Manitou Springs, CO Noise Ordinances: Decibel Limits (2026)

; commercial zones are allowed 60 dB(A) by day and 55 dB(A) at night. A noise measured at or above the applicable figure is declared excessive, unusually loud and unlawful. When a noise source can be measured from more than one zone, the more restrictive zone's limit controls, so a commercial source audible in an adjacent residential area is held to the lower residential number. , the listed levels may run ten dB(A) higher for no more than fifteen minutes in any single hour, covering brief spikes like deliveries or yard equipment.

Periodic, impulsive or shrill noises are held to an even tighter standard, five dB(A) below the table limits, because that kind of sound is more disruptive than continuous noise at the same level. Readings are taken with an A-weighted sound level meter at least twenty-five feet from the source, and only when wind is under five miles per hour, or twenty-five with a windscreen; a violation can still be proven without a meter under the same reasonableness factors used elsewhere in the chapter. 010(E)(13) and can be enforced in Municipal Court or abated by the city.
