Can an Out-of-State Engineer Stamp My Drawings?

Short answer: generally no. Engineering licenses are issued by each state, and a license in one state does not carry over to another. The engineer who seals your drawings should be licensed in the state where the project will be built, and in the kind of engineering the work needs.

Why licenses stop at the state line

There is no national engineering license in the United States. Each state has its own licensing board, its own rules and its own list of who may seal drawings. Engineers take national exams, but they are then licensed one state at a time. A Professional Engineer licensed in Ohio has no authority to seal drawings for a house in Texas unless they also hold a Texas license.

An engineer who is not licensed in a state can generally work there only under the direct supervision and seal of an engineer who is. Sealing without a license in that state can bring penalties for the engineer and a rejected permit for you.

How an engineer gets licensed in more than one state

Engineers who work in many states apply for a license in each one. A national record kept by the engineering exam body helps with the paperwork, but each state still decides for itself. That is why a firm that covers many states has engineers licensed in many different states, not one engineer who covers them all.

Some states add a structural license

A few states, such as Illinois, have a separate structural engineer license that is required for some buildings. In those states a general Professional Engineer license may not be enough for structural drawings. Which buildings need it depends on the state’s rules.

What this means for your project

• Drawings from a firm in another state are fine, if the engineer holds the license where your project is. Where the firm is located does not matter. Where the engineer is licensed does.
• Old drawings may not be reusable. Plans sealed in one state for a similar house usually cannot be resubmitted in another. The code, the loads and the license all change.
• The seal shows who is responsible. It carries the engineer’s name, license number and state. Seal formats, including whether a digital seal is accepted, differ from state to state.

How to check an engineer’s license

1. Ask for the engineer’s name, license number and the state they are licensed in.
2. Look the license up on that state’s licensing board website. Most boards publish a free public lookup.
3. Confirm the license is active and covers the kind of engineering your project needs.

How we handle it

We match every project to a professional licensed in your project’s state and in the discipline the work needs. The engineer’s name and license number are shared on request, before you approve the quote, and the same name and number appear on the seal of every sheet they sign. See how we work, or requirements by state to see what your state asks for.
