Under Ordinance 17-011, adopted December 12, 2017, Orange County prohibits all outdoor personal cannabis cultivation within unincorporated areas.

Plants must be grown in a fully enclosed and secured area not visible from the exterior of the residence. The cultivation area must comply with all building, electrical, and fire codes. The ordinance also prohibits all commercial cannabis cultivation, manufacturing, testing, distribution, and retail operations in unincorporated Orange County. A 2026 zoning code amendment (CA 25-02) reaffirmed the outdoor cultivation prohibition and commercial cannabis ban.
