Construction hours in Clackamas County, OR — sometimes called construction noise rules or contractor work-hour ordinances — set when contractors can run power tools, hammers, and heavy equipment.
In unincorporated Clackamas County, construction, demolition, alteration, or repair of buildings and excavation of streets is prohibited except between 7 a.m. and 10 p.m. Power tools like chain saws, drills, and lawnmowers share the same 7 a.m.-10 p.m. window.
Clackamas County Code 6.05.040(B)(11) makes it a per se violation to run construction, demolition, alteration, repair, or street/highway excavation outside 7 a.m. to 10 p.m. Section 6.05.060(I) separately exempts construction activity and hand/power tools (drills, chain saws, lawnmowers, saws, hammers) during those same hours. County or state road repair may run overnight (10 p.m.-7 a.m.) only when the public welfare makes daytime work impractical (6.05.060(J)). Cities set their own construction hours within their limits.
Off-hours construction noise is a per se violation citable by the Sheriff. Respond within 14 days by paying the Board-set fine or requesting a compliance hearing under Code Ch. 2.07.
