Pasco, WA Noise Ordinances: Leaf Blower Rules (2026)

Pasco does not appear to have a dedicated leaf-blower ordinance (no gas-blower ban, model restrictions or special hours just for blowers). Instead, leaf blowers fall under the general noise rules in PMC Chapter 9.130. PMC 9.130.030 lists, among prohibited public disturbance noises, sounds made by operating mechanically powered tools, expressly including lawn or garden tools, fans or blowers, between 10:00 p.m. and 7:00 a.m. in a manner that causes a noise disturbance across a residential boundary. The practical effect is that leaf blowers and similar yard equipment should not be run during the nighttime quiet window (10pm-7am) near homes, but daytime operation is generally permitted. During the day, blower use is still subject to the maximum permissible environmental noise levels in PMC 9.130.040 (which adopt the Washington State standard, WAC 173-60). Notably, the Washington noise rules exempt sounds from temporary residential maintenance and yard-care projects between 7:00 a.m. and 10:00 p.m., which is consistent with allowing routine daytime leaf-blowing. Because there is no blower-specific section in the PMC, this entry honestly reflects that Pasco regulates blowers only through its general noise ordinance and the adopted state standards.
