As a tenant in Austria, you may pay a cost-based rent or be entitled to refunds. This text explains in simple steps how to draft a legally sound template letter, which deadlines apply, which evidence you should collect and how to assert the claim against the landlord. I describe wording, checking receipts and practical tips for submitting or delivering the letter. You will also learn which authorities and courts in Austria are relevant if an agreement is not possible and which documents are useful before proceedings. The aim is to give you concrete action steps and templates so you can enforce your rights more confidently.

What are cost rent and refunds?

Cost rent often refers to the passing on of certain operating costs or calculated expenses to the tenant. A refund may be due if errors appear in accounting or if advance payments were too high.

In most cases, tenants are entitled to clear accounting.

Key steps

  1. Check deadlines and contractual requirements.
  2. Collect invoices, payment receipts and contracts.
  3. Draft a clear template letter to the landlord.
  4. Request repairs or accounting corrections if necessary.
  5. If in dispute: consider legal advice or court proceedings.
Respond to deadlines promptly, otherwise rights may be lost.

Evidence and wording

Clean documentation is crucial for a successful claim. Use clear language in the template letter and state exact amounts, periods and reference numbers.

  • Invoices and detailed operating cost statements.
  • Payment receipts such as transfers or receipts.
  • Lease agreement and any side agreements on cost rent.
  • Record questions or objections in writing and date them.
Keep all payment receipts and invoices securely stored.
