RI H8039

Allows owners of substandard lots with multiple dwellings to subdivide so each principal dwelling building stands on its own lot through a minor subdivision process, without requiring additional zoning relief

Reduces the minimum lot size threshold for accessory dwelling units (ADUs) allowed by right from 20,000 square feet to 10,000 square feet

Clarifies ADU size limits: studio/one-bedroom units may be up to 900 sq. ft. or 60% of principal dwelling gross floor area (whichever is less); two+ bedroom units may be up to 1,200 sq. ft. or 60% of gross floor area

Establishes that attached single-family dwelling units may be subdivided onto individual lots at permitted density levels without increased requirements for lot coverage, lot size, lot width, frontage, or depth

Preserves municipalities' right to require year-round occupancy restrictions for rental ADUs, with such restrictions exempt from the 30-year limitation on restricted covenants
