A PE stamp (Professional Engineer stamp) is a seal applied by a licensed Professional Engineer that certifies engineering drawings meet applicable codes and standards. Most municipalities require PE-stamped drawings for permit applications.
Most PE stamp projects on PPF are completed within 2–5 business days. Rush turnaround (24–48 hours) is available from many engineers for an additional fee.
PE stamp packages start around $300–$600 for simple residential projects (solar, structural elements). More complex commercial projects run $800–$2,500.
PPF has licensed PEs in all 50 states. When you post your project, you'll be matched with engineers licensed in your specific state.
