What is a Modular Home?

Modular homes are the ultimate prefabricated building system. These highly customizable, environmentally-friendly homes are built almost entirely in a factory setting, saving both home owners and builders time, effort and money.

Once the main modules of a new home are constructed — complete with attached walls, floor, ceiling, wiring, plumbing and interior fixtures — they are transported to the home owner’s chosen lot and placed on a permanent foundation by a crane. Each home is designed and constructed to meet all state and national building and fire codes, and a local builder does the final finish work.

Eco-Friendly

Modular homes are green by their very nature. Assembly in an enclosed indoor environment allows them to fulfill key components of green building certifications, including the ICC 700 National Green Building Standard. Going modular means that material waste is reduced at both the factory and the job site. As a result, the environmental impact on the land and the community where the house is being delivered is lessened. Modular homes are often more tightly built and thus more energy efficient, which can result in lower heating and cooling costs for the home owner.

Flexible Home Design

While most manufacturers have a portfolio of home plans to choose from, computer-assisted design (CAD) allows limitless design and customization possibilities when planning a new modular home. Modular construction allows for a quick turnaround between groundbreaking and occupancy. A typical modular house can be move-in ready in about three months. And more often than not, the finished product is indistinguishable from a site-built home.

Saves Money, Saves Time

Designed and constructed to meet or exceed local building codes and allowing nearly 90% of a home to be constructed offsite, a highly customizable home can be built in a controlled factory environment while the building site is simultaneously being prepped.

Most work is done in the factory, so weather delays, missing materials and subcontractor no-shows are all but eliminated, saving time and money. Building modular homes save time and money, allowing the builder to focus on generating sales and other revenue sources.

Quality Construction

homes in a factory setting allows for more consistent quality due to uniform construction processes, training techniques and inspections. All homes are inspected by an independent, third-party home inspection agency before leaving the factory. Once on site, they are again inspected, this time by a local building inspector. These homes meet and often exceed all requirements of locally adopted building and fire codes.
