    Apply for declaration of responsibility or license with the Barcelona City Hall

    For many commercial and service activities, a declaration of responsibility for opening is sufficient. For more impactful activities (bars, workshops, industries), you need a full business license. The Generalitat's Canal Empresa portal allows online submission of the communication of opening for most activities. Municipalities in Catalonia have their own licensing competencies, so the process may vary according to the municipality.

Frequently asked questions

What is the difference between a business license and declaration of responsibility?
The declaration of responsibility allows you to open immediately, assuming that all legal requirements are met. The city hall can verify this later. A full business license requires a prior inspection by the city hall and can take months. For most commercial businesses without special impact (offices, small shops) a declaration of responsibility is sufficient.
How much does it cost to get a business license in Barcelona?
The cost of the business license varies according to the Barcelona City Hall and the type of activity. For harmless activities (offices, small businesses), the municipal fee usually ranges from €100 to €300. For classified activities (cafes, workshops) it can exceed €1,000 due to required technical reports.
Can I open a business from home in Spain?
Yes. Many service-related businesses, consulting or online sales may be conducted from your private residence. In that case, the 'location' is your home and you typically do not need municipal licensing if there is no public presence. However, you must still register for tax and social security.
What happens if I open a business without a license?
Opening a business without the appropriate license or declaration of responsibility can result in city hall fines ranging from hundreds to thousands of euros, even up to sealing the premises. City halls have activity inspectors who conduct periodic checks.
Do I need to make renovations to adapt the location?
If the location requires renovations, you must apply for a building permit or prior notification of work in the city hall before starting any works. Minor works (painting, light installations) are usually processed through prior notification. Major works require a technical project and building permit.
