A. 
A nonconforming use is an activity which was present on a property before this chapter was adopted but is not listed as a permitted use for the zone district in which the property is located. A nonconformity may later be created by an amendment to the zoning text or map, but in no other manner.
B. 
A nonconforming structure is one that was constructed on its property before adoption of this chapter with its setback from one or more property lines less and/or height greater than the standards established for the zone district containing the property.
A. 
A nonconforming use may be expanded by 25% beyond the area on the ground it occupied when this chapter was adopted but not onto land acquired by the owner of the use after adoption of this chapter. A nonconforming structure may be expanded by 25% in volume over the volume of the structure when this chapter was adopted. In neither case shall such expansion occur outside the setback lines within the property. A nonconforming use may be expanded to occupy all of a structure it occupied in part when this chapter was adopted but then may not be further expanded.
B. 
If a nonconforming use is discontinued for a period of at least one year for any reason, any use of the property thereafter shall be in conformance with the development regulations for the zone district containing the property. If the owner of the nonconforming use claims the one-year period is too short because of financial, health or other hardship, he may appeal to the Zoning Hearing Board for an extension not to exceed one additional year. Discontinuance of a nonconforming use shall be indicated by the removal of stock-in-trade and/or permanent equipment or furniture needed to operate the use.
C. 
A nonconforming use may be changed to a second nonconforming use, provided that an application for the second use is filed with the Zoning Hearing Board and the Board finds that the proposed use is more compatible with the uses permitted in the zone district than the preceding nonconforming use.
D. 
A nonconforming use may be sold by one owner to the next but each succeeding owner of a nonconforming commercial or industrial use shall receive approval of the Zoning Officer before commencing operation to assure that the use will be operated in the same manner as formerly.
E. 
Once a nonconforming use is changed to a conforming use it may not thereafter revert to nonconforming status. If a nonconforming use occupies a building and is discontinued any nonconforming use of the property shall also cease.
A. 
No structure shall be enlarged or altered to create a nonconformity or increase an existing nonconformity except in compliance with § 180-32A above.
B. 
Replacement of a nonconforming structure shall be done with respect to the setback and height requirements for the zone district containing the property, except that if the owner alleges a hardship he may petition the Zoning Hearing Board to grant approval of replacement on the foundation of the building to be replaced but in no case in a location more nonconforming than the original location.
A. 
The Zoning Officer shall identify and record all uses of land and buildings in the Township made nonconforming by adoption of this chapter. All uses that are not permitted by right or are not conditional uses in a particular zone district shall be considered as nonconforming.
B. 
The Zoning Officer shall keep the record current as amendments to this chapter create new nonconforming uses and as removal of buildings and uses eliminates nonconforming uses.
C. 
The record may be kept by map or written documentation.
