A. The following requirements are intended to provide exceptions or qualify and supplement, as the case may be, the specific district regulations set forth in this chapter:
1. An open space or lot area required for an existing building or structure shall not be counted as open space for any other building or structure. (1986 Code)
2. Fences, walls, and hedges in residential districts may be erected in any required yard, or along the edge of any yard, subject to section 12-441 of this part.
3. Where the dedicated street right of way is less than sixty feet (60'), the front yard building line shall be measured from the edge of the street easement.
4. No dwelling shall be erected on a lot which does not abut on at least one street for a distance of not less than thirty five feet (35'). A street shall form the direct and primary means of ingress and egress for all dwelling units. Alleys, where they exist, shall form only a secondary means of ingress and egress.
5. No minimum lot sizes and open spaces are prescribed for commercial and industrial uses. It is the intent of this chapter that lots of sufficient size be used by any business or industry to provide adequate parking and loading and unloading space required for operation of the enterprise.
6. On any corner lot on which a front and side yard is required, no wall, fence, sign, structure or any plant growth which obstructs sightlines at elevations between two feet six inches (2'6") and six feet (6') above any portion of the crown of the adjacent roadway shall be placed or maintained within a triangle formed by measuring from the point of intersection of the front and exterior side lot lines a distance of twenty five feet (25') along the front and side lot lines and connecting the points so established to form a right triangle on the area of the lot adjacent to the street intersection.
7. An attached or detached private garage which faces on a street shall not be located closer than twenty five feet (25') to the street easement line.
8. Unless first approved by the building official, no accessory building shall be constructed upon a lot until the construction of the main building has been actually commenced, and no accessory building shall be used unless the main building on the lot is also being used. (Ord. 1996-14, 11-21-1996)
