786 Vienna St, San Francisco, CA 94112

The property at 786 Vienna Street is a two-unit, two-story multi-family residential building located in San Francisco's Excelsior neighborhood. Built in 1908 and owned by Hermes Monzon Ruiz, this flats and duplex-style building has an extensive record of maintenance and safety issues, particularly related to fire safety systems.

The building has experienced multiple fire code violations over the years, with the most recent citations issued in November 2024 and November 2023 specifically concerning sprinkler system maintenance. Other documented violations include issues with the alarm system (October 2021) and blocked exits (January 2012). A cluster of complaints regarding garbage and debris has emerged recently, with multiple reports in December 2024 and January 2025, all of which have been resolved.

There was one significant complaint about unauthorized construction at the rear of the property in August 2021, though this was quickly addressed within three weeks. The building's earlier history includes termite and dry rot remediation work permitted in 1991, though this permit is now expired. While the property has had various fire safety issues documented through both complaints and violations, it's noted that no civilian injuries have been reported from any fire-related incidents, which have been limited to contained cooking fires and malfunctioning smoke detectors.
