376-380 31st Ave, San Francisco, CA 94121

The three-unit multi-family residential building at 376-380 31st Avenue in the Central Richmond district, owned by Raynell H. and Mildred B. Lee, was constructed in 1915 and stands two stories tall.

The property has undergone several significant improvements over the years, with the most substantial being a 2009-2013 project that included a horizontal addition for unit 380, installation of 19 fire sprinkler heads, and various interior renovations costing approximately $74,000. Other notable improvements include garage door replacement in 2018 ($2,800), reroofing in 2014 ($9,700), and multiple interior modifications in 1996. A concerning active complaint from March 2019 alleges unauthorized demolition work on the first floor, described as "shady construction in the garage" with dangerous equipment on the sidewalk, though this issue appears to have received a permit for investigation.

The building has experienced several routine housing inspections, with a significant cluster of violations recorded in August 2008 related to safety and maintenance requirements, including missing handrails, fire extinguishers, and gas meter instructions - though all these violations were abated by October 2008. Recent building history shows proper attention to fire safety improvements, with a complete installation of a new fire sprinkler system in 2013 and associated electrical and plumbing work. While the property has maintained active permits for various improvements, including the recent inspection of unauthorized work, the building's historical record indicates regular maintenance and upgrading of systems, particularly focusing on safety features such as sprinklers and structural improvements.
