San Martín de Oscos

Can you build a house on rustic land?

Asturias allows a new house on rustic land only where the town plan provides for it.

DL 1/2004, art. 124. A town plan can be stricter.

Plan in force: Normas Subsidiarias (an older, simpler plan), from 2002. The region's planning viewer ↗

The national urban information system (SIU) maps the land class for 99% of the municipality.

Only the town hall can confirm it, in writing: ask for a certificado urbanístico.

Is there water?

No well or borehole is recorded in San Martín de Oscos. That is not proof there is no water: ask local drillers. 12 springs are recorded.

Ground: 97% practically impermeable.

Choosing where to drill takes a hydrogeologist.
