EU Short-Term Rental Regulations 2026: What the Data Shows About Markets Under Pressure

by Jun ZhouFounder at AirROI

Published: March 19, 2026

The fear narrative is predictable: regulation kills revenue. But AirROI data from five major European markets tells a different story. Amsterdam, operating under Europe's strictest 30-night annual cap, maintains a $307.60 average daily rate -- the highest among the markets we analyzed. Barcelona, facing a complete phase-out of 10,101 tourist apartment licenses by November 2028, still generates $26,510 in median annual revenue with 58% occupancy. The EU's new framework reshapes STR economics rather than eliminating them, and the data reveals exactly how.

What EU Regulation 2024/1028 Actually Requires

As Ben Schroeter, Director for Economic Policy at Booking.com, wrote in The Regulatory Review: the regulation "materially alters evidentiary standards for policymaking" by providing property-level activity data that enables rigorous empirical analysis, "simultaneously empowering and constraining regulators."

Here is what the regulation requires:

Host obligations: Register with the competent local authority where a registration scheme exists. Provide standardized information including property address, type, capacity, and residency status. Display the assigned registration number on all platform listings.

Platform obligations: Collect and verify registration numbers before listing properties. Display numbers prominently. Conduct random compliance checks via member state APIs. Transmit standardized monthly activity data -- including nights booked, guest counts, and property addresses -- to national Single Digital Entry Points. Remove non-compliant listings upon valid authority requests.

Member state obligations: Establish a national Single Digital Entry Point by May 20, 2026. Appoint a national coordinator. Determine penalties for non-compliance by platforms and hosts.

What the regulation explicitly does not do: legalize STRs EU-wide, override national housing policy, require universal registration in every jurisdiction, or impose EU-wide night caps. Local rules still govern what is legal and where -- the EU provides the data infrastructure to enforce those rules consistently.

Country-by-Country Compliance Map: Where the Rules Are Tightest

The EU framework creates a baseline, but enforcement intensity varies dramatically by country. France captured 192 million guest nights in 2024, Spain 171 million, Italy 127 million, Germany 60 million, and Greece 45 million. Each is implementing the regulation against a backdrop of pre-existing local rules that range from moderate to aggressive.

Spain -- First to Comply, Hardest to Ignore

Spain became the first EU country to implement a compliant registration scheme through Royal Decree 1312/2024. Since July 1, 2025, every STR listed on a platform must display a national registration number (NRA). Platforms must remove listings without an NRA within 48 hours. The registration fee is EUR 27.

Despite these restrictions, AirROI data shows Barcelona's 14,573 active listings maintain a $250.10 ADR and 58% occupancy, generating $26,510 in median annual revenue. The shrinking supply of licensed properties is driving premium pricing for compliant operators. For hosts with existing licenses, the window through 2028 offers strong revenue potential -- but no path to renewal.

France -- The 120-Night Enforcer

Paris enforces a 120-night annual cap on primary residence STR rentals, with platforms automatically blocking calendars beyond the limit. Fines escalate sharply: EUR 10,000 for failure to register, EUR 50,000 for renting a secondary residence without a change-of-use authorization, and EUR 12,500 per non-compliant listing for platforms. The city maintains a dedicated enforcement brigade monitoring tourist rentals.

France's national law strengthened these tools in November 2024, and a national declaration portal rolls out by May 20, 2026, aligned with the EU deadline. Principal residence limits in Paris and Lyon become more enforceable because booking activity can now be matched to registration records through platform data sharing.

With 59,421 active listings, Paris is Europe's largest STR market by volume. AirROI data shows a $262.60 ADR and 55% occupancy, generating $21,834 in median annual revenue. The enforcement infrastructure is mature -- hosts who operate within the 120-night framework face a well-defined, manageable compliance environment.

Netherlands -- The 30-Night Experiment

Amsterdam operates the strictest night cap in Europe: 30 nights per calendar year for primary residences, with a EUR 73 permit requirement. The city is considering reducing the cap to 15 nights in central zones like Centrum and De Pijp from April 2026 under its "Holiday Rental Escalation Ladder."

Oxford Economics estimates EUR 269 million in lost host earnings since the implementation of Amsterdam's current restrictions. Yet the market data reveals a counterintuitive outcome. AirROI data shows Amsterdam's 8,371 active listings achieve a $307.60 ADR -- the highest among the five markets analyzed -- with $25,803 in median annual revenue despite the severe night cap.

Italy -- CIN Codes and Climbing Tax Rates

Italy's CIN (Codice Identificativo Nazionale) became mandatory for all short-term rentals on January 1, 2025. The code must appear on the property's exterior and on all online listings. Non-display triggers fines of EUR 800 to EUR 8,000.

Tax policy is tightening. The current structure applies a 21% cedolare secca (flat tax) on the first rental property and 26% on additional properties. The 2026 budget law dropped the threshold for mandatory business registration from four properties to two -- hosts with three or more STRs must now register for VAT and operate as a business. A proposed standardization of the flat tax at 26% for all properties is under parliamentary debate.

Italy also eliminated key-box-only check-ins. Hosts must verify guest identities visually, either in person or via video intercom. AirROI data shows Florence's 12,197 active listings maintain a $224.40 ADR and 52% occupancy, generating $24,729 in median annual revenue.

Greece -- The Data Cross-Reference Pioneer

Greece is implementing the most sophisticated enforcement technology in Europe. Under Law 5170/2025, the country created a unified property register linking tax declarations, property records, platform data, bank accounts, and credit card payments. The AADE (Independent Authority for Public Revenue) cross-references all data sources to identify non-compliant hosts.

The Regulation-Revenue Paradox: AirROI Data from 5 European Markets

The data from 109,000+ active listings across five European markets challenges the assumption that regulation destroys STR revenue. The two strictest markets -- Amsterdam (30-night cap) and Barcelona (license phase-out) -- generate the highest ADR and near-highest annual revenue among the group.

Amsterdam's $307.60 ADR is 82% higher than Lisbon's $169.20, despite Amsterdam hosting fewer than half the listings. Barcelona's $26,510 median annual revenue leads all five markets despite facing the most existential regulatory threat.

The pattern reflects a fundamental economic principle: supply compression drives price. When regulation removes non-compliant or casual listings from a market, the remaining compliant supply absorbs demand at higher rates. Berlin's experience confirms this at the housing level -- enforcement of the Zweckentfremdung law returned approximately 8,000 apartments to the long-term housing market, removing supply from the STR pool and concentrating demand among remaining operators.

This does not mean regulation is painless. Oxford Economics' estimate of EUR 269 million in lost Amsterdam host earnings captures the aggregate impact. Individual hosts who cannot operate within night caps lose revenue entirely. But for compliant, professionally managed properties, the data suggests regulation creates a competitive moat that supports premium pricing.

Key takeaway: Regulation does not eliminate STR revenue -- it redistributes it from non-compliant to compliant operators and compresses supply in ways that support higher per-night rates.

The Atlantic Preview: What EU Rules Signal for US Markets

US cities are watching Europe's regulatory evolution closely. The architectural parallels are clear, but the approaches differ in important ways.

NYC's Local Law 18 represents the aggressive end of the spectrum. Since its enforcement began in September 2023, Airbnb listings dropped from approximately 38,000 to roughly 3,000 -- a 90%+ reduction. The economic impact has been severe: an estimated $2.5 billion in lost visitor spending citywide, 21,000 affected jobs, and a $96 million tax revenue shortfall. Hotel ADR rose 6% year-over-year in response.

The EU framework is architecturally different from all of these. Rather than creating near-bans (NYC) or blunt residency requirements (Sacramento), the EU standardizes enforcement infrastructure while leaving substantive restrictions to local authorities. This layered approach allows graduated responses: a 120-night cap in Paris, a 30-night cap in Amsterdam, a license phase-out in Barcelona -- each calibrated to local conditions, all enforced through the same data-sharing infrastructure.

The Compliance Checklist: What Hosts Must Do Before May 20, 2026

For hosts and investors operating STR properties in Europe, here are the concrete steps required before the May 2026 deadline:

1. Verify registration status -- Confirm whether your property's jurisdiction requires registration. Check the national authority website for your country (Spain's NRUA, France's national portal, Italy's BDSR database, Greece's AADE system).

2. Obtain your registration number -- Apply through the local competent authority. Timelines vary: Spain is already live (EUR 27 fee), Italy CIN is mandatory since January 2025, France's national portal launches May 2026.

3. Display the number everywhere -- Add the registration number to all platform listings (Airbnb, Booking.com, Vrbo) and, in Italy, to the physical exterior of the property. Non-display fines range from EUR 800 (Italy) to EUR 10,000 (Paris).

4. Track night counts per property -- If your jurisdiction imposes a night cap (Paris: 120, Amsterdam: 30), implement a tracking system. Platforms will auto-block in some cases, but you are ultimately responsible for compliance.

5. Reconcile tax obligations -- Review your tax status in each jurisdiction. Italy's cedolare secca applies at 21% for the first property and 26% for additional ones. Greece cross-references platform data with tax filings. Multiple properties may trigger business registration requirements.

6. Prepare audit-ready documentation -- Maintain records of all bookings, guest identities (Italy requires visual verification), registration correspondence, and tax filings. The EU's data-sharing framework means authorities can now request specific records backed by platform-reported data.

7. Classify properties by regulatory resilience -- Assess each property against its local regulatory trajectory. A licensed Barcelona property has value through 2028 but no renewal path. An Amsterdam primary residence operates within a 30-night constraint. A Florence property faces a lighter regime but rising tax rates.

8. Monitor enforcement developments -- Amsterdam's proposed reduction from 30 to 15 nights (April 2026), Italy's proposed 26% flat tax standardization, and Greece's expanding permit restrictions are all pending.
