AI summary · updated June 2026

258 West 123rd Street, a four-story, three-unit old-law tenement building in Harlem owned by Alejandro Vazquez, has experienced significant pest management challenges in recent years. The building, constructed in 1910, has been subject to recurring issues with bedbug reporting compliance, receiving annual violations from 2021 to 2024 for failure to file the required annual bedbug reports as per Housing Maintenance Code requirements. Most notably, there has been a persistent rodent problem, with the most recent inspection records from 2024 showing multiple instances of rat activity, followed by bait applications in February and March 2024, and a notable "rat sighting" complaint to the Department of Health and Mental Hygiene in August 2020 that resulted in documented violations.

Despite some recent positive developments, the rodent issue appears to remain a concern. The building passed rodent inspections in early 2025 (January and July) and had successful inspections in 2024 (April and July), suggesting potential improvement in pest management. However, the property continues to carry open violations related to bedbug reporting requirements as of 2024. Additional historical records from 2019 indicate a complaint regarding certificate of occupancy issues, though this was marked as "Inspector Unable To Gain Access" on two attempts. The building's documented history shows a pattern of pest-related challenges, with the most recent open violations focusing on bedbug reporting requirements and previous rodent activity.
