COPENHAGEN — In the cobbled lanes of Copenhagen’s historic Medieval Town, a quiet crisis is unfolding. Once vibrant with local life—students, retirees, young professionals sharing courtyards and complaints about recycling—many buildings now feel more like transient hotel corridors than homes. The culprit? An explosion of unregulated short-term rentals, primarily through platforms like Airbnb.
Residents like Kren Nielsen, chairman of the Round Tower Residents’ Association, are sounding the alarm. “It ruins good neighbourliness,” he says, standing near Kongens Nytorv, one of the city’s most picturesque squares—and now, one of its most affected by tourism-driven housing displacement.
Nielsen’s frustration is palpable as he points to a single building entrance lined with no fewer than 11 key boxes. “We’ve walked 100 meters, and I’ve already shown you two examples like this,” he notes. These unmarked lockboxes—often hidden under benches or tucked in stairwells—are the telltale signs of what locals call “shadow hotels”: apartments converted into de facto commercial accommodations, often operating outside the law.
The Erosion of Community—and Compliance
At the heart of the issue isn’t just noise or litter—though those are real concerns voiced by neighbours like pensioner Peter Hertz, who lives near a former office space now rented out weekly via Airbnb. “It’s nice to have tourists,” Hertz concedes, “but it can be too much.” His building now sees a revolving door of strangers, late-night smokers in shared courtyards, and overflowing bins.
More fundamentally, the surge in short-term rentals is hollowing out the social fabric of Copenhagen’s dense urban neighbourhoods. “When you have apartments constantly occupied by guests instead of neighbours, you lose the trust, the familiarity, the informal support systems that make dense city living work,” Nielsen explains.
Compounding the problem is widespread non-compliance. Danish law currently limits private short-term rentals to 70 days per year—but enforcement is weak, and loopholes abound. Many operators flout these rules, registering multiple units under different names or converting commercial spaces into unlicensed lodging. In extreme cases, entire buildings operate as unofficial hotels with no permanent residents at all.
A National Problem, Not Just a Capital One
While Copenhagen bears the brunt, the issue has spread beyond the capital. In Aarhus, investigative reporting by Jyllands-Posten recently uncovered a full-scale shadow hotel operating out of the port district—highlighting that the regulatory gap is a national concern.
This isn’t a new phenomenon in Europe. Cities like Amsterdam and Berlin implemented strict controls years ago: requiring municipal permits for short-term rentals, enforcing primary residency requirements, and capping the number of rental days far below Denmark’s current 70. The result? More stable housing markets and preserved neighbourhood character.
Denmark, by contrast, has been slow to act—until now.
New Rules on the Horizon
Later today, Energy and Housing Commissioner Dan Jørgensen is set to unveil a sweeping housing reform package that directly targets the short-term rental sector. The proposal aims to empower local municipalities with new enforcement tools to crack down on illegal operators who “use short-term rentals as a money machine,” as Jørgensen described it in a statement to DR Nyheder.
Key elements expected include:
- Stricter verification mechanisms for rental listings;
- Enhanced municipal authority to inspect and penalise non-compliant properties;
- Tighter alignment with housing policy goals, including curbing rent inflation and addressing acute housing shortages.
This follows a November proposal from the Danish government that began to outline regulatory guardrails—but many, including Nielsen, argue it didn’t go far enough. “We should learn from Amsterdam and Berlin,” he insists. “Waiting until neighbourhoods are hollowed out is too late.”
Why This Matters for Nordic Business
For our readers—investors, urban planners, policymakers, and housing stakeholders—the Airbnb issue transcends tourism. It’s a critical indicator of housing market health, urban liveability, and regulatory agility.
Unchecked short-term rentals distort housing supply, pushing long-term residents out of central neighbourhoods and inflating prices in already-tight markets. In Copenhagen, where housing shortages are acute and affordability is a growing political flashpoint, this isn’t just a nuisance—it’s a systemic risk.
Moreover, the rise of shadow hotels represents a form of regulatory arbitrage: operators gain hotel-like revenues without paying commercial taxes, meeting safety standards, or contributing to local infrastructure. This creates an uneven playing field for licensed hotels and small landlords who follow the rules.
The forthcoming reforms could signal a turning point—not just for Copenhagen, but for the broader Nordic approach to the platform economy in urban space. Will Denmark embrace proactive, community-centred urban governance? Or will it continue reacting to crises after they’ve already taken root?
One thing is clear: the residents of Medieval Town aren’t waiting for an answer. They’re already counting key boxes—and hoping their city still has room for neighbours, not just guests.
