143 Avenue B, Manhattan, NY 10009
143 Avenue B is a 16-story, 83-unit commercial altered Class A building constructed in 1928 and currently owned by Nick Kalaj. The building has experienced several concerning maintenance issues in recent years, with the most significant being a partial vacate order issued in June 2025 due to safety concerns involving bulging masonry, spalling brick/mortar, and step cracking observed at the neighboring building (605 E 9th Street). This structural issue led to the restriction of access to vacated areas and the evacuation of all terraces.
The building has also faced repeated heating system challenges, with a heat/hot water complaint recorded in October 2024 that resulted in HPD's inability to access units for inspection. The property's maintenance history reveals several pattern violations, particularly relating to failure to file required inspections, though these violations were subsequently dismissed. These include multiple instances of not filing External Low Pressure Inspection reports from 2018 through 2021, as well as a boiler inspection violation from 2017.
Despite these violations, the building has maintained a clean record regarding pest control, with zero documented cases of bedbugs between 2019-2025 and consistent passing results on rodent inspections from 2022 through 2025. Recent inspections have shown active compliance with rodent control measures, though a single failed inspection in April 2023 for "Other Reasons" was noted. The building has undergone regular maintenance work as evidenced by multiple permits issued for plumbing and other repairs between 2018 and 2022, including three plumbing-related permits issued in 2022 alone.
