Rent & indexation (CPI/index, caps) 3 min read · published September 11, 2025
As a tenant in Norway, you have rights when the dwelling has defects that affect use or safety. This guide explains what rent reductions may apply, what you should document, and how to notify the landlord under the Tenancy Act. We cover deadlines, evidence that strengthens your case, and when it may be necessary to take the matter to the Tenancy Tribunal (HTU) or the courts. The language is simple and practical, with steps you can follow without legal expertise. If you follow the advice here, you will get an overview of the process and better chances of achieving a fair rent reduction or other compensation.

What gives the right to rent reduction?

Tenants may be entitled to a rent reduction when a defect reduces the use of the dwelling or creates health risks. Which defects qualify and how this is assessed follows from the Tenancy Act[1], but the assessment depends on the seriousness of the defect and the practical consequences for the tenant.

In most cases the defect must be material to give the right to a reduction.

Common examples of defects

  • Repair / reparasjon affecting heating, water, or safety.
  • Loss of use that entitles a reduced rent / husleie.
  • Repeated problems not fixed after written notice / varsling.
  • Lack of documentation of previous faults reduces the chance of compensation / dokumentasjon.
Document everything with dates, photos, and written communication.

How to notify the landlord

Notifications should be written and clear: describe the defect, how it affects you, and what you demand. Give a deadline for repair and ask for written confirmation. If the matter is not resolved, HTU can assist with dispute resolution[2].

  • Send a written notice / varsel describing the defect and demanding repair or rent reduction.
  • Take photos and keep a dated log / journal of the issues.
  • Give the landlord reasonable time to remedy the defect / reasonable time.

How to calculate a rent reduction

The calculation is case-specific and often assessed as a percentage based on how much use has been lost. There is no fixed table in the law; courts and HTU consider duration, scope, and what was agreed in the lease.

  1. Determine the extent of the defect with documentation.
  2. Assess what share of use was lost to calculate a percentage reduction.
  3. Note dates when the defect started and when it was fixed.
  4. Contact HTU or the conciliation board if you cannot agree on percentage or amount / forliksrådet.
Respond promptly to notices to preserve your rights.

Frequently Asked Questions

Can I withhold rent if the landlord does not fix the problem?
As a rule, you should not unilaterally withhold payment without a clear agreement; demand a rent reduction in writing and follow procedures in the Tenancy Act.
