Initiative 502 legalized adult cannabis retail in Washington but did not authorize home cultivation. King County residents may not grow recreational cannabis at home. Only state-licensed Liquor and Cannabis Board producers can cultivate, and qualifying medical patients have narrow limits.
Under RCW 69.50 as enacted by I-502, adult home grows of recreational cannabis remain unlawful in Washington. Only entities licensed by the Washington State Liquor and Cannabis Board may cultivate. Qualifying medical cannabis patients on the state authorization database may grow limited plants under RCW 69.51A, with cooperative grows of up to four patients permitted. King County mirrors state law in unincorporated areas; cities including Seattle follow the same statewide framework. Possession of recreational plants by adults without medical authorization remains a misdemeanor.
Unlicensed cultivation can result in misdemeanor or felony charges depending on plant count, civil forfeiture of equipment, and tax liability. Landlords may also evict tenants for lease violations.
