820 Jones St, San Francisco, CA 94109

The 6-story, 24-unit apartment building at 820 Jones Street in Downtown, constructed in 1924, has undergone several significant safety system upgrades in recent years, most notably a substantial fire system enhancement completed in July 2023 costing over $25,000, which included installing new low-frequency horns in all units and upgrading the power supply panel. A concerning issue remains active from June 2022 regarding a suspected below-grade sewer failure potentially affecting neighboring basements, though this complaint hasn't been marked as resolved.

The building's electrical infrastructure is currently undergoing improvements, with multiple permits filed between April and June 2024 for installing 60-amp sub panels in various units, and additional fire system modifications. The property has a history of various violations and safety-related incidents, with multiple fire safety system inspections showing recurring issues that have generally been resolved promptly. Historical complaints from 2001-2010 indicated problems such as inadequate heating, expired hallway fire extinguishers, and a rusty fire escape ladder, though these were addressed.

More recent 311 calls (September 2024 - January 2025) indicate ongoing concerns with street cleanliness and maintenance in the vicinity, particularly regarding debris. The building has experienced typical urban issues such as garbage and debris complaints, though these are more related to street conditions than building maintenance. The most significant fire incident on record was a building fire with intentional ignition, though fortunately resulting in no civilian injuries.
