Pro Tips from Experienced Contractors
Document code compliance. Even without permits, maintain records of cable types used, especially in plenum spaces. Future inspections may request proof of compliant materials.
Use plenum-rated cable when in doubt. Many Henrico County commercial buildings have plenum ceilings. The cost difference is minimal compared to rework liability.
Coordinate with building management. Commercial properties often require contractor registration, insurance certificates, and scheduled access. Get requirements early.
Firestop all rated penetrations. Even if cabling is permit-exempt, penetrations through fire-rated assemblies require proper firestopping. Document all firestop installations.
Keep license current. Virginia does not require continuing education for ESC, but ensure your license remains active. Expired licenses can result in stop-work orders.
