The following is a list of work that may be performed without a building permit. If your project does not appear on this list of exempt work, you should assume that a building permit is required.
Although some work is exempt from a building permit, additional permits or review may be required. Before a building or structure is erected, constructed, enlarged, altered, repaired, moved, improved, removed, converted or demolished, it is important to contact the appropriate staff at Permit Sonoma to determine if any other permit or technical review is required.
Although work may be exempt from a building permit, it may be subject to other county regulations ( Well & Septic, Use or Zoning, Drainage, Sewer, etc.). Although a building permit is not required, the exempt construction/work must be code compliant. For example, re-striping a commercial parking lot is exempt from a building permit, however, the striping must conform to building code standards for accessibility and Zoning standards for parking lot design. Failure to comply with code requirements may constitute a violation.
