Myself and 3 other owners have already lost 3.5 months of rent due to these works and possibly another month at least before we can rent our apartments out again. What is my recourse here for both financial losses?
Send the owners corp a bill for the lost rent. When they refuse to pay it, take them to your local court. It’s simply not fair that a minority of owners should suffer financially to benefit everyone.
