Structural Engineering & PE-Stamped Drawings
When a plan checker asks for "engineered drawings" or "a PE stamp", they need structural calculations and plans prepared and sealed by a licensed professional engineer. We provide exactly that, for new structures and for changes to existing ones.
Typical requests include removing a load-bearing wall, sizing a beam or header, framing an addition or second story, designing a deck or retaining wall, and checking wind, snow or seismic loads. We provide the stamp your state requires, in all 50 states.
- 24 hours to 7 days, depending on scope
- 98% first-time approval
- PE stamp in all 50 states
What's in your drawing set
- Structural calculation package
- Foundation and footing plans
- Floor, wall and roof framing plans
- Beam, header and connection details
- Lateral design for wind and seismic where required
- Snow and drift loads for your location
- Retaining wall design
- PE seal and signature valid in your state
Common reasons you need a PE stamp
- Removing or altering a load-bearing wall
- New beams, headers or posts
- Additions and second stories
- Decks with hot tubs, roofs or tall posts
- Retaining walls over the local height limit
- Plan-check comments asking for engineering
How it works
- 01
Send your project details
Address, a sketch or photos, and what you want to build. We confirm your city's requirements before drawing.
- 02
We draw and code-check
Your set is drafted to your jurisdiction's adopted code and checked the way a plan reviewer would check it.
- 03
You submit, we support
You get a permit-ready set, and we respond to any plan-check comments until it's approved.
Drawings delivered in 24 hours to 7 days, depending on scope. City review time after submission depends on your jurisdiction.
Frequently asked questions
Can you stamp drawings in my state?
Yes. We provide PE stamps in all 50 states.
Can you just stamp drawings I already have?
Yes. We review your existing drawings for structural adequacy and code compliance, make any needed corrections, and then seal them. See our stamp and seal review service.
Do I need an engineer to remove a wall?
If the wall is load-bearing, almost always. The beam, posts and footings that replace it have to be designed and documented.
How fast can I get structural calcs?
Simple beam or header calcs are often ready in 24–48 hours. Full framing and foundation packages are delivered within 7 days.
Already have drawings that just need a seal? See our PE stamp & seal review.
