4521 17th St, San Francisco, CA 94114

The 36-unit multi-family residential building at 4521 17th Street in Corona Heights, owned by Kitt Family Ltd Partnership, has undergone several significant safety and infrastructure improvements since its construction in 1958. Most notably, the building completed a mandatory soft-story retrofit in 2018 (with a cost of $400,000) to enhance seismic safety. Recent major works include the installation of a new fire alarm system (2024) costing $120,000 to bring the building into compliance with current fire code requirements, as well as a reroofing project (2024) costing $65,000 and the replacement of the building's boiler (2023).

The property has maintained an active maintenance schedule, with recent attention to deck repairs, including work completed in 2021 on units 24 and 26, and historical issues with dry rot being addressed through various permits between 2016-2021. The building has experienced some historical maintenance challenges, including multiple violations in 2000 related to mold/mildew, water damage, and security concerns, though these were all abated by September 2000. More recent complaints from 2022 regarding bathroom fixtures indicate occasional maintenance delays.

The property has received regular routine inspections, with some notable incidents including a 2016 rockslide that required slope stabilization work and a 2006 complaint about unsafe building conditions that was resolved by 2012. Fire safety systems have required ongoing attention, with several violations and complaints recorded between 2016-2024 regarding alarms and extinguishers, though most have been promptly corrected. The building's infrastructure improvements, including the recent fire system upgrade and soft-story retrofit completion, suggest a commitment to maintaining safety standards, though the open violation from November 2023 regarding sleeping area requirements remains outstanding.
