Llar compartida
shared home — renting rooms in the home you live in to guests
Definition
A llar compartida is Catalonia's legal category for renting rooms in the home you live in to guests for stays of 31 days or fewer. The home must be your main residence, you must live there during the stay, and the guests share it with you.
Why it matters
The conditions are specific. The person running it must be the owner or someone the owner has expressly authorised — so a tenant needs the landlord's permission. Capacity is capped at four guests in total, each room must be private with its own door, and the Catalan tourism register number has to appear in every listing.
Catalan law lets a municipality's planning rules limit or prohibit the activity, and Barcelona does: its tourist-accommodation plan (PEUAT) prohibits renting rooms to tourists for stays of under a month anywhere in the city. Renting a room for longer than that, as someone's home, is a different arrangement and remains possible.
So the first question is never the price — it is where the home is. The same spare room can be a legal llar compartida in one Catalan municipality and a sanctionable tourist let a few kilometres away.
Example
A tenant with a spare room outside Barcelona city wants to host for a week at a time. Before any listing: confirm it is their main residence, get the landlord's written authorisation, check the municipality allows shared homes, and register — in that order.
