305 East 51st Street, Manhattan, NY 10022

305 East 51st Street, known as The Halcyon, is a 32-story, 123-unit residential condominium building located in Midtown Manhattan, completed in 2007 and currently owned by Daniel Hurwitz. The building has experienced several maintenance issues over the years, with the most recent concern being an unsanitary condition involving garbage/recycling storage reported in August 2024, though no violations were found.

There are two active ECB violations from 2024 regarding the parking structure's unsafe condition, both with $2,500 penalties, and additional violations related to failure to submit required reports regarding exterior walls and appurtenances. While the building has maintained a clean bedbug record with zero reported infestations or reinfestions since 2019, there have been multiple complaints about door/window issues and construction-related dust in 2020, along with a mouse sighting in 2019. The building's infrastructure has shown some recurring maintenance needs, particularly concerning the elevator system, with multiple violations and inspections between 2018-2024.

Notable events include a rat activity finding during a March 2024 inspection (though previous and subsequent inspections have passed), and various door/window-related complaints in 2020 that were either uninspected or resolved with no violations found. The property has consistently filed its required bedbug reports showing no infestations, and while there were concerns about construction lead dust and indoor air quality in early 2020, these issues appear to have been resolved. The building's management has generally responded to violations and complaints, with many being dismissed or resolved, though some remain active as of 2025, including a 2023 violation regarding the failure to file external low-pressure inspection documents.
