San Millán de la Cogolla

Can you build a house on rustic land?

La Rioja requires at least 2 ha for a new house on dry, unirrigated rustic land.

Other cases: 5,000 m² on irrigated rustic land.

Ley 5/2006, art. 52. A town plan can be stricter.

Plan in force: Normas Subsidiarias (an older, simpler plan), from 1996. The region's planning viewer ↗

The SIU does not map land classes here: the town plan is the source.

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 Millán de la Cogolla. That is not proof there is no water: ask local drillers. 10 springs are recorded.

Ground: 60% practically impermeable; 17% low permeability, local groundwater only; 12% porous aquifer, medium productivity; 7.7% karstic or fissured aquifer, high productivity.

Choosing where to drill takes a hydrogeologist.
