Comparables: Tenants' Rights in Germany

Rent & Rent Control 2 min read · published September 07, 2025

What are comparables and when do they count?

Comparables are apartments used for reference in rent questions or when reviewing a rent increase. In practice, courts and authorities check whether apartments are sufficiently comparable in location, size, equipment and year of construction. As an existing tenant in Germany you should understand which criteria are common and which documents strengthen your position. Some disputes end at the local court, others reach higher instances; the relevant legal bases are found in the BGB.[1]

In most cases the specific fittings determine comparability.

Which documents help tenants?

Collect evidence that documents location, size and equipment systematically. Useful are floor plans, photos, energy certificate details, older rental contracts and current listings for comparable apartments. Clearly explain why a proposed comparable is not suitable (e.g., different heating system or missing balcony).

  • Floor plan and official living area statements.
  • Photos of condition, sanitary facilities and heating.
  • Printouts of current market offers for price checking.
  • Previous rental agreements as proof of prior rent.
Detailed documentation increases your chances in a legal dispute.

How to submit evidence correctly and observe deadlines

If you object to a rent increase or the set of comparables, respond in writing and within the deadline. Describe the defects in the selection of comparables, attach clear evidence and request a comprehensible calculation. In court proceedings the rules of the Code of Civil Procedure apply; if in doubt, seek legal advice.

Respond within set deadlines, otherwise you may lose rights.

Practical steps for tenants

  1. Review the presented comparables and note differences.
  2. Create an evidence folder with photos, floor plan and market offers.
  3. Send a brief letter to the landlord with copies of the evidence.
  4. If necessary, prepare a claim or objection and observe the ZPO deadlines.[3]
