370 Bartlett St, San Francisco, CA 94110

370 Bartlett Street is a two-story, four-unit multi-family residential building located in San Francisco's Inner Mission neighborhood, built in 1960 and currently owned by Hector Omar Chavez. The property has undergone several significant changes and faced numerous compliance issues over the years. Most recently, in October 2020, there was a filing for voluntary strengthening work to comply with the 2013 San Francisco Building Code.

There are active concerns regarding the building's condition, particularly relating to an in-law unit at the rear of the building, with complaints about roof leaks, structural concerns about an allegedly weak patio, and multiple unpermitted modifications noted in 2016 that remain unresolved. The building's history includes attempts to legalize additional units, with a cancelled permit in 2017 for a street-level unit addition and a cancelled permit in 2018 for rear level unit legalization, though planning records show previous efforts to address this issue with various outcomes. The property has a documented history of maintenance and safety concerns, particularly during the early 2000s and mid-2010s. Building violations from 2016 cited the property as a nuisance under section "1001-d" of the San Francisco Housing Code, noting various issues including unapproved modifications, missing required fire-resistant materials, and lack of smoke detectors.

A routine inspection in 2007 identified multiple safety concerns, including problems with stairs, fire door requirements, and fire extinguisher maintenance. Earlier complaints from the 1990s documented issues with heating systems, plumbing, and general maintenance. Recent building permits show some positive maintenance activity, such as kitchen and bathroom renovations in 2017 and window upgrades in 2012, though some permits were cancelled rather than completed. The building's location has experienced typical urban challenges as evidenced by multiple 311 calls in 2023-2025 regarding street conditions, though these relate more to exterior environment issues rather than building-specific problems.
