Quiet hours in Clark County, WA — also called the noise ordinance, nighttime noise rules, or residential quiet time — define the hours during which excessive noise is prohibited.
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.
CCC 9.14.010(8) targets nighttime street noise between 10:00 p.m. and 7:00 a.m. The county also adopts Washington's environmental noise standard: under WAC 173-60-040 a residential (Class A) receiving property may not exceed 55 dBA from another residence, reduced to 45 dBA between 10:00 p.m. and 7:00 a.m. Proof of exceeding the WAC 173-60 levels is prima facie evidence of a county violation. Incorporated cities like Vancouver set their own quiet-hours rules.
Violation of CCC 9.14.010 is a misdemeanor punishable by a $250 fine and/or up to 90 days in county jail; the sheriff enforces.
