Site-Built vs. Factory-Built Modular Homes
Site-Built vs. Factory-Built Modular Homes
A better home starts with a better process. Factory-built construction removes the guesswork, giving you a smoother experience from start to finish. It’s the smarter, more reliable way to bring your vision to life.
What’s the Difference Between Site-Built and Factory-Built Homes?
For many homeowners, the homebuilding process starts with confusion: What’s the difference between site-built, modular and manufactured homes?
At Wisconsin Homes, we build high-quality modular homes, crafted inside a climate-controlled facility and built to the same UDC building code required for traditional site-built homes. Modular does not mean manufactured—it means precision-built, engineered for strength, and designed to last.
This page helps you compare both methods so you can make an informed, confident decision.
Explore Floor PlansModular vs. Site-Built: A Clear, Side-by-Side Comparison
Structural Strength
-
Modular Homes: Built in sections that must endure transportation, lifting and placement by crane. This requires stronger floors, framing and engineering than most site-built homes.
-
Site-Built Homes: Built directly on the foundation. Structural strength varies by builder, weather conditions and subcontractor schedules.
✔ Advantage: Modular. Engineered to exceed standard residential requirements.
Building Environment and Quality Control
-
Factory-Built Modular: Constructed in a climate-controlled facility, protected from rain, snow and extreme temperature swings. Materials stay dry.
-
Site-Built Construction: Exposed to weather during framing and finishing, increasing risks of moisture, delays and inconsistent results.
✔ Advantage: Modular. Predictable quality.
Cost Predictability
-
Modular Homes: Pricing is established upfront. Labor is in-house. Materials are purchased efficiently. Fewer delays mean fewer cost surprises.
-
Site-Built Homes: Costs can escalate due to subcontractor delays, weather, change orders and fluctuating material prices.
✔ Advantage: Modular. Fewer surprises and better budget control.
Timelines and Scheduling
-
Modular Homes: Your home is built indoors while your builder prepares your site. Factory schedules are consistent, with no weather delays.
-
Site-Built Homes: A single storm can halt progress for days or weeks. Busy subcontractor schedules often lead to long gaps.
✔ Advantage: Modular. Faster and more reliable timelines.
Customization and Flexibility
A common misconception is that modular homes limit your design freedom. That’s simply not true.
-
Can I change the floorplan? Yes.
-
Can I customize options and finishes? Yes.
-
Is everything known upfront? Yes. No surprises.
With site-built homes, customization often requires hiring an architect, typically costing $4,000 or more. With modular, you can customize without added architectural fees.
✔ Advantage: Modular. More freedom with less cost.
