While most structured cabling work is permit-exempt, certain conditions trigger permit requirements:

• Electrical work: Any modifications to electrical panels or power circuits
• Building penetrations: Major structural penetrations for conduit runs
• Fire alarm integration: Data cabling connected to fire alarm or life safety systems
• New construction: Low voltage rough-in as part of larger permitted construction
