1140 Potrero Ave, San Francisco, CA None

The property at 1140 Potrero Avenue is a two-story, three-unit multi-family residential building located in San Francisco's Inner Mission neighborhood, built in 1907 and owned by Thomas Pius & Breda Ann McDon. The building has undergone several significant modifications and faced various challenges over the years.

Most notably, substantial improvements were made between 2007-2011, including a one-story horizontal addition and a change of occupancy classification, with the installation of a comprehensive fire sprinkler system completed in 2011 costing $30,000. The building experienced multiple compliance issues with the Vacant or Abandoned Building Ordinance (194-09) between 2008-2012, though all violations were ultimately resolved. Historical maintenance issues included serious sewer problems, with documented incidents of sewage spillage onto public areas in 2002 and 2006, and concerns about the building's condition leading to a 2005 soundness investigation.

The property also faced several abandoned building complaints throughout the 2000s, with reports of unauthorized occupation and maintenance violations in 1998-2002. Recent structural concerns were noted in 2011 regarding safety issues with a third-floor front patio's access to a neighboring roof. While the building had a history of plumbing and occupancy-related violations, the completion of major renovations and safety improvements suggests significant infrastructure upgrades have been implemented to address past deficiencies.
