Summary
Layton's Light Commercial Flex Manufacturing zoning standard, Section 19.06.270, caps machine and equipment noise at 85 decibels at the property line, with no detectable vibration, dust, odor, fumes or gas escaping the lot. Interior noise can exceed 85 dB only if sound-attenuating construction keeps it from reaching neighboring commercial or residential units.
When operated, machines and instruments shall not emit a noise level greater than 85 decibels (dB), and shall not emit detectable vibration, dust, odor, fumes or gas beyond the boundary of the property or noise above ambient level (size limit). Interior noise levels associated with business operations and machines may be increased above 85 dB if interior building sound attenuation is applied to mitigate any sound increase that would otherwise transmit into attached commercial or residential units.
Full Breakdown
" The 85 dB cap is measured at the property boundary, not inside the building, and the code gives operators an out: interior noise levels tied to business operations and machinery may run louder than 85 dB if the building's interior sound attenuation is engineered to keep that increase from transmitting into attached commercial or residential units. without detectable vibration, dust, odor, fumes or gas that extend beyond the boundary of the property," meaning heavier industrial uses can exceed the flex-manufacturing ceiling as long as nothing else escapes the lot.
m. plus weekends when the use sits directly against a residential wall or ceiling. Both flex-manufacturing sections were enacted by Ordinance No. 20-38 on November 19, 2020, and the MU-TOD standard was carried forward through Ordinance No. 24-03 in January 2024.
Violations & Fines
Exceeding the 85 dB property-line limit under Section 19.06.270 or 19.26.060(4) is a Title 19 zoning violation. The Zoning Administrator enforces it under Section 19.19.020, and Section 19.19.050 treats each day the excess noise continues as a separate offense, defaulting to an infraction fine of up to $750 under Sections 1.20.050 and 1.20.090 absent a specific misdemeanor classification.
