The EU New Short-Term Rental Transparency Law Takes Effect May 20. Here Is What Every Host With European Properties Needs to Know.

EU Regulation 2024/1028 takes effect on May 20, 2026, and it requires every short-term rental host operating in the European Union to obtain a unique registration number from a national authority. If you do not have one by that date, platforms like Airbnb, Booking.com, and Vrbo are required to delist your property. Yes, “required” (as in, it is not a suggestion, and the platforms have every reason to comply given what just happened to Airbnb in Spain).

If you are a US-based investor or host with European STR properties, this is the article you need to read before May 20. If you are considering entering the EU market, this is the regulatory landscape you are walking into.

This article provides general information and should not be construed as legal advice. Consult a qualified attorney in your jurisdiction for advice specific to your situation.

What EU Regulation 2024/1028 Actually Does

Let me translate the bureaucratic language into plain English. The regulation entered into force on May 19, 2024, with a 24-month transition period. That transition period ends May 20, 2026. From that date forward, three things happen simultaneously across all 27 EU member states:

First, every host must register. If your country or municipality has a registration procedure (and virtually all of them do or will by May), you must obtain a unique identification number through that local system. This number must appear on every listing, across every platform.

Second, platforms must validate. Airbnb, Booking.com, Vrbo, and every other online STR platform operating in the EU must verify that your registration number is valid before your listing goes live. Non-compliant listings face mandatory removal. This is not a “best effort” standard. The regulation uses the word “shall.”

Third, platforms must share data. Every month, platforms transmit standardized activity data to each member state’s Single Digital Entry Point (the SDEP, which I will explain below). This data includes your identity, your property address, your listing URLs, the number of nights booked, and the number of guests. Smaller platforms report quarterly instead of monthly.

What This Regulation Is Not

I want to be clear about what Regulation 2024/1028 does not do, because I have seen a fair amount of confused commentary conflating this with local restrictions.

This regulation does not ban short-term rentals anywhere in the EU. It does not impose EU-wide night caps (Paris’s 90-day limit and Amsterdam’s 30-night cap are local rules, not EU mandates). It does not replace or override local licensing, zoning, or tourist tax requirements. It does not create an EU-wide STR license.

What it does is build the data infrastructure that allows local authorities to actually enforce the rules they already have on the books. Think of it as the plumbing, not the water pressure. Local governments decide the rules. This regulation makes sure the platforms hand over the data that makes those rules enforceable.

The Architecture: How Data Flows From Your Listing to Local Authorities

Understanding the data architecture helps you understand why this regulation has teeth. Here is how it works:

Step 1: Host registration. You register with your national or municipal authority. You provide personal or business identification, the property address (including floor and unit number), maximum guest capacity, whether the property is a primary or secondary residence, and your tax identification. You receive a unique registration number.

Step 2: Platform validation. When you enter that registration number on Airbnb (or any platform), the platform checks it against the national registration database. If the number does not match, your listing does not go live. If it was previously live and becomes invalid, the platform must remove it.

Step 3: SDEP data collection. Each member state builds a Single Digital Entry Point. This is the national gateway that receives standardized data from every platform operating in that country. Platforms transmit monthly reports covering host identity, property details, listing URLs, nights booked, and guest counts.

Step 4: Local enforcement. The SDEP distributes relevant data to local competent authorities (the municipality, the tourism office, the tax authority). Those local authorities can now cross-reference platform activity against registration databases, tax filings, and local rules like night caps or zoning restrictions.

The practical effect: if you are renting your Paris apartment for 120 nights when the local limit is 90, the city no longer needs to conduct manual surveillance to catch you. The data arrives automatically, every month, from the platforms themselves.

Country-by-Country Overview for US Investors

The regulation applies across all 27 EU member states, but not every market is equally relevant to US-based STR investors. These five countries represent the most active regulatory environments and the markets where American investors are most likely to hold properties.

France

France has one of the most developed STR regulatory frameworks in Europe. Every host must register and receive a 13-digit registration number (a 5-digit INSEE commune code plus 8 digits) through their local municipality. This number must appear on all listings.

In Paris, primary residences can be rented for a maximum of 90 days per year. Secondary residences require a formal change-of-use authorization from the city, which is notoriously difficult to obtain. France recently added energy performance requirements: new STR listings must have a DPE (diagnostic de performance energetique) rating between A and E. Properties rated F or G are prohibited from short-term rental use.

Penalties are substantial. Failure to register can result in fines up to EUR 10,000. Exceeding the rental night cap carries fines up to EUR 15,000. Failure to remove an unlawful listing can reach EUR 50,000.

For US investors: France’s system is mature and will integrate smoothly with the EU regulation’s requirements. If you own a property in Paris, Lyon, or Bordeaux, you should already have a registration number. If you do not, start the process immediately.

Spain

Spain is the most aggressive enforcement environment in Europe right now. In late 2025, Spanish authorities levied a EUR 64 million fine against Airbnb for hosting tens of thousands of illegal listings. A Madrid court refused to suspend the fine in March 2026, meaning Airbnb must pay while its appeal proceeds. Authorities calculated the penalty at roughly six times the profits Airbnb earned from the non-compliant inventory.

Registration requirements vary by autonomous community (Spain’s equivalent of states). Catalonia, the Balearic Islands, Andalusia, and the Canary Islands all have established registration systems. Barcelona has been particularly aggressive, phasing out tourist apartment licenses in residential areas.

For US investors: Spain’s enforcement posture makes compliance non-negotiable. If you have a property in Barcelona, Madrid, Malaga, or the Balearic Islands, verify your registration status now. The EUR 64 million Airbnb fine was a platform enforcement action (Meredith Lane covered that story here). Regulation 2024/1028 creates the infrastructure to prevent that type of non-compliance from recurring at scale.

Italy

Italy launched its national CIN (Codice Identificativo Nazionale) system on January 2, 2025, ahead of the EU regulation’s May 2026 deadline. Every STR host must register through the BDSR portal (Banca Dati Strutture Ricettive), the national database managed by the Ministry of Tourism. The CIN must be displayed both on your online listings and physically at the property.

Failure to display the CIN carries fines ranging from EUR 500 to EUR 5,000. Operating without a CIN can result in fines up to EUR 8,000 and platform delisting. Italy’s CIN system is expected to integrate directly with the EU regulation’s registration framework, meaning Italian hosts who already have a CIN are well-positioned for May 20 compliance.

For US investors: if you own property in Rome, Florence, Milan, or along the Amalfi Coast, the CIN system is already live. Register through the BDSR portal if you have not already. Italy is ahead of most EU countries on implementation.

Portugal

Portugal overhauled its Alojamento Local framework in November 2024 with Decreto-Lei n.o 76/2024. Registration is conducted through the Balcao do Empreendedor online portal and managed at the municipal level. Upon approval, hosts receive an RNAL number that must appear on all listings and promotional materials.

Lisbon has implemented containment zones based on AL density thresholds, suspending new registrations in certain freguesias (parishes) where STR density exceeds local caps. A positive development for existing license holders: AL licenses are now transferable when a property is sold, and the previous automatic expiry rule has been abolished.

Lisbon charges EUR 4 per person per night in tourist taxes, which hosts must collect and remit.

For US investors: Portugal’s system is well-established, but Lisbon’s containment zones mean that new market entry in central Lisbon may be restricted. If you already hold an AL license, the good news is that it is now transferable and does not expire. Porto and the Algarve region have less restrictive registration environments.

The Netherlands

Amsterdam operates one of Europe’s strictest STR frameworks. Primary residences can be rented for a maximum of 30 nights per year, with proposals in some zones to reduce that cap to 15 nights in 2026. Hosts must register with the municipality and obtain a registration number.

The EU regulation’s monthly data reporting will give Amsterdam (and other Dutch municipalities) granular visibility into whether hosts are exceeding their night caps. Previously, enforcement depended on complaints and periodic audits. Now, platform-reported data will flow directly to the SDEP every month.

For US investors: the Netherlands, and Amsterdam in particular, is one of the most restrictive STR environments in Europe. The 30-night cap (potentially dropping to 15 in some areas) makes it difficult to generate meaningful revenue from a primary residence listing. Understand the local rules thoroughly before investing.

What You Need to Do Before May 20

Here is a practical checklist for US-based hosts with EU properties. I am keeping this action-oriented because you have 49 days.

1. Identify your registration authority. Registration is handled at the national or municipal level, depending on the country. In France, it is your local mairie (city hall). In Italy, the BDSR portal. In Portugal, the Balcao do Empreendedor. In Spain, your autonomous community’s tourism authority. Find the correct authority for your property’s location.

2. Gather your documentation. You will generally need proof of property ownership or authorization to operate, personal identification (passport for non-EU nationals), tax identification in the host country, the property’s exact address including floor and unit number, and information about maximum guest capacity.

3. Submit your registration application. Most countries offer online registration portals. Processing times vary. France and Italy have relatively quick turnaround if your documentation is in order. Spain and Portugal may take longer depending on the municipality. Do not wait until May to start this process.

4. Receive and display your registration number. Once issued, your registration number must appear on every listing across every platform. In Italy, it must also be displayed physically at the property. Update your Airbnb, Booking.com, and Vrbo listings immediately.

5. Verify your listings are platform-compliant. After May 20, platforms will begin validating registration numbers against national databases. If your number does not check out, your listing faces removal. Make sure the number you entered matches exactly what was issued (watch for typos, extra spaces, or formatting differences).

6. Understand your local rules. The registration number is the floor, not the ceiling. You still need to comply with local night caps, zoning restrictions, tax obligations, insurance requirements, and safety standards. Registration does not equal a blanket license to operate. It means the authorities now have the data infrastructure to verify that you are following the rules.

7. Set up your record-keeping. Platforms will be reporting your booking data monthly. Keep your own records of guest check-ins, nights booked, and revenue generated. If there is ever a discrepancy between what the platform reports and what you report to tax authorities, you want your own documentation to reference.

The Bigger Picture: Why This Regulation Has Real Teeth

Picture this: you are a US investor who bought a vacation property in Barcelona three years ago. You have been listing it on Airbnb, collecting solid rental income, and your local property manager handles everything. You have a registration number (probably), your reviews are great, and life is good.

Then May 20 arrives. Your property manager mentions something about new EU requirements. You assume it is just more bureaucracy (I have reviewed more regulatory frameworks than most people have streaming subscriptions, and I understand the instinct to tune out). But here is what changes.

Before May 20, enforcement depended on local authorities actively investigating non-compliance. They had to go looking for you. After May 20, your platform reports your activity data every single month. Your identity, your address, your booking volume. It flows automatically from Airbnb to Spain’s SDEP, which distributes it to your local authority in Barcelona. If your registration is expired, or your property is in a zone that no longer permits STRs, or you are exceeding a night cap, the authorities do not need to find you. The data finds them.

The EUR 64 million Airbnb fine in Spain illustrates the enforcement direction. That fine targeted the platform for hosting illegal inventory. Regulation 2024/1028 shifts the infrastructure so that the data makes non-compliance visible before fines become necessary. It is preventive plumbing, not reactive punishment.

For Investors Considering EU Market Entry

If you are a US-based investor considering your first European STR property, the timing of this regulation actually works in your favor in one important respect: the rules are becoming clearer.

Before Regulation 2024/1028, STR regulations in Europe were a patchwork of local, regional, and national rules with inconsistent enforcement. You could technically operate in a gray area in some markets because enforcement was spotty. That gray area is closing.

The upside is that a transparent, standardized regulatory environment benefits legitimate operators. If you are willing to register properly, comply with local rules, pay your taxes, and operate professionally, you have less to worry about from unlicensed competitors who previously undercut you on price because they were not paying registration fees or tourist taxes.

Markets to watch: Portugal’s Algarve and Porto offer relatively accessible entry points with established registration systems. Italy’s smaller cities (outside Rome and Florence) have less restrictive environments. France outside of Paris has more flexibility, particularly in resort areas and the south.

Markets to approach carefully: Barcelona (active license phase-out), Amsterdam (30-night cap potentially dropping to 15), and central Lisbon (containment zones restricting new registrations).

The regulatory landscape for US-based hosts is shifting rapidly too. International investors should keep an eye on both sides of the Atlantic.

The Bottom Line

EU Regulation 2024/1028 is not a ban. It is not a cap. It is data infrastructure. But data infrastructure with mandatory platform compliance is arguably more powerful than either of those things, because it makes every local rule enforceable at scale.

If you have EU properties, get registered before May 20. If you are already registered, verify that your number is correctly displayed and that your platforms have validated it. If you are considering EU market entry, understand the registration requirements of your target country before you close on a property.

The hosts who treat this as just another layer of bureaucracy (and yes, it is another layer) and comply proactively will be fine. The hosts who ignore it risk waking up on May 21 to find their listings gone.

We do our best to keep our regulatory guides accurate and up to date, but ordinances change and we are only human. Always verify current requirements directly with your local municipality before making business decisions.
