2134-2136 19th Ave, San Francisco, CA 94116

The two-unit residential building located at 2134-2136 19th Avenue in San Francisco's Inner Parkside neighborhood is a two-story flats and duplex structure built in 1946, currently owned by the Koon Fong Lew Bypass Trust. The building's documented history shows several significant maintenance and infrastructure improvements, most notably in January 2008 when an un-reinforced CMU retaining wall was replaced with a reinforced concrete wall, following a design by Mr.

Willy Tsai. That same month, the addresses of the two units were verified, with 2134 being the lower unit and 2136 the upper unit. The building's street address has experienced multiple pavement defect issues in recent years, with four cases reported between 2023 and 2024, all of which have been resolved or transferred for attention.

Other notable incidents include a sewage backup from a catch basin in November 2020, which was promptly addressed by PUC Sewer Operations, and the removal of offensive graffiti in October 2022. The property has also had routine street maintenance needs, such as Christmas tree removal in January 2022 and general cleaning in May 2017, with one pavement defect case (from September 2018) currently listed as open. The building's street space has required two permits for temporary use, one in 2018 and another in 2009, though these involved minimal costs of $1 each.
