Structured Cabling Permit Requirements in Charlotte, North Carolina

Quick Answer: Mecklenburg County requires electrical permits for structured cabling installations involving low-voltage wiring. While some systems may be exempt from contractor licensing requirements, permits and inspections are still required per NC General Statute. Installers should hold a North Carolina SP-FA/LV or SP-LV electrical license, and all work must comply with NEC Article 800 for communications circuits.

When Are Permits Required?

Mecklenburg County Code Enforcement requires permits for most structured cabling installations:

Permits Required

• Low-voltage system installation: Data cabling, network infrastructure, telecommunications
• Commercial installations: All business structured cabling projects
• New construction: Data cabling as part of building projects
• Riser installations: Vertical cable runs through multiple floors
• Pathway installations: New conduit, cable trays, or fire-rated penetrations

Permit Exemption Conditions

Some low-voltage systems may be exempt from licensed contractor requirements (but still require permits) if ALL conditions are met:

• System is not required by NC State Building Code
• Control circuit is Class II or Class III per NEC
• Operates at 50 volts or less
• Not installed in hazardous areas per NEC
• Protected by circuit breaker, fuse, or current limiting device

North Carolina Contractor Licensing Requirements

Structured cabling installation in Charlotte requires proper licensing from the NC State Board of Examiners of Electrical Contractors:

Electrical Contractor License Options

License Type	Designation	Structured Cabling Coverage
SP-FA/LV (Fire Alarm/Low Voltage)	Special Restricted	Low voltage wiring including data cabling
SP-LV (Low Voltage)	Special Restricted	Low voltage systems including telecommunications
Limited/Intermediate/Unlimited	General	Full electrical including low voltage

Industry Certifications

While not legally required, professional certifications demonstrate competency:

• BICSI RCDD: Registered Communications Distribution Designer
• BICSI Technician: Installation technician certification
• Manufacturer certifications: Panduit, Commscope, Belden for warranty compliance

NEC Article 800 Compliance Requirements

North Carolina enforces the National Electrical Code for all communications circuit installations. Key Article 800 requirements include:

Cable Ratings by Location

• CMP (Plenum): Required in air-handling spaces above ceilings and under raised floors
• CMR (Riser): Required for vertical runs between floors
• CM (General): Acceptable for general-purpose horizontal runs

Installation Standards

• Workmanship: Equipment and cabling must be installed in a neat and workmanlike manner
• Support: Cables must be secured with straps, staples, cable ties, or hangers
• Separation: Maintain 2-inch separation from power conductors or use proper barriers
• Fire stopping: Seal all penetrations through fire-rated assemblies

Abandoned Cable Requirements

Remove accessible portions of communications cables that do not terminate at equipment and are not tagged for future use. This limits combustible materials in buildings.

Grounding Requirements

Communications system grounding must comply with NEC 250.70. If installing a separate grounding electrode, bond it to the building's power grounding system with minimum 6 AWG conductor.

Mecklenburg County Permit Application Process

Step 1: Set Up Account

Create an account on the Mecklenburg County Citizen Access Portal.

Step 2: Submit Electrical Permit Application

If multiple contractors install different low-voltage systems, each contractor needs a separate permit application. Coordinate with overall project permits for new construction.

Step 3: Plan Review

For commercial projects, submit plans showing:

• Cable pathway layouts and riser diagrams
• Telecommunications room locations
• Fire stopping details for penetrations
• Equipment specifications

Average review turnaround:

• Under 10,000 sf: Approximately 10 business days
• Larger projects: Approximately 15 business days

Step 4: Inspections

Projects requiring permits typically need three inspections:

• Rough-in inspection: Before walls are closed
• Service inspection: Electrical verification
• Final inspection: Complete system verification

• Installing network outlets and patch panels
• Home theater and distributed audio wiring
• Smart home device networking

Note: Permits are still required even if contractor licensing is exempt.

• Licensed contractor required: SP-FA/LV, SP-LV, or higher electrical license
• Permits mandatory: No exemptions for commercial properties
• ANSI/TIA/EIA standards: Compliance with industry cabling standards
• Fire code compliance: Plenum-rated cable in air handling spaces

Industry Standards Compliance

Charlotte structured cabling installations should comply with:

• ANSI/TIA-568: Commercial building telecommunications cabling standard
• ANSI/TIA-569: Telecommunications pathways and spaces
• ANSI/TIA-606: Administration standard for telecommunications infrastructure
• NEC Article 800: Communications circuits requirements
• NEC Article 725: Class 2 and Class 3 remote-control circuits

Pro Tips from Contractors

• Separate permits: If different contractors handle different low-voltage systems, each needs their own permit application
• BICSI certification: RCDD or Technician credentials demonstrate professionalism and may help with commercial bids
• Manufacturer training: Certifications from Panduit, Commscope, or Belden may be required for extended warranties
• Fire stopping documentation: Document all firestop installations with photos and material specifications
• Cable testing: Provide test results and certification documentation for commercial clients
• Abandoned cable removal: Remove or properly tag cables per NEC requirements
