Bill Information: S1354 – Idaho ADU Zoning & HOA Restriction Reform
Bill Summary
Senate Bill 1354 makes two major structural changes to Idaho law governing accessory dwelling units (ADUs). First, it rewrites Section 55-3212 to prohibit HOAs from limiting or banning ADUs on any property within their jurisdiction unless the affected property owner expressly agrees in writing to such a restriction. HOAs retain the ability to enforce pre-existing covenants that were in place when a property owner acquired their interest, and may still adopt reasonable rules on size, height, setbacks, parking, and bedroom counts.
Second, the bill creates new Section 67-6541, which bars cities from prohibiting ADUs in any residential zoning area and requires all Idaho cities with populations over 5,000 to update their comprehensive plans and land use regulations by October 1, 2026. Those updates must allow one internal ADU within a single-family dwelling and one detached ADU per lot, ban mandatory off-street parking requirements for ADUs, cap impact and utility connection fees at levels no higher than those for other single-family dwellings, prohibit size limits below 1,000 square feet or 75% of the primary dwelling, limit rear and side setbacks to no more than four feet, and eliminate owner-occupancy requirements for either the primary or accessory unit.
Compliant ADU projects must receive administrative approval as a matter of right, without discretionary review. Historic districts designated under Section 67-4607 are exempt from the city-level mandates. The bill takes effect July 1, 2026, under an emergency declaration.
Overall Assessment
This bill directly expands the rights of Idaho property owners to build and rent accessory dwelling units by stripping HOAs of the power to ban ADUs without written owner consent and forcing cities over 5,000 in population to remove the most common regulatory barriers — excessive setbacks, parking mandates, owner-occupancy rules, and inflated fees — that have historically blocked ADU construction. Property owners gain a concrete new tool to add rental income, house family members, or increase property value without seeking discretionary approval. The state mandate on cities, however, imposes compliance costs and regulatory overhaul obligations on local governments without providing funding to carry them out.
Rating Breakdown
ARTICLE I. RESPONSIBILITY IN GOVERNMENT (-1)
Section 67-6541(2) requires every Idaho city with a population over 5,000 to amend its comprehensive plan and land use regulations by October 1, 2026, a significant administrative undertaking that must follow the full notice-and-hearing process under Section 67-6509. The state imposes this mandate but provides no funding to cover the legal, planning, and administrative costs cities will incur to comply, shifting the financial burden to local governments and their taxpayers.
ARTICLE II. CITIZEN INVOLVEMENT IN GOVERNMENT (0)
This bill governs land use zoning and HOA covenant enforcement. It has no bearing on elections, voting procedures, civic participation, or government transparency.
ARTICLE III. EDUCATION (0)
The bill's provisions are confined to residential zoning and HOA regulations. It has no connection to school funding, curriculum, parental rights in education, or any other education policy matter.
ARTICLE IV. AGRICULTURE (0)
The bill applies to residential zoning areas within cities and regulates ADUs on single-family lots. It does not address farming, ranching, agricultural water rights, or rural land use.
ARTICLE V. WATER (0)
The bill contains no provisions related to water rights, prior appropriation, reservoirs, or state sovereignty over water resources. Its scope is limited to residential land use regulation.
ARTICLE VI. NATURAL RESOURCES AND ENVIRONMENT (0)
The bill regulates ADU construction on private residential lots within city limits. It does not address environmental policy, federal land management, forest health, or natural resource utilization.
ARTICLE VII. ENERGY (0)
The bill addresses residential zoning and HOA restrictions. It contains no provisions related to energy production, energy independence, hydroelectric power, or utility regulation.
ARTICLE VIII. IDAHO NATIONAL LABORATORIES (0)
The bill concerns residential land use and HOA governance. It has no connection to the Idaho National Laboratory, nuclear research, or technology development.
ARTICLE IX. PRIVATE PROPERTY RIGHTS (1)
The bill directly expands property owners' development rights on two fronts. Section 55-3212 bars HOAs from restricting ADUs without the property owner's written consent, and Section 67-6541 prohibits cities from banning ADUs in residential zones while eliminating common regulatory barriers such as owner-occupancy requirements, excessive setbacks, mandatory parking, and inflated impact fees. Property owners gain the right to build and rent ADUs as a matter of right through administrative approval, without discretionary review.
ARTICLE X. STATE AND FEDERAL LANDS (0)
The bill applies exclusively to private residential property within city jurisdictions. It does not address the ownership, management, or transfer of state or federal lands.
ARTICLE XI. WILDLIFE MANAGEMENT (0)
The bill governs residential zoning and HOA covenants. It has no provisions related to wildlife management, hunting, fishing, or predator control.
ARTICLE XII. ECONOMY (1)
By requiring cities to eliminate excessive fees, parking mandates, owner-occupancy rules, and overly restrictive size and setback requirements, the bill reduces the regulatory cost of ADU construction and opens a new avenue for small-scale residential development and rental income. Section 67-6541(3) guarantees administrative approval as a matter of right for compliant projects, removing the delay and uncertainty of discretionary review that has historically made ADU development economically unviable for many property owners.
ARTICLE XIII. HEALTH AND WELFARE (0)
The bill addresses land use zoning and HOA regulations. It contains no provisions related to healthcare, health insurance, welfare programs, or medical decision-making.
ARTICLE XIV. AMERICAN FAMILY (0)
While ADUs can practically serve multigenerational households, the bill does not specifically target family housing arrangements, parental rights, marriage, or any of the family-focused policy areas this metric addresses. The bill's ADU definition and permissions are broadly written for any residential use.
ARTICLE XV. OLDER AMERICANS (0)
The bill does not specifically address older Americans, retirement security, or age-related services. Its ADU provisions apply broadly to all property owners regardless of age.
ARTICLE XVI. LAW AND ORDER WITH JUSTICE (0)
The bill operates in the civil domain of land use and HOA governance. It has no connection to criminal justice, gun rights, drug policy, sentencing, or law enforcement.
ARTICLE XVII. NATIONAL DEFENSE – SECURING THE BORDER (0)
The bill concerns residential zoning within Idaho cities. It has no provisions related to national defense, military affairs, border security, veterans, or immigration enforcement.
ARTICLE XVIII. ELECTION OF JUDGES AND IDAHO SUPREME COURT JUSTICES (0)
The bill addresses land use regulation and HOA covenants. It contains no provisions related to judicial elections, judicial selection methods, or constitutional interpretation.
ARTICLE XIX. RELIGIOUS LIBERTY (0)
The bill governs secular residential zoning and HOA restrictions. It has no connection to religious freedom, conscience protections, or government interference in religious practice.
