Full Breakdown
City Code § 22-204(a) fixes maximum sound levels (L10 and L90, in dBa) for stationary sources by receiving land-use district and time of day, measured 5 feet above the property boundary. Residential districts are capped at 65/55 dBa from 7:00 a.m. to 10:00 p.m., dropping to 60/50 dBa overnight (60/50 dBa also applies 7, 9 a.m. Sundays). Commercial/agricultural districts run 72/62 dBa by day and 67/57 dBa overnight. Industrial districts are capped at 85/75 dBa at all hours. Under § 22-204(b), exceeding these limits by another 20 decibels at any single moment is an additional violation, and where a source spans two zones, the stricter zone's number applies at the boundary.
Violations & Fines
Any measured exceedance is a violation of Ch. 22, Art. V, enforced by the planning and environmental services department; variances are available only through the director under § 22-208.
