Nothing in this section shall be deemed to prevent normal maintenance and repair of nonconforming structures. Reconstruction (as defined in the Uniform Construction Code) of a nonconforming structure requires conformance with current zoning regulations.

An addition of a nonconforming structure is permitted provided that such action does not increase or extend the degree of, or create any new, nonconformity with regard to the regulations pertaining to such buildings or the lot upon which they are constructed.

As an example, a dwelling which complies fully with all requirements except that it is closer to the street than the minimum required depth of a front yard may build an addition to the rear that does not encroach on the required rear yard.

It shall be lawful to raise a nonconforming structure which is below the base flood elevation requirements of the Borough, up to the base flood elevation requirement as long as the nonconforming structure is not otherwise expanded or relocated in such a manner as to increase or create a nonconformity. In so doing, the structure may be disconnected from all utilities without losing its protected status as a nonconforming structure.
