4-8 Saturn St, San Francisco, CA 94114

The three-unit, two-story multi-family residential building at 4-8 Saturn Street in Corona Heights, owned by Wong Jule Ann, was constructed in 1908 and has experienced several significant maintenance events, most notably a serious structure fire in February 2014 that rendered the top floor unit unsafe for occupancy. The fire incident led to multiple building permits for repairs, including a major $100,000 restoration project in March 2014, followed by additional glazing work on the third floor windows in October 2014, totaling $20,000. The building's renovation history includes substantial electrical upgrades in May 2015 with the installation of new wiring, receptacles, switches, lights, smoke detectors, and a new main service with four meters, along with comprehensive plumbing work comprising kitchen, bathroom, and laundry room remodels.

The property has undergone various maintenance work over the years, including addressing dry rot issues in 2011 and 1992, and routine inspections in 2002 and 2011. The building's history includes several code violations and complaints, particularly around fire safety. In 2011, violations were documented regarding egress obstruction and fire extinguisher requirements, while the 2014 fire incident prompted multiple violation notices requiring monitoring fees.

There was also a complaint regarding construction noise in 2014, though this was marked as not active. Earlier concerns about the building's unit configuration were recorded in 2003, when there were allegations of an illegal third unit, though this complaint was eventually closed. The property has been subject to routine fire safety inspections, and two fire complaints were recorded in 2012 and 2014, with the latter indicating the building was open and vacant, though the situation was addressed within days. Recent activity at the property, recorded through 311 calls, primarily relates to external issues such as street cleaning, graffiti removal, and debris management, with the most recent service requests dating from 2023-2024 being primarily related to public spaces around the building rather than the building itself.
