The short answer
Two things happened in the last year that between them make most of the English-language advice about Spanish rental legality out of date. In August 2025 Madrid's Plan RESIDE came into force, and it does not restrict tourist flats in residential buildings in the historic centre so much as end them. In May 2026 Spain's Supreme Court struck down the national rental register that had been introduced the previous summer, on the grounds that the State had no competence to create it.
The practical effect for someone booking a week in Madrid is narrower than either headline suggests, and it is worth stating plainly before the detail. You are not the one breaking the law, and you are not the one who gets fined. Enforcement in Madrid is aimed squarely at operators. Your exposure is a cancellation, not a penalty. But cancellations are exactly what a squeezed market produces, and central Madrid is now a squeezed market, so the question is worth ten minutes.
The useful version of that ten minutes is not the one you will read elsewhere. Almost every guide tells you to check the licence number in the public register. In the Comunidad de Madrid there is no public register you can search, which makes that advice unactionable. What follows is what you can actually do instead.
One disclosure first, because it bears on how you should read the rest. This site earns a commission when you book through our links, and the properties we curate are overwhelmingly the licensed, whole-building operators that this regulation favours. That is a real conflict of interest and you should weigh it. It is also, as it happens, the finding: the rules have pushed compliant supply toward exactly that kind of operator, and our own curation is a measurement of how far. How we make money.
What changed in May 2026
In December 2024 Spain created a single national register for short-term and seasonal rentals by royal decree, and from 1 July 2025 a national registration number became a prerequisite for advertising a property on a booking platform. For about eleven months this was the headline compliance fact in every article written about Spanish holiday lets, and a great many of those articles are still online, still confidently describing a requirement that no longer exists.
On 21 May 2026 the Contentious-Administrative Chamber of the Supreme Court, ruling on an appeal brought by the Generalitat Valenciana, annulled it. The reasoning was competence rather than policy: tourism and housing are matters for the autonomous communities, the communities already run their own rental registers, and the State could not layer a mandatory national register on top of them. The judgment is 620/2026.
What survived matters as much as what fell, and this is the part most summaries get wrong. The Court upheld the appeal only in part. The Ventanilla Unica Digital de Arrendamientos, the digital single window, was not annulled. Nor were the obligations on platforms such as Airbnb and Booking to transmit data about their listings, nor the provisions covering data transfer for statistical purposes. So the reporting architecture stands and the national licence number does not.
For a traveller, the takeaway is a small but genuinely useful piece of scepticism. If a page tells you to verify a Spanish rental by its national registration number, that page has not been updated since May 2026, and you should discount everything else it says about compliance accordingly. Regional numbers, including Madrid's, were never the thing that was struck down and remain exactly as relevant as they were.
Madrid asks for two permissions, not one
This is the single most misunderstood point about Madrid specifically, and it catches professional operators out, never mind guests.
A tourist dwelling in Madrid needs two separate authorisations from two different levels of government. The first is the CIVUT, the certificate of suitability for tourist-use dwellings, which sits at Comunidad de Madrid level and has been required since 2019. It is a technical document prepared by an accredited professional, and it covers habitability and safety: evacuation plans for the dwelling and the building, safety measures, the state of the installations, and detailed measurements including ventilation openings. The second is a municipal planning licence from the Ayuntamiento de Madrid, which is a land-use question rather than a safety one, and which asks whether this use is permitted in this building at all.
The two are routinely conflated, including by hosts acting in good faith. A CIVUT on its own does not make a flat legal to operate. A host who answers a legality question by naming their CIVUT and stopping there has answered half of it, and the half they have skipped is the half Plan RESIDE tightened.
Plan RESIDE, and why the centre is different
Plan RESIDE was approved by Madrid City Council in May 2025 and definitively adopted that August. It is an urban-planning instrument rather than a tourism one, which is why it bites harder than the tourism rules that preceded it: it does not regulate how a tourist flat operates, it decides where the use is permitted to exist.
Inside the historic centre, the almendra central, the rule is close to absolute. Licences are not granted for dispersed tourist dwellings in residential buildings, not even on the ground floor. The use is confined to buildings that are entirely tourist or tertiary in character. A flat on the third floor of a residential block in Sol or Malasana is not a borderline case under this plan. It is outside it.
Outside that perimeter the plan is restrictive rather than prohibitive. A tourist dwelling in a residential building is permitted only with independent access from the street, and only on the ground or first floor. In practice that describes a small and specific fraction of Madrid's housing stock, which is the intent.
The enforcement regime was rebuilt at the same time, and the numbers are the part worth remembering. Where the previous sanction ceiling was in the region of 3,000 euros, the current scheme escalates: a cease order, then a first firm sanction of 30,001 euros, then 60,001 euros if the activity continues, then 100,001 euros if it persists. Because they accumulate, the figure quoted in the press as the maximum, around 190,000 euros, is the sum of a sequence rather than a single fine. That distinction is worth holding onto, because the headline number is often repeated as though one infraction produces it.
It is working, in the sense that it is changing behaviour. The city has reported hundreds of illegal tourist dwellings returned to residential use, and the stock of registered tourist flats across the Comunidad de Madrid has fallen by roughly a sixth since the plan took effect. Whatever one thinks of the policy, it is not decorative.
The register you cannot search
Here is where the standard advice fails, and it is worth being blunt about it because the advice is repeated everywhere.
Madrid registration produces a code beginning VT followed by a number, assigned after a declaration of responsibility and supporting documents. Both the host and the platform are expected to make that number available to you. So far, so conventional.
But the Comunidad de Madrid does not publish a public search tool where you can type a VT number and see what comes back. There is no lookup page, no downloadable list, no self-service verification. The number you are given is therefore an assertion, and for a traveller sitting at a laptop the day before booking, it is an assertion that cannot be independently confirmed in the way the phrase "check the register" implies. You can approach the regional tourism authority directly, and that is a real route, but it is a piece of correspondence rather than a click.
We think that is worth saying out loud rather than repeating advice that does not work. It also reframes the question usefully. If the number cannot be checked, then the number is not the test. The building is the test, because Plan RESIDE is a rule about buildings, and the building is something you can see.
What to ask, and what a good answer sounds like
One message, before you book, and the phrasing matters less than the specificity. Four things.
Is the building entirely tourist or tertiary use, or is it a residential block with private homes in it? This is the question Plan RESIDE actually turns on, and for a central Madrid address it is close to dispositive. An operator running a whole building will answer it immediately and often with a degree of pride, because it is their commercial position. Hesitation here is the signal.
Do you hold both the CIVUT and the municipal licence? Named separately, because that is how you find out whether the host knows they are two things.
What is the VT registration number? You cannot verify it yourself, but asking establishes whether one exists and produces something in writing.
If the property cannot host me, what happens? The most practical question of the four and the one almost nobody asks. You are looking for a rehousing commitment or a clear refund position.
A good answer is specific, fast, and volunteers the distinction between the two permissions before you press on it. A poor answer is a reassurance without a noun in it. You are not conducting an audit and you will not get certainty; you are sampling how this operator handles a question they should find easy, which is a reasonable proxy for how they will handle a problem at eleven at night.
What actually happens to a guest
Worth stating clearly, because the fine figures above are alarming and they are not aimed at you. The sanctions regime targets the operator. A guest who books a flat that turns out to be unlicensed has not committed an offence and is not exposed to the 30,001 euros or anything like it.
The real risk is duller and more likely: a cancellation, possibly close to arrival, in a city where the compliant central supply is thinner every quarter. That is a logistics problem rather than a legal one, and it is solved by the ordinary defences. Book through a platform that carries a cancellation and rehousing policy. Pay by a method that leaves you a chargeback route. Keep the correspondence. And treat an unusually cheap central flat in a plainly residential building as the market telling you something about risk rather than offering you a bargain, because under the current plan that is often exactly what it is.
Why almost everything we list is an aparthotel
We did not set out to make a regulatory point. We set out to curate the best short-stay options in eight central barrios, and we published what we found. But the shape of what we found is itself evidence, so here it is with the numbers attached.
We currently curate 51 properties across eight barrios. Almost none of them is a flat in a residential building. They are serviced-apartment and aparthotel operators running whole buildings: the category Plan RESIDE explicitly leaves the door open to. Nine operators account for 24 of the 51, close to half the set, with Limehome at five properties and Numa at four. That concentration is not a curation preference. It is what central Madrid's compliant short-stay inventory now largely consists of.
The scarcity shows up more sharply at the barrio level, and this is the finding we did not expect. When we ran an exhaustive sweep to top up our thinnest barrios, we found that Lavapies and Retiro were not under-searched but exhausted: 17 of 19 and 18 of 19 available results respectively were already on the site. We could not reach our own advertised floor of six properties in either, not because we had not looked hard enough, but because the inventory of this type does not extend that far. Our Retiro and Lavapies pages carry three and four properties, and they say so.
Read alongside the regional stock falling by roughly a sixth, the picture is coherent. Regulation has not removed short-stay accommodation from central Madrid. It has consolidated it into professional operators with whole buildings, and it has made the boutique version of it, the individual flat in a residential block, considerably harder to find and considerably more likely to be operating outside a licence.
We should say what this evidence is not. It is a census of one commercial inventory on one booking platform, filtered by our own selection criteria, and it is not a study of Madrid's housing market. We have also not verified a single licence number for a single property we list, and nothing on this site should be read as a statement that a named property is compliant. That is a claim only the operator and the administration can make.
What is still unsettled
Anyone telling you this area of law is settled is not following it. Two live threads.
Plan RESIDE is under challenge. More than a hundred tourist-flat owners filed a contentious-administrative appeal against it at the Tribunal Superior de Justicia de Madrid in November 2025, and a separate appeal from the Socialist municipal group has also been admitted. The TSJM declined to suspend the plan as an interim measure, so it remains in force, but the substantive question of its legality is still before the court. Individual sanctions have also been overturned on appeal. The plan is operative and contested at the same time, and those are not contradictory.
The national picture may be rebuilt. The Supreme Court struck down the national register on competence grounds rather than on principle. That is the kind of defect that legislation can be redrafted to cure, and the digital single window that survived the judgment is the natural foundation for a second attempt. Nobody booking a trip needs to track this. Anyone relying on this page a year from now does.
Which is the honest closing note. We will re-check this page against the sources below and restate the date when we do. If the date at the top has aged badly by the time you are reading, treat the specifics as a starting point and confirm the current position with the Comunidad de Madrid and the Ayuntamiento de Madrid directly.
Sources and review date
This page describes the regulatory position as we understand it in August 2026. It is written for travellers deciding where to book, and it is not legal advice. Anyone operating a property, rather than staying in one, should take professional advice, because the consequences described above fall on them and not on their guests.
The load-bearing sources are the Supreme Court's judgment 620/2026 of 21 May 2026 and the Consejo General del Poder Judicial's announcement of it; Royal Decree 1312/2024, which created the register that judgment annulled; the Ayuntamiento de Madrid's own material on Plan RESIDE and on its enforcement plan for tourist dwellings; and the Comunidad de Madrid's tourist-dwelling pages covering the CIVUT and VT registration. Reporting from Spanish outlets covering the TSJM appeals and the sanction figures was used for the litigation status and the enforcement numbers.
Last reviewed August 2026. Next scheduled review: with our quarterly curation recheck. Rules, figures and litigation status all change, and this page advances only when someone has actually re-read the sources.
If you want the practical companion to this, our rental versus hotel guide covers why the aparthotel middle is where most of Madrid's good answers now sit, which is the commercial consequence of everything described here. Our long-stay guide is the one to read if your booking runs past a month, because the rules that apply to it are different again.
