Yes, that would then allow for the work to take place, but they are then liable for all costs incurred. Leaks can be notoriously difficult to track down, and expensive to repair. Introduce the height involved in most apartment complexes and that brings the extra expense of scaffolding, hoists, etc. into it. The investigation phase alone could run into thousands, the repairs, 10s of thousands.
They would also need to be very careful that the agreement with the MC dosen't end up with them being responsible for any ongoing or future issues in that area. I'd strongly recommend seeking legal advice before going down that road.
