1886-1888 11th Ave, San Francisco, CA 94122

The two-unit residential building at 1886-1888 11th Avenue is a two-story flats and duplex constructed in 1960, currently owned by Woo Mai Ngan & Napon Fong. The property has maintained regular upkeep over the years, with notable improvements including a complete reroofing project in February 2022 costing $9,800, and front window replacements in 2016.

A significant incident occurred in 2005 when violations were filed regarding safety concerns, including unpermitted construction of back exit stairs and front gate security issues, though these were promptly addressed and abated by December 2005. More recent maintenance includes water heater replacement in 2016, while ongoing concerns are represented by an open sidewalk defect case from May 2022. The building's history shows regular maintenance and repairs, with roofing work completed in both 1994 and 2022, and bathroom repairs dating back to 1992.

There have been several 311 calls related to the property, primarily for noise complaints and parking enforcement issues between 2017-2022, though these are not necessarily indicative of building conditions. Historical records from 2005 indicate some issues with gate security systems and water damage (mold) concerns, though these appear to have been resolved. The most recent building improvement, the 2022 roof work, demonstrates continued investment in the property's maintenance and upkeep.
