NYC Zoning Handbook:
Residential Districts: R9X

The regulations of R9X districts are similar to those of R9A districts except for minor variations in street wall height, sky exposure planes and a higher allowable residential density. They typically encourage 15-story residential buildings with high lot coverage. This district is currently mapped in Manhattan on Lexington Avenue on the Upper East Side and in the Murray Hill area.

The FAR in R9X districts is 9.0. On wide streets, the first two stories of the front wall of a new building must abut the street line and occupy the full width of the lot On narrow streets, the front wall of a new building must not be farther from the street than the front wall of an adjacent building. The maximum building height and setbacks are determined by the building envelope which may not be penetrated by the building. The building envelope is controlled by the intersection of front and rear sky exposure planes that rise according to a specific ratio. The Quality Housing Program is mandatory in R9X districts.
