(A) The Codes Appeal Board, when so appealed to and after a public hearing, may vary the application of any provision of a Technical Code to any particular case when, in its opinion, the enforcement thereof would do manifest injustice and would be contrary to the spirit and purpose of such code or the public interest, or when, in its opinion, the interpretation of the officer appealed from should be modified or reversed.
(B) A decision of the Codes Appeal Board to vary the application of any provision of a Technical Code, or to modify any notice or order of the officer appealed from, shall specify in what manner such variation or modification is made, the conditions upon which it is made, and the reasons therefor; provided, that in varying the application of any provision of any Technical Code or in modifying any notice or order of the officer appealed from, affirmative votes of three members shall be required. No member of the Board shall pass upon any question in which he or she, or any corporation in which he or she is a shareholder, is interested.
