Written by Acorn Sales Company, manufacturing stamps and seals since 1964 · Reviewed by Holly R, VP of Sales and Marketing at Acorn Sales, against no Michigan board; the profession is unregulated in this state and Mich. Comp. Laws, Occupational Code, 1980 Act 299, arts. 1 to 29 (no interior design article) on 21 September 2026 · Updated 21 September 2026
Michigan does not license, register or certify interior designers, so nothing about your stamp is prescribed. The Occupational Code, 1980 Act 299, has an article for architects, professional engineers and professional surveyors at Article 20 and a separate article for landscape architects at Article 22. It has none for interior designers, and interior design does not appear on the list of occupational professions the Department of Licensing and Regulatory Affairs publishes for its Licensing Division. There is no board issuing numbers, no rule fixing a legend and no Michigan building official looking for an interior designer seal on a submission.
That leaves the device entirely to you. No diameter, no wording, no artwork to match. Any stamp a Michigan interior designer carries is a business stamp rather than a professional seal, which means Acorn will make it to whatever you want on it: your own name, your firm name, a monogram, your logo, or a credential you actually hold such as NCIDQ.
Michigan does police two neighboring titles, and that is the line to stay behind. MCL 339.2014 and MCL 339.2211 restrict the use of the architect and landscape architect titles and descriptions. Put your own name, your firm name, and any credential you actually hold, such as NCIDQ. Leave off “Licensed” and “Registered” and any state-issued title unless the state issued you one, because that is the part some states do restrict.

Is a seal required in Michigan?
Michigan does not license, register or certify interior designers, and therefore issues no interior designer seal. The Department of Licensing and Regulatory Affairs publishes the list of occupational professions its Licensing Division regulates with the state licensing boards, and interior design is not among them. The Occupational Code, 1980 Act 299, has no article for interior designers: Article 20 covers architects, professional engineers and professional surveyors, and Article 22 covers landscape architects. There is no Michigan administrative rule set for interior design, no license number to inscribe and no legend to letter.
What must appear on the seal
- Michigan licenses no interior designers and issues no interior design seal
There is nothing to specify. Because Michigan grants no interior design credential, no wording is authorized and no wording is prohibited by a licensing board. What is policed is the neighboring title: MCL 339.2014 and MCL 339.2211 restrict the use of architect and landscape architect titles and descriptions, so an interior designer practicing in Michigan must not letter a device or a title block in a way that implies architectural or landscape architectural licensure.
Size and shape
No dimension exists. Michigan prescribes no interior designer seal, so there is no diameter to state. The sources here are the Occupational Code article list for 1980 Act 299 and the Department of Licensing and Regulatory Affairs Occupational Professions list, which names the professions the Licensing Division regulates.
Embosser, rubber stamp or digital
Not a regulated purchase. Any device a Michigan interior designer uses is a business stamp, not a professional seal, and it carries no statutory effect. A Michigan building department cannot accept an interior designer stamp in place of the seal of an architect or professional engineer, because MCL 339.2008(1) requires the seal of the licensee in responsible charge on documents submitted to a governmental agency for approval or record.
Signing and dating
Not addressed, because no Michigan credential exists to attach a signature duty to. Where a Michigan project requires sealed documents for a governmental agency, the signature and seal obligation falls on the licensed architect, professional engineer or professional surveyor in responsible charge under MCL 339.2007(2).
There is no Michigan interior designer stamp to buy, and that is the answer
Michigan regulates fourteen occupational professions through its Licensing Division, and interior design is not one of them. The Occupational Code has an article for architects, professional engineers and professional surveyors, and a separate article for landscape architects. It has none for interior designers. No board issues a number, no rule sets a legend, and no Michigan building official is looking for an interior designer seal on a submission.
Which documents must be sealed
No interior design document requires an interior designer seal in Michigan. The sealing duty attaches to the plan, plat, drawing, map, title sheet of specifications, addendum, bulletin, report and bound index sheets listed at MCL 339.2008(1), and it is discharged by the licensed architect, professional engineer or professional surveyor in responsible charge.
Electronic and digital seals
Not applicable. The electronic seal and electronic signature definitions at MCL 339.2007(3) attach to Article 20 licensees. Michigan has no interior design credential and therefore no electronic interior design seal standard.
Renewal, lapse and retirement
Not applicable. With no credential there is no renewal cycle, no lapse, no number to change and no device to surrender.
Firm requirements
Not applicable. Michigan registers no interior design firm and issues no certificate of authorization for interior design. The firm provision at MCL 339.2010 reaches only architecture, professional engineering and professional surveying.
What to check before you order
You do not need, and cannot lawfully obtain, a Michigan interior designer seal, because Michigan does not license or register the profession. If you want a device for your own drawings, order a plain business or identification stamp with your name and firm. Keep the words architect and landscape architect off it, because MCL 339.2014 and MCL 339.2211 restrict those titles in Michigan. If your work is going to a Michigan building department for approval or record, the sealed document has to carry the seal of the licensed architect or professional engineer in responsible charge under MCL 339.2008(1), and no interior design device substitutes for it.

Frequently asked questions
Does Michigan license interior designers?
No. The Occupational Code, 1980 Act 299, runs from Article 1 to Article 29 and contains no interior design article, and the Department of Licensing and Regulatory Affairs list of occupational professions its Licensing Division regulates does not include interior design. There is no Michigan administrative rule set for the profession, no license number to inscribe and no legend to letter.
Can I use a stamp on my Michigan interior design drawings?
Yes, as identification. It is a business stamp with no statutory effect, which is a different thing from a professional seal but a perfectly useful object: it puts your name, your firm and your contact details on a sheet in one action. Nothing in Michigan law prescribes or prohibits its size, shape or wording.
What should I keep off a Michigan interior designer stamp?
The words architect and landscape architect, and anything close to them. MCL 339.2014 and MCL 339.2211 restrict those titles and descriptions in Michigan, and a stamp that drifts toward them on a Michigan drawing invites a complaint even though the interior design work itself is unregulated. Naming the NCIDQ certificate from the Council for Interior Design Qualification in plain words is accurate and carries no such risk.
What size should a Michigan interior designer stamp be?
Whatever reads well on your sheets. Michigan prescribes no interior designer seal, so there is no diameter to match. Neither the Occupational Code article list for 1980 Act 299 nor the Department of Licensing and Regulatory Affairs list of regulated occupational professions offers a figure, because neither creates the credential.
Will a Michigan building department accept my stamp?
Not in place of a licensee’s seal. MCL 339.2008(1) requires the seal of the licensee in responsible charge on documents submitted to a governmental agency for approval or record, and lists the plan, plat, drawing, map, title sheet of specifications, addendum, bulletin, report and bound index sheets that carry it. That duty is discharged by the licensed architect, professional engineer or professional surveyor in responsible charge, under MCL 339.2007(2).
Does my out-of-state interior design credential work in Michigan?
It describes a credential another state issues, and Michigan neither issues nor recognizes one on a filed document. A Certified Interior Designer stamp from Maryland, a Registered Interior Designer stamp from Georgia or North Carolina and a Certified Interior Designer stamp from California all describe real credentials in their own states and none of them in Michigan. If you want an out-of-state registration visible, name the issuing state expressly.
Can I sign Michigan interior design documents electronically?
Nothing restricts you. The electronic seal and electronic signature definitions at MCL 339.2007(3) attach to Article 20 licensees. Michigan has no interior design credential and therefore no electronic interior design seal standard, so how you apply a signature or a stamp image to a PDF is an office decision.
Does a Michigan interior design firm need a certificate of authorization?
No. Michigan registers no interior design firm and issues no certificate of authorization for interior design, because the firm provision at MCL 339.2010 reaches only architecture, professional engineering and professional surveying.
Is there a Michigan interior design renewal to track?
None. With no credential there is no renewal cycle, no lapse, no number to change and no device to surrender. A private certification such as NCIDQ renews on the issuing organization’s own schedule and has no bearing on Michigan practice authority.
Who signs and seals a Michigan interior project that needs a permit?
The licensed architect, professional engineer or professional surveyor in responsible charge, under MCL 339.2007(2) and MCL 339.2008(1). Your drawings can form part of that submission. No interior design device, from Michigan or anywhere else, substitutes for the licensee’s seal.
