A property owner received a notice from the Urban Land Ceiling (ULC) office claiming their residential building, purchased in 1972 and occupied since 1983, is on surplus land and constitutes unauthorised occupation. Despite all approvals and tax payments, the owner was asked to regularise the 'occupation' by paying a fee. The owner is seeking advice on whether the ULC Act is still applicable and what actions to take, especially after receiving a second, incorrectly addressed notice.
