The article refers to official sources and explains legal terms without legal jargon.

What do the rules say about smoke alarms and fire safety?

The starting point in Denmark is that homes must be safe and defensible. The landlord typically has responsibility for installation and major maintenance, while the tenant must handle daily operation and report faults promptly. See the Rent Act for exact duties and deadlines[1].

In many cases, it is the landlord who must ensure correct installation of the smoke alarm.

When and who should act?

Here are practical points about who does what and which deadlines often apply:

  • Tenant: check the smoke alarm at least once a month (within).
  • Landlord: install and ensure replacement in case of technical failure or unit replacement (repair).
  • Notification: send written notice to the landlord as soon as possible and set a clear deadline (file).
  • Documentation: take photos, note date and time, and keep receipts for repairs (evidence).
Keep all messages and photos in one folder so your documentation is organized and clear.

What do you do about faults or missing smoke alarms?

Follow these steps: contact the landlord immediately in writing, describe the fault, suggest an access time for repair and set a reasonable deadline. If the landlord does not respond, you can bring the case to the Rent Tribunal or seek legal advice. Remember to document everything in writing and keep evidence[2].

Respond to written summons within the deadline to preserve your rights.

What can you demand financially?

If the landlord fails to remedy faults, the tenant may in some cases demand rent reduction or reimbursement for necessary repairs. This typically requires clear documentation and possibly a decision from the Rent Tribunal or the courts.
