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. Additionally, it prevents local building regulations from imposing similar requirements for these types of residential properties.

By establishing this prohibition, the bill aims to reduce the regulatory burden on developers and homeowners of smaller attached single-family residences, thereby potentially lowering construction costs and encouraging the development of such housing.
