Full Breakdown
2 give every adult 21 and older the right to cultivate up to six living cannabis plants inside their private residence, and cities may impose reasonable indoor regulations but cannot prohibit indoor personal cultivation. San Bernardino implements this through its Development Code and Municipal Code provisions on commercial cannabis, allowing indoor personal cultivation while banning all outdoor personal grows. Indoor grows must be in a secured space (locked room or closet, or a secured outdoor greenhouse that meets structural requirements), inaccessible to minors, and conducted entirely out of public view from any street, sidewalk, park, or neighboring property.
Electrical modifications including added circuits, larger lights, and ventilation require a building permit under the California Electrical Code. Ventilation must include carbon filtering or equivalent so that odors are not detectable at the property line, consistent with the city nuisance rules under Civil Code 3479. 6. 12 related tenancy provisions. Selling home-grown cannabis without a state license is illegal under Business and Professions Code Division 10.
