Why buy barndominium plans for Illinois from us
A barndominium puts your home and your shop under one roof, which saves on foundations, roofing and site work compared with two buildings.
We draw steel-frame, wood-frame and post-frame barndos with frame lines shown for your metal building supplier, so your builder and steel vendor work from the same drawings.
Shops and RV bays
14-foot doors, wash bays, 50-amp service and floor drains are all shown on the plans.
Any framing system
Steel, wood or post-frame, and we can draw it so either works with small changes.
Complete, not just a shell
Interior layout, electrical and foundation details that kit plans often leave out.
What's included in your barndominium plans
- Living area and shop on one coordinated plan
- Shop bays, RV bays and overhead door sizes
- Steel or post-frame lines for your supplier
- Loft, mezzanine and guest suite options
- Porches, mudroom and safe room options

Building requirements
Building a house in Illinois, IL: what the code requires
Codes adopted locally (no mandatory statewide code)
- Building code
- No statewide residential building code outside certain requirements. Municipalities adopt codes (usually an IRC edition), and Chicago has its own Chicago Building Code.
- Energy code
- The Illinois Energy Conservation Code (IECC-based) applies statewide to new residential construction.
- Climate zone
- IECC climate zone 4–5. Insulation, windows and HVAC are sized to match.
- Typical frost depth
- 32–42 in. Footings must extend below the local frost line (confirm with your building department).
- Foundations
- Crawlspace or basement, depending on soil and lot slope.
- Who can draw the plans
- Single-family homes can generally be designed by a non-licensed home designer. A licensed engineer's stamp is often required for structural items, engineered foundations or special hazard zones, or when the local building official asks for it.
- Engineer stamp
- If your jurisdiction requires sealed drawings, add our Illinois Engineer Stamp / Permit-Ready package ($750).
Illinois-specific rules & hazards
- Chicago generally requires permit drawings sealed by an Illinois-licensed architect or engineer.
- Many unincorporated county areas have limited building code enforcement.
- Heavy roof snow loads and steeper, well-braced roof framing
- Tornado-resistant framing, with safe-room options
Summary for planning only. Codes, editions and local amendments change, so always confirm current requirements with the building department that will issue your permit. Our designers check your jurisdiction before drawing.
