163-165 18th Ave, San Francisco, CA 94121

This three-story, multi-family residential building located at 163-165 18th Avenue in the Lake-Presidio neighborhood is a duplex structure built in 1914, currently owned by the Yeong Fung Y Revocable Trust. The building has undergone several significant improvements over the past few decades, most notably a comprehensive window and siding upgrade in 2011 that involved replacing 15 windows with energy-efficient fiberglass frames and installing new hardi siding on the upper front and side walls, costing $35,000.

Prior to this, similar exterior improvements were made in 2009 with the installation of vinyl siding and window replacements on the back walls, valued at $10,900. The building's maintenance history shows attention to structural integrity, with completed work in 1995 to address dry rot in the siding, and two earlier projects in 1990 and 1988 that included reinforcing terrace stairs and reroofing, respectively. The property has experienced multiple parking-related issues in recent years, with several citations issued for sidewalk parking and driveway blocking between 2020 and 2024, though these are external to the building's management.

More concerning is an open issue from February 2021 regarding tree root damage to the sidewalk, which appears unresolved as of the latest data. While there have been several reports of abandoned vehicles in the vicinity between 2017 and 2019, all were promptly addressed by authorities, and two sidewalk parking violations in October 2022 were resolved through citations. The building's permit history indicates regular maintenance and upgrading of exterior elements, suggesting active property management, though the presence of an unresolved tree root issue may warrant attention.
