A Massachusetts landscape architect seal must reproduce the figure printed in 242 CMR 3.04(1), with your own name and registration number entered on it. The regulation sets the look, layout, size and wording through that figure instead of a written measurement, and it allows a rubber stamp, a metal embosser or an electronically generated image. This page covers the face, devices, sizing, sealed documents, signing and registration status.

Massachusetts is one row in our landscape architect seal requirements by state table, which sets each jurisdiction's rule side by side.
What goes on a Massachusetts landscape architect seal?
The figure printed in 242 CMR 3.04(1), completed with your own name and your registration number. Those two entries are the only personal content the rule lists. Everything else about the face follows the figure, which the seal has to match exactly.
Think of the figure as the specification sheet for your order. A reworded line, a rearranged layout or an added element would stop the seal from matching, so the real work before ordering is confirming the spelling of your name and each digit of your number. Our post on Massachusetts landscape architect stamp regulations walks through the same rule from a different angle.
Which devices does 242 CMR 3.04(1) allow?
Three. The seal may take the form of a rubber stamp, a metal embossing device or an electronically generated image. The regulation presents them as alternatives for one seal, so whichever you choose has to reproduce the same printed figure.
Choose by how your documents leave the office. An inked rubber stamp marks paper sets directly, an embosser leaves a raised impression, and an electronic image goes into files. If you keep more than one form, order each from the same face so the versions agree. Our article on the Massachusetts landscape architect stamp requirements adds background on choosing a device.
Can the seal be an electronic image in Massachusetts?
Yes. 242 CMR 3.04(1) lists an electronically generated image as a permitted seal, on equal footing with the embosser and the rubber stamp. It is one of the three named forms, not an exception carved out of them.
The image is the same seal in another medium, so it has to follow the printed figure just as a stamp does. Build it from the same face as any physical device you own. 242 CMR 3.04(3) speaks of stamped or embossed documents when it sets the signing and dating duty; signing and dating electronically sealed files as well keeps your practice consistent across paper and screen.
How large is the seal when the regulation gives no number?
Exactly as large as the printed figure. 242 CMR 3.04(1) ties the size to the figure in the regulation and never states a measurement in words, so the drawing, rather than an inch figure, determines how big your seal is.
That shapes the order in two ways. There is no dimension to quote to a maker, and there is no freedom to scale the face up or down to fit a title block, since a resized seal stops matching. The rule's text also names no shape, which is one more reason to work from the figure itself rather than from a description of it.
Which Massachusetts documents take the seal?
All plans, specifications and reports that you prepared or that were prepared under your supervision, under M.G.L. c. 112, § 100. The statute frames the duty around authorship and supervision rather than around any single type of drawing.
Specifications and reports need the same planning as a drawing set, because they often lack a title block. Decide before issue where the impression, your signature and the date will sit on them. For a broader view of the seal's role, see why the Massachusetts landscape architect stamp matters.
Do you sign and date each stamped document?
Yes. Under 242 CMR 3.04(3), any document you stamp or emboss must also carry your signature and the date. The duty follows the impression: whatever bears your seal gets both, with no exception for embossed work.
Give the signature and date a fixed spot in your title block so no sheet leaves the office stamped but unsigned. A reviewer can then confirm the impression, the signature and the date in the same place on every page, and you can check a set quickly before it goes out.
Can you keep sealing while your registration is not in full force?
No. M.G.L. c. 112, § 100 lets you use the seal only while your certificate of registration stays in full force. If it lapses, stop impressing the seal on plans, specifications and reports until the certificate is back in force.
The condition attaches to the certificate, not to the device. A stamp that still prints cleanly gives no permission by itself, so track the renewal date alongside your project deadlines. Our post on what a Massachusetts landscape architect seal means for your career looks at the seal's place in practice.
What should you send with a Massachusetts seal order?
Your name as it should read, your registration number and your device choice: embosser, rubber stamp or electronic image. Size, layout and wording are not options here, because the printed figure in 242 CMR 3.04(1) settles all three.
Copy the number from your certificate rather than from memory, since it is one of only two personal entries on the face. If you want several devices, list them on one order so each is made from the same artwork. An earlier post on applying for a Massachusetts landscape architect stamp covers the process side.
How do you proof a Massachusetts impression before first use?
Put a test impression beside the figure printed in 242 CMR 3.04(1) and compare them line by line. The size, the arrangement and the wording should match, and your name and registration number should read correctly with no missing characters.
For an embosser, look at the raised impression under low, angled light so shallow characters show. For an electronic image, print a sheet at the size you issue and run the same comparison. File the test sheet with your registration records so you have a reference for later checks.
Frequently asked questions
Can I add a firm name or logo to my Massachusetts seal?
Not if you want it to conform. 242 CMR 3.04(1) asks for an exact match with the printed figure, and the only entries it lists for you to supply are your name and registration number. Anything beyond those would be an addition to the figure.
Does the Massachusetts architect rule govern my landscape architecture seal?
No. Your seal follows 242 CMR 3.04(1), which names three device families. The Massachusetts architect rule is narrower and names a rubber seal only, so its device limit is not the one that applies to this seal.
Does an embossed seal still need a signature and date?
Yes. 242 CMR 3.04(3) reaches embossed documents as well as stamped ones, so a raised impression takes your signature and the date just as an inked impression does.
Which provision creates the duty, and which sets the design?
M.G.L. c. 112, § 100 says which documents carry the seal and makes its use depend on a registration in full force. 242 CMR 3.04(1) supplies the figure, the entries and the devices, and 242 CMR 3.04(3) adds the signing and dating duty.
Is a maker's proof enough to show my seal conforms?
Only after you compare it. The figure in 242 CMR 3.04(1) is the standard, not the proof, so check size, layout and wording against the regulation before you approve production.
With your name and registration number confirmed, choose an embosser, a rubber stamp or both from our Massachusetts stamps and seals collection.
