Pro Tips from the Field

• Low-voltage = usually exempt: Most data cabling under 91V doesn't need permits, but verify for commercial projects.
• Follow TIA standards: Even without permits, compliance with ANSI/TIA standards ensures quality and future serviceability.
• Mind fire barriers: Any penetration of fire-rated assemblies triggers additional requirements and likely needs permits.
• Document everything: Maintain as-built drawings and test results for future reference.
• C-7 license required: Commercial work over $500 requires a licensed C-7 contractor.
• Check with specific city: Requirements may vary between cities within Orange County.
