Why Steel Works in Mississippi
Steel buildings hold up in Mississippi when the frame is engineered for its own site. We are a dealer of pre-engineered steel building kits from American steel, and our metal buildings in Mississippi arrive with PE-stamped drawings for the parcel.
Wind from the Gulf comes first. In 2005 Hurricane Katrina pushed a storm surge of 24 to 28 feet onto a stretch of the Mississippi coast centered on St. Louis Bay, and the next year the state required its five coastal counties to enforce the wind and flood provisions of the building codes. Our guide to steel buildings in coastal and hurricane zones explains how frames and anchors carry that load.
Inland, the threat is tornadoes. Mississippi averaged about 33 a year in 1950–2020, with the peak from March through May, and in March 2023 an EF4 tornado struck Rolling Fork in the Delta. Rain averages about 56 inches a year, from 50 in the north to about 65 on the coast, so closed buildings need vapor control and drainage around the slab. The drawings carry the design wind speed, risk category and exposure category for the parcel.
Opt-out rules, flood maps and the farm exemption are in the codes and permits section below.
Mississippi at a Glance
What We Engineer for:
Design wind speed and exposure category set for your parcel under ASCE 7; Hancock, Harrison, Jackson, Pearl River and Stone counties enforce wind and flood provisions
About 33 a year on average in 1950–2020, with the peak from March through May; anchors and connections follow the anchor bolt layout on the drawings
Check the FEMA map for your parcel; a farm building exempt from the county code can still need a flood permit
About 56 inches a year statewide and near 65 on the coast; vapor barriers and ventilation keep condensation off the panels
A state council approves the model codes; counties and cities enforce them unless they opted out in 2014, and the five coastal counties are required to
Building Codes and Permits in Mississippi
The Mississippi Building Codes Council approves statewide codes based on the International Codes. A 2014 state law required counties and cities to enforce them, but each could opt out by resolution that year, and many counties did. The five coastal counties are required to enforce the code. Drawings are prepared to the edition your jurisdiction enforces; your building department is the authoritative source.
Inside city limits, start with the city building department. In the county, ask the board of supervisors or the county building office whether a code covers your parcel; some counties have none. We don’t pull the permit; we supply PE-stamped drawings, load calculations and specifications.
State law exempts farm structures from county and city building codes: barns, sheds, poultry houses and other buildings used on the farm. A home, or a building attached to one, does not qualify. The owner files an affidavit stating the building’s intended use with the code official before construction starts, and a farm building later converted to another use loses the exemption. Federal flood rules still apply, so an exempt barn in a flood zone can need a flood permit. A private hunting or fishing camp in the county qualifies the same way, by affidavit to the board of supervisors.
On the coast, wind and water set the frame. Hancock, Harrison, Jackson, Pearl River and Stone counties enforce wind and flood provisions adopted after Katrina, and your drawings carry the design wind speed and exposure category for the lot. Footing depth follows your soil and the local code; a local contractor pours the footings to our anchor bolt layout. Check flood risk on the FEMA Flood Map Service Center and with your county.

Steel Buildings We Deliver Across Mississippi
What a Steel Building Costs in Mississippi
The price of a steel building in Mississippi depends on its size, the loads of its site and its finish. Coastal wind adds frame weight and anchors.
From 20×20 to 30×40: garages, carports with storage and hunting camp sheds.
From 30×50 to 40×80: shops, steel homes, equipment barns and small offices.
From 50×100 up: warehouses, commercial buildings and farm storage.
A 40×60 on an open lot in Harrison County, facing the Mississippi Sound, gets a heavier frame and more anchors than the same building on a sheltered lot in the north Mississippi hills, because design wind speed and exposure rise toward the Gulf.
The $ tier covers the kit itself: frame, roof and wall panels. Insulation, overhead doors and liner panels move it to $$, and a finished living space or office inside to $$$. Our metal building cost guide lists dollar ranges by size, and our guide to what it costs to build a barndominium covers homes.

How Mississippi Owners Use Steel Buildings by Region
The Delta (Greenville, Greenwood, Clarksdale, Cleveland, Rolling Fork; Washington, Leflore, Coahoma, Bolivar, Sunflower, Sharkey counties)
The Delta is flat, fertile row-crop and fish-farm country. Mississippi ranked first in the nation for foodsize catfish inventory in July 2024, and Leflore and Sunflower counties are among its top catfish counties. The March 2023 tornado at Rolling Fork crossed this plain, so anchors matter here too. Combines and cotton pickers need tall, wide doors; see our tractor barns.

North Mississippi Hills (Tupelo, Oxford, Southaven, Columbus, Amory; Lee, Lafayette, DeSoto, Lowndes, Monroe counties)
North Mississippi mixes cattle and hay farms with the suburbs of Memphis, which spill into DeSoto County. Families there and around Oxford and Tupelo add garages, shops and steel homes on acreage. The same March 2023 storms sent an EF3 tornado through Amory, and rain is lightest here, about 50 inches a year. See our residential metal buildings.
See also: RV garages · Livestock barns
Central Mississippi and the Pine Belt (Jackson, Meridian, Hattiesburg, Laurel; Hinds, Madison, Rankin, Lauderdale, Forrest, Jones counties)
Central Mississippi is the capital region and poultry and timber country. Poultry is Mississippi’s top farm commodity and forestry ranks second, and Jones County, around Laurel, ranks fourth in the state for poultry and egg sales. Businesses around Jackson and Meridian build shops, showrooms and offices; start with our metal office buildings.

Gulf Coast (Gulfport, Biloxi, Bay St. Louis, Pascagoula, Picayune; Harrison, Hancock, Jackson, Pearl River, Stone counties)
The coast is hurricane country first. Katrina’s highest surge mark, 27.8 feet, was measured at Pass Christian, and rain here averages about 65 inches a year, the most in the state. Contractors and marinas need closed, well-drained storage near the water; see our metal warehouses.

Design Your Building NowFrequently Asked Questions
Yes, but not every county enforces it. The Mississippi Building Codes Council approves statewide codes based on the International Codes; a 2014 law let counties and cities opt out that year, and many did, while the five coastal counties are required to enforce them. Your building department has the final word on the edition.
Usually not for the building code, if the barn is a farm structure. State law exempts barns, sheds and poultry houses used on the farm once the owner files an affidavit of intended use before construction. A home or a building attached to one is not exempt, and a flood permit can still apply in a flood zone.
They are engineered for the design wind speed and exposure category of the exact site under ASCE 7, and the design wind speed rises toward the Gulf. A lot in Hancock, Harrison or Jackson County carries a higher load than one near Tupelo. Your building official confirms the figures, so send the full address with your quote request.
Yes, we deliver across Mississippi, from Southaven to Hattiesburg and Gulfport. Make sure a truck can reach the pad. We confirm your production schedule and delivery window when your order is finalized. Your crew or a local erector assembles the building; if you want installation arranged, ask when you request your quote.
Yes. Shops, offices, showrooms and warehouses come as pre-engineered steel building kits drawn for your site’s wind loads. They fall under the code your city or county enforces, so plan review starts there. Tell us the use, size and door layout with your quote request.
