Do you need a permit for skylight installation? in Spanje
Usually yes. Installing or replacing a skylight almost always requires a building permit because it involves cutting or modifying the roof structure, altering waterproofing, and potentially changing egress. Inspectors verify structural framing, flashing, and energy-code compliance. Work without a permit can void roof warranties and create insurance problems.

Country-specific detail
In Spain, skylight installation requires a licencia de obra menor from the Ayuntamiento. The project must comply with the Código Técnico de la Edificación (CTE), specifically Documento Básico HE (energy savings) and HS (waterproofing). In Bienes de Interés Cultural (BIC) or historic town centres, additional approval from the comunidad autónoma's heritage department is required. A certified architect (arquitecto técnico) must supervise installations that alter structural elements.
