The bill amends the Rhode Island Rehabilitation Building and Fire Code for Existing Buildings and Structures to include existing residential dwellings for one, two, or three families, removing their current exclusion. It introduces a new legislative finding that emphasizes the purpose of the chapter to encourage the continued use and reuse of existing buildings and structures. The bill also establishes that the rehabilitation building and fire code shall apply to these residential dwellings, and any laws, rules, or regulations that previously excluded one-family, two-family, or three-family residential dwellings from the applicability of the code are repealed. This act will take effect upon passage.
