Massachusetts licenses low-voltage systems work
Massachusetts licenses both the companies and the individual technicians who install security and fire alarm systems.
| License or rule | What it covers |
|---|---|
| Systems Contractor (Class C) | The business license for fire warning and security systems, which include access control, video surveillance and intrusion detection. |
| Systems Technician (Class D) | The individual license for doing that work, with no more than one apprentice per licensed technician on the job. |
| S-License | A state license for security businesses. Every employee also needs a Certificate of Clearance with a background check, renewed every two years. |
| Telephone, cable TV and computer systems | Exempt from electrical licensing when installed by a firm primarily in the telecommunications or information systems industry, under Chapter 141, Section 7. |
| Line-voltage power | Master and journeyman electricians only. |
Permits and inspections
The rules changed in 2026, and Boston files everything online.
2026 electrical code
The Massachusetts Electrical Code moved to the 2026 National Electrical Code on April 24, 2026, with state amendments.
City of Boston permits
Inspectional Services issues electrical permits online in the licensed contractor’s name, and work has to start within six months of issue.
Fire alarm
Fire alarm permits go through Boston’s fire alarm permit process with the Boston Fire Department, and the city recommends a fire protection engineer for the design.
Inspection before cover
Cable and devices are inspected before ceilings and walls are closed, so we schedule inspections into the job, not after it.
Labs, hospitals and towers
Greater Boston’s work is concentrated in a handful of dense districts.
Kendall Square, Cambridge
More than 200 life sciences and tech organizations, including 17 of the world’s 20 largest life sciences companies.
Seaport and the Innovation District
Offices and labs on the South Boston waterfront, including Vertex’s headquarters at Fan Pier.
Financial District and Back Bay
Downtown towers and Back Bay offices, including 200 Clarendon, New England’s tallest building.
Longwood Medical and Academic Area
Beth Israel Deaconess, Brigham and Women’s and Boston Children’s hospitals, with research buildings around them.
Route 128
Suburban offices and labs in Burlington, Waltham and Lexington along the region’s original technology highway.
One Summer Street
Markley’s carrier hotel downtown, where about 90 networks interconnect.
Labs change hands often. CBRE put Greater Boston lab vacancy at 28.9% in the third quarter of 2026. Every lab or office that changes tenant needs its network, cameras and access control reworked for the new occupant.
Common questions
Does data cabling need a licensed electrician in Massachusetts?
Telephone, cable TV and computer system work is exempt when done by a firm primarily in the telecommunications or information systems industry. Security, access control, camera and fire alarm work needs licensed systems technicians. We confirm with the local inspector which rules apply to your job.
Can you work in labs and hospitals?
Yes. We follow the facility’s access, infection control and lab safety rules, schedule work around research and patient areas, and keep instrument networks separate where the lab needs it.
Do you work in southern New Hampshire?
Yes, in the towns that are part of the Boston metro. New Hampshire licenses electrical work for heat, light or power at any voltage, and we check each town’s permit rules.
Can you install outdoor cameras in winter?
Yes. Boston’s January lows average about 23°F and the city sees about 49 inches of snow a year, so we specify cold-rated cameras and housings and mount them clear of snow and ice.
