1117 Castro St, San Francisco, CA 94114

The two-unit residential building at 1117 Castro Street in Noe Valley is a two-story flats and duplex structure built in 1900, currently owned by Hudson & Terry Lanier (2003). The property has a documented history of recurring sewer system issues, with six reported incidents between 2019 and 2024, including the most recent sewage back-up discharge from a side sewer vent in September 2024 and similar incidents in 2023, 2021, and 2019.

These sewer problems appear to be a persistent challenge for the building, requiring multiple interventions by PUC Sewer Operations. The building's maintenance history includes some significant improvements, such as a $19,300 reroofing project completed in 2014.

Earlier maintenance work from the 1990s, which is no longer active, included replacement of the front stairs and installation of a new garage door in 1994 (permit expired), as well as the replacement and painting of Victorian trim in 1993 (permit expired). The property has experienced minimal non-sewer-related incidents, with occasional reports of graffiti (most recently in September 2023) and an overflowing city garbage can in July 2023, both of which were promptly addressed. Overall, while the building has undergone some renovations over the years, the recurring sewer issues stand out as the most significant and persistent maintenance concern.
