471-473 21st Ave, San Francisco, CA 94121

The 4-unit multi-family residential building at 471-473 21st Avenue in the Central Richmond neighborhood is a 2-story structure built in 1916, currently owned by Trac Renee. The building has undergone several significant maintenance and improvement projects over the years, including a complete sewer and water main replacement in 2010, reroofing work in 2000, and substantial interior renovations in 1999 that involved remodeling kitchens and bathrooms, as well as switching kitchen and storage areas.

A notable cluster of fire safety violations was recorded in October 2002, with issues related to combustible storage, smoke detectors, egress obstruction, fire proofing, and fire extinguisher maintenance, though all these violations were abated by January 2003. More recent history shows regular building maintenance and some urban challenges typical of the area, including multiple parking enforcement calls and reports of debris.

The most recent 311 call was in August 2024 regarding abandoned electronics, and there have been several parking-related incidents in the vicinity between 2019 and 2023. An active plumbing complaint remains on record from January 1999 regarding unauthorized electrical and plumbing work, though this is now quite dated given the intervening years and subsequent improvements to the building's systems. The building's maintenance history suggests regular upkeep, with permissible improvements including street space and sidewalk maintenance in 2010.
