Before you hire in Cambridge
A short checklist of things to verify before you sign a contract or hand over a deposit. These apply whether you find your contractor here, on Angi, or anywhere else.
- 1
Building permit on the contractor, not you
Most cities require a permit for any structural work. The contractor should pull the permit in their name so they carry the liability for code compliance. If a contractor offers to skip the permit or asks you to pull it as a homeowner, that is a warning sign. - 2
Licensed electrician
Most states require a state-issued electrical license. Always ask for the license number, confirm it matches the person doing the work (not just the business owner), and check it against the issuing board's online lookup. - 3
General liability + workers comp
Ask for a Certificate of Insurance (COI) with you listed as a certificate holder, before any work begins. Without workers comp, an injured worker can sue the homeowner directly. $500K–$1M general liability is standard. - 4
Written contract with clear terms
Get it in writing. The contract should cover: scope of work, total price (not hourly unless explicitly agreed), materials and brands, start and finish dates, payment schedule tied to milestones (not calendar dates), warranty period, and procedures for change orders. Never pay more than 1/3 up front, and never pay the final payment until the work passes inspection. - 5
References and public reputation
Ask for 3 references on recent similar projects and actually call them. Cross-check reviews across Google, the Better Business Bureau, and the state licensing board's complaint history. A contractor with zero online footprint is a risk, even if they come highly recommended.
Every contractor we list is verified against public records, but verification is not a quality guarantee. Run through this checklist on any contractor you are seriously considering.
How to Choose a Electrician in Cambridge
Follow these steps to find a reliable, licensed electrician in the Cambridge, Massachusetts area.
Verify the master electrician license
Any permitted electrical work must be signed off by a licensed master electrician. Look up the license on your state electrical board before hiring.
Confirm liability insurance and bonding
Electricians should carry at least $1M general liability plus workers compensation. Bonded contractors give you recourse if work fails inspection.
Require permits on every job
Panel upgrades, new circuits, EV chargers, and rewires all need a permit. A licensed electrician pulls the permit — not you. Cash deals without permits void your insurance.
Get 3+ written bids for big work
Panel upgrades and rewires should have itemized bids. Watch for "too good to be true" pricing, which often signals unlicensed labor or corner-cutting on conductors.
Ask about EV charger certification
For Level 2 installs, ask if the electrician is familiar with your panel brand and local utility requirements. Some utilities require load management gear.
Demand a written warranty
Quality electrical work comes with a 1-year workmanship warranty at minimum. Equipment manufacturer warranties (panels, chargers) run 5-25 years separately.

How much does it cost to install a Level 2 EV charger in Cambridge?

Longer runs, trenching to a detached garage, panel upgrades, or load management gear push costs higher. The federal Section 30C credit (30% up to $1,000) is still available through June 30, 2026 for residential installs in qualifying census tracts — ask your electrician to confirm eligibility before the deadline.
Do I need a permit to hire an electrician in Cambridge?
Yes. Nearly all electrical work in Cambridge requires a permit — panel upgrades, new circuits, outlet additions, EV chargers, generator transfer switches, and whole-house rewires. Permit fees typically range $77-$448 and your licensed electrician should pull the permit (not you). Simple fixture swaps on existing circuits are the main exemption. Work without a permit is a code violation that can void your homeowners insurance and block a future home sale.
How do I verify an electrician is licensed in Massachusetts?
Most states publish a searchable licensing roster you can use to confirm an electrician's license status, bond, and disciplinary history. In Massachusetts, look up the state electrical board (or department of labor) online license lookup before hiring. Ask to see the license card, confirm the license number matches public records, and require proof of liability insurance and workers comp (never pay cash without these verified).
What is a master electrician vs a journeyman?
A master electrician has passed an advanced exam (typically requiring 7,000+ hours of field work plus written and practical tests) and can pull permits, sign off on work, and supervise journeymen and apprentices. A journeyman electrician has completed a 4-year apprenticeship and can do most wiring work under a master's license. For any job requiring a permit in Cambridge, a master electrician must be on the license — confirm this before signing a contract.
Is Cambridge stricter than Boston on energy code?
Cambridge adopted the Specialized Opt-in Stretch Code in 2023, which means new construction in Cambridge faces higher energy performance targets than the statewide base code, similar to but separate from Boston.
What triggers Cambridge Historical Commission review?
Exterior changes, demolitions, and new construction in a local historic district or on a designated landmark property all trigger review. Interior work is usually exempt unless it affects protected interior features.
