A homeowner who sued the builder of her mansion near Stuart can litigate her claims of shoddy construction after an appeals court said she isn’t bound to arbitration.

Jennifer Billings in May 2016 paid nearly $1.5 million for her three-bedroom, 3,800-square-foot house with a pool on the exclusive Sailfish Point, a peninsula on the Atlantic Ocean and St. Lucie Inlet. She moved in with her children only to discover water intrusion, mold and fecal-related bacteria on some building materials, according to an environmental consultant she hired.
