Personal Cultivation

On June 6, 2017, the Board of Supervisors adopted an ordinance amending the County Zoning Code to place reasonable regulations on the home cultivation of cannabis plants by adults for personal use. In the unincorporated areas, no special permit is required for personal cultivation. However, adults who grow cannabis for personal use are responsible for knowing and obeying all applicable regulations. These include:

  • Plants are limited to six per dwelling unit/residence
  • Cultivation areas must be secured
  • Plants cannot be visible from any public right-of-way

Outdoor personal-use cultivation is subject to additional regulations:

  • Outdoor cultivation is only permitted at single-family residences
  • No outdoor cultivation is permitted within 600 feet of a library, park, school, daycare center or youth center
  • Outdoor cultivation is not permitted within a front yard, or within 10 feet of any property line
  • Cultivation areas must be surrounded by an opaque fence or wall at least six feet high and plants may not exceed six feet in height

Adults who cultivate cannabis indoors are also advised to familiarize themselves with best practices to minimize the risks of mold, fire and other hazards. Rules for medical and nonmedical personal cultivation are the same under the County’s ordinance. For more information, please refer to the Department of Regional Planning’s information.
