S1352 Require Cities to Allow Starter Home Subdivisions

SUPPORT - This legislation requires Idaho cities with populations over 10,000 to allow “starter home subdivisions” in residential zones. It defines these as smaller-lot developments (generally ≤1,500 sq ft per lot) designed to reduce costs and expand access to homeownership. The bill limits local zoning requirements—such as lot size, setbacks, and fees—to make these projects feasible, while still allowing exceptions for infrastructure, environmental constraints, and public safety.

The bill will increase housing supply, particularly entry-level homes, by lowering regulatory barriers and development costs. This will improve affordability at the lower end of the market and provide more options for first-time buyers, especially in growing cities.

This meaningful pro-supply step should expand starter home options and modestly improve affordability, but it is not a complete solution to Idaho’s housing challenges.
