Do I Need a Permit to Install a Smart Lock? in Spanje
Installing a smart lock on an existing door almost never requires a permit. Replacing a standard deadbolt with a smart deadbolt or adding a smart lock to an existing deadbolt prep is considered a hardware swap, not a building alteration. However, permits may be triggered if the installation requires new electrical wiring (hardwired locks needing a dedicated circuit), if you are modifying a fire-rated door assembly, or if the work involves running low-voltage wiring through walls in jurisdictions that regulate low-voltage installations. Renters should check lease terms and landlord approval requirements.

Country-specific detail
In Spain, installing a cerradura inteligente (smart lock) on an existing door in a vivienda (residential property) does not require a licencia de obra or comunicación previa. It is classified as a simple cambio de herraje (hardware change). Battery-powered smart locks require no instalación eléctrica. If a hardwired system requires new cableado (wiring), the work should be performed by an instalador autorizado. In comunidades de propietarios (homeowners' associations), changing the exterior appearance of the puerta de entrada (entry door) in common areas may require community approval. Modifying a puerta cortafuegos (fire-rated door) must preserve its certificación de resistencia al fuego. The Código Técnico de la Edificación (CTE) section DB-SI covers fire safety requirements for doors in shared buildings.
