# 305 3rd Avenue, Park Slope, Brooklyn, NY 11215 BBL 3004540005 · Block 454 · Lot 5 · BIN 3007687 Canonical page: https://nycpropertyfacts.com/ny/brooklyn/305-3rd-avenue-3004540005 Last updated: 2026-11-09 · Open-item counts as of 2026-11-10 ## Summary 305 3rd Avenue (Brooklyn, NY 11215; tax lot BBL 3004540005) is a school or educational building (building class W1: educational building (subtype W1)), built around 1966, on a 8,592 sq ft lot zoned M1-4/R6B. City tax records list the owner as WSEM REALTY LLC. The Department of Finance's final market value for tax year 2027 is $1,035,000. 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. There were 31 311 requests in the past 12 months and no HPD complaints since 2019. (Source: NYC Open Data — DOB, HPD, OATH, DOF, DCP and ACRIS datasets — compiled by NYC Property Facts.)
