A general contractor may plan and manage the renovation, coordinate trades, order materials, schedule inspections, oversee site work, manage changes and remain responsible for the overall project delivery.
Permits may be required for structural changes, additions, plumbing, electrical, HVAC, occupancy changes and other work. Requirements vary by municipality and project scope.
