Adults 21 and over in Santa Ana may cultivate up to six cannabis plants per private residence under California Proposition 64, but Santa Ana requires indoor cultivation only.
California Proposition 64, codified in Health and Safety Code section 11362.2, lets adults 21 and over grow up to six plants for personal use at their primary private residence. Santa Ana implements this through Title 18.51 by requiring all personal cultivation to take place inside a fully enclosed, secured structure that is not visible from public view. Outdoor backyard grows are prohibited even if compliant with the six-plant cap. Plants must be kept away from children and reasonable security must prevent diversion. The six-plant cap is per residence, not per resident.
Outdoor cultivation of any cannabis, exceeding the six-plant limit per home, or growing in an unsecured area accessible to minors.
