New Dorp has 1,525 single-family homes and 663 two-to-four family homes, and only one building in a flood zone. That matters for ADU plans.

PropertyShark’s housing-stock table for New Dorp lists 1,525 single-family homes, 663 two-to-four family homes, 102 condo units and 1 co-op, for 2,291 residential units. A neighborhood that is two-thirds single-family homes on their own lots is exactly where owners ask about a basement, attached or backyard accessory unit.
PropertyShark reports a New Dorp median sale price of $860,000 for Q2 2026, up 9.9% year over year, but on only 7 sales, down 61.1%. Redfin reports $704,160 for the three months ending August 2026, down 5.8%, on 14 homes sold, with a median of 38 days on market and a sale-to-list ratio of 102.8%.
Those two numbers point in opposite directions, and both rest on small samples. Joseph Ranola does not treat either as the price of a New Dorp house. An owner weighing an ADU should price the main house off individual recent sales of the same style and lot, and treat the median as background.
New York City allows an accessory dwelling unit of no more than 800 square feet of zoning floor area on a lot with a one- or two-family home, and the lot must be the primary residence of an owner when the unit is first occupied. These are the rules published by the NYC Department of Buildings and the Department of City Planning under City of Yes for Housing Opportunity.
Joseph Ranola is a real estate broker, not an architect or a DOB expediter. Whether a specific New Dorp lot qualifies depends on its zoning district, yards and existing certificate of occupancy, and an architect or expediter should confirm that before any offer or plan depends on an ADU.
Rarely, based on PropertyShark’s building counts. PropertyShark lists 1 of New Dorp’s 2,196 buildings in a flood zone and 17 in a hurricane evacuation zone, 8 of them single-family. The Department of Buildings states that subgrade ADUs are not permitted in high-risk flood areas, and City Planning states that basement and detached ADUs are not allowed in the expanded 2050 and 2080 flood areas.
The PropertyShark counts are not an official eligibility determination. They do show that, compared with shoreline neighborhoods, flood restrictions are unlikely to be the first obstacle in New Dorp.
Not right now. The HPD Plus One ADU Program page states that, as of June 12, 2026, intake for the program is closed. Joseph Ranola checks that page before telling any owner that financing help exists.
