Can an Engineer Stamp Another Architect's Drawings?

What a stamp actually means

A professional engineer's seal is a personal certification, not a formality. By sealing a sheet, the engineer states that the work shown was prepared under the engineer's responsible charge or was reviewed thoroughly enough that the engineer accepts it as the engineer's own work. That statement carries legal weight. If the design fails, the sealing engineer answers for it: to the building department, to the licensing board, and in court if people get hurt or property gets damaged. This is why the review cannot be skipped or rushed into a same-day favor. The engineer is not selling ink. The engineer is putting a license, a livelihood, and years of professional standing behind your drawings. Understand that, and the rest of the process makes sense. The fee pays for the checking, the judgment, and the risk the engineer absorbs when the seal goes on. A cheap, instant stamp is cheap precisely because none of that work happened, and the risk lands back on you when the building department or an inspector starts asking questions.

Responsible charge, stated plainly

Most states use a responsible-charge standard, and it is the rule that governs this entire topic. In plain terms, the engineer must have genuine oversight of the work or must review it to the same depth as if the engineer had produced it. Reviewing to that depth means understanding the design intent, verifying the load paths, checking the governing calculations, and confirming the details actually work as drawn. It does not mean flipping through the set, confirming the title block looks professional, and sealing the cover sheet. Some states also have rules about how work prepared by others may be adopted, sealed, and documented, and those rules vary. A legitimate engineer follows the rules of the state where your project will be built, because that state's board licenses the engineer for that project and enforces its standards. If an engineer cannot explain the responsible-charge requirement for your state in plain language, that is a red flag. Torch states it up front on every review engagement so you know exactly what you are buying before any work starts.

What a legitimate review involves

A legitimate review starts with the full set, read sheet by sheet. The engineer checks the calculations behind the design: loads, sizes, connections, and the code provisions the designer relied on. Where calculations are missing, the engineer runs the numbers independently or requires the designer to provide them. The engineer verifies details, meaning the connections and conditions that drawings often leave vague, because buildings fail at connections far more often than in the middle of a beam. The engineer also confirms the drawings are complete and buildable: dimensions agree across sheets, schedules match the plans, and nothing essential is left to be figured out in the field. Anything deficient gets marked up and sent back for revision before sealing. Expect markup. Markup is evidence the review actually happened. Once revisions come back, the engineer spot-checks the corrected areas and confirms nothing else shifted. Only then does the seal go on. That sequence, review, markup, revision, verification, seal, is the legitimate path, and there is no honest shortcut around it.

What a bare stamp is, and why Torch does not sell one

A bare stamp is a seal applied to drawings the engineer has not reviewed, sold as a shortcut past plan check. It goes by softer names in the market, but the arrangement is the same: pay a fee, get a seal, skip the engineering. Torch does not sell one, and you should not buy one from anyone. The reasons are practical, not just ethical. First, it violates the licensing rules in every state, and boards discipline engineers for it, which can void the very approval you paid for. Second, an unreviewed design keeps all its errors. Plan check may miss some of them. The field will not. You will pay for those errors in change orders, failed inspections, tear-outs, or worse. Third, when something goes wrong, the paperwork shows you bought a seal on a design nobody verified, and that fact follows the owner and the builder, not just the engineer. Review-and-seal done properly protects you. It gives you a second, licensed set of eyes on a design you are about to spend real money building. That protection is the product. Anything less is a liability wearing a stamp.

What the engineer needs from you

Provide the full drawing set, any calculations behind it, and product or equipment cut sheets where relevant. Bring the geotechnical report if the project has one, plus any prior plan check comments, because correction lists tell the reviewing engineer exactly where the jurisdiction already has concerns. The cleaner and more complete the package, the faster and cheaper the review. Gaps cost time. If calculations do not exist, the engineer has to create them to verify the design, and that is additional scope you should hear about early, in writing, before the work starts. Be ready to get the original designer involved. Questions about design intent come up in almost every review, and the designer answers them in minutes while a reviewer may need hours to reconstruct the reasoning. Drawings with unresolved code issues or details the engineer cannot verify will come back with required changes, or be declined. A declined review is not a failure of the process. It is the process working, and it is far cheaper to learn a design cannot be sealed at your desk than at the permit counter or on site.

Limits, competence, and who seals what

An engineer generally stamps only the portions within their competence and license. A structural engineer stamps structure, not the electrical design. A civil engineer seals grading, drainage, and site work. Mechanical and electrical designs belong to engineers licensed and competent in those disciplines. On a typical architect-led set, that means you may need more than one engineer involved, each sealing their own discipline's sheets. Any engineer offering to seal every discipline on the set, sight unseen, is telling you the review is not real. There are also project types where review-and-seal is the wrong tool entirely. If the design is early, incomplete, or fundamentally noncompliant, the efficient path is engaging an engineer of record to finish or redo the engineering properly, with the designer coordinating directly. Torch will tell you which situation you are in after a first look at the set. You get a straight answer, a defined scope for the review, and permit-ready drawings at the end of it, because the set is not finished when it is drawn, it is finished when it clears.

How the engagement runs, step by step

Here is how a review-and-seal engagement runs in practice. You send the complete package. The engineer does an intake review to confirm the set is reviewable and to scope the work, then quotes the review as defined scope so you know the cost before committing. The detailed review follows, with markup returned to you and the designer in one consolidated pass wherever possible, rather than dribbled out comment by comment. The designer revises, the engineer verifies the revisions, and the engineer seals the sheets within the engineer's discipline and license. If plan check issues corrections afterward, the engineer supports the response for the sealed work, working the comments with you until they close. Timelines depend on the size of the set and the quality of what arrives. A clean, complete, well-calculated set moves quickly. A set with missing calculations or unresolved code issues takes longer, because the review has to do the work the original package skipped. Either way, you end with a seal that means something: a licensed engineer reviewed your drawings, required what needed fixing, and stands behind the result.

The bottom line

Yes, with a proper review first — that is both the legal requirement and what protects you. Bring a complete set, expect markup, and avoid anyone who will seal it without reading it.
