846-850 Union St, San Francisco, CA 94133

The two-story multi-family residential building at 846-850 Union Street in Russian Hill, owned by Kgc Holdings LLC, was constructed in 1907 and originally contained 4 units (now 5). The property has undergone significant renovations over the years, with substantial work occurring between 2009 and 2011, including interior floor alterations, structural reinforcements (new beams, posts, and footings), and extensive plumbing and electrical upgrades. The 2011 work included the installation of new gas furnaces, ducting, water heaters, and kitchen/bathroom remodels across multiple floors.

The building's exterior received attention during this period with plans for new windows, doors, dormers, skylights, and deck improvements. More recently, the property underwent reroofing work completed in March 2024 at a cost of $19,000. The building's maintenance history shows regular upkeep, though several permits from 2011 expired rather than being completed.

The property has had two routine housing inspections (in 2000 and 2006) that were resolved without noted issues. Between 2018 and 2020, there were multiple 311 calls related to street and sidewalk cleaning issues near the property, primarily concerning waste and hazardous materials, though these were generally not directly related to the building itself and were promptly addressed by Public Works Department. A notable planning record from 2011 detailed a substantial renovation project that included seismic/structural upgrades, system improvements, and significant interior and exterior modifications.
