Cannabis Permits and Inspections

Zoning Permits for Outdoor Cannabis Cultivation

The Sonoma County Department of Agriculture / Weights & Measures issues Zoning Permits for Outdoor Cannabis Cultivation in Agriculturally zoned areas (Land Intensive Agriculture, Land Extensive Agriculture, and Diverse Agriculture) of the unincorporated county. The department will be issuing:

  • Outdoor cottage permits in the Land Intensive Agriculture (LIA) zone and
  • Outdoor cultivation permits of 10,000 sq. ft. or less in the Land Extensive Agriculture (LEA) and Diverse Agriculture (DA) zones. 
  • All other outdoor cultivation permits require a use permit and must be obtained through the Permit and Resource Management Department (Permit Sonoma). 

A complete Cannabis Cultivation Zoning Permit Application is required for all zoning permits issued by the Department of Agriculture/Weights & Measures. 

A complete Cannabis Cultivation Renewal Application is required prior to the expiration date of the current permit.  Applications for permit renewal may be administratively approved by the agency having jurisdiction provided there are no outstanding violations related to health, safety, land use, or tax. 

Best Management Practices Compliance

In addition, we will be conducting in-season monitoring inspections of outdoor, indoor, and mixed light cultivation, and nursery operations to verify compliance with the Cannabis Cultivation Best Management Practices.

Loss Determination Inspections

The department will also be performing loss determination and verification inspections for outdoor, indoor, and mixed light cultivators who experience loss due to the presence of visible surface pests and disease or weather-related loss that is visibly apparent. The loss determination and verification are fee-based inspections for tax relief associated with un-marketable product.

Scales and Scanner Inspections

The Division of Weights and Measures will be inspecting and sealing all scales used by cultivators and dispensaries across which a sale is made. Scanner systems at point of sale must be accurate and labeling of packaged products must be compliant with State and Federal regulations.
