R4-1 Zoning Code - New York City
What is an R4-1 Zoning District?
R4-1 districts permit only one- and two-family detached and semi-detached residences. Despite a narrower lot requirement of 25 feet for detached homes, houses on R4-1 districts tend to be larger than those in R3-1 districts because of the higher floor area ratio of 0.75 plus an attic allowance. The perimeter wall may rise to 25 feet, compared to 21 feet in R3-1 districts, before sloping on being set back to a maximum building height of 35 feet.
The amount of required open space on R4-1 zoning lots is governed by yard requirements. Two side yards that total eight feet must be provided for a detached residence. Although there is no minimum width for each side yard, there must always be eight feet between buildings on adjacent zoning lots. One four-foot side yard is required for each semi-detached residence, which must be on a lot at least 18 feet wide.
Zero lot lined residences are permitted in R4-1 districts, and require only one eight-foot side yard. Front yards must be at least 10 feet deep and at least as deep as an adjacent front yard, up to a depth of 20 feet. One off-street parking space is required for each dwelling unit. Parking must be within the side or rear yard or in a garage.
