This bill mandates that the state building code commissioner implement a prohibition on the required installation of fire protection sprinkler systems in attached single-family residences that consist of fewer than seven units. This means that such installations will not be a requirement at the state level for these types of residential properties.

Additionally, the bill ensures that local building regulations cannot impose a requirement for the installation of fire protection sprinkler systems in the same category of attached single-family residences. This creates a uniform standard across the state and local jurisdictions, preventing any local authority from mandating sprinkler systems in smaller residential developments.
