EV CHARGER INSTALLATION — CAMBRIDGE
EV Charger Installation In Cambridge, Permitted The Cambridge Way
Cambridge runs its own permitting and inspection process separate from Boston's, which matters for an EV charger circuit as much as the wiring does — and with a housing stock split between older multifamily buildings and newer condo development, whether home charging is even realistic depends heavily on which type of building you're in.
Cambridge Pulls Its Own Permits
Unlike neighboring Boston, Cambridge has its own inspectional services process for electrical permits, and a dedicated circuit for a Level 2 charger needs to go through it — not Boston's. EMC handles that distinction as part of the job, filing with the correct city rather than treating Cambridge as an extension of Boston's process. It's a small administrative detail that matters a lot if it's done wrong, since a permit filed with the wrong department can hold up an inspection and delay the day the charger actually goes live. Filing correctly the first time is an easy mistake to avoid, but only if whoever's doing the work already knows Cambridge runs its own process.
Old Multifamily Buildings And A Heavy Rental Market
Cambridge has a lot of older multifamily housing where the electrical service was installed for a building with several separate tenants, not a single household charging a car overnight. In a rental situation, adding a charger circuit usually means the landlord authorizing the work and, often, deciding how a shared service gets allocated if more than one unit wants charging eventually. That's worth sorting out before an electrician gets involved, not after, since it changes who signs the permit and who pays for what. Even a single building split into a few rental units can run into this question, since the panel behind an older Cambridge multifamily rarely anticipated one tenant charging a car overnight.
Newer Condo Buildings Make It More Direct
Cambridge's newer condo developments tend to have parking built in from the start — attached or underground garages designed with modern electrical loads in mind. That doesn't eliminate the need for a capacity check, but it usually makes for a more straightforward install than retrofitting an older triple-decker or converted multifamily building where the panel was never sized with a charger in mind. Either way, EMC runs the same load calculation before recommending any specific charger. Cambridge's mix of these two very different building types means no two estimates here look quite the same.
ANSWERS
COMMON QUESTIONS
Does Cambridge really use a different permit process than Boston?
Yes — Cambridge has its own inspectional services department, separate from the City of Boston. An electrical permit for a Cambridge address needs to go through Cambridge's process, not Boston's.
I rent in Cambridge — can I get a charger installed?
Only with your landlord's authorization, since the circuit ties into the building's electrical system. That conversation needs to happen before any electrical work starts, especially in an older multifamily building.
Is a newer Cambridge condo building an easier install than an older one?
Generally, yes, since newer buildings are more often designed with adequate electrical capacity and dedicated or garage parking from the start. Older multifamily buildings need a closer look at what the panel can actually support.
