3915 23rd St, San Francisco, CA 94114

The two-unit multifamily residential building at 3915 23rd Street in Noe Valley, owned by Twal Sameh S & Mary S, is a two-story structure built in 1902. The building has undergone several significant modifications over the years, with the most notable being an unauthorized construction incident in late 2003 that led to multiple violations.

These violations, filed in November 2003, involved an unauthorized rear room addition and questions concerning the legality of an existing ground-floor kitchen. The violations remained unresolved until September 2013. Following this, legitimate improvements were made, including a 2003-2004 permitted horizontal addition that rebuilt a second-floor laundry room and added a new third-floor balcony, along with electrical work to install new switches, lights, and receptacles.

More recent maintenance includes a reroofing project in 2015 costing $10,000. The property has experienced typical urban neighborhood issues over the years, including three 311 calls in recent years: a non-offensive graffiti incident on a signal box in December 2023, a sidewalk parking violation in January 2019 that resulted in a citation, and a pavement defect reported in May 2016. The building's historical records show various improvements and modifications consistent with standard residential maintenance and upgrades, though there was a notable period of regulatory non-compliance in 2003-2013 that has since been resolved.
