Bill Information: S1352 – Idaho Starter Home Subdivision Act 2026
Bill Summary
Senate Bill 1352 adds Section 67-6541 to Idaho Code, prohibiting cities with populations over 5,000 from banning starter home subdivisions—defined as proposed new single-family dwelling developments on parcels of at least four acres—in any residential zoning area. By October 1, 2026, qualifying cities must amend their comprehensive plans and land use regulations to cap minimum lot sizes at 1,400 square feet, limit front and rear setbacks to 15 feet and side setbacks to 5 feet, restrict required lot front widths to 30 feet and depths to 70 feet, and allow densities of at least 12 dwelling units per acre. Cities are also barred from charging permit, development impact, or utility connection fees for starter home subdivisions that exceed what they charge for standard single-family subdivisions, though they may offer fee reductions or waivers as builder incentives.
The bill preserves existing building codes, fire safety standards, floodplain regulations, water and sewer laws, environmental hazard protections, and right-of-way setback requirements, ensuring that health, safety, and infrastructure standards remain in force. Lot depth limits may be exceeded where topography, lot shape, or environmental or infrastructure constraints require it, and density minimums may be relaxed where infrastructure limitations or environmental conditions make higher density infeasible. Historic districts as defined under Section 67-4607, Idaho Code, are exempt from the bill’s requirements.
The bill takes effect July 1, 2026, under an emergency declaration, giving cities roughly three months to bring their comprehensive plans and land use codes into compliance. A severability clause ensures that if any individual provision is struck down, the remainder of the law stays intact.
Overall Assessment
This bill directly attacks exclusionary zoning by stripping Idaho cities of the authority to block small-lot, high-density single-family development, opening the door to significantly more affordable entry-level housing in communities across the state. First-time homebuyers and lower-income families stand to benefit most, as the mandated lot size, setback, and density standards make it economically viable for builders to construct homes on smaller parcels at lower per-unit land costs. Cities, however, bear the compliance burden: they must rewrite comprehensive plans and land use codes within roughly three months of the bill’s effective date, with no state funding provided to cover the staff time, legal review, and public hearing costs that process requires.
Rating Breakdown
ARTICLE I. RESPONSIBILITY IN GOVERNMENT (-1)
The bill imposes a direct state mandate on cities, requiring each qualifying city governing board to amend its comprehensive plan and land use regulations by October 1, 2026, under subsection (2) of the new Section 67-6541. This mandate carries real administrative costs—staff time, legal drafting, and public hearings under the notice procedures of Section 67-6509—but the bill provides no state funding to offset those expenses, placing the financial burden entirely on local governments.
ARTICLE II. CITIZEN INVOLVEMENT IN GOVERNMENT (0)
The bill governs residential zoning standards and local land use regulation, not electoral processes, civic participation, or voting. While it does require cities to follow existing public notice and hearing procedures under Section 67-6509 when amending their plans, it neither expands nor restricts citizen involvement in government.
ARTICLE III. EDUCATION (0)
The bill exclusively addresses residential zoning and housing subdivision standards. It contains no provisions related to schools, curriculum, parental rights in education, school funding, or any other education policy matter.
ARTICLE IV. AGRICULTURE (0)
The bill applies to land zoned for single-family residential use within cities with populations over 5,000. It does not address farming, ranching, agricultural water rights, rural land use, or any other agricultural policy.
ARTICLE V. WATER (0)
While subsection (3)(b) of the new section preserves existing laws governing water, sewer, and storm drainage as infrastructure prerequisites for required densities, the bill does not modify water rights, prior appropriation doctrine, inter-basin transfers, or state water management policy.
ARTICLE VI. NATURAL RESOURCES AND ENVIRONMENT (0)
Subsection (3)(c) explicitly preserves existing laws protecting environmental hazards, aquifer recharge zones, steep slopes, and critical habitat, ensuring those protections are not overridden by the new zoning mandates. The bill does not create new environmental regulations or alter natural resource management policy.
ARTICLE VII. ENERGY (0)
The bill addresses residential land use and zoning standards exclusively. It contains no provisions related to energy production, electrical rates, hydroelectric or nuclear power, or energy independence.
ARTICLE VIII. IDAHO NATIONAL LABORATORIES (0)
The bill concerns municipal zoning for single-family housing subdivisions and has no connection to the Idaho National Laboratory, nuclear research, or energy technology development.
ARTICLE IX. PRIVATE PROPERTY RIGHTS (1)
Subsection (1) of the new section directly prohibits cities from banning starter home subdivisions in residential zones, and subsections (2)(a) through (2)(e) strip away the most common regulatory tools cities use to block small-lot development—excessive minimum lot sizes, oversized setbacks, restrictive lot dimensions, and artificially low density caps. By removing these barriers, the bill expands a property owner's practical ability to develop residential land in ways that local zoning had previously foreclosed.
ARTICLE X. STATE AND FEDERAL LANDS (0)
The bill applies exclusively to privately owned land proposed for single-family residential subdivision within city limits. It does not address state or federal land ownership, management, or transfer of public lands to state control.
ARTICLE XI. WILDLIFE MANAGEMENT (0)
The bill governs urban and suburban residential zoning and contains no provisions related to fish and game management, hunting, fishing, or wildlife habitat policy beyond preserving existing critical habitat protections as a carve-out in subsection (3)(c).
ARTICLE XII. ECONOMY (1)
By prohibiting cities from imposing lot sizes above 1,400 square feet, excessive setbacks, and inflated density restrictions, the bill removes regulatory barriers that have historically made entry-level homebuilding economically unviable in Idaho cities. Subsection (2)(f) further prevents cities from using discriminatory fee structures to price starter home developers out of the market, lowering the cost of production and broadening the housing supply available to working families and first-time buyers.
ARTICLE XIII. HEALTH AND WELFARE (0)
The bill addresses zoning and land use regulation for residential subdivisions. It does not modify healthcare delivery, health insurance, welfare programs, or medical decision-making, and its preservation of building codes and safety standards in subsection (3)(a) keeps existing health and safety floors intact.
ARTICLE XIV. AMERICAN FAMILY (0)
While the bill targets single-family dwelling subdivisions and could indirectly benefit families seeking affordable homeownership, it contains no provisions addressing family structure, parental rights, marriage, or the social policy topics covered by this metric.
ARTICLE XV. OLDER AMERICANS (0)
The bill focuses on starter home subdivision standards for new residential development and contains no provisions specifically affecting older Idahoans, retirement security, or services for seniors.
ARTICLE XVI. LAW AND ORDER WITH JUSTICE (0)
The bill operates entirely within the domain of municipal land use and zoning law. It contains no provisions related to criminal justice, firearms, law enforcement, incarceration, or state sovereignty regarding immigration enforcement.
ARTICLE XVII. NATIONAL DEFENSE – SECURING THE BORDER (0)
The bill addresses residential zoning within Idaho cities and has no connection to national defense, military readiness, veterans' affairs, or border security policy.
ARTICLE XVIII. ELECTION OF JUDGES AND IDAHO SUPREME COURT JUSTICES (0)
The bill concerns housing subdivision standards and local land use regulation. It contains no provisions related to judicial selection, court procedures, or constitutional interpretation.
ARTICLE XIX. RELIGIOUS LIBERTY (0)
The bill governs residential zoning and housing development standards exclusively. It contains no provisions affecting religious practice, conscience protections, or government interference with religious institutions.
