NYC Zoning Handbook:
Residential Districts: R1
A few areas of the city, such as sections of Douglaston in
Queens, Riverdale in the Bronx, and Midwood in Brooklyn, are
mapped as R1 districts to conform with existing development.
R1 districts permit only single-family detached houses on
lots at least 100 feet wide (in R1-1 zones) or 60 feet wide
(in R1-2 zones). These zones limit population density by
allowing only four to seven families per acre. Usually, the
houses are on large landscaped lots. Many of these areas are
far from public transportation. Most families in these
districts own at least one car. One parking space is required
for each dwelling unit.
