Does the Rental Registration Number (NRU) block short-term tourist rentals? Legal key points
The introduction of the Rental Registration Number (NRU) has brought a new layer of control to the short-term tourist rental market and to non-tourist short-term lets. Conceived as a tool for oversight and transparency, its purpose is clear: to ensure the proper identification of properties and to strengthen control over their use, particularly on digital platforms.
This new framework for short-term tourist rentals has its origin in Regulation (EU) 2024/1028, which establishes the need to improve oversight of short-term lets across the European Union. In Spain, it has been implemented through Royal Decree 1312/2024, which regulates the obligation to register properties intended for these types of lettings.
However, in practice the implementation of the new regulation was perceived as operationally abrupt, both by citizens and by staff at the various Land Registries, as no investment was made in any form of information campaign. In addition, the capacity of many registries was not prepared for the surge of applications submitted in the short-term tourist rental sector.
Rather than providing legal certainty, the Rental Registration Number is generating significant difficulties for owners, operators and real estate asset managers. In particular, the lack of regulatory clarity and the diversity of criteria in its application are giving rise to situations of uncertainty that directly affect the viability of operations in the short-term tourist rental sector.
The Royal Decree establishes the obligation to register, but does not precisely define the technical and documentary requirements necessary to obtain the corresponding number. Nor does it clearly delimit the scope of the administrative review or the specific effects of a potential negative assessment in the context of short-term tourist rentals.
Moreover, the aforementioned Royal Decree is a piece of national legislation, while the requirements for obtaining the Rental Registration Number, as well as municipal and regional licences, often give rise to conflicts between regional and national regulations, particularly in relation to short-term tourist rental properties.
In practice, this lack of detail results in inconsistent assessments in the short-term tourist rental market.
The Land Registry in short-term tourist rentals: a decisive role
One of the most significant, and at the same time most problematic, elements in obtaining a Rental Registration Number for short-term tourist rentals is the need to properly evidence the identification of the property: dwellings that remain registered as commercial premises despite the fact that the local authority has already granted a change of use, undeclared new-build works, or properties recorded as under construction (even though their construction was completed years ago).
In practice, this implies a direct link to the registered description of the property, which in many cases requires the existing information to be reviewed, supplemented or clarified.
In addition, significant issues arise from the interpretation of the articles of association of homeowners’ associations, which has fallen to the registrars, leading to constant intervention by the Directorate General and, consequently, delays in short-term tourist rental transactions.
The problem arises when this requirement is not applied uniformly, as there is still no established doctrine and there is a clear disparity of criteria between registries.
Lack of uniformity in short-term tourist rentals: freedom of interpretation
The absence of consistent criteria in the application of the Rental Registration Number is leading to a genuine freedom of interpretation in the short-term tourist rental sector. As a result, properties with substantially identical characteristics may obtain different outcomes depending on the competent registry.
This lack of uniformity directly affects legal certainty. Operators in the short-term tourist rental market face a scenario in which it is not possible to predict with certainty the outcome of an application, even when all requirements are met.
In this context, obtaining the Rental Registration Number ceases to be a regulated procedure and instead becomes a process in which documentary strategy and the proper structuring of information play a key role.
Consequences of the Rental Registration Number in short-term tourist rentals for owners and operators
The difficulties described are not merely theoretical. In practice, they are generating significant effects on the operation of the short-term tourist rental market and short-term lettings more broadly.
Firstly, there are significant delays in obtaining the Rental Registration Number, which may prevent or postpone the use of properties intended for short-term tourist rentals.
Secondly, the need to adapt documentation—whether through more detailed technical certificates or by means of supplementary deeds—entails increased costs and delays.
Particularly problematic is the situation of those properties that have all the necessary licences but are unable to obtain a Rental Registration Number due to registry or documentary issues. In such cases, assets that are otherwise fully viable for short-term tourist rental may become effectively blocked.
Moreover, the duplication of controls is a matter of debate, given that the Autonomous Communities have already carried out a prior review for their registration.
How can we address legal uncertainty in the short-term tourist rental sector?
In this scenario, it is essential to adopt a proactive approach in the short-term tourist rental sector.
First, it is essential to carry out a prior review of the property’s registration status, identifying any inconsistencies that may affect its use for short-term tourist rentals.
Secondly, coordination between technical and legal elements is key. The documentation must be consistent as a whole.
Finally, where different operators are involved, it is advisable to clearly define contractual responsibilities, particularly in relation to obtaining the Rental Registration Number.
Conclusions
The Rental Registration Number is a relevant instrument in the regulation of short-term tourist rentals, but its current application reveals significant shortcomings that create legal uncertainty.
In this context, the viability of short-term tourist rentals largely depends on the ability to anticipate how the rules will be applied and to structure the documentation properly.
Experience shows that success in obtaining the Rental Registration Number does not depend solely on regulatory compliance, but on the proper alignment of registration, technical and administrative elements.
For this reason, specialised legal advice in the short-term tourist rental sector is essential to avoid obstacles and ensure the profitability of assets.
