Colorado drawings built for snow, soils and local review
If you need a PE stamp in Colorado, the first thing to know is that design loads change dramatically with elevation. A deck in Denver, a garage in Colorado Springs and a home in Breckenridge or Steamboat Springs can carry very different ground snow loads, and building departments in mountain counties publish their own snow and wind criteria. Colorado has no single statewide building code for most private construction, so each city and county adopts and amends the International Codes on its own schedule.
PE Engineer prepares structural, architectural, MEP and civil drawings for Colorado projects, sealed by a Colorado-licensed Professional Engineer through our network of state-licensed PEs. We pull the local design criteria for your address, including snow, wind, frost depth and soils requirements, before we size a single member.
Front Range requests often involve basement finishes, structural floor systems over expansive soils, decks, ADUs and additions. Mountain and Western Slope projects lean toward new homes on steep lots, retaining walls, snow-load upgrades and steel or post-frame buildings for equipment and ranch use.
How licensing works. Engineering drawings must be sealed by a Professional Engineer licensed in Colorado. PE Engineer works with a network of state-licensed PEs, so every set is reviewed and stamped by an engineer with an active license in Colorado. Their name and license number appear on the seal, exactly as your building department requires.

Colorado building codes and local amendments
Colorado leaves building code adoption to local governments. Denver, Aurora, Boulder, the Pikes Peak Regional Building Department serving Colorado Springs and El Paso County, and most other jurisdictions adopt the International Codes with local amendments, and mountain counties often publish their own snow load and wind tables. The state adopts plumbing and electrical codes and sets minimum energy code requirements that local governments must meet when they update. We design to whatever your jurisdiction currently enforces.
- International Building Code (IBC) with local amendments
- International Residential Code (IRC) with local amendments
- International Energy Conservation Code (IECC) as adopted locally, with state minimums
- Colorado Plumbing Code, based on the IPC
- NEC/NFPA 70 as adopted by the state
- ASCE 7 with local snow and wind criteria
Snow, wind and expansive soils in Colorado
Snow is the defining structural load across much of Colorado. Ground snow loads rise quickly with elevation, and in many mountain towns roofs must also handle drifting, sliding snow and rain-on-snow surcharges. Front Range communities near the foothills, including parts of Boulder and Jefferson counties, also see severe downslope windstorms, and some jurisdictions there require higher design wind speeds than the national maps alone would suggest. Hail is common on the eastern plains.
Expansive soils are the other big Colorado issue. Bentonite clays and claystone bedrock along the Front Range can swell significantly when wet, lifting slabs and foundations. Builders often rely on structural floors over crawlspaces, drilled piers with void forms and careful drainage. Wildfire is a growing concern in foothill and mountain areas, and many counties enforce wildland-urban interface requirements. Frost depths are set locally and vary with elevation, and seismic design values are generally low to moderate.
How the permit process works in Colorado
Colorado permit offices range from large urban departments with online portals, such as Denver and Pikes Peak Regional, to small county offices in the mountains that still review plans in person. Many mountain jurisdictions require a soils report and a site-specific snow load, and some HOAs and design review boards add their own architectural approvals.
- Confirm the jurisdiction, design criteria and whether a soils report is required.
- We prepare drawings and calculations, sealed by a Colorado-licensed PE.
- The plans examiner reviews the set and issues comments.
- We respond, revise within the original scope and reseal the set until approval.
Mountain construction seasons are short. Submitting a complete set early in the year makes it far more likely that framing starts before the first snow.

PE stamp and permit FAQs for Colorado
Can you provide a PE stamp for my project in Colorado?
Yes. Colorado projects are sealed by a Professional Engineer licensed in Colorado through PE Engineer’s network of state-licensed PEs. The engineer reviews the design against your local criteria for snow, wind and soils, and the seal shows their name and Colorado license number for the building department to verify.
What is a structural floor and do I need one?
A structural floor is a framed floor system that spans over a crawlspace instead of resting on the soil, so expansive clay can swell without lifting it. Many Front Range jurisdictions and soils engineers recommend or require one when the soils report shows high swell potential. We design the framing, beams and pier connections to match the report.
How do you determine snow load for a mountain property?
We start with the ground snow load your county or town publishes for your elevation and location, then apply ASCE 7 factors for exposure, roof slope, thermal conditions, drifting and sliding snow. Mountain jurisdictions often set values well above broad state maps, so local criteria always come first in our calculations.
Can you design a deck or ADU in Denver?
Yes. We prepare deck framing plans and ADU permit sets for Denver and surrounding Front Range cities, including footings sized for local frost depth, ledger and guard connections, floor plans, elevations, energy documentation and site plans. We follow the city’s current zoning and code requirements for accessory dwellings.
Do I need a soils report in Colorado?
For new homes and many additions, usually yes. Most Colorado jurisdictions require a geotechnical report because expansive soils are widespread. For smaller projects such as decks or porches, some departments accept conservative design values instead. We tell you what your jurisdiction expects and design the foundation around the report recommendations.
