    Submit declaration or apply for license at Cartagena City Hall

    Go to official site

    For many commercial and service activities, a declaration of responsibility suffices to open your business before the Cartagena City Hall. For more impactful activities (bars, workshops, industries) you need a full business license. In the Region of Murcia, opening procedures are handled by the local city hall. The INFO offers pre-orientation on requirements and accompanies entrepreneurs through the process.

Frequently asked questions

What is the difference between a business license and a declaration of responsibility?
The declaration of responsibility allows you to open immediately, assuming that all legal requirements are met by the owner. The city hall can verify this later. A business license requires a prior inspection from the city hall and may take months. For most commercial and office activities without special impact, a declaration of responsibility is sufficient.
How much does a business license cost in Cartagena?
The cost of a business license varies according to the Cartagena City Hall and type of activity. For simple activities (offices, small shops) the municipal fee usually ranges from €100 to €300. For classified activities (hotels, workshops) it may exceed €1,000 due to required technical reports.
Can I open a business from home in Spain?
Yes. Many service, consulting or online sales businesses can be operated from your private residence. In that case, the 'premises' is your home and, if no public presence, usually does not require municipal license. However, you must register with the Tax Agency and Social Security.
What happens if I open a business without a license?
Opening without the appropriate license or declaration of responsibility can result in municipal fines ranging from hundreds to thousands of euros, up to sealing off your premises. City halls have activity inspectors who conduct periodic controls.
Do I need to do works to adapt the premises?
If the premises require works, you must apply for a construction permit or prior communication of work with the city hall before starting any work. Minor works (painting, light installations) are usually processed via prior communication. Major works require a technical project and construction permit.
