Short-term rentals in Spain have evolved from being an emerging phenomenon to becoming a highly regulated sector. The rise of platforms such as Airbnb or Booking has brought investment opportunities but also neighborhood conflicts, urban planning tensions, and increasing regulatory intervention. In 2025, Spain took another step toward a much stricter regulatory framework, requiring owners and investors to thoroughly understand the legal requirements before placing a property on the tourist market. These include the introduction of the National Register of Tourist Use Housing (N.R.A.), the requirement of the Unique Registry Code (CRU), and the reform of the Horizontal Property Act (LPH).
In this article, we will examine in detail the main legal aspects you must consider if you want to rent out your home for tourism purposes or invest in this sector in Spain.
Differences Between Seasonal Contracts and Tourist Rentals: Two Distinct Legal Realities
Although both share a temporary nature, their purpose is what draws the dividing line, and this determines that their regulation is different:
- Seasonal contract: regulated by the Urban Leases Act (LAU, Article 3.2). It is intended to cover a specific housing need that does not involve permanent residence or a tourist purpose but rather addresses temporary needs (a relocated worker, a student, or a medical treatment). The objective cause of the temporary stay must be justified.
- Tourist rental (Article 5.e LAU): expressly excluded from the LAU and subject to regional sectoral regulations. It applies when a furnished and equipped dwelling is temporarily rented for vacation or leisure purposes and marketed through tourist channels. Example: a listing on Airbnb.
The Supreme Court (for instance, in its rulings of November 30, 2005, and July 3, 2002) has emphasized that what matters is not the label of the contract but the actual use of the property. Signing a seasonal contract while advertising the property on tourist platforms may be considered fraud of law.
Example: Provincial Courts in the Balearic Islands (Rulings No. 95/2023 and No. 41/2022) and Málaga (No. 21/2023) have annulled seasonal contracts that in fact concealed tourist rentals, since the tenant registered residency at the property or successive contracts were signed without a real temporary cause.
The New Requirement of Community Authorization
Organic Law 1/2025, of March 1, has radically changed the rules in horizontal property ownership.
- The new Article 7.3 LPH establishes that the tourist use of a dwelling in a condominium is prohibited unless expressly authorized by the community.
- Article 17.12 LPH states that any authorization, limitation, or prohibition must be approved by a three-fifths majority (60%) of the owners and of participation quotas.
This represents a paradigm shift: previously, renting was allowed unless expressly prohibited; now, prior authorization is required to rent a property for tourist use.
Practical example: in a community of 20 dwellings, at least 12 owners must vote in favor, representing 60% of the quotas.
The community may also approve a surcharge of up to 20% in common expenses for those engaging in tourist rentals. Thus, if the monthly fee is €100, the owner of a tourist apartment could pay €120.
Agreements are not retroactive and therefore do not affect those already legally engaged in the activity, but they are binding for future owners.
Regional Regulation: The Case of Andalusia
Each autonomous community sets its own rules regarding the real estate tourism sector, which requires case-by-case analysis.
In Andalusia, the regulation requires obtaining a Tourist Use Dwelling (VFT) registered in the Tourism Register. Since April 2025, as mentioned, a certificate from the community accrediting express authorization for domestic use of the property is required. And since July 2, 2025, it is mandatory to register the property in the National Register with a Unique Registry Code (CRU).
Minimum technical requirements also exist, including:
- Adequate ventilation.
- Bathrooms in regulatory conditions.
- Basic furniture and equipment.
The National Register of Tourist Use Housing
Since January 2, 2025, there has been a National Register managed by the Association of Registrars. As of July 1, 2025, any property advertised on platforms such as Airbnb or Booking must have a national rental registry number. A unique code (Unique Registry Code, CRU) is issued and recorded in the Property Registry. Registration must be renewed annually using the official form.
This number is independent of the regional one. In other words, owners will need two identifiers:
- The regional one (VFT, VUT, etc.).
- The national one (N.R.A./CRU).
Step-by-Step Procedure to Legally Rent in Andalusia
Andalusia provides a clear example of the complexity of this framework, where the process involves:
- Urban planning check: verifying that the property has a First Occupancy License or a legal planning status.
- Community certificate: obtaining express authorization from the community. Without this document, the license will be denied.
- Compliance with technical requirements: ventilation, bathrooms, equipment.
- Registration in the Andalusian Tourism Register (RTA).
- Registration in the National Register as of July 2, 2025. Without this code, advertising on platforms will be illegal.
Grounds for Denial of Registration
The Property Registry may reject applications in cases such as:
- Community bylaws expressly prohibiting tourist use.
- Properties listed as “under construction” due to the absence of a certificate of completion.
- Discrepancies in the number of rooms or capacity between the regional license and registry information.
- Lack of a regional resolution granting the tourist license.
In these cases, the owner must rectify the situation or will not be able to register the property as a tourist rental.
Tax Obligations of Tourist Rentals
Income derived from tourist rentals must be declared in the Personal Income Tax (IRPF) as real estate capital income, but without the 60% reduction applicable to permanent housing rentals. Non-residents are taxed under the Non-Resident Income Tax.
If no hotel-like services are provided, there is no VAT. However, if the landlord provides hotel industry services (regular cleaning, check-in, breakfast), the Tax Agency considers it a business activity subject to 21% VAT, with the additional obligation to register under the self-employed regime (RETA) in some cases.
Furthermore, platforms are required to submit Form 179 for the transfer of use of dwellings for tourist purposes, which entails greater control by the Tax Agency.
Retroactivity and Protection of Current License Holders
An important aspect is non-retroactivity. Homeowners’ associations cannot retroactively annul a tourist use that already existed and was authorized. Those who held a license before the reform may continue the activity, although they remain subject to current regional rules.
By contrast, new buyers of a licensed property cannot “inherit” it: they must reapply, prove community authorization, and comply with current technical and registration requirements.
Legal Consequences of Non-Compliance
Failure to comply with these rules may lead to serious consequences:
- Civil: cessation action under Article 7.2 LPH, with possible deprivation of property use for up to three years.
- Administrative: fines, which in some regions exceed €10,000.
- Criminal: document forgery (Article 390 of the Spanish Penal Code) if licenses are falsified, or a crime against land planning (Article 319 PC) if renting occurs in areas where tourist use is prohibited by planning regulations.
In conclusion, short-term tourist rentals in Spain are subject to a triple control system:
- Community level: neighborhood authorization requirement.
- Regional level: tourist licenses and technical requirements.
- State level: National Register, Unique Registry Code, and tax obligations.
The result is a restrictive framework seeking to balance neighborhood protection and property rights with tourist activity. For investors, this means improvisation is no longer possible: specialized legal advice is essential to avoid penalties and safeguard the profitability of the investment.
