Do you want to know if you have to submit a notification or if you need an all-in-one permit for physical aspects (omgevingsvergunning)? You can do an online permit check on the online service counter (omgevingsloket in Dutch).
The cost depends on which all-in-one permit for physical aspects you apply for.
