1447 48th Ave, San Francisco, CA 94122

The two-story, four-unit apartment building at 1447 48th Avenue in San Francisco's Outer Sunset neighborhood, owned by David Tak Fai Chan, was built in 1958 and has undergone several maintenance and improvement projects over the past decades. Most recently, the building had a roof replacement in 2017 costing $8,000, addressing a previous code violation from that same year regarding unpermitted work.

Significant historical improvements include deck repairs in 1997, window installations in 2001, and various other maintenance work dating back to 1992 when new deck boards were installed. The property experienced multiple fire safety violations in 2001, including issues with fire escape ladders and fire extinguisher maintenance, though these were all abated by July 2001. More recent improvements include attempts to install a radiant heating system in 2021 and a shower pan in 2013, though these permits were either canceled or expired.

The building has experienced some external maintenance issues, as evidenced by multiple 311 calls between 2019 and 2024 regarding parking violations, sidewalk blocking, and garbage concerns, though these were generally resolved promptly. There is a record of one minor fire-related incident involving steam and gas in 2021, with no civilian injuries reported. The property's maintenance history shows regular upkeep and attention to building codes, with most historical violations being resolved in a timely manner.
