4411 23rd St, San Francisco, CA 94114

The three-story, dual-unit multi-family residential building at 4411 23rd Street in Noe Valley, owned by the estate of Paul R. Guilfoyle, was constructed in 1906 and has undergone several maintenance and improvement projects over the years. The most significant recent improvement was a comprehensive bathroom remodel in 2014 at unit #4411, which included tub and sink replacements as well as tile work, with associated plumbing and electrical permits totaling approximately $9,037.

Earlier structural work included window replacement in mid-2014 (with energy-efficient vinyl frame), though several older permits from the 1980s and 1990s for stair repairs and roofing work show as expired. The property's maintenance record over the past decade reveals several infrastructure issues in the surrounding vicinity, though none directly related to the building's structure or systems. There have been multiple parking enforcement incidents near the property, with two documented cases of driveway blocking in December 2024, and one instance of sidewalk parking in April 2020.

The neighborhood experienced recurring street lighting issues, with two burnt-out streetlights reported in 2011 and 2014, both of which were promptly repaired. Other minor incidents included a non-offensive graffiti complaint on a pole in December 2013 and the resolution of a burnt-out streetlight in July 2014, all of which were addressed by the respective city services. The building appears to have received regular maintenance updates, with the most recent significant renovation focusing on modernizing unit #4411's bathroom facilities.
