The building has also received substantial interior upgrades, with multiple units (1, 2, 3, 6, 10, and 12) undergoing bathroom and kitchen renovations in 2019, including new vanities, tubs, toilets, electrical upgrades, and cabinet replacements. The building's maintenance history reveals a series of fire safety upgrades, including multiple fire alarm system replacements between 2018-2020 to comply with current codes, though some related violations were noted in 2019. Significant building challenges were documented in 2019, including multiple housing code violations regarding water damage, plumbing issues, and interior surface problems, all of which were abated by October 2022. The property has experienced recurring issues with the fire alarm system, with multiple complaints and violations recorded between 2013-2023, though most were promptly corrected.

Recent building complaints have included concerns about weather stripping (2022) and plumbing leaks (2019), with the latter resulting in visible damage between units. The building's permit history shows regular maintenance and upgrades, including reroofing work in 2022 and various unit-specific improvements. While the majority of historical violations have been resolved, there is a recurring theme of fire safety system maintenance and prompt response to resident concerns. Recent improvements suggest ongoing investment in the property's infrastructure, though some maintenance issues have required multiple interventions before resolution.
