Summary
Colorado's Noise Abatement Act does not exempt construction. Under C.R.S. 25-12-103, construction noise is measured against the higher industrial-zone limits during the permitted construction period, and cities may set stricter construction hours.
(5) Construction projects shall be subject to the maximum permissible noise levels specified for industrial zones for the period within which construction is to be completed pursuant to any applicable construction permit issued by proper authority or, if no time limitation is imposed, for a reasonable period of time for completion of project.
Full Breakdown
C.R.S. 25-12-103 provides that construction projects are subject to the maximum permissible noise levels specified for industrial zones (80 dB(A) daytime, 75 dB(A) nighttime) for the period within which construction must be completed under any applicable permit, or for a reasonable completion period if none is set. There is no statutory 7 a.m. to 7 p.m. exemption; construction simply receives the industrial ceiling regardless of the zone it occurs in. Local governments retain authority to set narrower construction hours, require permits, or impose weekend and holiday restrictions.
Violations & Penalties
Construction noise exceeding the industrial-zone limits, or work outside locally permitted hours, may be enforced as a public nuisance under C.R.S. 25-12-108 and can trigger local stop-work orders or fines.
