Pasco, WA Noise Ordinances: Construction Hours (2026)

Construction noise in Pasco is governed by PMC Chapter 9.130. Under PMC 9.130.030, sounds made in connection with the construction, excavation, repair, demolition, destruction or alteration of any building or property are prohibited as a public disturbance noise when made between 10:00 p.m. and 7:00 a.m. and received within a residential district. The same section separately prohibits operating mechanically powered tools such as saws, drills, sanders, grinders, lawn or garden tools, air conditioners, fans or blowers between 10:00 p.m. and 7:00 a.m. in a way that causes a noise disturbance across a residential boundary. The City of Pasco's Common Code Violations page lists 'Construction noise between 10:00 pm and 7:00 am' as a nuisance violation, and directs residents to use the AskPasco service to report construction-noise violations occurring during those hours. In effect, construction work that generates significant noise should be confined to the daytime/evening window of 7:00 a.m. to 10:00 p.m. in or near residential areas. Daytime construction sound levels are still subject to the maximum permissible noise levels in PMC 9.130.040, which adopts the Washington State standards (WAC 173-60), though temporary construction sites receive certain state exemptions during daytime hours. These construction-hour limits are part of Pasco's own municipal code.
