40 Buchanan St, San Francisco, CA 94102

The 12-unit, 3-story apartment building at 40 Buchanan Street in Hayes Valley, owned by Manfred & Sheila C Angstenb, has undergone several significant improvements since its construction in 1927. Most notably, the building completed its mandatory soft-story seismic retrofit in 2015 (Tier 3), ensuring improved structural safety. Recent maintenance includes a significant reroofing project in 2021 costing $13,500, and a complete renovation of Apartment 12's kitchen and bathroom in 2019, including new cabinets, countertops, fixtures, and tiles, with plumbing work also conducted in 2019.

The building's infrastructure has seen major upgrades, including a new 200-amp electrical service installation in 2005 and the replacement of a steam boiler in 2012. The property has experienced periodic maintenance issues and violations over the years, with some clusters of problems. A significant set of violations was recorded in 2002, including issues with the fire alarm system, stair repairs, fire safety equipment, and security features, though these were all abated by October 2002. More recently, in 2020, the building received fire code violations that were related to fire extinguisher maintenance and building owner contact requirements, which were subsequently abated.

The building has undergone several routine inspections and maintenance interventions, including repairs to backstairs due to dry rot in 2002 and shoring work for an adjacent property in 2011. Recent complaints have been relatively minimal, with the most recent being a common areas complaint in 2023 that was resolved by the end of May 2023. There has been one recent investigation regarding possible illegal short-term rentals for Unit 5, which was marked as "Closed - Abated" in Planning Records. The property has experienced recurring issues with parking enforcement, particularly regarding blocked driveways, with multiple citations issued between 2022 and 2024.
