Except as otherwise provided in this section, any use, building, or structure existing at the time of enactment of this chapter may be continued, even though it is not in conformity with the regulations specified by this chapter.

If a nonconforming use of land or of a building or structure ceases or is discontinued for a continuous period of one year or more, subsequent use of such building, structure, or land shall be in conformity with the provisions of this chapter.

Any lawful nonconforming use of land exclusive of buildings and structures and the use contained therein may be extended upon the lot upon which it exists at the time of the effective date of this chapter, but such extension shall conform to area and lot regulations and to the design standards of this chapter. The extension of a nonconforming use on a lot shall be limited to the lot which was in existence on the effective date of this chapter.

Any nonconforming use may be expanded or altered through the obtainment of a special exception and subject to the following criteria, and those contained in Article VI:

Any nonconforming use may be replaced or substituted by another nonconforming use by special exception, with the following criteria and limitations:

Any lawful nonconforming building or other structure which has been involuntarily damaged or destroyed by fire, explosion, windstorm, or other similar active cause may be reconstructed in the same location, provided that:

It is the express intent and purpose of this chapter that if a building, structure, sign or land was expanded or extended to the limits of expansion for a nonconforming building, structure, sign or use of land as authorized by a prior zoning regulation or ordinance, no further expansion of said building, structure, sign or land shall be authorized. In the event a nonconforming building, structure, sign or use of land was expanded to a portion of the limits of expansion authorized by a prior zoning regulation or ordinance, additional expansion, if permitted by this chapter, shall only be authorized to the amount of expansion not previously utilized pursuant to said prior zoning regulation or ordinance.

On any lot of record which does not conform to the dimensional requirements of the zone in which it is located, a building may be erected, altered or used and any setback, yard, height and all other requirements, other than lot area, lot width or lot depth requirements, of this and all other applicable Township ordinances and regulations for the district in which the lot is located shall be met.

Any single-family dwelling that was legally in existence as of the effective date of this chapter, may be expanded, provided that such expansion does not result in a further encroachment into the yard setback requirement or exceed the lot coverage requirement within the zone, without obtaining a special exception or variance.

Any uses, structures or lots that become nonconforming because of a change in zoning district boundaries shall be regulated under this article on nonconformities.
