3939 20th St, San Francisco, CA 94114

The 10-unit, 2-story multi-family residential building at 3939 20th Street, owned by Swig Louise and constructed in 1959, has undergone several significant improvements and faced multiple challenges over its history. Most notably, the building completed a mandatory soft-story seismic upgrade in 2014 at a cost of $60,000, achieving Tier 3 status with Certificate of Final Completion (CFC) issued.

Recent maintenance work includes a reroofing project completed in 2017, although this work initially generated complaints about unpermitted construction and dust issues from neighbors. The building has experienced periodic maintenance and safety inspections, with the most recent complaint filed in December 2022 addressing multiple issues such as peeling paint, improper storage, and various building code violations, which were subsequently abated by March 2023. Fire safety has been a recurring focus, with recent inspections in 2024 and 2022 noting issues with fire extinguishers and alarm systems respectively, though both were promptly corrected.

Historical records show various maintenance activities including termite work in 1991, pest damage repair, and the installation of a steel roof fence in 2004 to prevent roof access. The property has faced occasional enforcement actions, including multiple building violations in 2004 related to fire safety and emergency preparedness, all of which were abated. Recent 311 calls suggest ongoing attention to external conditions, with reports of sidewalk defects, graffiti, and hazardous materials being addressed by city departments over the past three years.
