(a) Every registered architect shall have a seal of a design authorized by the board by rule. All technical submissions prepared by such architect, or under his or her direct supervision, shall be stamped with the impression of his or her seal. No architect holding a registration may impress his or her seal on any technical submissions unless they were prepared under his or her direct supervision: Provided, That in the case of the portions of such technical submissions prepared under the direct supervision of persons consulting with or employed by the architect, the architect may sign or seal those portions of the technical submission if the architect has reviewed such portions and has coordinated their preparation.
(b) No public official charged with the enforcement duties of a municipal building inspector may accept or approve any technical submissions involving the practice of architecture unless the technical submissions have been stamped as required by this section or by a registered engineer or the applicant has certified thereon the applicability of a specific exception under section twelve of this article permitting the preparation of such technical submissions by a person not registered thereunder. A building permit issued with respect to technical submissions which do not conform with the requirements of this section is invalid.
