1427 18th Ave, San Francisco, CA 94122

The two-unit residential building at 1427 18th Avenue in San Francisco's Inner Sunset neighborhood is a two-story flats and duplex structure built in 1946, currently owned by the Quon Jane Kim Revocable Trust. The property's maintenance record shows recent activity, with an issued permit for reroofing work valued at $10,000 in July 2024, suggesting ongoing property maintenance and improvement.

A historical record from 1998 indicates that the rear wall of the building was resided with Alcoa vinyl siding, though this permit has since expired. The building's exterior environment has experienced several documented incidents between 2018 and 2023, primarily involving street and sidewalk conditions.

Notable events include a 2021 report regarding sidewalk conditions and tree maintenance, where the Department of Public Works confirmed there was no immediate safety issue and mentioned the property's inclusion in the StreetTreeSF program for future repairs. Other occurrences include reports of loose garbage (January 2023), human or animal waste (May 2020), and a sidewalk parking violation (July 2018) – all of which were resolved through proper municipal channels. While these incidents suggest typical urban environmental challenges, they have generally been addressed through normal city services and don't appear to indicate any persistent issues affecting the building itself.
