Opening your own business is an exciting step, but it also brings the need to navigate various administrative and technical procedures. The most important of these for any physical establishment is, without a doubt, the activity or opening license. In this article, we explain clearly and in detail how this procedure works at the Barcelona City Council in 2026 and how to streamline it so you can open your premises as soon as possible.
What is the activity license and why is it mandatory?
An activity license is a mandatory municipal authorization certifying that a commercial premises, office, or industrial warehouse meets the technical and regulatory conditions to carry out a commercial or industrial activity without generating risks to public health, safety, or the environment. In Catalonia, this is mainly regulated by Law 16/2015 on administrative simplification and the corresponding municipal ordinances of the Barcelona City Council.
Classification of activities in Barcelona
The first essential step is to know the classification of the activity you want to set up. In Barcelona, the procedures are divided into different levels of intervention based on the dimensions and potential impact of the business on the community:
1. Responsible Declaration or Innocuous Communication (Annex III)
Corresponds to low-risk or low-impact activities (non-food retail stores, service offices, travel agencies, etc.). The process is immediate: once the documentation is prepared and the municipal fees are paid, the business can open on the same day.
2. Environmental Communication with Technical Certificate (Annex II)
Applies to medium-risk activities (restaurants, medical clinics, large academies, mechanical workshops, or hair salons). In this case, it is mandatory to have a technical project approved by a licensed engineer certifying that the premises comply with fire protection, universal accessibility, and noise regulations.
3. Qualified Activity License (Annex I)
Reserved for high-impact activities or large-scale industrial setups (hotels, nightclubs, massive sports centers, or heavy industries). This procedure requires prior municipal approval before starting work or opening.
Important: Opening a business in Barcelona without the proper license or carrying out an activity other than the permitted one can lead to severe fines from €3,001 to €600,000 and the immediate closure of the premises by the Guardia Urbana.
Step-by-Step to Process your Opening License
If you want to ensure the technical viability of your project and open your business without technical surprises, we recommend following these steps:
- Urban planning feasibility study: Before signing the rental or purchase contract for the commercial space, consult with a licensed engineer to check the zone ordinances of the district and if there is a uses plan restricting the opening of certain types of businesses (such as bars or restaurants).
- Technical inspection visit: A licensed engineer will visit the premises to take measurements, verify headroom, ventilation, fire escape routes, and bathroom accessibility.
- Technical Project Drafting: The engineer prepares the technical memory, detailed layout plans of the premises in AutoCAD, fire load calculations, and the acoustic isolation plan.
- Obtaining the college visa: The project is sent to the corresponding professional association to guarantee its formal legality.
- Fee payment and City Council submission: Municipal fees associated with the opening application are paid, and the file is submitted through the Barcelona City Council procedures portal.
- Inspection by the Environmental Control Entity (EAC): For Annex II activities, an authorized collaborating entity will inspect the premises before the final certificate of conformity is issued.
How much does it cost to get an activity license in Barcelona?
The final cost depends on three main factors:
- Professional engineering fees: Vary depending on the surface area of the premises and the complexity of the activity (from €800 for innocuous offices to €2,500 or more for restaurants with a kitchen).
- Municipal City Council fees: Depend on the square meters of the premises and the type of procedure (usually between €300 and €1,200).
- Physical adaptation of the premises: If the premises do not comply with accessibility, structural fire resistance, or soundproofing, renovations will be necessary.
