Converting a building into a hotel: which licensing route applies?

A change of use is a separate category of works

Converting a building into a hotel constitutes a change of use (canvi d'ús). In Barcelona, a change on this scale requires a full technical design and therefore follows the licencia de obras mayores route, the most demanding regime described in our guide to works licences. A simple notification—comunicat immediat, comunicat diferit or assabentat—is insufficient: the scale of the changes rules out a lighter procedure. This applies even where the building’s façade changes little visually. The change of use itself, rather than the amount of visible construction, determines the applicable regime.

A works licence is not the first question

The most common mistake is to find a building, become attached to its location and potential, and only then discover that a hotel cannot open there. A works permit governs HOW the building can be converted. It does not answer WHETHER a hotel can be located at that address at all. The PEUAT zone determines that issue. If the property is in Zone 1, no new hotel licence will be issued regardless of the quality of the technical design.

The correct three-step sequence

For DNPI’s hotel strategy, a realistic sequence is:

1. Confirm that the PEUAT zone allows hotel use at the address.
2. Check whether the building’s protected status prevents the structural changes required. This is especially relevant in the historic centre; see our article on heritage protection.
3. Only then assess the major-works licence project: the scope of the technical design, approval timetable and cost of works.

Changing this order does not save time: it wastes it. An investor who commissions an architectural design before discovering a PEUAT prohibition or heritage restrictions loses both design fees and time spent searching for an alternative property.

Two successive filters, not alternatives

PEUAT and protected status are not alternatives to choose between. They are successive conditions, both of which must be satisfied. Passing the zoning check says nothing about the building’s heritage status, and vice versa. Only after both filters have been passed does it make sense to move on to the substance of the works under a hotel strategy: room layouts, building services, fire regulations for hotel use, and a realistic major-works licence approval timetable. Checking in reverse order—designing first, then assessing zoning and protection—does not guard against risk. It merely delays discovery until a more expensive stage of the project.

The implication for investors

A building that looks ideal for a hotel may be unviable for reasons unrelated to its physical characteristics, such as zoning or area protection. Checking these two issues before any other work on the property is not a formality. It prevents design money being spent on a project that cannot obtain a licence.
