Ohio architect seal stamped with pencil on black background, showing Ohio architecture seal and stamp requirements.

The Ohio Architects Board requires each registered architect to submit a unique individual seal with each set of designs, blueprints, or specifications. Just like a fingerprint, this number sets the architect’s work apart and can be tracked even if alterations are needed.

Ohio Architecture Seals and Stamps Design

Per regulations, Ohio architecture seals and stamps must have a circular shape and a 2” diameter. According to the Ohio Architects Board, the outer ring will include “State of Ohio” at the top and “Registered Architect” at the bottom. In the inner circle, will be the licensee’s name and licensure number, placed horizontally.

Landscape architects can expect the same type of Ohio architecture seals and stamps with only a title change on the bottom of the outside ring, and two accents above and below the landscape architect's name and license number. Otherwise, the design remains the same.

Ohio Architecture Seals and Stamps Requirements

Registered architects demonstrate responsible control when using the Ohio architecture seals and stamps. “Responsible control” is the term used to show the architect has provided a standard of care with all materials, instruments, and calculations. The architect has considered environmental and climate changes on a structure as well as human safety.

As of July 1, 2012, the registered architect must now include below the seal, his or her printed name, license number and the expiration date of the license. The date is also required next to the signature.

The front of all blueprints, plans, specifications, and other architectural documents must be sealed and signed, following the above guidelines. Although the Board no longer requires each sheet to be stamped, check with the building department as they may still require the process.

No architect may alter designs bearing Ohio architecture seals and stamps unless he or she has written permission from the original architect. Ohio law also includes written permission from the architect’s estate, if necessary.

If the document is altered, the altering architect must follow Ohio law and seal the document. The document must also be signed, dated, and the architect’s name printed below the seal with the license number and license expiration date. A detailed explanation of the changes must be included. Once a seal has been placed, it must not be removed.

Only individual architects may submit a seal on documents. In the state of Ohio, corporations and firms cannot use seals and will not be issued Ohio architecture seals and stamps.

A registered architect must never allow his or her seal to be used on plans made by a non-professional architect.

No Ohio architecture seals and stamps are required for any residential one-family or two-family building. An architect is not required for most residential additions including garages, carports, decks, porches, and sheds. This exception also includes agricultural buildings, per the Fayette County, Ohio Building Department.

Not always.
