Full Breakdown
Proposition 64 (Adult Use of Marijuana Act, 2016) legalized personal cannabis possession and cultivation statewide, allowing up to 6 plants per residence for adults 21+. Cities may not prohibit indoor personal cultivation but may regulate it. Folsom Municipal Code §17.102 (Cannabis Regulations) bans all outdoor cannabis cultivation; plants must be grown inside a fully enclosed, secure residential structure or accessory structure with a locking door. The grow space must be equipped with proper ventilation/odor control (carbon filters) so odor is not detectable at the property line, and lighting must comply with the California Electrical Code. Plants must not be visible from public right-of-way. Rental tenants need written landlord consent. Using butane honey oil or other volatile solvents to process cannabis at home is prohibited under Health & Safety Code §11379.6 and FMC cannabis regulations. Medical patients remain subject to the same 6-plant household limit unless a doctor's recommendation authorizes more under MAUCRSA.
Violations & Fines
Outdoor cultivation or exceeding 6 plants: administrative citation $500-$1,000 first offense; misdemeanor possible. Volatile manufacturing: felony under H&S Code §11379.6 (up to 7 years prison).
