When a defect appears on a finished building, two routes are open that complement one another. The warranty under sections 922 to 933 of the Austrian Civil Code (ABGB) ensures that you receive the defect-free work you paid for. The damages claim under section 933a ABGB reaches further and also covers consequential losses, but for that it requires fault on the part of the contractor.

This calculator takes the date of handover and of discovery, your role and the type of problem. From this it follows whether the warranty period is still running and which route comes to the foreground in your case. The result is an initial assessment and does not replace an examination of the individual case.

This tool gives an initial, non-binding orientation on the Austrian legal position (legal status June 2026) and does not replace a lawyer’s examination of your individual case. The start of the period, fault and the evidence depend on the specific circumstances.

Note: This calculator is general guidance on the Austrian legal position (legal status June 2026) and does not replace advice in an individual case. Whether warranty or damages applies depends on fault, the start of the time limit and the evidence, which are often disputed in an individual case. For a binding assessment we recommend an initial consultation (72 euro).
