subtracted from each of these least dimensions as the yard may start 23 

 feet above the curb. 



An outer court at 150 feet in height at the top will be 12' ■ feet in 

 least dimension, but if its length is more than eight times its width., it will 

 have to be widened out somewhat at the open end. At 90 feet in height, 

 such outer court will have to be 7'_- feet in width. If in a building 150 

 feet high, where an outer court would normally have to be 12 r _• feet wide, 

 the court, instead of being eight times, is not over four times as long as it 

 would have to be wide — that is, not over 50 feet long — then it could be 6 

 inches narrower for every 24 feet of height or 3 feet narrower fur a 

 building between 144 and 168 feet high. This would firing down such 

 width to what is required under the Tenement House Law. By the same 

 rule the side yard required under the Tenement House Law may be reduced 

 from I2y 2 feet to the 10 feet required in that law provided such yard is not 

 more than 50 feet in depth from the street. (See Figure 151.) 



Inner courts, whether on the lot line or not, will be about half way be- 

 tween the required yard and the outer court in dimensions. For example, 

 in a building 150 feet high, an inner court at the top could be 25 feet square 

 or a little less than 18 by 36 feet ; at 90 feet in height at the top it would 

 have to be 15 feet square or contain 225 square feet, provided that it were 

 not more than twice as long as it were wide for that area. In the case of 

 a building which was not back to back with another building, an outer court 

 could use the minimum provisions here stated for outer courts only in case 

 the rear yard on which it opened was of the dimensions here given for an 

 inner court; that is to sav, at 150 feet in height, 25 square feet or 18 by 

 36 feet, or with dimensions somewhere between, giving an area of 62? feet 

 (see Figure 152). However, a special exception is made to the above espe- 

 cially for corner buildings on narrow lots according to which the - oi 

 such an inner court may be reduced if connected with the street by a side 

 vard.
