Senate Bill 1352 would create a new section of Idaho law governing “starter home subdivisions.” It would prohibit cities from banning these subdivisions in residential zoning areas and would require cities to update their comprehensive plans and land use regulations by February 1, 2027, to allow them in residential districts, with exceptions for historic districts and historic properties. The bill defines a starter home subdivision as a residential subdivision of at least four acres designed to support attainable homeownership through smaller single-family detached homes on compact lots.
The bill also sets statewide limits on local regulation of these subdivisions. For qualifying projects, cities could not require minimum lot sizes above 1,500 square feet, front or rear setbacks above 15 feet, side setbacks above 5 feet, front widths above 30 feet, or lot depths above 70 feet, unless site conditions or infrastructure constraints make those standards unfeasible. It further restricts cities from charging permit, development impact, or utility connection fees that exceed those imposed on other single-family subdivisions, while allowing local incentives for compliance with the smaller-lot standards. The bill applies only to cities with populations over 10,000 and does not override health, safety, environmental, floodplain, utility, road access, or easement-related laws.
In practical terms, the bill would limit municipal zoning and subdivision authority in larger Idaho cities and require local land-use codes to accommodate a new class of lower-cost housing development. It would affect city planning departments, developers, and property owners by standardizing minimum development requirements for starter home projects and by preventing local bans on this housing type. The bill would take effect July 1, 2026, as an emergency measure.
The voting history suggests the bill drew meaningful support but also notable opposition. It passed the Senate 25-10 and the House 35-32, indicating a divided but ultimately successful path through both chambers. The narrow House margin in particular suggests the measure was controversial, likely because it limits local control over zoning and development standards while being framed as a housing affordability tool.
The main point of contention is the balance between housing affordability and municipal autonomy. Supporters appear to favor the bill as a way to expand attainable homeownership and encourage smaller, more affordable lots in growing cities. Opponents are likely concerned about state preemption of local planning decisions, possible infrastructure strain, and the extent to which cities should be required to accommodate denser or smaller-lot development. The bill’s explicit carve-outs for historic areas and infrastructure limitations appear designed to address some of those concerns.
This bill would add Section 67-6541 to Title 67 of the Idaho Code and would preempt local ordinances that ban starter home subdivisions in residential zoning areas in cities over 10,000 population. It would require affected cities to amend comprehensive plans and land use regulations to permit these subdivisions and would impose statewide limits on lot size, setbacks, lot dimensions, and certain fees for qualifying projects, while preserving existing health, safety, environmental, and infrastructure-related regulations.
The bill appears to have received mixed but sufficient support, with passage in both chambers but relatively close votes, especially in the House. The overall tone suggests support for housing affordability and attainable homeownership, but also significant concern about restricting local zoning authority and the practical effects on city planning and infrastructure.
The central controversy is whether the state should override city zoning rules to force accommodation of starter home subdivisions. Supporters likely view the bill as a necessary response to housing affordability and supply constraints, while opponents likely object to the loss of local control, the mandated lot and setback standards, and the potential burden on infrastructure and municipal planning. Historic districts, infrastructure adequacy, and the scope of fee limits are the main areas where the bill tries to narrow that conflict.
