Carrying out a full renovation in Barcelona without the proper permits can lead to heavy fines or the immediate suspension of the works. Building regulations in our city are strict but necessary to guarantee the safety of the buildings.
According to current **2026** regulations, most procedures are managed through the **Barcelona City Council E-Office (Sede Electrónica)**. Depending on the scope of your project, the procedure will be one of these three:
1. Assabentat d’obres (Immediate Notification)
This is the simplest procedure for **minor works** that do not modify the structure, the layout, or the facade (for example: changing the floor, painting, or renovating the kitchen/bathroom while keeping the original location of the elements).
Advantage: Obtained instantly online and free of charge.
This permit is mandatory when the project involves **changing the flat’s layout** (removing walls), affecting common elements, or a complete renewal of utility installations.
Requirement: Requires payment of municipal taxes and the involvement of a **licensed technician** (Architect or Technical Architect) to sign the technical documentation.
3. Major Works License (Llicència d’Obres Majors)
Reserved for major structural changes (such as opening gaps in load-bearing walls), surface extensions, or interventions in buildings with **heritage protection**, very common in districts like **Eixample, Gràcia, and Ciutat Vella**.

>How do we manage this at A. Barcelona Reformas S.L.? We understand that bureaucracy can be stressful. Therefore, our technical team assumes full administrative responsibility for your renovation:
In-house Technical Project: We have licensed architects to draft and sign all necessary blueprints.
End-to-end Processing: We manage all documentation via the Barcelona City Council Procedures Portal.
Tax Management: We handle the calculation and payment of the ICIO tax.
Public Space & Debris: We request permits for containers or waste bags, preventing fines from the City Police (Guardia Urbana).
ITE Advisory: If your building is old and has a pending Technical Building Inspection (ITE), we ensure the renovation meets all specific requirements.
⚠️ Do you live in a protected building in Barcelona?
Not all renovations in Barcelona follow the same process. If your property is located in a district with high historical value, the Barcelona City Council applies much stricter urban regulations:
• L’Eixample: The district with the most iconic fincas regias and Catalan vaulted ceilings (volta catalana). Any layout modification or restoration of original features usually requires a detailed technical report.
• Ciutat Vella (Gothic, Raval, Born): Due to the buildings’ age and narrow streets, debris logistics are complex, and structural control is strictly enforced to ensure safety.
• Gràcia: Many properties are listed as heritage sites. Even simple window replacements may require a specific license if they affect the building’s protected facade.
Expert Tip: Before applying for your Assabentat, we check your property’s Cadastral Reference to confirm if the building has any level of protection (Level A, B, or C). This prevents unexpected fines and administrative delays.
📋 Required Documentation: What should you have ready?
To allow us to start the procedures with the Barcelona City Council today, we will need you to provide the following documents:
Owner’s ID/NIE: Copy of both sides.
Property Deeds or “Nota Simple”: To prove ownership of the property.
Cadastral Reference: You can find it on your latest IBI (property tax) receipt.
Latest IBI Receipt: Required to verify census data.
Signed Authorization: A simple document authorizing A. Barcelona Reformas s.l.to act on your behalf at the Electronic Office.
Current Floor Plan (if available): Helps our technical team speed up the quote and project.
