Do You Need a Permit to Replace Gutters? in Spanje
Rarely. Replacing existing gutters and downspouts on a residential home is classified as routine exterior maintenance in most jurisdictions and does not require a building permit. The work replaces like-for-like components without altering the roof structure, foundation drainage, or stormwater management system. However, permits may be needed if the project changes the size or routing of downspouts in a way that redirects stormwater onto neighboring properties or into the municipal storm sewer, if the home is in a historic district with exterior-alteration review requirements, or if the work includes structural fascia repair that goes beyond simple board replacement.

Country-specific detail
In Spain, replacing gutters (canalones) and downspouts (bajantes) is generally classified as a obra menor (minor work) or mantenimiento (maintenance) that does not require a licencia de obra. Most Ayuntamientos treat like-for-like gutter replacement as part of the property owner's obligation to maintain the building envelope per the CTE (Código Técnico de la Edificación) DB HS-5 (Evacuación de aguas). In buildings declared BIC (Bien de Interés Cultural) or within a Conjunto Histórico, any exterior modification — including changing gutter material or profile — requires authorization from the Comisión de Patrimonio. In comunidades de propietarios (homeowners' associations), exterior changes affecting the building's fachada require community approval per the Ley de Propiedad Horizontal. Stormwater must be directed to the building's saneamiento system or to the acometida pluvial, not discharged directly onto the vía pública.
