Full Breakdown
Under Section 17.58.050(B), any noise generated by a use or activity is capped based on the zoning of the property that receives it. Single-family and limited multi-family areas may not exceed 50 dBA Ldn/CNEL from 10 p.m. to 7 a.m., rising to 60 dBA during the day. Multi-family, public-institution and neighborhood-commercial areas are capped at 55 dBA at night and 60 by day. Medium and heavy commercial areas allow 60 dBA at night and 65 by day. Corrections in Table 17.58.050-2 adjust readings up to 15 dB for intermittent sources or down 5 dB for impulsive or fluctuating noise.
Violations & Fines
A reading above the Table 17.58.050-1 limit for the receiving zone and time of day is a Chapter 17.58 violation; it defaults to an infraction under § 1.16.010, with fines escalating from $100 to $500 for repeats within a year.
