Wisconsin Landscape Architect seal requirements: proper sizing, signing and sealing of documents
As of
Wisconsin's seal rule for landscape architects is the general registration-seal rule at Wis. Admin. Code § A-E 2.02, not the landscape architect chapter (A-E 9 contains no seal provision). The seal must be between 1-5/8 and 2 inches in overall diameter and must include the credential holder's name, credential number and city; the design approved in A-E 2.02(2) carries "WISCONSIN" and "LANDSCAPE ARCHITECT" around the ring. Each sheet must be signed, sealed and dated, and public documents must be signed and dated in one of the three manners set out in A-E 2.02(7)(b).

The seal rule did not move in the 2024–2025 rewrite of the A-E chapters; it is still Wis. Admin. Code § A-E 2.02, and it is the only seal rule in the series — chs. A-E 3, A-E 4 and A-E 6, the registration chapters for architects, professional engineers and professional land surveyors, contain no seal provisions at all. What changed is its substance: CR 24-001 (Register July 2024 No. 823, effective 1 August 2024) added registered interior designers to the board, to its legal name and to the approved seal designs, and CR 24-028 (Register May 2025 No. 833, effective 1 June 2025) repealed and recreated § A-E 2.02(3), repealed § A-E 2.02(7)(a) outright and rewrote § A-E 2.02(7)(b). Separately, § A-E 2.02(8) lets plans prepared by an architect or professional engineer credentialed in another state be filed here only if a Wisconsin credential holder attaches a certificate — itself dated, signed and sealed — describing the review performed and accepting responsibility for supervision of construction; that route does not extend to land surveying. The section as published in Register June 2026 No. 846 still carries the 1⅝-to-2-inch diameter and the 1987 specimen artwork, and the only later change to ch. A-E 2 is CR 25-082, which created § A-E 2.03(5) on certificates of authorization effective 1 July 2026 and left § A-E 2.02 untouched. The wording “WISCONSIN” and “LANDSCAPE ARCHITECT” is fixed by the approved designs illustrated in A-E 2.02(2) rather than spelled out in the running text of A-E 2.02(1), which lists only name, credential number and city. A-E 2.02 was last amended by CR 24-028 (Register May 2025 No. 833, eff. 6-1-25), which repealed and recreated sub. (3) and rewrote sub. (7)(b), following CR 24-001 (Register July 2024 No. 823, eff. 8-1-24); the chapter as read is published in Register June 2026 No. 846.

Wisconsin landscape architect seal questions
Does a Wisconsin seal need your city on it?▾
Wisconsin is one of the few states that puts a place name on the face of the seal — A-E 2.02(1) requires the credential holder's city alongside the name and credential number. (Wis. Admin. Code § A-E 2.02(1))
How small can a Wisconsin seal be?▾
The diameter has a floor as well as a ceiling: a seal smaller than 1-5/8 inches does not comply, even if it is legible. (Wis. Admin. Code § A-E 2.02(1))
When can you seal only the title sheet of a bound set?▾
A bound volume may be signed, sealed and dated on the title or index sheet alone only if that sheet "identifies clearly all other sheets comprising the bound volume" — otherwise every sheet must be sealed. (Wis. Admin. Code § A-E 2.02(4), (5))
Does a revised sheet need to be resealed?▾
Revisions carry their own sealing duty: any addition, deletion or revision affecting public health and safety or a state or local code requirement must be signed, sealed and dated by whoever made or controlled it. (Wis. Admin. Code § A-E 2.02(6))
