Licenses required for attic renovations in Barcelona

In Barcelona, attic renovations require different licenses depending on the type of work to be carried out. The main permits you may need are:

Prior notice of work

If the renovation of your penthouse does not affect the structure of the building, the façade or the common elements, you only need to submit a prior communication to the Barcelona City Council. This type of work includes:

  • Change of floors, windows and carpentry.

  • Renovation of electrical and plumbing installations.

  • Improvements in thermal and acoustic insulation.

Minor works license

If the renovations involve modifications to the layout of the space, the replacement of partitions or changes to the roof without affecting the structure, you will need to apply for a minor works permit. Some examples are:

  • Demolition or construction of internal partitions.

  • Installation of false ceilings or coverings.

Major works license

If the attic renovation includes structural changes, extensions or modifications to the façade, it is necessary to obtain a major works permit. This permit is essential for:

  • Extensions of the living area.

  • Structural reinforcements in floors or roofs.

  • Construction of new terraces or balconies.
