Unlike traditional homes, modular homes are constructed in a warehouse, transported to the build site, and assembled. If you've ever wondered how modular homes are built, step-by-step, this guide explains what you need to know.
Modular construction begins with the design. Modular homes are highly customizable across models.
The modular home build begins. Individual pieces called modules are constructed in the modular home factory on an assembly line. The frame and structural components are first. Then, the wiring, plumbing, external rough-ins, insulation, drywall, and extra components like cabinets, shelving, and mirrors are installed. Approximately 80% to 90% of the build is finished off-site.
Here's what happens in the factory versus on your land:
|
Factory |
On-Site |
| Structural framing | Module assembly |
| Base floors and walls | Some drywall finishing |
| Doors and windows | Roofing, siding, and HVAC |
| Wiring and plumbing rough-ins | Utility connections and turn-on |
| Insulation | Cabinets, furniture, and appliances |
| Drywall finishes | Tile, wood floors, and fixtures |
All modules must meet quality and safety standards. An assessment isn't exclusively done at the factory. It's a multistep process, including after the home is assembled. Official inspectors are involved, especially after the home is built. Modular homes are held to the same standards as conventional homes.
Modules are transported to the build site using specialized trucks and cranes. Other supplies may be transported, like roofing, electrical, plumbing, and extra drywall.
The site may also be prepped by:
Modular home assembly happens on-site. Modules are assembled, aligned, secured, and sealed. Interior finishes, like cabinetry, interior customizations, flooring, decor, and appliances, are installed.

A final walk through is completed with the customer to ensure the home meets their standards. The homeowner has the opportunity to ask questions or raise concerns and review the build.
