1131-1133 Treat Ave, San Francisco, CA 94110
The Barrango Family 2016 Trust owns this two-unit, two-story multi-family residential building located at 1131-1133 Treat Avenue in the Inner Mission neighborhood. Built in 1900, this flats/duplex property has undergone several notable maintenance and compliance updates over the years. Most recently, in August 2024, a $12,000 re-roofing project was completed.
The building experienced significant maintenance issues in June 2018, when multiple violations were documented including problems with stairs, doorknobs, windows, smoke detectors, carbon monoxide alarms, lighting, and plumbing fixtures. These violations, which raised safety and habitability concerns, were all addressed by September 2018 through various repairs and electrical improvements, including new light fixtures and electrical compliance work. Earlier electrical upgrades include the installation of dedicated 20-amp circuits for kitchen appliances in 2005. The property's maintenance history shows regular attention to structural elements, with another re-roofing project recorded in 1991, though that permit has since expired.
Recent history of the property shows some external maintenance attention, with multiple 311 calls related to street cleaning and parking issues between 2012 and 2023, though these are more related to public space than the building itself. The most recent building-related complaints were addressed through proper channels and resolved, suggesting improved management response to maintenance issues. It's worth noting that during the 2018 inspection period, there were concerning comments about back staircase safety and the absence of basic safety features like smoke detectors, though these issues were subsequently resolved. The property appears to have undergone significant safety improvements as part of addressing the 2018 violations, including the installation of required safety equipment and repairs to various building systems.
