What to know about structured cabling in Phoenix
Phoenix's building code covers wiring inside a building
The code states that communications wiring run inside a building is regulated by it. Only utility-controlled communications equipment in dedicated spaces is excluded. Cabling on a tenant improvement is not a free-for-all, so we ask plan review how your job is handled.

Most low-voltage circuits skip the electrical permit
Phoenix exempts Class 2 and Class 3 control and signal circuits from electrical permits unless they are essential for life safety. Whether a given data run qualifies depends on how it's classified. Anything tied to fire alarm or life safety is treated differently, and we flag it up front.

2024 codes apply to plans submitted after 2025
The 2024 Phoenix Building Construction Code took effect August 1, 2025. Every plan submitted after December 31, 2025 must meet it.
Building work near homes has set hours
Building work within 500 feet of an inhabited structure is limited to set hours, and Planning & Development can permit other hours. In winter, October 1 to April 30, work runs 7 a.m. to 7 p.m. on weekdays that aren't holidays. Summer hours run 6 a.m. to 7 p.m. Drilling and other noisy work get scheduled to fit.
What structured cabling includes
Structured cabling is a plan, not a pile of wires. Every outlet, camera and access point gets its own cable back to one place, usually a rack or wall cabinet. The cables end at a patch panel there, and a switch connects them to the network.
That layout lets you move a desk, add a TV or swap a switch without pulling new wire, and each numbered port helps you find a problem fast.
Cat6, Cat6A and fiber
Cat6 handles gigabit speeds and short 10-gigabit runs, and it's the usual choice for desks, phones and cameras. Cat6A holds 10 gigabit across a full 100-meter run and suits new builds and WiFi access points that will be upgraded. Fiber carries data between floors, buildings and racks; see our fiber optic installation page.
- Plenum-rated cable above ceilings that carry air, as the code calls for.
- Shielded cable near heavy electrical loads or kitchen equipment.
- Outdoor-rated cable on patios, roofs and between buildings.
- Extra drops in the walls now, since opening them later costs more than the cable.
Phoenix building types
Phoenix has older masonry buildings, strip centers, high-rise offices and tilt-up warehouses. Block walls and concrete need core drilling or surface raceway. Warehouses may have 30-foot ceilings, so lifts and cable trays get planned early.
On a tenant improvement, plan review may want to see the low-voltage scope. Planning & Development takes commercial permit questions at 602-495-5411, and we help you answer what they ask.
Labeling, testing and documentation
Every cable gets a label at both ends matching the patch panel and a floor plan. We test each run and hand you the results. A cable that fails gets redone. With a clean rack and a map, the next technician, whoever it is, finds things in minutes.
Job sequence
- Walk the closet, ceilings and wall types.
- Draw drop locations, cable types and the rack layout.
- Rough in, then terminate, label and test.
- Schedule work after hours or on slow days so you stay open.
- Service continues Monday to Friday, 8 AM to 5 PM.
Often paired with
Cabling is the base for business WiFi, security cameras and business phone systems. More of what we do in Phoenix is on the Enzo in Phoenix page.
