1489-1493 Guerrero St, San Francisco, CA 94110

The three-story multi-family residential building at 1489-1493 Guerrero Street in Bernal Heights, owned by Sophia Lo, was constructed in 1906 and contains three units. The property has experienced several significant maintenance and safety issues over the past decade, with the most pressing recent concerns occurring in 2016 when multiple building violations were recorded regarding heating system failures and a defective heater. These violations included notices for repairs and system deficiencies, with a notable complaint from March 2016 concerning complete lack of heat that affected a disabled tenant.

Earlier issues from 2013-2014 involved water intrusion problems, plumbing leaks, pest control concerns, broken windows, and window repair disputes, though most of these complaints were eventually marked as not active. Multiple fire safety violations were documented in 2010, including issues with garbage receptacle placement, combustible storage, building attachments, door security, and fire extinguisher requirements, indicating historical non-compliance with safety standards. The building's maintenance history shows some attempted upgrades, such as the replacement of a Williams heater in 2016, though records indicate this permit has expired.

More recent permits show minimal activity, with only one street space permit issued in 2020. While there was one documented incident of carbon monoxide detector activation (without any confirmed CO presence), it was not related to any building system failure. The immediate vicinity of the property has experienced typical urban challenges as evidenced by recent 311 calls in 2024, including reports of encampments, offensive graffiti, and street cleaning issues, though these are external to the building itself. A routine inspection was conducted in 2010 following complaints from the adjacent address (1487 Guerrero Street), and historical records show some sidewalk maintenance issues were addressed in 2010 regarding tree root damage to the walkway.
