Frequently Asked Questions
Project cost depends on scope, design, structural work, labour, materials, permits, subcontractors, site conditions and schedule. Compare detailed estimates based on the same plans and specifications.
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.
Design-build combines design and construction responsibility within one team. Traditional delivery may involve separate designers and contractors. Compare accountability, pricing, schedule and design flexibility.
