Mylarith QynthorilTL;DR: Run network cable while the studs are still exposed, because adding it after drywall means opening finished walls. Give every camera, access point, display and smart device a dedicated wired line back to one central point, and leave empty pathways for whatever you add later. Bring in a low voltage specialist before insulation goes up, not after paint.
If your renovation will have smart devices, run the network cabling during rough-in, before insulation and drywall. Once the walls are closed, every new cable is a patching job. Open walls are the cheapest moment you will ever get to wire a home properly.
What Is Structured Cabling?
Structured cabling is a planned, organized wiring system that connects every network device in a building back to one central location, using standardized cable, labeled terminations and defined pathways. Instead of a tangle of cords run ad hoc to wherever a router happens to sit, each outlet has its own dedicated line to a single patch point.
For a renovation, that means the network is built into the structure the same way plumbing and electrical are. Planning network wiring nyc projects starts with where devices will live, not where the router sits today. In dense city buildings that question is harder than it looks, because walls, risers and shared shafts limit where cable can travel.
Why It Matters More During a Renovation
Wireless handles a lot, but it is only as good as the wired connection feeding it. Ceiling access points, cameras, video intercoms and wall-mounted displays all perform better, and fail less mysteriously, on a dedicated cable than on a wireless hop.
The point most renovation guides skip is that the pathway matters more than the cable. Cable standards change and cable ages, but a conduit or an accessible route lets you pull a replacement without touching a wall. A contractor who runs cable but leaves no way to run more has solved today’s problem and created tomorrow’s.

How It Works
Home runs, not daisy chains
Each drop gets its own cable back to the central rack or panel. Daisy-chaining one outlet off another saves cable and costs you every time something in the chain fails, because one fault takes out several rooms and the culprit is hidden inside a wall.
Pathways and separation
Low-voltage cable should be kept apart from line-voltage electrical runs where they cross or run parallel, since close parallel runs invite interference. Plan the crossing points with the electrician at rough-in, not after their boxes are set. Leave pull strings or conduit in any run that would be painful to reopen, such as a ceiling over a finished stairwell.
Termination, testing and labeling
Every cable should be terminated cleanly, tested end to end, and labeled at both ends before it disappears behind a wall. A cable that tests fine today and is labeled with a room name is worth far more than an unlabeled bundle in a closet. Test before the drywall crew arrives: a failed run found afterward costs you a wall.
The Practical Order of Operations
A low voltage contractor in NYC can handle the cabling alongside intercom, camera and access control wiring so those systems share one coherent plan instead of three separate ones. The earlier that conversation happens, the fewer walls get revisited.
Common Mistakes
- Treating the router location as the plan. Devices should dictate cable routes; the router location is only the starting guess.
- Running cable but no pathway. The first upgrade then means opening a wall.
- Skipping labels. Troubleshooting a closet of identical unlabeled cables is slow and error-prone.
- Installing wireless-only smart devices, then closing walls. If a device later needs a wired connection or power over the cable, you have no route to it.
- Letting each trade work alone. Electrical and low-voltage crews need to agree on crossings before the boxes are fixed.
FAQ
When is the best time to run network cable in a renovation?
During rough-in, after framing and electrical boxes are set but before insulation and drywall. Walls are open, access is easy, and you can test every run before anything is covered.
Is Wi-Fi enough, or do I still need wired cabling?
Wi-Fi works best when its access points are fed by a wired connection. Cameras, displays and fixed devices also tend to be more reliable on a dedicated cable than on a wireless link.
What is the difference between a home run and a daisy chain?
A home run gives each outlet its own cable back to the central point. A daisy chain links outlets in series, so a single fault can cut off several rooms at once.
Can I add network cable after the walls are finished?
Yes, but it usually means opening walls, fishing around obstructions and patching afterward. In older buildings with tight cavities and shared shafts, the work is slower and more disruptive.
Should low-voltage and electrical wiring be run together?
Keep them separated where possible and plan any crossings with the electrician. Close parallel runs can cause interference, so agree on routes before electrical boxes are fixed.
Before You Close the Walls
The decision that pays off is the unglamorous one: before drywall, write down every device you might want in five years, and make sure each location has a cable or an empty pathway to it. Then have the runs tested and labeled while you can still see them.
