Yakima, WA Cannabis Regulations: Home Cultivation (2026)

Initiative 502 (2012), codified in Chapter 69.50 RCW, established Washington's legal recreational cannabis system administered by the Washington State Liquor and Cannabis Board (WSLCB), but did not authorize personal cultivation for recreational use. Growing cannabis without a state license — even a single plant — is a violation of RCW 69.50.401 (Manufacture, deliver, or possess with intent to manufacture or deliver a controlled substance), which classifies cannabis manufacture as a Class C felony punishable by up to five years' imprisonment and a $10,000 fine. The medical exception under Chapter 69.51A RCW, as amended by SB 5052 in 2015, allows a qualifying patient (or designated provider) entered in the Department of Health Medical Cannabis Authorization Database to grow up to six plants and possess up to eight ounces of useable cannabis from those plants for personal medical use; a healthcare practitioner may authorize up to fifteen plants under RCW 69.51A.210 in specific cases. Cooperatives of up to four registered patients may grow a combined total of up to 60 plants at one location under RCW 69.51A.250, subject to WSLCB registration, location restrictions, and a 1,000-foot buffer from schools and other sensitive uses. Yakima has not adopted any city ordinance authorizing recreational home cultivation, and could not do so without state legislative change — RCW 69.50 preempts the field. The city's Cannabis Related Land Use Information page confirms the city's regulatory authority is limited to commercial licensing and zoning, not personal cultivation. Bills introduced in Olympia in 2026 (SB 6204) to legalize limited adult home cultivation have not become law as of the city's current code through Ordinance 2026-001 (January 6, 2026).
