The three-story, seven-unit multi-family residential building at 24 Gerke Alley, also known as 477-481 Greenwich, was constructed in 1907 and is currently owned by the Joycelyn Anne Ong Trust. The property has undergone several significant improvements over the past decade, with the most recent work completed in October 2024 involving bathroom and lighting upgrades at a cost of $20,552. Notably, the building underwent a substantial soft-story retrofit in 2016-2017, including wall strengthening and foundation replacement work valued at $50,000, followed by a $500 fee for failure to submit required documentation.

Major system upgrades were completed in 2010, including a 400-amp electrical service upgrade and the installation of a hydraulic heating system with radiators for multiple units. The building has a documented history of maintenance issues in the mid-2000s, including heating system failures, interior surface problems, and fire safety concerns, all of which were addressed by October 2010. Several plumbing-related improvements were made between 2010 and 2013, including comprehensive fixture replacements, sewer line updates, and water line extensions.

The property has experienced multiple carbon monoxide detector activations in the past, though none resulted in injuries or indicated actual CO presence. Recent 311 calls from 2022-2024 primarily relate to street cleaning and parking enforcement issues outside the building, with only one concerning a sewage backup in 2022 that was promptly addressed. The most recent building-wide maintenance action was the bathroom finishes and plumbing fixture replacement completed in October 2024, suggesting ongoing investment in property upkeep.
