Full Breakdown

Under Proposition 64 (Adult Use of Marijuana Act, 2016), California adults 21+ may cultivate up to 6 cannabis plants per residence for personal use. Tuolumne County has adopted Ordinance Code §17.67.065 prohibiting all commercial cannabis activities requiring a state license, including cultivation, processing, manufacturing, distribution, testing, and retail sale. However, state law prevents the county from banning personal home cultivation of up to 6 plants. Plants must be grown in a locked, enclosed area not visible from public places. The county's rural character and large lot sizes mean most home cultivation occurs without issue, but it must remain non-commercial.

Violations & Fines

Exceeding 6 plants: criminal violation. Commercial cultivation: county ordinance §17.67.065 violation. Growing visible from public: state law violation.
