121 Post Avenue, Manhattan, NY 10034

121 Post Avenue is a 5-story, 10-unit residential building in Inwood, built in 1911 and currently owned by Ludovik Benedek. The building has experienced numerous maintenance issues over the past 18 months, with particular concerns around building systems and unit-specific problems. Most significantly, there are currently open violations in Apartment 9 from December 2024 regarding missing carbon monoxide detectors, defective bathroom caulking, unsecured steam radiator, and missing smoke detector. In Apartment 6, violations from December 2023 involve peeling paint requiring remediation under lead paint regulations, along with other maintenance issues.

The building has had recurring heat and hot water complaints throughout 2023-2024, both for individual units and building-wide systems, though some were resolved upon HPD verification. There have also been multiple complaints and violations regarding the intercom system and door-related issues. A concerning pattern of unsanitary conditions is evident, with multiple emergency and non-emergency complaints filed in 2025 regarding mold, pests, and plumbing issues. The building's maintenance record shows some positive trends, including consistent rodent inspection pass rates in 2025 and recent rodent control compliance inspections.

Bedbug reports have shown no infestations since 2019. However, there are active violations as of April 2023 regarding an unfiled low-pressure inspection, and previous heat, hot water, and intercom issues suggest ongoing building system challenges. While some complaints have been addressed and closed, many violations remain open, particularly concerning life safety systems (smoke/carbon monoxide detectors) and general maintenance issues affecting unit habitability. The building's age and history as a New Law Tenement is evident in the various maintenance challenges, though recent inspections indicate some improvements in pest control and building maintenance protocols.
