The 35-story, 229-unit residential building at 511 Third Avenue in Murray Hill, owned by Michael Himy, was completed in 2021 and has undergone several notable incidents in its short history. Most concerning are recurring heat and hot water issues, with three documented complaints between late 2023 and 2025, including one affecting the entire building in November 2023 and a more recent apartment-specific complaint in March 2025, though inspectors found no violations in the latter case. The building has also experienced various maintenance challenges, including plumbing issues in September 2024 (which inspectors couldn't initially access), flooring problems in March 2024, and ventilation system concerns in December 2023, all of which were addressed according to HPD resolutions.
