Zoning

R6B

Residence District - Contextual

R6B districts are often traditional row house districts, which preserve the scale and harmonious streetscape of neighborhoods of four-story attached buildings developed during the 19th century. Many of these houses are set back from the street with stoops and small front yards that are typical of Brooklyn's brownstone neighborhoods, such as Park Slope, Boerum Hill and Bedford Stuyvesant.
