Baldwin County Manufactured-Home Crawl Spaces: Plan the Repairs

For a manufactured home in Baldwin County, define what is being repaired before accepting a crawl-space or encapsulation quote. The home's bottom board, the ground vapor retarder, the perimeter skirting and the supports are separate parts of the project. A proposal should identify each affected part, the water source being investigated and the person responsible for the work. This guide helps homeowners prepare questions for the manufacturer, installer, repair trades and reviewing offices. It is not a repair specification, foundation certification or individual permit determination. Do not crawl beneath a damaged home, cut open a sagging belly, move supports or alter tie-downs yourself.

Start with the home's identity and instructions

The Alabama Manufactured Housing Commission's FAQ explains that the data plate records information such as manufacturer, serial number, construction date and design-zone information. The exterior HUD label identifies a home built to federal manufactured-housing standards. Keep available identification photographs, installation records and the homeowner's manual together. If these records are missing, ask the manufacturer or commission how to establish the correct home information before specifying changes. HUD's homeowner resources say new manufactured homes come with operation, maintenance and repair information, including the manufacturer's installation and anchoring procedures. HUD also advises consulting the appropriate authority before significant structural changes. A generic detail for a site-built crawl space should not replace the instructions and review relevant to this home.

Keep four parts of the quote separate

The HUD-hosted technical publication Moisture Problems in Manufactured Homes describes a floor system enclosed underneath by a bottom board, often called belly material. It explains that openings can admit moisture and that water from a leak can collect within that floor cavity. That is a different location from water lying on the soil below the home.

Bottom board or belly material: Ask which floor-cavity areas will be inspected, how hidden wet materials will be evaluated and who restores any openings made by repair trades.
Ground vapor retarder: Ask what covering is proposed at soil level and how it fits the home's approved moisture-control approach. It does not establish that damaged materials higher in the floor have been repaired.
Skirting or perimeter enclosure: Ask how access, ventilation and any applicable floodplain requirements will be maintained. New skirting is not evidence that the underfloor work is complete.
Supports, foundation and anchorage: Identify any proposed changes explicitly and route them to the appropriate qualified installer or design professional. Do not treat leveling, supports or tie-down work as an unnamed extra in a moisture quote.

Use these labels when comparing photographs and estimates. “Replace the plastic underneath” is too ambiguous: ask whether the bidder means the belly material, the ground covering or both. The encapsulation-versus-vapor-barrier guide explains conventional moisture-work terms, but the manufactured home's floor assembly needs its own defined scope.

Confirm the local and state review routes

Baldwin County's permitting FAQ directs owners to check building-permit jurisdiction for their parcel. County jurisdiction covers most unincorporated areas plus Elberta, Magnolia Springs and Perdido Beach; other municipal and police-jurisdiction areas require their own checks. A Baldwin County mailing address is not enough to choose the office. For manufactured homes, the county FAQ distinguishes installation/setup and outside electrical work from roofing, HVAC, plumbing and interior alterations/repairs that the county building department does not permit or inspect. That distinction is not a declaration that excluded work is unregulated or that no other approval is needed. Send the actual scope to the responsible office and ask where each portion should be reviewed. The Alabama Manufactured Housing Commission's installer page says manufactured-home installation must be performed by a commission-certified installer and provides a way to check current certification. Ask the commission how a proposed alteration to an existing home's setup, supports or anchorage should be handled. This guide does not classify every maintenance task as installation.

Do not cover installation work before the required inspection

For projects following the county's manufactured/mobile-home installation process, Baldwin's inspection guide places the manufactured-home final after installation and tie-down but before skirting. It lists checks involving tie-downs, service connections, entry arrangements and the AMHC installation decal. It also identifies additional foundation/elevation-document steps for applicable flood-zone installations. That is an installation inspection sequence, not a blanket schedule for every existing-home repair. Ask your reviewer which inspections apply to this project and what must remain visible. Put the answer in the work order so a skirting crew or moisture contractor does not arrive before the required review. If floodplain or enclosure questions remain, use the Mobile and Baldwin planning section as a starting checklist for the responsible local office.

Write a close-up plan for the floor cavity

The HUD-hosted moisture guide describes the importance of identifying the water source and inspecting affected floor-cavity materials. Use that principle to ask for a documented sequence rather than a cosmetic patch. Do not direct a contractor to close an opening simply because the exterior surface looks dry.

Investigation: Who identifies the source and documents the affected area? Which areas remain concealed or inaccessible?
Trade repair: Who handles any plumbing, HVAC, electrical or structural issue that is outside the moisture contractor's assignment?
Material decision: Who evaluates wet insulation and damaged floor materials, and what findings support the proposed repair?
Before close-up: Which inspection or professional review must occur, and what photographs or written findings will be provided?
Restoration: Who restores belly material, ground covering, skirting and access after every trade has finished?

A useful estimate also states how newly discovered damage will be reported, who approves a revised scope and which items are excluded. Ask for enough photographs to distinguish the floor cavity from the ground-level work. These records help you understand what was completed without personally entering an unsafe area.

Crawl Space Inspection Report graphic listing five fields: location and photos, moisture observations, wood plumbing and drainage, areas not inspected, and follow-up scope. — Crawl Space Compass inspection-report graphic. Use its recordkeeping fields for each part of the job. The illustration does not depict a manufactured-home assembly or an approved installation detail.

Text equivalent of the graphic: Crawl Space Inspection Report: five fields to request in written findings. (1) Location and photos: date, area, viewpoint and photo references. (2) Moisture observations: water, dampness or staining; readings with time and location, if taken. (3) Wood, plumbing and drainage: describe visible conditions and separate observations from suspected causes. (4) Areas not inspected: name the area, the reason and what remains unknown. (5) Follow-up scope: unanswered question, qualified specialist and agreed next step. Stay out of unsafe areas. Do not disturb materials. Leave entry decisions to a qualified professional. Label manufactured-home photographs by component so a ground-liner image is not mistaken for a completed belly repair.

Ask providers about the exact type of home

The Alabama directory includes Gulf Coast Foundations' Gulf Coast office and MDH Foundation Repair. Gulf Coast Foundations describes encapsulation and names Baldwin-area communities on its company website; MDH describes crawl-space repair and lists Baldwin County on its company website. Those descriptions provide starting points for separately defined moisture or repair inquiries. They do not verify manufactured-home installer certification, belly-repair experience or suitability for your particular home. State the home type before arranging a quote, ask whether the company accepts that work and verify any required credentials through the responsible authority. Directory inclusion is not an endorsement or a guarantee of coverage, availability or results.

Baldwin manufactured-home questions

Will a new ground liner fix a torn belly?

They are separate components. Ask the assessor to document each condition and specify what work is included at each location.

Can the county's ordinary repair permit answer every question?

No single assumption covers the whole scope. Confirm the parcel's authority, the county's manufactured-home exclusions and the commission's role for the proposed work.

Can skirting be installed as soon as the repair crew finishes?

First confirm the applicable inspection sequence. For the county's manufactured-home installation process, its final inspection occurs before skirting; an existing-home repair needs its own scope-specific answer. Sources checked October 15, 2026. HUD homeowner and provider pages include indexed-source review; the HUD-hosted moisture manual is an older technical publication, used for assembly concepts rather than current local code. Confirm current requirements with the responsible authority. No individual home inspection or provider installer-credential verification was performed for this guide.
