The property at 416-418 Frederick Street is a two-unit, two-story multi-family residential building constructed in 1900, currently owned by the Joseph Szlamnik Jr Trust. The building has undergone several significant renovations over the past 25 years, with the most recent work in late 2023 focused on HVAC improvements, including the replacement of five supply ducts and a rooftop gas package unit with associated electrical work completed in early 2024.

Major conversions of the ground floor have been completed, transforming parking and storage areas into additional dwelling space, including a $28,000 project in 2001 that created two bedrooms, kitchen, and bathroom facilities. The building has also received attention to maintenance issues, with a sewer replacement completed in 2017 and earlier repairs addressing dry rot on stairs in 1998. Recent inspections and permits indicate regular maintenance and upgrades, though the property has experienced some external issues as documented in 311 calls, primarily related to street cleaning and illegal postings between 2015 and 2024.

The building's modifications and improvements have been carefully documented through various permits, with most recent works focusing on modernizing HVAC systems and plumbing infrastructure. Planning records show the successful conversion of ground floor spaces to living areas, with necessary variances obtained for open space and exposure requirements. The property has maintained a solid record of responding to maintenance needs, with no recorded fire incidents or civilian injuries associated with the building.
