When are you allowed to sublet?

In general, subletting requires your landlord's consent. However, Danish tenancy law gives you the right to sublet in certain situations even without it.

Temporary subletting (max 2 years): You have the right to sublet for up to 2 years if you have a legitimate reason — for example: a temporary stay abroad (study, work, secondment); a temporary stay elsewhere in Denmark; or hospitalisation. The reason must be stated in §11 of the sublease agreement.

Subletting a room: You can sublet a room without your landlord's consent, as long as the property is your primary residence and you continue to live there. The total number of occupants (including the subtenant) must not exceed the number of rooms.

Short-term/Airbnb-type rental: Commercial short-term letting in a rented apartment is generally not permitted under Danish law and is often explicitly banned in §11.

What must a sublease contract contain?

A sublease must be in writing — you can use Typeformular A10 and mark it as a sublease. It must include: names of both parties; address and which rooms are covered; rental period; rent amount and deposit; and the reason for subletting (in §11 if time-limited). You cannot charge more than you pay in rent yourself.

Your responsibilities as sublessor

You remain responsible to your landlord as if you were still living there. If the subtenant doesn't pay rent or damages the property, you're liable. Your landlord can in some circumstances terminate your tenancy if the subtenant repeatedly breaches house rules. You must give your landlord a copy of the sublease before the subletting period starts — this is a legal requirement.
