Bill Information: H0643 – Heat Detection Devices in Residential Garages
Bill Summary
This bill amends Idaho’s building code enforcement statute to require heat detection devices in attached garages of new residential construction. For single-family homes and multiple-family dwellings up to two units receiving building permits on or after July 1, 2026, the bill mandates installation of heat detection devices with suitable temperature ratings in attached garages, interconnected with the home’s smoke alarm system. This requirement applies as a condition for maintaining the existing exemption from automatic fire sprinkler system requirements.
The bill also expands the definition of “multiple-family dwelling up to two (2) units” to include larger buildings if no more than two units share the same side of a two-hour fire wall, the fire wall extends from the lowest portion to the roof without penetrations, and the building permit was issued after July 1, 2026. This definitional change allows certain townhouse-style developments to qualify for the sprinkler exemption while still requiring the new heat detection devices in garages.
Overall Assessment
This bill imposes a new construction mandate on Idaho homebuilders and property owners, requiring heat detection devices in attached garages for all new residential construction beginning July 1, 2026. The requirement adds regulatory compliance costs and reduces property owners’ discretion over safety features in their homes. While framed as a condition for maintaining sprinkler exemptions, it represents an expansion of state building code requirements that increases construction costs without providing property owners the option to decline.
Rating Breakdown
ARTICLE I. RESPONSIBILITY IN GOVERNMENT (-1)
The bill creates a new government mandate requiring heat detection devices in attached garages for new residential construction: "such unit shall have a heat detection device with a suitable temperature rating installed in any attached garage." This adds regulatory requirements that property owners must comply with to obtain building permits, expanding government oversight of private construction decisions.
ARTICLE II. CITIZEN INVOLVEMENT IN GOVERNMENT (0)
The bill addresses building code requirements for residential construction and does not involve citizen participation in government, electoral processes, voting procedures, or civic engagement mechanisms.
ARTICLE III. EDUCATION (0)
The bill modifies building code requirements for residential dwellings and has no connection to education policy, school curriculum, parental rights in education, or educational institutions.
ARTICLE IV. AGRICULTURE (0)
The bill applies specifically to single-family homes and multiple-family dwellings and does not affect agricultural operations, farming practices, or agricultural buildings, which remain exempt from these code requirements under existing law.
ARTICLE V. WATER (0)
The bill concerns fire safety equipment in residential construction and has no connection to water rights, water management, water appropriation, or water policy.
ARTICLE VI. NATURAL RESOURCES AND ENVIRONMENT (0)
The bill addresses building safety codes for residential garages and does not involve natural resource management, environmental policy, federal lands, or conservation issues.
ARTICLE VII. ENERGY (0)
The bill requires heat detection devices in garages but does not address energy policy, energy production, energy independence, or energy conservation standards beyond existing code provisions.
ARTICLE VIII. IDAHO NATIONAL LABORATORIES (0)
The bill amends residential building codes and has no connection to the Idaho National Laboratory, nuclear research, or technology development activities.
ARTICLE IX. PRIVATE PROPERTY RIGHTS (-1)
The bill imposes a new state regulation that diminishes property owners' rights to develop their property as they choose. Property owners constructing new homes must now install heat detection devices in attached garages and interconnect them with smoke alarm systems, removing their discretion over these construction decisions and adding mandatory compliance costs.
ARTICLE X. STATE AND FEDERAL LANDS (0)
The bill regulates building codes for private residential construction and does not address state or federal land management, land ownership, or land use policies on public lands.
ARTICLE XI. WILDLIFE MANAGEMENT (0)
The bill concerns residential building safety requirements and has no connection to wildlife management, hunting, fishing, or predator control policies.
ARTICLE XII. ECONOMY (-1)
The bill adds a new regulatory requirement on residential construction that increases compliance costs for builders and homeowners. The mandate for heat detection devices interconnected with smoke alarm systems represents an additional regulatory burden that must be met for all new construction, directly conflicting with principles of reducing excessive regulatory requirements.
ARTICLE XIII. HEALTH AND WELFARE (0)
While the bill addresses residential safety through fire detection equipment, it does not involve healthcare delivery systems, health insurance, patient rights, medical decisions, or welfare programs as defined by this metric.
ARTICLE XIV. AMERICAN FAMILY (0)
