The County considers a Greenhouse to be a principal structure related to agriculture.

To determine the type of planning permit required for a proposed greenhouse, you must determine if your project site is located in a coastal or non-coastal area.

For project sites located in non-coastal areas, greenhouses that conform to sections 8105-4, 8106-1.1, 8106-6.4, and 8107-26.1 of the Non-Coastal Zoning Ordinance are permitted on all Agricultural, Rural, and Timberland Preserve zoned parcels. However, for project sites located in coastal areas, greenhouses are permissible on condition of conformity to Section 8174-5.21 of the Coastal Zoning Ordinance.

  • Greenhouses, which are located in the non-coastal zone and meet the requirements in the Non-Coastal Zoning Ordinance may require the issuance of a Zoning Clearance (depending upon zoning and size of the greenhouse). Please fill out a Zoning Clearance Application and bring this with a set of site plans (include one set of 8.5”x11” reductions), floor plans, and elevation drawings to the Planning Public Counter at the County Government Center. To obtain the exact fee for a Zoning Clearance for a Greenhouse at your project site, please contact a planner at the Planning Public Counter at (805) 654-2488 or via email at This email address is being protected from spambots.

  • Greenhouses, which are located in the coastal zone and meet the requirements in the Coastal Zoning Ordinance may require the issuance of a Coastal Planned Development Permit (or a modification to an existing permit) by the Planning Director (unless it is in an exempt area* and other provisions of Section 8174-5.2), following environmental review and notification to neighbors. To obtain the necessary application materials and information about the approval process and fees for Coastal greenhouses, please contact a planner at the Planning Public Counter at (805) 654-2488.
