Summary
Centennial has opted out of commercial cannabis entirely: marijuana cultivation, manufacturing, testing, retail sales, and clubs are prohibited on every parcel in the city, so there is no zoning district where a marijuana business may locate.
It is unlawful for any person to operate, cause to be operated or permit to be operated any Marijuana Cultivation Facilities, Marijuana Product Manufacturing Facilities, Marijuana Testing Facilities, Retail Marijuana Stores or Marijuana Clubs (collectively "Marijuana Establishments") within the boundaries of the City and all such uses are prohibited on all property within the City.

City Code § 6-5-110 makes it unlawful to operate, or allow the operation of, any marijuana cultivation facility, marijuana product manufacturing facility, marijuana testing facility, retail marijuana store, or marijuana club anywhere within Centennial: the ban applies citywide with no exception by zone district. Medical marijuana centers, optional-premises cultivation, and infused-product manufacturing operations are separately banned citywide under § 6-6-110. The only lawful marijuana activity in Centennial is personal cultivation inside a primary residence, capped at six plants (three flowering) under § 6-5-220.
Violations & Fines
Operating any marijuana cultivation, manufacturing, testing, retail, or club use anywhere in Centennial violates § 6-5-110 and is enforceable as a municipal offense and public nuisance under § 6-5-530.
