Building requirements
Building a house in Colorado Springs, CO: what the code requires
Codes adopted locally (no mandatory statewide code)
- Building code
- No statewide residential code. Counties and cities adopt IRC editions with amendments (Denver has its own Denver Building Code).
- Energy code
- State law requires jurisdictions that update codes to adopt a recent IECC edition plus electric- and solar-ready provisions.
- Climate zone
- IECC climate zone 4–7. Insulation, windows and HVAC are sized to match.
- Typical frost depth
- 30–36 in (Front Range), 36–48 in+ (mountains). 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 Colorado Engineer Stamp / Permit-Ready package ($750).
Colorado-specific rules & hazards
- Mountain counties commonly require engineered foundations, high snow loads (often 50–100+ psf) and wildfire mitigation.
- Expansive soils along the Front Range often require a soils report and engineered foundation.
- Heavy roof snow loads and steeper, well-braced roof framing
- Wildfire-resistant materials and defensible-space detailing
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.
