The only difference from the Texas architect seal is the arched top line. 22 Tex. Admin. Code § 3.102(b) requires the design to be “the same as the design of the sample seal shown in this Subsection except that the name of the Landscape Architect and the Landscape Architect’s registration number shall be substituted for the name and registration number shown on the sample seal.” The attached figure carries REGISTERED LANDSCAPE ARCHITECT arched across the top, STATE OF TEXAS across the bottom, a star at each side, your name in the inner ring and the Texas star at the center with the number beneath. A supplier who lets a template default to the architect legend has produced a device that matches no credential you hold.
Texas gives no unsealed option. Section 3.101 recognizes two lawful states for a document leaving your office: sealed, signed and dated under § 3.103(a), or labeled with your name and the date of issue and conspicuously marked not for regulatory approval, permitting or construction under § 3.103(b). An unmarked sheet is a violation on its own.
The size floor is one and one half inches with no ceiling, the same as the architect and registered interior designer seals, and the operative constraint is legibility on a copy. Section 3.102(a) requires a seal that “will produce a clearly visible and legible image of the seal when the document is copied or reproduced,” and forbids an impression or embossing seal on a document requiring a seal unless it meets that same test.

Is a seal required in Texas?
Occupations Code section 1052.152 states the duty: a landscape architect “shall maintain a seal as described by Section 1052.056 and shall stamp or impress the seal on each drawing or specification issued from the landscape architect’s office for use in this state.” Section 1052.056 has the Board prescribe and approve the seal, with the words “Registered Landscape Architect, State of Texas” in place of the Board’s own name. The working rules sit in 22 Texas Administrative Code chapter 3, subchapter F, which mirrors the architect subchapter: section 3.101 bars issuing a regulated document unless it is sealed, signed and dated under section 3.103(a) or labeled and marked not for regulatory approval, permitting or construction under section 3.103(b).
What must appear on the seal
- Registered Landscape Architect around the top of the outer band
- State of Texas around the bottom of the outer band
- Your name as registered, in the inner ring
- Your registration number, below the star
- The Texas star at the center of the seal
Section 3.102(b) is the same sentence as the architect rule with the profession changed: the design “shall be the same as the design of the sample seal shown in this Subsection except that the name of the Landscape Architect and the Landscape Architect’s registration number shall be substituted for the name and registration number shown on the sample seal.” The attached figure carries REGISTERED LANDSCAPE ARCHITECT arched across the top, STATE OF TEXAS across the bottom, a star at each side, the registrant name in the inner ring and the Texas star at the center with the number beneath. The only difference from the architect device is the top legend. Nothing may be added.
Size and shape
No smaller than one and one half inches in diameter. Section 3.102(b) sets the same floor as the architect and registered interior designer seals, with no ceiling. The operative constraint is legibility on a copy under section 3.102(a).
Embosser, rubber stamp or digital
Rubber stamp, impression seal or electronic image, with the reproduction test attached. Section 3.102(a) requires a seal that “will produce a clearly visible and legible image of the seal when the document is copied or reproduced” and forbids an impression or embossing seal on a document requiring a seal unless it meets that same test. Section 3.102(c) then allows a regulated document to be issued electronically or in any other format the landscape architect selects, and provides that the seal, signature and date of signing may be affixed electronically or by any other means “as long as the seal, signature, and date will produce a clearly visible and legible image on any copy or reproduction of the document to which they are affixed.” The safe buy is an inked stamp.
Signing and dating
Seal, signature and date, with the signature permitted across the seal. Section 3.103(a)(1) requires the seal, the signature “(across the face of the seal’s image or directly under or adjacent to the seal’s image)” and “the date of signing (including the month, day, and year) before the Construction Document is issued by or under the authority of the Landscape Architect.” Section 3.103(a)(2) requires all three to be clearly visible and legible on each copy and bars the signature and date from concealing or obscuring the name or registration number on the seal.
Same die, different top line, and the landscape rule spells out electronic sealing
The Texas landscape architect seal and the Texas architect seal come off the same template. Both are cut to a sample figure attached to the rule, both carry STATE OF TEXAS at the bottom, a star at each side, the registrant name in an inner ring and the Texas star at the center with the number beneath. The only difference is the arched top legend, REGISTERED LANDSCAPE ARCHITECT instead of REGISTERED ARCHITECT. A supplier who lets a template default to the architect legend has produced a device that does not match any credential the registrant holds.
Which documents must be sealed
Construction Documents, on the same sheet by sheet schedule as architects: each sheet of drawings or its electronic equivalent, each specification with the bound grouping and separately issued sheet rules, each sheet identifying the project and listing the sealed documents, and each drawing and specification forming part of an addenda, change order, construction change directive or other Supplemental Document. Work issued for any other purpose must instead carry the landscape architect’s name, the date of issue and a conspicuous statement that it is not for regulatory approval, permitting or construction.
Electronic and digital seals
Permitted, with no named technology. Section 3.102(c) is the whole of the electronic rule: electronic issuance is allowed, the seal, signature and date may be affixed electronically or by any other means, and the only test is that they produce a clearly visible and legible image on any copy or reproduction. No certificate authority, hash standard or product is named anywhere in chapter 3 subchapter F.
Renewal, lapse and retirement
Registration is annual and the seal carries no date, so renewal does not obsolete the device and the registration number does not change. Section 3.104 restricts use: the seal may be affixed only to documents prepared by the landscape architect or under the landscape architect’s Supervision and Control, only the landscape architect and persons with consent may use the seal, a copy of it or a replica of it, and once a Construction Document bearing the seal is issued the seal may not be removed. Section 3.103(c) requires the sealing landscape architect to maintain the sealed original or a legible copy for at least ten years from the date of signature. No surrender or destruction duty appears in subchapter F.
Firm requirements
Discretionary and not a seal element. Occupations Code section 1051.306 lets the Board require registration of a firm, partnership, corporation or association that practices architecture, landscape architecture or interior design, in the Board’s rulemaking discretion. Nothing in chapter 3 subchapter F puts a firm name or firm number on the seal; section 3.102(b) limits the face to the individual’s name and registration number.
What to check before you order
Order a circular seal at least one and one half inches across, cut to the sample figure attached to 22 Texas Administrative Code section 3.102(b): REGISTERED LANDSCAPE ARCHITECT arched across the top, STATE OF TEXAS across the bottom, a star at each side, your name as registered in the inner ring, the Texas star at the center and your registration number below it. Choose ink rather than a dry embosser, since the rule tests the image on a copy. Add no firm name, no expiration date and no extra lettering. If you seal electronically, the same image and the same legibility test apply.

Frequently asked questions
Is a seal required for landscape architects in Texas?
Yes. Occupations Code § 1052.152 requires a landscape architect to “maintain a seal as described by Section 1052.056 and shall stamp or impress the seal on each drawing or specification issued from the landscape architect’s office for use in this state.” Section 1052.056 has the Board prescribe and approve the seal, with the words Registered Landscape Architect, State of Texas in place of the Board’s own name, and the working rules sit in 22 Tex. Admin. Code chapter 3, subchapter F.
What has to appear on a Texas landscape architect seal?
Registered Landscape Architect around the top of the outer band, State of Texas around the bottom, your name as registered in the inner ring, the Texas star at the center, and your registration number below the star. Nothing may be added.
What size is a Texas landscape architect seal?
No smaller than one and one half inches in diameter, with no ceiling, under § 3.102(b). The same floor applies to the architect and registered interior designer seals. The operative constraint is the legibility test in § 3.102(a).
Can I use an embosser in Texas?
Only if it passes the copy test. Section 3.102(a) requires a seal that will produce a clearly visible and legible image when the document is copied or reproduced, and forbids an impression or embossing seal on a document requiring a seal unless it meets that test. An inked stamp is the safe buy.
Where does the signature go on a Texas seal?
Section 3.103(a)(1) allows the signature “(across the face of the seal’s image or directly under or adjacent to the seal’s image)” and requires “the date of signing (including the month, day, and year) before the Construction Document is issued by or under the authority of the Landscape Architect.” Section 3.103(a)(2) requires all three to be clearly visible and legible on each copy and bars the signature and date from concealing or obscuring the name or registration number on the seal.
Which Texas documents have to be sealed?
Construction Documents, on the same sheet by sheet schedule as architects: each sheet of drawings or its electronic equivalent, each specification with the bound grouping and separately issued sheet rules, each sheet identifying the project and listing the sealed documents, and each drawing and specification forming part of an addenda, change order, construction change directive or other Supplemental Document.
What if a Texas document is not for construction?
Then it has to say so. Section 3.103(b) requires work issued for any other purpose to carry the landscape architect’s name, the date of issue and a conspicuous statement that it is not for regulatory approval, permitting or construction. Section 3.101 recognizes only those two states, so an unmarked sheet is a violation in itself.
Can I seal electronically in Texas?
Yes, and the landscape architect rule is more explicit than the architect rule on this. Section 3.102(c) allows a regulated document to be issued electronically or in any other format you select, and provides that the seal, signature and date of signing may be affixed electronically or by any other means “as long as the seal, signature, and date will produce a clearly visible and legible image on any copy or reproduction of the document to which they are affixed.” No certificate authority, hash standard or product is named anywhere in subchapter F.
Who may use a Texas landscape architect seal?
Section 3.104 restricts it: the seal may be affixed only to documents prepared by the landscape architect or under the landscape architect’s Supervision and Control, only the landscape architect and persons with consent may use the seal, a copy of it or a replica of it, and once a Construction Document bearing the seal is issued the seal may not be removed.
How long do I keep a sealed Texas document?
At least ten years from the date of signature. Section 3.103(c) requires the sealing landscape architect to maintain the sealed original or a legible copy for that period, and the obligation runs with the person who sealed the document rather than with the firm.
Does a Texas landscape architecture firm number go on the seal?
No. Occupations Code § 1051.306 lets the Board require registration of a firm, partnership, corporation or association that practices architecture, landscape architecture or interior design, in the Board’s rulemaking discretion, but nothing in subchapter F puts a firm name or firm number on the seal. Section 3.102(b) limits the face to your name and registration number. Registration is annual and the seal carries no date, so renewal does not obsolete the device and the number does not change.
