3420 Pierce St, San Francisco, CA 94123

The 6-unit, three-story apartment building at 3420 Pierce Street in the Marina district, owned by Thelma Gallegioni, was constructed in 1927 and has undergone several significant improvements over its lifetime. Most importantly, the building completed a seismic retrofit in 2016, costing $60,000, demonstrating compliance with the wood frame seismic retrofit program and achieving "Work Complete, CFC Issued" status under the Tier 3 soft-story program.

Other notable improvements include street space permits in 2016 and 2012, a completed brick-to-stucco exterior renovation in 1989 (covering an 8x25 foot area minus the garage), and a reroofing project initiated in 1995. The building had four violations documented in May 2007, all of which were promptly addressed and abated by June 21, 2007, including the installation of gas utility shutoff tools and self-closing devices at exterior doors.

Recent 311 calls from 2023-2025 have primarily involved external issues such as parking concerns, with several reports of vehicles parking illegally or abandoned near the property, though enforcement officers were often unable to locate the vehicles. There are currently two open tree maintenance cases (from 2021 and 2023) related to lifted sidewalk tree roots, and one construction noise complaint from August 2023 that has been transferred to the appropriate department for tracking and resolution.
