1 | Minimum lot width shall be measured at the building setback line; in no case shall a lot's width, as measured along its frontage, be less than 70% of that required at the building setback line. Lot widths required at the frontage shall be measured along a line paralleling the street line even if it is curvilinear. | |
2 | No townhouse grouping shall contain more than eight units. For each townhouse grouping containing more than four units, no more than 60% of such units shall have the same front setback; the minimum variation of setback shall be two feet. All townhouse buildings shall be set back a minimum of 15 feet from any parking facilities contained on commonly held lands. In those instances where several townhouse groupings are contained upon the same lot, the standards listed in the following footnote 3 shall apply. | |
3 | In those instances where several multiple-family dwelling buildings and/or townhouse groupings are located on the same lot, the following separation distances will be provided between each building: | |
A | Front to front, rear to rear, or front to rear, parallel buildings shall have at least 50 feet between faces of the building. | |
B | A minimum separation of 30 feet is required between end walls of buildings. | |
C | A minimum separation of 30 feet is required between end walls and front or rear faces of buildings. | |
D | No more than 16 units per multiple-family building shall be permitted. No more than eight units per townhouse grouping shall be permitted. | |
E | No more than 10 multiple-family dwelling units per acre shall be permitted. | |
4 | Within the R-4 Zone, single-family detached dwellings may employ a zero-lot-line design when the following conditions have been satisfied: | |
A | Minimum lot width shall be 30 feet building setback and the lot frontage. | |
B | One side wall of the structure may be located no less than one inch from one of the side lot lines when adjoining another zero-lot-line dwelling lot. The opposite side yard shall be at least 10 feet wide. | |
C | A perpetual six-foot wall-maintenance easement shall be provided on the lot adjacent to the zero-lot-line, which, with the exception of freestanding walls and/or fences, shall be kept clear of structures. This easement shall be shown on the plat and incorporated into each deed transferring title to the property. The wall shall be maintained in its original color and treatment, unless otherwise agreed to in writing by the two affected lot owners. | |
D | Roof overhangs may penetrate the easement on the adjacent lot a maximum of 24 inches, but the roof shall be so designed that water runoff from the dwelling place on the lot line is limited to the easement area. | |
E | The wall of a dwelling located along the zero-lot-line shall have no openings (e.g., windows, doors, air-conditioning units, vents, etc.), unless such openings are located at least eight feet above grade and have translucent panels. | |
F | No zero-lot-line shall abut a conventional single-family detached dwelling. | |
