Written by Acorn Sales Company, manufacturing stamps and seals since 1964 · Reviewed by Holly R, VP of Sales and Marketing at Acorn Sales, against the Idaho Board of Architects and Landscape Architects, administered by the Idaho Division of Occupational and Professional Licenses and Idaho Code § 54-3003(9)(b), (9)(b)(i) on 21 September 2026 · Updated 21 September 2026
A written signature and the date go with the seal every single time it is applied. Idaho Code § 54-3003(9)(b)(i) states it as an absolute: “The seal may be a rubber stamp or an electronically applied seal. Whenever the seal is applied, the licensee’s written signature and the date shall be adjacent to or across the seal.” Adjacent is permitted, so signing through the impression is optional, but skipping either the signature or the date is not.
Note the adjective. The statute says written signature for landscape architects, where the Idaho architect statute at § 54-304(2) allows the signature to be applied manually or electronically. One board runs both professions and the two sections do not say the same thing, so an electronically applied seal does not obviously carry an electronically applied signature with it.
The legend is fixed at “Licensed Landscape Architect, State of Idaho,” with the comma and in that order, alongside your name. Everything else comes from the board-approved design: § 54-3003 states no diameter, shape or proportion, and IDAPA 24.01.01 contains no seal rule for either profession. Ask the board for the approved design before you order.

Is a seal required in Idaho?
Idaho carries the landscape architect seal inside one long licensing section. Idaho Code § 54-3003(9)(b) provides that “Every landscape architect shall have a seal approved by the board that contains the name of the landscape architect and the words ‘Licensed Landscape Architect, State of Idaho’,” and subparagraph (i) adds the application rule: “The seal may be a rubber stamp or an electronically applied seal. Whenever the seal is applied, the licensee’s written signature and the date shall be adjacent to or across the seal.”
What must appear on the seal
- Your name
- The words Licensed Landscape Architect, State of Idaho
- Any further content the board has approved
Two statutory elements and a board approval. The legend is exactly “Licensed Landscape Architect, State of Idaho”, with the comma and in that order. The statute does not name the license number as an element, which is different from the Idaho architect seal at § 54-304(1), where the Idaho architect license number is expressly required; the number reaches a landscape architect device, if at all, through the board-approved design. Take the artwork from the board rather than assuming the architect layout carries across, even though one board administers both professions.
Size and shape
Not addressed. Idaho Code § 54-3003 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 for either profession. The sources here are Idaho Code Title 54 ch. 30, §§ 54-3001 through 54-3005, and read IDAPA 24.01.01 for any seal or stamp provision, finding legal authority, scope, licensure, practice standards and fees and no seal section. Because the statute conditions the seal on board approval, ask the board for the approved design before ordering.
Embosser, rubber stamp or digital
Two devices, named in the statute: “The seal may be a rubber stamp or an electronically applied seal.” An embosser is not named. The safe buy is a rubber or self-inking stamp, because the statute requires a written signature and the date adjacent to or across the seal and those have to read together on the document a client or agency receives. Note the contrast within the same board: the Idaho architect statute at § 54-304(2) speaks of applying the seal manually or electronically without naming any device at all.
Signing and dating
A written signature and the date, adjacent to or across the seal, every time. Idaho Code § 54-3003(9)(b)(i) states it as an absolute: whenever the seal is applied, the licensee’s written signature and the date shall be adjacent to or across the seal. Adjacent is permitted, so signing through the impression is optional. Note the adjective: the statute says written signature for landscape architects, where the architect statute at § 54-304(2) allows the signature to be applied manually or electronically. Read the current text before treating an electronic signature as equivalent here.
A written signature and the date, every single time the seal goes down
Idaho Code § 54-3003(9)(b)(i) is short and absolute: whenever the seal is applied, the licensee’s written signature and the date shall be adjacent to or across the seal. There is no document class that escapes it and no draft exception. Note the word written. The Idaho architect statute at § 54-304(2) says the signature may be applied manually or electronically; the landscape architect statute does not repeat that permission, even though one board runs both professions.
Which documents must be sealed
Not addressed as a list. Section 54-3003(9)(b) creates the seal and the signature and date duty and does not enumerate the documents that must carry it; the license requirement and the exemptions sit in the same long section, and IDAPA 24.01.01 adds no sealing rule. The sources here are Idaho Code §§ 54-3001 through 54-3005 and read IDAPA 24.01.01 in full. Seal what you issue: the statute’s phrase “whenever the seal is applied” presupposes application to work product, and Idaho gives no draft or preliminary carve-out for this profession comparable to the one its engineers and land surveyors have at § 54-1215(3)(b).
Electronic and digital seals
Idaho permits an “electronically applied seal” and names no technology, no certificate authority and no verification standard. There is no board approval process for a digital signing method and no stripping language for uncertified electronic transmissions in ch. 54-30 or IDAPA 24.01.01. Note also that the signature requirement in the same subparagraph is expressed as a written signature, so an electronically applied seal does not obviously carry an electronically applied signature with it. Confirm with the board before relying on a fully electronic Idaho landscape architect document.
Renewal, lapse and retirement
Renewal, endorsement, exemptions and fees all sit inside § 54-3003, with disciplinary proceedings at § 54-3004 and violations at § 54-3005. Not addressed: neither ch. 54-30 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 §§ 54-3001 through 54-3005 and read IDAPA 24.01.01 in full. Contrast Idaho engineers and land surveyors, whose § 54-1215(3) makes sealing after expiration, retirement, suspension or revocation unlawful in terms.
Firm requirements
Licenses go to individuals and partnerships are policed. Idaho Code § 54-3003(8)(a) provides that “All licenses shall be issued to individuals only, but nothing contained in this chapter shall prevent a duly licensed landscape architect from rendering professional services for a corporation, firm, partnership or association,” and § 54-3003(8)(b) requires each partner in a partnership of landscape architects to be licensed to practice landscape architecture or to provide allied professional services as defined in Idaho Code § 30-21-901. There is no certificate of authorization, no firm seal and no firm number on the document.
What to check before you order
Ask the Board of Architects and Landscape Architects for the seal design it approves, because Idaho Code § 54-3003(9)(b) requires a board-approved seal and neither the statute nor IDAPA 24.01.01 states a diameter. The statute fixes your name and the words Licensed Landscape Architect, State of Idaho. A rubber stamp or an electronically applied seal are the two permitted forms, and a stamp is the practical choice. Every time you apply the seal, put your written signature and the date adjacent to it or across it. Do not assume the Idaho architect layout transfers: the architect seal must carry the Idaho architect license number by statute, and the landscape architect statute names only the name and the legend.

Frequently asked questions
Is a seal required for landscape architects in Idaho?
Yes. Idaho Code § 54-3003(9)(b) provides that “Every landscape architect shall have a seal approved by the board that contains the name of the landscape architect and the words ‘Licensed Landscape Architect, State of Idaho’,” and subparagraph (i) adds the application rule.
What has to appear on an Idaho landscape architect seal?
Your name, the words Licensed Landscape Architect, State of Idaho, and any further content the board has approved. The statute does not name the license number as an element, which is different from the Idaho architect seal at § 54-304(1), where the Idaho architect license number is expressly required. The number reaches a landscape architect device, if at all, through the board-approved design.
What size is an Idaho landscape architect seal?
Idaho does not state one. Section 54-3003 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 for either profession. Because the statute conditions the seal on board approval, get the approved design from the board before ordering.
Can I use an embosser in Idaho?
The statute names two devices and an embosser is not one of them: “The seal may be a rubber stamp or an electronically applied seal.” A rubber or self-inking stamp is the practical choice, because a written signature and the date have to sit adjacent to or across the seal and read together on the document a client or agency receives.
Does my signature have to cross the Idaho seal?
No. Section 54-3003(9)(b)(i) allows the written signature and the date to be “adjacent to or across the seal,” so either placement works. What is not optional is having both the signature and the date present whenever the seal goes down.
Is an electronic Idaho landscape architect seal allowed?
The statute permits an “electronically applied seal” and names no technology, no certificate authority and no verification standard. There is no board approval process for a digital signing method and no stripping language for uncertified electronic transmissions in chapter 54-30 or in IDAPA 24.01.01. Because the same subparagraph calls for a written signature, confirm with the board before relying on a fully electronic Idaho landscape architect document.
Which Idaho documents have to be sealed?
The chapter does not publish a list. Section 54-3003(9)(b) creates the seal and the signature and date duty without enumerating document classes, the license requirement and the exemptions sit in the same long section, and IDAPA 24.01.01 adds no sealing rule. The statute’s phrase “whenever the seal is applied” presupposes application to work product, and Idaho gives landscape architects no draft or preliminary carve-out comparable to the one its engineers and land surveyors have at § 54-1215(3)(b).
Why does my Idaho seal look different from an Idaho architect seal?
Because the two statutes say different things even though one board administers both professions. The architect seal must carry the Idaho architect license number by statute; § 54-3003(9)(b) names only your name and the legend. The architect statute allows a manual or electronic signature; the landscape architect statute says written signature. Take the artwork from the board rather than assuming the architect layout carries across.
What happens to an Idaho seal if the license lapses?
Neither chapter 54-30 nor IDAPA 24.01.01 says. Renewal, endorsement, exemptions and fees all sit inside § 54-3003, with disciplinary proceedings at § 54-3004 and violations at § 54-3005, and none of them states what happens to the device, whether the license number changes on reinstatement, or whether the seal must be surrendered or destroyed. Contrast Idaho engineers and land surveyors, whose § 54-1215(3) makes sealing after expiration, retirement, suspension or revocation unlawful in terms.
Does an Idaho landscape architecture firm need a seal?
No. Idaho Code § 54-3003(8)(a) provides that “All licenses shall be issued to individuals only, but nothing contained in this chapter shall prevent a duly licensed landscape architect from rendering professional services for a corporation, firm, partnership or association,” and § 54-3003(8)(b) requires each partner in a partnership of landscape architects to be licensed to practice landscape architecture or to provide allied professional services as defined in Idaho Code § 30-21-901. There is no certificate of authorization, no firm seal and no firm number on the document.
