Esterillos: the Maritime Zone, measured

Only 13.6% of Esterillos's maritime strip is covered by registered parcels — much of this coast remains unregistered public domain, which does not make it buyable: it makes it state land with no registered rights at all. Roughly 27% of the strip overlaps protected land, where restrictions are far stricter than the normal concession rules.

• Identify the exact parcel on the cadastre and confirm whether it sits inside the 200m strip, touches the 50m public zone, or lies safely beyond.
• Concession or title? In the restricted band assume concession until the registry proves otherwise; verify the seller is the registered holder and the term, use and canon are current.
• Check the plan regulador with the municipality before believing any "you can build X" claim.
• Overlay the environment — protected areas, river setbacks and flood exposure change what is possible parcel by parcel.
• Foreign buyer? Remember the art. 47 rules (5-year residency, max 50% foreign capital in a concession-holding company).
