DISTRICTING RESOLUTION ANNOTATIONS

the square of the minimum depth of the rear yard as specified in terms of 

 its ratio to the depth of the lot. This would mean that in B districts with 

 a building 150 feet high, the depth of a rear yard would be 25 feet and the 

 area of an inner court would be 25 by 25 feet, or 625 square feet, but such 



Court A, opening 

 on street, would 

 often be too narrow 

 for its length, unless 

 part of street area, 

 as shown bu dotted 

 lines, is included.

an inner court would not have to be square. It might be any shape pro- 

 vided that it were not more than twice as long as it were wide for such 625 

 square feet. After the first 625 square feet were satisfied, however, any 

 additions might be made to the court as seemed desirable provided such 

 additions conformed to the rules for outer courts or side yards or offsets 

 as the case might be. A possible equivalent of a court 25 feet square would 

 be one a little over 18 by 36 feet. In a corner apartment house 15,0 feet 

 high, a rear inner court connecting with the street by a 10-foot side yard 50 

 feet long, would have to be 625 square feet but as the side yard is here 15 

 feet less than 65 feet long, 15 square feet for every 15 feet of height might 

 be deducted therefrom. This, for a 150-foot building, would equal 15 by 

 10 feet or 150 square feet, which deducted from 625 would leave 475 square 

 feet as the required area of the inner court, on the lot line. That would 

 bring it down to 15j4 by 31 as compared with 16 by 32 as required at the 

 same height for inner courts on the lot line under the Tenement House Law. 



Sec. 18, Par. (a). The provisions for skylights and projections beyond 

 the walls of yards and courts follow the Building Code. A special excep- 

 tion within 5 feet back from a street wall is made so as to allow cornices 

 or eaves to return their full width for architectural fitness. 



Sec. 18, Par. (b). The provisions with regard to fire-escapes, fire- 

 proof ouside stairways and solid-floored balconies to fire towers follow in 

 general the rulings of the Tenement House Department. As it is not desir- 

 able that fire-escapes, etc., should project 4 feet into an outer court no 

 allowance for the same is made. In a rear yard, however, the requirements 

 of other laws as to lattice enclosed fire-escapes demand a projection of at 

 least 7 feet 8 inches. Therefore, 8 feet were allowed. 



Sec. 18, Par. (c). A court corner might be cut off at an angle of 45 

 degrees, for example, and the length of the cut off might be as long as 7 

 feet, in conformity with the practice under the Tenement House Law. This 

 would not affect the size of yards and courts but would affect the percentage 

 of the lot that might be occupied. 



Sec. 18, Par. (d). The requirement for offsets in yards or courts is 

 intended to be virtually the same as it is in the Tenement House Law. Off- 

 sets could be shallower than they are wide but not deeper. It is not in- 

 tended, however, that this clause shall be used to increase the length of outer 

 courts.
