Residential buildings or structures. Any existing one- or two-family residential building or structure or building accessory thereto made noncomplying as to bulk by this chapter or any amendment thereof shall be permitted to comply with the yard and bulk requirements as specified for the most restrictive residential district having the same or less lot width. The lot itself shall then have the yards and bulk requirements for that district. No front yard may in any event be closer to the designated street line than the established setback, except where the established setback exceeds the required front yard.

Nonresidential buildings or structures. Normal maintenance and repair, structural alteration in or reconstruction or enlargement of a building or structure with noncomplying bulk is permitted if the same does not increase the degree of or create any new noncomplying bulk in such building or structure.

Two or more adjoining noncomplying subdivision lots, regardless of ownership, in a subdivision approved by the Planning Board shall have three years from the date of filing with the office of the County Clerk to obtain a building permit. Two or more adjoining noncomplying lots in a subdivision approved by the Planning Board and filed with the office of the County Clerk more than three years prior to the effective date of this chapter and in the same ownership shall not be eligible to receive a building permit. Said subdivision or part thereof shall be resubmitted to the Planning Board for approval in accordance with the applicable provisions of this chapter. Any lot in a subdivision approved by the Planning Board after the effective date of this chapter, but which is made noncomplying as to bulk by any future amendments of this chapter, shall have three years from the date of filing to obtain a building permit.

A lot shall not be considered noncomplying with respect to the front requirements of this chapter if said condition is the result of a street right-of-way widening reservation or dedication, whether in fee or easement, required by the Planning Board at the time of subdivision or site development plan approval.

Repair and alterations. Normal maintenance and repair of a building or structure is permitted if it does not extend the nonconforming use. No extension, alteration or enlargement shall be made in a building or structure occupied by a nonconforming use, nor in a nonconforming nonbuilding use except:

Change of nonconforming use. Any lot on which a lawfully nonconforming use has been conducted shall not be used for any other nonconforming use. A nonconforming use shall not be expanded or extended above the level or intensity at which such use existed on the date in which it became nonconforming, except as may be permitted in Subsection A above and Subsection D below. A nonconforming use may be changed to a conforming use permitted in the underlying zoning district and the use of a dimensionally nonconforming building or structure may also be changed to a conforming use without impacting the dimensionally nonconforming status of such building or structure, but which change in use shall be subject to the use provisions of this chapter, as well as the standards for the granting of conditional use permits, special permits and/or site development plan approval. No nonconforming use, building or other structure, once changed to conform with the requirements and standards of this chapter, shall thereafter be changed so as to be nonconforming again.

Cessation of use. If active and continuous operations are not carried on in a nonconforming use during a continuous period of one year, the building or land where such nonconforming use previously existed shall thereafter be occupied and used only for a conforming use. Intent to resume active operations shall not affect the foregoing. The time period set forth herein shall be tolled for any cessation of use pursuant to a court order.

Permitted extension or enlargement shall mean and shall be subject to site development plan approval:

Damage and destruction. A building or structure occupied by a nonconforming use or which is dimensionally nonconforming, which is damaged by fire or other causes to the extent of 75% of last full market value as shown in the records located in the Town Assessor's office, excluding the assessed valuation of the land thereof, shall not be repaired or rebuilt except in conformity with the requirements of this chapter. Any such building, structure or any part thereof which is damaged to an extent less than 75% of last full market value as shown in the records located in the Town Assessor's office, excluding the assessed valuation of the land, may be repaired but not enlarged or extended except in conformity with the use and bulk requirements of this chapter, provided that a building permit is obtained within one year after such damage; otherwise such building, structure or part thereof shall thereafter be occupied only by a conforming use and shall comply with the bulk requirements of this chapter.
