Manufactured Home Foundation Types: Piers, Runners, Slab, and Permanent (What You Need — and Why)

Ask five different manufactured home buyers what a "permanent foundation" is and you'll get five different answers — and that confusion is one of the reasons good buyers end up with the wrong setup, the wrong loan, or a surprise repair bill three years later. The foundation your home sits on determines more than most people realize: your insurance premium, the loans you qualify for, how well the home rides out a storm, and what the home is worth when you go to sell it.

The good news is that the whole topic is actually pretty simple once someone lays it out honestly. Below is a plain-English guide to the four foundation types you'll see across TX/AR/OK/LA — pier-and-beam, runners, slab, and true permanent foundations — plus how to talk about them with your dealer, lender, and installer without getting talked into something you don't need.

Why the foundation matters more than buyers expect

A manufactured home is engineered to sit on a set of engineered supports, not simply "on the ground." That set of supports — the foundation — has to do four different jobs at once:

• Hold the home level so doors, windows, and marriage-line seams work correctly for the life of the home.
• Anchor the home against wind, so it can't shift, tilt, or overturn in a Texas storm.
• Keep water and pests out of the space underneath the home.
• Meet the rules of whichever authority applies to your land — HUD, your state, your county, your lender, and sometimes your insurer.

The foundation type you choose is what makes all four of those jobs possible. It's also the number-one thing that changes whether a home is treated as personal property (like a vehicle) or real property (like a house) — which, in turn, changes your loan options, your taxes, and your resale value. That's why understanding your foundation options is worth taking seriously before you sign anything.

If you're new to the buying process overall, our how to buy a manufactured home guide walks the full path; this article zooms in on the piece under the home.

Foundation type 1: Pier-and-beam (the most common setup)

Pier-and-beam — sometimes called "pier and pad" — is the traditional and most common setup for a manufactured home in the Ark-La-Tex. In this setup, the home rests on engineered piers (concrete or steel columns) spaced out under the steel I-beams that run the length of the chassis. Each pier sits on a pad — a concrete footing designed to spread the load out on the soil.

Key features of a properly installed pier-and-beam setup:

• Engineered pier spacing based on the home's weight and the soil report on your lot.
• Anchors and tie-downs — steel straps and ground anchors that keep the home from lifting or shifting in high wind.
• A "marriage line" support on a double-wide, where the two halves of the home meet.
• Skirting around the perimeter — vinyl, block, or brick — to keep out weather, animals, and debris.
• Access panels so plumbing, HVAC, and electrical can be inspected and serviced.

Pier-and-beam is popular because it's cost-effective, easy to level over time, and fully compliant with HUD standards when installed by a licensed setup crew. It's also the setup you'll see on most chattel (personal property) loans. Where it can hit a wall is when a lender or program specifically requires a permanent foundation — more on that below.

Foundation type 2: Runners (concrete strip footings)

"Runners" refers to long concrete strip footings poured under the length of the home, with the piers set on top of the runners instead of on individual pads. You'll sometimes hear this called a "ribbon foundation" or "strip footing."

Compared to pier-and-pad, runners offer:

• More continuous load distribution on soils that need extra spreading — often used where clay soils shift with moisture, common in parts of Texas and Louisiana.
• A cleaner, more uniform pier layout because the piers can be positioned along the runner rather than each on a separate pad.
• Easier compliance in some counties that prefer or require strip footings on specific soils.

Runners cost more up front than individual pads because it's more concrete. In exchange, you often get better long-term leveling stability, which matters in areas where the soil moves seasonally. Whether runners are worth it for your specific lot is a soil-and-site question — one your installer should answer using the site prep plan, not a rule of thumb. Our site prep and permits guide covers what a proper site plan should include.

Foundation type 3: Slab (concrete pad)

A slab foundation is a solid, poured concrete pad — usually 4 to 6 inches thick, sometimes thicker at the edges — that the home is set onto and then anchored to. There's no crawl space; utilities usually come up through the slab.

Slabs are common when a buyer wants:

• A very stable, low-maintenance base with no crawl space to inspect.
• A cleaner look because there's no visible skirting.
• A setup that some counties or HOAs prefer for aesthetic or drainage reasons.

Slabs come with trade-offs worth knowing about before you sign:

• Higher up-front cost than pier-and-beam because a slab is significantly more concrete and rebar.
• Harder to re-level later if the soil moves — a slab either moves as a unit or cracks; you can't just adjust a pier.
• Utility access matters — plumbing that fails under a slab is a harder repair than plumbing under a crawl space.
• Slab alone does not automatically make the home a "permanent foundation" — that's a common misconception.

If you like the look and feel of a slab, that's a perfectly good choice — just go in with eyes open on cost, maintenance, and what your lender actually requires.

Foundation type 4: Permanent foundation (the FHA/VA/USDA definition)

"Permanent foundation" is a specific, technical term — not a marketing phrase. The clearest working definition in most of the country comes from the HUD Permanent Foundations Guide for Manufactured Housing (PFGMH), which is the standard your FHA, VA, and USDA loans reference. A permanent foundation, in that sense, has to:

• Be site-built to an engineer's design for your specific home and soil.
• Have footings below the local frost line, keyed and reinforced.
• Fully anchor the home to the foundation with all-thread rods, straps, or equivalent — not just tie-downs to the ground.
• Have the wheels, axles, and tongue removed.
• Be certified by a licensed engineer who's inspected the finished installation.

That certification is what your lender and insurer will actually ask for — it's a stamped document, not a verbal claim. Common permanent foundation designs include:

• Perimeter wall — poured or block wall around the entire home, on continuous footings.
• Slab with perimeter wall — combines a slab pad with a knee wall.
• Basement or crawl-space — dug and walled below the home, common in some markets.

Why does this matter? Because most FHA, VA, and USDA loans on a manufactured home require a permanent foundation and real-property status — meaning the home is taxed and titled like a house, not a vehicle. That's the pathway to the widest set of loan programs and often the best rates. It also generally protects resale value, since future buyers can also finance the home more easily.

For the trade-offs between the different lending pathways — chattel vs. real property, FHA vs. VA vs. conventional — our manufactured home financing 2026 guide walks through it without pushing you toward any one lender.

Personal property vs. real property (why the foundation decides)

Under most state laws, a manufactured home starts life as personal property — same category as a car, complete with a title from the state DMV. Once installed on a permanent foundation and legally "affixed" to the land (via a Statement of Location, Affidavit of Affixation, or similar document, depending on your state), the home can be converted to real property — taxed with the land as one parcel, titled with the deed.

Why the difference matters:

• Loan options. Real property qualifies for more loan programs — FHA, VA, USDA, and most conventional mortgages. Personal property typically routes to chattel loans with shorter terms and different rates.
• Property taxes. In most states, real property taxes are set by the county assessor; personal property is often assessed differently and can be reassessed each year.
• Insurance. Real-property status usually gives you standard homeowners insurance options; personal property may need a mobile-home-specific policy. Either way, understanding your manufactured home insurance basics before closing is worth the fifteen-minute read.
• Resale. Homes on permanent foundations attached to land generally sell more easily and hold value better because more buyers can finance them.

None of this means chattel/personal-property is bad — it's often the right answer for a buyer who owns land, wants a fast setup, or plans to move the home later. It just needs to be a choice, not something that happens to you.

Which foundation type do you actually need?

There is no single right answer — the honest answer depends on four questions:

1. What loan or program are you using? FHA, VA, and USDA typically require a permanent foundation with engineer certification. Chattel loans usually don't.
2. What does your county or municipality require? Some counties require specific foundation types on certain soils, in floodplains, or in wind zones.
3. What's the soil on your lot? Clay soils that move seasonally may argue for runners; stable soils may be fine on pier-and-pad; expansive soils sometimes point toward a slab or perimeter wall.
4. How long do you plan to keep the home in place? A home you plan to keep permanently benefits more from a permanent foundation than one you plan to move within a few years.

A good dealer will ask those four questions early — before showing you homes — because the answers change what setup and financing paths are open to you. If you're comparing dealers, our list of questions to ask before buying a manufactured home has the exact wording to use.

Questions to ask your dealer, installer, and lender

For your dealer:

• Which foundation types is this specific home approved for by the manufacturer?
• Which foundation type do you recommend for my lot, and why?
• Can I see the engineered setup plan and the anchor schedule?

For your installer:

• Do you install to the HUD PFGMH standard, and can you certify the foundation on completion?
• What's the anchoring plan for the wind zone my lot is in?
• How is drainage handled around the perimeter to prevent settling?

For your lender:

• Which foundation type does my loan program require?
• What documentation do you need at closing — engineer certification, affidavit of affixation, or a specific inspection?
• How does foundation choice affect my rate options? (You're asking about program requirements, not shopping rates — clarity here saves surprises later.)

The right professionals on your side will welcome these questions and answer them without pressure.

Key takeaways

• The foundation isn't just support — it decides your loan options, your taxes, your insurance, and your resale.
• Pier-and-beam is the most common setup in the Ark-La-Tex and works well for chattel loans and many buyer situations.
• Runners and slab are stability upgrades over pier-and-pad, useful on certain soils or when buyers want a specific look.
• "Permanent foundation" is a specific technical standard — required by most FHA/VA/USDA loans and certified by an engineer.
• Personal vs. real property hinges on the foundation and affixation — and it changes what loans, taxes, and insurance apply.
• Your soil, your loan program, and your county decide which foundation type is right; not a rule of thumb.
