Augrented Insights Report for 166 East 91st Street

The five-story, 20-unit Old Law Tenement building at 166 East 91st Street, owned by Walter Saindach, has experienced recurring maintenance challenges over the past several years, particularly regarding heat/hot water issues and pest management. Most recently, in April 2025, there were heat complaints that were investigated but found not to violate HPD housing laws. Prior to that, similar heat complaints were recorded in July 2024 and before that in 2020 with varying resolutions.

The building has documented multiple pest-related incidents between 2019 and 2021, with HPD inspections sometimes unable to gain access. Recent rodent inspections in 2023 and 2024 showed rat activity, though most recent inspections in 2025 passed. The building has also faced several infrastructure and safety-related issues, including door/window problems in 2021 (with multiple complaints), water leaks in 2019 (both heavy and slow), and various housing maintenance code violations.

Notable violations from 2022 include missing or defective window guards, self-closing doors, and carbon monoxide detectors in apartments 4B and 5N, though some of these were subsequently certified as corrected. The property has consistently filed bedbug reports showing zero infested units from 2023 to present, and recent rodent inspections from 2023 to 2025 have shown some improvement in conditions. Historical records from 2018-2020 show general work permits issued for plumbing and electrical work, and a building vibrational stability complaint from 2020 was investigated with no violations found.
