Kensington sits in Brooklyn Community District 12, which Local Law 126 basement legalization does not cover, so a new ADU is the legal path to a second unit.

PropertyShark reports a Kensington median sale price of $675,000 for Q3 2026, up 8.1% year over year, from 40 sales, down 27.3%. Redfin reports $679,672 for the three months ending August 2026, up 21.1%, from 44 homes sold, down 48.4%, with a median of 57 days on market and 100.5% sale-to-list.

The two sources land within about $5,000 of each other on price but disagree on the growth rate, and Redfin's Kensington listings sit in ZIPs 11218, 11219 and 11230. Sales volume fell sharply in both, so a buyer should expect fewer homes to choose from.
NYC City Planning's guide says an accessory dwelling unit is 800 square feet or less and sits on the same lot as a one- or two-family home. Basement and detached ADUs are not allowed in the expanded flood area, which covers the 2050 and 2080 flood plains. Detached ADUs are not allowed in historic districts or in R1-2A, R2A and R3A zoning districts. Source: nyc.gov, City of Yes Housing Opportunity ADU guide.
The Department of Buildings began accepting ADU applications on September 30, 2025. City Planning's guide says homeowners must live at the property to build an ADU, while the DOB page does not state an owner-occupancy rule, so Joseph Ranola advises buyers to confirm that point with the filing architect or expediter.

No, not under Local Law 126 of 2024. The law covers Brooklyn Community Districts 4, 10, 11 and 17, Bronx districts 9, 10, 11 and 12, Manhattan districts 2, 3, 9, 10, 11 and 12 and Queens district 2. Kensington is in Brooklyn Community District 12, which is not on the list. Source: nyc.gov, Local Law 126 of 2024; Brooklyn Community Board 12.
The absence matters because many buyers assume any Brooklyn basement can be legalized. For Kensington, the realistic route to a legal second unit is a new ADU on a qualifying one- or two-family lot, and Joseph Ranola checks the lot's zoning district before discussing rental income.
PropertyShark counts 2,201 two-to-four family units among Kensington's 6,401 residential units, about 34%, alongside 786 single-family, 2,782 co-op and 618 condo units. PropertyShark groups two-to-four family together, so it does not show how many are one- or two-family lots that qualify for an ADU. Source: propertyshark.com, Kensington.
The ADU rule applies to one- and two-family homes, so Joseph Ranola counts the legal units on each lot before a buyer counts on ADU income. The 30-year fixed rate averaged 7.32% for the week of October 22, 2026, down from 7.40% the prior week, according to Freddie Mac.
Joseph Ranola confirms the legal unit count, checks the zoning district and flood status early and coordinates with the architect or expediter who files. Joseph Ranola serves every neighborhood across Staten Island and Brooklyn, from Tottenville to Williamsburg.
