406-410 Broderick St, San Francisco, CA 94117

The three-story multi-family residential building at 406-410 Broderick Street, constructed in 1908, contains 6 units and has undergone several significant improvements over the years. Most notably, the building completed a required soft-story retrofit in 2016 (Tier 3) at a cost of $55,000, demonstrating compliance with seismic safety requirements. Recent maintenance work includes a sewer replacement in 2017, reroofing in 1996, and termite repairs in 1988.

The building has experienced multiple heating system issues in 2022-2023, with complaints from tenants about inadequate heat, old heaters, and poor communication regarding heating upgrades, culminating in a complaint about insufficient heating in Unit 408 in March 2023. Additionally, there were several building violations in 2021 related to interior surfaces, smoke detectors, and fire safety systems, though most were abated by late 2021. The property has had two fire-related incidents recorded, though neither resulted in civilian injuries, and a fire alarm system malfunction was corrected in 2007.

Recent external maintenance concerns include a December 2024 report of an overgrown tree blocking a traffic signal (currently open) and multiple graffiti complaints in late 2024. The building's management has faced scrutiny regarding potential short-term rental violations, with complaints suggesting unauthorized rentals through platforms like Airbnb, though this investigation was eventually marked as closed. The property is classified as rent-controlled, with records indicating that four of its six units may be operating as in-law units (ILOs).
