Utah’s diverse landscape—ranging from the high peaks of the Wasatch Front to the arid deserts of the south—presents a unique set of challenges for construction. Steel buildings are an incredibly popular choice across the state due to their durability and speed of assembly, but they aren’t immune to local pitfalls.
Whether you are erecting a commercial warehouse in Salt Lake City or an agricultural barn in St. George, failing to account for Utah’s specific environmental and regulatory conditions can lead to costly delays or structural failures.
If you are planning a steel construction project in the Beehive State, avoiding these seven common mistakes will help ensure your building stands strong for decades to come.
1. Underestimating Utah’s Heavy Snow Loads
One of the most frequent—and dangerous—oversights in Utah construction is underestimating the weight of snow. Unlike states with relatively uniform weather, Utah’s topography creates massive variations in snow load requirements within short distances.
While a building in St. George might only require a minimal snow load design, a structure just a few hours north in Park City or up Big Cottonwood Canyon faces significantly higher demands.
The Code Requirement
According to the Salt Lake City Design Criteria, ground snow loads vary by elevation. For projects at or below 4,239 feet, the ground snow load must be a minimum of 28 pounds per square foot (psf). However, once you go above that elevation, the requirements skyrocket.
The Solution
- Don’t guess. Never assume a “standard” snow load.
- Check the Elevation: Use the Utah State University snow load calculator or consult the specific county building department.
- Account for “Drift”: If your steel building has multiple roof levels or is adjacent to another structure, snow will pile up against walls (snow drift), creating intense localized weight that can buckle steel purlins if not engineered correctly.
2. Ignoring Seismic Activity Zones
Utah is earthquake country. The Wasatch Fault runs through the heart of the state’s most populous region, placing many construction projects in high-risk seismic zones.
Many first-time builders assume that because steel is ductile (flexible), it is automatically earthquake-proof. While steel performs better than unreinforced masonry, it still requires specific engineering to handle the lateral forces generated during a seismic event.
The Code Requirement
Salt Lake City and surrounding areas typically fall into Seismic Design Category D or D2. This classification dictates specific connection details and bracing requirements in your steel frame.
The Solution
Ensure your structural engineer uses the correct Spectral Response Acceleration parameters for your specific site address. A “generic” Utah engineering package might not meet the strict seismic bracing requirements of the Wasatch Front.
3. Neglecting the Frost Depth for Foundations
Steel buildings are relatively lightweight, which sometimes leads builders to skimp on the foundation. In Utah, this is a major error due to the freeze-thaw cycle. If your foundation footing does not extend below the frost line, the ground moisture will freeze, expand, and “heave” your building upward, cracking the concrete and twisting the steel frame.
The Code Requirement
In Salt Lake City and many northern Utah jurisdictions, the required frost depth is 30 inches. This means the bottom of your concrete footing must be at least 30 inches below the finished grade.
The Solution
- Verify Local Depth: While 30 inches is standard in the valley, higher elevations may require 36 or 48 inches.
- Insulate Properly: For shallow frost-protected foundations (an alternative to deep footings), specific insulation details are required by the International Residential Code (IRC) or International Building Code (IBC).
4. Failing to Verify Contractor Licensing
Utah has strict laws regarding who can legally erect steel buildings. A common mistake is hiring a “handyman” or an unlicensed crew to assemble the kit to save money. This poses significant liability risks and can halt your project if a building inspector asks for the contractor’s credentials.
The Requirement
In Utah, contractors must be licensed by the Division of Professional Licensing (DOPL). For steel buildings, you typically need a contractor with a B100 (General Building) or S350 (HVAC/Steel Erection) classification, depending on the scope.
The Solution
- Verify the License: Before signing a contract, check the contractor’s status on the Utah DOPL Licensee Lookup & Verification System.
- Check Insurance: Ensure they carry valid general liability and workers’ compensation insurance. As the property owner, you could be liable for injuries that happen on your site if the crew is uninsured.
5. Overlooking Condensation Control
Steel conducts heat efficiently, which is a disadvantage in Utah’s climate. In the winter, the warm air inside your building will hit the cold steel sheeting. Without a thermal break, this temperature difference causes condensation to form on the underside of the roof.
We frequently see steel buildings in Utah that “rain” inside during the winter, damaging inventory, insulation, and machinery.
The Solution
- Install a Vapor Barrier: A high-quality reinforced vinyl back fiberglass insulation (often called “bag and sag”) acts as both insulation and a vapor barrier.
- Ventilation: Ensure the building has adequate ridge vents and louvers to allow moist air to escape before it condenses.
6. Using Outdated Building Codes
Utah periodically updates its adopted building codes. Designing a building based on old standards will result in permit rejection, forcing you to pay for expensive re-engineering.
The Current Standard
As of July 1, 2024, the state of Utah has adopted the 2021 International Building Code (IBC) and the 2021 International Energy Conservation Code (IECC), with specific statewide amendments.
The Solution
Ensure your steel building manufacturer is designing to the 2021 IBC/IECC standards. If you purchase a clearance building or a kit from a supplier who hasn’t updated their software, the plans may be rejected by your local building department.
7. Skipping the Geotechnical (Soils) Report
Finally, one of the most expensive mistakes is building on “problem soil” without knowing it. Parts of Utah (especially around Utah Lake and certain benches) have expansive soils or collapsible soils. If you pour a standard slab-on-grade foundation on this soil, it can crack and settle unevenly.
The Code Requirement
For commercial projects, IBC Section 1803 typically requires a site-specific geotechnical report. Even for residential accessory structures over a certain size (often 3,000 sq. ft.), cities like Salt Lake will mandate a soils report.
The Solution
Budget for a geotechnical investigation early. It is far cheaper to engineer the foundation correctly at the start than to underpin a sinking building five years later.
Build It Right the First Time
Building with steel offers incredible advantages for Utah property owners, but the state’s unique mix of heavy snow, seismic activity, and freezing temperatures demands respect. By accounting for these factors during the planning phase—rather than the construction phase—you can save thousands of dollars and ensure a safe, compliant build.
