Step by step

  • 1

    Check urban compatibility of the premises

    Register with Hacienda and Social Security

    Go to official site

    If you are not yet registered as a freelancer, do so first. Model 037 at AEAT and registration in RETA via Importass. Without this step, you cannot proceed with the opening.

    Apply for the responsible declaration or license at the Castellón de la Plana City Hall

    Go to official site

    For many commercial and service activities, a responsible declaration of opening suffices before the Castellón de la Plana city hall. For more impactful activities (bars, workshops, industries), you need a full activity license. The Generalitat Valenciana provides the Emprendedor Point of Attention (PAE) network for business orientation. Opening permit procedures are handled at the corresponding city hall.

Frequently asked questions

What is the difference between an opening license and a responsible declaration?
The responsible declaration allows you to open immediately, assuming that all legal requirements are met. The city hall can verify this at a later date. The full activity license requires prior inspection by the city hall and may take months. For most commercial activities with no special impact, a responsible declaration suffices.
How much does an opening license cost in Castellón de la Plana?
The cost of the opening license varies according to the Castellón de la Plana city hall and type of activity. For harmless activities (offices, small businesses), municipal fees typically range 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, consulting or online sales activities can be conducted from your private residence. In this case, the 'premises' are your home and you don’t usually need a municipal license if there is no public presence. However, you must register with Hacienda and Social Security.
What happens if I open without an opening license?
Opening without the required license or responsible declaration can result in municipal fines ranging from hundreds to thousands of euros, up to sealing off the premises. City halls have activity inspectors who conduct periodic checks.
Do I need renovations to adapt my premises?
If your premises require renovations, you must apply for a construction license or notification of works at the city hall before starting work. Minor works (painting, light installations) are usually processed through a notification system. Major works require a technical project and a construction license.
