(1) Legally Existing Uses, Structures, Lots, Etc. Except as otherwise provided in this chapter, a Use, Structure, Lot, Sign, or Security Grill of any of the following types that legally existed as of the Effective Date of this chapter, any amendment of this chapter or any amendment to the Zoning Map, may be continued as a legal nonconformity in accordance with the provisions of this section and certification by the Zoning Administrator pursuant to § 345-803D:

(a) A lawfully permitted Use;
(b) A lawfully permitted Structure;
(c) A lawfully permitted Lot;
(d) A lawfully permitted Sign; and
(e) A lawfully permitted Security Grill.

(2) Proof of Nonconformity. The burden of establishing the prior existence of a nonconformity is on the applicant. When applying for any permit or approval related to a nonconformity, the applicant shall be required to submit evidence of a prior permit or other documentation showing that the nonconformity existed prior to the date on which it became nonconforming.
(3) Illegality. Any Use, Structure, Lot, Sign, or Security Grill that was illegal prior to the Effective Date of this chapter or the Zoning Map remains illegal if it does not conform to the provisions of this chapter or Zoning Map.
(4) Ordinary Maintenance or Repair. Notwithstanding any other provision of this chapter, Ordinary Maintenance or Repair may be done without affecting the lawful nonconforming status of a Use or Structure.

B. No Change in Nonconforming Use of Land. No Nonconforming Use may be enlarged, increased, or extended to occupy more land than that occupied by such Use on the Effective Date of this chapter, any amendment of this chapter, or any amendment to the Zoning Map, nor may any such Nonconforming Use be moved in whole or in part to any other portion of the Lot or parcel of land occupied by such Nonconforming Use at such time.
C. Cessation of Nonconforming Use of Land. If a Nonconforming Use of land, or any portion thereof, ceases for any reason for any continuous period of more than 12 months or is changed to a conforming Use, any future Use of the land must conform to the provisions of this chapter.
D. Nonconforming Use.

(1) Damage or Destruction of Structure. If any Structure used for a Nonconforming Use is damaged or destroyed by any means:

(a) To an extent of more than 50% of the Full Value of the Structure, no reconstruction or repairs may be made unless the Use of every portion of the Structure is made to conform to this chapter; or
(b) To an extent of 50% or less of the Full Value of the Structure, it may be reconstructed or repaired to its previous condition and the Nonconforming Use continued, so long as the nonconformity is not expanded, no new nonconformity is created, and if the reconstruction or repair is started within one year of such damage or destruction and is diligently pursued to completion.

(2) Extension of Nonconforming Use. Any such Nonconforming Use may be extended throughout any parts of the Structure that were manifestly arranged or designed for such Use as of the Effective Date of this chapter, any amendment of this chapter, or any amendment to the Zoning Map.
(3) Change to Another Use. If no Alterations are made, a Nonconforming Use may be changed to another Nonconforming Use which, in the determination of the Zoning Board of Appeals, either by general rule adopted on a request by the Planning and Economic Development Zoning Administrator or on a specific finding on appeal of a particular case, is of the same or of a more restricted nature.
(4) Cessation of Nonconforming Use. If any Nonconforming Use, in whole or in part, ceases for any reason for a continuous period of one year or more then the legal status of such Nonconforming Use shall terminate and any future Use of such Structure must conform to this chapter.
(5) Removal of Structure Used for Nonconforming Use. If any Structure in or on which any Nonconforming Use is conducted or maintained is removed, the subsequent Use of the land on which such Structure was located and the subsequent Use of any Structure thereon must be made to conform to this chapter.

(1) Damage or Destruction of Structure. If any Nonconforming Structure is damaged or destroyed by any means:

(a) To an extent of more than 50% of the Full Value of the Structure, no reconstruction or repairs may be made unless every portion of the Structure is made to conform to this chapter; or
(b) To an extent of 50% or less of the Full Value of the Structure, it may be reconstructed or repaired and the legality of the Nonconforming Structure continued, if the reconstruction or repair is started within one year of such damage or destruction and is diligently pursued to completion.

(2) Cessation of Use of Nonconforming Structure. If any Nonconforming Structure ceases to be in use for any reason for a continuous period of one year or more or is changed to a conforming Structure, or if the Structure is moved for any distance whatever, for any reason, then the legal status of such Nonconforming Structure shall terminate.
(3) Removal of Nonconforming Structure. If any Nonconforming Structure is removed, any subsequent Structure must conform to this chapter.

(1) Lots Subject to Conveyance. A Building Permit may be issued for the erection of a Structure on a Lot or other parcel for which a valid conveyance or contract of sale has been executed or delivered prior to the Effective Date of this chapter, or any amendment of this chapter, or any amendment of the Zoning Map, even though the area or dimensions of such Lot or parcel are less than that required by this chapter if:

(a) All other standards and requirements of this chapter are met; and
(b) The owner of such Lot or parcel does not also own or have other Lots or parcels contiguous thereto under option or contract to purchase as of the Effective Date of this chapter, any amendment of this chapter, or any amendment of the Zoning Map.

(2) Combination of Lots Required. In the case of § 345-901F(1)(b), such other Lots or parcels, or as much thereof as may be necessary, must be combined with the original Lot or parcel to make a single property, whereupon a Building Permit for the erection of a Structure may be issued if all other requirements of this chapter are met.

(1) Removal. Notwithstanding, anything to the contrary contained or implied in § 345-901A through § 345-901F, a Nonconforming Sign shall become an unlawful Sign and must be removed in accordance with this § 345-901: Nonconformities.

(b) Require immediate removal of such Sign and compensate the owner thereof for the fair market value of such Sign as of the Effective Date of this chapter, as determined by a qualified, independent appraiser selected pursuant to § 345-901: Nonconformities.
