Can I reduce the rent for defects?
Yes, for a genuine defect. If the flat is defective — e.g. heating failure, mould, a leaking roof, persistent construction noise, no hot water — the rent is reduced by operation of law under § 536 BGB for as long as the defect lasts. Conditions: the defect is significant (not trivial) and you have reported it to the landlord. The amount depends on severity (reduction quota); courts use guideline tables. Important: don't withhold too much on your own — better pay under reservation or get expert advice.
📋 The rules
- For a significant defect the rent is reduced by law (§ 536 BGB)
- You must report the defect to the landlord (ideally in writing)
- The quota depends on how severe the impairment is
- Reduction is from the gross (warm) rent, for the duration of the defect
- Don't withhold too much yourself — risk of termination for arrears
🔓 Exceptions
- Trivial matters (brief outage, minor defects) don't justify a reduction
- Defects known at signing or caused by you: no reduction
- If you don't report the defect, the reduction claim can lapse
⚠️ Penalties & fines
This is about your rights, not fines. If you reduce justifiably, you only owe the reduced rent; the landlord must fix the defect. But if you withhold too much or without grounds and fall more than two months' rent behind, you risk a termination without notice. Safer to pay disputed amounts under reservation and have the quota checked.

❓ Frequently asked
When can I reduce the rent?
When the flat has a significant defect that impairs its use — heating failure, mould, leaking windows or persistent construction noise. You must report it to the landlord; from then the rent is reduced by operation of law.
How much can I reduce?
It depends on severity. Many defects have guideline values from case law (reduction tables) — from a few percent up to, for total unusability, 100%. The reduction is from the warm rent, for the duration of the defect.
Do I have to report the defect first?
Yes. Only with a defect report to the landlord does the reduction reliably take effect, and the landlord gets the chance to repair. If you don't report it, your claim can lapse entirely.
Can I just transfer less?
Risky. If you set the quota too high and fall more than two months' rent behind, you risk a termination without notice. Better pay disputed amounts under reservation and have the level checked by an expert.
Does it also cover noise from the building site next door?
Often yes, if the noise is significant and lasting. Impairments coming from outside can be a defect too — it depends on the extent and on what was to be expected when the contract was signed.
