Oregon Measure 91 allows adults 21+ to grow up to 4 cannabis plants per household in Washington County. Plants must be out of public view. Unincorporated county and most cities (Beaverton, Hillsboro, Tigard) permit home grows consistent with state law.
Oregon Ballot Measure 91 (2014) and ORS 475B.245 allow persons 21 and older to cultivate up to 4 cannabis plants per household (not per person) for personal use. This right applies statewide and Washington County does not impose stricter limits. Plants must be concealed from public view — visible grows from streets, sidewalks, or neighboring properties violate ORS 475B.245(1)(c). Home grows must be in locked, enclosed space if there are minors in the household or if it is a multi-family dwelling. Cities within the county generally defer to state law: Beaverton, Hillsboro, Tigard, Tualatin, Sherwood, Forest Grove, Cornelius, North Plains all permit home cultivation without additional permits. Possession limits also apply: up to 8 oz usable marijuana at home, 10 seeds, 4 immature plants. Landlords may prohibit cannabis cultivation and smoking in rental agreements — this trumps state personal-use rights. Odor that crosses property lines can be a nuisance under ORS 30.930 common-law framework. Growing for sale requires OLCC licensing; unlicensed sales are criminal under ORS 475B.301. Medical cardholders registered under Oregon Medical Marijuana Program can grow additional plants at a designated grow site.
Over 4 plants: Class B violation $250-$1,000 first offense. Commercial-scale unlicensed grow: Class A misdemeanor or felony depending on amount. Visible grow: warning plus correction order.
