1501 Leavenworth St, San Francisco, CA 94109

1501 Leavenworth Street is a 4-story, 24-unit multi-family residential building located in San Francisco's Nob Hill neighborhood, built in 1909 and currently owned by 1501 Leavenworth Street LLC. The building has undergone several significant structural improvements, including a completed soft-story retrofit in 2016 (Tier 2) with associated seismic strengthening, and most recently, a kitchen and bathroom remodel in 2021 following a construction complaint.

The property has experienced various maintenance and safety-related issues over its history, including multiple fire safety violations (most recently a sleeping area requirement violation in December 2023) and routine housing inspections that revealed security and fire safety concerns, all of which were eventually addressed and closed. Recent concerns at the property include multiple 311 calls in late 2024 regarding garbage and debris on the property and surrounding area, with the most recent being related to noise in October 2024. The building's history includes three instances of carbon monoxide detector activation (though all with no CO detected), one contained cooking fire, and several false alarms.

Records show consistent maintenance efforts, with recent plumbing and electrical work completed in 2021, including kitchen and bathroom updates and gas line installations. Historical permits reveal past roof work (1990), and the building has maintained compliance with seismic safety requirements through its Tier 2 soft-story retrofit completion. While historical violations and complaints have been numerous, they appear to have been systematically addressed and resolved, with no active violations currently outstanding except for the recent sleeping area requirements citation.
