A system built modular home is built to the Uniform Building Code (UBC) and/or the International Residential Code ( IRC). This is the same code used by site contractors to build homes. Instead of building in ever-changing weather conditions, modular homes are built in sections or modules indoors, where they are never subjected to adverse weather conditions. The sections move through our factory, with quality control checking them after every phase of construction. Finished modular sections are covered, sealed and transported to your home site where they are placed on your foundation. After your home is set and the interior is finished, other site work, such as a garage, deck, porch or patio is completed by your Heritage Distributor.
