§ 7.8.4. Requirements for alterations, additions, or repairs.

(A)

Subject to the provisions of Paragraph (C) of this subsection, alteration, repair, or rehabilitation work may be made to an existing building or structure without requiring the entire building or structure to comply with all the requirements of this code, provided that the alteration, repair, or rehabilitation work conforms to the requirements of the code for new construction. However, if an existing building or structure is damaged by fire or otherwise requires repairs in excess of 50 percent of its replacement cost as proven by independent appraisal, the entire building or structure shall be made to conform to all current codes and Land Development Regulations for new buildings and current land use regulations. Additionally, any buildings or structure containing a nonconforming use must comply with current Land Development Regulations if required repairs exceed ten percent of the replacement cost of the structure or building as determined as noted above.

(B)

Additions to existing buildings must be made in conformity with current codes. However, existing buildings or structures need not be modified to comply with current codes except where the addition involves replacement or reconstruction of materials in the original structure or otherwise affects the safety or materials in the original structure. Any reconstruction or replacement materials or related repairs shall conform with current codes.

(C)

Whenever more than 25 percent of a roof covering is replaced within a 12-month period, the entire roof covering shall be made to conform with the requirements of the code for new buildings.

(D)

Repairs, alterations, and additions may not be made so as to extend or increase an existing nonconformity or hazard.
