R4B Zoning Code - New York City
What is an R4B Zoning District?
Primarily a low-rise row house district limited to one- and two-family residences, R4B districts also permit detached and semi-detached buildings. However, the floor area ratio of 0.9 and building height limit of 24 feet typically produce a two-story, flat-roofed row house.
To maintain the characteristic row house streetscape of R4B districts, the front yard of a new house must be at least five feet deep and at least as deep as one adjacent front yard, but no deeper than the other, to a maximum depth of 20 feet. Detached houses must have two side yards totaling at least eight feet; there is no minimum width for a side yard but there must be at least eight feet between buildings on adjacent zoning lots.
Zero lot line buildings require only one eight-foot side yard and semi-detached buildings require one at least four feet wide. One off-street parking space is required for each dwelling unit, except that parking is waived for single-family houses and curb cuts are prohibited on zoning lots less than 40-feet wide. Front yard parking is prohibited.
