How do I determine what planning authority to go through for my business?
Sonoma County is generally split between unincorporated communities and incorporated cities.
Permit Sonoma has a handy tool to help you determine which zoning and permitting authorities oversee your business! Simply enter your address, then click "View Report," and scroll down to see the Parcel Details.
Navigating the permitting and zoning authorities can be confusing! Generally, Sonoma County can be split by incorporated and unincorporated communities. Unincorporated communities are overseen by the County of Sonoma, while incorporated cities set their own policies and procedures.

If you live in an unincorporated area, you will typically interact with Permit Sonoma. Some unincorporated communities may also have a Municipal Advisory Council (MAC) that assists the County with public administration, including permitting.
