What rustic land in Mainar 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?
Aragón requires at least 1 ha for a new house on rustic land.
DL 1/2014, art. 34.2. A town plan can be stricter.
Plan in force: Plan General (a full town plan), from 2026. 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?
IGME records 2 wells and boreholes in Mainar. Half of the 2 with a depth found water at 14–20 m. One spring is recorded.
Ground: 38% practically impermeable; 19% low permeability, local groundwater only; 18% porous aquifer, medium productivity; 17% karstic or fissured aquifer, medium productivity; 7.6% porous aquifer, high productivity.
Choosing where to drill takes a hydrogeologist.
