Alternative Housing & Offer Duty: Tenants in Germany

Special Termination Protections 3 min read · published September 07, 2025

As a tenant in Germany, you often face decisions about alternative housing, proofs and the so-called offer duty of the landlord. This guide provides practical tools, templates and a step‑by‑step checklist so you can document medical notes, forms and deadlines correctly. I explain in plain language which proofs a landlord may require, how to evidence an alternative dwelling and when administrative steps or a visit to the local court may become necessary. The guidance follows the BGB and current procedural rules, is written specifically for tenants and aims to help you act legally and transparently, avoid conflicts and assert your rights in tenancy law.

What does the offer duty and alternative housing mean?

The offer duty describes situations where a landlord must provide alternative housing or otherwise ensure replacement, for example when an apartment is uninhabitable or during necessary modernizations. Legal foundations are in the Civil Code (BGB), especially regarding landlord duties and tenant rights.[1]

The key rules for tenancy law are found in §§ 535–580a of the BGB.

Important proofs and evidence

If you want to prove an alternative housing claim or entitlement to replacement, clear, dated evidence is crucial.

  • Medical notes (doctor certificates) as proof for health reasons.
  • Forms and written offers for alternative housing from the landlord.
  • Photos and protocols of defects, measurements and appointments.
  • Deadlines, cure notices and delivery receipts for submissions.
  • Correspondence with authorities or courts in escalated disputes.
Keep all documents and appointments in chronological order.

Forms, templates and practical procedure

For many steps there are official or established templates: for example termination letters, objections or damage reports. As a practical example, a standard termination letter is often used as orientation (template sources are available on official ministry sites).[2] Complete forms fully, attach medical notes as PDFs or copies and document delivery or dispatch by registered mail.

  • Termination letter (template) – use only if termination is actually intended.
  • Medical certificates – clearly state the restriction and issue date.
  • Handover protocol – note date, time, participants and observed defects.
Respond within the set deadlines or claims may lapse.

If the dispute goes to court

If an out-of-court solution fails, local courts (Amtsgerichte) are the first instance for tenancy disputes in Germany; higher courts and the Federal Court of Justice (BGH) may decide on legal questions. Inform yourself early about filing deadlines and procedures, and consider legal insurance or advice.[3]

Detailed documentation increases your chances in legal disputes.
