Every interior door shall fit reasonably well within its frame and shall be capable of being opened and closed by being properly and securely attached to jambs, headers or tracks as intended by the manufacturer of the attachment hardware.

The components of a structure and equipment therein shall be maintained in good repair, structurally sound and in a sanitary condition. These requirements shall apply to interior but not to exterior stairways, landings and balconies unless they are more than (ten feet) 10’ higher than the grade below. The code official may grant an administrative variance from this exterior requirement, on his own motion or on request of the property owner, so as to increase the ten feet (10’) height by up to 20%, if the facts are such that the code official makes the same written conclusions of fact that are required by Section 107.2(D) for variances.
