For property owners in Mijas, short-term rentals remain an attractive opportunity, but the regulatory environment has become considerably more complex. In 2026, hosts need to consider Andalusian tourism rules, Spanish property legislation, local planning requirements and the rules of their Community of Owners before operating a holiday rental.
One important change since the original 2025 guidance is that Spain's national short-term rental registration framework has been subject to several Supreme Court rulings in 2026. The Tribunal Supremo annulled key provisions of the national registration system, including provisions relating to the Registro Único de Arrendamientos, after finding that aspects of the system interfered with autonomous-community competences.
For Mijas owners, this means the Andalusian VUT/VFT framework remains particularly important, while national requirements should be checked against the latest legal position before relying on older 2025 guidance.
Short-term rental compliance in Mijas operates across several levels:
Properties offered as tourist accommodation in Andalusia generally fall under the Viviendas de Uso Turístico (VUT) framework.
Under Decree 31/2024, properties rented for periods of up to two consecutive months to the same tenant fall within the tourist-housing framework, while properties rented for more than two continuous months to the same tenant are excluded.
Owners should ensure that their property:
Apartment owners also need to consider their Comunidad de Propietarios.
Changes to Spain's Horizontal Property Law give communities greater powers over tourist rental activity. Owners considering a new tourist rental should therefore check the property's statutes, title documentation and community decisions before proceeding.
For a property in a shared building, this should be treated as an essential part of due diligence rather than something to investigate after purchasing.
Mijas may apply local planning and zoning controls to tourist accommodation. Local planning restrictions can vary depending on the property and location, so owners should verify that the intended tourist use is compatible with the applicable municipal planning framework.
The municipality continues to update its regulatory and urban-planning framework, making it important to check current requirements rather than relying on information from previous years.
The national Registro Único de Arrendamientos / Ventanilla Única Digital de Arrendamientos was introduced through Royal Decree 1312/2024, with the framework originally taking effect in 2025.
However, 2026 brought significant legal changes. The Supreme Court has annulled important provisions of the national framework, with the BOE reflecting amendments following the relevant judgments.
The practical takeaway for Mijas owners is:
Do not assume that information published in 2025 about the national registration system remains unchanged in 2026.
Owners should confirm the current position with the relevant authority or qualified Spanish legal adviser before applying, renewing or relying on a national registration number.
This is particularly important for properties advertised through online platforms.
A Mijas property used as tourist accommodation must meet the applicable Andalusian requirements.
Depending on the property and its circumstances, this can include:
Owners should verify the precise requirements applicable to their property rather than assuming that an older VUT registration automatically means the property meets every current standard.
Legal compliance doesn't stop once a property has been registered.
Tourist accommodation operators must also comply with Spain's requirements concerning guest identification and reporting.
A professional management company can help coordinate:
This can be particularly useful for overseas owners who are not based in Mijas.
Rental income generated from a Spanish property is subject to Spanish tax obligations.
The precise treatment depends on factors including:
Non-resident owners should obtain professional tax advice regarding Modelo 210 and the treatment of rental income.
Tax rules can also change, so figures published in older guides should not be treated as current tax advice.
The biggest lesson for owners is that compliance needs to be checked continuously.
The regulatory environment has moved beyond simply obtaining a tourist licence and listing a property online.
Before launching or continuing a short-term rental, owners should consider:
| Requirement | What owners should check |
|---|---|
| VUT registration | Confirm the property is correctly registered with the Andalusian Tourism Registry |
| Planning compliance | Check that tourist use is permitted for the specific property |
| Community rules | Review statutes, title documents and community decisions |
| Property standards | Confirm heating, air conditioning, equipment and safety requirements |
| Guest registration | Follow applicable identification and reporting requirements |
| Insurance | Maintain appropriate cover for tourist accommodation |
| Tax | Declare rental income correctly and obtain professional advice where required |
| Online listings | Ensure required registration and property information is displayed |
| National rules | Check the latest legal position following the 2026 court rulings |
| Ongoing compliance | Monitor changes to Andalusian, Spanish and Mijas regulations |
Compliance should come before revenue optimisation. Once a property is legally ready to operate, professional Airbnb management can help improve its performance.
A full-service short-let management approach can include:
For Mijas owners, local knowledge is particularly valuable because demand can differ considerably between areas such as La Cala de Mijas, Riviera del Sol, Calahonda and Mijas Costa.
A professional manager can adjust pricing and availability around seasonality, local demand and booking patterns while ensuring operational procedures remain consistent.
Pass the Keys provides a full-service short-let management approach for property owners who want professional support rather than managing every aspect of hosting themselves.
Support can include:
Because regulations can change, owners should obtain specialist legal or tax advice for matters requiring formal interpretation.
If your property falls within Andalusia's tourist accommodation framework, you generally need the appropriate VUT registration with the Registro de Turismo de Andalucía before operating as a tourist rental. The property's planning and community position should also be checked.
Potentially, yes. Spanish property law gives Communities of Owners significant powers concerning tourist rental activity. Before starting a new short-term rental, check the community's current statutes, agreements and applicable voting requirements.
Yes. The national framework introduced through Royal Decree 1312/2024 has been affected by Supreme Court rulings in 2026, which annulled important provisions.
For this reason, owners should not rely solely on 2025 articles about the national registration system and should verify the current requirements.
Yes. In addition to regional tourism requirements, owners need to establish whether tourist use is compatible with the applicable planning rules for their particular property and location in Mijas.
Tourist accommodation operators in Spain are subject to guest identification and reporting requirements. A professional management company can help ensure the required information is collected and submitted correctly.
Generally, rental income from Spanish property can create Spanish tax obligations for non-resident owners. The exact treatment depends on the owner's circumstances, residency and the type of rental activity, so professional Spanish tax advice is recommended.
Potentially. Andalusia's VUT rules exclude properties rented for more than two consecutive months to the same tenant, although other Spanish rental legislation and contractual requirements may apply.
Before purchasing, check the property's VUT eligibility, planning status, Community of Owners' position, existing licences or registrations, technical requirements and tax implications. This due diligence can help prevent buying a property that cannot legally be operated as the intended short-term rental.
Pass the Keys can provide operational support and help identify the requirements that need to be addressed before management begins. Where formal legal or tax advice is required, owners should use an appropriately qualified Spanish professional.
