Frequently asked questions

What is the difference between a business opening license and a responsible declaration?
A responsible declaration allows you to open immediately, assuming compliance with all legal requirements. The city hall may verify this later. A full business license requires prior inspection by the city hall and can take months. For most commercial activities without special impact, a responsible declaration suffices.
How much does it cost for a business opening license in Avilés?
The cost of the business opening license varies according to Avilés City Hall and type of activity. For harmless activities (offices, small shops), municipal fees usually range from 100€ to 300€. For classified activities (bars, 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 carried out from your personal residence. In that case, the 'business premises' are your home and you typically do not need a municipal license, unless there is public access. But you must register for tax and social security.
What happens if I open without a business opening license?
Opening without the appropriate license or responsible declaration can lead to municipal fines ranging from hundreds to thousands of euros, including sealing your premises. City halls have activity inspectors who conduct periodic checks.
Do I need renovations for adapting the premises?
If the premises require renovation, you must apply for a building work license or prior notification of works at the city hall before starting any work. Minor works (painting, light installations) can usually be done through a prior notification. Major works require a technical project and a building work license.
