The three-unit residential building at 3186-3188 16th Street, owned by Tan Shu Hua and located in Mission Dolores, is a three-story flats structure built in 1907.

In 2023, the building underwent drywall and insulation replacement, and earlier improvements included kitchen and bathroom renovations, window replacements, and electrical service upgrades to 200A in 2021. The building has experienced several maintenance and compliance issues over the years, most notably a series of violations in 2017 related to water damage, rodent infestation, and interior surface repairs, which were abated by May 2017. There are currently three active complaints from 2020-2023 regarding unauthorized renovations, including new bathrooms, windows, and recessed lighting, as well as concerns about illegal window openings causing noise issues.

The building's mechanical systems have been updated regularly, with furnace replacements in 2011 and 2024, though there was a significant complaint about lack of heat for four years in 2011 that was eventually resolved. Recent activity in late 2024 shows multiple reports of garbage and debris issues near the property, while earlier records indicate various fire safety concerns between 2006 and 2022, though most were promptly addressed or corrected. The building has maintained its general structure and systems through regular upgrades and repairs, with documented compliance efforts to address past violations.
