Summary · as of November 10, 2026

9517 Flatlands Avenue (Brooklyn, NY 11236; tax lot BBL 3081830007) is a one-family home (building class A1: one-family home, two stories, detached), built around 1930, on a 1,873 sq ft lot zoned R4-1. City tax records list the owner as DIAMOND, JUDITH; per ACRIS, a deed to this owner dated January 31, 2020 lists a price of $632,000. The Department of Finance's final market value for tax year 2027 is $814,000. As of November 10, 2026, NYC Open Data shows no open DOB jobs, no active DOB, DOB NOW safety or ECB violations and no open HPD violations for this lot, but it does show one OATH ticket with an unpaid balance. An unpaid OATH ticket is a fine the city says is still owed. It is counted separately from violations, so this lot has no open violations but is not free of outstanding items.
