Rent Reduction for Defects in Denmark

Rent, regulation & indexation 2 min read · published September 11, 2025

What applies to deadlines for rent reduction?

As a tenant in Denmark you must act within certain deadlines to assert claims for defects in the dwelling. First you should notify the landlord in writing and allow time for remedy; thereafter the deadlines depend on the nature of the problem and whether you want rent reduction, repair, or compensation.[1]

Always date your messages and keep copies.

When do the deadlines start?

Deadlines typically start from when the defect is discovered or should have been discovered. If you find damage or a condition that affects the usability of the dwelling, you should immediately notify the landlord in writing and document the issue with photos and descriptions.

  • Notify the landlord immediately in writing and set a reasonable deadline for remedy.
  • Document the defect with dates, photos and correspondence.
  • Allow access if the landlord wants to repair the defect, but maintain your claims if the work is insufficient.
Detailed documentation increases your chances of success in a case.

What affects whether you can get rent reduction?

The right to reduction depends on the extent, duration and whether the defect significantly reduces the rental value. Minor cosmetic issues rarely give full reduction, while lack of heating, damp or mold often justify larger claims.

  • Lack of heating or serious damp can justify significant rent reduction.
  • Minor faults may only justify a proportional small reduction.
  • In some cases you can claim repayment for incurred extra expenses or increased consumption.

How to complain — the short steps

If the landlord does not remedy or rejects your claim, you can bring the case before the housing tribunal or ultimately the courts. The housing tribunal is often the first instance for disputes about rent reduction and other tenancy issues.[2]

  1. Send a written complaint to the landlord and document the response.
  2. Contact the housing tribunal or get guidance if the dispute is unresolved.
  3. Bring the case to the housing tribunal; if necessary the case can proceed to the district court.
Respond to inquiries within stated deadlines to avoid losing rights.
