A surge of housing development in a Boston suburb is providing evidence that natural-gas bans and strict energy-efficiency standards do not slow new construction or make it more expensive. Indeed, these guidelines can even boost the growth of affordable housing, say local advocates.
In 2024, Lexington, Massachusetts, banned gas hookups in new construction and adopted a stringent building code that requires high energy-efficiency performance. Yet these regulations have not stopped the town of roughly 34,000 from permitting some 1,100 new units of housing—160 of which will be affordable—over the past two years.
“Opponents said, ‘It’s going to cost so much, you’re going to stop the development of affordable housing.’ But that clearly wasn’t the case,” said Mark Sandeen, a member of the town select board and the board of the Lexington Affordable Housing Trust.
As Massachusetts aims to get to net-zero carbon emissions by 2050, the state has for several years prioritized policies that encourage the transition away from fossil fuels, particularly natural gas, which heats about half of the state’s homes. In 2022, Massachusetts launched a pilot program allowing 10 communities—including Lexington—to prohibit the use of fossil fuels in new construction and major renovations. In late 2023, utilities regulators issued an order that makes explicit the state’s goal of getting off natural gas, and lays out strategies and principles for reaching this goal.
Detractors, however, have consistently argued that requiring or even heavily encouraging all-electric construction would make housing more costly and difficult to build at a time when Massachusetts is facing an acute housing shortage. In 2022, then-Gov. Charlie Baker, a Republican, memorably said the idea of fossil fuel bans gave him “agita,” so worried was he that such municipal regulations would suppress housing growth.
Similar battles have played out across the country, from California to New York.
There is plenty of evidence that electrified, highly efficient homes don’t need to come with a price premium.
