R4A Zoning Code - New York City


What is an R4A Zoning District?

R4A districts permit only one- and two-family detached residences. Differences in the permitted floor area ratio and minimum required lot size, however, result in differences in the typical buildings found in each district. Characterized by houses with two stories and an attic beneath a pitched roof, R4A districts have a FAR of up to 0.75 (plus an attic allowance) and a minimum lot width of 30 feet. The districts are usually mapped in older neighborhoods.

As in R3A and R3X districts, the perimeter wall of a house may ride to 21 feet before sloping or being set back to the maximum building height of 35 feet. The amount of required open space in R4A districts is governed by yard requirements: a front yard at least 10 feet deep and at least as deep as an adjacent front yard up to a depth of 20 feet; a 30-foot-deep rear yard; and two side yards that total at least 10 feet and a minimum width of at least two feet each.

One off-street parking space is required for each dwelling unit. Parking must be located in a driveway along a side lot ribbon if the lot is less than 35 feet wide. If the lot if 35 feet or wider, a garage is permitted within the house, provided the driveway is at least 18 feet deep.
