Todt Hill recorded only 6 home sales in Q3 2026, down from 18 a year earlier, so an ADU decision here rests on lot facts and not on a market trend.

Joseph Ranola is a real estate broker and not an architect or expediter. An architect or expediter files the Department of Buildings application for an accessory dwelling unit, and this page covers the brokerage side: what a Todt Hill home is worth with or without one and how to market it.
PropertyShark reports a Todt Hill median sale price of $1,050,000 for Q3 2026, up 3.4% year over year, from just 6 recorded sales, down from 18 in Q3 2025, at $537 per square foot. Redfin, measuring the three months ending August 2026, reports a higher $1,284,380 from 8 sales, and both figures rest on samples too small to call a trend. Joseph Ranola prices a Todt Hill home from the specific block and house, not from either median.
PropertyShark’s housing-stock table counts 2,312 single-family homes, 280 two-to-four family buildings and 237 condo units among 2,833 residential units in Todt Hill. Single-family houses are about 82% of the stock, which is why the ADU question matters here more than in a condo-heavy neighborhood.
Generally yes, if the lot qualifies. The NYC Department of Buildings states that an accessory dwelling unit is capped at 800 square feet of zoning floor area, that the zoning lot must be the primary residence of an owner when the unit is first occupied, and that a one- or two-family home may add one ADU. Since City of Yes for Housing Opportunity took effect in December 2024, those rules apply citywide, and DOB NOW began accepting ADU filings on September 30, 2025.
The same DOB pages bar basement or cellar ADUs in high-risk flood areas and bar backyard ADUs in flood-risk areas and historic districts. A two-family house that adds an ADU is treated as a three-family building under state law unless a fire wall separates the unit. Source: nyc.gov/site/buildings/codes/adu.page.
For nearly every Todt Hill lot, flood risk is not the constraint. PropertyShark’s risk table lists 4 flood-zone buildings and zero hurricane-evacuation-zone buildings out of 2,600 Todt Hill residential buildings, which is about 0.15%. That compares with 67% of Sheepshead Bay’s buildings in a hurricane evacuation zone, a gap Joseph Ranola can show any buyer comparing the two boroughs.
A building-count table is not a zoning finding for your lot. This page has not verified whether the Special Natural Area District or any hillside rule changes what a particular Todt Hill lot may build, so an architect should confirm that before a plan is drawn. Joseph Ranola does not give that opinion.
An ADU adds value only when it is legal, permitted and rentable, and Joseph Ranola advises owners to treat an unpermitted unit as a liability that surfaces in the buyer’s due diligence. A permitted unit can support a buyer who wants rental income. Because the owner-occupancy requirement applies when the unit is first occupied, buyers and lenders will ask for the certificate of occupancy and the filing history before they pay for the extra income.
The Department of Buildings also runs a pilot legalization path for units that existed before April 20, 2024, with applications due by April 20, 2029. An owner of an older Todt Hill house with an existing apartment should speak to an architect about that window before listing.
Joseph Ranola explains what a Todt Hill house sells for today, what a legal ADU could change, and who must be hired to file it, without overstating either. Joseph Ranola serves every neighborhood across Staten Island and Brooklyn, from Tottenville to Williamsburg.
