Pro Tips from Local Contractors
No LLE here: This is critical. Shelby County doesn't accept state LLE licenses, catching many contractors off guard on Memphis-area bids.
Seismic zone: Memphis area has seismic requirements due to the New Madrid Fault. Cable tray and equipment mounting may need additional consideration.
Use the permit portal: Shelby County's online system helps track permit status efficiently.
Plan for plenum: Most commercial buildings require CMP cable in ceiling spaces.
