The requirements and regulations specified in the regulations set forth in the title shall be subject to the additional requirements, exceptions, modifications and interpretations in this chapter.

Height limitations stipulated elsewhere in this title shall not apply to:

A.

Barns, silos, or other farm buildings or structures on farms, provided these are not less than fifty feet from every lot line; to church spires, belfries, cupolas and domes, monuments, water towers, fire and hose towers, masts and aerials; to parapet walls extending not more than four feet above the limiting height of the building; however, if, in the opinion of the zoning administrator, such structures would adversely affect adjoining or adjacent properties such greater height shall not be authorized except by the board of appeals;

B.

Places of public assembly such as churches, schools, and other permitted public and semi-public buildings not to exceed six stories or seventy-five feet, provided that, for each foot by which the height of such building exceeds the maximum height otherwise permitted in the district, its side and rear yards shall be increased in width or depth by an additional foot over the side and rear yard required for the highest building otherwise permitted in the district;

C.

Bulkheads, conveyors, derricks, elevator penthouses, water tanks, monitors and scenery lofts; to monuments, fire towers, hose towers, cooling towers, grain elevators, gas holders or other structures, where the manufacturing process requires a greater height; where a permitted use requires greater heights than specified, such may be authorized by the board of appeals.

A.

Front yard requirements do not apply to bay windows or balconies occupying in the aggregate not more than one-third of the front wall, provided that these projections come entirely within planes drawn from either main corner of the front wall, making an interior angle of twenty-two and one-half degrees in the horizontal plane with the front wall; to chimneys, flues, belt courses, leaders, sills, pilasters, uncovered porches, plantings, or similar features not over three feet above the average finished grade and distant five feet from every lot line.

B.

In any district where the average depth of two or more existing front yards on lots within six hundred feet of the lot in question and within the same block front or one thousand eight hundred feet is less or greater than the least front yard depth prescribed, front yards may be varied. The depth of the front yard on such lot shall not be less than the average of said existing front yards or the average depth on the two lots immediately adjoining, or, in the case of a corner lot, the depth of the front yard on the lot immediately adjoining; provided, however, that the depth of a front yard on a lot in any R district shall be at least twenty feet and need not exceed one hundred feet.

A.

Along any district boundary line, any abutting side yard on a lot in the less restricted district shall have at least a width equal to that required in the more restrictive district. Where a lot in an I or B district abuts a lot in an R district, the side yard shall be increased by three feet for each story that the building proposed on such lot exceeds the height limit of the R district.

B.

Side yards shall be increased in width by four inches for each foot by which the length of the side wall of the building, adjacent to the side yard, exceeds forty feet in any R-2 district.

C.

Side yards may be reduced by six inches from the otherwise required least width of each side yard for each foot by which a lot of record at the time of enactment of the ordinance codified in this title is narrower than the lot width specified for the district in which the lot is located, in the case of buildings not higher than two and one-half stories, and in case the owner of record does not own any adjoining property; provided, however, and irrespective of the provisions of subsection (F)(3) of this section, that no side yard shall be narrower at any point than six feet.

D.

Side yards may be measured to the centerline of adjoining alleys but in no case shall a building or structure for which a side yard is required be erected within ten feet of such alley.

E.

On a corner lot the least width of a side yard along the side street lot line shall be equal to the required front yard along the side street.

F.

Structures or projections into side yards may be permitted as follows:

1.

Fences, planting or walls not over six feet above the average natural grade;

2.

Fire escapes, three feet from side lot line. Bays and balconies not more than three feet from the building, provided these projections are entirely within planes drawn from either main corner of the side wall, making an interior angle of twenty-two and one-half degrees in the horizontal plane with the side; the sum of the lengths of such projections shall not exceed one-third of the length of the wall of the main building;

3.

Chimneys, flues, belt course, leaders, sills, pilasters and lintels, ornamental features, cornices, eaves, gutters and the like, into or over a required side yard not more than one and one-half feet;

4.

Terraces, steps, uncovered porches, stoops, or similar features, not higher than the elevation of the ground story of the building and distance three feet from a side lot line. (Amended by Ord. 637 (part), 1994)

A.

Rear yards may be reduced by six inches from the required least depth for each foot by which a lot at the time of enactment of the regulations codified in this title is less than one hundred twenty feet deep, in the case of a building not higher than two and one-half stories, and in case the owner of record does not own adjoining property to the rear; provided, however, that no required rear yard shall be less than forty feet deep.

B.

Rear yards may be measured to the centerline of adjoining alleys but in no case shall a building or structure be erected within twenty feet of such alley.

C.

Structures or projections into rear yards may be permitted as follows:

1.

Fences, planting or walls not over six feet above the average natural grade. Fire escapes, six feet. Bays and balconies, not more than three feet provided these projections are entirely within the planes drawn from either main corner of the rear wall, making an interior angle of twenty-two and one-half degrees in the horizontal plane with the rear wall. The sum of the lengths of such projections shall not exceed one-half of the width of the rear wall;

2.

Chimneys, flues, belt courses, leaders, sills, pilasters, lintels, ornamental features, cornices, eaves, gutters, and the like, into or over a required rear yard not more than one and one-half feet. (Amended by Ord. 637 (part), 1994)
