Is Watertown in Mass Save?

Yes. Watertown gets its electricity from Eversource, not from a municipal light plant, so homes in Watertown are in the Mass Save program. Its natural gas comes from National Grid (the state's list), also a Mass Save sponsor.

Watertown is not on the state's list of municipal light plants. Mass Save is not statewide: 41 light plants serve all or part of 50 municipalities, and homes on their electric service are outside its electric program (Mass Save in municipal light plant towns).

Rebates and financing for new siding in Watertown

Mass Save doesn't pay for the siding itself: its insulation and windows offers cover insulation, air sealing and windows, and siding is not on the HEAT Loan's list of eligible measures.

The insulation can be covered: after a Home Energy Assessment, Mass Save pays 75 to 100 percent of approved insulation and air sealing in Watertown. Book the assessment before the old siding comes off, while the walls are open.

Do you need a permit for new siding in Watertown?

Plan on one. Residing is not on the Massachusetts building code's list of permit-exempt work, and the Watertown Building Department settles the borderline cases. 80% of Watertown's homes were built before 1980 (Census ACS 2018-2022), and work that disturbs paint in a home built before 1978 has to follow the lead-safe renovation rules.
