Installation Support Systems
Foundation and anchoring terms for a mobile home are easy to blur together. A homeowner does not need field instructions, but does need to know what each term is trying to accomplish, which document controls it, and which party owns the written scope — and the installation manual and the county's paperwork will both say manufactured home.
Short answer: Footings or other approved bases transfer loads to the site; piers and approved support components carry the home; blocking, caps, or shims may be parts of the documented support assembly; and anchors, straps, or an approved alternate system resist movement. The manufacturer’s instructions or an approved design, the actual site, and the responsible authority determine what applies.

Buying land for a mobile home? The Land Check reads the county's own permit rules for the one parcel you give us, and says where each answer came from and when.
$125. Asking takes no payment and places no order.
Start with the exact property, quote, record, or job detail behind your question. Mark what is confirmed, what still needs a current source, and who must answer it. Use the checklist to keep the next call, document, or decision clear.
Start with the home’s installation instructions or the approved project-specific design, not a generic diagram or material list.
Separate site and footing work, masonry work, home setup and anchoring, engineering, and inspection responsibilities in writing.
Use qualified providers and the responsible authority for field decisions; this guide does not size, space, select, install, or approve components.
Step 1
Collect the home information, installation instructions, approved plans, site information, permit record, and written dealer or contractor scopes.
Step 2
Mark each line item as site preparation, footing or masonry work, setup and support, anchoring, engineering, inspection, or homeowner coordination.
Step 3
Ask the responsible provider and authority which document controls the actual work and what must remain visible or documented for review.
Details to Sort
These terms concern the approved bearing surface or site-built work below the home. A pad or slab description does not by itself establish the complete support, anchoring, drainage, frost, soil, or permanent-foundation path. Ask what the approved documents call the work, who builds it, and what site information controls it.
These words can describe parts of the vertical support assembly between the approved base and the home. The setup contractor normally follows the applicable installation instructions or approved design. A mason may build defined concrete or block work, but does not automatically own home placement, leveling, anchoring, or engineering.
Anchoring and stabilization resist wind or other movement through the documented system for the home and site. The installer should identify the controlling instructions and written responsibility. An engineer addresses design or evaluation only within the engineer’s retained scope; the homeowner should not choose spacing, hardware, or substitutions from general guidance.
The retailer should provide the home and package documents and state what is included. The setup contractor handles the home-installation scope in the written agreement. A mason handles defined masonry or concrete work. An engineer handles retained design, evaluation, or certification work. The homeowner preserves documents, confirms responsibilities, and coordinates access and review dates.
Have the home manufacturer, model, serial or section information, dimensions, installation instructions, approved plans, site plan or survey, soil or bearing information if requested, grading and drainage status, permit and inspection contacts, lender requirements, and every written quote or exclusion.
Home size and section count, site access, elevations, soil or bearing information, excavation, concrete or masonry quantities, approved support and anchoring path, drainage, engineering, inspection access, weather, sequencing, and correction responsibility can affect cost. Compare the same documented scope rather than component names alone.
Ask which document controls; who supplies each material; who handles excavation, concrete or masonry, setup, leveling, anchoring, utility penetrations, engineering, and inspections; what remains visible; what changes require written review; and what evidence closes each party’s scope.
Qualified Service Request (QSR)
Use the private need-and-ZIP request after the controlling documents and responsibility are clear. My Manufactured Home Guide does not display availability, select a design, or assign a provider.
Secondary Support
Tell us the work and your ZIP and we send you to the right contractor category page, where you send the request. No account needed.
The instructions may define the support and anchoring system for that home, but the site, local process, and written provider scopes still have to align.
Next step: Ask the setup contractor which pages control the work and which site, masonry, trade, and inspection tasks are excluded.
An alternate or project-specific path can require qualified design, manufacturer-program, lender, insurer, or authority review depending on the project.
Next step: Ask who prepares, seals, accepts, installs, and inspects the design; do not substitute a generic online detail.
A financing-related foundation certification is a separate, site-specific professional document question. It is not created by adding block skirting or by calling a setup quote a permanent foundation.
Next step: Ask the lender exactly what standard and document it requires, then ask a North Carolina-licensed engineer or architect what records and site access are needed.
Not necessarily. Footings or other approved bases concern bearing at the site, while piers and other support components carry loads between that base and the home. Use the project’s controlling documents for the actual definitions and assembly.
The applicable manufacturer-approved installation instructions or approved project-specific design control the system. The qualified installer follows that path, and the responsible authority or inspector reviews within its role. An engineer may be needed for a retained design or evaluation scope.
No automatic conclusion is safe. A masonry curtain wall or block enclosure may be non-structural. Ask what the approved foundation documents show and what a lender, insurer, appraiser, engineer, or authority actually requires.
No. This page is for terminology, document, responsibility, and quote questions. Installation, adjustment, repair, structural evaluation, and approval require qualified parties working from the actual home and site documents.
