Reporting Changes: Avoid Mistakes for Tenants in Germany

Housing Allowance & Rent Subsidies 3 min read · published September 07, 2025
Many tenants in Germany need to report changes to their tenancy, such as address changes, household composition changes, income changes for housing allowance, or consents for modernizations. Mistakes when notifying can lead to misunderstandings, delayed housing allowance payments, or legal problems. This guide explains in plain language which details you must provide correctly, which deadlines apply and how to document formal letters and evidence securely. It gives practical wording examples, points to official forms and outlines which courts handle housing disputes. This helps tenants keep track of their rights and duties and avoid common mistakes that cost time and money. The guidance is based on German tenancy law and cites relevant statutes and official contact points for assistance.

What to check first

First check whether the change must be reported under your lease (for example for subletting, household changes or income changes for housing allowance). If in doubt consult the lease and the statutory provisions of the BGB[1]. Note applicable deadlines and request written confirmation from the landlord where possible.

Keep copies of all letters and evidence in a safe place.

Key steps when reporting changes

  • Fill out forms and letters carefully and include the date.
  • Respect deadlines stated in the lease and statutory deadlines.
  • Collect receipts, photos and emails and file them chronologically.
  • Send important notifications by registered mail or deliver in person with a receipt.

For financial changes like housing allowance, verify eligibility and gather income documents to avoid interruptions in payments.

Clear documentation reduces the risk of later disputes.

For major changes (e.g. long-term subletting or structural changes) the landlord's consent is often required; obtain written approvals. In case of disputes in Germany local courts (Amtsgericht) are competent initially, then regional courts (Landgericht) or the Federal Court of Justice (BGH) for appeals[3].

Forms and templates (when to use them)

The following forms are relevant for tenants:

  • Notice of termination / template termination letter: Used when you want to end the tenancy; example: a signed written notice specifying the termination date.
  • Housing allowance application: Submit to the responsible housing allowance office when your income or household size changes and a continued benefit is needed.
  • Defect report: Inform the landlord in writing with date, description of the defect and request its remedy; attach photos.

For court proceedings, claims are filed according to the Civil Procedure Rules (ZPO)[2]. Seek advice before filing a lawsuit or check the claim procedure at your local court.

Common mistakes and how to avoid them

  • Undocumented agreements: insist on written confirmation.
  • Missing deadlines: record response and objection deadlines.
  • Incomplete evidence: always include copies of invoices, photos and emails.
Respond promptly to termination notices and official letters to preserve your rights.

FAQ

When must I inform my landlord of an address change?
You should inform your landlord immediately so that legal notifications can be delivered effectively.
Can I sublet without consent?
Often not; permanent subletting usually requires the landlord's consent. Check your lease and obtain written permission if unsure.
What if the landlord does not react to my defect report?
Set a reasonable deadline in writing and document everything; if the landlord remains inactive you may consider rent reduction or legal action.

How-To

  1. Collect documents: tenancy agreement, current notices, photos and emails.
  2. Notify in writing: state the change clearly, add the date and your signature.
  3. Observe deadlines: send notifications in time and follow up on responses.

Key Takeaways

  • Written documentation is often decisive in tenancy disputes.
