Commercial electrical work in unincorporated Hillsborough County can require signed/sealed plans and detailed electrical design information, including service and riser diagrams, loads, panels, wiring methods, grounding, emergency systems, special occupancies, communications/low voltage, and flood elevation where applicable. Commercial new-construction structural criteria also address mechanical, electrical, plumbing, gas, special design, and special flood hazard area requirements. StartFL should treat commercial trade work as scope-specific: an equipment replacement may follow a trade permit, while a larger tenant or construction project can require building-plan, occupancy, fire, and site review in addition to the subtrade permit.
