Fort Collins § 20-23 sets day/night dB(A) caps by zone: 55/50 residential, 60/55 commercial, 70/65 employment, 80/75 industrial. Unincorporated Larimer County and Colorado's statute (C.R.S. § 25-12-103) use the same residential-to-industrial tiers.
Fort Collins Municipal Code § 20-23 establishes maximum permissible noise levels measured at the property line: residential/mixed-use zones 55 dB(A) (7 a.m.–8 p.m.) and 50 dB(A) (8 p.m.–7 a.m.); commercial 60/55; employment 70/65; industrial 80/75. The most restrictive district controls when a source spans zones, and pure tones drop the cap 5 dB(A). Larimer County Ordinance 97-03 and Colorado Revised Statutes § 25-12-103 apply the same tiers (residential 55/50, commercial 60/55, light industrial 70/65, industrial 80/75), with a 10 db(A) allowance for up to 15 minutes per hour during the day.
