PE stamp in Minnesota: certification language, not a mandatory seal

When a Minnesota engineer’s certification is required

The Board of Architecture, Engineering, Land Surveying, Landscape Architecture, Geoscience, and Interior Design licenses Professional Engineers. Minnesota Statutes section 326.12 requires each plan or drawing prepared by a licensed engineer, or under that engineer’s direct supervision, to bear the licensee’s signature, a certification that the signer is licensed, the license number, and the date. The project address controls the license.

The building official may require construction documents to be prepared under those licensing rules. Drafts and preliminary sheets exchanged inside an office are treated differently from documents filed for a permit. If the city has asked for a certification, upload that comment. AllInStamp matches a Minnesota-licensed PE and verifies the license before the set is certified.

The words that have to appear on the sheet

Minnesota Rule 1800.4200 makes the certification and signature mandatory. The Board’s language for a professional engineer is: “I hereby certify that this plan, specification, or report was prepared by me or under my direct supervision and that I am a duly Licensed Professional Engineer under the laws of the state of Minnesota,” followed by the signature, the typed or printed name, the license number, and the date. That certification appears on every sheet of plans and drawings, and on the first page of specifications, reports, and similar documents.

A seal is not required. The Board does not prohibit a seal used in addition to the certification. A stamp, a printed signature, or an electronically created signature has the same effect as a handwritten signature when it accurately depicts the licensee’s actual signature. The certification itself may be electronic. Once the document is certified, that signature stays on it.

Where the State Building Code is enforced

The Minnesota State Building Code is the statewide construction standard, and a city, township, or county enforces it when that unit has adopted it by ordinance. The Department of Labor and Industry still administers plan review for certain public buildings and state-licensed facilities. Minneapolis, St. Paul, and most metro cities have adopted the code and run their own portals. Name the jurisdiction.

DLI’s published base for the building and residential chapters remains the 2020 Minnesota State Building Code, built on the 2018 I-codes with Minnesota amendments. Later chapter updates can be in force before those building chapters change. Electrical permits filed on or after August 17, 2026 follow the 2026 National Electrical Code. Confirm the chapter the building official is enforcing, and cite it on the cover.

Snow load and frost depth

Minnesota plan review commonly flags ground snow load and frost depth that do not match the site. DLI publishes snow-load and frost-depth maps for this reason. A Twin Cities value is not a northern Minnesota value. Put the ground snow load, frost depth, and risk category used in the design on the structural notes, and include the calculations.

A sheet that has a seal image and no certification statement is incomplete under the statute. The statement, the name, the license number, the date, and the signature are the items the Board requires.

How to get a Minnesota set certified

Upload the PDF plan set and calculations, and note the city and whether DLI or the local building official is the reviewer. Include prior comments on a resubmittal. Out-of-state drawings can be reviewed. The certification is applied only by a Minnesota licensee whose professional judgment is in the work and who assumes responsibility for it.

Start a new quote with Minnesota prefilled. Intake typically responds within 24–48 hours. Stamp turnaround then follows page count and whether rush service is selected.

FAQ

Does Minnesota require a PE seal on drawings?

No. The statute requires a signature, a certification that the signer is a licensed professional engineer, the license number, and the date. A seal may be added. It does not replace the certification statement.

Is the Minnesota building code enforced in every city?

The code is the statewide standard. A municipality enforces it when it has adopted the code by ordinance. DLI reviews certain public buildings and state-licensed facilities. Name the city so intake can tell which office files the set.

Can a PE licensed in another state certify Minnesota drawings?

No. The certification states that the signer is a duly licensed professional engineer under Minnesota law. AllInStamp routes Minnesota jobs to Minnesota licensees.
