531-533 Natoma St, San Francisco, CA 94103

The two-story, four-unit multi-family residential building at 531-533 Natoma Street in San Francisco's South of Market neighborhood has a recorded history of maintenance and safety compliance efforts dating back to 1991. Recent activity includes the issuance of a plumbing permit in March 2024 for the replacement of a 40-gallon gas water heater.

The building has undergone several significant structural and safety-related improvements over the years, including stair repairs and replacements in 1993 (with associated handrail work), reroofing in 1991, and multiple health and safety inspections by Housing Inspection Services in 2004, 2008, and 2012. A notable cluster of building violations was recorded in January 2004, addressing stair safety issues including handrail and guardrail requirements, gas utility shutoff tool requirements, and security concerns, all of which were abated by February 2004. The property has experienced recurring fire safety system inspections and issues, with the most recent fire complaint in September 2023 regarding sprinkler/standpipe systems (which was corrected promptly), and multiple fire system-related complaints in 2022 including concerns about alarms and extinguishers that were also corrected.

Historical fire violations from June 2017 regarding sprinkler and extinguisher requirements were eventually abated. The building underwent a significant routine safety inspection in 2008 that identified various compliance issues, and more recent inspections have continued to monitor fire safety systems. The surrounding area has generated multiple 311 calls in recent months (2024-2025), primarily related to garbage and debris on public areas near the building, though these external issues do not directly reflect on the building's internal conditions or management.
