1720 Leavenworth Street is a 3-story, 12-unit multi-family residential building located in Russian Hill that was built in 1925. The property, currently owned by 1720 Leavenworth G1 LP, has undergone significant renovations in recent years, most notably the addition of three accessory dwelling units (ADUs) on the ground floor in 2020-2023, including comprehensive updates to the building's fire alarm and sprinkler systems. As of September 2023, the building has completed multiple fire safety upgrades, including the installation of low-frequency horns in sleeping areas and the relocation of fire alarm control systems, totaling approximately $12,500 in improvements.

The building has maintained compliance with the mandatory Soft Story Retrofit Program, achieving "Work Complete" status as a Tier 4 building, though there was a violation notice filed in May 2023 regarding improper permit removal and monitoring fees, which was abated by June 2023. Recent complaints in 2024 have included minor issues with common area maintenance, though these were promptly addressed. Historical building concerns from 2008 and earlier regarding gas meter instructions, fire escape maintenance, and garbage receptacle placement have all been resolved. The property has experienced routine fire alarm system activations over the years, typically related to system malfunctions rather than emergencies, with the most recent incident being resolved the same day in September 2023.

The building's renovation history shows substantial investment in modernizing and expanding the property, with numerous unit upgrades including kitchen and bathroom remodels, washer/dryer installations, and infrastructure improvements such as a 400-amp service upgrade and new plumbing systems. In 2022-2023, significant work was performed to install fire safety systems throughout the building, including sprinklers, alarm modifications, and related electrical work. The property has also addressed several safety and compliance issues noted by housing inspections, including fire safety equipment maintenance, though some violations have required formal notices before resolution. The most recent 311 calls primarily relate to exterior maintenance issues such as signage and waste management.
