Home Cultivation
Longmont allows personal-use marijuana home cultivation in line with Colorado state law. Under LMC § 9.60.060, no more than 30 marijuana plants may be cultivated in any single dwelling unit, including a dwelling unit in which up to five unrelated individuals reside. State law (Colorado Constitution Article XVIII, Section 16 and C.R.S. 18-18-406) caps each adult 21+ at six plants, and the household total at twelve plants for two or more adults — Longmont's 30-plant per-unit ceiling functions as the upper bound where multiple medical patients or unrelated adults share a residence.
