Completely unacceptable to not be allowed access and inspection prior to lease signing and would be cause to break lease in my humble opinion. If the contract is not signed then don't. For sure the building has wiring faults which may be dangerous and you / your family would be forced to fix them prior to opening for business. Ask solicitor if he'd like to stump up for the repairs bill and he might start to take an interest
