405 2nd Ave, San Francisco, CA 94118

The 5-unit, 3-story multi-family residential building at 405 2nd Avenue in San Francisco's Inner Richmond district, owned by Wong Nellie Trust, has undergone several significant improvements and faced some notable compliance issues since its construction in 1921. Most recently, in response to a November 2023 violation, the building underwent window replacements, installing 56 new wood aluminum-clad windows with Pella systems at a cost of $50,000, which were properly permitted following an earlier unauthorized installation. The building has seen substantial safety upgrades, including a complete fire alarm system overhaul in 2020 with the installation of new smoke detectors, pull stations, and low-frequency sounders to meet current fire safety requirements ($9,500).

Earlier maintenance includes a roof replacement project completed in 2014 ($31,600) and the installation of a new horizontal folding gate in 2020 ($8,000). The property has maintained regular housing inspections, with most issues being routine or promptly resolved, though there were past concerns in 2001 regarding an unauthorized dryer installation in one unit. The building has experienced several fire alarm activations over the years, all of which were determined to be either unintentional or system malfunctions, with no civilian injuries recorded.

A notable fire incident occurred (classified as an "111 Building fire") but its cause was listed as "2 Unintentional" with no civilian injuries reported. The property has had some historical compliance matters, including a 1995 incident involving a blocked rear exit, though most recent violations have been promptly addressed. Surrounding infrastructure issues have been documented through 311 calls, primarily relating to street cleaning and parking meter concerns, with the most recent being utilities and maintenance issues in 2024. The building's recent history suggests improved compliance with building codes and regulations, particularly following the 2023 window violation, which was addressed through proper permitting and installation procedures.
