Construction hours in Bozeman, MT — sometimes called construction noise rules or contractor work-hour ordinances — set when contractors can run power tools, hammers, and heavy equipment.
Bozeman's 2024 noise-code update - the first revision since 2001 - set a specific construction-noise standard: construction activity may not produce noise exceeding 60 decibels above the ambient level between 8:00 p.m. and 7:00 a.m. Outside that window, daytime construction is generally permitted.
As part of its first noise-code overhaul since 2001, the Bozeman City Commission adopted a construction-noise standard under Chapter 16, Article 6 of the Bozeman Municipal Code. The standard prohibits construction-related noise that exceeds 60 decibels above ambient levels during the nighttime window of 8:00 p.m. to 7:00 a.m. The change was driven by Bozeman's rapid growth and resident complaints about early-morning and late-night work on residential subdivisions and infill projects. In practice this means contractors should confine noisy construction to daytime hours (roughly 7:00 a.m. to 8:00 p.m.); nighttime work that pushes noise more than 60 dB above the surrounding ambient level is a code violation. Projects needing to work outside those hours should coordinate with the city. Emergency and public-infrastructure repair work is generally treated differently from routine construction.
Construction noise that exceeds 60 dB above ambient between 8:00 p.m. and 7:00 a.m. is enforced as a Chapter 16 noise violation - a municipal misdemeanor with a fine of up to $500 and/or up to six months in jail. The city can also pursue stop-work remedies on permitted projects that repeatedly violate the noise standard.
