Metal buildings for projects across Missouri
We supply shops, farm buildings, barndominium shells, commercial buildings and more across Missouri. Our work reaches from Springfield and the Ozarks to the Kansas City and St. Louis metros, and anywhere else you’re building.
Statewide building code

Site-specific
Every city and county sets its own rules. We confirm yours before drawings are produced.
What matters when building in Missouri?
A hay barn on county ground and a finished workshop inside city limits a few miles away can face very different requirements at the same size.
No statewide code
Each city and county decides whether to adopt one, and which edition.
Code edition
Editions in force vary by decades in places, and the loads change with them.
How it’s used
Farm storage and occupied space fall under different engineering standards.
Southeast Missouri
The New Madrid seismic zone changes anchorage and bracing.
Where you build changes the rules
With no statewide code, the model code isn’t a safe guide. Here’s how Missouri’s cities and counties usually break down.
Cities
- Springfield permits accessory buildings over 100 sq ft.
- Bolivar permits buildings at any size.
- Most permitted city work calls for site-specific drawings.
Rural counties
- Unincorporated Polk and Webster have no building code and don’t permit.
- Greene, Christian and most rural counties accept generic Risk Category I for ag and utility buildings.
- Our generic packages are wet-sealed.
The exceptions
- Cass County doesn’t accept generic tubular engineering at any risk category.
- Statewide code bills have been introduced, but none is law.
Occupied buildings are Risk Category II and need engineering to that standard wherever they sit, whatever the county requires.
What usually fits which project
We start with what you’re building and work back to the structural system. Here’s where that usually lands.
Shops & storage
Tubular steel fits up to sixty feet wide. Red iron takes over past eighty feet, or for big doors and heavy loads.
Heated shop
It’s still tubular under sixty feet. Insulation costs the same per square foot whatever the frame is.
Drywalled shop or barndominium
Steel truss is the fit here. Drywall screws straight to the frame, so there’s no wood wall to build inside the steel.
Commercial & wide spans
Cold-formed suits permitted commercial work with a finished eave. Red iron takes over past eighty feet.
Where your city or county requires site-specific engineering, the math can shift. See what a steel building costs for real per-square-foot ranges.
Local guides for Missouri
We deliver and install anywhere in Missouri. These guides cover the permit rules around the state’s larger towns, and we check the rules for every other address the same way.

Common questions about building in Missouri
Do I need a permit for a metal building in Missouri?
It depends on your city or county. Springfield requires a permit for accessory structures over 100 square feet. Bolivar requires one regardless of size. Unincorporated Polk and Webster counties have adopted no building code and don’t permit at all. Statewide code bills have been introduced, but none is law today.
What building code does Missouri use?
There’s no statewide code. Jurisdictions that enforce one adopt their own edition of the IBC or IRC, and editions vary by decades in places. The edition determines which version of ASCE 7 your loads come from, so we confirm it before drawings are produced.
What snow and wind loads does a Missouri building have to be designed for?
Ground snow generally falls between 15 and 25 psf, lighter in the southern Ozarks and heavier north of the Missouri River. Design wind generally runs 105 to 115 mph for a Risk Category II building. Southeast Missouri’s New Madrid seismic zone raises the seismic design category. We run the ASCE 7 hazard tool against your address and design to what it returns.
Is generic engineering enough, or do I need site-specific engineering?
Greene, Christian, Polk and most rural counties accept wet-sealed generic Risk Category I engineering for ag and utility buildings. Cass County doesn’t accept generic tubular engineering at any risk category. Where site-specific engineering is required, it runs roughly $2.00/sq ft on tubular against $0.75 on cold-formed, about $3,000 on a 40×60.
On an unfinished shop, tubular still wins. Where the gap was already small, it can change the recommendation. If you’ll finish it as living space, steel truss is usually the answer anyway.
What sizes are most common in Missouri?
Sizes of 30×40, 30×50, 40×60 and 40×80 cover most of what goes up here. See what a steel building costs, or call and we’ll put an actual number on your building.
