Key Takeaways:
Modular homes can be built on full basements or crawl spaces with permanent foundations.
Basements add living space, storage, energy efficiency, and resale value.
Crawl spaces are a great alternative when a full basement isn't feasible.
Corey’s Construction’s standard turn-key pricing includes a 9' poured concrete foundation that’s fully insulated.
We serve homeowners across Maryland, Pennsylvania, and West Virginia with complete, code-compliant modular home construction.
When planning a new construction project, especially a turn-key modular home, one of the first things to consider is the foundation. At Corey’s Construction, we’re often asked: Can modular homes have basements? The answer is yes—and they can offer a lot of advantages.
Unlike manufactured or mobile homes, modular homes are permanent structures. They’re built in sections off-site, delivered to your property, and assembled on a permanent foundation—making it entirely possible to include a full basement as part of your design.
In fact, our standard turn-key modular home package includes a 9-foot poured concrete foundation that’s fully insulated, providing a solid and energy-efficient base for your new home.
Why Choose a Basement?
Adding a basement to your modular home opens the door to more flexibility and long-term value:
Extra Living Space – Whether it's a guest room, entertainment zone, or home gym, basements expand your home's functionality.
Additional Storage – Keep seasonal items, tools, and keepsakes organized and out of your main living areas.
Energy Savings – An insulated basement adds a layer of protection from the elements and reduces heating and cooling costs.
Boosted Property Value – Homes with basements typically attract more buyers and higher resale prices.
Crawl Space vs. Basement: What’s Right for You?
Basement Foundation
This is the go-to choice for many of our clients in Maryland, Pennsylvania, and West Virginia. A full basement adds usable space, allows for future upgrades, and acts as a built-in storm shelter.
Crawl Space Foundation
Ideal for sloped lots or areas with high water tables, crawl spaces still raise your home off the ground and provide easy access to plumbing and mechanicals—without the cost of a full basement.
💡 Note: Slab foundations are not suitable for modular homes because space is needed underneath for HVAC, electrical, and plumbing systems.
The Importance of a Strong Foundation
Whether you’re building in Franklin County, PA, Frederick County, MD, or Morgan County, WV, your modular home must meet strict state and local building codes. We build to standards based on the International Residential Code (IRC) and ensure your foundation is tailored to your home’s design and site conditions.
Our typical foundation construction process includes:
Steel I-Beams – The backbone of the structure, distributing weight evenly.
Cross-Members – Adding rigidity and connecting the beams for stability.
Outriggers – Reinforcing the frame and providing lateral strength during transport and beyond.
Concrete & Treated Wood – Chosen for durability, performance, and longevity. (We avoid stone due to its inconsistency.)
At Corey’s Construction, we handle every detail, from excavation to waterproofing and insulation, so your home has a strong, dry, and energy-efficient foundation from day one.
Built to Last, Designed for You
Adding a basement to your modular home isn’t just about more square footage—it’s about building smarter. Our fully insulated 9' poured concrete foundations, included in our turn-key pricing, provide homeowners with the comfort and peace of mind they deserve.
