1404-1406 Leavenworth St, San Francisco, CA 94109

The property at 1404-1406 Leavenworth Street is a 3-story, 2-unit multi-family residential building located in San Francisco's Nob Hill neighborhood, currently owned by Matthew and Jessica Diamond. Built in 1908 and classified as a Flats & Duplex structure, the building has undergone several maintenance and improvement attempts over the years. Most notably, in 2019, a significant proposal was filed to remodel and add to the existing structure, transforming it into a 5-story building with 3 units and a garage/lobby area, though this project is currently listed as "On Hold" in the planning records.

Previous building maintenance included repairs for dryrot damage in 2011 and sidewalk repairs in 2001. Recent activity at the property (2023-2024) has primarily involved external issues, particularly regarding street maintenance and parking concerns. There have been multiple reports of garbage and debris on the street, illegal parking, and abandoned vehicles in the vicinity, though these are external neighborhood issues rather than building-specific concerns.

The building has experienced three fire safety system activations in recent years, including two false alarms and one carbon monoxide detector activation, none of which resulted in injuries or actual fire damage. The property's planning history indicates significant ambition to increase housing density on the site, with proposals to exceed current zoning allowances, though the specific permit status suggests this has not progressed to construction phase. The proposed improvements would update the building's facade, improve entry lobby features, and include new landscaping elements like planting strips and a front street tree.
