1445 Leavenworth St, San Francisco, CA 94109

1445 Leavenworth Street is a three-story, six-unit multi-family residential building constructed in 1910 in San Francisco's Nob Hill neighborhood. The property has undergone significant renovations and faced multiple compliance issues in recent years, most notably an active investigation regarding unpermitted construction work in Units 1 and 6 during 2021, which involved unauthorized kitchen and bathroom renovations, removal of plumbing fixtures, and improper electrical work.

The building's soft-story retrofit status is currently listed as Non-Compliant (Tier 3), indicating failure to meet mandatory seismic safety requirements, with an active complaint regarding this violation filed in 2019. The building has seen substantial improvements through various permits over the years, including multiple documented kitchen and bathroom remodels between 2015 and 2021, electrical system upgrades with 60-amp sub-panel installations, and the proposed addition of a seventh studio unit in 2016 (though this application remains unresolved as "Filed").

Historical violations from 2005 revealed multiple maintenance issues, including lead paint hazards, security concerns, and fire safety violations, though these were subsequently abated. The property has experienced several fire safety inspections, with the most recent combustible materials violation in 2022 being corrected. While the building has undergone significant modernization efforts, including the installation of tankless water heaters and gas fireplaces, the presence of active code violations and the non-compliant soft-story status warrant careful attention to ongoing building safety considerations.
