Brigham City, Tremonton, Perry, Willard, Corinne and Garland: Box Elder sits at the north end of the Wasatch Front. Heavy ag and hay-storage demand, and a snow load closer to Cache Valley's than Salt Lake's.
| Code criteria (Box Elder County) | Value | What it means for your build |
|---|---|---|
| Building-permit threshold | 200 sq ft (IRC default) | Under 200 sq ft is usually permit-exempt but still needs zoning compliance & setbacks. |
| Ground snow load | ≈42 psf (Brigham City, ~4,423 ft) | Heavier than Davis or Salt Lake County, closer to Cache Valley's load. Mantua & Sardine Canyon areas run higher. |
| Design wind speed | ~90–105 mph typical | Standard Wasatch-area wind; not flagged as a special wind region. |
| Seismic design category | D / D1 (confirm per site) | Northernmost mapped trace of the Wasatch Fault passes near Brigham City. Engineered anchorage required. |
| Frost / footing depth | 30″ (more at elevation) | Foundation must bear below frost line. |
| Adopted codes | 2021 I-codes · 2020 NEC | Statewide since July 1, 2023. |
Figures shown are representative Brigham City values. Box Elder County is a Utah Snow Load Study "case study" area. Your engineer determines the exact site value. Verify permit specifics with your city building department.
Box Elder County cities generally follow the Utah default: a detached accessory building over 200 sq ft needs a building permit. Under 200 sq ft is typically permit-exempt but still has to meet your city's setback and zoning rules. A metal garage or shop with a foundation and electrical needs a permit regardless of size.
Box Elder is Utah's northern ag corridor. Hay sheds, equipment storage, and open-front farm buildings are common requests. Cold-formed steel handles wide clear spans well for this kind of use, and every building still ships with PE-stamped engineering sized to your site.
Brigham City's valley-floor design ground snow load runs around 42 psf at roughly 4,423 ft elevation. Meaningfully heavier than Davis County (30 psf) or Salt Lake County (28 psf), and closer to Cache Valley's 43 psf. If your property sits toward Mantua or up Sardine Canyon, expect the engineered value to run higher still.
Over 200 sq ft requires a building permit in most Box Elder cities. Confirm your specific city's setback and zoning rules before you build.
