Kitsap County, WA Noise Ordinances: Construction Hours (2026)

Kitsap County Code Chapter 10.28 does not list a fixed daily start and stop clock for construction crews the way some cities do; instead it works by exemption. § 10.28.070, titled 'Exemptions from Section 10.28.040 relating to noise reception in Class A EDNAs and from Section 10.28.145,' exempts sounds originating from temporary construction sites as a result of construction activity, along with sounds from forest harvesting and silvicultural activity, from both the numeric decibel table in § 10.28.040 and the public disturbance noise rules in § 10.28.145.

The exemption carries one carve-out written directly into its opening sentence: it does not apply insofar as those provisions relate to the reception of noise within Class A EDNAs, the county's residential, agricultural, forestry and undeveloped-land zones, between the hours of 10:00 p.m. and 7:00 a.m. In effect, construction noise is unregulated by these two sections during the day and at any hour outside that window in a non-Class A zone, but once it reaches a home or other Class A property between 10:00 p.m. and 7:00 a.m. it loses its exemption and is judged against the same nighttime-reduced decibel table used in § 10.28.040(b), and can also be charged as a public disturbance noise under § 10.28.145.

A separate exemption in § 10.28.050 additionally protects sounds from temporary home maintenance and repair projects between 7:00 a.m. and 10:00 p.m. This construction-hours structure applies only to unincorporated Kitsap County; Bremerton, Port Orchard, Poulsbo and Bainbridge Island set their own construction-hour rules.
