A modular home is a permanent house manufactured in an indoor environment in a factory, transported entirely to a new location, the prefabricated parts are assembled and installed by contractors. Please be noted that a modular home is not a mobile home. It is just built off-site. Modular homes are commonly referred to as factory-built, system-build, or prefabricated homes (prefab).

How Modular Homes Differ from On-Site Built Homes?

Because modular homes are built in factories, 80% of the work is completely indoor. Thus, part of the house can be built within weeks instead of months, and the construction is not affected by the weather. Modular homes must conform to specific rules, guidelines, and building codes that are often stricter.
