The municipality has the authority to determine that you may not place certain objects or objects near a high voltage line. This includes a distance within which no object may be placed. Would you like to place an object anyway? If so, you will need a permit or a notification.
Permit
The cost of the permit can be found in the fees ordinance. You also pay precario tax, see precario tax ordinance.
Notification
You pay precario tax, see precario tax regulation.
