The Mosers allege that the Clines failed to prove the fourth element — failure to restore the premises to habitability. They contend that the uncontroverted evidence shows that they did restore the premises to habitability after the sewer backed up and flooded the basement. The undisputed evidence revealed that the Clines called Mr. Moser on December 29, 2005, and notified him of a clogged sewer. He told them to put four bottles of liquid gel drano down the drain to fix the problem. The Clines called Mr. Moser back on January 11, 2006, and informed him that the fix did not work. Mr. Moser called a plumber that day. The plumber informed Mr. Moser that the sewer line might have collapsed or was badly clogged and that a new sewer line would need to be installed. The installation of a new sewer line would involve acquiring city permits to cut the street, which would cause at least a two-week delay. Mr. Moser testified that he determined that the repair would be better done if no one lived in the house; therefore, he notified the Clines of his intent to terminate the lease based on the house becoming untenantable as well as failure to pay rent. Ms. Cline testified that she was never told the lease was being terminated based on the untenantable condition of the property. She said she was told only that the Mosers wished to sell the property rather than make the expensive repair. Regardless, the repair, costing in excess of $5,000, was eventually made while the Clines continued to live in the house. The Clines did not dispute that the repair was made. Although the record is unclear when the repair was finally made, the Clines had the burden to prove that the landlord failed to remedy the problem within a reasonable amount of time. Thus, the Clines failed to prove their breach of warranty of habitability claim, and the trial court erred in finding for the Clines on the claim and in awarding damages for it by offsetting the Mosers’ damages in their rent and possession claim. 4
