127 Guerrero St, San Francisco, CA 94103

The two-unit residential building at 127 Guerrero Street, located in the Mission Dolores neighborhood, is a two-story flats/duplex structure built in 1904 and currently owned by the Frank Pon Bypass Trust. The building's maintenance history shows limited permitted work, with records indicating a reroofing project from 1991 and aluminum window installation from 1983, though both permits have since expired.

In 2013, residents filed a complaint regarding the installation of smaller windows that allegedly reduced ventilation by 50%. A 1994 housing inspection identified several safety concerns that were promptly addressed, including the need for handrails on interior staircases, fire extinguishers, self-closing gates, and changes to door hardware.

Recent activity at the property has primarily involved numerous reports of garbage and debris on the street outside the building. Between November 2024 and January 2025, there were at least ten separate reports of abandoned items including furniture, electronics, shopping carts, and instances of human waste or urine, most of which were marked as "Closed Case Resolved." The building's fire safety record shows a series of nine incidents, all from 2016-2018, consisting primarily of false alarms and system activations, with no recorded civilian injuries or actual fires. The most recent building-related activities relate solely to street cleaning issues rather than interior building conditions.
