Do You Need a Permit for a Whole-House Fan Installation? in Polen
Sometimes. Installing a whole-house fan typically involves cutting a large opening in the ceiling, modifying attic framing, and running a new dedicated electrical circuit — all of which can trigger building and electrical permits. Some jurisdictions exempt simple replacement of an existing fan on the same circuit, but new installations almost always require at least an electrical permit.

Country-specific detail
In Poland, installing a wentylator całodomowy (whole-house fan) that requires cutting through the strop (ceiling slab) or modifying the konstrukcja dachu (roof structure) is classified as przebudowa (reconstruction) under the Prawo budowlane, requiring a pozwolenie na budowę. If the fan mounts in an existing opening without structural changes, it may qualify as remont (renovation) requiring only a zgłoszenie. The dedicated obwód elektryczny (electrical circuit) must be installed by a person with uprawnienia SEP G1, and the completed installation requires a protokół pomiarów elektrycznych.
