Colorado Amendment 64 and state law allow adults 21 and older to cultivate up to six marijuana plants per person at home, with a maximum of twelve plants per household regardless of the number of residents. Denver's DRMC Chapter 6, Article V regulates marijuana-related activities within city limits, including home cultivation requirements.
Plants must be grown in an enclosed, locked space not visible from public areas. The growing area must not be accessible to persons under 21. Colorado law caps home grow at 6 plants per adult (3 mature, 3 immature) with a household maximum of 12 plants regardless of the number of adults. Denver does not require a permit for personal home cultivation within state limits. Landlords may prohibit growing in rental properties. Cultivation using volatile solvents (butane extraction) is illegal. Home grows may not exceed the state plant count even with a medical card unless registered with the state.
Exceeding plant limits can result in criminal charges ranging from a petty offense (up to 15 plants) to a felony (30+ plants) under Colorado Revised Statutes §18-18-406. Growing in an area accessible to minors or visible to the public may result in code enforcement action. Using butane or other volatile solvents for extraction is a felony.
