Quick answer
Yes. A hardwired Level 2 charger is an installation of electrical wiring and fixtures, which requires the state electrical permit process: under M.G.L. c. 143, s. 3L, 'No person shall install for hire any electrical wiring or fixtures subject to this section without first or within five days after commencing the work giving notice to the inspector of wires,' and 'Said notice shall be given by mailing or delivering a permit application form prepared by the board, to said inspector,' with written notice to the inspector on completion. The work falls under the specialized-code carve-out that 780 CMR 105.2 itself flags (specialized codes of M.G.L. c. 143, s. 96), and the electrician licensing exemptions in M.G.L. c. 141, s. 1A do not include homeowners, so in practice the permit is filed by a licensed electrician with the local inspector of wires.

What ev charger permit costs in Boston
An Electrical Permit is required per Boston's EVSE installation guide, billed under the electrical fee schedule at $20 application fee plus cost-based charges, per the ISD fee schedule effective 5/15/2023.
How to apply in Boston
In most of the US, installing a Level 2 (240 volt) home EV charger is handled as an electrical permit built around a load calculation and a single line diagram showing the new dedicated circuit. A Level 1 charger that simply plugs into an existing 120 volt outlet typically needs no permit unless new wiring is added.
What most ev charger permit applications include:
- A Level 2 charger needs its own dedicated 240 volt circuit and requires an electrical permit with inspection, since each outlet installed for EV charging must be fed by an individual branch circuit with no other outlets on it (NEC 625.40).
- The application includes an electrical load calculation showing the existing service panel has enough spare capacity for the added EVSE demand, worked out using the standard dwelling load calculation method (NEC 220.83).
- The breaker or other overcurrent device feeding the charger must be sized for continuous duty, rated at not less than 125 percent of the equipment's maximum load (NEC 625.41).
- Plan submittal typically includes a single line diagram showing conductor size, breaker size, conduit, and panel rating, plus the charger's manufacturer specifications, since the EVSE itself must be a listed product (NEC 625.5).
- For charging equipment rated over 60 amps or over 150 volts to ground, the application has to show a disconnecting means installed in a readily accessible location and capable of being locked open (NEC 625.43).
- The charger must be shown connected and fastened in place according to the manufacturer's installation instructions, whether it is hardwired or a plug in unit on a dedicated receptacle (NEC 625.44).

Inspections and closing out your permit
A Level 2 EV charger installation gets a rough wiring inspection if any new conductors will be hidden inside walls, ceilings, or run underground, then a final inspection that checks the dedicated circuit, breaker sizing, any required GFCI protection, the disconnect, and the charger's listing before the permit closes.
- If new EVSE conductors will be concealed in a wall or ceiling, or run underground, they must pass a rough wiring inspection before being covered, since that inspection confirms the dedicated branch circuit required for the charger (NEC 625.40).
- At final inspection, the breaker or other overcurrent device serving the charger is checked to confirm it is properly rated for the continuous EV charging load (NEC 625.41).
- Any receptacle installed for EV charging, as opposed to a hardwired connection, has to be checked for ground fault circuit interrupter protection (NEC 625.54).
- Where the EVSE is rated over 60 amps or 150 volts to ground, the inspector confirms a lockable, readily accessible disconnecting means was installed (NEC 625.43).
- The inspector verifies the charger, along with its fittings and associated equipment, carries a nationally recognized testing laboratory listing (NEC 625.5).
- Mounting height is checked against the manufacturer's instructions, with the coupling means generally required to sit at least 18 inches above an indoor floor or 24 inches above outdoor grade unless the equipment is listed otherwise (NEC 625.50).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Boston permit portal or by phone at (617) 635-5300.

- Where do you apply for a ev charger permit in Boston?
- You can apply through the Boston permit portal or contact the Inspectional Services Department directly. The links are listed on this page.
- Can a homeowner pull a ev charger permit themselves in Boston?
- Under Massachusetts law (780 CMR R105.3; 780 CMR 110.R5.1.3.1 (10th ed.); M.G.L. c. 142, s. 3; M.G.L. c. 141, s. 1A): Yes for the building permit itself: 780 CMR R105.3 says 'the owner or authorized agent shall file a permit application.' The construction supervisor license (CSL) rules contain an explicit homeowner exemption at 780 CMR 110.R5.1.3.1: 'Any homeowner performing work for which a building permit is required shall be exempt from the licensing provisions of 780 CMR 110.R5, provided that if a homeowner engages a person(s) for hire to do such work, then such homeowner shall act as supervisor.' 'Homeowner' is defined as a person who owns a parcel on which he or she resides or intends to reside with a one- or two-family dwelling; a person who constructs more than one home in a two-year period does not qualify. The exemption does not extend to the trades: plumbing and gas work requires licensure under M.G.L. c. 142, s. 3, which contains no homeowner exemption, and the electrician licensing exemptions in M.G.L. c. 141, s. 1A likewise do not include homeowners. Confirm how Boston applies this before you apply.
