526 5th Ave, San Francisco, CA 94118

The two-unit residential building at 526 5th Avenue in the Inner Richmond is a two-story flats and duplex structure built in 1908, currently owned by Herbert & Kay Frances Engel. The building's maintenance history reveals several notable concerns, particularly regarding ventilation and safety.

Most recently, in August 2024, a complaint was filed with Housing Inspection Services regarding inadequate bathroom ventilation and lack of windows, though this case is marked as "Not Active." This building has a documented history of serious safety violations, including a 1995 incident involving an illegal apartment with no means of egress, which was resolved within six months. The property has experienced various infrastructure and maintenance issues in recent years, with particular attention needed to the sidewalk area. As of 2024, there are open cases regarding a collapsed sidewalk and a missing side sewer vent cover.

The building's surroundings have faced multiple challenges with debris and hazardous materials, including several instances of garbage, dangerous glass, and hazardous waste containers reported and resolved by city agencies between 2018 and 2025. While there have been multiple incidents of graffiti (on both the building and nearby structures) and illegal postings between 2011 and 2019, these were all resolved at the time. A single fire incident is recorded where police assistance was required, but there were no civilian injuries reported and no significant damage appears to be associated with this event based on the available data.
