Manufactured Home Foundation Systems
Choosing the Right Foundation
Your foundation affects how your home looks, how you get in and out, which skirting you can use, and how it performs for years to come. Logan Development prepares and installs manufactured home foundation systems throughout Western Washington, including Kitsap, Jefferson, Clallam, and Mason counties.
Ground Set vs. Pit Set
Ground Set
Preparation
First, we grade and level the home pad. Then, depending on local regulations, we often add crushed gravel as a leveling course.
Drawbacks
You cannot use CMU skirting (block skirting) on ground sets, because the blocks need concrete footings. Instead, ground set homes can use DuraSkirt®, plywood, or vinyl.
Ground set homes sit taller, often requiring more steps for access.
Pit Set
Preparation
We excavate the site, just like a standard home foundation, to prepare for the footings.
Concrete Slab Recommended
Our recommended method for pit sets, as it provides top-of-the-line stability and long-term durability in the Pacific Northwest.
Gravel Pad
Gravel can also provide a sturdy foundation for your manufactured home. With a gravel pad, we highly recommend an Engineered Foundation System.
Engineered Foundation Systems
We recommend this system for homes on gravel pads. Site conditions or lenders may also require it in place of concrete footings.
Home Stabilization & Support
A properly installed home starts with more than the foundation. Tie-downs and drainage protect your investment for the long term.
Tie-Down Systems
Tie-down systems secure the home and add stability during high winds and seismic events. In addition, state, local, or financing rules may call for tie-downs, depending on the installation type and location.
Benefits
- Added stability and security
- Helps protect against shifting and movement
- Often a requirement for financing approval
- Designed to meet applicable installation standards
Our most commonly used system is the Xi2 Foundation System.
Drainage
Proper drainage is one of the most important parts of a successful installation. Managing water runoff protects the foundation area and reduces the risk of long-term moisture issues. We evaluate every site and build in the right grading and drainage.
Drainage may include
- Site grading
- Water runoff management
- Downspouts, gutters & splashblocks (black or white)
- Curtain and footing drains
- I-Pits

Frequently Asked Questions
What is the difference between a ground set and a pit set?
A ground set home sits above grade on a graded, leveled pad. It’s cost-effective and easier to access underneath, but sits taller and often needs more steps. In contrast, we excavate a pit set like a standard home foundation, which gives a lower profile and a more residential look.
What foundation do you recommend for a pit set?
For a pit set, our recommended manufactured home foundation is a concrete slab, because it provides top-of-the-line stability and long-term durability in the Pacific Northwest. A gravel pad is also an option, paired with an engineered foundation system.
When is an engineered foundation system needed?
We highly recommend an engineered foundation system for homes installed on gravel pads. Also, site conditions or lenders may require it in place of concrete footings.
Can I use CMU block skirting on a ground set?
No. CMU blocks need concrete footings, so ground set homes work with DuraSkirt®, plywood, or vinyl skirting instead.
Do manufactured homes need tie-downs?
Tie-downs add stability during high winds and seismic events, and state, local, or financing rules may also call for them, depending on the installation type and location. Our most commonly used system is the Xi2 Foundation System.
