2324 Market St, San Francisco, CA 94114

The 8-unit, 4-story multi-family residential building at 2324 Market Street in the Duboce Triangle, owned by 350 Third Ave LLC and constructed in 1972, has undergone numerous telecommunications infrastructure upgrades and has faced recurring regulatory issues with its boiler system. The building's roof-mounted T-Mobile facility has been modified multiple times between 2008 and 2024, with the most recent permit filed in January 2024 for antenna and equipment upgrades costing $60,000, continuing the pattern of maintenance and improvements to the cellular infrastructure.

The property has experienced ongoing boiler permit compliance issues, with multiple violations recorded between 2017 and 2021 specifically regarding the boiler's operation without proper permits, leading to active violation status as of 2021. Additional infrastructure work includes a complete fire alarm system replacement in 2013, sewer lateral replacement in 2012, and various electrical upgrades throughout the building, including work on individual apartments in 2005. Historical maintenance records show some resident concerns, including a 2012 complaint about peeling wallpaper in a bathroom and hallway, and a 2004 electrical socket issue that was quickly resolved.

The building has also had its share of street-level challenges, with recent 311 calls primarily concerning bicycle lane blockages (most recently in January 2025) and occasional reports of debris on the street. The property has undergone various administrative changes, including a successful conditional use application in 2016 to convert a vacant retail space into a professional service office, though some earlier proposals for retail space modifications were withdrawn. While the building has had its share of compliance issues, particularly with the boiler system, many of these violations have been addressed through subsequent permits and inspections, indicating ongoing management attention to building systems and infrastructure.
