852-856 Union St, San Francisco, CA 94133

The 852-856 Union Street building, a three-story multi-family residential structure built in 1910 in Russian Hill, is currently managed by the Wong Family Trust and contains three units. The property has experienced several significant maintenance and safety concerns in recent years, with the most pressing issue being an active building violation filed in May 2024 regarding stripped interior walls, though building permits have since been filed for drywall reinstallation and interior remodeling. Earlier complaints from December 2019 revealed multiple safety issues including heating system failures, non-functional smoke detectors, electrical problems, and concerns about an asbestos-containing fireplace.

Recent construction activity in 2024 has raised concerns about unpermitted work and safety compliance, as evidenced by multiple 311 calls regarding construction, heating system upgrades, and electrical work. The building's maintenance history shows various infrastructure improvements and repairs, including a complete reroofing in 2001 (completed), sidewalk repairs (expired permit), and ongoing work in 2024 involving water heater replacement, electrical sub-panel installation, and plumbing system updates. The property has also experienced recurring plumbing issues, as documented by multiple complaints in 2003 regarding water leakage into the garage.

Though there were several fire department responses to the building, none resulted in significant incidents or civilian injuries, and a fire complaint from 2019 was determined to have no merit. The building's management has faced regulatory scrutiny over the years, with notable violations regarding lead paint concerns in 2012 and various safety deficiencies in 2019, though most of these issues were officially abated. Recent construction activity has prompted multiple 311 calls regarding construction work and safety compliance on the property, indicating ongoing concerns about building maintenance and code compliance.
