Your case is not for declaratory relief. It is a claim for breach of the covenant of quiet enjoyment and implied covenant of good faith. Damages are for the interference with your reasonable business expectations by the landlord which prevents you from enjoying the benefit of the bargain. Any consequential damages associated with your having to relocate may be recovered.
However, in a settlement negotiation, what you get is what you agree to. You may find that the landlord treats your demand for consequential damages as a deal breaker. If you do, then you will have to decide whether to sue and risk the court not giving you attorney's fees as part of the suit, or accepting something less than what you originally wanted.
The point is that a settlement is a negotiation,and unless you're prepared to negotiate, you'll probably find it a waste of time.
Hope this helps.
