Fenland District Council is considering prosecuting the owners of Constantine House in Wisbech as repair work has still not been completed.
The Nene Quay building had become an eyesore in the town after being damaged by fire in 2010.
The council had served a notice on the owners to complete necessary works by Monday, October 26, but an inspection earlier this week has found this has not been done.
A council statement says; “The owners of Constantine House in Wisbech have not complied with the Section 215 Notice requiring them to complete the necessary works by Monday, October 26, 2015, and they did not exercise their right to appeal the notice.
“An enforcement officer inspected the site on Monday. He reported that no further work had been done there since August. Consequently, the matter is now with our legal team to review, with a view to prosecution.”
