(B) Averaging setbacks.
(1) In a Residential District, if two or more of the lots on one side of the street between two intersecting streets are improved with buildings at the time of the passage of this chapter, the average of the distances that the street walls of such buildings are from the street line shall be the established building line for such block frontage; however, in no case will a setback of more than 25 feet be required.
(2) Where a residential lot adjoins a commercial district within the same block frontage, the front yard of any such residential lot, for a distance of not more than 50 feet from the district boundary line, shall not be required to have a depth of more than one-half the required depth of 25 feet.
(C) Visibility requirements. The following provides for the maximum safety of persons using sidewalks and streets.
(1) On any corner lot, no wall, fence, sign, or other structures, or plant growth shall be erected, placed, planted, or allowed to grow in such a manner as to materially impede vision between a height of two and one-half and ten feet above the centerline grades of the intersecting streets in the area bounded by the street lines of such corner lots and a line joining points along said street lines 20 feet from the point of the intersection.
(2) No foliage, shrubs, hedges, trees, or other obstructions shall be allowed in any street intersection or in any street within 20 feet of the street line of an intersecting street or within ten feet of any alley line.
(3) In any required front yard of any lot with a front driveway, except as provided in division (C)(1) above, no fence, wall, hedge, or yard ornament shall be permitted which materially impedes vision across such yard above the height of three and one-half feet.

No reduction in the size of a recorded lot below the minimum requirements of this chapter shall be permitted.
(2) Where there are existing recorded lots in a Residential District, which do not meet the minimum lot area requirement and are under separate ownership, single-family dwellings may be constructed as long as all other requirements, except lot size, are met.
(3) No accessory building shall be erected in any required yard and no separate or detached accessory building shall be erected within five feet of any other building.

(6) No dwelling shall be erected on, or moved to, a lot which does not abut on at least one street for at least 25 feet. 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.
(7) All buildings shall be located on lots so as to provide safe and convenient access for servicing, fire protection, and required off-street parking.
