Big Sky country, big design loads
Montana covers everything from high mountain valleys to open plains, and the design loads change just as dramatically. A cabin near Big Sky may carry a roof snow load several times what a shop in Billings needs, a house in Livingston has to stand up to fierce Chinook winds, and western Montana sits in an active seismic belt. A PE stamp in Montana is only as good as the site-specific loads behind it.
PE Engineer prepares sealed drawings for homeowners, builders, ranchers and businesses across the state. Each set is sealed by a Professional Engineer licensed in Montana through our network of state-licensed PEs and prepared to the codes adopted by the State of Montana, with the snow, wind and seismic values for your exact location and elevation.
We design mountain homes and cabins, shops and post-frame buildings, ranch and equine facilities, resort-area remodels in Whitefish and Big Sky, commercial build-outs in Bozeman, Missoula and Billings, and equipment foundations for agricultural and energy operations in eastern Montana.
How licensing works. Engineering drawings must be sealed by a Professional Engineer licensed in Montana. 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 Montana. Their name and license number appear on the seal, exactly as your building department requires.

Montana's adopted building codes
Montana adopts building codes statewide through the Department of Labor and Industry’s Building Codes Program, based on the International Codes with Montana amendments. Cities and counties that have been certified by the state enforce the codes within their jurisdictions. Outside those areas, the state program typically handles permits for commercial and larger residential buildings, while rural single-family homes often need only state electrical and plumbing permits rather than a building permit. We design to the edition currently in effect.
- International Building Code (IBC) and International Residential Code (IRC) as adopted by Montana
- International Existing Building Code (IEBC)
- International Mechanical Code (IMC) and Uniform Plumbing Code (UPC) as adopted
- National Electrical Code (NFPA 70)
- International Energy Conservation Code (IECC) as adopted
- ASCE 7 for snow, wind and seismic loads
Snow, wind, seismic and wildfire design in Montana
Snow load is often the controlling design factor in Montana, and it depends heavily on elevation. Many mountain areas require the ground snow load to be determined for the specific site rather than read from a general map, and local building departments may publish their own values. Roof shape, drifts from adjacent roofs and sliding snow onto decks and lower roofs all matter. East of the Rockies, strong Chinook and downslope winds around places like Livingston and Great Falls call for careful uplift and lateral design, and open plains sites see high wind exposure.
Western Montana lies within the Intermountain Seismic Belt, and areas around Helena, Bozeman, Missoula and the Flathead see meaningfully higher seismic design values than the eastern plains. Wildfire risk is significant in forested valleys and foothills, where ignition-resistant materials and defensible space are worth planning from the start. Deep frost sets footing depth everywhere, and parts of eastern Montana have bentonite-rich expansive clays that need special foundation design.
How Montana permits work
If your property is inside a certified city or county jurisdiction, such as Bozeman, Missoula, Billings, Kalispell or Whitefish, the local building department reviews the plans and issues the permit. Outside those areas, the state Building Codes Program handles commercial permits, and the state also issues electrical and plumbing permits. Rural homeowners often find that a lender, insurer or covenant committee asks for sealed drawings even when no building permit is required.
- Confirm whether a local jurisdiction or the state has authority at your address.
- Submit sealed drawings, calculations and the permit application or lender package.
- We address review comments and revise within the original scope at no extra charge.
- Receive the permit and schedule inspections, or proceed with your lender’s requirements.
Subdivisions and resort communities often have their own design review as well, so we can coordinate drawings with architectural committee requirements before you submit for a permit.

PE stamp and permit FAQs for Montana
Can you provide a PE stamp for my project in Montana?
Yes. A Professional Engineer licensed in Montana from our network of state-licensed PEs reviews and seals every sheet and calculation. The drawings follow the codes Montana has adopted and state the ground snow load, wind speed and seismic values used for your specific site.
How do you determine the snow load for my mountain property?
We use your exact location and elevation along with the requirements of ASCE 7 and your local building department, which may publish its own values. Then we account for roof shape, drifting and sliding snow so every rafter, beam and connection is sized correctly.
Do I need a building permit for a home outside city limits?
It depends on where you are. Inside a certified local jurisdiction, yes. In many rural areas, single-family homes do not need a state building permit, though electrical and plumbing permits still apply. Lenders and insurers frequently require sealed drawings either way.
Can you design a shop or barn for high Montana winds?
Yes. We design post-frame, steel and wood shops, barns and arenas with uplift connections, bracing and large door openings detailed for the wind exposure at your site, plus snow loads for the roof. The sealed drawings work for permits, lenders and builders.
Do you work in Bozeman, Missoula and the Flathead Valley?
Yes. We prepare drawings for Bozeman, Big Sky, Missoula, Kalispell, Whitefish, Billings, Great Falls, Helena and rural counties statewide, with site-specific snow, wind and seismic loads for each project. Drawings are delivered electronically, so a remote ranch or resort property is no harder for us to serve than a city lot.
