175-177 18th Ave, San Francisco, CA 94121

The Wong Revoc Trust owns this three-story, two-unit multi-family residential building located at 175-177 18th Avenue in the Lake-The Presidio neighborhood. Built in 1914, this classic flats and duplex structure has undergone several significant maintenance and improvement projects over the years. The most recent major work involved reroofing in September 2021 at a cost of $7,200, following a historical pattern of roof maintenance that includes a 1998 reroofing project.

The building has seen various structural and safety improvements, including a sewer line section replacement in 2015, a 2003 electrical service upgrade from 100A to 200A, and multiple window installations in the 1980s. Notably, there is an active building complaint filed in October 2022 alleging unauthorized structural modifications and window installations beyond the scope of posted permits, with concerns about potential safety issues requiring engineering review. The property has experienced several infrastructure and maintenance issues, including a sewage backup incident in March 2015, and some sidewalk-related concerns with a lifted sidewalk reported to DPW in September 2019.

While there have been some parking enforcement matters reported between 2018-2019, these were primarily related to temporary parking violations rather than building safety or maintenance issues. The building's maintenance history shows consistent attention to necessary repairs, including historical attention to dry rot and stair repairs in the 1980s, though some of these earlier permits from the 1980s are now quite dated. Regular maintenance appears to be prioritized, with both the recent reroofing and the 2015 sewer line work indicating ongoing upkeep of essential building systems.
