Pasco, WA Noise Ordinances: Construction Hours (2026)

PMC 9.130.030(3)(i) lists as a public disturbance noise "any sound made by the construction, excavation, repair, demolition, destruction, or alteration of any building or property or upon any building site between the hours of 10:00 p.m. and 7:00 a.m. and is received within a residential district." That is the city's operative construction-hours rule: work generating audible noise in a residential district must stop by 10:00 p.m. and cannot resume before 7:00 a.m. Outside that window, construction noise gets favorable treatment elsewhere in the chapter. PMC 9.130.050(1)(a) exempts sounds from temporary projects for maintenance or repair of homes, grounds, and appurtenances from the general environmental noise limits in PMC 9.130.040(2) between 7:00 a.m. and 10:00 p.m.

PMC 9.130.050(3)(a) goes further, exempting sounds from temporary construction sites due to construction activity from the environmental noise limits altogether, except insofar as those limits govern reception within Class A (residential) EDNAs between 10:00 p.m. and 7:00 a.m., which loops back to the same nighttime cutoff. In effect, daytime construction noise in Pasco is largely unregulated by the decibel table, while nighttime construction noise reaching a residential area is flatly prohibited regardless of decibel level. Contractors working near schools, hospitals, or nursing facilities face an additional constraint under subsection (h), which bars any audible sound in a posted quiet zone around those facilities.
