104-114 Guerrero St, San Francisco, CA 94103

The four-story, 7-unit multi-family residential building at 104-114 Guerrero Street, constructed in 1906, has undergone significant renovations and faced multiple maintenance challenges in recent years. The most substantial work occurred from 2019-2020, when three new basement units (7, 8, and 9) were added, including a full electrical upgrade to 400 amp service, new fire sprinklers, and comprehensive plumbing work including bathroom and kitchen installations. The building faced serious heating system issues in late 2021 through 2023, with multiple complaints about inadequate heat and hot water, particularly during winter months.

These problems resulted in violations and required corrections, with the heating system being replaced in February 2023 to address these deficiencies. Recent improvements include the installation of mini-split heat pumps in July 2022 for Units A and B, and a new commercial gas water heater in February 2023. The building has a completed Soft Story retrofit (Tier 3) and has seen regular maintenance through various permits for street space use and other repairs.

While there have been multiple fire alarm system activations, carbon monoxide incidents, and a hazardous conditions call recorded by the fire department, none have resulted in civilian injuries. The most recent complaints in 2023 involved common areas and heating system issues, which were subsequently addressed. The building's management has demonstrated responsiveness to most maintenance requirements, though some issues have persisted intermittently, particularly regarding the heating system. A tenant buyout occurred in October 2018 for $32,946.75 involving two tenants at 108 Guerrero Street, indicating previous unit turnover activity.
