Baztan

Can you build a house on rustic land?

Navarre allows a new house on rustic land only where the town plan provides for it, on at least 1 ha.

DFL 1/2017, art. 115. A town plan can be stricter.

Plan in force: Plan General (a full town plan), from 2003. The region's planning viewer ↗

The national urban information system (SIU) maps the land class for 100% 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 Baztan. That is not proof there is no water: ask local drillers.

Ground: 51% low permeability, local groundwater only; 40% practically impermeable.

Choosing where to drill takes a hydrogeologist.
