DISTRICTING RESOLUTION ANNOTATIONS 



257 



Sec. 1, Par. (k). The definitions of courts are approximately the 

 same as those of the Tenement House Law. In the case of a building that 

 is not required to have a rear yard, a rear open space equal in size to an 

 inner court is required where 'an outer court or a side yard opens on it. 



Sec. 1, Par. (1). The height of yards and courts will as a general rule 

 be measured as they are in the Light and Ventilation Article of the Build- 

 ing Code, that is, from the lowest level of the yard or court. In a business 

 district the lowest level might be the top of the ground story or it might 

 be 23 feet above the curb. To allow for stairway and elevator pent houses, 

 the highest level of a court or yard wall can be the mean of all of the 

 highest levels of such wall. As an exception to the above rule for all build- 

 ings that are subject to the provisions of the Tenement House Law, the 

 height of yards and courts will be measured from the curb level even though 

 the yard or court actually starts at or above the second floor level. 



Sec. 1, Par. (m). If a court or yard is of irregular shape, say, for 

 example, a trapezoid, the mean clear horizontal dimensions in each direc- 

 tion will be calculated and the least of these would be the one taken for the

purposes of this resolution. The exact method of computing such dimen- 

 sions will presumably be covered by a rule of the Board of Standards and 

 Appeals. 



Sec. 1, Par. (n). The length of an outer court should always be 

 measured from the closed end. This is done with a view to encouraging 

 the widening of courts near the open ends. 



Sec. 8, Par. (b). Exactly the same principles apply in all five dis- 

 tricts. The accompanying diagram shows the five curves of limiting heights. 

 In a one and one-half times district the height of all buildings will be made 

 to conform approximately to that now provided for in the Tenement House 

 Law. However, on account of the difference in definition of curb level, 

 buildings other than tenement houses will take their height from the widest 

 street and not from the street of greatest grade. A setback means briefly 

 this : that if an owner wishes to carry a building to a greater height than 

 that allowed on the street line, as, for example, above 90 feet on a 60-foot
