Do You Need a Permit for Bathroom Ventilation Fan Replacement? in Nederland
Sometimes. A simple like-for-like swap of a bathroom exhaust fan on an existing circuit is typically exempt from permits. However, installing a fan where none existed, running new ductwork to the exterior, upsizing the electrical circuit, or cutting a new roof or soffit penetration usually triggers an electrical or building permit and inspection.

Country-specific detail
In the Netherlands, replacing a badkamerventilator (bathroom fan) with an equivalent unit on the existing elektrische installatie is generally vergunningsvrij (permit-free) under the Omgevingswet as inpandig onderhoud (interior maintenance). However, if the work involves a new dakdoorvoer (roof penetration) or gevelopening (facade opening) for ductwork, an omgevingsvergunning may be required, especially in a beschermd stadsgezicht (protected cityscape) or monumentaal pand (listed building). All electrical modifications must comply with NEN 1010 and be performed by a erkend installateur. In appartementen, the Vereniging van Eigenaren (VvE) must approve modifications to the gemeenschappelijke ventilatiesysteem (shared ventilation system).
