Summary

In detail
The planning requirements differ depending on where the business is established.
Therefore, if you wish to install a sign or advertising device on a façade or in the establishment, you should contact the urban planning department of the municipality concerned to find out what you need to do.
Costs
An annual tax is payable.
The amount of this annual tax on signs and advertising is set by the legislation of the municipality concerned. Therefore, you should contact the municipality about this.
