157 11th Ave, San Francisco, CA 94118

The property at 157 11th Avenue is a two-unit, two-story multi-family residential building constructed in 1974, classified as a Flats & Duplex structure and currently owned by Wong Jack J S. The building has undergone several noteworthy maintenance and infrastructure improvements over the past decade.

Most recently, in October 2016, both street space work was permitted (cost: $1) and a trenchless sewer replacement project was completed, extending from the house trap to in front of the garage. Two significant incidents relating to sewer infrastructure were documented in October 2016, including a sewage backup incident that was resolved by the PUC Sewer Operations team.

Prior to these developments, the building underwent a complete re-roofing project in November 2014, representing a substantial investment of $18,500 in building maintenance. The property's condition has been relatively stable since these improvements, though there was one documented pavement issue in August 2020, which was reported to the Department of Public Works and subsequently transferred to the Public Utilities Commission for assessment. This incident of pavement defect, specifically related to a "M/S Depression," represents the most recent infrastructure concern on record, occurring nearly three years ago.
