Rent Reduction in Austria: Tenant Rights

Rent & increases (reference rent, categories, form) 3 min read · published September 10, 2025
As a tenant in Austria, a defect in your apartment or building can seriously affect daily life. In such cases you often have the right to a rent reduction, but the conditions, deadlines and the correct way to enforce it are not always clear. This guide explains in plain language when a reduction is possible, how to document damage, when you must inform the landlord and which records help in court. It shows practical steps for reporting, setting deadlines and calculating the reduction rate as well as notes on repair obligations and withholding payments. The aim is to help you as a tenant enforce your rights safely and objectively without unnecessary risks. In complex cases, legal advice may be sensible.

What applies to defects?

In Austria, the Tenancy Act (MRG) and general civil law regulate landlords' duties and tenants' rights regarding defects. The decisive factor is whether the usability of the apartment is restricted and whether the landlord is obliged to remedy the defect [1]. Inform yourself about deadlines and possible court steps before withholding payments.

In many cases, a timely written defect notice is a prerequisite for a legally secure rent reduction.

When can tenants reduce the rent?

  • Heating failure or no hot water for a long period.
  • Significant mold infestation, dampness or uninhabitable rooms.
  • Lack of safety measures or significant health risks.
  • Failure of sanitary facilities, electricity or other central services.
Withholding payments can be risky; inform the landlord first and document everything.

How to document defects

Good documentation increases your chances of success: date, photos, written reports and witnesses are important. Keep all receipts and make copies.

  • Photos and videos with date and short descriptions.
  • Written defect notice by registered mail or e-mail with confirmation of receipt.
  • Witness statements or written confirmations from neighbors.
  • Invoices or cost estimates for necessary repairs.
Detailed evidence and a clear timeline strengthen your position in negotiations or in court.

How to reduce the rent?

A rent reduction is measured by the extent of the restriction of use; there is no fixed percentage table. Give the landlord a reasonable deadline for remediation and state a reasonable reduction as a negotiation basis. If no agreement is reached, it may be sensible to resolve the matter at the district court or in conciliation proceedings [2].

Careful action and early communication avoid escalation and costly proceedings.

FAQ

Can I reduce the rent immediately if something breaks?
Not automatically. First you must inform the landlord and give them a deadline to remedy the defect; only in serious defects may an immediate reduction be justified.
How do I calculate the amount of the rent reduction?
The amount depends on the degree of impairment of use. Courts and conciliation bodies refer to cases and comparators; often a percentage reduction is applied relative to the loss of use.
Do I have to hire a lawyer?
Not necessarily. Many cases are settled out of court or before the district court. For complex damage or high dispute amounts, however, legal advice may be advisable.

How-To

  1. Document defects immediately with photos, date and description.
  2. Send a written defect notice to the landlord and request a deadline for remediation.
  3. Set a reasonable follow-up deadline and state how you will justify the reduction.
  4. If no agreement is reached, submit documents to the conciliation body or the district court.

Key Takeaways

  • Documentation is the basis of any successful rent reduction.
  • Written defect notice and deadline setting are crucial.
  • Seek legal advice for larger disputes.
