Sonoma County
No local coastal development ordinance — the City of Sonoma is inland in the Sonoma Valley and lies entirely outside the California Coastal Zone, so the Coastal Act does not apply.

Santa Rosa FAQ
Does the Coastal Act override local zoning?
Yes. In the coastal zone, Coastal Act policies take precedence and the Coastal Commission can override local approvals on appeal. Local Coastal Programs must be certified by the Commission to delegate primary permit authority.
What activities need a Coastal Development Permit?
Public Resources Code 30106 broadly defines development to include construction, grading, vegetation removal, subdivision, and changes in water access or land use. Most coastal zone activity requires a CDP.
Sonoma FAQ
Do I need a Coastal Development Permit to build in the City of Sonoma?
No. The City of Sonoma is inland and not within the California Coastal Zone defined by Pub. Resources Code §30103. Building permits are issued by the City of Sonoma under Municipal Code Title 14; no Coastal Commission approval is required.
What about a property in unincorporated coastal Sonoma County?
Unincorporated coastal properties within the Coastal Zone (generally west of Hwy 1 and along the Russian River) are regulated under the Sonoma County Local Coastal Plan adopted February 4, 2025. Permits are issued by Permit Sonoma, not the City of Sonoma.
