Northampton adopts fossil-fuel‑free construction ordinance to join state demonstration program

Northampton — The City Council on Jan. 16 approved an ordinance that allows the city to participate in the Massachusetts Fossil Fuel Free Demonstration Program, a state pilot that encourages new construction and major renovations to avoid fossil‑fuel heating systems.

The ordinance drew broad public comment during the meeting and was amended before the council’s unanimous approval to add specific exemptions and clarifications requested by residents, building professionals and state agencies.

Supporters told the council the ordinance would push builders and owners toward heat pumps and other electric systems while keeping limited exemptions for defined circumstances. “It is very reasonable and very well thought out,” said Bill Diamond of Northampton, who urged approval and said the change would “help people in Northampton to live in healthier buildings and pay less money for heating their homes.”

Why it matters: Northampton was chosen by the state as one of the communities invited to the demonstration program, and joining is a prerequisite for federal and state pilot data collection under the program. Adopting the ordinance makes the city eligible to provide implementation data to the Department of Energy Resources and helps the city align local policy with state decarbonization goals.

What changed: After a legislative‑matters hearing and follow‑up meetings, sponsors inserted clarifying language to address concerns raised in public testimony. Major edits included: - Clarifying that the ordinance applies to new construction and to “major renovation” when defined by the building code, so routine repairs are excluded; - Allowing emergency or standby generators for residential use in disaster or other force‑majeure circumstances; - Limiting some commercial exemptions (for example, certain indoor/outdoor commercial cooking appliances) to commercial uses and requiring readiness for electric replacements and required ventilation and electric service capacity when fossil fuel systems are used; - Treating buildings connected to a district thermal network (for example, a campus geothermal or central plant) so that up to 20% of design heating load may be supplied by fossil fuel if the larger system reduces net fossil‑fuel use.

Those edits emerged after consultations with city staff, state model language and building‑industry representatives. “We made changes recommended by DOER and local builders to provide flexibility while keeping the ordinance consistent with the pilot’s goals,” Councilor Rachel Maiori said during debate.

Opponents and concerns: Some residents and builders raised affordability and implementation concerns for large renovation projects, asking for clearer exemptions and more time for community outreach. Councilors and staff repeatedly said the ordinance does not require owners to retrofit working fossil‑fuel systems; it applies to the defined triggers (new construction and major renovation) and includes the exemptions adopted at the meeting.

Votes and next steps: The council voted to adopt the ordinance as amended. The city will now submit the required documentation to the state to participate in the demonstration project and will continue discussions about administrative implementation and building‑department procedures.

Ending: Sponsors said the ordinance is intended to be a living tool that the city can tweak after pilot data and local experience. Council President Alex Jarrett thanked staff and residents for the public engagement that led to the final language.
