Massachusetts Voters to Decide on Capping Minimum Lot Sizes to Boost Starter Homes

Question 7 places a cap of 5,000 square feet on minimum lot sizes on the Massachusetts ballot, aiming to increase the supply of starter homes. Advocates, led by Pioneer Institute housing economist Andrew Mikula, say the limit could generate more than 5,000 new units annually, roughly doubling recent single-family construction rates. The measure enjoys backing from Governor Maura Healey and a 2025 poll showing strong voter support, but faces opposition from the Massachusetts Municipal Association, which argues that local officials know best.

The policy would apply only to parcels with existing sewer and water services, focusing development on areas already linked to jobs and transit. Experts cite similar reforms in Maine, Kansas, and Houston as evidence that smaller lot requirements can spur housing growth. If approved, the vote could signal statewide voter appetite for zoning reform and pressure local governments to adopt pro-supply policies.
