Bill > HB4850

This bill requires owners, operators, or builders of certain multi-family and commercial buildings to install automatic fire sprinkler systems in parking areas designated for electric vehicles (EVs). Specifically, for new buildings, sprinkler systems must be installed during initial construction for EV parking spaces, and for existing buildings constructed before the bill's effective date, owners have 180 days to install such systems. The bill applies to multi-family dwellings and commercial structures but explicitly excludes single-family homes and 1-2 family detached dwellings. An "automatic fire sprinkler system" is defined as an integrated piping system that activates with heat from a fire and discharges water to extinguish the fire, designed according to fire protection engineering standards. An "electric vehicle" is defined as a vehicle propelled solely by electrical energy and incapable of using gasoline, diesel, or alternative fuels. The joint committee on administrative rules will be responsible for establishing specific standards and requirements for these sprinkler system installations, reflecting growing safety concerns about potential fire risks associated with electric vehicle charging infrastructure.
