What rustic land in Trefacio allows and holds, for the municipality as a whole. For a particular plot, open it in the map: the report answers for that exact point.
Can you build a house on rustic land?
Castilla y León allows a new house on rustic land only when a farm needs it. Otherwise it has to go in a village, or restore a building.
Ley 5/1999, art. 23.1.e. A town plan can be stricter.
No town plan: the region's general rules apply. 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 Trefacio. That is not proof there is no water: ask local drillers.
Ground: 92% practically impermeable; 6.3% porous aquifer, high productivity.
Choosing where to drill takes a hydrogeologist.
