A nonconforming use shall be presumed to be abandoned when there occurs a cessation of such use or activity by an apparent act or failure on the part of the tenant or owner to reinstate such use within a period of one year from the date of cessation or discontinuance. Such use shall not thereafter be reinstated and the structure shall not be reoccupied except in conformance with this chapter.
Any nonconforming building or use which has been destroyed by fire, explosion, flood, windstorm, or other act of God shall be considered partially destroyed if the cost of restoration equals one-half or less than one-half of the estimated true value of the building as shown on the latest tax assessment records as determined by the Tax Assessor and such building or use may be rebuilt, restored, or repaired not to exceed the area of the building prior to its destruction.
No nonconforming use shall, if once changed into a conforming use, be changed back again into a nonconforming use.
A nonconforming building may be altered, but not enlarged or extended, during its life to an extent not exceeding in the aggregate 50% of the assessed value as recorded in the records of the Tax Assessor, unless said building is changed to a building conforming to the requirements of this chapter.
Notwithstanding the above, for all existing principal residential structures that are being raised in conformance with Chapter 22 or pursuant to a variance granted under Chapter 22, excepting new construction or additions, those structures may maintain pre-existing nonconformities.
