Technically speaking, the term modular does not denote a style of home, but rather a method of construction. It simply means that the home is precision built in a factory. Modular homes can be one or two storey; single or multi-family homes. Modular construction methods can be used in residential or commercial applications.
Building codes vary by province and regardless of where the building is constructed, the jurisdiction where the building will be located has a mandate to confirm that the building is built to code requirements. For factory-built homes, a certification label, indicating compliance with Canadian Standards Association (CSA) standards, is the building inspector’s assurance that the factory-constructed parts of the building meet local requirements.
