As a tenant in Austria it is important to know deadlines for key loss and deposit refunds. If you lose keys, inform your landlord promptly and keep documentation to ensure costs and potential liability issues can be clarified transparently. For deposit refunds there are statutory and contractual rules: landlords may withhold part of the deposit in certain cases, but must provide clear accounting. This overview explains which deadlines typically apply, which proofs are useful and which steps tenants can take to protect their rights. You will receive practical advice, useful actions and references to official Austrian sources so you can act safely and informed.

What applies in case of key loss?

When keys are lost: notify your landlord quickly and in writing, clarify whether a lock change is necessary and whether you will be charged. The legal basis for tenancy law is set out in the Mietrechtsgesetz.[1]

Notify the landlord of the loss in writing without delay.
  • Inform immediately, ideally within a few days.
  • Clarify whether locks need to be replaced to ensure security.
  • Clarify who bears the cost: sometimes the tenant, sometimes the landlord.

Deadlines and deposit refunds

There is no single statutory deadline for deposit refunds; typically refunds occur after deduction of legitimate claims and after accounting. If there is a dispute over deductions or amounts, proceedings at the competent district court may be necessary.[2]

Respond to legal letters within deadlines to avoid jeopardising your claims.

When may a landlord make withholdings?

  • For documented damage or unpaid rent the landlord may deduct amounts from the deposit.
  • Each deduction should be supported by receipts, invoices or photographic evidence.
Landlords must be able to plausibly justify deductions.

How long does the refund take?

The timeframe until full refund varies: often accounts are prepared within a few weeks to months. Practically, a tenant should politely inquire after a few weeks and insist on a transparent accounting.[1]

  • Checking after 2–6 weeks is common if no accounting has been provided.
  • The deposit is paid back only after a correct accounting and deduction of legitimate claims.

Documentation and evidence

Keep all receipts: photos at move-out, repair invoices, payment proofs and written communication with the landlord. Good documentation makes enforcing your claims easier and reduces the risk of unjustified deductions.

Detailed documentation increases your chances of success in disputes.
  • Save photos and condition reports at move-in and move-out.
  • Record important messages and deadlines in writing and note the date.
  • Log contact attempts: when and how you informed the landlord.
