A 2024 law and a 2025 assistance program have spurred a flurry of ADU projects across the state.
Massachusetts communities have seen a growing number of accessory dwelling unit (ADU) permits after a new law helped streamline permitting for backyard cottages, garage apartments, and other similar housing types.
As Christian M. Wade explains in The Eagle-Tribune, “There were 1,639 applications last year for so-called accessory dwelling units, also known as “granny flats,” on residential properties statewide, with 1,224 projects permitted by local building departments, according to the state Executive Office of Housing and Livable Communities.”
According to an article by Michael Vyskocil for Boston’s 92.9 HD2, an August 2024 state bill authorized ADUs by-right in single-family zoning district across the state. “In December 2025, Healey rolled out a new Massachusetts Housing Partnership program to assist homeowners with building ADUs, an initiative supported by $10 million in available funding.”
