Pasco, WA Noise Ordinances: Quiet Hours (2026)

The City of Pasco regulates nighttime noise through Chapter 9.130 of the Pasco Municipal Code (Title 9, Peace, Safety and Morals). PMC 9.130.030 makes it unlawful to create a 'public disturbance noise,' and it specifically enumerates sounds that are prohibited when received within a residential district between 10:00 p.m. and 7:00 a.m. These include sounds from musical instruments, whistles, sound amplifiers, juke boxes, radios, televisions or similar devices emanating from a building, structure or property, as well as sounds from the unamplified human voice. The City's official website summarizes the rule plainly: 'Public noise disturbances are prohibited from 10pm - 7am in residential districts.' Beyond the enumerated examples, public disturbance noise also covers any sound that unreasonably disturbs or interferes with the peace, comfort and repose of owners or occupants of real property and that prompts complaints from two or more persons occupying separate residences. Residents are directed to report nighttime noise disturbances to the Pasco Police Department non-emergency line. Note that overall maximum sound-level limits (in decibels) are set separately in PMC 9.130.040, which adopts the Washington State environmental noise standards. These quiet-hour rules are local Pasco ordinances, not merely state law.
