47 Naples St, San Francisco, CA 94112

The two-unit, two-story multi-family residential building at 47 Naples Street in the Excelsior neighborhood, owned by Amparo Cruz, has experienced persistent sewer-related issues over the past three years, with the most recent incidents occurring in late 2024. The property has documented multiple sewage discharge events from side sewer vents between 2022 and 2024, including four such incidents within a three-month period from September to December 2024.

Additional concerns include flooding on the street in January 2022, where it was determined that the issue originated from the property's plumbing rather than city infrastructure. The building, constructed in 1895, has undergone several roofing projects over its lifetime, including a completed reroofing in 1988, an additional reroofing with plywood installation in 1989, and a more recent roofing project in 2007 costing $4,800.

A street space and sidewalk permit was also issued in 2008 for minimum cost. While the building has met basic maintenance requirements through permit issuance, the recurring sewer issues represent the most significant challenge to resident comfort and building infrastructure in recent years.
