Grand Junction, CO Cannabis Regulations: Dispensary Zoning (2026)

Chapter 5.13 GJMC, the City of Grand Junction Regulated Cannabis Code, recites that voters approved ballot measures in April 2021 authorizing marijuana business taxation and that, 'consistent with its lawful authority, this chapter affirmatively authorizes licensing and regulating cannabis related businesses in the City of Grand Junction,' rather than exercising the municipality's option under the Colorado Marijuana Code to prohibit them, so Grand Junction is opted in, not opted out. Zoning-specific siting rules sit separately in the Use Standards chapter. GJMC § 21.04.030(d)(8)(ii) applies three location restrictions to every regulated cannabis store: it is unlawful to operate one in a building that contains a dwelling unit, occupied or not; no more than two regulated cannabis stores may operate within the Horizon Drive Business Improvement District boundaries; and no regulated cannabis store may occupy the ground floor of any building in the downtown area defined as Main Street between the west line of First Street and the centerline of Seventh Street.

These zoning standards apply on top of, not instead of, the licensing requirements in GJMC Chapters 5.13 and 5.14, so a location that clears the zoning test still needs a separate City cannabis business license before opening. Community Development reviews zoning compliance at site plan and building permit stage, while the City's cannabis licensing authority created under § 5.13.015 separately reviews and can suspend or revoke the operating license for noncompliance with either the zoning rule or the licensing chapter.
