529 Underhill Avenue, Bronx, NY 10473

529 Underhill Avenue, a 4-unit, 2-story residential building in Clason Point owned by Sam Klein, has faced numerous maintenance and safety challenges in recent years. Most concerning are the pattern of inspections that HPD has been unable to complete since 2025, including attempts to investigate complaints about water supply issues, heat and hot water problems, and plumbing concerns. The building has experienced recurring heat and hot water issues, with multiple complaints filed in 2025 alone, along with ongoing plumbing problems and unsanitary conditions involving garbage storage.

In February 2023, Apartment 3 was found to have multiple safety violations, including defective smoke and carbon monoxide detectors, and an insect infestation that required official abatement. The building's maintenance history reveals additional serious concerns, including open violations from 2023 related to the vestibule's fire retardant materials, and multiple active ECB violations as of 2023 regarding combustible debris, unsanitary waste, and masonry issues. Four complaints about illegal commercial use in the residential zone have been filed between 2024 and 2025, though inspectors were unable to gain access during their attempts.

The property has also faced challenges with rodent control, with failed inspections noted in 2021 and 2024, despite an active bedbug reporting record showing no infestations from 2022-2025. Multiple Department of Buildings violations and complaints about illegal conversions and locked egress points have been recorded, though many inspections were hindered by restricted access. A notable pattern is the building's failure to maintain basic infrastructure, requiring numerous emergency responses from HPD for heating, plumbing, and door-related issues between 2025 and 2024.
