Full Breakdown
Salem Revised Code 93.020(d) lists construction as a noise disturbance per se: building, street, sidewalk, driveway, sewer and utility-line work is prohibited between 10 p.m. and 7 a.m. In unincorporated Marion County within the Salem-Keizer UGB, MCC 8.45.060(E)(3)(c) states daytime sound levels 'do not apply to sounds produced in commercial construction activity,' so daytime construction is generally allowed, but nighttime construction noise still triggers the plainly-audible and dB limits. Impact equipment such as pile drivers and pneumatic hammers is separately barred 10 p.m.–7 a.m. under SRC 93.020(j).
Violations & Fines
