Minnesota’s Real Snow Load, by County Tier
Unlike a home-rule state such as Colorado or Wyoming, Minnesota codifies its ground snow load directly in Minnesota Rules, Part 1303.1700 — a clean two-tier structure rather than a county-by-county patchwork:
| Region | Ground Snow Load (Pg) |
|---|---|
| 29 named northern & northeastern counties (St. Louis, Cook, Lake, Itasca, Beltrami, Otter Tail, and 23 others) | 60 psf |
| Every other Minnesota county | 50 psf |
Source: Minnesota Rules, Part 1303.1700 (“Ground Snow Load”), Minnesota Department of Labor and Industry, as published by the Minnesota Office of the Revisor of Statutes.
Both tiers already clear Northcraft’s standard basis. Northcraft’s published floor prices assume ground snow load up to 35 psf — both Minnesota tiers, 50 psf and 60 psf, sit above that threshold, so plan on the snow-load factor applying to essentially every Minnesota site, not just the 29 northern counties.
Wind is close to uniform statewide. The Minnesota Residential Code sets an ultimate design wind speed of 115 mph for Risk Category II construction across the state — already above Northcraft’s 110 mph published basis threshold everywhere in Minnesota, not just in a specific corridor.
Seismic risk is genuinely low. Minnesota is rated Seismic Design Category A statewide — the lowest classification under the code — so unlike a Rocky Mountain or intermountain state, seismic load is rarely the driver of a Minnesota project’s final engineered price.
Minnesota’s Code and Permitting Reality
Minnesota enforces a genuinely centralized statewide building code, unlike the home-rule patchwork common in many Rocky Mountain states. The currently effective 2020 Minnesota State Building Code, based on the 2018 IBC (commercial construction) and 2018 IRC (residential construction), took effect March 31, 2020, and applies uniformly across the state. The Department of Labor and Industry was working through rulemaking toward a 2024-IBC-based update at the time this page was researched — confirm the currently adopted edition before finalizing engineering.
Even with a state-owned code, permitting itself stays local: a certified building official at your city or county reviews plans, issues the permit, and performs inspections under the statewide rules.
Most jurisdictions require a permit, issued locally, and your local building department confirms the exact snow-load tier and wind figure that apply to your specific parcel before you can finalize engineering — exactly why Northcraft asks for your county rather than publishing a single Minnesota price.
What a Steel Building Costs in Minnesota
Starting at $10,500
Northcraft’s starting price, 20x24 in C-channel framing, 10’ eave height basis, at Northcraft’s standard 35 psf snow / 110 mph wind basis. Larger sizes up to 50x100 in I-beam are quoted per size — tell us your footprint and we’ll confirm your number.
What moves the price for a Minnesota site
- • Eave height above the published basis
- • Ground snow load above 35 psf — true statewide, both Minnesota tiers (50 and 60 psf) clear Northcraft's 35 psf basis
- • Wind load above 110 mph — true statewide, Minnesota's 115 mph design figure clears Northcraft's 110 mph basis everywhere
- • Areas with high seismic activity — not typically a factor; Minnesota is rated Seismic Design Category A statewide
- • Collateral load requirements (I-beam buildings only)
This is a starting range for the structural shell, not a binding quote. See the size pages below for exact floors, and tell us your Minnesota county for your real engineered number.
What Minnesota Builds
Northern & Arrowhead Agricultural and Storage
Duluth, the Iron Range, and the 29 counties carrying Minnesota's 60 psf northern-tier snow load see real demand for machinery sheds, hay storage, and cold-storage buildings sized for that heavier load.
Twin Cities Metro Residential & Workshop
The Minneapolis-St. Paul metro and southern Minnesota fall under the state's 50 psf standard tier — barndominiums, garages, and workshops here are engineered to the more common of Minnesota's two published figures.
Statewide Commercial & Warehouse
Minnesota's uniform 115 mph design wind speed and Seismic Design Category A hold across nearly the entire state, which makes commercial and warehouse planning here more predictable than in an elevation-driven state like Colorado or Wyoming.

Frequently Asked Questions
What ground snow load do I need to design for in Minnesota?
Minnesota is one of the few states with a clean, codified statewide rule rather than a county-by-county patchwork. Under Minnesota Rules, Part 1303.1700, ground snow load is 60 psf in 29 named northern and northeastern counties — including St. Louis, Cook, Lake, Itasca, Beltrami, and Otter Tail — and 50 psf everywhere else in the state. Tell us your county and we'll confirm which tier applies to your site.
Which Minnesota counties carry the higher 60 psf snow load?
Twenty-nine counties, mostly across the northern half of the state: Aitkin, Becker, Beltrami, Carlton, Cass, Clearwater, Cook, Crow Wing, Hubbard, Itasca, Kanabec, Kittson, Koochiching, Lake, Lake of the Woods, Mahnomen, Marshall, Mille Lacs, Morrison, Norman, Otter Tail, Pennington, Pine, Polk, Red Lake, Roseau, St. Louis, Todd, Wadena. Every other Minnesota county designs to the standard 50 psf figure under the same rule.
Does Minnesota use the same wind speed everywhere?
Minnesota's design wind speed is materially more uniform than its snow load. The Minnesota Residential Code sets an ultimate design wind speed of 115 mph statewide for Risk Category II construction — a single figure that already clears Northcraft's 110 mph published basis threshold everywhere in the state.
Does Minnesota have one statewide building code?
Yes, and this is a real difference from a home-rule state like Colorado or Wyoming. Minnesota has enforced a genuinely centralized state building code since well before the current edition — the 2020 Minnesota State Building Code (based on the 2018 IBC for commercial construction and the 2018 IRC for residential, effective March 31, 2020) applies statewide. The Department of Labor and Industry owns the code; a further update based on the 2024 IBC was in active rulemaking as of this page's last review, so confirm the current edition before finalizing engineering.
Who issues my building permit in Minnesota?
The state owns and adopts the code itself, but permits are still applied for and issued locally — a certified building official at your city or county administers plan review, permitting, and inspection under the statewide rules, not a separate local code.
Is seismic activity a real factor in Minnesota?
No — Minnesota is rated Seismic Design Category A statewide under the Minnesota Residential Code, the lowest classification, meaning seismic provisions generally don't apply to construction here. Of Northcraft's five "what moves the price" factors, seismic load is not typically a driver for a Minnesota site the way it can be in a Rocky Mountain state.
What does a steel building cost in Minnesota?
Northcraft's published floors start at $10,500 for a 20x24, scaling up in size through 40x100 in C-channel framing and 50x100 in I-beam. Those floors assume ground snow load up to 35 psf and wind up to 110 mph — both Minnesota snow tiers (50 and 60 psf) and the statewide 115 mph wind figure clear that basis, so plan on the snow-load and wind-load factors applying to nearly every Minnesota site. Tell us your county and we'll confirm your real engineered number.
Do I need a permit for a steel building in Minnesota?
Most jurisdictions require a permit. Minnesota's statewide code is administered locally, so your city or county building department issues the permit and confirms the exact snow-load tier and wind figure for your parcel. We provide the stamped engineering drawings that process requires.
How long does delivery take to a Minnesota site?
Typically 45-60 days from order to delivery, depending on engineering review and current production volume, plus normal freight time to your site. Your estimator confirms a real date range once your drawings are finalized.
