What is All-in rent?

All-in rent is a contractual agreement in which rent and certain ancillary costs are combined as a lump sum. Legally, much depends on the specific wording of the rental contract; the relevant rules on tenancy law can be found in the BGB.[1]

In most cases, the exact wording of the contract determines who is responsible for billing.

Move-in checklist

  • Review the rental contract: identify flat fees (payment) and all-in clauses.
  • Request and review operating cost evidence (evidence).
  • Note heating and water meter readings (heating).
  • Create a handover protocol and take photos of defects (evidence).
  • Clarify deposit, payment dates and due dates (payment).
Keep all receipts and photos well organized.

Adjusting flat fees

Whether you can adjust flat fees depends on the wording and legal provisions. For the distinction of individual operating costs, the Operating Costs Ordinance and the Heating Costs Ordinance are relevant.[2][3]

  • Observe objection deadlines (within days) and respond promptly.
  • Request renegotiation in writing and document all claims (form).

If there is a dispute

In case of unclear statements or unilateral claims, tenants can object and, if necessary, seek judicial clarification. Rental disputes are usually heard in the competent local court (Amtsgericht) in the first instance; higher instances are the regional court (Landgericht) and possibly the Federal Court of Justice.[4][5]

Respond to court mail on time to avoid losing rights.
