Hall of residence or university residence in Spain: what separates them legally, and what the LOSU changed (2026)
They get used as synonyms and they are not. Since March 2023 the difference is written into an organic act, with concrete consequences for who may run each one, what tax benefits it has, and which coexistence obligations reach it.
What the law actually says
The figure of the *colegio mayor* — a Spanish institution with no exact equivalent in English, which is why this guide keeps the Spanish name — is defined today by Organic Act 2/2023 on the University System (LOSU), in its seventh additional provision. It is worth reading in full, because it is four short paragraphs and each one has consequences.
«Colegios mayores are centres which, integrated into the University, provide residence for university students and promote cultural and scientific outreach activities that strengthen the all-round education of their residents. These colleges constitute university institutions.»
The last sentence is the one that carries the weight: a university institution. A *colegio mayor* is not an accommodation provider with activities — it is part of the university. A university residence provides an accommodation service, and that is the whole difference everything else hangs from.
Who may run each one
This is the paragraph that surprises most people, and the one that closes the door on a confusion that is frequent among operators.
«University colegios mayores may only be managed and promoted by non-profit entities.»
Ojo con esto
Careful about inferring the legal figure from the sign over the door: they don't match. There are buildings marketed today as «Colegio Mayor» by operators that are commercial companies — historic names that survived a change of management. That the door says «Colegio Mayor» does not mean that centre is a university *colegio mayor* in the sense of the LOSU.
What settles the figure is not the name: it is recognition — granted by ministerial order at the request of the vice-chancellor's office, under Decree 2780/1973, which is still in force — and integration into or affiliation with a university. And that matters, because which route the coexistence obligations reach the centre by hangs from it. To know, you have to look at the file, not the façade.
How to tell whether a centre really is a colegio mayor
The LOSU defines the figure, but does not create the procedure: that remains in Decree 2780/1973, which regulates University Colegios Mayores and which is not repealed. Its Article 4(1) says colegios mayores may be created by the university itself or promoted by other public or private entities, and Articles 5 and 6 set the path: the application is submitted to the vice-chancellor's office, which raises it to the ministry, and recognition arrives by ministerial order. Article 26 also provides for the loss of that status by the same route.
From that come the three things to check, and none of them is the name:
- Recognition by ministerial order as a university *colegio mayor*.
- Integration into or affiliation with a specific university, and on what terms.
- The nature of the entity that manages and promotes it, which since the LOSU must be non-profit.
Affiliation and tax benefits
Paragraph 3 refers to each university's Statutes the rules on the creation, closure and operation of directly founded colegios mayores, and the affiliation procedure for affiliated ones. And it adds a practical consequence no residence has: affiliated colegios mayores «shall enjoy the tax benefits or exemptions of the university they are integrated into».
Paragraph 4 introduces a rule that is still live and has a calendar of its own: private colegios mayores with a single-sex or segregated regime cannot affiliate with a public university. Agreements in force when the act came into effect may be maintained until they expire, but not renewed.
It is a matter of calendar more than of debate: it affects a small group of centres, and the compliance route most of those affected have taken has been conversion to a mixed regime, mostly begun from the 2023-24 academic year. For a centre affiliated with a public university, the practical thing is to know when its agreement expires, because that date is what governs.
The comparison, in a table
| Colegio mayor | University residence | |
|---|---|---|
| Nature | A university institution, integrated into the university (LOSU, 7th additional provision, 1) | An accommodation service. Not a university institution |
| Who may run it | Only non-profit entities (7th add. prov., 2) | Any owner, including commercial companies |
| Educational remit | Yes: cultural and scientific activities, all-round education | Not required by law; many offer it by their own choice |
| Tax treatment | Affiliated ones enjoy their university's benefits (7th add. prov., 3) | Whatever general regime its activity attracts |
| Act 3/2022 on coexistence | Always reaches it, through its integration into the university | Only if it is affiliated with a university |
| GDPR | The same for both | The same for both |

What changes in coexistence, and what doesn't
Act 3/2022 on university coexistence names neither of the two figures: it binds the university. That is why the route by which it reaches a centre is what decides whether it applies.
- Colegio mayor: by definition it is integrated into the university, so that university's Coexistence Rules bind it and its house rules have to fit with them.
- Affiliated residence: same route, through the affiliation.
- Private residence with no link: Act 3/2022 does not reach it. It is still reached by the obligations that don't depend on the university — data protection, workplace prevention and, if the entity has fifty or more employees, Act 2/2023.
The rule that applies to both
Royal Decree 1791/2010, the Statute of the University Student, requires that the rules on access to and management of accommodation services guarantee equal rights through a public, objective and transparent procedure, known sufficiently in advance and accessible to people with disabilities. That draws no distinction between figures.
Why this distinction isn't just terminology
It has three practical effects that come up in any serious conversation in the sector: it decides who may operate a centre, it decides what tax regime applies to it, and it decides by which route the coexistence obligations reach it. Confusing the two when drafting house rules or negotiating an affiliation is an expensive mistake, which is why it pays to have the text of the provision in front of you rather than custom.
Frequently asked questions
Are a colegio mayor and a university residence the same thing?
No, and since 2023 the difference is written down. The seventh additional provision of the LOSU defines the colegio mayor as a centre integrated into the university that provides residence and promotes cultural and scientific activities, and adds that these colleges constitute university institutions. A university residence provides accommodation and services, but it is not a university institution and has no such educational remit.
Can a company run a colegio mayor?
A university colegio mayor, no: paragraph 2 of the seventh additional provision of the LOSU reserves its management and promotion to non-profit entities. But it is worth not drawing a broader conclusion than fits. There are buildings marketed as «Colegio Mayor» by commercial operators, almost always historic names kept on through a change of manager, and the sign does not evidence the legal figure. What evidences it is recognition by ministerial order and integration into or affiliation with a university.
What about colegios mayores that are not mixed?
Paragraph 4 of the same provision prevents private colegios mayores with a single-sex or segregated regime from affiliating with a public university. Agreements already in force when the act came into effect may be maintained until they expire, but not renewed.
Do both have the same coexistence obligations?
Not exactly, and the route differs. Act 3/2022 on university coexistence binds universities, and reaches a centre through its integration or affiliation. A colegio mayor, which by definition is integrated, always has it. A private residence with no university link does not — although it is still reached by the general obligations that don't depend on the university.
And the data protection obligations?
There is no difference there. The GDPR and Spain's LOPDGDD apply equally to a colegio mayor, a private university residence and a coliving space: whoever decides the purposes for which residents' data is processed is the controller, whatever its legal form and whether or not it is run for profit.
Do colegios mayores have tax benefits?
Paragraph 3 of the seventh additional provision says that affiliated colegios mayores shall enjoy the tax benefits or exemptions of the university they are integrated into. It is one of the most tangible practical consequences of the figure, and a residence does not have it.
