The property at 637-639 Central Avenue is a two-unit, two-story multi-family residential building located in the Park North neighborhood, constructed in 1904 and currently owned by the E & J Mironov Family Trust. The building has undergone significant renovations and improvements over the years, with the most substantial work completed in 2009-2011, including the excavation of the first floor for a new two-car garage, living space expansion, and comprehensive updates to both units' kitchen and bathroom facilities at a total cost of approximately $145,500.

Structural improvements were made in 2007 with dry rot repairs to the rear stairs and foundation reinforcement, while essential systems upgrades occurred between 2008-2013, including electrical system modernization, plumbing renovations, and the installation of new HVAC equipment. Recent activity at the property has been relatively limited to maintenance and external improvements, such as the installation of a standing window sign for a driving school in 2022.

The building's maintenance history shows regular upkeep, including reroofing work completed in 2011. The surrounding area has experienced typical urban challenges, with multiple 311 calls recorded between 2021-2024 primarily relating to street cleaning and garbage issues, though these are external to the building itself. A notable incident of graffiti was reported in April 2022 and remains open as of October 2023.
