470 Collingwood St, San Francisco, CA 94114

The three-story, nine-unit multi-family residential building at 470 Collingwood Street, owned by Kenneth B. Henisey and constructed in 1965, has undergone significant recent activity, particularly in Unit 9. As of September 2024, there are active complaints regarding unauthorized construction work in Unit 9, including removal of walls and structural beams, common plumbing rerouting, and electrical work without proper permits, despite earlier approved permits for kitchen and bathroom renovations, including new showers, electrical work, and plumbing fixtures.

The building has a documented history of attention to safety and structural integrity, having completed a mandatory soft-story retrofit in 2016 (Tier 3, CFC Issued) and addressed various fire safety issues over the years, including alarm system maintenance, extinguisher servicing, and combustible materials concerns, all of which were eventually corrected. The building's maintenance record shows regular updates and improvements to individual units, with completed projects including steel beam repairs in the garage (2020), and various unit renovations between 2006 and 2024, though some proposed projects have been withdrawn or completed without proper permits. The property has experienced recurring issues with parking violations in the vicinity, as evidenced by multiple 311 calls between 2022 and 2025, primarily related to driveway blockages.

Historical records show the building has been responsive to maintenance requirements, including final inspections for multiple units (5, 6, 8, and 9) and various renovation projects across different units, suggesting ongoing property upkeep. The building's historical violations from 2000-2006 have all been marked as abated, including fire extinguisher and smoke door issues, indicating these problems were resolved in accordance with compliance requirements. While the recent unauthorized work in Unit 9 has raised concerns about proper permit adherence, the overall pattern of building improvements and safety compliance suggests active property management, though some recent work has occurred beyond the scope of approved permits.
