Adults 21 and older may grow up to six cannabis plants per private residence in San Bernardino County, but unincorporated areas require indoor cultivation inside a fully enclosed secure structure.
Proposition 64 and Health and Safety Code 11362.2 allow personal cultivation of up to six plants per residence. San Bernardino County Code Chapter 84.34 restricts cultivation in unincorporated areas to a fully enclosed and locked accessory structure or interior room. Outdoor cultivation visible from public areas, neighboring parcels, or aerial view is prohibited. Renters need written landlord permission. Plants must not be visible from the public right of way and must use secure ventilation that prevents odor migration to adjacent parcels in desert and mountain communities.
Outdoor or unenclosed cultivation, more than six plants, or commercial sales without a state license trigger nuisance abatement and fines up to 1000 dollars per plant per day.
