PropertyShark reports a Randall Manor median sale price of $870,000 for Q3 2026, up 42.6% year over year, on nine sales, down 40%. Median price per square foot was $479, up 24.3%. Nine sales is a thin sample, so the 42.6% move is a snapshot and not a trend. An owner weighing an ADU should price the specific house against recent comparable sales.
New York City zoning allows one ancillary dwelling unit per one- or two-family home, capped at 800 square feet, as amended by City of Yes for Housing Opportunity on December 5, 2024. The lot must be the owner’s primary residence when the ADU is first occupied. No ADU is allowed below the flood-resistant construction elevation in a high-risk flood zone, and basement or cellar ADUs are barred inside the 2050 rainfall flood risk area. An architect or expediter confirms whether a specific lot qualifies.
PropertyShark counts 56 of 1,668 Randall Manor residential buildings in a flood zone and 154 in a hurricane evacuation zone. Single-family homes account for 24 of the flood-zone buildings and two-to-four family buildings for 32. A buyer or owner planning a basement unit should check the flood status of the exact address first.
PropertyShark lists 1,162 single-family units, 498 two-to-four family units, 46 condos, 8 co-ops and 1 townhouse, out of 1,715 residential units. Two-to-four family units are about 29% of the stock, based on those counts. That mix means a rental-income buyer can choose between a legal multi-family house and a single-family home with ADU potential.
Joseph Ranola prices income-producing and ADU-capable houses with the zoning and flood facts on the table instead of guessing. Joseph Ranola serves every neighborhood across Staten Island and Brooklyn, from Tottenville to Williamsburg.
