Full Breakdown
Lehi City Code § 5-3-6(A) fixes the outer decibel limit for continuous and intermittent noise reaching a receiving property, sorted by that property's zoning. Residential and agricultural land is capped at 85 dBA during the day and just 55 dBA at night; commercial and light industrial land get the same 85 dBA daytime ceiling but a 65 dBA nighttime limit. Separate, lower tables in the same section (5-3-6(B) and (C)) apply tighter limits specifically to continuous noises (65 dBA day/55 dBA night in residential zones) and intermittent noises (70/60), and a fourth table in 5-3-6(D) governs impulse noises like gunshots.
A city police officer or the designated Code Enforcement Officer measures compliance with a calibrated Type 1 or Type 2 sound level meter positioned per § 5-3-5, either at the property line or 50 feet from the source, and a reading must exceed the applicable limit for at least 30 seconds to count as a violation. Where a noise source can be measured from more than one zone, the most restrictive zoning classification governs. 060 and were most recently amended by Ordinance 04-2026 on February 10, 2026.
Violations & Fines
Exceeding the applicable dBA table is a class C misdemeanor under Lehi City Code § 5-3-8, punishable per § 1-4-1, with each day of continuing violation charged as a separate offense. Responsibility can fall on the person creating the noise, the business or contractor operating the equipment, or the property owner or tenant who permits it, per § 5-3-7A.
