HB 313 Utah House · 2025 General Session

Construction Industry Amendments

HB 313 updates Utah's State Construction Code to align with the latest International Residential Code (IRC) and National Electrical Code (NEC) standards. It removes specific water heater regulations in certain areas and resolves conflicts with another bill (H.B. 175) through a coordination clause. This affects builders, contractors, and homeowners by updating safety and construction requirements to match current national standards. The bill makes technical adjustments to code references without adding new costs or funding. It does not create new regulations but modernizes existing ones for consistency with industry practices.
