510 East 88th Street, Manhattan, NY 10128

510 East 88th Street is a 5-story, 20-unit Old Law Tenement building constructed in 1910 in New York City's Upper East Side neighborhood, currently owned by John McCarthy. The building has experienced recurring issues with heat and hot water, particularly evident in emergency complaints filed in 2025 (May and April) and multiple instances in late 2023 (November), with several complaints resolving through tenant contact verification of corrections.

more concerning, there is an active C-Class housing violation for cockroach infestation in apartment 3D as of October 2023, and multiple rodent-related incidents have been documented, with the most recent inspection in July 2025 passing but previous reports indicating rat activity and bait application from September 2023 through February 2024. The building's maintenance history shows attention to various issues, including a gas supply problem in apartment 1D (June 2023), and several paint/plaster concerns documented in late 2022. While the property has consistently filed bedbug reports from 2021 through 2024 showing zero infested units each year, there have been multiple rodent inspections and bait treatments applied throughout 2023-2024.

The Department of Health and Mental Hygiene has conducted inspections in response to complaints, most recently in June 2025 regarding rodent signs, which resulted in no violations. An earlier emergency complaint about unsanitary conditions/pests was filed in March 2023, and there was one complaint about excessive debris in June 2022 which was dismissed upon inspection. The building appears to require ongoing monitoring for both pest management and heating system reliability, based on the frequency and nature of reported issues.
