(f) Nothing in this article shall prevent the projection of a cornice 

 beyond the street wall to an extent not exceeding five per cent of the width 

 of the street nor more than five feet in any case. Nothing in this article 

 shall prevent the erection above the height limit of a parapet wall or cornice 

 solely for ornament and without windows extending above such height limit

 height limit. 



(g) The provisions of this article shall not apply to the erection of 

 church spires, belfries, chimneys, flues or gas holders. 



(h) Where not more than 50 feet of a street frontage would otherwise

 both ends of such frontage, the height limit on such frontage shall be equal 

 to the lesser of such greater height limits. 



(i) If an additional story or stories are added to a building existing at 

 the time of the passage of this resolution, the existing walls of which are in

Article IV — Area Districts 



§ 10. Area Districts. For the purpose of regulating and determining 

 the area of yards, courts and other open spaces for buildings hereafter 

 erected, the City of New York is hereby divided into five classes of area 

 districts : A, B, C, D and E ; as shown on the area district map which accom- 

 panies this resolution and is hereby declared to be part hereof. The area 

 districts designated on said map are hereby established. The area district 

 map designations and map designation rules which accompany said area 

 district map are hereby declared to be a part thereof. No building or part 

 of a building shall be erected except in conformity with the regulations 

 herein prescribed for the area district in which such building is located. 

 Unless otherwise expressly provided the term rear yard, side yard, outer 

 court or inner court when used in this article shall be deemed to refer only 

 to a rear yard, side yard, outer court or inner court required by this article. 

 No lot area shall be so reduced or diminished that the yards, courts or open 

 spaces shall be smaller than prescribed in this article. 



§ 11. A Districts. In an A district a court at any given height shall 

 be at least one inch in least dimension for each one foot of such height. 



§ 12. B Districts. In a B district a rear yard at any given height shall 

 be at least two inches in least dimension for each one foot of such height. 

 The depth of a rear yard at its lowest level shall be at least 10 per cent, of 

 the depth of the lot, but need not exceed 10 feet at such level. An outer 

 court or a side yard at any given height shall be at least one inch in least 

 dimension for each one foot of such height. An outer court at any given 

 point shall be at least one and one-half inches in least dimension for each 

 one foot of length. But for each foot that an outer court at any given 

 height would, under the above rules, be wider in its least dimension for such 

 height than the minimum required by its length, one inch shall be deducted 

 from the required least dimension for such height for each 24 feet of such 

 height. A side yard for its length within 50 feet of the street may for the 

 purposes of the above rule be considered an outer court.
