The lawful use of land, buildings, or structures existing when this chapter was adopted may be continued although they may not conform to this chapter provided, however, that none shall be enlarged, extended, relocated, converted to another use, or altered, except in conformity with this chapter, except as permitted below.

[1969 Code § 88-35; Ord. No. 1978-6]
A nonconforming use shall be considered abandoned: a. if it is terminated by the owner; b. if a nonconforming use involving a building or structure is discontinued for 12 consecutive months; or c. if a nonconforming use of land not involving a building or structure is discontinued for a period of six months. The subsequent use of the abandoned building, structure and/or land shall be in conformity with this chapter.
[1969 Code § 88-36; Ord. No. 1978-6]

a. 
Any nonconforming building, structure or use which has been condemned or damaged by fire, explosion, flood, windstorm, or act of God, shall be examined by the following three people: a. the Construction Official; b. the owner or an architect or engineer selected by the owner; and c. a third person agreed to by the Construction Official and the owner whose fee shall be agreed to and shall be paid in equal portions by the Borough and the owner. If in the opinion of the majority of the above three people, the value of repairing the condition is greater than 50% of the value of replacing the entire structure, it shall be considered completely destroyed and may be rebuilt to the original specifications only upon approval of a use variance as provided by State statues.
b. 
Where the value of repairing the condition is determined to be less than 50% of the value of replacing the entire structure, the nonconforming structure or use may be rebuilt and used for the same purpose as before, provided it does not exceed the height, area and volume of the original structure.
c. 
The percent damaged shall be the current replacement costs of the portion damaged or condemned computed as a percentage of the current total replacement cost of the entire structure, neither to include the cost of the foundation.
[1969 Code § 88-38; Ord. No. 1978-6]
Repairs and maintenance may be made to a nonconforming use, structure, or lot provided the repair and maintenance work do not change the use, expand the building or the functional use of the building, increase the area of a lot used for a nonconforming purpose, or increase the nonconformity in any manner.
[1969 Code § 88-39; Ord. No. 1978-6]
Any nonconforming use, structure or lot may be sold and continue to function in the same nonconforming manner.
