A PE (Professional Engineer) stamp is the seal and signature of a licensed engineer registered in Utah, confirming they prepared or supervised the drawings and take professional responsibility for the design. Under Utah Code 58-22 (Engineering Practice Act), offering engineering services without a current Utah PE license is unlawful. The structural PE stamp is particularly critical because it confirms the structural system was designed to resist IBC/IRC loads — including SDC D seismic loads — at the specific project location. A contractor who produces structural drawings without a PE stamp for SDC D projects produces drawings that will be rejected at permit review and that may not provide adequate structural resistance to earthquake forces. RainFire Builders coordinates licensed structural engineers registered in Utah for every project requiring PE-stamped structural drawings.
