Temecula, CA Cannabis Regulations: Home Cultivation (2026)

California Proposition 64 (2016) legalized personal cannabis cultivation of up to 6 plants per residence for adults 21 and older. Temecula codified local rules in TMC Chapter 8.60 that prohibit all outdoor cultivation and restrict indoor growing to a single locked, enclosed space within a fully-enclosed residential structure or accessory building. The cultivation area must not be visible from any public right-of-way or neighboring property. Cannabis odors must not be detectable beyond the property line — carbon filtration is effectively required. Cultivation cannot occur in any structure used as a daycare, school, or commercial space. Renters need written landlord permission. Use of volatile solvents (butane, propane) for extraction is prohibited and constitutes a felony under state law. Electrical and ventilation modifications require building permits — unpermitted grow rooms have caused fires in Riverside County. The 6-plant limit applies per residence regardless of how many adults live there. Commercial cultivation is banned citywide. Code Enforcement responds to odor complaints and visible violations; penalties include administrative citations starting at $100 and escalating to $1,000 per day. Possession over 1 ounce or 6 plants without a state license is a misdemeanor.
