12 Where the District Council believes that a smaller lot is necessary, in order to make possible the redevelopment of a deteriorated or obsolescent single-family residential area.
13 The relationship between the percentage of the lot covered by multifamily dwellings and the amount of net lot area per dwelling unit shall be in accordance with the following table:
Percentage of Net Lot Area
Coverage by Multifamily DwellingsMinimum Net Lot Area per
Dwelling Unit (Square Feet)More than 11; not more than 12 1,400 More than 10; not more than 11 1,300 More than 9; not more than 10 1,200 More than 8; not more than 9 1,100 More than 7; not more than 8 1,000 7 or less 900 14 On a record lot having a net area of between ten thousand (10,000) and twenty thousand (20,000) square feet, a one-family detached dwelling may be erected, provided the lot was created (under the provisions of Section 24-111(b) of Subtitle 24 of this Code) from land previously subdivided in accordance with the Zoning Ordinance standards applicable to the R-R Zone on or before July 1, 1966.
15 (A) No variance of a lot size less than ten thousand (10,000) square feet (six thousand (6,000) square feet in the R-80 Zone) shall be considered except in (D) below.
(B) When two or more lots are combined to provide a single building site, the lots shall be consolidated in accordance with Section 24-108(a)(3) of the Subdivision Regulations prior to the issuance of a building permit so as to create a single lot, unless the residence is to be built on a portion of each of the existing lots.
(C) If a lot (or combination of lots) has a width of at least forty (40) feet, and was recorded prior to April 17, 1928, it can be used for a one-family dwelling provided the lot (or combination of lots) meets the minimum net lot area requirements of the appropriate zone.
(D) In Revitalization Tax Credit Areas or municipalities, a variance may be obtained to reduce the minimum lot size to five thousand (5,000) square feet.
(E) Until March 1, 2004, if a single owner combines lots, as provided in (B) above, to form at least thirty-five (35) buildable lots ten thousand (10,000) square feet or more in area, and if all such buildable lots are within one thousand five hundred (1,500) feet of one another and were unimproved on July 1, 2001, then the owner may combine lots for up to four combination lots which are seven thousand five hundred (7,500) square feet or more in area.
(F) If the original lot size was ten thousand (10,000) square feet but reduced in size due to a right of way taking or some other public purpose, the minimum lot size may be reduced to five thousand (5,000) square feet. Such reduction is not permitted where an adjacent lot in the same ownership may be combined with the lot under ten thousand (10,000) square feet to reduce or eliminate the area deficiency. Such reduction is not allowed unless a building permit has been obtained prior to July 1, 2003 except as provided in subsection (G). Buffering for adjoining properties shall be provided on each lot less than ten thousand (10,000) square feet.
(G) The minimum lot size may be reduced to five thousand (5,000) square feet in the R-R Zone if the original lot size was ten thousand (10,000) square feet but reduced in size due to a right-of-way taking for a lot which was the subject of approved variances, except lot size, and said variances were approved prior to the right-of-way taking. Any other lots under the same ownership shall be combined to achieve a lot that meets the 10,000 square foot standard.

(F) Is developed in accordance with the approved cluster development site plan.
19 For a lot shown on a record plat of subdivision approved pursuant to former Part 4A of this Subtitle prior to January 21, 1997, no minimum lot area is required.
(CB-84-1990; CB-47-1996)20 Same as would be applied to one-family detached dwellings, except public uses, for which no minimum lot area is required.
(CB-73-1994; CB-76-1995)21 Section 3 of CB-55-1996 reads as follows: "BE IT FURTHER ENACTED that the provisions of this Ordinance shall not apply to projects for which a Detailed Site Plan has been filed and accepted prior to November 1, 1996, provided the design guidelines and regulations not resulting in a requirement of resubdivision are applicable, and provided building permits for ten percent of the dwelling units included in the Detailed Site Plan are issued within one year of the effective date of this legislation (December 30, 1996), and extensions of time for the permits do not exceed six months, and that the dwelling units are constructed pursuant to the permits.
22 If the original lot size was greater than or equal to twenty thousand (20,000) square feet but reduced in size due to a right-of-way taking or for a stormwater management pond, the minimum lot size may be reduced to no less than ten thousand (10,000) square feet. Such reduction is not permitted where an adjacent lot in the same ownership may be combined with the lot under twenty-thousand (20,000) square feet to reduce or eliminate the area deficiency.

3 If the building is located less than sixty (60) feet from the side street line.
4 Where no lots (in the same block as the corner lot) front on the side street.
5 May be increased for certain purposes by approval of a Special Exception (Section 27-330).
6 If the building is located less than fifty (50) feet from the side street line.
7 On lots having a net area exceeding twenty thousand (20,000) square feet.
(CB-45-1987)8 May be increased to forty (40) feet with approval of a Special Exception, if the building is used for agricultural purposes and is erected on property (used for agriculture) containing at least five (5) acres.
9 Not over two (2) stories.
10 Accessory buildings, generally, shall be located only in the rear yard; however, on lots having no rear yard (through lots) and on corner lots where the designated front of the main building faces the side street, accessory buildings may be located in the yard opposite the designated front of the main building. In the R-H Zone, an accessory building may not encroach upon the minimum required yards. Accessory buildings associated with attached or multifamily dwellings may be located in any yard other than the one which the front of the dwelling faces, except that a guard booth may be located at the entrance to a development for which it provides security. A private parking garage accessory to a multifamily dwelling shall be subject to the setback regulations applicable to a main building in the zone in which it is located. The setback and height requirements of this table do not apply to dwellings which are accessory buildings, as addressed by Section 27-424.01. A detached garage accessory to a one-family detached dwelling may be located in a front or side yard adjoining a street, provided it was constructed prior to January 1, 1980.
(CB-110-1985, CB-129-1989; CB-65-1990; CB-36-1992)11 If the lots are used for one-family triple-attached dwellings, accessory buildings are limited to private automobile garages (one (1) per lot), storage sheds, pet shelters, and any agricultural accessory buildings shown on an approved Special Exception site plan. Garages on a corner lot may front on the side lot line, or may be attached to the rear of the main building. Private automobile garages may be attached or detached along side lot lines, and a pair of garages may be attached (back-to-back) to a similar pair along the rear lot lines. If the garage has access from the rear yard, the front of the garage shall be not less than twenty-five (25) feet from the nearest point of the main building. (See Figure 70.)
(CB-110-1985)12 In the R-20 Zone, when property abutting side and rear lot lines is also in the R-20 Zone, private parking garages may abut side and rear lot lines. In all other cases, the setback for private parking garages shall be the same as for any other accessory building.
(CB-129-1989)13 Includes accessory structures (for example, coops, runs, pens, hutches, and the like).
(CB-110-1985)14 A private parking garage accessory to a multifamily dwelling shall be subject to the maximum (but not the minimum) height regulations applicable to a main building in the zone in which it is located.
(CB-129-1989)15 Provided the use was in existence prior to June 30, 1987.
(CB-36-1991)16 These requirements do not apply to mobile homes used as accessory buildings that are in compliance with Section 27-424.04. For mobile homes used as accessory buildings that were previously used for agricultural storage purposes, the setback requirements in Table IV of this Section for mobile homes shall apply.
