Danish law allows short-term rental of your home, but your type of ownership and your association decide whether you can actually do it in practice. The answer is completely different for condominiums, co-ops and rentals, and many people get it wrong.
If you own a condominium, you are generally allowed to short-term rent it. For the association to restrict this, it needs a general meeting decision with at least a two-thirds majority by both distribution figure and number of owners, and the restriction has to be written into the registered bylaws. Under the modernised Condominium Act from 2020 and the standard bylaws from the same year, even if the association has adopted a ban you keep the right to up to 4 separate rentals and no more than 30 days in total per calendar year. Short-term rental is defined here as stays under 31 days.
In a co-op association the opposite applies. Short-term rental is generally not allowed unless the association's bylaws open for it, and most bylaws require the board's consent for any form of sub-letting. If you rent your home, you cannot short-term rent it without your landlord's approval, and renting without consent can cost you the lease. Always get the approval in writing.
Remember that the 70-night cap in Copenhagen and the tax rules apply regardless of ownership form. The association's bylaws can only tighten, never loosen, the public rules. Pull up the registered bylaws from tinglysning.dk, search for short-term rental, sub-letting and Airbnb, and get the board's answer in writing.
