The county building department in Sonoma County administers construction permits and enforces building codes for unincorporated areas and municipalities that contract county services rather than maintaining their own building divisions.

Property owners in unincorporated Sonoma County should verify with the county building department whether their parcel falls under county or municipal jurisdiction before submitting permit applications, as this affects which office handles the review and which codes apply.
