Lease types (fixed/indefinite, main/sublet) 3 min read · published September 10, 2025
As a tenant in Austria, you may wonder whether a landlord can charge reasonable subrent and under which conditions that applies. This text explains clearly which rights and duties tenants and subtenants have, when the main landlord's consent is required, which costs are permissible and how you can respond if an additional fee is demanded. We show practical steps for documentation, filing objections and court clarification as well as pointers to relevant laws. The aim is to give you, as a tenant, orientation so you can make informed decisions and effectively exercise your rights in tenancy matters in Austria.

When is subrent permitted?

In principle, subrent is possible in many cases, but much depends on the main lease and applicable tenancy law. The Mietrechtsgesetz (MRG) and the general provisions of the ABGB determine under which conditions a subtenancy arises and what consent obligations exist[1]. If the lease does not expressly prohibit it, a tenant can often sublet, but must observe proportionality and the agreed contractual terms.

In many cases, the landlord's consent is required when the lease demands it.

What does "reasonable" subrent mean?

"Reasonable" means the landlord's claim should not be far above market-based costs. Permissible elements include proportional rent, operating costs and proven ancillary costs; pure mark-ups without basis are problematic. Comparable properties and contractual agreements are decisive.

  • Proportional agreed rent or a share of the main rent that is market-typical.
  • Operating costs and utilities if transparently billed.
  • Administrative costs only if clearly contractually based.
Keep all receipts and billing records for ancillary costs.

When does the landlord need to consent?

Many main leases require prior landlord consent for subrent. If such a clause is missing, the situation is more open, but a landlord can assert legitimate interests in certain cases (e.g., overcrowding, change of use). Formal consents should be in writing to avoid later disputes.

  • Request written consent if the lease requires it.
  • Record duration, subtenant name and agreed costs in the consent document.
Without written consent you will often face evidentiary problems in later disputes.

If you receive an extra charge

If you are suddenly charged an extra subrent fee or surcharge, first check the contract and bills. Request a detailed breakdown of the claimed amounts. If you disagree, communicate in writing and keep an eye on deadlines.

  • Document written claims by email or letter and save all replies.
  • Discuss with the landlord and propose a compromise if appropriate.
  • If unresolved, seek court clarification at the district court; documents and deadlines are important for this step[2].
Respond in writing to claims and keep all receipts.

FAQ

Can the landlord simply demand a flat fee for subtenants?
No, flat fees are only permissible if contractually agreed or market-based and demonstrable.
Do I always need the landlord's permission to sublet?
Often yes if the lease requires consent; otherwise it depends on the specific circumstances.
Where can I turn if the landlord demands money without basis?
Document everything, seek dialogue and consider court clarification or tenant advice services.
