3740-3744 20th St, San Francisco, CA 94110

The three-unit multi-family residential building at 3740-3744 20th Street, owned by Dennis and Mary Reager, has experienced several maintenance and safety-related issues since its construction in 1908. The building's maintenance history shows attention to structural issues, with significant repairs made to address dry rot in stairs (2002, 2015) and electrical upgrades including an underground conversion to 150-amp service in 2003.

The property underwent two routine apartment house inspections in 2002 and 2007, during which several violations were documented, including problems with stairs, egress obstruction, and fire safety equipment, though these were all subsequently abated by November 2002. Recent history from 2018 to 2024 shows no major building-specific violations, though there have been multiple 311 calls regarding the immediate exterior area, primarily related to sidewalk conditions, waste cleanup, and street maintenance.

The building has experienced several infrastructure challenges, including sewer line repairs in 2013, and has undergone various exterior maintenance including street space and sidewalk repairs in multiple years. The property has been subject to regular maintenance requirements, with particular attention to stair safety and exterior elements, while the fire safety system appears to have experienced at least one CO detector malfunction, though no resulting injuries were reported. Recent sidewalk inspections have noted ongoing issues with tree root damage leading to lifting, particularly during 2009-2017, though these infrastructure concerns appear to have stabilized in recent years.
