491-493 Vienna St, San Francisco, CA 94112

The two-unit, 2-story multi-family residential building at 491-493 Vienna Street in San Francisco's Excelsior neighborhood was built in 1895 and is currently owned by Yu-hwa Pa. The property's most significant recent history involves failed attempts at major construction projects, including a cancelled 2013 permit application for a substantial rear expansion that would have added height and new construction elements.

In December 2015, the building faced multiple housing code violations related to lead paint hazards, specifically concerning peeling and flaking paint on both interior and exterior surfaces, which were officially abated by February 2016. The property also experienced several concerning incidents in 2017, with complaints about unauthorized construction work and plumbing work being performed without proper permits. Older records show various building maintenance and compliance issues, including a completed 2011 permit for demolishing an unauthorized shed to comply with a notice of violation, and completed repairs from 1996 addressing exterior stucco walls and window replacements.

The property has had some recent activity related to street maintenance, with multiple 311 calls in late 2024 regarding overflowing city garbage cans and other debris on the street, though these are not directly related to the building's condition or management. There was also a complaint about graffiti on the sidewalk in front of the property in December 2024, which was transferred to SFUSD for handling. The only recorded fire-related incident was a false alarm.
