The following provisions shall be considered supplementary to or modifications of all other yard requirements set forth in this chapter.
(A) Yards and other buildings. No part of a yard or other space required about any building for the purpose of complying with the provisions of this chapter shall be included as a part of a yard or other open space similarly required for another building.
(B) Front yard. In residential and in office and institutional zones where lots comprising 25% or more of the frontage on the same street and within the same block and zone district are developed with buildings having an average front yard with a variation in depth of not more the eight feet, no building hereafter erected or structurally altered shall project beyond the average front yard so established; provided, this section shall not be so constructed as to require a front yard depth of more than 45 feet; provided, further, that no front yard depth need exceed the average provided for the two adjoining buildings, one on either side thereof, if such two adjoining buildings are less than 200 feet apart.
(C) Side yards on corner lots. In residential zones the minimum width of the side yard along an intersecting street shall be one-half the required front yard; accessory buildings in the rear yard shall also comply with this requirement.
(D) Building appurtenances in required yards.
(1) Cornices, eaves, steps, gutters, bay windows less than ten feet wide, fire escapes, fire balconies, fire towers and similar features may project not more than two and one-half feet into any required yard.
(2) Subject to the provisions of § 153.012, necessary retaining wall, fences less than four feet high and fences less than six feet high when located in a rear yard, shall be exempt from the yard requirements of this chapter. No fence more than four feet in height shall be permitted in a front yard. On a corner lot no fence more than four feet in height shall be located within any yard required along a street line by any other provision of this chapter. The height of any fence located within a yard abutting a street line shall be measured from the sidewalk; and if there be no sidewalk or curb, from the center line of the street. All other fence heights shall be measured from natural grade.
(3) Terraces, steps and uncovered porches which are not in any part more than four feet above the ground floor level and not within two and one-half feet of any party lot line shall be exempt from the yard requirements of this chapter.
(E) Yards and building setback lines. Where any required yard abuts a street upon which an official building setback line has been established by the town, such building setback line shall be considered the property line for the purpose of measuring the depth of required yards.
