BUILDING ZONE RESOLUTION 241 



(c) Chimneys or flues may be erected within a rear yard, provided they 

 do not exceed five square feet in area in the aggregate and do not obstruct 

 ventilation. 



(d) Except in A districts, where a building on an interior lot between 

 lots for which rear yards are_ required runs through the block from street 

 to street or to within 55 feet of another street, there shall be on each side 

 lot line above the sill level of the second story windows and in any case 

 above a level 23 feet above the curb level a court of at least equivalent area 

 at any given height to that required for an inner court at such height and 

 having a least dimension not less than that required for an outer court at the 

 same height. 



(e) When a proposed building is on a lot which is back to back with 

 a lot or lots on which there is a building or buildings having rear yards less 

 in depth than would be required under this article, the depth of the rear yard 

 of the proposed building shall not be required to be greater at any given 

 level than the average depth of the rear yards directly back to back with it 

 at such level, but in no case shall the depth of such rear yard be less at any 

 height than the least dimension prescribed for an outer court at such height. 



§ 17. Courts, (a) If a room in which persons live, sleep, work or 

 congregate receives its light and air in whole or in part directly from an 

 open space on the same lot with the building, there shall be at least one 

 inner court, outer court, side yard or rear yard upon which a window or 

 ventilating skylight opens from such room. Such inner court, outer court 

 or side yard shall be at least of the area and dimensions herein prescribed 

 for the area district in which it is located. Such rear yard shall be at least 

 of the area and dimensions herein prescribed for an inner court in the area 

 district in which it is located. In an A district, such inner court, outer court, 

 side yard or rear yard shall be at least of the area and dimensions herein 

 prescribed for a court in such district. The unoccupied space within the 

 lot in front of every part of such window shall be not less than three feet, 

 measured at right angles thereto. Courts, yards and other open spaces, if 

 provided in addition to those required by this section, need not be of the 

 area and dimensions herein prescribed. The provisions of this section shall 

 not be deemed to apply to courts or shafts for bathrooms, toilet compart- 

 ments, hallways or stairways. 



(b) The least dimension of an outer court, inner court or side yard at 

 its lowest level shall be not less than four feet, except that where the walls 

 bounding a side yard within the lot are not more than 25 feet in mean height 

 and not more than 40 feet in length, such least dimension, except in an E 

 district, may be not less than three feet. Where any outer court opens on 

 a street such street may be considered as part of such court. 



(c) The least dimension of an inner court at any given height shall be 

 not less than that which would be required in inches for each one foot of 

 height for a rear yard of the same height, except that an inner court of 

 equivalent area may be substituted for said court, provided that for such 

 area its least dimension be not less than one-half of its greatest dimension. 

 If an inner court is connected with a street by a side yard for each one foot 

 that such side yard is less than 65 feet in depth from the street, one square 

 foot may be deducted from the required area of the inner court for each 

 15 feet of height of such court. If the lot is not required under this resolu- 

 tion to have a rear yard, an outer court, not opening on a street, shall open 

 at any level on an inner court on the rear line of the lot and such inner court 

 shall be deemed a rear yard in such case.
