1405 27th Ave, San Francisco, CA 94122

The two-unit residential building at 1405 27th Avenue in San Francisco's Central Sunset neighborhood is a two-story flats and duplex structure owned by Tony Yu, built in 1948.

The property's documented improvements include a significant electrical upgrade completed in 2002, which involved the installation of a 150-amp two-meter service, indicating an enhancement of the building's electrical capacity to accommodate modern requirements. More recently, in July 2019, a street space-related permit was issued with a minimal cost of $1, though the specific nature and impact of this permit are not detailed in the records.

The only reported maintenance issue in the building's history occurred in August 2012, when a flickering streetlight on a wooden pole was reported to PG&E; this was promptly addressed and resolved within a few days through the replacement of the lamp and photocell on September 1, 2012. The building's record shows no significant safety concerns or serious maintenance issues over the past decade, with the most recent work being a routine street space matter.
