Broomfield, CO Short-Term Rentals: Noise Rules (2026)

Section 5-39-070 lists disturbing the peace and noise as one of five mandatory limitations on every licensed short term rental, and subsection (C) requires renters to comply with chapter 9-34, Disturbing the Peace, and chapter 9-36, Noise, at all times, not merely during quiet hours. Chapter 9-36 backs that duty with a quantified standard: section 9-36-020(B) makes it unlawful to exceed the levels in Schedule 9-36A, and for the residential districts where most short term rentals sit (E-1, E-2, R-1, R-3, R-5, PUD, R-PUD), the limit is 55 dB(A) from 7:00 a.m. to 10:00 p.m. and drops to 40 dB(A) overnight from 10:00 p.m. to 7:00 a.m., measured at least twenty-five feet from the source.

Section 9-36-020(A) also bars noise that is simply of such unusual or exceptional character, intensity or duration that it disturbs the comfort, repose, health, peace or safety of a neighbor, independent of the decibel table, so a party that stays under 55 dB(A) can still violate the ordinance on that broader standard. Because section 5-39-080 makes the property owner, not just the individual guest, responsible for compliance with every chapter 5-39 limitation, a noise complaint against short term renters exposes the license itself: section 5-39-070 closes by warning that failure to comply with any listed limitation may result in a show cause hearing or revocation of the rental license, on top of whatever municipal court penalty the noise violation itself carries under chapter 9-36.
