Massachusetts is facing a growing housing affordability crisis that is affecting both young adults seeking starter homes and older residents looking to downsize. Between May 2019 and May 2026, the number of active home listings in the state declined by more than one-third, while the median home value increased by 50 percent, reaching $697,000 for a detached single-family residence as of May 2026. These trends have contributed to significant demographic shifts, with the state adding nearly 75,000 households headed by those under 35 between 2016 and 2022, while simultaneously losing 33,000 residents to other states between July 2024 and July 2025, many of whom are young adults priced out of the market.

Experts attribute part of the state’s housing challenges to a persistent shortage of small, affordable homes traditionally known as starter homes. In recent decades, the construction of such homes has sharply declined nationwide—from 24 percent of new single-family homes having two or fewer bedrooms in 1984 to just 5 percent in 2025. Massachusetts has also seen the net loss of approximately 8,000 small single-family homes since 2010, as many are demolished and replaced with larger, more expensive houses.

Local zoning laws and building regulations are cited as key obstacles that limit the development of starter homes. Large minimum lot sizes and restrictions on home typologies compel builders to focus on larger, detached single-family homes to cover rising land and construction costs. A homebuilder based in Beverly, Massachusetts, noted that no local municipality currently incentivizes the industry to build smaller, more affordable houses. Meanwhile, a 70-year-old resident of Wellesley expressed challenges in finding downsized housing options due to prohibitive costs and lengthy waiting lists for retirement community apartments.

Efforts to address the shortage have included the state’s legalization of accessory dwelling units (ADUs) in 2024, allowing smaller homes on the same lot as larger primary residences. However, experts recommend that local governments further relax zoning restrictions to permit more townhouses, condominiums, and smaller homes on smaller lots to increase supply and reduce costs. Currently, the median lot size for newly sold single-family homes in Massachusetts far exceeds that in other regions, with most municipalities setting minimum lot sizes around 10,000 square feet—nearly twice the size typically seen elsewhere in the United States.

The median prices for townhouses and condominiums in Massachusetts remain lower than detached homes—about $548,000 and $587,000 respectively—but many communities require discretionary review processes that hinder development. Advocates stress the need for streamlined regulations to promote more diverse and affordable housing options.

Without comprehensive reforms, Massachusetts risks continued out-migration of young families and retains older homeowners in houses ill-suited to their needs. Housing economist Andrew B. Mikula of the Pioneer Institute warns that without increased entry-level home construction, the state’s economic growth and familial stability could be jeopardized. The case of Massachusetts highlights the broader challenges confronting states across the country as demand outpaces the supply of affordable housing, underscoring the importance of regulatory changes aimed at supporting diverse housing types for a changing population.
