Bürgerliches Gesetzbuch
German rent regulation is found in the "Civil Code" (the "Bürgerliches Gesetzbuch") in § 535 to § 580a. As common in German law, regulations are structured into an abstract, more general part that applies to all contracts of a certain type, followed by a more specific section for individual fields of application of this type of contract. Specific regulations for rental contracts governing apartments range from §§ 549 - 577a BGB.
