Indiana Landscape Architect seal requirements: proper sizing, signing and sealing of documents
As of
Indiana registers landscape architects, and IC 25-4-2-2(b) requires a board-authorised seal bearing the practitioner's name, certificate of registration number and the legend "Registered Landscape Architect State of Indiana". 804 IAC 1.1-2-7(d) sets the landscape architect seal at not less than 1 5/8 inches and not more than 1 7/8 inches in outside diameter, with a milled edge or two concentric circles. The seal must carry the registrant's original signature directly adjacent to it — expressly not across it — and goes on the title or cover page of specifications and on every sheet of drawings submitted for governmental review.
Indiana splits the three professions across three boards, all administered by the Indiana Professional Licensing Agency: engineers under 864 IAC 1.1, architects and landscape architects under 804 IAC 1.1, and surveyors under 865 IAC 1. Each of the three seal rules prescribes its design by incorporating a picture rather than by listing words, so the wording has to be read off the figure: all three figures carry "REGISTERED", "No." above a rule line, "STATE OF" and "INDIANA" inside the inner circle in addition to the profession wording in the outer band. The legend recorded here for each profession is the profession wording its own source fixes — "professional engineer" by statute for engineers, "registered architect" by statute for architects, and "LAND SURVEYOR" from the figure for surveyors, whose statute prescribes no wording at all. Only the surveyor rule regulates electronic signatures in detail — 865 IAC 1-7-4(c) demands unique identification, verifiability, direct control and a retained permanent digital copy — while the engineer rule accepts an electronic signature with no such conditions and the architect rule still speaks of the person's "original signature" beside the seal. Because 864 IAC 1.1-7-2, 1.1-7-3 and 1.1-7-4 were renumbered by the Legislative Services Agency as 865 IAC 1-7-1, 1-7-2 and 1-7-3 when surveyors were separated from the engineers' title, older material citing "864 IAC 1.1-7" for a surveyor's seal now points at the engineer rule; the code's chapter heading at IC 25-21.5-2 likewise still reads "State Board of Registration for Land Surveyors" even though IC 25-21.5-2-1 establishes the state board of registration for professional surveyors. Rule text here was read in the 2026 Edition of the Indiana Administrative Code and in the 2026 Indiana Code. Architects and landscape architects share one seal rule: 804 IAC 1.1-2-7 is captioned "Architect's seal", and subsections (a)–(c) govern the architect's seal while (d)–(f) govern the landscape architect's; subsections (g)–(l) apply to both. The rule was read in the 2026 edition of the Indiana Administrative Code as published by the Indiana General Assembly at iar.iga.in.gov — the edition the board's own in.gov page links to — and the statute in the official Indiana Code 2026 chapter file for IC 25-4-2 at https://iga.in.gov/ic/2026/Title_25/Article_4/Chapter_2.pdf.

- Affixing the seal and signature in any manner other than the one set out in 804 IAC 1.1-2-7 — whether done by the registrant or by someone to whom the registrant released custody of the seal — is aiding and abetting unlicensed practice, the conduct the rule calls "plan stamping".(804 IAC 1.1-4-6(e))

Indiana landscape architect seal questions
What do licensees most often get wrong about Indiana seals?▾
Can the signature run across an Indiana seal? No — 804 IAC 1.1-2-7(h) requires the original signature "directly adjacent thereto (not across the seal)", the opposite of the practice several neighbouring states allow. (804 IAC 1.1-2-7(h)) Does the "LA" prefix have to appear in the number on the seal? It may be excluded — the rule requires only that the name and registration number correspond to the name and certificate number on the certificate. (804 IAC 1.1-2-7(f)) Is one seal on the cover sheet enough? No — for work submitted for governmental review the seal and signature go on the title or cover page of the specifications and on each sheet of the drawings. (804 IAC 1.1-2-7(i))
