260 Carl St, San Francisco, CA 94117

260 Carl Street is a 7-unit, 3-story multi-family residential building constructed in 1904, currently owned by Nantucket Ventures LLC. The building has undergone several significant safety and infrastructure upgrades in recent years, most notably a fire alarm system upgrade in March 2023 and electrical panel replacement in 2024 to meet current safety standards. The property completed mandatory soft-story retrofitting in 2017, demonstrating compliance with seismic safety requirements.

Historical maintenance records show attention to critical systems, including boiler replacements in 2013 and 2024, though there have been past issues with heating systems, including a documented boiler explosion in 2000 and a period of no heat and hot water in the same year. The building has experienced various maintenance and compliance challenges over its history, with multiple building violations in 2000 related to heating, hot water, and fire safety systems, all of which were abated by February 2000. A tree-related safety concern regarding fire escape access was reported in 2021, though no violations were recorded.

The property underwent significant electrical system improvements in 2023-2024, including the installation of low-frequency sounders in sleeping areas and replacement of Federal Pacific electrical panels. Recent complaints have primarily focused on permit compliance issues, with the most recent being a boiler permit renewal matter in early 2024, which was subsequently resolved by July 2024. The building's location has seen occasional municipal service calls, primarily related to sidewalk parking violations and street cleaning matters, though these are external to the building's operation and management.
