3950 23rd St, San Francisco, CA 94114

The property at 3950 23rd Street in Noe Valley is a two-unit, two-story multi-family residential building constructed in 1885, currently owned by Harry William Arnott. The building's maintenance history shows regular upkeep of critical structures, with three significant repair projects documented: a comprehensive garage roof, railings, and deck repair due to dry rot in 2011 costing $11,847; a full reroofing in 2001 for $9,500; and dry rot repairs completed in 1986, indicating attention to structural maintenance over the decades.

The most recent major infrastructure event was a sewage backup incident in April 2018, which was resolved through PUC intervention. The property has experienced various maintenance issues and exterior concerns over recent years, with the most pressing current issue being an open case regarding a collapsed sidewalk reported in March 2021.

There have been two tree-related incidents (May 2023 and June 2020) involving maintenance needs, though the most recent inspection in September 2023 indicated the tree was in fair-good condition despite initial concerns about elm anthracnose. Other notable incidents include a sewage vent issue in April 2018, various street cleaning matters, and reports of abandoned vehicles and improper postings, all of which have been resolved. The building's management history suggests reasonable responsiveness to maintenance issues as they arise, though the persistence of the sidewalk defect and the multiple tree maintenance needs indicate some ongoing exterior maintenance requirements.
