Does Sonoma County issue or require business licenses?
No business license is required to conduct a business in the unincorporated areas of the County. You will need a home occupation Zoning Permit to operate a small-scale business from your home. If you would like to establish a new business or to occupy a vacant business location in a commercial or industrial zone, you will need to obtain Design Review approval. In some cases, a Use Permit may also be required. Fictitious business names can be obtained from the Sonoma County Clerk.
