Rhode Island has introduced a groundbreaking law aimed at accelerating the development of accessory dwelling units (ADUs), colloquially known as "granny flats" or "in-law apartments". Signed by Democratic Governor Dan McKee on June 25, the law allows homeowners to establish one ADU on their owner-occupied property. Advocates view this as a pivotal move in addressing the state's housing shortage by offering more affordable rental options and supporting property ownership stability.

To ensure the law's efficacy, Rhode Island prohibits ADUs from being used as short-term rentals, aligning with similar measures in states like New York. There, Governor Kathy Hochul allocated $59 million to assist low- and middle-income homeowners in constructing or upgrading ADUs. Massachusetts is also advancing legislative efforts to allow ADU construction on single-family zoned properties, reflecting a broader trend toward enhancing housing availability amid rising costs.

Boston, responding to soaring housing prices, mirrors Rhode Island's statewide efforts to streamline ADU creation. The law mandates that ADUs meet residency requirements and adhere to building codes, promoting responsible development in residential areas. June Speakman, chair of Rhode Island's House Commission on Housing Affordability, underscores ADUs' role in expanding housing options, especially for ageing adults seeking downsizing opportunities within familiar communities.

Catherine Taylor, AARP Rhode Island's state director, emphasises ADUs as vital for housing inclusivity, catering to diverse income levels and life stages. Harvard's Joint Center for Housing Studies reports the urgent need to accommodate an ageing population with limited financial resources, advocating for ADUs as innovative solutions to evolving housing needs
