In the event of a conflict between the provisions of this Article XIII and Note A in § 307-15A, the provisions of Note A in § 307-15A shall prevail.

Except as otherwise provided in this chapter, the lawful use of land existing at the time of adoption of this chapter or its predecessor may be continued although such use does not conform to the regulations specified by this chapter for the district in which such land is located; provided, however, that no such nonconforming use shall be extended to occupy a greater area of land than that occupied by such use at the time of the adoption of this chapter, nor shall any such nonconforming use be moved, in whole or in part, to any other portion of the lot or parcel of land occupied by such nonconforming use at the time of the adoption of this chapter or its predecessor; provided, further, that if any such nonconforming use of land ceases for any reason for any continuous period of one year or more, any subsequent use of such land shall be in conformity with the regulations specified by this chapter for the district in which such land is located.

Except as otherwise provided in this chapter, the lawful use of a building existing at the time of the adoption of this chapter or its predecessor or a structure as provided for in § 307-96 of this chapter, although such use does not conform to the regulations specified by this chapter for the district in which such building is located, may be continued.

If any nonconforming use of a building ceases for any reason for a continuous period of one year or more or if the building in or on which such use is conducted or maintained is moved for any distance, then any future use of such building shall be in conformity with the regulation specified by this chapter for the district in which such building is located. If any building in or on which any nonconforming use is conducted or maintained is hereafter removed, the subsequent location and use of any building thereon shall be in conformity with the regulations specified by this chapter for the district in which such land is located.

No existing building designed, arranged or intended for or devoted to a use not permitted under the regulations specified by this chapter for the district in which such building is located shall be enlarged, extended, reconstructed, structurally altered or moved unless such use is changed to a use permitted under the regulations specified by this chapter for the district in which said building is located; provided, however, that work may be done on ordinary repairs or on repairs or replacements of nonbearing walls, fixtures, wiring or plumbing.

A dimensionally nonconforming structure containing a conforming use may be enlarged, extended, reconstructed or restored as of right subject to the property owner obtaining all necessary permits, provided that such action would not increase the degree of any existing dimensional nonconformity nor create any new nonconformity with respect to the requirements set forth in this chapter. This provision only applies to residential uses.

The storage of goods or equipment in trailers, box trailers or similar vehicles, registered or unregistered, where not permitted by this chapter shall conform to the regulations of the zoning district in which it is located or shall be removed within one year of the effective date of this amendment.

Regardless of any other provision of this chapter, the owner of every builder's supply yard, contractor's yard or lumberyard which, after the adoption of this provision, exists as a nonconforming use in all districts shall apply to the Zoning Board of Appeals for a special permit to establish and maintain appropriate screening for such uses. Such screening may consist of topographic features, vegetation, solid walls or opaque fences and shall be maintained for as long as the nonconforming use continues. Such screening shall substantially conceal, in the judgment of the Zoning Board of Appeals, all operations of such builder's supply yard, contractor's yard or lumberyard throughout all seasons of the year from the view of pedestrians or motorists passing such use on any public or private street and from view of any existing or future residence within an R District and within 300 feet of such use.

Any use for which a special permit is required or for which a special permit may be granted as provided in this chapter, which use was existing at the time of the adoption of this chapter or its predecessor or was existing at the time of the adoption of any amendment thereto which designated the use as requiring a special permit, in any district in which such use is specifically permitted subject to the securing of a special permit and which use has continuously existed since that time, shall without further action be deemed to have been granted a special permit. Any expansion of such use shall require a special permit and site development plan approval subject to the provisions of Articles X and XII of this chapter.

All the foregoing provisions shall apply to all uses which do not conform to the provisions of this chapter at the time of its adoption and also to all uses that become nonconforming by reason of any subsequent amendment of this chapter.

Nothing in this chapter shall be deemed to require any change in the plans, construction or designated use of any building on which actual construction was lawfully begun prior to the adoption of this chapter and upon which building actual construction has been diligently carried on. "Actual construction" is hereby defined to be the actual placing of construction materials in their permanent position, fastened in a permanent manner, except that where a basement or cellar is being excavated, such excavating shall be deemed to be actual construction, or, where demolition or removal of an existing structure has been substantially begun preparatory to rebuilding, such demolition and removal shall be deemed to be actual construction, provided that actual construction work shall be diligently carried on until the completion of the building involved.

Every multifamily dwelling for which a building permit has been issued prior to the adoption of this chapter shall not be considered nonconforming for the purposes of Article XIII herein.

Preexisting structures, uses and other facilities as allowed in the R-80 Single-Family Residential Zone which were in existence at the time of the adoption of this amendment to the Zoning Ordinance shall be considered conforming.
