Summary
West Valley City limits fixed equipment like HVAC and AC condensers to zone-based sound levels: 50-55 dB(A) in residential zones, 55-60 dB(A) in commercial, and 75-80 dB(A) in manufacturing zones.
It shall be a violation of these rules and regulations for any person to operate or permit the operation of any stationary source of sound creating a ninetieth percentile sound pressure level (L90) for any measurement period... that exceeds the limits set forth for the following zones when measured at the boundary or at any point within the property affected by the noise: Residential/Agricultural: 50 dB(A) (10 p.m.-7 a.m.), 55 dB(A) (7 a.m.-10 p.m.). Commercial: 55 dB(A) / 60 dB(A). Manufacturing: 75 dB(A) / 80 dB(A).

Full Breakdown
Municipal Code § 24-22-109 sets the stationary-source noise ceiling that governs fixed equipment such as HVAC condensers and rooftop units. Measured at the property boundary, the 90th-percentile sound level may not exceed 50 dB(A) (10 p.m.-7 a.m.) or 55 dB(A) (7 a.m.-10 p.m.) in Residential/Agricultural zones, 55/60 dB(A) in Commercial zones, and 75/80 dB(A) in Manufacturing zones. Where a source is heard across two land-use categories, the more restrictive zone's limit applies at the boundary, and pure-tone or cyclical sounds, common in compressor units, get a further 5 dB(A) reduction.
Violations & Fines
A stationary HVAC or similar fixed unit exceeding its zone's dB(A) ceiling at the property boundary violates § 24-22-109 and is enforced as a class B misdemeanor.
