Abnahme is the client's acceptance of completed construction work as essentially conforming to the contract — a legal act, not a ceremony. It starts the five-year limitation period for defect claims on a building, passes the risk to the client and can cost rights that are not reserved on the day.
• The date and signatory of the acceptance, and any deemed acceptance under § 640(2) BGB.
• Every known defect, and any contractual penalty, reserved in the protocol.
• The adviser's inspection report, ready before the acceptance date.
• The tenant's handover under the lease aligned with acceptance, so that defects the tenant lists can still be reserved against the developer.
• The expiry of the limitation period, with an inspection about six months before it (Part 7).
