The Spanish building permit system can be bewildering for foreign clients. Different municipalities have different processing times, different documentation requirements, and different interpretations of the same regulations. Understanding the system — and having an architect who knows how to navigate it — is the difference between a smooth build and months of frustrating delays.
Types of building permits in Spain
Spain has two main categories: licencia de obra mayor for new construction, extensions, and major structural renovations — this requires a full architectural project signed by a licensed architect and technical architect. Licencia de obra menor or comunicación previa for minor works like cosmetic renovations, fence installation, or small modifications — these require less documentation. Your municipality (ayuntamiento) determines which category applies. We prepare the correct documentation package for each type.
