Massachusetts voters will decide on November 3 whether to approve Question 7, a ballot initiative aimed at reforming local zoning laws to facilitate the construction of smaller, more affordable single-family homes. Proponents argue that current zoning regulations, which mandate large minimum lot sizes, have constrained housing supply and contributed to a decline in homeownership among younger residents.

Since the 1980s, many Massachusetts communities have required minimum lot sizes significantly larger than those on which existing smaller homes were built. In Stoughton, for example, the minimum lot size now exceeds three times the size of many older properties, leading to a more than 50 percent decrease in new single-family home construction since 1980. At the same time, the homes built tend to be larger and more expensive, effectively excluding first-time buyers from the market.

Statewide, approximately half of the existing single-family homes would not meet current minimum lot size requirements, amounting to roughly 700,000 residences. These smaller homes historically served as accessible entry points for families purchasing their first homes, a pathway that has increasingly narrowed as municipalities enforce more restrictive zoning standards.

Statistics highlight the impact of these policies. Only 9 percent of new housing units currently qualify as “starter homes,” while the proportion of first-time homebuyers has dropped to a record low of 21 percent in 2025. The median age of first-time buyers has risen to 40, compared with 29 in 1981. The Greater Boston Chamber of Commerce’s recent report found that Massachusetts issued 170 housing permits per 100,000 residents in 2025, less than half the rate of competing states, and noted an exodus of 33,000 residents, many under 35, to states with more affordable housing options.

Question 7 would prohibit cities and towns from requiring minimum lot sizes larger than 5,000 square feet or more than 50 feet of frontage for single-family homes on parcels with access to public water and sewer. Other zoning rules, including setbacks and height limits, would remain under local control. The measure does not apply to rural or undeveloped land.

Backers estimate that passage of Question 7 could lead to the construction of an additional 2,200 to 5,700 homes annually. A recent poll indicated that approximately 63 percent of Massachusetts voters support the initiative. However, the Massachusetts Municipal Association opposes the measure, contending that zoning decisions should remain under local jurisdiction.

Critics caution that stripping zoning authority could undermine local planning priorities, while supporters argue that local control has often been used to exclude working-class families and limit housing diversity. Advocates emphasize that the current zoning landscape acts as a significant barrier to homeownership, contributing to prolonged renting and outmigration among younger residents.

The debate over Question 7 centers on balancing local governance with the need to address Massachusetts’ housing shortage and affordability crisis. With a state goal to add 222,000 new housing units by 2035 to meet demand, voters’ decision will have significant implications for future residential development and the region’s demographic trends.
