The Ministry of Housing and Urban Agenda has recently launched the draft Royal Decree for the creation of the Digital Single Window for Rentals. This regulation aims to improve the regulation of short-term rentals and combat fraud in the sector, establishing a mandatory registration system that affects both property owners and online platforms.
This measure is particularly relevant in high-demand cities like Barcelona, where temporary rental (also known as seasonal rental or short stay rental) has become a common alternative for both private owners and tenants who need housing for work, academic, or personal reasons.
In fact, the rise of temporary rental Barcelona private has led to an increase in listings on digital platforms, prompting the Administration to strengthen controls to prevent fraud, hidden contracts, and unregistered properties operating outside the law.
Who does the regulation affect?
This new decree has two main groups of affected parties:
- Online platforms: From giants of vacation rentals like Airbnb to small real estate agencies that post short stay offers online, all must include in their listings the registration number assigned to each property.
- Owners and hosts: All those who offer short stay rental services in Spain will be required to register their properties starting January 1, 2025. This registration will apply to tourist rentals, seasonal rentals, or those of rooms in private homes.
What types of rentals are subject to this regulation?
The regulation governs all short-term rental contracts, including entire homes, rooms, or alternative properties such as ships or vessels rented without navigation purposes. The key to determining if a rental is short-term is the reason behind the rental: if the tenant is not seeking a permanent residence, it is considered a temporary rental.
In practice, this affects very common situations in Barcelona such as:
- Temporary rental for students per semester or university course.
- Seasonal rental for displaced workers (company projects, relocations, expatriates).
- Monthly rental for families who are renovating their primary residence.
- Room rentals in private homes for short periods.
- Tourist vacation rental with frequent guest turnover.
The key is that the contract is justified as temporary and not as a primary residence. Therefore, it is advisable to properly document the reason for the stay to avoid future problems in case of inspection.
How is the registration number obtained?
Starting in January 2025, property owners must go to the property registry to request a registration number that identifies their rented unit. This number must appear in all online listings and will be necessary for any type of marketing. The registration process includes a data verification, which can take up to 15 days, and in case of error, owners will have a period of seven days to correct the incorrect information.
As a professional recommendation, it is important for the owner to have the basic information of the property prepared in advance: cadastral reference, registration data, exact address, permitted use, and documentation proving ownership. In many cases, the delay does not come from the process itself, but from inconsistencies between the Cadastre, Registry, and the information that appears in online listings.
Additionally, if we are talking about temporary rental in Barcelona by individuals, it is advisable to check if the homeowners’ association has internal limitations or agreements that may affect tourist use or short-stay activity.
What does it imply for rental platforms?
Online platforms are required to include the registration number of each property in their ad publication systems. If they do not, they may face penalties. This control will be vital to combat fraud and ensure that only legally registered properties are offered for short-term rental.
What happens if the registration number is not obtained?
If an owner does not have the registration number, they will not be able to market their property on online platforms, and if an incorrect registration number or one associated with another type of rental is used, it will also be considered illegal. The lack of this number could result in financial penalties and the prohibition of continuing to advertise the property.
From a real estate perspective, this point is key: many platforms will not only remove listings without registration, but they could also block accounts or prevent the posting of new properties until the situation is regularized. This will directly affect owners who depend on this income, especially in high turnover areas like Eixample, Poblenou, Gràcia, or Sant Martí.
Therefore, if your property is intended for seasonal rental in Barcelona, it is advisable to act in advance to avoid losing the ability to market it just during high-demand months.
Validity and renewal of the registration number
The registration number will be valid for 12 months and can be renewed if leases are established during this period. To request the extension, it will be necessary to present a list of the leases made, including the reason that justifies the tenant’s need for temporary housing.
What does it mean for owners?
Owners of properties that are rented out for short periods must be prepared to comply with this new regulation. Starting in January 2025, those who do not register will not be able to continue legally renting their properties. Therefore, it is crucial to start the registration process in advance and meet the established deadlines and requirements.
Practical tips if you are doing temporary rental in Barcelona as an individual
If you are an owner and are offering a temporary rental Barcelona individual, here are the points that generate the most problems and that should be reviewed before 2025:
- Well-drafted contract: it must clearly reflect that it is a temporary lease and the reason for the stay.
- Consistent duration: very short repeated contracts may be considered disguised tourist activity.
- Deposit and guarantees: put in writing the security deposit, utilities, inventory, and condition of the property.
- Transparent advertising: the advertisement must match the reality of the property and the rental modality.
- Prepared documentation: simple note, energy certificate, cadastral reference, and registration data.
Proper document management not only avoids penalties but also facilitates renting the property sooner and with higher quality tenants, reducing defaults, conflicts, and excessive turnover.
