Building rules come first
In New York the building sets the terms before any cable is pulled. These are the items we settle with property management before the first visit.
Certificate of insurance
Managed buildings ask for a certificate naming the owner and managing agent, often with umbrella coverage and a waiver of subrogation, before anyone gets riser or telecom room access. We send it with the access request.
After-hours work
Core drilling and noisy work usually run in the evening under building rules. Where a job holds a DOB permit, work before 7 a.m., after 6 p.m. or on weekends also needs an after-hours variance.
Asbestos before drilling
When work that needs a DOB permit disturbs building materials in a building from before April 1, 1987, a certified asbestos investigator assesses it first and files the result with DEP.
Firestopping
Every new opening through a rated wall or floor is sealed with a tested firestop system rated at least as high as the assembly, as the NYC Building Code requires, and recorded in the closeout.
Labor rules
Some buildings set their own labor requirements for contractors. We confirm them at the walkthrough so the crew plan and the price match the building.
Across the metro
Two states, very different buildings. The district usually tells us what the job will involve.
New York
Midtown and Hudson Yards. Office towers and new Class A floors, where most jobs are tenant fit-outs on a fixed move-in date.
Lower Manhattan. Finance and government offices, plus the carrier hotels at 60 Hudson Street and 32 Avenue of the Americas, where dozens of networks interconnect.
Long Island City and Brooklyn. Converted industrial buildings and newer office space, where pathways often have to be built from scratch.
Long Island and Westchester. Office parks, medical buildings and retail, often with several sites under one owner.
New Jersey
Jersey City waterfront. The busiest office market in northern New Jersey, with financial firms and back offices across the river from Lower Manhattan.
Newark. Corporate offices, the carrier hotel at 165 Halsey Street, and logistics around the airport and port.
Secaucus and the Meadowlands. Trading data centers, including the Equinix campus where exchanges run matching engines, plus warehouses along the Turnpike.
Licensing on both sides of the Hudson
New York and New Jersey regulate low-voltage work differently, and some suburbs add their own rules.
| Work | New York | New Jersey |
|---|---|---|
| Data and voice cabling | In NYC, wiring under 50 volts generally needs no DOB electrical permit unless it ties into life-safety systems or switches power. | An electrical contractor license, or the Limited Telecommunications Wiring Exemption for voice and data work. |
| Cameras, access control and alarms | Companies that install intrusion or fire alarm systems are licensed by the NYS Department of State. | Licensed through the state Fire Alarm, Burglar Alarm and Locksmith committee, which also covers low-voltage CCTV. |
| Fire alarm | FDNY approves the plans, and the work is done by licensed electricians or FDNY-recognized companies. | Licensed under the same Fire Alarm, Burglar Alarm and Locksmith committee. |
| Line-voltage power | A DOB-licensed master electrician, a permit and a DOB inspection, even for small jobs. | A licensed electrical contractor holding a business permit. |
Leasing drives the work. CBRE counted 7.1 million square feet of Manhattan office leasing in the third quarter of 2026. Most new leases start with a fit-out, and the cabling plan is easiest to get right before the ceilings close.

Common questions
Do you work in all five boroughs and New Jersey?
Yes. We work across Manhattan, Brooklyn, Queens, the Bronx and Staten Island, on Long Island and in Westchester, and in northern New Jersey from Jersey City and Newark to the Meadowlands.
Who handles building approvals and insurance certificates?
We do. We send the certificate of insurance, the scope and the schedule to property management and confirm access, elevator and after-hours rules before the job starts.
Can you work in an occupied office?
Yes. We phase the work floor by floor or zone by zone, keep the noisy work after hours, and cut over each area when your IT team is ready.
Do you install fiber to carrier hotels?
We install fiber inside your building and between your floors and rooms. Cross connects inside a carrier hotel or colocation site are ordered through that facility, and we coordinate the handoff.
