Massachusetts voters rejected Question 7, a zoning initiative that would have legalized single-family homes on small residential lots.

Margins were narrow, with 50.6% of voters voting “no.” Just 32,322 votes out of the 2.5 million cast made the difference, according to reporting from the Associated Press.

Under the initiative, a new, smaller, category of residential lots would have automatically been zoned for single-family home construction, as long as the lots measured at least one-ninth of an acre, already had access to public sewer and water services and maintained at least 50 feet of land bordering the street.

Proponents touted the question’s potential to increase the Bay State’s supply of affordable housing, while opponents worried it would remove local control of zoning decisions and wouldn’t guarantee the new homes would be affordable.

Andrew Mikula, campaign chair of Yes on 7: Legalize Starter Homes shared his thoughts on the outcome with Boston Agent magazine:

“We’re disappointed that, despite overwhelming evidence that housing affordability and production are priorities for Massachusetts voters, Question 7 will not immediately be among the solutions to our housing challenges … We are grateful for our broad coalition of supporters across the state, and we look forward to continuing to work with them to advocate for meaningful reforms to bring more homeownership opportunities to Massachusetts so all families can realize the American Dream.”
