Summary
Unincorporated Clark County has no single fixed "quiet hours," but yelling, shouting, whistling or singing near a street between 10 p.m. and 7 a.m. is a public disturbance noise, and state WAC 173-60 limits drop 10 dBA (to 45 dBA at residences) during those same hours.
Between the hours of 10:00 p.m. and 7:00 a.m. the noise limitations of the foregoing table shall be reduced by 10 dBA for receiving property within Class A EDNAs.
