Void Clauses in Your Lease: § 536 Para. 4 BGB

Published on March 14, 2026

§ 536 Para. 4 BGB – Rent Reduction Cannot Be Excluded

Some lease agreements contain clauses that limit or entirely exclude the right to rent reduction. Under § 536 Para. 4 BGB, such agreements in residential tenancies are void. The law protects tenants from having to waive this important right.

Typical Void Clauses

The following wordings in lease agreements are legally unenforceable:

  • "The tenant waives the right to rent reduction" – Direct exclusion clauses are always void
  • "Rent reduction is only permitted with prior written consent of the landlord" – Rent reduction takes effect by operation of law and needs no approval
  • "The tenant shall remedy defects at their own expense" – When formulated broadly, this is void as it undermines the landlord's obligations
  • "Defects known to the tenant at move-in do not entitle them to a reduction" – Partially valid under § 536b BGB, but only if the tenant actually knew about the defect and did not reserve their rights

Why Are These Clauses Void?

§ 536 Para. 4 BGB is a so-called mandatory provision (ius cogens). In residential tenancies, it cannot be deviated from to the tenant's detriment. The legislator wanted to ensure that tenants are not put in a worse position through contract clauses.

What to Do If Your Contract Contains Such a Clause?

  1. Don't panic: The clause is automatically void – you don't need to take any action against it
  2. Don't be intimidated: Some landlords invoke such clauses even though they are void
  3. Document the defect: Proceed normally – report the defect, set a deadline, reduce rent if applicable
  4. Inform your landlord: Notify the landlord objectively that the clause is void under § 536 Para. 4 BGB

Exception: Commercial Leases

Important: § 536 Para. 4 BGB applies only to residential property. In commercial leases, the right to rent reduction can be contractually excluded or limited. If you rent commercial premises, review your contract carefully.

Tip: Read your lease carefully – but don't be unsettled by void clauses. When in doubt, a free initial consultation with a tenants' association can help.
