1258-1260 21st Ave, San Francisco, CA 94122

The property at 1258-1260 21st Avenue in the Central Sunset neighborhood is a two-story multi-family residential building constructed in 1921, currently containing 3 units and owned by Mei C & George Hsu. The building underwent a significant vertical and horizontal extension in 1987, which was completed properly.

However, in March 2012, serious concerns were raised when multiple complaints were filed regarding potential illegal units within the building, particularly in the basement area of unit 1258 which allegedly housed approximately 19 residents. These complaints, filed with both Housing Inspection Services and the Plumbing Inspection Division, reported unauthorized construction work including kitchen and bathroom renovations, installation of separate units without proper fire escapes, and other work beyond the scope of existing permits. While the building had one plumbing issue addressed in 2012 involving the replacement of a kitchen P-trap, the more critical concerns from March 2012 were notably marked as "Not Active" following inspections.

The property has had several parking-related incidents in recent years, with multiple citations issued between 2016 and 2022 for driveway blockages involving various vehicles, primarily a red Honda Odyssey. A utility excavation issue was reported and resolved in April 2016, which was related to San Francisco Public Utilities Commission work requiring temporary restoration. While the building's historical extension and 2012 plumbing repairs suggest some level of maintenance, the 2012 complaints regarding unauthorized units and safety concerns represent the most significant and potentially impactful issues on record for this property, despite their subsequent inactive status.
