Short

The room in Catalonia is a rental dwelling: Llei 11/025 (effective from 01.01.2026) explicitly states that the division of the apartment into rooms does not change the rules of the rental of the dwelling. [1].
In the mercat residual zone, which includes Barcelona, the rent payments under simultaneous contracts for one dwelling cannot exceed the maximum for the entire apartment [1][4].
If you rent a room from the tenant, he needs the owner's written consent for the sublease, the sublease price is not higher than the principal lease price, and your right ends with his contract. [2].
Under LAU, the tenant of the apartment is entitled to move within six months, with 30 days' notice, and the deposit (fianza en metálico) is legally equal to one month's lease [2].
If the contract does not state that it is temporary, it is considered that he is a permanent resident. [1].

How does the room contract differ from the apartment contract?

Under Llei 11/025, which amended the Law of Catalonia on the Right to Housing Llei 18/2007, the rental of a room is a contract whereby the owner grants the tenant exclusive right to the room and the right to use common premises for payment. The Law adds two conditions: the area per person and the limit of the number of tenants must not violate the rules of cédula de habeaslid (deputy certificates) and the division of the accommodation into rooms does not cancel. Rent regulations [1].

The apartment contract is entirely regulated by LAU (Ley 29/1994 on urban rentals), and the Catalan legislature has a room contract that is considered a rental of housing, but as this regime is combined with the federal LAU regime by duration and extension, we have not found in the official explanations.

What changes if the room isn't rented out by the owner?

Article 8 LAU allows only part of the dwelling to be sub-rented and only with the prior written consent of the lessor; the sub-rent price may not exceed the price of the main lease and the sub-rentor ’s right shall cease when the right of the main lessee ceases to exist [2]Substitution without the owner ’s consent is also included in the list of reasons why the owner may terminate the underlying contract [2].

Before paying, ask for written consent or contract with the owner.
