Do You Need a Permit to Remove an Interior Wall? in Spain
Sometimes. Removing a load-bearing wall almost always requires a building permit because it changes the structural system of the house — an engineer must design a replacement beam and the work must be inspected. Non-load-bearing partition walls can usually be removed without a permit, but if plumbing, electrical, or HVAC runs through the wall, those trades may trigger their own permits.
Do you need a permit?

What triggers a permit
- The wall is load-bearing (supports floor joists, ceiling, or roof above)
- Plumbing drain or vent lines run through the wall
- Electrical panel, sub-panel, or main circuits are mounted on the wall
- HVAC ductwork or gas lines pass through the wall cavity
Country-specific detail
In Spain, removing a load-bearing wall (muro de carga) requires a licencia de obra mayor with an architect's project and a structural engineer's calculations. The Código Técnico de la Edificación (CTE) mandates that the replacement structure meet seismic and load requirements. Non-load-bearing partitions (tabiques) typically fall under licencia de obra menor or comunicación previa. In buildings under a comunidad de propietarios, modifying structural elements requires a vote of the community. Historic zones may impose additional heritage review.
