Illinois law permits home cannabis cultivation only by registered medical patients, capped at five plants per household, and preempts local bans or expansions of recreational home grow.
Under the Cannabis Regulation and Tax Act (410 ILCS 705/), recreational adult-use cultivation at home is prohibited. Only registered medical cannabis patients aged 21 or older may cultivate up to five plants in an enclosed, locked space at their primary residence per 410 ILCS 705/10-5. Plants must not be visible from public view. Municipalities cannot authorize recreational home cultivation, nor can they ban medical patient cultivation, since the state law sets the exclusive framework statewide.
Recreational adult-use home cultivation, growing more than five plants, cultivating without medical patient registration, or visible outdoor cannabis plants.
