Structured Cabling Permit Requirements in Travis County, Texas

Quick Answer: Structured cabling in Travis County is exempt from state electrician licensing under Texas law, but local permit requirements vary by location. Austin requires electrical permits for low voltage installations. Unincorporated Travis County has different requirements handled through the Transportation and Natural Resources (TNR) Development Services. Always verify your jurisdiction before starting work.

Understanding Travis County Jurisdiction

Travis County includes Austin and surrounding communities. Permit requirements differ based on location:

• City of Austin – Electrical permits required for low voltage work
• Unincorporated Travis County – Permits through TNR Development Services
• Other municipalities – Contact local building department

Use the Travis County Jurisdiction Web Map to verify which city and county your property is located in before starting any project.

Texas State Exemptions for Structured Cabling

The Texas Department of Licensing and Regulation (TDLR) provides exemptions for low voltage work. Under the Texas Electrical Safety and Licensing Act (Section 1305.003), the following are NOT subject to electrician licensing:

• Class 1, Class 2, or Class 3 remote control circuits
• Signaling or power-limited circuits
• Fire alarm circuits
• Optical fiber cables
• Communications circuits, including raceways
• Equipment provided by cable operators or telecommunications providers

This means structured cabling installers—working on Cat5e, Cat6, Cat6a, fiber optic, and other data cables—are not required to hold a state electrician license in Texas.

Important: Municipal regulations can override state exemptions. Austin specifically requires electrical permits for low voltage installations.

For complete details on Texas licensing, see our Texas Low Voltage License Guide.

Residential Structured Cabling

Most residential structured cabling in Travis County does not require permits if:

• Work is limited to low voltage (under 50V)

Common residential projects include:

Commercial Structured Cabling

Commercial projects have stricter requirements:

• Data center buildouts require detailed plan review
• Healthcare and education facilities have additional code requirements
• Work in plenums requires plenum-rated cable (CMP)
• Fire barrier penetrations require proper firestopping

Code Compliance Considerations

Even when permits are not required, professional installations should follow NEC Article 800 standards:

Cable Installation

• Proper cable support and securing
• Separation from power conductors
• Plenum-rated cable (CMP) in air handling spaces
• Riser-rated cable (CMR) for vertical runs between floors
• Proper bend radius maintained

Fire Protection

• Firestopping required for fire-rated penetrations
• Proper sleeve or conduit through firewalls
• Documentation of firestop materials and methods

Grounding and Bonding

• Communications systems must be properly grounded per NEC Article 800.100
• Intersystem bonding termination for new construction
• Bonding of cable shields and racks in commercial installations
