999 Fell St, San Francisco, CA 94117

The 3-story, 9-unit apartment building at 999 Fell Street in Hayes Valley, owned by Plaza Group LLC, has undergone several significant improvements and faced various maintenance challenges since its construction in 1907. Most notably, the building completed mandatory soft-story seismic retrofitting in 2017 (as a Tier 3 building), demonstrating compliance with seismic safety requirements.

Recent unit improvements include a $30,000 kitchen and bathroom remodel in Unit #6 completed in 2022, and similar renovations in Units #5 and #9 in 2015-2016, which included comprehensive updates to plumbing, electrical systems, and interior finishes. The building has experienced recurring issues with its fire safety systems, including multiple fire alarm system violations between 2005 and 2020, though these were generally promptly addressed. A concerning pattern emerged in February 2021 with complaints from Unit #6 regarding mold, leaking ceilings, and electrical/plumbing issues, though these complaints were eventually marked as not active.

The property underwent a unit legalization process in 2019 to comply with local regulations, and more recently, there have been several 311 calls (in early 2025) regarding graffiti and debris outside the building, though these were primarily external issues not directly related to building operations. The building has maintained regular safety inspections, with no ongoing violations currently recorded. While historical violations and complaints suggest periodic maintenance challenges, the completion of major infrastructure improvements like the soft-story retrofit and recent unit renovations indicate proactive building management in addressing building code requirements and improving resident amenities.
