1581-1587 Union St, San Francisco, CA 94123

The 4-unit, 2-story multi-family residential building at 1581-1587 Union Street in Cow Hollow, owned by the David Hd Wong Survivors Trust, was constructed in 1922 and has undergone several significant renovations and faced multiple maintenance challenges in recent years. Most notably, the building has been the subject of several active building violations since late 2022, including issues with heating systems, window problems, bathroom facilities, and maintenance concerns such as mold and water temperature irregularities. While there has been substantial recent investment in improvements, including a new roof, kitchen and bathroom remodels, electrical upgrades, and heating system installations totaling over $200,000 in 2024, these renovations have caused considerable disturbance to neighboring residents.

Complaints regarding excessive noise and construction-related disruptions were fielded throughout 2024, with multiple reports of loud construction work and music during renovation periods. The property has a history of maintenance issues, with violations related to fire safety, mold, and general building upkeep documented as far back as 2004, though many of these earlier violations were resolved within weeks. Recent infrastructure improvements have included the installation of electrical wall panel heaters, new subpanels, and high-efficiency gas furnace systems.

External to the building itself, there have been reports of flooding, sanitation issues, and other maintenance matters affecting the surrounding area. The building's recent permit activity shows significant investment in system upgrades and renovations, including the installation of three electrical wall panel heaters in each bedroom and living room, reroofing work completed in March 2024, and comprehensive kitchen and bathroom remodeling projects. The property has also seen some troubling maintenance patterns, including a rodent infestation complaint filed in March 2023 and ongoing violations from late 2022 covering a range of issues from heating systems to window functionality. Recent construction work has been particularly controversial, generating multiple complaints about noise and disruption to neighboring properties, though many of the immediate housing violations affecting the building's units appear to be actively addressed through recent renovation work.
