519 West 139th Street, Manhattan, NY 10031

The 25-unit, 5-story apartment building at 519 West 139th Street in Hamilton Heights, owned by G.t.t.g Enterprises Corp., has experienced persistent heating and hot water system issues over the past few years. The most recent complaints in January 2025 and several previous incidents from 2023, 2022, and 2021 indicate recurring problems with the building's heat and hot water systems, though many of these complaints were eventually closed with reports of restoration.

The building has also faced challenges with rodent control, as evidenced by multiple failed inspections in 2024-2023 showing rat activity, though there were some passed inspections as well. Notably, there are two active Environmental Control Board violations related to boiler issues from 2020-2021, with one violation carrying a penalty of $6,250 due to failure to comply with a Commissioner's order. In addition to these ongoing maintenance concerns, the building has a documented history of various housing violations from 2019-2022.

These include issues in Apartment 2A such as water leaks, mold conditions, and problems with a carbon monoxide detector in 2019, as well as violations related to the second-story public hall walls in 2022 requiring repairs and repainting. The building's bedbug reports from 2019-2025 suggest relatively low infestation rates, with only two infested units reported in 2019 and none in subsequent years. While the building is over a century old (built in 1910), it has undergone regular inspections and has had its violations closed out, indicating some level of compliance with housing maintenance codes despite the ongoing heating and rodent issues.
