1124 Leavenworth St, San Francisco, CA 94109

1124 Leavenworth Street is a three-story multiple-family residential building located in San Francisco's Nob Hill neighborhood. Built in 1922, this five-unit apartment building has undergone several significant safety improvements in recent years, most notably completing a mandatory soft-story retrofit in 2017 (with a revision in 2022) that cost approximately $90,000, which included the installation of a Simpson moment frame. The building has also faced various maintenance and safety challenges, including multiple building violations in 2016 related to fire safety, stair repairs, lighting, and pigeon control, all of which were abated by January 2010.

More recent issues include a 2022 complaint regarding short-term corporate housing violations, citing problems with radiators, smoke detectors, exposed wires, and window locks, as well as non-compliance with soft-story requirements reported in 2019 (abated in 2024). The building's maintenance history reveals attention to basic infrastructure needs, including reroofing projects in 1991 and 2008, window replacements in 1997 and 2003, and compliance work following physical inspections. Boiler permit renewals have been an ongoing concern, with multiple complaints between 2004 and 2016.

The property has also been subject to several routine inspections and building complaints over the years, including a 2015 incident involving neighboring property damage. Recent zoning records indicate some controversy over illegal short-term rentals, which was reportedly addressed by city officials. The building achieved "Work Complete, CFC Issued" status under the Soft Story program and is currently classified under the "Apartment 5 to 14 Units" building class.
