538 42nd Ave, San Francisco, CA 94121

The three-story multi-family residential building at 538 42nd Avenue in the Outer Richmond, owned by Nina Felshtiner, was constructed in 1989 as a two-unit structure following the demolition of a single-family home. The building's history reveals several significant events, the most concerning being a pattern of plumbing issues, with multiple sewer backup incidents reported between 2020-2023.

The property has also experienced air quality concerns, with an active violation from 2019 regarding fresh air inlet issues that has not been resolved as of the latest review. A water intrusion complaint was filed in March 2023, though this is no longer active, and there has been at least one tree maintenance issue reported in April 2019. The building's permit history shows a complex pattern of modifications and regulatory compliance efforts.

In 2000, there was a significant permit issued to legalize various spaces and remove an illegal ground floor unit, though this followed a violation complaint from 2000 about an unauthorized two-room apartment behind the garage. The original construction and subsequent modifications in the early 1990s included fire sprinkler installation and various partition installations between garage and utility spaces, though several permits expired before completion. The most recent sidewalk defect was reported in May 2024, and there has been at least one parking enforcement issue related to sidewalk parking in September 2021.
