The Washington rules in full, with citations

WAC 196-23-070 is "Signature", not the seal rule; the seal is WAC 196-23-010 and its usage is WAC 196-23-020. WSR 25-02-004, filed December 18, 2024 and effective January 18, 2025, amended WAC 196-23-010, but it was an expedited, non-substantive rule making that changed pronouns only. The illustrated designs are printed in the certified PDF of the section, not in the HTML version. RCW 18.96.150 is titled “Certificates of licensure—Issuance—Contents—Seal” and its subsection (1) concerns the certificate of licensure signed by the chair of the board and the director; the licensee’s own seal is subsection (2). WAC 308-13-055 is written throughout in the second person — subsection (2) reads “You must seal/stamp the following” — and the sentence applying the sealing requirements “without exception … to all work prepared or supervised by the landscape architect” is a separate unnumbered paragraph that follows subsection (3), not part of (3) itself.

Landscape Architect seal

Rule:: WAC 308-13-055; RCW 18.96.150(2)
Diameter:: No diameter is prescribed. WAC 308-13-055 says only that "the size of the seal/stamp may be adjusted provided it remains readable. Other deviations are not allowed," and RCW 18.96.150(2) states no dimension.
Legend:: “Licensed landscape architect, state of Washington”

"If you were issued your initial license on or after January 1, 2017, you must have a seal/stamp of the design authorized by the board, bearing your name, license number and the legend 'Licensed landscape architect, state of Washington.' The size of the seal/stamp may be adjusted provided it remains readable. Other deviations are not allowed." (WAC 308-13-055)
"If you were licensed before January 1, 2017, you may continue to use your existing registration stamp." (WAC 308-13-055)
"Your seal/stamp must include your signature and your license expiration date." (WAC 308-13-055(1))
You must seal/stamp "(a) All technical submissions required for building permits, regulatory approvals and/or construction drawings that are filed with authorities having jurisdiction; (b) Drawings prepared by you on each sheet; (c) Specifications and other technical submissions need only be sealed/stamped on the cover, title page, and all pages of the table of contents." (WAC 308-13-055(2))
“Your seal/stamp shall not be affixed to any drawings not prepared by you or your regularly employed subordinates, or not reviewed by you. If you seal/stamp drawings or specifications that you have reviewed, you shall be responsible to the same extent as if those drawings or specifications were prepared by you.” (WAC 308-13-055(3))
“Without exception, these sealing/stamping requirements for landscape architects shall apply to all work prepared or supervised by the landscape architect.” (WAC 308-13-055 (unnumbered paragraph following subsection (3)))
A signature may be "[a] handwritten identification or a digital representation of your handwritten identification that represents the act of putting your name on a document to attest to its validity," which must be "[o]riginal and written by hand, or a scanned image of an original, handwritten identification," "[p]ermanently affixed to the document(s) being certified," "[a]pplied to the document by the identified licensee," and "[p]laced adjacent to the seal/stamp of the licensee." (WAC 308-13-055(4)(a))
A digital identification is permitted: it "is an electronic authentication process attached to or logically associated with an electronic document," and must be "[u]nique to the licensee using it," "[c]apable of independent verification," "[u]nder the exclusive control of the licensee using it," and "[l]inked to a document in such a manner that the digital identification is invalidated if any data in the document is changed." (WAC 308-13-055(4)(b))
"Each licensee shall obtain a seal of the design authorized by the board bearing the landscape architect's name, license number, the legend 'Licensed Landscape Architect,' and the name of this state. Drawings prepared by the licensee shall be sealed and signed by the licensee when filed with public authorities." (RCW 18.96.150(2))
"It is unlawful to seal and sign a document after a licensee's certificate of licensure or authorization has expired, been revoked, or is suspended." (RCW 18.96.150(2))

FAQ

Washington Landscape Architect Seal FAQs

Frequently asked questions about Washington digital landscape architect stamps and seals.

How do I obtain a digital Washington landscape architect seal or stamp?

Once you are licensed in Washington, you can generate your seal here and download it immediately. Fill in the form and position your signature if you want one. The layout follows WAC 308-13-055; RCW 18.96.150(2), which is the provision the Board of Licensure for Landscape Architects (Washington State Department of Licensing) will measure the seal against.

What are the requirements for the Washington landscape architect stamp or seal?

Washington’s landscape architect seal rule is WAC 308-13-055; RCW 18.96.150(2), administered by the Board of Licensure for Landscape Architects (Washington State Department of Licensing), a different body from the engineering board. The seal must carry “Licensed landscape architect, state of Washington”, and no diameter is prescribed. WAC 308-13-055 says only that "the size of the seal/stamp may be adjusted provided it remains readable. Other deviations are not allowed," and RCW 18.96.150(2) states no dimension.

A further 10 requirements, each tied to the subsection that imposes it, are itemised in the Washington requirements section on this page.

What size does a Washington landscape architect seal have to be?

WAC 308-13-055; RCW 18.96.150(2) governs the Washington landscape architect’s seal but does not prescribe a diameter. Sizes quoted for Washington elsewhere generally come from stamp suppliers’ catalogues rather than from the rule. What the rule does require is that your name and license number stay clearly legible.

Which date goes on a Washington landscape architect seal?

The date on a Washington stamp is the license expiration date, not the date you signed — the board design carries "EXP." on its face. Is your stamp showing a signing date where the expiration date belongs? (WAC 308-13-055(1))

Can you modify the board's seal artwork?

Size is the only thing the rule lets you change. WAC 308-13-055 permits the seal to be resized so long as it stays readable but states "Other deviations are not allowed" — redrawing the tree graphic or altering the legend is a deviation. (WAC 308-13-055)

Does every page of a specification book need a stamp?

Specifications and other technical submissions "need only be sealed/stamped on the cover, title page, and all pages of the table of contents," whereas drawings must be sealed on each sheet. (WAC 308-13-055(2)(b), (c))

Does a pre-2017 Washington stamp have to be replaced?

Licensees issued their initial license before January 1, 2017 "may continue to use" the existing registration stamp, so an older Washington seal is not automatically non-compliant. (WAC 308-13-055)
