Is Airbnb legal in Copenhagen?

Yes, but it’s regulated. The framework is set by Danish law (sommerhusloven), and the City of Copenhagen supervises the residence requirement.

The 70-night limit

You may rent out your primary residence up to 70 nights per year via platforms that report to the authorities. Airbnb reports automatically. Renting out a single room while you are present is treated more flexibly than renting the whole home.

The three tiers, in short

The rule has three tiers and the difference is worth money. If you rent out on your own, without a platform that reports to the Danish tax authority, the cap is 30 days a year. If you rent through an intermediary that reports automatically, such as Airbnb, the cap is 70 days. A municipality can choose to raise it to 100 days, and twenty have, including Odense, Roskilde and Bornholm. Copenhagen and Frederiksberg have not.

Primary residence and CPR

The property must be your registered home (the address tied to your CPR). Investment flats and second homes don’t qualify for the 70-night allowance.

What counts as your primary residence

Your primary residence is the home registered to your CPR, the address where you actually live day to day. You can rent it out while you are away travelling or working, as long as it stays your real home on paper. A flat you own but do not live in does not qualify, so the 70-night allowance does not apply to it and stricter rules take over.

How the reporting works

Airbnb collects your CPR and reports your nights and income directly to the Danish Tax Agency. That automatic reporting is exactly what gives you the higher 70-night allowance. Without a reporting platform the cap is 30 nights per year, with a reporting platform 70 nights, and a municipality can raise the cap to 100 nights, but Copenhagen has not done so.

Renting out a single room

If you rent out a single room while you live in the home yourself, the setup is treated more flexibly than renting the whole home. Via a reporting platform the tax-free allowance is the same 35.100 kr in 2026 whether you rent a room or the whole home. The real difference is that renting a single room while you live there is not capped by the 70-night rule.

Tax

There are specific tax rules and a 35,100 kr tax-free allowance on short-term rental income; everything above it is taxable. Confirm your exact situation with SKAT or an accountant.

Building rules

Many andelsforening and ejerforening associations restrict or fully ban short-term rental regardless of what city law allows. Always check your bylaws and any board decisions first.

Enforcement: what actually happens

The City of Copenhagen has set aside 3,6 million kr for a housing patrol of around 15 staff. The city does not, however, have the legal authority to check how many days you rent out. That is stated in the city's own written response of 3 March 2025: the reporting obligation covers income, not the number of days. What the city supervises is the residence requirement, which is a separate rule.

A political agreement from January 2026 proposed fines from around 5.000 kr up to 100.000 kr. It was never turned into legislation before the general election of 24 March 2026, so those fines do not yet apply. For comparison, the October 2025 evaluation by the Danish Planning and Rural Districts Agency shows that between 2019 and May 2025 thirteen cases about renting out one's own year-round home were closed, with no enforcement notices, no fines and no police reports.

On 21 May 2026 the City Council voted on raising the cap from 70 to 100 days. The proposal was rejected, 50 votes to 3. The cap in Copenhagen therefore remains 70 days. See Was the cap raised to 100 days? for the full breakdown.

A short checklist before you start

Confirm the home is your registered CPR address. Check your association bylaws for any short-term rental restrictions. List on a platform that reports automatically, like Airbnb, so you keep the 70-night allowance. Keep a running count of your nights so you never pass 70. Set money aside for tax on anything you earn above the allowance.
