3719-3721 Market St, San Francisco, CA 94131

The property at 3719-3721 Market Street in Noe Valley is a 2-story, 3-unit multi-family residential building constructed in 1958, currently owned by the Jjt Family Trust. The building has faced significant code compliance issues, with persistent active violations dating back to December 2017, including concerns about unapproved unit conversions, safety equipment, and fire separation between units.

These violations were documented during inspections identifying multiple code infractions such as unauthorized wiring and plumbing modifications, lack of approved heating systems in living spaces, and concerns about occupancy violations. The building underwent several repairs in recent years, including a corrected code violation regarding dryer vents in 2019, replacement of vinyl siding and moisture barrier in response to complaints, and re-roofing work completed in 2015.

Between 2022 and 2025, there have been multiple maintenance issues logged through 311 calls, including two sewer-related incidents (including one sewage backup in December 2023), flooding, and sidewalk concerns, though most were resolved through appropriate city interventions. A cluster of fire safety-related violations from 2017, including missing fire extinguishers and smoke/CO alarm issues, were addressed through permits, though at the time of this report, two complaints from 2017 regarding fire safety and unit conversion violations remained active with a director hearing scheduled in October 2019. The building's documented history includes a cooking-related fire incident, though no civilian injuries were reported.
