matter.
Forgetting state accounts. A city or county approval does not replace a CDTFA seller’s permit, EDD employer registration, Secretary of State filing, or state professional license.
Ignoring business property assessment. Businesses with taxable equipment, fixtures, tools, computers, or other business property may need to respond to the County Assessor.

FAQ

Does San Bernardino County issue one business license for the whole county?

No. San Bernardino County says it does not issue a business license that covers the entire county. If your business is inside an incorporated city, check that city’s business license or business registration office. If your business is in an unincorporated county area, check county Land Use Services for zoning and any limited county license category that may apply.

What if my business is in the City of San Bernardino?

Check the City of San Bernardino, not just the county. The city uses the term Business Registration Certificate. You may also need county or state items such as an FBN, seller’s permit, health permit, fire review, or state professional license depending on your business.

What if my address says Fontana, Ontario, Victorville, or another city?

Do not rely only on the mailing city. Confirm whether the address is inside that city’s limits or in an unincorporated county area. If it is inside a city, check that city’s business license or business tax office. If it is unincorporated, check San Bernardino County Land Use Services.

Is a fictitious business name the same as a business license?

No. A fictitious business name, or FBN, is a name filing through the county. It does not approve your location, tax account, seller’s permit, health permit, zoning, or city business license.

Do food businesses need a county health permit?

Many food businesses do. San Bernardino County Environmental Health Services says a health permit is needed to legally sell food in the county. Food facilities, mobile food facilities, temporary food facilities, and some wholesale food operations should check EHS before operating.

Do home-based businesses in unincorporated San Bernardino County need a home occupation permit?

They may. San Bernardino County Land Use Services has home occupation rules for unincorporated county areas. The county says the home must remain primarily a residence and the business must not alter the residential character of the area. Confirm with Land Use Services before operating from home.

Can I rely on CalGOLD instead of calling the city or county?

No. CalGOLD is a helpful starting point for permit contacts by location and business type, but you should verify the answer with the city, county, state agency, or licensing board that actually issues the permit or license.

What should I check before signing a lease?

Confirm the jurisdiction, zoning, allowed business use, parking or sign rules, building or tenant improvement permits, fire review, health permits, and city or county business license requirements. This is especially important for food, auto, manufacturing, warehouse, childcare, personal service, rental, mobile vending, and regulated businesses.
