Twin Falls, ID Landscaping Rules: Weed Ordinances (2026)

Section 7-5-2 of the Twin Falls City Code is the weed and grass rule for the City of Twin Falls. Subsection (A) requires every owner, tenant or occupant of private property to cut and remove weeds and grass, and to clean and remove rubbish, as often as necessary to keep the property neat and to prevent weeds from seeding. The duty reaches past the lot line: it runs to the center of any street or alley along or in front of the property, including the parking within and the curbing abutting it.

The code prints no inch or foot limit for grass or weed height. The standard is the neatness and no-seeding language in subsection (A), so the test is the condition of the property rather than a measured blade length.

Enforcement starts with a notice. Under subsection (C) City employees can issue a warning notice for any violation, and the warning sets a reinspection date. If the violation is not corrected by that date, a civil penalty is assessed: $100 for the first violation, $200 for the second, and $300 for the third and subsequent violations during the same calendar year.

Subsection (B) lets the City do the work itself. If the owner, tenant or occupant fails or neglects to cut or remove the weeds, grass and rubbish, the City can have its officers or employees do it and assess the cost against the property as a lien. The assessment is certified to the County Assessor or other proper County officer and collected in the same manner as other Municipal taxes.

Subsection (D) adds criminal exposure on top of the civil penalties. Costs the city or another party incurs to bring the property into compliance can be charged as restitution in the criminal case. Section 7-5-4 declares the failure to cut and remove weeds, grass and rubbish a public nuisance. Section 7-5-3 separately requires treatment of tree and plant pests by April 25 each year.
