How to Apply for a County Business License

Where is Your Business Located?

Incorporated City

If your business is located in an incorporated city limit and you conduct any business in an unincorporated area of the county, you will need to complete both the city's and the County's online Business License application (PDF).  If you conduct business only within the city's limits, you do not need to apply for a County business license.

Note: For a NAICS code number and description of your business, please refer to the North American Industry Classification System codes (PDF).

Unincorporated Area

If your business is located in an unincorporated area of the County, you will first need to contact the Department of Conservation and Development at 925-674-7200 or visit them at 30 Muir Road, Martinez, CA 94553, for zoning and planning requirements and permits. Once zoning and planning approval is secured, you may complete the online Business License application (PDF)
