Installing a home EV charger in Massachusetts

New charger wiring falls under the Massachusetts Electrical Code (527 CMR 12.00), which has the town issue an electrical permit on the uniform state application form before the wiring goes in, and the wire inspector looks at it before it is covered. Your town's wire inspector confirms the details. Our permits and inspections guide has the office, phone number and permit page for each town we cover.

Published figures are national, not Massachusetts quotes. Fixr (page updated January 31, 2025) lists a home charger install at $1,000 to $2,500, average $1,200, with a plug-in install at $1,000 to $2,200 and a hardwired one at $850 to $1,800. A panel upgrade, if the panel is full, adds $1,500 to $4,000 by its estimate. The one Massachusetts record: at least 99 Boston one-to-four-family electrical permits issued November 1, 2025 to November 2, 2026 mention an EV charger, and the median value written on them was $2,270, which is what applicants declared, not a quote. The cost page collects them. Aurion prices your house from a photo of your panel.

Ask whether they will check the panel's spare capacity, whether the charger you want qualifies for your utility rebate, who pulls the permit, the licence number, a total in writing including the charger and any panel work, and the warranty. The printable checklist on this page has all ten.

Yes. The U.S. Department of Energy says most EVs come with a portable Level 1 cordset that plugs into a standard outlet, and 8 hours at 120 volts replenishes about 40 miles of range for a mid-size EV. It works best on a dedicated circuit near where you park. Level 2 at 240 volts gives about 25 miles of range per hour.

It depends on your electric company. Eversource's 2026 home charging rebate window closed on November 1, 2026. National Grid's Residential EV Charging Upgrade program takes applications until December 10, 2026, and the work must be complete by then. Light plant towns run their own: Reading (RMLD) up to $750, Wakefield up to $650, Danvers $300, Belmont $100. See the rebates and rates guide.

Both big utilities say so. Eversource says it is awaiting the Department of Public Utilities' approval of its 2027 program and that modifications to structure and incentives are expected. National Grid says its incentives are expected to change in 2027. Neither has published 2027 amounts, so we do not show any.

Not for new installs. The IRS says the 30C credit covers property placed in service at your main home through June 30, 2026, at 30% of the cost up to $1,000 per item. A charger placed in service after that date does not qualify.

Not always. The Department of Energy says a qualified electrician can tell you whether your home has the electrical capacity, and that some homes might not. A charger that draws 30 amps needs a dedicated 40 amp circuit. A load management charger can limit its own draw so the panel does not need to grow. See Level 2, amps and your panel and our panel upgrade guide.

Not by prohibiting it or unreasonably restricting it. Under the 2024 climate law (Chapter 239 of the Acts of 2024), M.G.L. c. 183A section 10A bars condominium and homeowners' associations from doing that for a charger at your own parking space, with reasonable restrictions allowed. If the board does not deny your application in writing within 60 days, it is deemed approved. Details on the condos and renters page.

The state law protects owners, so a tenant needs the landlord's agreement. National Grid's program accepts tenants and landlords of 2 to 4 unit buildings and offers a higher wiring rebate for them, up to $1,400. Eversource has a shared-charger tier too. Read the renter steps.

For Eversource, yes: a Wi-Fi compatible Level 2 smart charger, 80 amps or less, on its Qualified Product List. National Grid wants you enrolled in its Off-Peak Charging Program through your vehicle or a listed charger. RMLD wants a Level 2 network-enabled charger. See choosing a charger.

Your electric bill names it. In the table above, Boston, Cambridge, Somerville, Arlington, Watertown, Waltham, Woburn, Winchester, Lexington and Stoneham are Eversource. Melrose, Malden, Everett, Revere, Lynn, Salem and Beverly are National Grid. Belmont, Reading, Wakefield, Peabody and Danvers have their own light plant. Medford can be either, by street.

Eversource says customers who install after November 1, 2026 may be eligible to apply for rebates if the program is available in 2027, but amounts will change and nothing is set. National Grid's 2026 rebate needs the work done and the application in by December 10, 2026. If you want a 2026 rebate in a National Grid town, the schedule is short.

Aurion takes the project from the panel check through the permit and the final inspection. Licensed work is done by licensed Massachusetts technicians. Send a photo of your panel and your town, or call (781) 210-8400.
