3907-3915 Balboa St, San Francisco, CA 94121

The 4-unit, 2-story multi-family residential building at 3907-3915 Balboa Street in the Outer Richmond, built in 1921 and currently owned by Eric W. Tang, has undergone several significant modifications and experienced various maintenance issues over the years. Most notably, in 2017, unpermitted rooftop access via rear stairs and associated safety features were professionally removed and modified, including replacing a door with a window and addressing guardrail concerns, at a cost of $3,000.

The building faced more serious concerns in 2007 when a complaint was filed regarding severe mold, mildew, and water damage, though it was abated within approximately one month. Earlier exterior maintenance work included siding replacement across two and a half sides of the building in 2006, with additional repairs for dry rot, and a roof replacement documented in 1993. The property has experienced three recorded fire incidents, though none resulted in civilian injuries; these included a cooking fire contained to a container, a CO detector activation due to malfunction, and a natural gas-related response, along with one false alarm.

Recent history shows a pattern of outdoor maintenance issues, with multiple 311 calls in late 2024 regarding garbage and debris on nearby streets and sidewalks, as well as instances of graffiti. While these exterior concerns are not directly related to the building's habitability, they may impact the general environment around the property. The most recent building-related work was completed in 2017, and all known building permits and complaints have been resolved or closed.
