Chapter 40B is one of the state's most successful affordable housing production tools, with over 70,000 homes created across the state.
Also known as the Comprehensive Permit Law, Chapter 40B was enacted in 1969 to help expand the number of communities and neighborhoods where households with low and moderate incomes could secure a safe, affordable home. In 2010, 58% of voters in Massachusetts overwhelmingly supported keeping Chapter 40B as a tool for providing affordable homes for people of all ages.
