The bill amends the Stille-DeRossett-Hale single state construction code act by adding a new section, 13h, which outlines specific requirements for converting existing buildings or structures into accessory dwelling units. According to the new provision, any such conversion must ensure that the building or structure has a foundation that meets the frost protection requirements set forth in the code.

However, there is an exception to this requirement. If the owner submits a building permit application that includes an attestation confirming that the building or structure was constructed at least 10 years prior to the application date, along with a statement from a structural engineer affirming that there is no significant frost heaving affecting the structural integrity, the frost protection requirement will not apply. This amendment aims to facilitate the conversion of older buildings into accessory dwelling units while maintaining safety standards.
