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 stipulates that local building regulations cannot impose such a requirement for these types of residential properties.

By establishing these provisions, the bill aims to reduce regulatory burdens on smaller residential developments, ensuring that the installation of fire protection sprinkler systems is not mandated for smaller series of attached homes. This change reflects a shift in policy regarding fire safety requirements for specific residential configurations.
