1. Nonconformities may continue to be used and occupied, subject to regulations as to the maintenance of premises and conditions of operations set forth in this Article 6.B, or unless such nonconformity is terminated.
2. Nonconformities shall not be modified in any way that increases the degree of nonconformity.

1. Repairs necessary to maintain and to correct any damage or deterioration to the structural soundness of, or the exterior or interior appearance of, a building or structure without expanding the height or footprint of the building or structure, unless compliant with this UDC;
2. Maintenance of land to protect against and mitigate health and environmental hazards;
3. Repairs that are required to remedy unsafe conditions; and
4. Repairs necessary to comply with current building code requirements.

1. A nonconforming use may be extended throughout the same building or structure provided that:
   1. No structural alteration of the building (or portion of such building containing the nonconforming use in the case of buildings with multiple uses) shall be permitted;
   2. No additional dwelling units shall be permitted in the building;
   3. No additional nonresidential units and/or uses shall be permitted; and
   4. Such extension would not result in additional required parking.
2. Any existing occupied single-family dwelling unit that is deemed to be a nonconforming use may make improvements to the main and accessory structures so long as improvements do not increase the degree of nonconformity or increase the building height or building coverage.
3. No additional structure not conforming to the requirements of this UDC shall be erected in connection with the nonconforming use of land, building, or structure.
4. Whenever a nonconforming use of land, building, or structure has been discontinued for a period of six months, future use of land, building, or structure shall comply with this UDC. The Director may grant an extension if improvements that are necessary for the continuation of the nonconforming use are diligently pursued.

1. A nonconforming use that has been changed to a less nonconforming use pursuant to this subsection may not subsequently be changed back to a more nonconforming use.
2. A nonconforming use, if changed to a conforming use, may not subsequently be changed back to any nonconforming use unless otherwise permitted by this UDC. 

In addition to the standards in Article 6.B, nonconforming lots are subject to the additional standards in this Article 6.E.

1. A nonconforming lot that was made nonconforming by virtue of enactment of this UDC may be used for construction of a building allowed in the applicable zoning district; provided, that all other zoning district and dimensional standards are met.
2. In any district where single-family dwelling units are permitted, the setback requirements applicable in the zoning district shall apply, with the following exception: for single-family dwelling units on substandard width lots, an interior side setback may be reduced by half the lot width shortage provided such reduction does not exceed twenty-five percent (25%) of the required setback area width.

An illegal nonconformity exists when:

1. A nonconforming structure is destroyed or substantially destroyed or neglected by an intentional act of the owner or an agent without a proper permit. If this occurs, the nonconforming structure shall lose its nonconforming status and thereafter shall be required to be in conformity with existing codes. If a nonconforming use was in the destroyed or substantially destroyed structure, the nonconforming use and all site improvements shall lose their nonconforming status and be required thereafter to come into compliance with existing codes.
2. A use, building, or structure occurs to a nonconformity without being lawfully authorized in accordance with the provisions of this section. Such use and/or structure shall therefore cease all operations until such time that the required plans and/or permits are approved.
