Cartaya

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.

Decreto 550/2022, art. 31. A town plan can be stricter.

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 160 wells and boreholes in Cartaya. Half of the 153 with a depth found water at 8–48 m. One spring is recorded.

Ground: 71% porous aquifer, medium productivity; 17% practically impermeable; 9.5% low permeability, local groundwater only.

Choosing where to drill takes a hydrogeologist.
