1155 Leavenworth St, San Francisco, CA 94109

1155 Leavenworth Street is a 21-unit residential building located in Nob Hill, constructed in 1911 and classified as a TIC building with 15+ units. The property has undergone several significant infrastructure improvements in recent years, most notably the recent installation of a new fire alarm system in April 2024 (with related electrical work completed in June 2024) costing over $33,000 to comply with current safety codes. The building completed its mandatory soft-story retrofit in 2016 at a cost of $100,000, demonstrating compliance with seismic safety requirements. Recent maintenance work includes plumbing upgrades with waste line replacement for multiple sinks in 2021 and cold water pipe replacement in 2013.

However, there have been several fire safety violations in 2023 related to sleeping area requirements, alarm systems, and fire extinguishers, though some of these violations have been abated. The building has experienced historical issues with heating systems, particularly in 1997 when multiple complaints about lack of heat were filed and subsequently resolved. The property has a documented history of compliance with various safety and maintenance requirements, including a completed roof replacement in 2018 ($30,000). While there were several building violations recorded between 2001-2005 related to security and fire safety (including issues with fire escape ladders and smoke detectors), these were abated.

Recent complaints in 2022 regarding an unpermitted boiler appeared to be resolved quickly. The building has experienced four fire-related incidents between 2019-2023, including a gas leak and several alarm system activations, though none resulted in civilian injuries. A recent short-term rental violation investigation was conducted in 2023-2024, resulting in penalties and cancellation of unauthorized listings. The property demonstrates regular maintenance and upgrades to essential systems, though the recent fire safety violations highlight ongoing compliance requirements in this area.
