Tenants: Report Changes in Germany

If something changes with your rented home in Germany — for example your address, household composition, or income — you should notify the relevant parties promptly. For tenants this can affect the lease, utility cost settlement and support such as housing benefit or rent subsidies. This article explains in plain language which changes matter, which documents landlords or authorities typically require and which deadlines apply. I show practical steps for filling in forms, compiling proof and handing over documents securely. I also name the responsible courts and authorities, explain the most important sections of the BGB ^[1] and give examples of when a review or appeal deadline arises. Read on for checklists and sample letters.

When you should report changes

Not every change requires immediate written notice, but some have legal or financial consequences. Notify changes promptly when they affect rent payment, utility billing or benefit entitlements (housing benefit / rent subsidies).^[2]

• Notify the landlord (new internal address, fixed subletting, change in household size).
• Notify the property manager or housing company (bank details, move-ins/move-outs of subtenants).
• Meet deadlines for authorities when income rises or falls and housing benefit / subsidies are affected.
• Report changes affecting eligibility (e.g. housing entitlement certificate changes in household size).

Which documents to prepare

Prepare documents before making notifications or submitting forms. Clear, complete documentation speeds up reviews and reduces follow-up questions.

• Identity card or passport (document) for identification.
• Lease and last utility bill (document) as proof of tenancy and costs.
• Pay slips or benefit notices (proof) for income changes.
• Written agreements with subtenants or proof of move-ins and move-outs (receipt, log).

Practical tips for handover

When possible, deliver notifications in writing: email with read receipt, registered mail, or personal handover against a signed receipt. Note date and time of every contact.

FAQ

When must I notify the landlord about a new person in the household?

New permanently moving-in persons should generally be notified in writing to the landlord before or promptly after move-in; this protects you and clarifies any lease conditions.

Do I have to report income changes to the housing benefit office?

Yes: changes in income can affect entitlement to housing benefit or rent subsidies and must be reported to the responsible housing benefit office with appropriate proof.^[2]

Where can I turn if the landlord does not respond?

If the landlord does not respond or a regulation is disputed, the local court (Amtsgericht) is responsible for tenancy disputes; you may file a claim there if necessary.^[3]

How-To

1. Step 1: Check which change applies and whether the lease or benefit conditions are affected.
