Because the factory pace differs from that of the construction site, the manufactured home enforcement system is necessarily different, too. Ideally, a building code should be backed up by uniform and consistent enforcement. Uniformity and consistency can be maintained better in the HUD enforcement system because of two key factors. The inspections take place in the factory, during each phase of construction, and follow behind the manufacturer's own in-plant inspection and quality assurance teams. This allows for more thoroughness, since time is spent inspecting homes rather than traveling to inspection sites.
Efficiency is increased because travel time is limited and necessary paperwork is minimized.
Consistency is maintained because fewer people inspect more homes. The enforcement procedure is much less susceptible to individual interpretations, as would be the case with on-site inspections in every jurisdiction across the country. In the course of each plant visit, the IPIA shall make a complete inspection of every phase of production and every visible part of each home in production. Keep in mind that all this is in addition to the inspections carried out by the manufacturer's own foremen and its quality assurance inspectors. Before leaving the factory, each home must have a numbered certification label affixed to the exterior of each section of the home.
