1658 Washington St, San Francisco, CA 94109

The 6-unit, 3-story multi-family residential building at 1658 Washington Street in Nob Hill, owned by Carol Tong, has undergone significant safety and modernization improvements since its construction in 1913. Most recently, in 2023-2024, the building received comprehensive fire safety upgrades, including a full fire alarm system modernization with low-frequency sounders in sleeping areas, and electrical panel replacements.

The building has demonstrated commitment to seismic safety through its completion of mandatory soft-story retrofit work in 2015 (with an associated cost of $60,000), classified as Tier 3, and has also maintained its mechanical systems with recent plumbing upgrades including boiler replacement in 2017. The property's maintenance history shows regular attention to infrastructure needs, such as lobby floor replacement in 2015 and roofing work in 2008. Historical building violations from 2001, including issues with smoke enclosure doors, window sash cords, and security locks, were promptly addressed and abated by July 2001.

There was one plumbing-related complaint in 2018 regarding boiler permit renewal, which was resolved within two weeks. Recent municipal response records (2020-2024) primarily document street cleaning and debris removal on public sidewalks near the property, with one ongoing sidewalk defect issue from 2017 related to tree root lifting of the sidewalk. The building's documented improvements and prompt response to violations suggest a generally proactive approach to property maintenance and compliance with safety requirements.
