If I’m buying or selling a manufactured home in Wind Zone II Alabama, I’d expect the inspector to focus first on wind rating, tie-downs, roof and water entry, and HUD paperwork. On the Gulf Coast, homes may need to handle winds up to 100 mph, so missing labels, weak anchors, loose roof areas, or moisture damage can affect safety, insurance, and loan approval.
Here’s the short version of what gets checked:
HUD labels and data plate to confirm the home is built for Wind Zone II
Piers, footings, blocking, anchors, and straps under the home
Marriage wall connections on double-wide homes
Roof, flashing, siding, windows, and doors for wind and water issues
Interior stains, soft floors, and moisture signs
HVAC, plumbing, and electrical for safe working condition
A few items can slow or stop a deal fast:
Missing HUD certification labels
Missing or unreadable data plate
Poor anchoring or tie-down setup
Active leaks or soft subfloor areas
Electrical or plumbing defects that affect insurance or repairs
Check Area | What I’d Want Confirmed | Why It Matters |
HUD paperwork | Wind Zone II label, serial details, install record | Loan and insurance review |
Support system | Piers, pads, blocking, leveling | Structure and floor performance |
Tie-downs | Strap count, tension, corrosion, anchor placement | Wind resistance |
Exterior shell | Roof, siding, flashing, seals | Rain and storm exposure |
Openings | Windows and doors latch and seal | Wind pressure and water entry |
Interior and systems | Moisture, HVAC, plumbing, electrical | Safety, repairs, living conditions |
In short, I’d view this inspection as a check of whether the home is identified correctly, set correctly, sealed correctly, and working safely.

HUD Labels, Data Plates, And Installation Records
The inspector begins by confirming the home's identity documents. Two items matter most: the HUD certification label on the outside and the HUD data plate on the inside. The inspector also checks installation records to see whether the home was set, anchored, and tied down the right way.
HUD Certification Labels And The Interior Data Plate
The HUD certification label is a small 2-by-4-inch red metal label riveted to the outside of each section, often on the rear side or near the main entry door. It includes a manufacturer state code and a six-digit number. On a double-wide, there should be one label on each section, so the inspector looks for both.
The interior data plate is a paper label usually located inside the kitchen sink cabinet, a bedroom closet, or near the main electrical panel. It lists the manufacturer, serial number, model, date of manufacture, and wind zone. The plate should show Wind Zone II or higher. Wind Zone I does not meet coastal Wind Zone II exposure.
That label check gives the inspector a starting point. It shows whether the home was built and installed for Wind Zone II conditions.
If the labels are still in place, the inspector uses them to confirm the home's wind rating and construction details before moving on to the structure itself.
Why Missing Or Unreadable Labels Can Slow Closing
If the HUD label or data plate is missing or unreadable, the inspector records it as a major finding. Lenders and insurers use these labels to confirm the home was built under the federal HUD Code after June 15, 1976, and to verify the home's manufacturer, serial number, and date of construction.
Alabama requires both labels on manufactured homes built after June 15, 1976. If either one is missing, buyers may need extra verification before a lender or insurer will move forward. That can slow financing and push back closing.
The interior data plate may look minor, but it holds key details for financing and insurance.
Those documents set the baseline for the next check: how the home was anchored and supported.
Foundation, Piers, Blocking, Tie-Downs, And Marriage Wall Connections
The inspector looks closely at the system under and around the home: piers, footings, anchors, and straps.
Piers, Blocking, And Support Conditions
The inspector checks pier spacing, whether the piers are plumb, and how well they bear weight. Piers need to rest on approved footings or pads, not bare soil. Blocks placed straight on the ground are a common defect, and they often do not meet FHA and VA standards.
Blocking matters just as much as pier placement. Compressed plywood shims and uncapped hollow blocks are both warning signs. When piers settle unevenly, the problems usually show up inside first. Floors may slope, doors may stick or fail to latch, and interior wall seams may start to crack. At each shear-wall location, Alabama requires both a support pier and an anchor.
Anchors, Straps, And Tie-Down Systems
In Wind Zone II, the number of vertical and diagonal ties on each side depends on the length of the home:
5 ties per side for homes up to 40 feet
7 ties per side for homes 41 to 60 feet
9 ties per side for homes 61 to 90 feet
A vertical tie must also be installed at every diagonal tie location. If pier height is more than 24 inches, one more diagonal tie is required for each extra 12 inches of height.
The inspector checks every visible strap for proper tension, the right angle, and any rust or corrosion. Along the Alabama Gulf Coast, salt air can wear down galvanized steel, so corrosion comes up again and again. Longitudinal ties are also required under Alabama’s minimum anchoring rules because they help stop the home from shifting from one end to the other.
Marriage Wall Separation And Structural Movement
On double-wide homes, the inspector checks the marriage wall for gaps, separated trim, uneven floors, and daylight showing between sections. Alabama requires the sections to be fastened and sealed according to the manufacturer’s instructions.
These signs often point to movement or poor sealing. They can also affect moisture intrusion and financing.
Next, the inspector checks the roof, siding, windows, and doors for wind damage and moisture entry.
Roof, Siding, Windows, Doors, And Interior Moisture Signs
After checking support and anchoring, the inspector moves to the home’s weather barrier. That means a close look at the roof, siding, windows, doors, and any interior signs that water may be getting in.
Roof Covering, Flashing, And Exterior Wall Condition
The inspector looks for missing or lifted shingles, sagging roof areas, and failed ridge caps. On older metal roofs, rust and seam failure often show up. A roof-over can add extra weight and may hide damage beneath the newer layer.
Flashing gets extra scrutiny at the marriage line on double-wide homes, where the two roof sections meet. That seam is a common spot for leaks. In Wind Zone II, roof coverings and trusses near gable ends must be engineered to handle 73 psf (pounds per square foot) of pressure. Because of that, any sign of uplift or separation along those edges is a serious red flag.
Siding checks focus on loose panels, failed caulk, and gaps at corners or trim joints where wind-driven rain can work its way inside.
Windows And Exterior Doors In Higher-Wind Areas
The inspector tests windows and doors to make sure they open, close, and latch as they should. They also check frame condition, weatherstripping, glazing, and seals for signs of water entry. In many cases, seal failure first shows up as leaks around frames and thresholds.
In Wind Zone II, a window or door that doesn’t latch securely is a safety concern. If seals fail or glazing breaks during a storm, pressure can build inside the home and put the roof at risk. Corner wall areas in Wind Zone II must resist pressures of ±48 psf, which is why secure latching and tight seals matter so much.
Interior Stains, Soft Spots, And Moisture Concerns
Ceiling stains, wall discoloration, and soft flooring, especially near windows, doors, or the marriage line, often point to failure in the exterior shell.
A moisture meter helps confirm what a visual check may miss. Thermal imaging can also help spot hidden moisture intrusion or insulation gaps that aren’t visible to the naked eye.
After the exterior shell, the inspector checks HVAC, plumbing, and electrical systems for safety and function.
HVAC, Plumbing, Electrical, And What The Findings Mean For Buyers And Owners
HVAC, Plumbing, And Electrical Checks
After the shell is checked, the inspector moves to the systems that make the home safe, livable, and functional.
On the HVAC side, the inspector confirms that the heating and cooling equipment is listed for manufactured home use, that whole-home ventilation is in place, that kitchen and bath fans exhaust to the outside, and that gas appliances vent directly outdoors. Ductwork under the home also gets close attention. Disconnected ducts or ducts damaged by rodents are common trouble spots, and they often lead to comfort issues and higher energy use.
Plumbing checks start with the supply lines. Gray polybutylene pipe, found in some older manufactured homes, has a history of failure and can make insurance harder to get. The inspector also looks for leaks under sinks and toilets, since even a slow drip can damage the particleboard subfloor over time. Other items include a water heater drip pan, a proper TPR valve, and a pressure regulator when water pressure is above 80 psi. Any visible drain lines under the home are checked for disconnections or blockages.
The electrical inspection covers the main panel, branch wiring, and receptacles. One manufactured-home-specific item is making sure the chassis or frame is bonded with a #8 copper wire. The inspector also verifies that aluminum branch wiring is not present and that neutrals and grounds are separated in the panel. GFCI protection is checked in kitchens, bathrooms, and exterior outlets.
How Inspection Findings Affect Repair, Insurance, And Financing Decisions
These defects matter for a simple reason: they can change repair costs, insurance options, and whether a lender will approve the loan.
Missing HUD Certification Labels or a missing data plate can stop FHA financing and make insurance more complicated. If a label is missing, an IBTS Performance Certificate can serve as a replacement.
Some findings, like weak anchoring or active plumbing leaks, often lead to repair talks or seller credit requests. Floor soft spots from long-term plumbing leaks are a good example. In a manufactured home, full floor replacement usually costs $3,000 to $10,000, depending on the size of the home.
In high-wind coastal areas, hurricane and named-storm deductibles are often set at 2% to 5% of the home’s insured value. That means inspection findings can affect not just repairs, but the day-to-day cost of owning and protecting the property.
Conclusion: Key Items That Matter Most On A Wind Zone II Manufactured Home
For buyers and owners, the main inspection priorities are identification, support, tie-downs, exterior weather protection, moisture signs, and the core systems. Each one connects directly to safety, insurability, and repair decisions.
FAQs
Do all manufactured homes in Alabama qualify for Wind Zone II?
No. Manufactured homes are built and certified for specific wind zones based on how they’re designed and where they’re meant to be placed.
In Alabama, only Baldwin County and Mobile County are in Wind Zone II. The rest of the state is in Wind Zone I.
A Wind Zone I home cannot be installed in a Wind Zone II area. But a home with a higher wind rating can be installed in a lower-rated area.
What if the HUD label or data plate is missing?
Missing or unreadable HUD labels and data plates can slow down financing and insurance. Lenders and insurers use them to confirm the home’s federal certification and wind zone rating.
Your inspector should note any visible serial numbers on the steel chassis, along with other markings. In some cases, the serial number, title records, or past inspection reports can help confirm the home’s history and construction details.
Who repairs tie-down or anchoring problems before closing?
Contractors usually fix tie-down or anchoring issues before closing. The work has to meet approved standards.
Repairs can include re-tensioning current straps with rated hardware, replacing damaged or rusted straps, adding anchors suited to the site, or rebuilding piers with solid blocks and concrete pads. After that, some lenders or insurers may ask for an engineering foundation certification.
