Follow the code, design-review, inspection and permit pathway required at the home’s final destination.
The Destination-Code PrincipleModular construction is normally designed and approved for the rules in force where the completed building will stand.U.S. State Modular-Building ProgramsIn the United States, modular regulation is commonly administered through state or local building-code systems rather than the federal HUD manufactured-housing code.Canadian Provincial Approval and CSA A277Canadian modular projects must satisfy provincial or territorial law and local permits; CSA A277 can support factory certification but is not a universal building-code approval.Factory Inspections and Site InspectionsModular quality assurance uses coordinated inspections in the plant and at the destination because some work becomes concealed before shipment.Approved Plans, Professional Seals and EngineeringModular plans must coordinate architecture, structure, energy and building systems across factory and site work, with professional responsibility appropriate to the destination.Labels, Insignia and Data PlatesRegulatory labels and data plates help connect each module to its approved design, factory inspection program and destination records.Permits, Occupancy and Project CloseoutFactory completion is not permission to occupy. The destination authority must close permits and accept the completed site and building work.
