Question 7 would set a statewide minimum lot size of 5,000 square feet for single-family homes in communities with public water and sewer (CommonWealth Beacon). That is just over one-tenth of an acre. If it passes, it may change what your land is worth and what a starter home could cost in your town (WBUR).
Supporters say smaller lots could mean cheaper starter homes in a state that needs about 222,000 more homes by 2035, according to a 2026 CommonWealth Beacon report. Massachusetts prices rose faster than any other state's since 1980, and the median single-family price jumped 10 percent between 2023 and 2024, to $610,000 (CommonWealth Beacon). Governor Maura Healey backs the measure. Local officials quoted in WBUR oppose it, saying towns should set their own zoning rules.
What would change?
Today, each town sets its own minimum lot size. Question 7 would set a statewide floor of 5,000 square feet for any lot with public water and sewer, plus at least 50 feet of street frontage. That is a big step down for many places. For more than half of the properties zoned for single-family homes, current rules require about an acre or more, and about a quarter need two acres (WBUR). It would not apply to Boston. Towns could still set limits on height, parking, and open space (WBUR). Statewide, about 850,000 parcels fall under the new rules, though most already allow some building; only about 200,000 would immediately open to new construction (MassLive).
What does it mean for homeowners?
An owner with a large, sewer-served lot could split it into smaller buildable lots, according to the WBUR analysis of the measure. That new option may raise what the land is worth, even if you never build, because a parcel that can hold more homes is more valuable. For buyers, more small lots could mean more affordable entry-level homes, though a smaller lot is not automatically a cheaper home, since builders still pass land costs and construction prices into the asking price (MassLive).
What does it mean for housing?
The Tufts Center for State Policy Analysis projects about 750 new homes a year, from 350 to 1,200 (Tufts Now). That would lift single-family home construction by about 15% and overall housing production by about 5% (MassLive). Against the state's need for more homes, it is a modest start.
What should you do now?
If you own a large, sewer-served lot, find out what your parcel could become under the new rules before you vote or sell. An analysis finds the change would help most in suburbs with robust sewer systems and lots that are large enough to split (Provincetown Independent). To understand how your own town might be affected, look up its current minimum lot size online before you vote. If you are planning to buy, refinance, or sell, talk to a loan officer about how a smaller lot could affect how a lender values the property and what financing options may be available. The measure is on the November ballot.

Frequently Asked Questions
1Does the 5,000 square foot rule require both public water and public sewer, or only one?
Both. The cap applies to a lot that has public water and public sewer service ([CommonWealth Beacon](https://commonwealthbeacon.org/ballot-question/2026-question-7-starter-homes)). If a town has only one of the two, or neither, the 5,000 square foot floor does not apply there.
2Which towns would the change actually affect?
Towns that have both public water and sewer on the lot, and where the current minimum lot size is larger than 5,000 square feet. A town that already allows smaller lots would not see any change, and communities without public water or sewer would be unaffected ([WBUR](https://www.wbur.org/news/2026/10/07/massachusetts-election-ballot-question-7-starter-homes-small-lots)).
3If the measure passes, when would the new lot size rule take effect?
Roughly a month after the election, if voters approve it ([CommonWealth Beacon](https://commonwealthbeacon.org/ballot-question/2026-question-7-starter-homes)). The state's Executive Office of Housing and Livable Communities would then be responsible for writing and enforcing the rules for how it applies.
