Rent Reduction in Germany — Your Right as a Tenant
Defects in your apartment? You have the right to reduce your rent. Learn when a reduction is possible, how much you are entitled to, and how to create a legally sound letter to your landlord for free online — without a lawyer.
What is a rent reduction (Mietminderung)?
A rent reduction is the legal right to pay less rent when your apartment has a defect that significantly affects your quality of living. This right is based on Section 536 BGB and takes effect automatically by law — you do not need permission.
Important: The reduction applies from the day the defect occurred — not from the day you write a letter. The only requirement is that you have notified the landlord of the defect.
Reasons for rent reduction — when is it possible?
A rent reduction is possible for any significant defect that limits the usability of the apartment. The most common reasons are:
- Mold in the apartment
- Heating failure or defective heating
- Water damage and moisture
- Noise from neighbors, construction, or businesses
- Power or gas failure, no hot water
- Elevator failure
- Pest infestation

Rent reduction and BGB — the legal basis
The right to rent reduction is anchored in the German Civil Code (BGB). The key sections:
- § 536 BGB — Rent reduction for material and legal defects — the core provision
- § 535 BGB — Landlord's maintenance obligation — the apartment must be usable as agreed
- § 536a BGB — Damages and self-remedy when the defect is not fixed
- § 536c BGB — Tenant's notification obligation — you must report defects immediately

Rent reduction without a lawyer — in 4 steps
You do not need a lawyer to enforce your rent reduction. The right to reduce rent exists by law (§ 536 BGB) — you just need to assert it correctly. Here is how:
1. Document the defect
Record the defect in writing and with photos. Note the date the defect first appeared and how it affects your quality of living. For heating failures, temperature logs help; for noise, keep a noise diary with times and duration. The more detailed your documentation, the stronger your position.
2. Notify the landlord (Mängelanzeige)
Inform your landlord in writing about the defect — by registered mail with return receipt or in person with written confirmation. Set a reasonable deadline for repair: usually 14 days, or shorter for urgent defects (heating failure in winter). Without a defect notification, no rent reduction — this step is mandatory.
3. Calculate the reduction amount
Determine what percentage of rent reduction is appropriate in your case. The calculation is based on the gross warm rent (base rent + utilities). Use court rulings for comparable defects as guidance. Our rent reduction calculator helps you with this.
4. Reduce rent or pay under reservation
You have two options: Either reduce the rent directly by the calculated amount, or pay the full rent under reservation of reclaiming the difference. The second option is safer — if you reduce too much, you risk termination for non-payment. Keep all receipts and correspondence carefully.
