Testing Labs

A cannabis testing lab is an independent company that tests cannabis and cannabis products for contaminants such as mold and pesticides, and tests for concentrations of compounds such THC and CBD prior to sale at a dispensary (retail operation). 

Cannabis Land Use Permit

Cannabis testing labs require a minor use permit from Permit Sonoma to operate in the industrial zones (MP, M1, M2, and M3) and a conditional use permit to operate in certain commercial zones (C3 and LC).

Permit Sonoma reviews use (discretionary) permits. Each application is reviewed and conditioned on a case-by-case basis. Each permit is subject to public notification and environmental review. A minor use permit may be approved administratively without a public hearing if one is not requested by the public.
