Building authority orders, open notices and official conditions should be checked before signing a property purchase contract. The key question is whether the buyer would take over measures, costs or deadlines after acquisition.
The review must compare building file, permits, occupancy documents, plans, correspondence on conditions and land register. If these sources do not match, a general clause in the contract will often not solve the problem later.
The focus is not on planning a construction project, but on securing an existing official finding before the purchase contract. The decisive basis remains the specific contract, the current land register situation and the applicable Austrian legal framework.
