An Act adjusting area median income based on zip code

This bill requires Massachusetts to calculate area median income using specific zip codes rather than broader municipal averages for cities with over 100,000 residents. It directly affects housing developers, affordable housing programs, and government agencies that determine eligibility for low-income housing assistance in large municipalities. By amending multiple state laws, the legislation mandates that income thresholds be proportional to the specific zip code where a housing project or household is located. This change aims to provide a more granular measure of local income levels, ensuring that affordability requirements reflect the economic conditions of individual neighborhoods within large cities.
