Chapter 40B, Secs. 20–23) was enacted in 1969 to promote the construction of low- and moderateincome housing. The law envisions that municipalities will work with developers to create affordable housing for individuals who would otherwise not be able to afford such an opportunity. The Comprehensive Permit Law also allows for an expedited administrative appeal to the HAC whenever a comprehensive permit is denied by a municipality or granted with conditions that might render construction of the proposed housing uneconomic and therefore impractical to build. A decrease in available buildable land, an increase in restrictive local regulations, and most importantly, a change in the availability of qualifying funding sources, have all led to an intensified interest by developers in the use of the comprehensive permit process as a means by which to develop new housing throughout the Commonwealth.
