What is the Richtwertmiete?

The Richtwertmiete in Austria is an orientation value used as a benchmark for market rents of privately financed rental properties. It takes into account the year of construction and level of equipment and is used in rent tables and calculation bases. The Richtwertmiete itself is not automatically the applicable rent, but indicates the average amount demanded on the market. For certain apartment types and tenancy agreements it influences whether and how much a rent increase is legally permissible.[1]

Check the construction year and equipment value in your lease before accepting a rent increase.

When can the landlord raise the rent?

A rent increase may be possible if contractual agreements, legal rules or indexed adjustments permit it. The legal situation differs between old and new buildings and between capped and freely financed rents. Deadlines, formal requirements and the exact calculation method are important.

  • Observe deadlines: rent increases often must be announced in writing and include deadlines.
  • Formal requirements: many increases are only effective if made in a specific form.
  • Check the amount: compare the requested sum with the Richtwert and the category rent.
Respond in writing and within deadlines to landlord offers of rent increases.

Category and Richtwert rent explained

Category rent assigns apartments to categories by equipment and location; each category has an associated Richtwert. Landlords must not change the category arbitrarily. Adjusting rent to the category rent requires transparent calculation and often an explanation to the tenant.

How tenants check an increase and document it

If you receive a rent increase, first check the lease, past statements and the calculation of the increase. Request documents and calculation bases, note deadlines and communicate in writing. Documentation increases your chances in formal reviews or court proceedings.[2]

Thorough documentation increases your chances of success in disputes.
