Everything you need to know about defect notification before acceptance/handover (Mängelanzeige)

What is a notice of defects (Mängelanzeige)?

A notice of defects is a legal step taken by the buyer or owner to inform the contractor or seller about defects discovered in the building or finishing works before the formal acceptance of the works (Abnahme).

The purpose of this notice is to require the contractor to remedy the defects before final handover, thereby protecting the buyer from future repair costs.

When is a notice of defects submitted?

• It is usually submitted during or immediately after the final inspection of the property, i.e. before signing the formal acceptance document.

• If the acceptance is signed without any reservations or comments, the owner is deemed to have agreed to the condition of the property. In that case, proving and enforcing defect claims later on becomes much more difficult.

Examples of common defects

• Cracks in walls or ceilings.

• Water leaks, damp patches or inadequate insulation.

• Defective electrical or plumbing installations.

• Uneven or poorly laid floors or tiles.

• Problems with windows and doors, such as poor closing or misalignment.

How should a notice of defects be submitted?

• Always in writing: In order to document the situation formally and in a legally robust way (e.g. by registered mail or e-mail with confirmation of receipt).

• With a precise description: Clearly specify the defect, its exact location and its impact (for example visible damage, functional problems).

• Supported by photos: Photographs or videos provide visual evidence of the type and extent of the defect.

• With a deadline for rectification: A reasonable period for the contractor to remedy the defects should be set.

What happens after the notice is submitted?

• The contractor or seller is obliged to remedy the notified defects within the specified period.

• If the contractor ignores the notice or refuses to carry out repairs, the owner may, under certain legal conditions:

  • withhold part of the payment,

  • appoint another company to carry out the repairs and charge the costs to the original contractor (after proper notice),

  • in serious cases, withdraw from the contract or claim damages in accordance with the German Civil Code (BGB).

Relationship between the notice of defects and the warranty period

Even after acceptance, the owner is protected by a statutory warranty period, which for buildings is usually five years under the German Civil Code (BGB).

However, recording and reporting defects before formal acceptance has major advantages:

• Many issues can be remedied while construction is still ongoing.

• Disputes can often be avoided because the defect is clearly documented before the property is officially taken over.

Important tips before handover

• Take a building expert or architect with you to the final inspection if possible.

• Record all observations – large and small – in writing, even if they seem insignificant at first glance.

• Do not rush into signing the acceptance protocol. Take time to make sure you are truly satisfied with the condition of the property.

• Keep a copy of the notice of defects and all written correspondence with the contractor.

Risks of ignoring a notice of defects

• Loss or significant restriction of the right to free rectification of defects.

• Having to bear the costs of repairing defects yourself at a later date.

• A lower resale value of the property because of unresolved defects.

Conclusion

In Germany, submitting a notice of defects before acceptance is a key legal step to protect your investment and to ensure the quality of the property you are about to own. Careful inspection, thorough documentation and prudent action help you avoid future problems and unexpected costs – and allow you to enjoy your new home with confidence and peace of mind.
