Spokane Valley, WA Noise Ordinances: Quiet Hours (2026)

Spokane Valley does not have a stand-alone noise-decibel ordinance with a single nightly curfew. Instead, noise is handled as a public nuisance under SVMC 7.05.040(K)(1), which makes it unlawful to allow any noise that, originating within a residential zone, intrudes onto another person's property and exceeds the maximum permissible environmental noise levels adopted by the state in Chapter 173-60 WAC. The code specifically lists amplified sound from radios, televisions, musical instruments and sound amplifiers, as well as noise from starting, operating, repairing, rebuilding or testing vehicles, off-highway machinery, equipment or internal combustion engines. SVMC 7.05.040(K)(2) exempts categories such as emergency equipment, aircraft, railroads, parades, agriculture, solid-waste collection and warning devices. Two time-limited exemptions effectively create a quiet-hours framework: under SVMC 7.05.040(K)(3), sounds from temporary residential repair or maintenance projects are exempt only between 7:00 a.m. and 10:00 p.m., and under SVMC 7.05.040(K)(4) construction, quarrying and mining noise is exempt only between 7:00 a.m. and 10:00 p.m. (or beyond 1,000 feet of any residence). Outside those windows, such activity loses its exemption and can be cited as a nuisance. Enforcement is administrative under Chapter 17.100 SVMC. The state WAC limits the city incorporates set maximum permissible noise levels by zone and are stricter at night.
