The 14-unit, three-story apartment building at 3475 16th Street, owned by Romel Sfapt Llc, was constructed in 1912 and has undergone significant recent modifications, most notably the addition of two ADUs in the basement level completed in 2020. The building has been through substantial safety and infrastructure upgrades, including a new fire sprinkler system installation in 2019 with 28 heads, smoke detectors, and a comprehensive fire alarm system upgrade.

The property has completed its mandatory soft-story seismic retrofit under Tier 3 requirements. Recent maintenance and safety concerns include multiple instances of water supply issues during construction in 2020, temporary blocking of egress routes, and several 311 calls regarding building systems and external maintenance. The building has experienced periodic heating and hot water system problems, with complaints in 2019 and 2021 regarding these essential services.

While there have been several fire safety inspections and complaints between 2005-2021, most were determined to be without merit, though some did require corrections. The property has maintained active permits and completed various interior upgrades over the years, including plumbing and electrical improvements, bathroom renovations, and boiler system updates. Recent issues in 2024 included a sewage backup discharge from the side sewer vent, which was resolved through field work completion.
