109 Highland Ave, San Francisco, CA 94110

This two-unit, two-story multi-family residential building located at 109 Highland Ave in Bernal Heights was built in 1924 and is currently owned by Rigoberto Canchola. The property has undergone several significant modifications over the years, including basement renovations in 2002 that added a family room, storage room, and half bathroom, followed by reinforcement work to the basement walls. A concerning complaint was filed in September 2012, which noted multiple safety hazards including the lack of smoke detectors, inadequate heat, a blocked emergency exit, accumulated garbage, mold issues, and allegations of an illegal basement unit with improper bathroom and kitchen facilities.

More recently, in late 2022, there was a sewage backup incident reported and resolved through the Public Utilities Commission. The property has also seen various infrastructure improvements attempted, including a cancelled solar panel installation project in 2015. The building's recent history shows a pattern of maintenance and safety concerns, particularly in the past decade.

Between 2022 and 2024, there have been multiple reports of hazardous materials, including oil or paint substances, and two instances of loose garbage accumulation in the vicinity of the property. The property's parking area has been the subject of several complaints between 2022 and 2024, with reports of illegal parking and blocked driveways, though these are external issues affecting the property rather than internal building concerns. The documented permits and work performed on the building suggest some attention to structural improvements, particularly to the basement area, though the 2012 complaint raises questions about the overall maintenance of basic safety systems such as heating and smoke detection.
