A local restaurant is suing its former landlord due to significant mold buildup in the premises that should have been remediated following Hurricane Katrina. CS X 2 LLC filed suit against Metairie Properties LLC, United Fire & Casualty Company and Liberty Mutual Insurance Company in the 24th Judicial District Court on Sept. 18. In 2005 CS X 2 LLC, the owner of restaurant Chad’s Bistro, asserts it executed a lease on a commercial building located at 3216 West Esplanade Ave. in Metairie owned by Metairie Properties and that shortly afterward Hurricane Katrina struck the area and inundated the building with around a foot of flood water.
