The property at 4123-4125 23rd Street in Noe Valley is a three-story, two-unit multi-family residential building constructed in 1906. The building has undergone several significant renovations and repairs over the years, with the most substantial work occurring between 2014-2019. This includes a major basement and rear horizontal addition in 2014, roof repairs in 2019, and window replacements on the rear facade in 2010.

The electrical system has seen substantial upgrades, including a 150-amp service panel upgrade and additional circuits installed in 2009, with the most recent electrical work in 2017 involving the installation of eighteen wall receptacles on AFCI circuits. The building's history includes some concerning maintenance issues that were addressed over time. In 2009, there was a significant complaint about rotting behind the stove, poor lighting in common areas, window problems, exterior paint issues, and a deteriorating egress walkway, which were resolved promptly.

Earlier, in 2000, there was a violation regarding a failing back porch with dry rot, which remained open until 2008. A comprehensive renovation in 2009 included updating one bathroom and kitchen with new plumbing, fixtures, and electrical systems. Recent infrastructure concerns in the vicinity include multiple reports of damaged trees (2022-2024) and a sidewalk defect (2022), though these are external to the building itself.
