535 18th Ave, San Francisco, CA 94121

The two-unit residential building at 535 18th Avenue in the Central Richmond neighborhood is a two-story flats and duplex structure built in 1915, currently owned by the Kathryn Gaw Living Trust. The building's documented history shows relatively few major interventions, with the most significant being two fire-related incidents in 1991—one of which was completed with repairs while another was withdrawn—and a reroofing project completed in 2008 at a cost of $6,500.

The property has experienced several infrastructure and environmental issues in recent years, particularly in 2023-2024, including multiple incidents of debris and waste removal needs in the surrounding area, with three incidents involving garbage or furniture and one involving human waste or urine in 2024. Of particular note is a sewage backup incident in January 2024 that was resolved by PUC Sewer Operations.

There are currently two open infrastructure issues near the property: a pavement defect reported in August 2023 and a tree maintenance concern regarding lifted sidewalk tree roots reported in August 2023. Previous issues have included parking violations on the sidewalk (2022) and a damaged tree with hanging limbs (2022), both of which were resolved. The limited number of building permits on record suggests relatively stable building conditions, though the recent pattern of infrastructure issues in the immediate vicinity may warrant attention.
