The 7-unit, 3-story apartment building at 3483-3485 21st Street in the Eureka Valley/Dolores Heights neighborhood was constructed in 1922 and is currently owned by 3485 21st Street LLC. The property has undergone several significant improvements over the years, most notably completing its mandatory soft-story seismic retrofit in 2022 (though with some related complaints about unfinished work in 2015). Recent building maintenance has included multiple unit renovations, with records showing kitchen and bathroom remodels in Units 1, 5, and 6 between 2014-2019, along with electrical upgrades including new lighting and fixtures.

The building experienced a repeat issue with its boiler permits from 2010 through 2024, with the most recent complaint filed in June 2024 regarding an expired permit. Between 2020-2024, the building has faced several challenges with rodent infestations, as evidenced by multiple health department calls, with the most recent incidents recorded in 2024. The property's maintenance record shows regular updates to essential systems, including a steam boiler replacement in 2017, hot water tank replacement in 2022, and sewer lateral repairs in 2016.

Historical violations from 2007-2008 included various building maintenance issues such as lead paint concerns, damaged walls, and weatherproofing problems, though these were marked as resolved. The building's plumbing and electrical systems have received attention through multiple permits showing upgrades to fixtures, including the replacement of all unit toilets with low-flow models in 2012. Recent 311 calls have primarily concerned pest control issues, with multiple reports between 2020-2024 noting rodent infestations that were referred to health authorities. The property currently maintains its active residential multi-family status and shows compliance with major safety requirements such as the completed soft-story retrofit program.
