San Martín de la Vega

Can you build a house on rustic land?

The Madrid region allows no new houses on rustic land. Restoring an existing or listed building is the way.

Ley 9/2001, art. 29. A town plan can be stricter.

Plan in force: Normas Subsidiarias (an older, simpler plan), from 1997. 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?

IGME records 26 wells and boreholes in San Martín de la Vega. Half of the 26 with a depth found water at 5–16 m. One spring is recorded.

Ground: 48% low permeability, local groundwater only; 28% porous aquifer, medium productivity; 17% porous aquifer, high productivity; 6.7% practically impermeable.

Choosing where to drill takes a hydrogeologist.
