Can you build a house on rustic land?

Andalucía requires at least 2.5 ha for a new house on rustic land.

Other cases: 5 ha on forest land.

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?

IGME records 7 wells and boreholes in Olvera. Half of the 6 with a depth found water at 7–122 m. 15 springs are recorded.

Ground: 86% low permeability, local groundwater only; 8.7% karstic or fissured aquifer, high productivity.

Choosing where to drill takes a hydrogeologist.
