178 23rd Ave, San Francisco, CA 94121

The two-unit multi-family residential building at 178 23rd Avenue, located in the Lake-The Presidio neighborhood, is a two-story flats and duplex structure built in 1925 and currently owned by BSJC23 LLC. The building's maintenance history shows several significant improvements, including the installation of six energy-efficient vinyl windows in 2007, which were double-pane with a U-factor of .30, meeting modern safety standards for bedroom windows.

Earlier work includes completed reroofing in 1988 and some expired electrical work from 1989 that required reinstatement in 1991. The property has experienced various maintenance and service issues in recent years, with the most notable being a sewage backup incident in November 2021 that required attention from PUC Sewer Operations.

The building's surrounding area has faced persistent challenges with street and parking conditions, including multiple reports of illegal parking, double parking, and driveway blockages between 2016 and 2024. Infrastructure issues have been addressed as needed, with records showing resolution of street lighting problems in 2017 and pavement defects in 2017. While the building itself shows reasonable upkeep with documented improvements, the surrounding area experiences regular urban challenges typical of San Francisco neighborhoods, as evidenced by the frequency and variety of 311 calls regarding street cleaning, parking enforcement, and other public service matters.
