900 Powell St, San Francisco, CA 94108

The 14-unit, 3-story multi-family residential building at 900 Powell Street in Nob Hill, constructed in 1909, has undergone several significant improvements and encountered various compliance issues over its history. Most recently, in 2021, the building received a fire alarm system upgrade to meet San Francisco Fire Code requirements, including new detectors and notification devices. The property has experienced recurring fire alarm system challenges, with violations recorded in 2019 and 2021, though these were subsequently corrected.

A notable recent mechanical update occurred in 2022 with the removal of a hydronic boiler system, and in 2016, the building transitioned from a commercial water heater to multiple residential units. The building has undergone various major improvements over the years, including a substantial $750,000 kitchen and bathroom remodel in 2000, and an attempted unit legalization project in 2019. Historical records show a series of building violations from 2005 related to fire safety, plumbing, and security, all of which were abated by August 2005.

The property has maintained active compliance with building codes since then, with periodic inspections and necessary updates. Recent 311 calls from 2024-2025 have mainly concerned street-level issues such as garbage overflow and sidewalk conditions, which are municipal rather than building-specific concerns. The building's history includes multiple fire alarm system-related incidents, though none resulted in civilian injuries or significant damage. The most recent fire complaints in 2023 and 2021 were resolved promptly, indicating responsive maintenance of safety systems.
