112 Parnassus Ave, San Francisco, CA 94117

112 Parnassus Avenue is a 6-unit, 3-story multi-family residential building constructed in 1924 and currently owned by the Henry L Mckenzie Trust. The property has undergone several significant safety improvements in recent years, most notably a comprehensive fire alarm system upgrade completed in August 2023 that included the installation of low-frequency sounders in sleeping areas to meet current fire code requirements. The building successfully completed a mandatory soft-story retrofit in 2017, earning a Certificate of Final Completion, demonstrating compliance with seismic safety requirements.

The building's maintenance history shows regular attention to both structural and safety concerns. Previous improvements include a garage dryrot repair in 2004, reroofing projects in 1991 and 2005, and multiple streetspace permits. The property experienced some fire safety issues in 2005, when violations were documented regarding fire escape ladders and egress obstructions, though these were promptly resolved within two months.

More recent inspections focusing on the electrical system were conducted in 2023, with all necessary upgrades completed. The building's service history shows routine inspections and maintenance to address various issues, with the most recent fire system inspection in early 2024 confirming that all conditions were promptly corrected. While there have been several 311 calls regarding street-related issues around the building, these have primarily concerned public space management rather than building-specific concerns, and were typically resolved through normal city processes.
