316.2 Unsafe condition. Additions, repairs or alterations

shall not be made to an existing building or structure that will cause the existing building or structure to be in viola- tion of any of the provisions of this code, nor shall such additions or alterations cause the existing building or struc- ture to become unsafe, or to be in violation of any of the provisions of this code. An unsafe condition shall be deemed to have been created if an addition or alteration will cause the existing building or structure to become structurally unsafe or overloaded; will not provide adequate egress in compliance with the provisions of this code or will obstruct existing exits; will create a fire hazard; will reduce required fire resistance or will otherwise create conditions danger- ous to human life.

alternations or additions, which involves a change in use or occupancy, shall not exceed the height, number of stories and area permitted for new buildings

alterations shall not be made to an existing building or struc- ture when such existing building or structure is not in full compliance with the provisions of this code except when such addition or alteration will result in the existing building or structure being no more hazardous, based on life safety, fire safety and sanitation, than before such additions or alter- ations are undertaken.

316.5 Maintenance of structural and fire resistive integrity.

Alterations or repairs to an existing building or structure that are nonstructural and do not adversely affect any structural member of any part of the building or structure having required fire resistance may be made with the same materials of which the building or structure is constructed. The instal- lation or replacement of glass shall be as required for new installations.
