What This Bill Proposed
Idaho Senate Bill 1280 prohibits cities and counties from banning duplexes and s in residential areas where single-family homes are allowed, voiding conflicting local ordinances and private property covenants starting July 1, 2026. The measure requires local governments to update their comprehensive plans and land use regulations to permit these multi-family housing types administratively without discretionary review. It also caps off-street parking requirements at one space per unit and bans higher impact or utility connection fees than those charged for single-family dwellings.
Property owners gain the legal right to build s and duplexes on any lot permitting single-family houses, while developers and residents can sue municipalities or covenant enforcers for damages and legal fees if restrictions are unlawfully enforced.
