When Does a Building Department Ask for Structural Engineering?
Simple projects that follow the building code’s prescriptive tables may not need an engineer. As soon as a design goes beyond those tables – a longer span, a heavier load, an unusual foundation, high wind or seismic exposure – most building departments require structural drawings or calculations sealed by a licensed PE.
We review your scope at the quote stage and tell you exactly what engineering your jurisdiction is likely to require, so you only pay for what the permit needs.
You Most Likely Need a Structural Engineer If You Are:
- Removing or moving a load-bearing wall
- Using beams or headers longer than code tables allow
- Adding a second story or a new foundation
- Building an elevated deck, roof deck or retaining wall
- Building in a high wind, snow or seismic area
- Working on a commercial, multifamily or change-of-use project

Your Questions About Structural Stamps, Answered
What is a structural stamp?
A structural stamp is the seal of a licensed Professional Engineer applied to structural drawings or calculations. It certifies the engineer designed or reviewed the structure and takes professional responsibility for it.
Do deck plans need an engineer stamp?
Sometimes. Many jurisdictions accept prescriptive deck guides for simple, low decks. Elevated decks, long spans, hot tubs, cantilevers or non-standard connections usually require engineered and stamped plans.
What is the difference between a stamped letter and stamped drawings?
A stamped letter addresses a specific item – such as a beam replacement or damage assessment – in writing. Stamped drawings show the full structural design graphically. Your building department decides which it will accept; we advise you in the quote.
Do you need to visit the site?
Most structural design for permit can be done remotely from drawings, photos and measurements. Where existing conditions are uncertain, we may ask for specific field verification or recommend an on-site assessment.
Can you stamp metal building or barndominium plans?
Yes – foundation plans and structural drawings for steel buildings, kits, barndominiums and post-frame structures, based on the manufacturer’s reactions where applicable.
How much does a structural engineer stamp cost?
Pricing depends on scope, complexity and whether calculations or full drawings are needed. Send your project through the quote form or live chat and you will have a fixed price in 5-10 minutes.
