1160 Treat Ave, San Francisco, CA 94110

The property at 1160 Treat Avenue in the Inner Mission neighborhood, currently owned by Soberanis Orbelina, has a controversial history marked by unauthorized construction and multiple permit modifications. Built as a multi-family residential building with 2 dwellings on one parcel, the property experienced significant renovation activity between 2009-2011, with several permitted improvements including electrical upgrades, room expansions, and plumbing work.

Notably, a building violation was issued in July 2010 for unauthorized construction at the top floor, including roof modifications to create additional space, which was not resolved until May 2012 through a formal notice of violation process. Two additional complaints were filed in July 2010 regarding unpermitted structural changes, including alterations to the A-frame and unauthorized additions to the building's rear. More recent history (2024-2025) shows a pattern of waste management issues, with multiple 311 calls reporting abandoned furniture and debris on or near the property.

Between August 2024 and January 2025, there were at least eleven reports of garbage and debris, including instances of furniture and bagged garbage being left on the street or property, all of which were subsequently resolved by city services. The building underwent several permitted improvements during the 2009-2011 period, including electrical work (with some permits being cancelled and revised), installation of additional lighting and outlets, and modifications to increase usable living space. The property's records indicate it was constructed with 2 dwellings on one parcel, though the original construction year is not specified in the available data.
