17-19 Valparaiso St, San Francisco, CA 94133

The two-unit residential building at 17 Valparaiso Street in Russian Hill is a two-story flats and duplex structure built in 1912, currently owned by Clayton K. Tang. The most recent significant maintenance activity was completed in September 2023, involving a reroofing project costing $13,273, which has been successfully completed.

This follows a substantial window upgrade that occurred in November 1987, when aluminum windows were installed, representing one of the few documented improvements to the property's envelope over the past several decades. The building's maintenance history from 2011 onwards shows regular attention to basic infrastructure, particularly regarding street-level issues. The most recent incidents, occurring in July 2022, involved three separate reports of loose garbage requiring general cleaning of the street area, all of which were resolved.

Prior to these, there was one report in April 2020 concerning hazardous materials (specifically oil/paint/other liquids) in the street area, which was also resolved. Earlier records show a minor incident with an abandoned vehicle in October 2016 that was resolved when the vehicle was no longer present, and a streetlight issue in November 2011 that was promptly addressed by PG&E with lamp replacement. While these incidents reflect general urban maintenance issues rather than specific building concerns, they do provide context about the building's immediate surroundings and the local infrastructure maintenance responsiveness.
