1490-1494 Jackson St, San Francisco, CA 94109

The three-unit multi-family residential building at 1490-1494 Jackson Street in Nob Hill, owned by Nga Ling Wong Jow Tr, was constructed in 1911 and underwent significant renovations between 2009 and 2012. The most substantial project occurred in 2009 when a fourth floor was added, along with an expanded porch area, rear stair enclosure, and a new efficiency unit behind the garage, during a major $500,000 renovation that also included updates to the foundation, mechanical, electrical, and plumbing systems.

The building received comprehensive safety upgrades, including the installation of a fire sprinkler system with 71 heads (completed in 2011) and a manual fire alarm system with multiple safety features (completed in 2012). Subsequent modifications included kitchen relocations, window replacements, and closet changes on various floors, all completed under permits from 2012. More recent history shows primarily external issues, with several 311 calls in 2020-2024 mostly related to illegal parking, with eight instances of reported violations resulting in citations.

There have been few recent building-related complaints, with the most recent being a garbage and debris report in December 2024. The extensive renovation work completed between 2009-2012, including new furnaces, chimneys, electrical systems, and life-safety improvements, suggests the building received significant modernization and safety upgrades during that period, with all major permits showing as completed. The property is now fully transitioned to its updated configuration with no outstanding permits or significant building-related issues in recent years.
