What happens if I do not keep a construction diary?

Without documentation, you risk losing delay claims, being unable to prove completed work for invoicing, and facing liability for undetected defects. In court proceedings, the party with better documentation almost always has the advantage.

Does BGB §650n apply to private residential construction?

Yes. BGB §650n applies to all construction contracts under German law, including private residential projects. The client (Besteller) can request documentation at any time, and the contractor must provide it in text form.
