The two-unit residential building at 170 Caselli Avenue, owned by Melling Torr W & Candelario, was constructed in 1951 and has undergone several significant infrastructure improvements in recent years. Most notably, the property is currently undergoing major electrical upgrades, with a new 400-amp main service installation and two-meter panel configuration expected to be completed by late 2024.

The building has seen substantial energy efficiency improvements, including double-pane window replacements in 2021 and two separate furnace upgrades in 2021 and 2024, indicating ongoing commitment to modernization. The property's structural maintenance history shows attention to basic upkeep, with multiple roof replacements recorded between 1989-2008, and repair work to address dry rot issues in 1986. The building's maintenance record demonstrates regular upkeep, though the property has experienced some infrastructure challenges over the years, including an expired roofing permit from 1989 and dry rot issues requiring stair repairs in 1986.

The surrounding area has been active in terms of community reporting, with multiple 311 calls primarily related to parking issues and street maintenance, though these are not directly related to the building's condition.
