18 West 123rd Street, Manhattan, NY 10027

The three-unit, three-story building at 18 West 123rd Street in Harlem, owned by Jason Markham and dating back to 1882, has experienced several notable maintenance and safety issues over recent years. Most concerning are the building's recurring rodent problems, with multiple inspections between 2022 and 2025 showing rat activity, though recent inspections in 2024-2025 have passed.

The property has documented water drainage issues from 2018, when approximately 10 feet of rain leader downspout was missing from the roof gutter, leading to both Department of Buildings complaints and Environmental Control Board violations. There have also been violations related to bedbug reporting requirements, with the most recent citation in March 2023 regarding the failure to file an annual bedbug report, though subsequent filings show no current infestations. The building has demonstrated some compliance with pest management, as evidenced by multiple "Passed" rodent inspections in recent months.

The property's documentation shows a pattern of infrastructure maintenance challenges, including two dismissed violations in June 2023 for failure to file 2018 and 2019 external low pressure inspections, and an earlier water drainage violation from late 2018. While the building's bedbug reporting has shown no infestations since 2019, the property experienced its first documented infestation in late 2019 before establishing a pattern of eradication in subsequent years. The most recent rodent inspection results from 2024-2025 show improvement in pest control measures, representing the most consistent period of passed inspections in recent history.
