Notifying Changes: Tenants' Guide in Germany

Housing Allowance & Rent Subsidies 3 min read · published September 07, 2025

As a tenant in Germany, you must notify changes such as address moves, household composition, or receipt of housing allowance in a timely and correct manner to the landlord and, if applicable, the authority. Mistakes in wording, missed deadlines, or unclear evidence can lead to misunderstandings, denied subsidies, or even legal action. This article explains which details matter, which official forms exist, how to meet deadlines and which proofs are useful. You will also find practical sample wordings for letters to the landlord and guidance on when a local court may need to be involved. The aim is to empower you as a tenant, avoid typical mistakes and clearly understand your rights in Germany.

What Tenants Must Report

Many obligations arise from the rental contract and legal requirements; the Civil Code (BGB) governs central points regarding tenant duties and obligations.[1]

Detailed documentation increases your chances of success.
  • Address change: Inform the landlord and, if applicable, the registration authority within the usual deadlines.
  • Change in household composition: Report births, departures or new roommates to the landlord.
  • Receipt or loss of housing allowance or subsidies: Submit applications and proof to the responsible office.[2]
  • Damages and defects: Report defects immediately in writing, document photos and timestamps.
  • Subletting and changes of use: Always obtain the landlord's written consent.

Forms and Templates

Important forms for tenants include the local housing allowance application (at the city or municipality), written termination templates and standard notifications to the landlord. Many applications are provided by the municipality; for legal bases see the BGB and the Housing Promotion Act.[1][2]

  • Housing allowance application (municipal form): Used to apply for housing allowance or to report changes in receipt; example: if you suddenly receive short-time work benefits, notify the changed income status via application.
  • Termination letter (tenant template): Terminate in writing with date, address and signature; example: to move out on time, name the last day of the tenancy in the letter.
  • Defect notification: Briefly state the defect, time of discovery and desired deadline for remedy; attach photos as evidence.
Respond to official letters within stated deadlines to preserve your rights.

Deadlines, Proofs and Practical Steps

Deadlines vary: registration obligations to the municipality follow different rules than notifications to the landlord. Note deadlines in a calendar, send important letters by registered mail and keep copies.

  • Meet deadlines: Record deadlines in writing, send changes verifiably (registered mail or electronic receipt) for important matters.
  • Collect proofs: Pay slips, housing allowance notices, photos of defects and the rental contract should be organized.
  • Document communication: Note date, content and, if applicable, witnesses.
Keep all receipts and photos for at least the duration of the tenancy.

Legal Steps and Courts

In disputes, a conversation and a written reminder are often the first steps. If that does not help, the local court (Amtsgericht) can be competent as first instance for tenancy disputes; higher instances like the regional court or the Federal Court of Justice decide on appeals or precedent cases.[3][4]

Frequently Asked Questions

Which changes must I notify my landlord immediately?
Any change affecting the contractual relationship, such as address change, subletting, new roommates or significant income changes, should be reported promptly.
How do I submit a housing allowance change notice?
Use the local housing allowance office and submit current proofs (income, household size); many municipalities provide a specific form.
What if the landlord does not respond?
Send a formal reminder, document deadlines and consider legal steps; in case of acute defects, rent reduction may be an option if conditions are met.

How-To

  2. Step 2: Draft a short, factual letter to the landlord with date, facts and requested deadline.
  3. Step 3: Send the letter with proof of delivery (registered mail or email with receipt) and keep copies.
