171-173 Buena Vista Ave, San Francisco, CA 94117

The three-story multi-family residential building at 171-173 Buena Vista Avenue, owned by the Lois Anne Goodwill Trust, was constructed in 1904 and contains two units. The property has undergone several significant improvements over the past two decades, with the most notable recent works occurring between November 2024 and January 2025, including two consecutive sewage backup incidents from the side sewer vent that were promptly addressed by PUC - Sewer Operations.

The building's maintenance history shows attention to essential infrastructure, with structural upgrades including foundation bolting completed in 1995, termite and dry rot repairs in 1998, and a bathroom remodel in Unit 173 in 2009 that included comprehensive updates to plumbing, electrical systems, and fixtures. In addition to these major works, the building has received various system improvements, such as window upgrades in 2002 (installing double-pane glass), reroofing in 2007, and the recent street space permit issued in 2019.

The property has experienced regular maintenance and response to local concerns, as evidenced by multiple 311 calls in late 2024 and early 2025, though most of these related to external issues such as graffiti, parking enforcement, and street lighting rather than building-specific problems. The building's documented history suggests a pattern of proactive maintenance and timely response to infrastructure needs, with no recorded major safety violations or persistent building-related issues over recent years.
