191-193 Cook St, San Francisco, CA 94118

The 1918 two-unit residential building at 191-193 Cook Street in the Lone Mountain neighborhood, owned by William C. Davis and Benjamin, has a mixed maintenance history with several significant events. Most notably, the property experienced multiple code violation issues between 2000-2005, including unauthorized window replacements, unpermitted laundry and water heater installations, improper waste lines, and an unauthorized two-story deck installation at the rear of the property - the latter requiring a $20,000 correction in 2007 to achieve compliance.

These violations were eventually resolved by 2009 through various completed building permits, including window replacements and stucco repairs. The building's systems underwent substantial work in 2009, including gas line extensions, laundry facility relocations, and water heater flue pipe installations, all of which were properly permitted. Historical maintenance records show earlier work including roofing (1999), dry rot repairs (1999), and various interior improvements.

More recent history (2019-2024) shows some infrastructure issues, including a sewage backup incident in 2020 and multiple cases of garbage and debris removal requests in 2024, though these are more reflective of general property upkeep rather than systemic building issues. The property has also been the subject of several 311 calls regarding various external matters, including illegal postings and graffiti (2017-2020), and parking-related complaints (2024). While the building experienced several significant code violations in its history, these appear to have been addressed through proper remediation and permitting processes, with no active violations on record as of October 2023.
