Chapter 40B Law & Regulations

The Comprehensive Permit Statute under M.G.L. Chapter 40B Sections 20-23 was adopted in 1969 by the Massachusetts Legislature to “address the shortage of low- and moderate-income housing in Massachusetts and to reduce regulatory barriers that impeded the development of such housing.” 
Subsequently, the Massachusetts Department of Housing and Community Development (DHCD) issued 760 CMR 56.00, which “set forth comprehensive standards and procedures” governing Comprehensive Permits, addressed the Subsidized Housing Inventory (SHI), and advanced the statutory purposes of M.G.L. Chapter 40B Sections 20-23 “by clarifying the procedures of the expedited review process, and by otherwise addressing recurring questions of interpretation.” Section 56.03 of 760 CMR defines the methods for measuring progress toward local housing goals.
