On the question of consequence

Of the sanctioning regime applicable to infractions of the registry obligation — its statutory source, its two brackets, the role of recurrence and intent, and the collateral effects that extend beyond the fine.

The regulation that is the subject of this series — Real Decreto 933/2021 — does not itself contain a sanctioning regime. The reason is one of constitutional architecture rather than oversight: under Spanish public–law doctrine, the imposition of penalties of a punitive character requires a basis in legislation of formal rank, and a real decreto of executive nature is not such a basis. The sanctioning regime applicable to infractions of the registry obligation is found, accordingly, in the parent legislation that habilitates the decree — namely, the Ley Orgánica 4/2015, de 30 de marzo, de Protección de la Seguridad Ciudadana, and specifically in its articles 36 to 38.¹ The regulation operates, in this respect, as a specification of the conduct that constitutes infraction; the law operates as the source of the punishment.

Two brackets are drawn by the law. The first, that of the infracciones leves — mild infractions — attracts fines of between one hundred and six hundred euros. Into this bracket fall the most common kinds of breach: communication of guest data outside the twenty–four–hour window; communication that is incomplete or partial in respect of one or more obligatory fields; errors in the transmitted data, whether of typographical character or of more substantive form; and the submission of data that, while not deliberately false, is materially inaccurate. The qualification depends, in the practice of the inspecting authority, less on the formal label than on the operative effect: a communication late by six hours and a communication late by six days will both fall within the leve bracket in the first instance, but only the first will, in the ordinary case, attract the lower end of the scale.²

The second bracket, that of the infracciones graves — serious infractions — attracts fines of between six hundred and one euros and thirty thousand euros. The conduct that falls within this bracket is qualitatively distinct, not merely quantitatively so. It includes, in the first place, the failure of the host to enrol on SES.Hospedajes or its regional equivalent as a prestador: this single omission — which precedes any individual communication — is itself sufficient to engage the grave bracket. It includes, in the second place, the total omission of the communication of guest data, where the host has captured and retained the data but has not transmitted it. And it includes, in the third place, the case of recurrence: the persistence or repetition of leve infractions converts the conduct, by operation of article 37 of the parent law, into a grave one.³

Between the two brackets there operates a doctrine of graduation articulated in article 38 of the parent law. The competent authority, in determining the precise quantum within the relevant bracket, is to consider the entity of the breach, the harm caused, the degree of intent or negligence, the economic capacity of the offender, the antecedents of the offender, and the existence of any rectification or remediation. The doctrine is, in practical effect, what mediates between a fine of one hundred euros and a fine of six hundred, or between a fine of six hundred and one and a fine of thirty thousand. An offender who, upon notice of inspection, presents complete documentation of an ultimately rectified breach will fare materially better than one who does not.⁴

The competent authority is, in the autonomous communities subject to the central regime, the Ministerio del Interior: more specifically, the Secretaría de Estado de Seguridad at the level of central administration, and the territorial Subdelegaciones del Gobierno at the level of the province. In Catalonia, the sanctioning competence corresponding to the Catalan registre is exercised by the autonomous administration through the channels of the Generalitat; in the Basque Country, by the corresponding Basque authority. The procedural framework is in each case that of the Spanish administrative sanctioning procedure — preliminary instruction, formal allegation, hearing of the interested party, evidentiary phase, resolution, and access to judicial review before the contentious–administrative jurisdiction.

Beyond the cash fine, the host who has been the subject of a firm sanctioning resolution faces a set of collateral consequences that, in practice, are often more onerous than the fine itself. The inscribed status of the establishment in the tourism registry of the relevant autonomous community may be reviewed, with the result that the host’s licence to operate may be suspended or, in extreme cases, withdrawn. The platforms of intermediation, which since 2025 verify the host’s enrolment on SES.Hospedajes with increased diligence, have begun to suspend listings whose underlying host cannot demonstrate compliance. The reputational effect of an open sanctioning record, while less easily quantified, is not negligible — particularly for hosts who operate at scale and who depend upon trust signals from intermediary platforms and from past guests.

It bears emphasis, finally, that the sanctioning proceedings now under way are not hypothetical. The regime became fully enforceable on 2 December 2024; the inspecting and sanctioning activity of the Ministerio del Interior, after a period of administrative calibration, began in earnest in the course of 2025 and has continued with increasing density into 2026. The intuition that a small operator, or a foreign owner, will be of insufficient prominence to attract attention, while perhaps psychologically comforting, is not borne out by the pattern of proceedings already reported. The risk is real, the consequence is statutory, and the only proportionate response is compliance.
