7 Things You Didn’t Know About Modular Homes (But Should)

If you’re looking into building a new home, there’s a good chance you’ve heard of modular homes. But let’s be honest; there’s also a good chance you’ve got questions. Are they the same as mobile homes? Can I customize one? Do they hold their value?

At Corey’s Construction, we build beautiful, fully customized modular homes across Maryland, West Virginia, Northern Virginia, and Eastern Pennsylvania. And we talk to a lot of people who are surprised (in a good way!) when they learn what modular really means.

So let’s clear up the confusion. Here are seven things you probably didn’t know about modular homes — but definitely should.

1. They’re Built to the Same Codes as Traditional Homes

   
   

Let’s tackle one of the biggest myths right out of the gate: modular homes are not the same thing as mobile homes.

Modular homes are built in sections at a factory, yes, but they’re held to the exact same local and state building codes as traditional site-built homes. That means everything from electrical and plumbing to energy efficiency and structural safety is inspected, certified, and up to code. Once it’s placed on a permanent foundation, a modular home is treated like any other house.

Modular homes are constructed in sections (modules) in a climate-controlled factory, then set on a permanent foundation — and they must meet the same locally adopted building codes (IRC/IBC) as site-built homes. That’s a completely different code path from HUD-code manufactured homes. The National Association of Home Builders (NAHB) clarifies this distinction, noting that modular homes are inspected by third parties before leaving the factory and again on site.

2. You Can Customize (Almost) Everything

   
   

“Modular” doesn’t mean cookie-cutter. At Corey’s Construction, each modular home is fully customizable, with hundreds of options to choose from: layouts, elevations, storage, kitchens, baths, porches, and smart-home features. And because modules are engineered to your selections and built indoors, you get tight tolerances (construction precision) and repeatable quality at scale. 

According to the NAHB, this modular building system supports consistent quality and design flexibility that meets or exceeds local building and fire codes.

3. They Appreciate in Value Just Like Site-Built Homes

   
   

There’s a long-standing rumor that modular homes don’t hold their value. We’re here to tell you that’s just not true.

Because modular homes are built to the same codes and placed on permanent foundations, they’re treated the same in the real estate market. When well-maintained and located in a good area, they appreciate just like traditional homes. 

Modular is not the same thing as manufactured: Manufactured homes follow federal HUD standards and are built on a permanent chassis. Whereas modular homes follow state/local codes and are set on permanent foundations — so they’re treated like site-built traditional homes in permitting, inspection, and resale.

The key is quality construction and thoughtful design; two things we take seriously at Corey’s Construction.

4. Financing Is Easier Than You Might Think

   
   

Worried about getting a mortgage? Don’t be.

Most lenders treat modular homes just like any other stick-built home. You’ll have access to conventional loans, FHA loans, VA loans, and construction-to-permanent loan options. At Corey’s Construction, we work with several lenders who are familiar with modular builds, and we’re happy to help guide you through the process.

5. Modular Homes Are Built for Energy Efficiency

   
   

One of the perks of building in a factory? Tighter construction standards and less waste. That means fewer air leaks and better performance when it comes to heating and cooling.

As a new modular home owner, this means less money spent on monthly utility bills, thanks to energy-saving benefits such as:

• Energy-efficient windows and doors

• Superior insulation

• Smart thermostats and zoned HVAC

• Solar-ready roofing options

  
  

Factory construction helps keep materials dry and detailing consistent — great for air-sealing and insulation continuity. Pair that with low-e windows, high-efficiency HVAC, and ENERGY STAR® options for lower monthly bills. 

Over time, that can translate into serious savings on your utility bills.

6.  The Build Time Is Fast — Really Fast

   
   

Here’s where modular homes outshine traditional constructions. While Corey’s Construction prepares your site and foundation, the factory builds your modules indoors. That parallel path plus weather-proof scheduling is why modular construction timelines are typically shorter and more predictable than traditional builds.

Modular homes can typically be move-in ready in 10 to 12 weeks (just a couple of months), while traditional builds often take at least 6 months (usually years). Since construction happens indoors, bad weather isn’t a factor, and factory scheduling is much more efficient. That means fewer delays—and fewer headaches.

7. Modular Homes Are Growing in Popularity

   
   

According to the Modular Building Institute, modular constructions made up about 12.5% of new single-family homes in 2023. In fact, modular’s share of new constructions in the U.S. has been climbing significantly over the last decade — and this momentum is growing.

More homeowners are discovering how cost-effective, efficient, and customizable these homes are. Across the housing industry, offsite and modular approaches keep growing in popularity because they deliver speed, quality control, and cost predictability. 

Bottom Line: What Sets Modular Homes Apart

• Same codes, same inspections: They’re built to the same standards as site-built; they’re just assembled smarter.

• Design freedom: The sky’s the limit when it comes to designs and home features: floor plans, elevations, finishes, and smart-home packages tailored to you.

• Predictable timelines: The fast and efficient parallel site/factory construction process reduces weather delays and uncertainty.

• Energy performance: Energy-efficient and tight construction techniques, combined with modern systems, lower operating and utility costs. 

• Mainstream financing/appraisal: Modular homes are treated like site-built homes by major lending institutions.
