Building height limitations shall apply to all structures on the property, but shall not apply to chimneys, spires, gables, cupolas, standpipes, clock and other ornamental towers, conventional television antennas and similar, customary and necessary structures and mechanical appurtenances, atriums or vestibules, provided that no such exception shall cover at any level more than 10% of the applicable roof area nor shall the height of any such exception exceed the actual or maximum permitted height of the principal building, whichever is less, by more than 30%. In addition to the foregoing limitation, in the case of an exception for an atrium or vestibule, no other floor area other than the ground floor shall be permitted under such an atrium or vestibule and the total floor area of same shall not exceed 3% of the floor area of the ground floor of the principal building.

No part of a principal building shall extend into required or nonconforming yards except as follows: Open steps, stairways, front door, open canopies, and overhead awnings may extend not more than four feet; bay windows and open porches, balconies or terraces less than 15 feet wide may extend not more than two feet; and overhanging eaves, rainwater leaders, windowsills and other incidental, normal and customary building fixtures may extend not more than two feet. In no event shall any part of a principal building be located within five feet of any property line.

In residence districts, where single-family residential properties have nonconforming lot depths, the minimum required rear yard setback to the principal building may be reduced by 1/2 foot for each foot of lot depth deficiency, provided that no such rear yard setback shall be less than 30 feet, and further provided that the maximum allowable building height shall be reduced by 1/4 foot for every foot of reduction of the required rear yard setback.

In residence districts, where three or more existing neighboring residences form an established front setback line and where such properties are located on the same side of the street as, and within 500 feet of, a property on which a new residence is to be constructed, such new residence shall conform to such established line. Notwithstanding this provision, no new building shall be set back less than 30 feet from the front property line nor shall such building be required to be set back more than 50 feet from said property line.

Minimum yards specified in the Schedule represent minimum required building setback lines, as that term is defined in § 18A-5 of the Land Use Procedures Ordinance of the Township of West Caldwell.

Lot frontage shall not be less than 75% of the minimum required lot width.

"Max. Stories" specified in the Schedule shall be the maximum number of stories in a principal building when viewed from a front yard, and also when viewed from a side or rear yard if the principal building setback in such yard is deficient by more than 10%. For the purposes of this subsection, "Max.
