547-549 Natoma St, San Francisco, CA 94103

The three-story, 6-unit multi-family residential building at 547-549 Natoma Street in SoMa, built in 1910, has undergone significant improvements and faced various challenges over the years. Most notably, the building completed its mandatory soft-story retrofit in 2014 at a cost of $45,000, bringing it into compliance with seismic safety requirements.

Between July and September 2014, there were multiple substantial interior remodels totaling over $200,000, including kitchen and bathroom renovations, wall removals, and structural improvements such as new posts and footings in the basement. The building underwent comprehensive plumbing updates in 2014-2015, including sewer repairs, heater replacements, and multiple shower pan installations, along with electrical work during the same period. The property has a history of building violations from January 2004, related to fire safety, sanitation, and structural issues, though these were abated by February 2005.

More recent concerns include a fire sprinkler systems violation issued in July 2024 and several triple-1-1 calls regarding garbage, debris, and encampments in the vicinity during late 2024. The building has received routine housing inspections in 2004, 2007, 2008, and 2011, with all cases ultimately being resolved. While the property has faced various maintenance and safety challenges over its history, recent improvements suggest ongoing maintenance and upgrading of building systems, though the July 2024 fire sprinkler violation indicates some areas may still require attention.
