      Boundaries indicated as approximately following the center lines of streets, highways, or alleys must be construed to follow center lines of rights-of-way or prescriptive easements. In case of closure of a street or alley, or vacation of an easement, the boundary must be construed as remaining at its prior location unless ownership of the closure or vacated area is divided other than at the center, in which case the boundary must be construed as moving to correspond with the ownership, but not beyond any previous right-of-way or easement line;
   2. 2.
      Boundaries indicated as approximately following platted lot lines must be construed as following lot lines;
   3. 3.
      Boundaries indicated as following County limit lines must be construed as following such County limits;
   4. 4.
      Boundaries indicated as following railroad lines must be construed to be midway in the right-of-way for such railroad lines;
   5. 5.
      Boundaries indicated as following bankfulls of bodies of water must be construed to follow such bankfulls. Boundaries indicated as approximately following the center lines of creeks, streams, rivers, canals, or other predominately linear bodies of water must be construed to follow such center lines;
   6. 6.
      Boundaries indicated as parallel to or concentric with, or extensions of features indicated in Paragraphs 1 through 5 above must be so construed;
   7. 7.
      Where areas appear to be unclassified on the Zoning Map, and classification cannot be established by the above rules, such areas must be considered to be classified AR-1 until action is taken to amend the Zoning Map;
   8. 8.
      Where territory is added to the jurisdictional area, such territory is classified as AR-1 until action is taken to amend the Zoning Map;
   9. 9.
      Distances and dimensions not specifically indicated on the Zoning Map must be interpreted from the Zoning Map by the Zoning Administrator and as so noted on the map;
   10. 10.
       Where natural or man-made features actually existing on the ground are at variance with those shown on the Zoning Map, the Zoning Administrator must interpret the district boundaries as so noted on the Zoning Map; and
   11. 11.
       Where uncertainties continue to exist and/or further interpretation is required beyond that presented in the above paragraphs, the Zoning Administrator is authorized to interpret the exact location of the boundaries or map features, at the request of an applicant or on the Zoning Administrator's own initiative.

3. C.

   2. 2.
      Where uncertainty exists as to Natural and Environmental Resources, the Zoning Administrator, in consultation with the Department of Building and Development, is charged with making necessary cartographic interpretations at the request of an applicant or on the Zoning Administrator's own initiative.

      1. a.
         The Zoning Administrator is authorized to interpret the exact location of the Natural and Environmental Resources if there appears to be a conflict between a mapped resource boundary, elevations, and actual physical conditions.
      2. b.
         The Zoning Administrator may require information from the applicant, including, but not limited to a topographic survey and/or engineering studies in conformance with the provisions of the Facilities Standards Manual.

Effective on: 1/1/1901

Purpose. Nonconforming uses, structures, and lots are incompatible with the Zoning Ordinance and the desired character of the County. As such, they are authorized to continue only under the circumstances provided in Section 1.03 until they are discontinued, removed, or changed to conform to the Zoning Ordinance. The purpose is to:

• Regulate and limit the development and continued existence of uses, structures, and lots legally established that do not conform to the requirements of the Zoning Ordinance;
• Meet the desired character of the County by improving nonconformities to a conforming status or otherwise eliminating the nonconformity;
• Permit the continued existence and improvement of certain historic resources; and
• Provide for the removal of nonconforming status through Special Exception approval by the Board of Supervisors.

1. A.
   Applicability. Section 1.03 applies to any nonconforming use, structure, or lot that was legally established but has become nonconforming due to:

   1. 1.
      The adoption of the Zoning Ordinance;
   2. 2.
      Any subsequent reclassification of zoning districts; or
   3. 3.
      Other amendment to the Zoning Ordinance.
2. B.
   Removal of Nonconforming Status. The Board of Supervisors may deem a nonconforming use, structure, or lot to be in compliance with the requirements of the Zoning Ordinance through approval of a Special Exception pursuant to Section 10.11.01. 

Effective on: 1/1/1901

1. A.
   Principal Use.

   1. 1.
      The protections and provisions of this section are only provided to nonconforming uses that are a principal use of the property or to parking as an on-site accessory use or structure. 
   2. 2.
      An accessory use cannot become a nonconforming principal use.
2. B.
   Expansion. A nonconforming use cannot be expanded or extended beyond the floor area or portion of the lot area that it occupied on the date the use became nonconforming.
3. C.
   Residential Expansion. Equivalent expansion of nonconforming residential uses is permitted when a nonconforming structure is expanded pursuant to Section 1.03.03.C.
4. D.
   Discontinuance.

   1. 1.
      If a nonconforming use is discontinued for a continuous period of more than 2 years at any time since becoming nonconforming, then that use cannot be renewed or reestablished.
   2. 2.
      Any subsequent use of the lot or structure must be in conformance with the Zoning Ordinance.
5. E.
   Change.

   1. 1.
      A nonconforming use may be changed to another nonconforming use only by approval of a Special Exception pursuant to Section 10.11.01.
   2. 2.

      When any nonconforming use is superseded by a permitted use, the use must thereafter conform to the regulations for the zoning district, and no nonconforming use may thereafter be resumed.

6. F.
   Conversion Condominium. Pursuant to Code of Virginia § 55.1-1905.E, a proposed conversion condominium that does not conform to zoning, land use, or Site Plan regulations must obtain Special Exception approval pursuant to Sections 10.11.01 and 10.11.10 prior to such property becoming a conversion condominium.  
7. G.
   Reduced Buffers, Setbacks, and Yards due to Highway Realignment or Condemnation.

   1. 1.
      Any use on a lot that has had its buffers, setbacks, or yards reduced through condemnation or realignment of a Federal or State highway to less than the requirements of the Zoning Ordinance is considered a nonconforming use subject to the provisions set forth in Section 1.03.02.G. 
   2. 2.
      The lost or reduced buffer need not be replaced as long as the use existing at the time of the loss or reduction is maintained.
   3. 3.
      When the use changes to a different use permitted in the zoning district and that use requires a buffer width greater than the previously existing use:

      1. a.
         The owner has the option to provide new or additional plantings in the existing reduced width if the Zoning Administer determines that the resulting buffer will provide equivalent buffering effect to one that would be required according to zoning district standards, except for the reduced width.
      2. b.
         In the event that the remaining buffer is less than 50% of the required width, the owner has the option to provide a buffer in an alternate location of choice if the Zoning Administrator determines it will achieve the intended buffering effect.
   4. 4.
      When the Zoning Administrator determines that the buffers proposed in accordance with Section 1.03.02.G do not provide adequate buffering, the owner must seek approval of a Minor Special Exception pursuant to Section 10.11.02 to change the use.

Effective on: 1/1/1901

1. A.
   Replace, Repair, or Reconstruction. Replacement, repairs (including structural repairs), restoration, and maintenance may be made to a nonconforming structure.

   1. 1.

      2. b.
         Damaged or destroyed by a casualty or event beyond the owner's reasonable control; and
      3. c.
         The degree of nonconformity is not increased; and
      4. d.
         Permits are obtained and construction is completed within 2 years of the removal or destructive event. An additional 2 years, for a total of 4 years, is granted if the destruction was due to a federally declared disaster.
   2. 2.
      A replacement structure must occupy the same footprint of the replaced, damaged, or destroyed nonconforming structure unless the new footprint complies with the setback requirements of this Zoning Ordinance.
   3. 3.
      Replacement of the nonconforming structure cannot include increased floor area either through an expanded footprint or additional height or stories.
2. B.
   Nonresidential Alteration or Enlargement. A nonconforming structure must not be enlarged, increased, nor extended to occupy a greater area of land than was occupied on the date the structure became nonconforming, except when such improvements do not increase the degree of nonconformity to any of the standards provided in Section 7.01.
3. C.
   Residential Alteration or Enlargement. Nonconforming residential structures may expand up to 50% of the existing square footage at the time the residential use became nonconforming, provided the setbacks that applied at the time the residential use became nonconforming are maintained.
4. D.
   Structure Moving. A nonconforming structure cannot be moved, in whole or in part, to any other location on or off the property unless every portion of such structure and its use is brought into conformity with all requirements of the Zoning Ordinance and the Codified Ordinances of Loudoun County.
