IV-C - Existing buildings and land.

Except as hereinafter provided, this zoning ordinance shall not apply to structures or uses lawfully in existence or lawfully begun, or to a building or special permit issued before the first publication of notice of the public hearing on this ordinance but shall apply to any change or substantial extension of such use, to a building or special permit issued after the first notice of said public hearing, to any reconstruction, extension or structural change of such structure and to any alteration of a structure begun after the first notice of said public hearing to provide for its use for a substantially different purpose or for the same purpose in substantially different manner or to a substantially greater extent except where alteration, reconstruction, extension or structural change to a single- or two-family residential structure does not increase the nonconforming nature of said structure.

On Plum Island (which is a Barrier Beach), all new buildings shall be built on open pilings and shall comply with FEMA National Flood Insurance Regulations and State Building Code Regulations for elevation and flood proofing. All existing buildings with substantial improvements, and all horizontal expansions of the existing footprint, shall be built on open pilings and shall comply with FEMA National Flood Insurance Regulations and State Building Code Regulations for elevation and flood proofing. If a licensed engineer certifies that an existing portion of the solid foundation will not require modifications to support the proposed building (other than new pilings exterior to the existing footprint), the existing portion of the solid foundation may remain.

Notwithstanding the previous sentence, the existing solid foundation of a building shall be replaced with pilings, if, fifty (50) percent or more of the exterior walls have been removed, or are proposed to be removed, and a new roof will be constructed, or is proposed to be constructed.
