Caldwell, ID Landscaping Rules: Grass Height Limits (2026)

The City of Caldwell handles tall grass and overgrown lawns through its nuisance-abatement code rather than a stated inch-by-inch height limit. Caldwell City Code Chapter 7, Article 11 (Nuisance Abatement; Appearance of Property) makes it unlawful for any owner, occupant, or person in charge of property to create or allow a nuisance on that property, or on the abutting street, sidewalk, parkstrip, or right-of-way area behind curbs and to the center of alleys and ditches (07-11-03). The city's separate property-maintenance standards require that all exterior property and premises be maintained in a clean, safe, and sanitary condition and free of weeds, trash, debris, and other nuisances in accordance with Chapter 7, Article 11. Caldwell's Code Compliance Division enforces these standards. Because the published sections describe overgrown vegetation generally rather than a confirmed numeric mowing threshold, residents who want the exact current cutoff should confirm directly with Code Compliance. Enforcement is complaint-driven: when an officer documents a nuisance, the city issues a written request for voluntary compliance giving roughly ten days to correct it before the city may abate the condition and bill the owner.
