Home » Spain’s new tourist rental registry validates 8,800 properties in just three months, eyes thousands more

The Government’s new centralised registry for short-term and tourist rentals is off to a busy start — but it also reveals the scale of the rental wild west authorities are trying to rein in.

Three months after its launch, Spain’s new Ventanilla Única Digital (Single Digital Window) has already validated nearly 8,800 homes for short-term or tourist rental. These properties now possess an official registration number — a kind of vehicle plate for holiday lets — which will soon be mandatory for advertising on platforms like Airbnb or Booking.com.

In total, the platform has received more than 18,000 registration requests so far. That means slightly less than half have already been approved, while about 7,400 applications remain under review. However, not all properties have made the cut — 1,924, or 11% of requests, were denied, typically for failing to meet regulatory requirements.

July deadline looms for online listing

From July onwards, platforms will be obliged to display each property’s unique ID number in listings — or face penalties. That puts the pressure on thousands of unregistered landlords to get their paperwork in order, fast.

The registry was developed by the Ministry of Housing, led by Isabel Rodríguez, to offer a centralised, electronic process for landlords to legitimise their short-term lets under national, regional, and local regulations. Applications must include detailed property information such as the cadastral reference, rental modality (entire home, individual rooms, etc.), and occupancy limits, among other details.

A first in the EU, but more to come

Spain’s tourist rental registry is the first of its kind in the European Union, created in response to regulations laid out by Brussels in early 2023. The EU-wide objective is to create a network of national platforms that will eventually feed into a continental system before mid-2026.

Officials hope centralised oversight will bring a more “transparent, safe, and reliable” rental market — and help curb widespread abuse of tourist rental laws, which have frustrated long-term housing advocates and local governments alike.

Illegal rentals still rampant in Madrid

Despite the progress, enforcement remains patchy. Spain’s Consumer Affairs Ministry has separately flagged over 15,200 allegedly illegal tourist properties operating in Madrid alone — and has formally requested that the city’s mayor, José Luis Martínez-Almeida, remove those listings from online platforms. The move underscores an ongoing disconnect between detection efforts and sanctions at the municipal level.
