Kootenai County, ID Noise Ordinances: Quiet Hours (2026)

Because the unincorporated area has no city noise ordinance of its own, loud parties, amplified music and similar nighttime racket are handled through Idaho Code section 18-6409(1), the state's general disturbing-the-peace statute, enforced by the Kootenai County Sheriff's Office. The statute is broader than a simple decibel or curfew rule: it covers anyone who 'maliciously and willfully disturbs the peace or quiet of any neighborhood, family or person, by loud or unusual noise, or by tumultuous or offensive conduct, or by threatening, traducing, quarreling, challenging to fight or fighting,' and separately criminalizes firing a gun or pistol or using vulgar, profane or indecent language in the presence of children in a loud and boisterous manner.

Unlike a city ordinance keyed to a fixed nighttime window, section 18-6409 carries no clock-time trigger; a violation can occur at any hour, so a loud daytime confrontation qualifies exactly the same as an all-night stereo. A charge is a misdemeanor, and because the statute doesn't set its own fine or jail term, Idaho's default misdemeanor punishment in section 18-113 applies unless another statute controls. The law is a criminal statute, not a civil citation scheme, so it is prosecuted in Kootenai County's court system rather than appealed administratively; a person cited retains the same right to contest the charge and require the state to prove malicious and willful conduct that any other misdemeanor defendant has.
