Although a structure or building does not conform to the district regulations of this chapter for minimum lot size, lot width, yard requirements, height, lot coverage, parking, other characteristics of the structure or its location on the lot, the lawful existence of a structure or building on the effective date of this chapter may continue, subject to the following provisions:
A. Expansion of Nonconforming Building or Structure Prohibited. No nonconforming building, except when required by law, shall be enlarged, extended, reconstructed or structurally altered, unless the proposed expansion complies with the district regulations.

If an existing building was legally constructed prior to December 9, 1947 with less side yard than is now required, an addition to such building, which constitutes an extension of the side wall, shall be permitted, provided that such addition shall not encroach upon the front yard or rear yard as herein required.
C. Restoration of Destroyed Building. When a portion of a nonconforming building is destroyed by fire, explosion, natural causes or public enemy by more than 60 percent, said portion shall be restored only if it is done in a manner that conforms with the district regulations.
D. Relocation. No such building shall be moved for any reason for any distance whatever, unless it hereafter conforms to all provisions of the zoning district in its new location.
E. Modernization Permitted. Improvements or remodeling that do not increase the size or intensity of use shall be permitted.
