This bill mandates that the state building code commissioner implement a prohibition on the installation of fire protection sprinkler systems in residential properties with fewer than seven units. Additionally, it prevents local building regulations from imposing requirements for such sprinkler systems in these smaller residences.

By establishing these provisions, the bill aims to streamline regulations and reduce the financial burden on owners of smaller residential properties, ensuring that they are not mandated to install fire protection systems that may be deemed unnecessary for their scale.
