San Roque de Riomiera

Can you build a house on rustic land?

Cantabria allows a new house on rustic land only within 200 m of a village, on at least 1,500 m².

Ley 5/2022, art. 51. A town plan can be stricter.

Plan in force: Normas Subsidiarias (an older, simpler plan), from 1990. 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 Roque de Riomiera. That is not proof there is no water: ask local drillers. 9 springs are recorded.

Ground: 66% karstic or fissured aquifer, high productivity; 34% low permeability, local groundwater only.

Choosing where to drill takes a hydrogeologist.
