The foundation and site work are part of the building project, not details to guess at after choosing a package. Requirements depend on the specific building, framing system, site, intended use, local conditions, and jurisdiction. This guide is a question list for conversations with providers and qualified design professionals; it is not foundation or engineering advice.
Start with the local process
Contact the building department or other authority that serves the property. Ask which office handles zoning, building permits, site plans, inspections, and any drainage or utility review. The International Code Council’s 2024 IRC administration chapter describes permit procedures and review of construction documents; the adopted code and local amendments depend on the jurisdiction and project.
Ask the provider what documents it can supply, what it expects you to obtain, and who coordinates engineering questions. A kit or package may not include site preparation, foundation work, permit applications, or installation.
Share what you know about the property
Before requesting proposals, gather any survey or site plan you already have and note:
- The likely building location and nearby structures or property lines.
- How trucks and equipment can reach the site.
- Visible slope, drainage paths, or areas that hold water.
- Existing driveways, utilities, trees, or other constraints.
- Whether the site has been cleared or graded.
- Any soil or geotechnical information already available.
These notes do not determine whether the site is suitable. They help the provider identify what it needs to evaluate.
Ask who is responsible for each part
Clarify responsibilities for site preparation, excavation, foundation design, slab or post foundation work, materials, installation, inspections, and restoration. If different companies perform the package, foundation, and erection, confirm how design details are coordinated.
For post-frame construction, the National Frame Building Association maintains technical resources on post-frame design and foundations. These resources are designed for professionals. They underscore why a homeowner should ask who is responsible for the project-specific foundation design rather than copy a generic detail.
Discuss location-specific design conditions
Tell the provider where the building will be located and how it will be used. Ask what local design conditions and site information it needs to consider, including applicable wind or snow criteria, drainage, soils, and building occupancy. FEMA’s Snow Load Safety Guide describes several conditions that influence snow-load design. It is a technical reference, not a tool for choosing structural specifications yourself.
Avoid choosing a foundation based only on a neighbor’s building, a general online chart, or a standard package description. Confirm the proposal with qualified professionals and the local authority where required.
Foundation and site-prep questions to bring
- What site information do you need before finalizing the building design?
- Who is responsible for foundation design and construction documents?
- What foundation or slab work is included in the proposal, if any?
- Who handles clearing, grading, drainage, access, and excavation?
- Are survey, soils, or geotechnical documents required for this project?
- How will the building system connect to its foundation?
- What local permit or inspection steps should I confirm?
- Which parts of the work are assigned to me or another contractor?
- How will the provider coordinate design updates if site conditions change?
Write down the answers and who gave them. If two providers describe different assumptions, ask each to clarify before you compare proposals.
