Summary
Longmont bans marijuana cultivation, product manufacturing, and testing facilities citywide, carving out one narrow exception: state- and city-licensed marijuana stores operating under Chapter 6.70's capped licensing program.
It is unlawful ... to operate ... a marijuana cultivation facility, a marijuana product manufacturing facility, a marijuana testing facility, or a retail marijuana store, and all such uses are hereby prohibited in any location within the city... As an exception to the prohibitions provided in sections 9.60.040 and 9.60.045, it shall not be unlawful ... to operate ... a marijuana store licensed by the city under the provisions of chapter 6.70, but only to the extent that such operations are in full compliance with such chapter.
Full Breakdown
Longmont Municipal Code § 9.60.045 makes it unlawful to operate a marijuana cultivation facility, marijuana product manufacturing facility, marijuana testing facility, or retail marijuana store anywhere in the city, including areas later annexed. Section 9.60.047 then carves a single exception: a marijuana store licensed by the city under Chapter 6.70 may operate, but only while it stays in full compliance with that chapter and its license conditions. The practical result is a partial opt-out. Longmont has banned marijuana cultivation, manufacturing, and testing operations outright while allowing a capped number of licensed retail marijuana stores under the separate Chapter 6.70 licensing system.
Violations & Fines
Operating a prohibited marijuana cultivation, manufacturing, or testing facility violates § 9.60.045 and is punishable by up to $500 and 90 days in jail under § 9.60.070; each day of operation is a separate offense.
