Do You Need a Permit for a Backyard Pond or Water Feature? in Spanje
Sometimes. Small decorative ponds and self-contained water features are often exempt from permits in most jurisdictions. However, larger ponds with plumbing connections, electrical pumps, or those located near property lines, easements, or natural waterways typically require a building, electrical, or grading permit. Depth restrictions — often 18–24 inches — also determine whether a permit is needed.

Country-specific detail
In Spain, building an estanque (pond) or fuente decorativa (decorative fountain) in a private jardín typically requires at least a declaración responsable or licencia de obra menor from the Ayuntamiento, depending on the municipality and the scale of excavation. In comunidades autónomas with water scarcity regulations (especially Andalucía, Murcia, and parts of Valencia), additional restrictions may apply regarding water consumption for estanques. If the pond includes instalación eléctrica for bombas (pumps) or iluminación (lighting), a Boletín Eléctrico (CIE) issued by a instalador autorizado is required. Ponds near cauces públicos (public waterways) may require authorization from the Confederación Hidrográfica corresponding to the river basin.
