701A.3.2 Existing Structures. For existing structures, retrofitting of an element is required when more than 60% replacement of that element occurs. An addition to an existing structure need not comply with these standards if the addition does not exceed 60% of the floor are of the existing structure and the existing structure was not required to meet these construction standards when originally constructed. Retrofitting of an entire structure is required when a combination of elements are replaced or other repairs are made equal in value to 60% or more of the replacement cost of the structure as determined by the building official. Alterations made to a structure shall not increase the degree of non-conformity in regards to these standards.
