418-420 2nd Ave, San Francisco, CA 94118

The three-unit, three-story multi-family residential building at 418-420 2nd Avenue in the Inner Richmond, owned by Sylvia H. Chow, was constructed in 1986 and has undergone several significant improvements over its lifetime. In 2006, the building received substantial window upgrades with the installation of vinyl retrofit windows and sliding patio doors ($22,200), along with new vinyl siding that replaced the existing wood siding ($52,000). The building was originally constructed with important safety features including fire sprinklers and a reinforced concrete block wall in 1984.

A routine safety inspection in December 2015 identified multiple safety concerns that were subsequently addressed by the end of 2015, including the need for seismic bracing of the hot water heater and repairs to emergency exit lights in public areas. The building has a documented history of maintenance and safety inspections, with several complaints and violations being recorded between 2004 and 2015, though all were ultimately resolved. These included issues with emergency lighting, gas utility requirements, smoke detectors, emergency exits, and wood stairs and decks. A single hazardous materials complaint was recorded in July 2007 and resolved by August of the same year.

Prior to the 2015 inspection, the last documented routine inspection was in 1999. In recent years, the area around the building has experienced numerous reports of abandoned vehicles, with multiple 311 calls between 2023 and 2024, though most have been determined to have no merit or resulted in vehicles being gone upon inspection. The building's permit history demonstrates ongoing maintenance and upgrading of building components, particularly during its first two decades of existence. The recent clustering of abandoned vehicle reports in the vicinity might indicate ongoing parking issues in the neighborhood, though most reports have been determined to involve non-abandoned vehicles. The most recent building-related activity on record was the routine safety inspection in 2015, and there have been no recorded violations or complaints in recent years pertaining to the building's safety systems or general conditions.
