(225 ILCS 310/4.1)

(Section scheduled to be repealed on January 1, 2027)

Sec. 4.1. Seal. Every registered interior designer shall have a reproducible seal, or facsimile, the impression of which shall contain the name of the registered interior designer, the registration number, and the words "Registered Interior Designer, State of Illinois". The registered interior designer shall affix the signature, current date, date of registration expiration, and seal to the first sheet of any bound set or loose sheets of interior technical submissions used as contract documents between parties to the contract or prepared for the review and approval of any governmental or public authority having jurisdiction by that registered interior designer or under that registered interior designer's responsible control. The sheet of interior technical submissions in which the seal is affixed shall indicate those documents or parts thereof for which the seal shall apply. The seal and dates may be electronically affixed. The registrant may provide, at the registrant's sole discretion, an original signature in the registrant's handwriting, a scanned copy of the document bearing an original signature, or a signature generated by a computer. All interior technical submissions issued by any corporation, partnership, or professional service corporation shall contain the corporate or assumed business name in addition to any other seal requirements set forth in this Act.

A registered interior designer under this Act shall not sign and seal interior technical submissions that were not prepared by or under the responsible control of the registered interior designer, except that:

(1) the registered interior designer may sign and seal those portions of the interior technical submission that were prepared by or under the responsible control of a person who holds a registration under this Act, and who has signed and sealed the documents, if the registered interior designer has reviewed in whole or in part such portions and has either coordinated their preparation or integrated them into the work;

(2) the registered interior designer may sign and seal portions of the professional work that are not required by this Act to be prepared by or under the responsible control of a registered interior designer if the registered interior designer has reviewed and adopted in whole or in part such portions and has integrated them into the work. The work associated with the combination of services in connection with the design and construction of buildings shall be provided by a licensed architect. If engineering, structural engineering, or licensed land surveying services are required in association with an interior nonstructural project being performed by a registered interior designer, the documents that have already been properly sealed by a licensed professional engineer, licensed structural engineer, or licensed land surveyor may be compiled by a registered interior designer. Each design professional shall seal the respective documents and shall not seal a document that was not prepared under the design professional's responsible charge. For all other projects, engineering, structural engineering, or land surveying services shall be procured separate from the registered interior designer;

(3) a partner or corporate officer of a professional design firm registered in this State who has professional knowledge of the content of the interior technical submissions and intends to be responsible for the adequacy of the interior technical submissions may sign and seal interior technical submissions that are prepared by or under the responsible control of a registered interior designer who is registered in this State and who is in the regular employment of the professional design firm.

The registered interior designer exercising responsible control under which the interior technical submissions or portions of the interior technical submission were prepared shall be identified on the interior technical submissions or portions of the interior technical submissions by name and Illinois registration number.

Any registered interior designer who signs and seals interior technical submissions not prepared by that registered interior designer but prepared under that registered interior designer's responsible control by persons not regularly employed in the office where the registered interior designer is a resident shall maintain and make available to the Board upon request for at least 5 years following such signing and sealing, adequate and complete records demonstrating the nature and extent of the registered interior designer's control over, and detailed professional knowledge of the interior technical submissions throughout their preparation.
