Section 11-C204. NONCONFORMING USE
-
204.1 A nonconforming use of land or structure shall not be extended in land area, gross floor area, or use intensity; and shall not be extended to portions of a structure not devoted to that nonconforming use at the time of enactment of this title.
204.2 Where the nonconforming use occupies only a portion of the structure, the restrictions in this section shall apply only to that part of the structure devoted to the nonconforming use.
204.3 A new structure shall not be constructed to contain a nonconforming use, and any addition to an existing structure containing a nonconforming use shall be devoted to a conforming use.
204.4 Discontinuance for any reason of a nonconforming use of a structure or of land, except where governmental action impedes access to the premises, for any period of more than three (3) years, shall be construed as prima facie evidence of no intention to resume active operation as a nonconforming use. Any subsequent use shall conform to the regulations of the zone in which the use is located.
204.5 This presumption may only be rebutted by objective proof of a continuing use or of affirmative steps taken to resume the use during the period of time identified by the Zoning Administrator when revoking an existing certificate of occupancy or denying an application for a replacement certificate of occupancy.
204.6 A nonconforming use that is discontinued for any reason for a period of three (3) years or less shall be allowed to resume operation provided there was no intervening confirming use, there are no changes to the non-conforming use and it conforms with Subtitle C § 204.1.
204.7 Ordinary repairs, alterations, or modernizations may be made to a structure or portion of a structure devoted to a nonconforming use. Structural alterations shall not be allowed, except those required by other municipal law or regulation; provided, that structural alterations shall be permitted to a lawfully existing, nonconforming flat or apartment house located in a Residential House (R) zone, or to a lawfully existing, nonconforming apartment house located in a Residential Flat (RF) zone.
204.8 A non-conforming use may be changed to a use permitted as a matter of right in the zone in which the property is located.
204.9 If approved by the Board of Zoning Adjustment, a nonconforming use may be changed to another nonconforming use, subject to the general special exception criteria of Subtitle X, Chapter 9, and the following conditions:
(a) The proposed non-conforming use would be permitted as a matter-of-right in the most restrictive subtitle in which the existing non-conforming use is permitted as a matter of right, in accordance with following order, from most restrictive to least restrictive subtitle:

(b) In the R, RF, or RA zones, the proposed use shall be either a single dwelling unit, flat, or a multiple dwelling unit development; except on an alley lot, the proposed use may only be a single dwelling unit;
(c) In the R and RF zones, the corner store provisions of the relevant subtitle shall apply;
(d) The external impacts of the proposed use will be deemed to be no greater than the existing use;
(e) The proposed use shall not adversely affect the present character or future development of the surrounding area within at least three hundred feet (300 ft.) of the site;
(f) The proposed use shall not create any deleterious external effects, including, but not limited to, noise, traffic, parking and loading considerations, illumination, vibration, odor, and design and siting effects;
(g) When an existing nonconforming use has been changed to a conforming or more restrictive use, it shall not be changed back to a nonconforming use or less restrictive use; and
(h) The Board of Zoning Adjustment may require the provision of changes, modifications, or amendments to any design, plan, screening, landscaping, type of lighting, nature of any sign, pedestrian or vehicular access, parking and loading, hours of operation, or any other restriction or safeguard it deems necessary to protect the value, utilization, or enjoyment of property in the neighborhood.
