An unsealed Idaho permit submission is deemed unacceptable, not merely deficient. Idaho Code § 54-304(3) provides that technical submissions presented to a governmental agency for a building permit that do not carry the architect’s affixed seal, signature and date are deemed unacceptable. That puts the date on the same footing as the seal.
The face carries four things, all statutory: your name, your Idaho architect license number, the words licensed architect and the words state of Idaho. Idaho says licensed rather than registered, and it treats state of Idaho as a separate element from the number. Do not carry over the Idaho landscape architect legend; the two professions sit under one board but under different chapters of the Idaho Code.
There is no Idaho architect seal diameter to find. Idaho Code § 54-304 prescribes no diameter, shape or proportion, and IDAPA 24.01.01, the Rules of the Board of Architects and Landscape Architects, contains no seal rule at all. Sections 54-301 through 54-316 and the whole of IDAPA 24.01.01 read the same way, and the Division publishes no dimensioned artwork. Size the device for legibility on a technical submission, and treat any quoted Idaho standard diameter as a trade convention.

Is a seal required in Idaho?
Idaho puts the entire architect seal rule in statute. Idaho Code § 54-304(1) provides that “Every licensed architect shall have a seal, the impression of which must contain the name and Idaho architect license number of the architect and the words ‘licensed architect’ and ‘state of Idaho,’ with which he shall seal all technical submissions issued from his office.” Subsection (2) requires the signature, date and seal to appear on all technical submissions prepared by the architect or meeting the requirements of subsection (4). Subsection (3) supplies the sanction: technical submissions presented to a governmental agency for a building permit that do not carry the architect’s affixed seal, signature and date are deemed unacceptable.
What must appear on the seal
- Your name
- Your Idaho architect license number
- The words licensed architect
- The words state of Idaho
Four elements, all statutory, and the statute does not delegate the design to the board the way Idaho does for landscape architects at § 54-3003(9)(b) or for engineers and land surveyors at § 54-1215(3)(e). Note the exact wording: Idaho says licensed architect, not registered architect, and it says state of Idaho as a separate element from the license number. Nothing about a firm, a discipline or an expiry date is authorized. Do not carry over the Idaho landscape architect legend “Licensed Landscape Architect, State of Idaho”; the two professions sit under one board but under different chapters of the Idaho Code.
Size and shape
Not addressed. Idaho Code § 54-304 prescribes no diameter, shape or proportion, and IDAPA 24.01.01, the Rules of the Board of Architects and Landscape Architects, contains no seal rule at all. The sources here are §§ 54-301 through 54-316 in the Idaho Code and read IDAPA 24.01.01 for any seal or stamp provision, and found the chapter to cover legal authority, scope, licensure, practice standards and fees with no seal section. The Division of Occupational and Professional Licenses publishes no dimensioned artwork on the Board’s statutes, rules and guidance page. Size the device for legibility on a technical submission.
Embosser, rubber stamp or digital
The statute regulates application, not the device. Idaho Code § 54-304(2) provides that the seal, signature and date “may be applied manually or electronically,” and names no physical format: the words embossed, crimp and rubber stamp do not appear in § 54-304. That is a real difference from Idaho engineers and land surveyors, whose § 54-1215(3)(a) expressly lists a rubber stamp, a crimp or an electronically generated image. A rubber or self-inking stamp is the safe buy, because subsection (3) makes a permit submission unacceptable unless the seal, signature and date are affixed and visible.
Signing and dating
Signature, date and seal travel together: “The signature, date and seal shall appear on all technical submissions prepared by the architect or that meet the requirements set forth in subsection (4).” All three may be applied manually or electronically. Idaho then provides a route for informational electronic copies: they may display only the seal if they note that the original is filed elsewhere, identify the storage location, and include the words indicating that the original was signed and giving the date the original was signed, adjacent to or across the seal. The statute does not require the signature to cross the impression.
Idaho puts the architect seal in statute and the board rule says nothing
Most states split the job: the statute creates the seal and the board rule prescribes the artwork. Idaho does not. Idaho Code § 54-304 carries the elements, the application rule, the permit sanction, the who-may-seal test and the five year record duty, and IDAPA 24.01.01, the Rules of the Board of Architects and Landscape Architects, contains no seal rule at all. There is therefore no Idaho architect seal diameter to find, and a vendor who quotes one is quoting something else.
Which documents must be sealed
All technical submissions issued from the architect’s office, and specifically all technical submissions the architect prepared or that qualify under subsection (4). Subsection (4) sets out what an architect may sign and seal: submissions the architect prepared, work prepared under the architect’s supervision, work by another Idaho licensed architect that the signing architect has reviewed and coordinated, and prototypical documents by a nationally certified architect that the signing architect has integrated into his or her own submissions. Subsection (5) permits an architect to seal work not required by law to be sealed where the architect has reviewed it and integrated it into his or her own submissions. Subsection (6) requires records demonstrating control and knowledge, or review and integration, to be kept for five years. The commercial consequence is in subsection (3): an unsealed, unsigned or undated submission to a governmental agency for a building permit is deemed unacceptable.
Electronic and digital seals
Idaho names no technology and creates no approval process. The statute simply allows the seal, signature and date to be applied manually or electronically, and then regulates the informational copy: an electronic copy issued for information may display the seal alone provided it notes that the original is filed elsewhere, identifies where the original is stored, and carries the original-signed wording and the date the original was signed near the seal. No certificate authority, cryptographic standard or verification service is named, and IDAPA 24.01.01 adds nothing.
Renewal, lapse and retirement
Renewal and reinstatement sit at Idaho Code § 54-312 and discipline at § 54-314, with a misdemeanour provision at § 54-315. Not addressed: neither § 54-304 nor IDAPA 24.01.01 says what happens to the seal on expiration, suspension or revocation, whether the license number changes on reinstatement, or whether the device must be surrendered or destroyed. The sources here are §§ 54-301 through 54-316 and read IDAPA 24.01.01 for any seal provision. Contrast Idaho engineers and land surveyors, whose § 54-1215(3) makes it unlawful to affix a seal after a license has expired or has been retired, suspended or revoked.
Firm requirements
Not applicable. Idaho Code ch. 54-3 contains no certificate of authorization provision for architecture firms: the chapter runs from short title and legislative intent through definitions, the architect’s seal, license required, exemptions, board organization and powers, qualifications, endorsement, temporary license, renewal, fees, discipline, the misdemeanour section and severability, with no business entity registration among them. The architect’s individual seal carries the document. That is a difference from Idaho engineers and land surveyors, who face a certificate of authorization at Idaho Code § 54-1235 with a Secretary of State name filter attached.
What to check before you order
Order a device carrying four things: your name, your Idaho architect license number, the words licensed architect and the words state of Idaho. Idaho states no diameter anywhere, in the statute or in the board rules, so size for legibility on a drawing sheet. Buy a stamp rather than an embosser: the statute makes a permit submission unacceptable if the seal, signature and date are not affixed, and an impression that will not reproduce is a risk. Put your signature and the date with the seal on every technical submission issued from your office; both may be applied manually or electronically. If you issue an electronic copy for information only, show the seal, note that the original is filed elsewhere, say where it is stored, and carry the original-signed wording with the date the original was signed next to the seal. Keep your supervision and integration records for five years.

Frequently asked questions
Is an architect seal required in Idaho?
Yes. Idaho Code § 54-304(1) provides that “Every licensed architect shall have a seal, the impression of which must contain the name and Idaho architect license number of the architect and the words ‘licensed architect’ and ‘state of Idaho,’ with which he shall seal all technical submissions issued from his office.” Subsection (2) requires the signature, date and seal on all technical submissions the architect prepared or that meet the requirements of subsection (4).
What has to appear on an Idaho architect seal?
Four elements from § 54-304(1): your name, your Idaho architect license number, the words licensed architect, and the words state of Idaho. The statute does not delegate the design to the board, which it does do for landscape architects at § 54-3003(9)(b) and for engineers and land surveyors at § 54-1215(3)(e). Nothing about a firm, a discipline or an expiry date is authorized.
What size is an Idaho architect seal?
No size is prescribed anywhere. Section 54-304 states no diameter, shape or proportion, and IDAPA 24.01.01 has no seal rule: the chapter covers legal authority, scope, licensure, practice standards and fees. Sections 54-301 through 54-316 add nothing. Size for legibility on a drawing sheet.
Can I use an embosser in Idaho?
The statute regulates application rather than the device. Section 54-304(2) provides that the seal, signature and date “may be applied manually or electronically,” and names no physical format: the words embossed, crimp and rubber stamp do not appear in § 54-304 at all. That is a real difference from Idaho engineers and land surveyors, whose § 54-1215(3)(a) expressly lists a rubber stamp, a crimp or an electronically generated image. A rubber or self-inking stamp is the safe buy, because subsection (3) makes a permit submission unacceptable unless the seal, signature and date are affixed and visible.
Do the signature and date have to cross an Idaho seal?
No. Section 54-304(2) requires that “The signature, date and seal shall appear on all technical submissions prepared by the architect or that meet the requirements set forth in subsection (4),” and all three may be applied manually or electronically. The statute does not require the signature to cross the impression.
Whose work can an Idaho architect seal?
Four categories under § 54-304(4): submissions you prepared, work prepared under your supervision, work by another Idaho licensed architect that you have reviewed and coordinated, and prototypical documents by a nationally certified architect that you have integrated into your own submissions. Subsection (5) permits sealing work not required by law to be sealed where you have reviewed it and integrated it into your own submissions. Subsection (6) requires records demonstrating control and knowledge, or review and integration, to be kept for five years.
Can I send a client a sealed PDF in Idaho?
There is a route for it, and it has conditions. An electronic copy issued for information may display only the seal provided it notes that the original is filed elsewhere, identifies the storage location, and includes the words indicating that the original was signed together with the date the original was signed, adjacent to or across the seal. Sending a sealed file without that apparatus is not what § 54-304(2) contemplates.
Does Idaho name an electronic signature standard?
No technology is named and no approval process exists. The statute allows the seal, signature and date to be applied manually or electronically, and then regulates the informational copy. No certificate authority, cryptographic standard or verification service appears anywhere, and IDAPA 24.01.01 adds nothing.
What happens to my Idaho seal if my license lapses?
Renewal and reinstatement sit at Idaho Code § 54-312 and discipline at § 54-314, with a misdemeanour provision at § 54-315. Neither § 54-304 nor IDAPA 24.01.01 says what happens to the seal on expiration, suspension or revocation, whether the license number changes on reinstatement, or whether the device must be surrendered or destroyed. Sections 54-301 through 54-316 and the whole of IDAPA 24.01.01 read the same way. Idaho engineers and land surveyors are treated differently: § 54-1215(3) makes it unlawful to affix a seal after a license has expired or has been retired, suspended or revoked.
Does an Idaho architecture firm need registration?
No. Idaho Code ch. 54-3 contains no certificate of authorization provision for architecture firms. The chapter runs from short title and legislative intent through definitions, the architect’s seal, license required, exemptions, board organization and powers, qualifications, endorsement, temporary license, renewal, fees, discipline, the misdemeanour section and severability, with no business entity registration among them. The individual seal carries the document. Idaho engineers and land surveyors do face a certificate of authorization at § 54-1235.
