Can I reduce the rent for defects in Austria?
Yes — for defects you may reduce the rent. Under § 1096 of the Civil Code you are entitled to reduced (or zero) rent while the flat is unusable or impaired through no fault of yours — whether the MRG fully, partly or doesn't apply. Typical defects are mould, heating or hot-water failure, water damage, leaking windows or serious construction noise. There's no fixed percentage table — the amount depends on how much the use is impaired and is decided by the court if disputed. It's usually calculated on the gross rent and pro-rated by days. Report the defect at once and reduce conservatively. In short: yes, but with judgement and after notifying the defect.
📋 The rules
- Right under § 1096 Civil Code for defects
- E.g. mould, heating failure, water damage
- Amount by degree of impairment
- Usually calculated on the gross rent, by days
- Report the defect first, reduce carefully
🔓 Exceptions
- No reduction for self-caused defects
- Heating failure only counts in the winter months
- For a dangerous defect, possible even without formal notice
⚠️ Penalties & fines
There's no state fine — this is a civil remedy. The big practical risk is over-reducing: if you cut more than a court later deems justified, you create a rent arrear that can trigger an eviction claim. Beware a myth: "I just stop paying rent entirely until it's fixed" is risky — full non-payment is only justified if the flat is wholly unusable; otherwise you owe the unreduced portion and risk losing the flat. Tip: report the defect in writing with photos, reduce conservatively, and have the amount checked by the Chamber of Labour or tenants' association.

❓ Frequently asked
When can I reduce the rent?
If the flat is defective through no fault of yours and its use is impaired as a result, you have a right to a rent reduction under § 1096 of the Civil Code. Typical cases are mould, a failure of heating or hot water, water damage, leaking windows or serious construction noise.
How much can I cut?
There is no fixed percentage table. The amount depends on how much the use of the flat is actually impaired and is assessed by the court if disputed. A heating failure, for example, only matters in winter, while a lack of hot water affects use all year.
Must I report the defect first?
Yes, you should notify the landlord of the defect at once, ideally in writing, and document it with photos. Only for a dangerous defect has the Supreme Court allowed a reduction even without formal notice. Prompt notification is always advisable, however.
Can I stop paying altogether?
Only if the flat is wholly unusable. Otherwise full non-payment is risky, because you still owe the unreduced portion. If you cut too much, you create a rent arrear that can lead to an eviction claim.
What is the reduction calculated on?
The reduction is usually calculated on the gross rent, including operating costs, and pro-rated by days if the defect lasts only part of the month. When in doubt, have the specific amount checked by the Chamber of Labour or tenants' association.
