About 40B

G.L. c. 40B, §§ 20-23 – known as Chapter 40B or the Comprehensive Permit Law – is a state law that was enacted in 1969 to facilitate construction of low- or moderate-income housing. It establishes a consolidated local review and approval process (known as a “comprehensive permit”) that empowers the zoning board of appeals (ZBA) in each city and town to hold hearings and make binding decisions that encompass all local ordinances or bylaws and regulations. In certain circumstances, the ZBA’s comprehensive permit decision may be appealed to the Massachusetts Housing Appeals Committee (HAC), which has the power to affirm, modify, or overturn local decisions.
