Alterations or repairs to an existing building, structure, or sign which are non-structural, do not adversely affect any structural member or any part of the building, structure, or sign meeting required fire resistance standards, and do not involve the installation or replacement of glass may be made with the same material of which the building, structure, or sign was constructed, subject to approval by the building official.
C. Minor additions, alterations, or repairs to existing building service equipment which do not cause such existing building service equipment to become unsafe, unsanitary, and overloaded may be made in accordance with the standards in effect at the time the original installation was made, subject to approval of the building official.
