This guide is about consequences, not about what you are allowed to do. What does going over the limit cost, who checks, and what does the January 2026 political agreement change?
The limits themselves did not change in 2026. Letting privately without a reporting platform, the cap is 30 days a year. Through a platform that reports to the Danish Tax Agency, the cap is 70 days a year. A municipality may raise its own limit to 100 days. Copenhagen has not, and the city council voted no on 21 May 2026.
The fine level under sommerhusloven, as applied today, is around 5.000 kr for an overrun of up to 5 days, rising with the length of the overrun, up to 100.000 kr for overruns of 180 days or more. An order from the authorities that is not complied with carries a separate fine of 25.000 kr each time.
On 22 January 2026 the Danish government and the parties behind the agreement, through By-, Land- og Kirkeministeriet, agreed a package against illegal short-term rental: markedly higher fines under sommerhusloven, a duty for platforms and owners to hand over information in specific cases, the power to have illegal listings blocked, the option for municipalities to take over supervision, and an evaluation in 2028.
This is a political agreement, not yet law. The bill was to go to public consultation during the first half of 2026, and when it takes effect depends on the Danish parliament. Read it as what is coming, not as what already applies. The platforms already report income to the tax authority, so the number of nights is visible, and the direction of travel is more data sharing and higher penalties. We are not lawyers, so ask yours if you are in doubt.
