Rule 11-2514 - ZONE DISTRICT BOUNDARY LINE CROSSING A LOT

2514.1

When a zone district boundary line divides a lot that was in single ownership on May 12, 1958, the permitted use and bulk of a structure located on that lot may be determined as follows:

(a) The allowable bulk for the portion of the lot located in a lesser restrictive use zone district may be increased by the bulk permitted on the portion of the lot located in a more restrictive use zone district; provided, that no portion of any structure permitted on the lesser restricted portion of the lot shall be extended to the more restricted portion of the lot;

(b) The calculation for determining additional bulk shall include only that portion of the lot in the more restrictive use zone district that is located within thirty-five feet (35 ft.) of the zone district boundary line;

(c) The additional bulk authorized in this section shall not exceed the maximum bulk permitted on the portion of the lot located in the lesser restrictive use zone district;

(d) For computation purposes, any portion of the lot located in an R-1 or R-2 District shall be deemed to be limited to a floor area ratio of four-tenths (0.4), any portion of the lot located in an R-3 District shall be deemed to be limited to a floor area ratio of six-tenths (0.6), and any portion of the lot located in an R-4 District shall be deemed to be limited to a floor area ratio of nine-tenths (0.9); and

(e) Except for accessory open parking facilities permitted elsewhere in this title, the portion of the lot located in a more restrictive use zone district shall be devoted only to required yards or courts or other open spaces.

2514.2

If approved by the Board of Zoning Adjustment as a special exception under § 3104, the regulations applicable to that portion of a lot located in a lesser restrictive use zone district that control the use, height, and bulk of structures and the use of land may be extended to that portion of the lot in a more restrictive use zone district; provided:

(a) The extension shall be limited to that portion of the lot in the more restrictive use zone district but not exceeding thirty-five feet (35 ft.);

(b) In authorizing an extension, the Board shall require compliance with § 2514.1(d);

(c) The extension shall have no adverse effect upon the present character and future development of the neighborhood; and

(d) The Board may impose requirements pertaining to design, appearance, screening, location of structures, lighting, or any other requirements it deems necessary to protect adjacent or nearby property.
