How Manufactured Homes Are Built
Manufacturers have a team of staff that works in stations to reduce costs, improve quality and consistency, and dramatically reduce the time it takes to construct a new home.
Skilled workers start with base to create framework just like an onsite home. This work is the preparation for the components such as windows and doors produced by others further improves efficiency and streamlines cost.
Environmentally controlled factories allow the sequence of assembly to be altered substantially to improve working conditions and productivity. Bathroom fixtures, furnaces, water heaters, floor coverings, etc. are all installed before the walls and roof structure are put in place. The sequencing of assembly of onsite built homes is strategic to provide the highest standard in weather protection.
At every stage of production all work is inspected, and if remedial work is required, it is corrected before the home moves down the assembly line. Factory building provides for economies of scale which allow homes to be built more efficiently; therefore, generally more affordable then site built construction.
Modular buildings are designed to be placed on basements, crawl spaces, pilings and other foundations compliant with the BC building code.
Factory-Built Homes: Environmental Advantages
Climate controlled factory building procedures ensure optimal insulations and vapor barrier installation. This provides a better insulated product that requires less energy to heat and cool.
Better Environmental Practices with Off-Site Building
Manufactured homes arrive in one or two sections that are 85 percent complete. This allows for greater efficiencies as the construction time frame is reduced by at least 80 percent, as are pollutants such as fuels for compressors and equipment, toxic adhesives and the general impact on the surface surroundings and neighbouring areas.
Better Environmental Practices
With the off–site home being built in one location, all materials for the home are shipped to the location, significantly reducing vehicle use, noise, pollution and other impacts in the area where the home will be situated.
Better Waste and Disposal Recycling
Manufactures buy large quantities of lumber and other materials, much of which is ordered to exact requirements, thereby reducing waste. Of the waste that does occur in the build, there is 50-70% less than when building on-site and can readily be recycled or disposed properly.
What is Factory-Built Housing
As the name implies, factory-built housing refers to homes that are built in a factory, or manufacturing facility. There are a number of building systems that result in varying degrees of completion in the factory before delivery to the building site. Factory-built homes are available in many sizes, designs, and layouts, with a wide selection of standard and customized features.
In BC, manufactured homes are built to the BC building code under the CSA Z240 standard. This standard includes all the information required to direct how the home is to be built. Further, it requires that the home is to be built on a steel frame to accommodate efficient transportation. The frame remains with the home permanently.
Modular-built homes are produced in a factory as three-dimensional modules that may be combined on-site to make one-, two- or three-storey homes. Typically, a bungalow will consist of one or two modules, while a two-storey home will use four or five, or more modules. The homes are typically set on full-perimeter foundations—a crawl space or full basement—but may also be placed on surface-mount foundations.
Insulation, air/vapour barrier, plumbing, wiring, exterior siding and other construction details are largely completed in the factory. Interior work is usually well advanced, including drywall, trim, flooring, cabinets and bathroom fixtures. Finishing the home on-site generally takes a couple of weeks, sometimes more, depending on the size, style and features of the home. Some features are best done on-site, such as brick siding and some types of flooring.
In BC, modular-built homes are built to the BC building code under the CSA A277 standard. This standard requires the manufacturing plant to be certified by a third party inspection agency to ensure that the plant has the knowledge and experience to build homes to the respective provincial and local building codes.
Manufactured & Modular Home Facts
- Modular-built homes appraise the same as their on-site built counterparts do. They do not depreciate in value.
- Manufactured homes are of high quality and are built to last for the same time period as any other form of housing.
- Manufactured and modular-built homes can be customized.
- Manufactured and modular-built home designs vary in style and size.
- Manufactured and modular-built home construction can also be used for commercial applications including office buildings.
- Manufactured and modular-built homes can be permanent structures and real property.
- Manufactured and modular-built homes can be built on crawl spaces and basements.
- Manufactured and modular-built homes are considered a form of Green Building.
- Manufactured and modular-built homes are faster to build than a 100% site-built home.
- Home loans for modular-built homes are the same as if buying a 100% site-built home. Because manufactured homes are considered chattel, a different form of financing is available with insurance available through insuring agencies such as the Canadian Mortgage and Housing Corporation.
- Insurance underwrite for modular-built homes is the same as a 100% site-built home.
- Taxes on modular-built homes are the same as 100% site-built home.
- Modular-built homes can be built to withstand 175 mph winds.
- Manufactured and modular homes can be reconfigured for future convenience.
