An Act relative to safe building materials

This bill amends Massachusetts building codes to establish stricter safety requirements for new residential structures built with light frame construction, such as wood framing. It directly affects developers and builders creating multi-unit housing projects like apartments, hotels, and boarding houses. The key provisions mandate that any new residential building with more than two units using this construction method must be equipped with an automatic sprinkler system throughout. Additionally, the bill requires that fire partitions within these structures be made of noncombustible materials or fire-retardant treated wood with a minimum one-hour fire-resistance rating. These changes aim to enhance fire safety in residential developments by enforcing specific material and system standards.
