1117-1121 Guerrero St, San Francisco, CA 94110

The three-story, six-unit multi-family residential building at 1117-1121 Guerrero Street in Noe Valley, constructed in 1906, is currently undergoing significant modernization and safety improvements. Most notably, the building is in the process of installing new gas furnaces and updating lighting systems across multiple units (Units 2, 3, 5, and 6) between September and November 2024, with associated electrical and plumbing work permitted at costs ranging from $10,000 to $15,982. A significant fire safety upgrade was initiated in October 2024 to install low-frequency sounders in sleeping areas to comply with current fire code requirements.

The building has experienced several maintenance and safety-related issues over the years. An active complaint from October 2018 remains unresolved, citing multiple fire safety and smoke detection violations, including the need for automatic fire sprinklers over garbage receptacles, repairs to the central alarm system, carbon monoxide and smoke alarm compliance, and a gas meter instruction diagram posting requirement. The property has also undergone substantial unit renovations in 2024, including comprehensive rehabilitation of kitchens and bathrooms in Units 1, 2, 5, and 6, along with various electrical system upgrades including replacement of all residential sub-panels and improvements to smoke detectors and alarms.

A recent heating-related complaint was filed in December 2023, though it is noted as "Not Active." Historical records show the building has faced various challenges, including past issues with plumbing, improper storage of flammable materials (2010), inadequate heating systems (2011), and a back fence structural issue (2018). However, the property has completed important seismic safety improvements as evidenced by its Tier 3 soft-story compliance status. Recent 311 calls regarding the property mainly relate to external maintenance matters such as tree damage and general cleaning of public areas, which have been resolved through appropriate city departments.
