Lacey, WA Noise Ordinances: Quiet Hours (2026)

The City of Lacey sets its nighttime noise hours inside the environmental performance standards of Chapter 16.57. Section 16.57.030(C)(2) provides that between 10:00 p.m. and 7:00 a.m. the limits in Table 16T-14 are reduced by 10 dBA for receiving property within Class A EDNAs. Under subsection B, all living areas are Class A, so the night reduction protects homes and, because public and institutional areas are also Class A, those uses too. The daytime figure printed in the table for a Class A source at a Class A receiving property is 55 dBA, and the code states the reduction as 10 dBA rather than as a new number.

The short-burst allowances in subsection (C)(3) still apply at any hour of the day or night: 5 dBA over for a total of 15 minutes in any one-hour period, 10 dBA for a total of 5 minutes, or 15 dBA for a total of 1.5 minutes.

Construction has its own clock. LMC 14.38.010 makes it unlawful to conduct outside construction activities regulated by Title 14 between nine p.m. and seven a.m. in any residential zone or any area directly abutting a residential zone. The only carve-out is emergency repair of utilities or streets, or construction of utilities or streets where operations are necessary during those hours to promote the safety of the traveling public. Section 16.57.040(G) adds that temporary construction vibration is restricted to the hours between 7:00 a.m. and 9:00 p.m.

For everyday disturbances, LMC 9.52.010(E) declares a public nuisance any loud noise from any source on residentially zoned property that disrupts the peace and comfort of the occupants of residential dwellings. That subsection prints no clock hours and no decibel figure, so the test is disruption of the peace and comfort of neighbors. Subsection (A) of the same section reaches motorcycles and other vehicles operated so as to create an unreasonable disruption of the peace and comfort of residents.
