Business Assistance Guide – Location, Location, Location

Where you decide to locate your business is one of the most important decisions you will make. Regulations, licenses, permits, filings, zoning, and other factors will affect any Sonoma County site at which you choose to operate your business. Whether you plan a one-person office operated out of your home, a produce stand in an unincorporated area, or retail or service outlet, certain guidelines and procedures must be followed to ensure that you meet legal requirements that allow you to operate successfully.

Planning and Zoning

Sonoma County has nine incorporated cities that decide issues affecting your location within their city limits. Throughout the county’s unincorporated areas, many locations are affected by regulations that govern land use and development, protection of the environment and factors such as water quality. Local, regional and state boards and regulatory agencies can all impact the type of business you plan to operate in a particular location.

Choosing a Location

  • Association of Bay Area Governments: The Association of Bay Area Governments includes links to Sonoma County city governments of Cloverdale, Cotati, Healdsburg, Petaluma, Rohnert Park, Santa Rosa, Sebastopol, Sonoma, and Windsor for business licenses and permit information.

Home-Based Businesses

Usually require a license from the local government agency where your business is based. Contact the municipality/city hall nearest you. If you live in an unincorporated area, contact the County of Sonoma.

Single Projects, Multiple Jurisdictions

Some seemingly simple projects may require a variety of local, state or federal permits and approvals. Sonoma County is divided between agency jurisdictions in the areas of air and water quality regulations that may overlap with Bay Area agencies. You may have to apply to multiple agencies that regulate land use and development in order to operate your business.

Some businesses require a combination of local, regional, state, and federal permits and approval. Make sure to check for overlapping regulations.
