1155 Hayes St, San Francisco, CA 94117

The 7-unit, 3-story apartment building at 1155 Hayes Street in Alamo Square, owned by Robert P. Henninger, was constructed in 1912 and has undergone several significant updates and maintenance work over the years. Most notably, the building faced multiple fire safety violations in 2023, including issues with fire extinguisher tags, gas utility shutoff tools, fire escape maintenance, and compliance documentation, though these were all abated by June 1, 2023.

A concerning active complaint from December 2020 regarding the building's soft-story status suggests potential seismic vulnerability, though historical records show various safety improvements, including a $14,000 fire alarm system installation in 2007. The building has experienced several fire-related incidents, primarily involving malfunctioning alarm systems and one confined cooking fire, with no civilian injuries reported. Recent maintenance history includes a reroofing project in 2014 costing $9,700, and various infrastructure improvements such as stair tread and stringer replacement in 2000, window replacements, and safety inspections.

Multiple 311 calls in late 2024/early 2025 indicate some ongoing issues with heat systems and graffiti on/near the property. The building's planning records show attempts to modify parking arrangements, though these proposals were withdrawn or withdrawn/approved. While the property has a history of regular safety inspections and various improvements over the years, the recent cluster of violations in 2023 related to safety equipment and procedures suggests there were periods of non-compliance with current safety standards, which have since been addressed.
