Loveland, CO Noise Ordinances: Quiet Hours (2026)

Loveland regulates noise primarily through Title 7 (Health, Safety and Welfare), Chapter 7.32 'Sound Limitations,' enacted in its current form by Ordinance 1988 (1981) and amended by Ord. 4998 (2005). LMC 7.32.010(A) makes it unlawful to make or cause any noise whose sound level, measured at 25 feet or more from any property line, exceeds the limits in 7.32.040. LMC 7.32.010(B) tightens that cap by 5 db(A) for 'periodic, impulsive or shrill noises' (so a periodic noise must stay 5 db(A) below the table). LMC 7.32.010(C) independently prohibits any 'unreasonable noise' - defined in LMC 7.32.020(H) as 'any sound of such level and duration as to be or tend to be injurious to human health or welfare, or which would unreasonably interfere with the enjoyment of life or property' - and a violation of 7.32.010(C) 'may occur without exceeding these levels and without a measurement.' The 7.32.040 table is split at 7 a.m. / 9 p.m. (note: Loveland's nighttime window starts at 9 p.m., not 10 p.m., and is two hours longer than the Colorado state default in CRS 25-12-103 which uses 7 a.m. / 7 p.m.). Zone caps: residential 55 db(A) day / 50 db(A) night; commercial 60/55; industrial 75/70. Per LMC 7.32.020(D) when a noise source can be measured for more than one zone, the more restricted zone governs. LMC 7.32.060(A) allows the table to be exceeded by 10 db(A) for up to 15 minutes in any one-hour period during the 7 a.m. - 9 p.m. window. Sound is measured per LMC 7.32.050 on the A-scale of an ANSI S1.4-1983 meter, with wind velocity no more than 5 mph. Report noise to Loveland Police Dispatch non-emergency at 970-667-2151; in-progress disturbances may also be reported via 911 if safety is at risk. State law CRS 25-12-103 provides a parallel public-nuisance backstop with the same residential numbers (55/50) but a stricter daytime/nighttime split (7 a.m. / 7 p.m.) and additional 'light industrial' and 'industrial' tiers (70/65 and 80/75).
