Pole Barn, Garage and Shed Engineering
Stamped plans for detached garages, pole barns and large sheds, including post embedment, trusses and snow and wind loads.
What the work involves
Detached garages and post-frame buildings often need stamped plans because they fall outside prescriptive residential tables or exceed size limits for exempt accessory structures. The engineer designs post embedment or footings, trusses or framing, bracing and connections for local snow, wind and seismic loads. Kit building suppliers sometimes provide generic stamped drawings, but local departments may require site-specific engineering.
Local conditions we plan for
- Expansive clay soils
- Tornadoes and severe storms
- Induced seismicity linked to wastewater injection
- Flash flooding
Building code: 2018 IBC/IRC adopted at the state level (ICC adoption chart, April 2026). Rules adopting newer editions were pending with a September 14, 2026 effective date.
When you need it
- Accessory building larger than the local permit-exempt size (often 120 to 200 sq ft)
- Post-frame (pole barn) construction
- High snow or wind load area
- Living space, loft or heavy storage above
