Who Pays for Alternative Accommodation?

Every apartment in our building will be affected by major remedial building work which will begin shortly.  Most of the work is for waterproofing and fire safety.   When we began our home owner’s warranty claim more than 10 years ago for this work, we were told that all costs would be covered in the payout.  The EC are now saying that owners have to pay their own costs for their alternative accommodation and storage when they are required to vacate their apartment for the builders.  And apartments with large outdoor areas will have to pay for all their plants and outdoor furniture to be removed and stored as well.

Who is liable for alternative accommodation costs during remedial building?
