All commercial cannabis activity — including retail dispensaries, cultivation, manufacturing, testing, and distribution — is banned in unincorporated LA County (including Altadena) under Ordinance 2017-0025.
LA County Ordinance 2017-0025 (adopted June 6, 2017) bans all commercial cannabis uses and activities in the unincorporated areas, extending the original 2010 medical marijuana dispensary ban. The ban covers retail (medical and adult-use), commercial cultivation, manufacturing, testing, and distribution. The County is developing a draft Commercial Cannabis Ordinance (Title 22 amendments) that would create a regulatory framework, but as of 2026 the ban remains in effect. Delivery from licensed dispensaries in other jurisdictions is permitted statewide under California Bureau of Cannabis Control rules.
Unlicensed commercial cannabis activity is a misdemeanor under Title 22 and California Business & Professions Code 26038 — fines up to $30,000 per violation per day plus closure.
