District of Columbia Interior Designer seal requirements: proper sizing, signing and sealing of documents
As of
The District licenses interior designers, and 17 DCMR § 3214 prescribes the seal: it must contain the licensee's name, his or her license number, and the words LICENSED INTERIOR DESIGNER-DISTRICT OF COLUMBIA. The rule directs the licensee to comply "in all respects, including size and format" with a specimen illustration reproduced in the rule, but the codified text states no diameter in figures. Interior design construction documents filed for a building permit must bear the seal, the licensee's name signed across the printed image of the seal — by manual or electronic signature — and the date on which they were sealed.
The "typically 1¾ inches" figure repeated for the District has no source in DC law; § 1516.4 states no dimension. DCRA, whose URLs still circulate for this board, ceased to exist on October 1, 2022 when it was split into the Department of Licensing and Consumer Protection and the Department of Buildings. Chapter 17-23 is not the engineering chapter. Section 3214 was published at 55 DCR 5441 (May 9, 2008) and amended at 59 DCR 9963, 9965 (August 17, 2012), the amendment adding the electronic-signature provisions in § 3214.6. On the official DCRegs section page the codified text is served as a downloadable document rather than displayed inline. The rule speaks of surrendering the seal to "the secretary of the Board"; the licensing body is now within the Department of Licensing and Consumer Protection.

District of Columbia interior designer seal questions
Does the District prescribe a diameter for the interior designer's seal?▾
Not in words. Section 3214.1 requires compliance "in all respects, including size and format" with a specimen reproduced in the rule, but the codified text carries no figure — the dimension exists only in the printed illustration, so any diameter quoted as a District requirement is being read off an image, not off the rule. (17 DCMR § 3214.1)
Is a sealed and signed drawing complete in the District?▾
Not quite. Beyond the seal, signature and date, § 3214.7 requires all plans, drawings, specifications or other instruments of service to be identified as interior design documents. (17 DCMR § 3214.7)
