179 20th Ave, San Francisco, CA 94121

The 4-unit, 2-story apartment building at 179 20th Avenue in the Lake--The Presidio neighborhood, owned by the Wing Fai Ng Revocable Living Trust, was constructed in 1965 and has undergone several significant maintenance and safety improvements over the past two decades. Most notably, the building experienced a serious cluster of fire safety violations in 2002, when multiple issues were documented including inadequate smoke detectors in stairways and the lobby, problems with smoke enclosure door closers, a malfunctioning fire escape drop ladder, and combustible storage concerns.

All these violations were officially abated by May 16, 2008. The building has received two major structural upgrades: a $15,000 siding and plywood replacement project completed in 2012 to address dry rot at the left rear of the building, and a $7,000 reroofing project completed in 2010.

More recently, there have been several routine municipal service calls near the property, including street cleaning (in 2019 and 2023) and a parking enforcement issue (in 2021), though these are unrelated to building conditions. The building's documented history shows that while there were significant safety concerns in the past, these have been addressed and there have been no subsequent violations of this nature. The most recent building maintenance appears to be primarily focused on routine upkeep rather than addressing emergency repairs or structural issues.
