How does platform subletting work?

Platform subletting refers to temporary rentals often arranged through services that connect landlords and short-term tenants; legal principles are based on the Act on Residential Leases.[1] Often landlord permission is required for subletting or platform subletting, and the lease terms determine permitted use. Tenants should always request permission in writing and keep communications as evidence.

Detailed documentation improves your chances in a dispute.

Act immediately if problems arise

  • Notify the landlord in writing about defects and request repairs.
  • Collect photos, messages and receipts as evidence.
  • Keep receipts of rent payments and maintain a clear payment history.
  • Consider contacting advisory services before legal action.

Where can I get help in a dispute?
You can seek advice from local advisory services, turn to the Consumer Disputes Board or, if necessary, bring the matter to court.[3]
