Ada County, ID Public Conduct: Public Urination (2026)

Ada County Code section 2-3-5, found in the Public Safety Complex chapter, states that to promote and protect public health, it is a misdemeanor for any person to excrete human waste, except in a designated restroom facility, on any Ada County owned or leased property. The section defines 'excretion' as the discharge of human waste from the body, including the acts of defecation and urination, and defines 'human waste' as human feces or human urine. Although the chapter's title refers specifically to the Public Safety Complex on Barrister Drive in Boise, the operative text of section 2-3-5 is written to cover any property the county owns or leases, not just that one campus, so the same rule follows county buildings, offices, and grounds elsewhere in the unincorporated county.

Enforcement runs through section 2-3-7 rather than a stand-alone penalty clause: a person who violates any provision of the chapter, unless the chapter specifically calls the violation an infraction, is guilty of a misdemeanor and subject to the penalties in Idaho Code sections 18-111 and 18-113. Because the health-and-safety subsection carries no infraction label of its own, a public urination or defecation citation under this chapter is prosecuted as a full misdemeanor rather than a lesser infraction.
