Enforce Rent Reduction — Tenants in Germany

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

Many students in Germany face housing defects in 2025, from heating failures to mold. A rent reduction claim allows tenants to reduce or retroactively lower rent when the apartment is defective. This text explains clearly what rights tenants have, which deadlines apply and which evidence (photos, correspondence, logs) is important. I also describe how formal letters are structured, which official forms or court steps are possible and how to avoid risks such as threats of termination. The goal is to give students practical steps so they can enforce their claims in Germany in a documented and legally secure way.

What is a rent reduction claim?

A rent reduction claim means the rent is reduced when the living quality is significantly impaired by a defect. Legal foundations are found in the German Civil Code (BGB) regarding landlord duties and rent reduction[1]. The extent, duration and whether the landlord was informed are decisive.

Sections §§ 535–536 of the BGB set out the basics for rent reduction.

When can tenants reduce rent?

Tenants can reduce rent as soon as a defect exists that impairs the fitness of the apartment and the landlord does not remedy it in time. Formal defect notifications and deadlines are important; in doubtful cases there are leading Federal Court (BGH) rulings on the amount and effectiveness of reductions[2].

What students should particularly watch for

  • Take dated photos and videos of the defect.
  • Report the defect in writing to the landlord and set a reasonable deadline for repair.
  • Document deadlines: when reported, when followed up, what reply arrived.
  • Do not advance large repair costs without consultation; keep receipts for small emergency expenses.
Keep all receipts and photos securely stored.

If the landlord does not respond, a formal letter with a deadline and threat of legal steps usually helps; as a last resort a lawsuit before the competent local court may follow. Jurisdiction and procedural rules derive from the Code of Civil Procedure (ZPO).

How-To

  1. Step 1: Report the defect in writing — date, precise description, and a deadline (e.g., 14 days).
  2. Step 2: Gather evidence — photos, witness statements, emails and messages.
  3. Step 3: Monitor deadlines — track responses and follow up in writing.
  4. Step 4: Seek advice — tenant association or legal counsel should review documents and prospects.
  5. Step 5: Court action — if necessary file suit at the local court.
Respond to legal letters within stated timeframes to protect your rights.

FAQ

What evidence helps with a rent reduction claim?
Photos, timestamps, written defect notices to the landlord, witness statements and repair invoices are central to successful enforcement.
Should I stop paying rent entirely?
No. A proportional rent reduction corresponding to the loss of use is common; stopping payments entirely without legal basis is risky.
Which court handles this?
Most tenancy disputes fall to the local court (Amtsgericht); appeals go to the regional court, and the Federal Court (BGH) addresses legal precedent issues[2].

Key Points

  • Set and document deadlines clearly.
  • Collect and secure all evidence.
  • Send a written defect notice to the landlord.
