Do you need a permit for skylight installation? in Polen
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 Poland, installing a roof window (okno dachowe) that does not alter the building's outline or load-bearing structure is usually covered by a notification (zgłoszenie) to the Starostwo Powiatowe rather than a full building permit. However, if the skylight changes the roof's geometry or the building is in a conservation zone (strefa ochrony konserwatorskiej), a full pozwolenie na budowę and heritage authority approval are required. Work must comply with PN-EN 14351-1.
