Official sources:25 of 28 responding· checked 16 min ago
Oviedo, Gijón y el resto de Asturias: no response right now. If you search there and get no verdict, it is not that the address isn't covered: the official source is down. It rarely lasts long.
LocalCheck does not store planning data: it asks the councils' and regions' services on every search. This shows whether they answer.
