What is the purpose of the 40B law in Massachusetts?

The 40B law in Massachusetts, formally known as Chapter 40B of the General Laws, is specifically designed to encourage the development of affordable housing. The primary goal of this legislation is to increase the availability of affordable homes in areas where such housing is needed, particularly in communities where there may be a scarcity of housing options for low- and moderate-income residents.

Under this law, developers can apply for a comprehensive permit to bypass certain local zoning regulations if a specified percentage of the proposed units are designated as affordable. This mechanism seeks to facilitate the construction of housing that meets the affordability criteria, thereby addressing the housing crisis and promoting diversity in the housing stock across the state. The focus on affordable housing is crucial for improving accessibility and ensuring that all residents have equitable housing options.

The other options do not align with the primary intent of the 40B law. While it may indirectly influence commercial development or zoning laws due to the nature of permits, these are not the central objectives of the statute. Additionally, it does not deal with controlling property taxes, which is a separate issue within municipal finance.
