PE Stamping Guides / Permits & Compliance
When Do Building Plans Need a PE Stamp?
A decision framework for determining whether permit drawings need a licensed engineer's seal and which authority should confirm the requirement.

Key takeaways
- The authority having jurisdiction makes the permit-submission determination.
- State licensing rules, adopted building codes, and local amendments can all affect the answer.
- Confirm the required discipline and sheet scope before ordering a review.
Start with the authority having jurisdiction
The building department, fire marshal, utility, or other authority reviewing the project should be the first source for submission requirements. Ask whether sealed documents are required, which discipline must seal them, and whether digital signatures and seals are accepted.
Do not rely on a requirement from a different city or a previous project. Two nearby jurisdictions can use different code editions, amendments, forms, and electronic-submission procedures.
Common situations that trigger engineering review
Requirements vary, but engineered documents are commonly requested when work affects structural safety, life-safety systems, complex mechanical or electrical systems, foundations, retaining structures, specialized equipment, or code calculations.
- Structural alterations, additions, and load-path changes
- Non-prescriptive structural systems or site-specific foundations
- Commercial electrical, mechanical, plumbing, or fire-protection work
- Solar, battery, generator, EV-charging, and equipment-support systems
- Deferred submittals, shop drawings, and specialty-engineered components
Questions to ask before requesting a stamp
A short written confirmation from the reviewer can prevent the wrong discipline or document set from being ordered. Ask for the adopted code edition, required calculations, accepted file format, and whether each sheet or only designated engineering sheets must be sealed.
Frequently asked questions
Does every residential project need a PE stamp?
No. Some residential work may follow prescriptive code provisions, while other work requires engineered design. The local authority should confirm what applies to the specific project.
Can an architect stamp engineering calculations?
Professional-practice boundaries vary by jurisdiction and scope. Confirm the required professional discipline with the reviewing authority and licensing board.
