Structured Cabling Permit Requirements in Erie County, New York

Quick Answer: Structured cabling permits in Erie County are handled at the municipal level—Buffalo, Amherst, Cheektowaga, and other municipalities each have their own building departments. Unlike security and fire alarm work which requires state licensing, data and network cabling contractors are regulated locally. Most commercial structured cabling projects require a low voltage or electrical permit, especially when penetrating fire-rated assemblies.

Understanding Erie County's Permit Structure

Erie County includes over 40 municipalities, each administering their own building codes based on the Building Code of New York State (BCNYS). For structured cabling work, permit requirements vary by location and project scope.

The City of Buffalo follows the New York State family of codes, including the 2023 NEC (National Electrical Code), with the 2025 NYS Uniform Code taking effect December 31, 2025.

When Permits Are Required

Most Erie County municipalities require permits for structured cabling when:

• Penetrating fire-rated walls, floors, or ceilings - Fire-stopping documentation required
• Installing cable pathways - New conduit, cable tray, or J-hook systems
• Commercial new construction - Low voltage included in overall building permit
• Running cables in plenum spaces - Requires plenum-rated (CMP) cable
• Installing telecommunications rooms - MDF/IDF buildouts
• Projects over 50 cable drops - Larger commercial installations

When Permits May Not Be Required

Permit exemptions typically apply for:

• Residential single-family home cable installations
• Simple patch cable connections and outlet additions
• Replacement of existing cables in same pathways
• Minor modifications under 10-15 cable drops (varies by municipality)
• Work that doesn't penetrate fire-rated assemblies

Always verify with your local building department—permit thresholds differ across Erie County's municipalities.

New York State Licensing Overview

New York takes a hybrid approach to low voltage licensing:

State-Level License (Security/Fire Alarm)

The NYSDOS Security or Fire Alarm Installer License is required for:

• Security alarm systems
• Fire alarm systems
• CCTV used for security monitoring
• Access control systems

Structured Cabling (No State License)

For pure data/network cabling with no security or life safety functions:

• No statewide license requirement
• Licensing handled at municipal level
• Some municipalities require contractor registration
• Buffalo requires contractor registration since 1989

For complete state licensing information, see our New York Low Voltage License Guide.

Location	Cable Type Required	Notes
Plenum spaces	CMP (Communications Plenum)	Above suspended ceilings used for air return
Vertical risers	CMR (Communications Riser)	Penetrating more than one floor
General purpose	CM or CMG	Standard commercial installations
