Rent Increase Complaints in Norway — Tenant Rights

Tenant rights & basic protections 3 min read · published September 11, 2025
As a tenant in Norway, a sudden rent increase can be stressful and unclear. This section explains what rights you have, how to assess whether the increase is lawful, and which deadlines apply for filing a complaint. You will get concrete advice on documentation, communication with the landlord and how you can proceed to the Tenancy Disputes Board (HTU)[2] or the courts[3] if the matter is not resolved. We also describe what may be unreasonable in the contract, when temporary agreements apply, and how deposit and rent payments are affected during a dispute. The aim is to provide practical, step-by-step actions that make it easier to protect your rights without legal background.

What to do first

The following actions help you assess the rent increase and prepare a possible complaint.

  • Check the tenancy agreement for terms on termination and rent changes.
  • Verify whether the increase matches what is agreed or lawful under the Tenancy Act.
  • Gather documentation: previous rent receipts, the landlord's notice, and correspondence.
  • Record dates and deadlines for notice and responses from the landlord.
  • Contact the landlord in writing first; request justification if it is unclear.
Keep all written communication as evidence.

Which rules apply

The Tenancy Act governs when and how rent can be changed and the procedures to follow in disputes.[1] In many cases the increase must be reasonably justified and given with adequate notice. If the landlord does not comply with law or contract, you can object in writing and request a reassessment of the change.

Respond to written notices within deadlines to protect your rights.

How to complain formally

If the landlord rejects your objection, you can submit a formal complaint to the Tenancy Disputes Board or bring the case to court. Start with a short, factual complaint that describes what happened, attach relevant documentation and state which rights you consider violated. Guidance is available from the Tenancy Disputes Board on how cases are typically handled.

HTU can mediate or issue decisions in many tenancy cases. If the matter concerns complex contractual issues or larger claims, it may be appropriate to proceed to the district court.

Detailed documentation increases your chances of success in a dispute.
