What it is

Installing and fixing data and phone cabling in small commercial spaces: running Cat6 cable, mounting wall jacks, terminating patch panels, setting up network racks, and connecting office phone systems. You travel to the customer's site with your tools.

Your first three steps

  1. Check your state's contractor licensing board to see whether low-voltage or telecom work needs a license, and what the limits are
  2. Buy a starter kit (cable tester, punch-down and crimp tools, fish rods, ladder) and get general liability insurance
  3. Contact local IT support firms and property managers and offer to take their small cabling jobs
Who pays

Small offices, medical and dental practices, retail stores, restaurants, property managers and IT support companies that need cabling help.

How it makes money

Per-drop pricing for new cable runs, hourly or flat rates for repairs and troubleshooting, and small monthly support contracts for regular clients.

Skills that help
  • Comfortable with hand tools and ladders
  • Basic networking and phone system knowledge
  • Neat, labeled, tidy work
  • Clear quotes and customer communication
Watch out for
  • Many states and some cities require a low-voltage or specialty contractor license, so check before quoting jobs
  • General liability insurance, and workers' comp once you hire
  • Local building codes and permits, plus fire-rated (plenum) cable and firestopping rules in commercial buildings
  • Safety risks from ladders, ceiling spaces and older buildings that may contain asbestos
  • Irregular work early on, so build repeat clients
