Sec. 5.   Nonconforming Uses.
   A.   Definition. See Chapter 1, Article II, Definitions.
   B.   Existing Uses.  
      1.   General. Any lawful use of land or structures existing on the effective date of the adoption or amendment of these zoning regulations, but which would become a nonconforming use under the terms of these Regulations or future amendments hereto, shall be permitted to continue, subject to the provisions of this section pertaining to its extension, alteration, reconstruction, business tax renewal, discontinuance or change.
   Any use or structure in lawful existence at the time of adoption or amendment of these zoning regulations which would thereafter require a conditional use approval under its provisions shall be construed to be a nonconforming use. Such uses or structures may become conforming upon application, review, and approval as a conditional use according to the procedures and standards set forth in these zoning regulations for conditional use approvals. However, if approval of a conditional use is not granted for such use or structure, then it shall continue to be construed as nonconforming. Any enlargement, increase, extension, or intensification of a use or structure would require such approval as if it were a new use or structure. Any alteration or movement of such use which the Development Director finds does not enlarge, increase, extend, or intensify the use, shall not require conditional use approval, but shall conform to all other applicable provisions contained in the Boynton Beach Land Development Regulations.
      2.   Exclusions (Ordinance 12-010). Any legally conforming use with previous city approval or in possession of an active Business Tax Receipt and/or Certificate of Use at the time of this ordinance, but no longer listed as permitted or conditional in the zoning district in which it is located pursuant to Ordinance 12-010 shall continue to be considered conforming to the extent that it may expand business operations and/or associated building by up to twenty percent (20%), provided it does not expand onto an abutting lot. This same provision shall apply to the Land Use Option(s) of individual lots depicted on the Quantum Park Master Site Development Plan.
   C.   Nonconforming Use Limitations.
      1.   Use of Land. No nonconforming use of land shall be enlarged or increased, nor extended to occupy a greater area of land than was occupied on the effective date of the adoption or amendment of these Regulations, unless such use is subsequently changed to a use permitted in the district in which such use is located.
   No such nonconforming use shall be moved in whole or in part to any other portion of the lot or parcel occupied by such use on the effective date of the adoption or amendment to these Regulations, nor shall such nonconforming use be moved to any other parcel or located in any district within which said use is not permitted.
   No additional structures or buildings shall be erected in connection with such nonconforming use of land.
      2.   Use of Structures. Any nonconforming use which occupies a portion of a building or other structure not originally designed or intended for such use shall not be extended to any other part of the building or structure. No nonconforming use may be extended to occupy any land outside the building or structure, nor any additional building or structure on the same plat, which was not used for such nonconforming use at the effective date of the adoption or amendment of these Regulations.
   No structure used for a nonconforming use shall be enlarged, extended, reconstructed, or structurally altered, unless the use is changed to one which complies with the provisions of these Regulations. However, ordinary repairs, maintenance and improvements, such as plumbing or wiring, replacement of non-bearing walls, fixtures or other interior alterations, shall be permitted each year in an amount not to exceed twenty-five percent (25%) of the assessed value of the building or structure for that year as determined by the Palm Beach County Property Appraiser, subject to the provisions of the preceding paragraph and provided such work does not increase the cubic volume of the structure, the floor area devoted to the nonconforming use or the number of dwelling units. Nothing in these Regulations shall prevent compliance with applicable laws or ordinances relative to the safety and sanitation of a building occupied by nonconforming use.
   D.   Change of Use. Any part of a structure or land occupied by a nonconforming use which is changed to or occupied by a conforming use shall not thereafter be used or occupied by a nonconforming use. A nonconforming use of land or structure shall not be changed to any other use except one which would be permitted as a conforming use in the district in which the land or building is located. However, no change shall be required in the plans, construction, or designed use of any structure for which a building permit was lawfully issued pursuant to Chapter 4, Article IX, and upon which construction has actually begun prior to the effective date of the adoption or amendment of these Regulations.
   E.   Discontinuance. If for any reason a nonconforming use of land, structure or any part thereof ceases or is discontinued for a period of more than six (6) consecutive months, except when government action impedes access thereto, the land shall not thereafter be used for a nonconforming use. The issuance or existence of a required business tax receipt, permit, or other governmental authorization to conduct such nonconforming use shall not mean that the use has not ceased, but that the lack of the same shall create a refutable presumption that the use has ceased.
   F.   Nonconforming Lots/Structures. See Chapter 3, Article V, Section 11 for the regulations pertaining to nonconforming lots and structures.
   G.   Designated Historic Sites. The restrictions of this Section that limit the extension, alteration, reconstruction, business tax renewal, discontinuance or change of a non-conforming use of property do not apply to a property that is listed on the City's Register of Historic Places.
