[Ord. 6/11/1975A, Art. III, § 23; as amended by Ord. 86-5, 1/14/1987]
Any lawful use of any dwelling, building or structure existing at the effective date of this chapter may be continued, even though such use does not conform to the provisions hereof. If no structural alterations are made, a nonconforming use of a building may be changed to another nonconforming use of a more restrictive classification. Whenever a nonconforming use has been changed to a more restrictive use or to a conforming use, such use shall not thereafter be changed to a less restrictive use. The nonconforming use of a building may be extended throughout those parts thereof which were manifestly arranged or designed for such use at the time of adoption of this chapter. No nonconforming building or structure shall be extended, or enlarged except when authorized by the Zoning Hearing Board which may permit one enlargement or extension up to 25% of the floor area of the structure as it existed at the time of passage of this chapter.
Whenever the use of a building shall become nonconforming through a change in the Zoning Ordinance or in the district boundaries, such use may be continued, and if no structural alterations are made, may be changed to another nonconforming use of the same or of a more restrictive classification.
A nonconforming use of a building or portion thereof which is hereafter discontinued for a continuous period of six months shall not again be used except in conformity with the regulations of the district in which such building is located.
A nonconforming building which has been damaged by fire, explosion, act of God or the public enemy to the extent of more than 60% of its reproduction value at the time of damage, shall not be restored except in conformity with the regulations of the district in which it is located. When damage is less than 60% of its reproduction value, a nonconforming building may be repaired or reconstructed, and used as before the time of damage, provided such repairs or reconstruction are completed within one year of the date of such damage.
Nonconforming mobile homes located on a lot in any district when once removed shall not be relocated on such lot and shall not be replaced with another mobile home.
