An Act to improve the accuracy of the counting of existing affordable housing stock

This bill amends Massachusetts' Chapter 40B law to clarify how affordable housing is counted. It redefines "low or moderate income housing" to explicitly include federally or state-subsidized housing built or operated by public agencies, nonprofits, or limited-dividend groups. Crucially, it adds that 50% of homes in manufactured housing communities (as defined in Chapter 140) must be counted toward a city or town's affordable housing threshold, using documentation from the Executive Office of Housing and Livable Communities' inventory. This change directly affects cities and towns required to meet affordable housing thresholds under Chapter 40B by expanding the types of housing that count toward that requirement.
