Quiet hours in Salt Lake County, UT — also called the noise ordinance, nighttime noise rules, or residential quiet time — define the hours during which excessive noise is prohibited.
Unincorporated Salt Lake County observes nighttime quiet hours from 10 PM to 7 AM under Title 6 of the County Code. During these hours, sounds that disturb a reasonable person at the property line are prohibited, including loud music, parties, power tools, and engine revving. Daytime noise must still stay within reasonable limits, and Unified Police Department enforces violations alongside county code enforcement staff.
Salt Lake County Code Title 6 (Offenses) regulates noise in unincorporated communities such as Magna, Kearns, Copperton, White City, and Emigration Canyon. The general nuisance noise standard makes it unlawful to create sound audible beyond the property line that disturbs the peace of neighbors, with stricter enforcement during the 10 PM to 7 AM quiet period. Residential construction, landscaping equipment, and amplified sound are typically restricted to 7 AM to 10 PM on weekdays, with some limits on early Sunday morning activity. Plainly audible standards (music or bass heard from 50 feet away) are commonly used by Unified Police Department officers rather than decibel meters, though decibel measurements may be used for commercial sources or repeat offenders. Utah Code section 76-9-102 supplements the local rule, treating unreasonable noise as disorderly conduct, a class C misdemeanor. Complaints are handled by dialing the UPD non-emergency line, and repeat violations can escalate from warnings to citations with fines. Special events and construction may apply for variances through the county. Residents in canyon communities should also be aware that sound carries considerably farther in the mountain environment, and neighbors generally expect greater quiet than in denser urban areas.
