Coastal Permit Categorical Exclusions

Community Development Agency

Most development projects within the coastal zone require a Coastal Permit. However, the Coastal Commission has granted “categorical exclusions” to the County of Marin allowing certain categories of development to not require a Coastal Permit. Qualifying categories are within select geographical areas and subject to specific criteria, which are further described in the panels below. If your project is eligible for an exclusion from CP requirements, you will need to obtain a Coastal Permit Exclusion from the County prior to issuance of building, septic, or well permits.

Current Coastal Categorical Exclusion Projects

 

Categorical Exclusion Orders, Maps and Application

A Coastal Permit Exclusion must be approved before the issuance of a building permit. The Coastal Permit Exclusion application along with the Coastal Permit Exclusion application fee can be submitted to the Planning Division at the same time a Building Permit application is submitted.
