Do You Need a Permit to Remove an Interior Wall? in Polen
Sometimes. Removing a load-bearing wall almost always requires a building permit because it changes the structural system of the house — an engineer must design a replacement beam and the work must be inspected. Non-load-bearing partition walls can usually be removed without a permit, but if plumbing, electrical, or HVAC runs through the wall, those trades may trigger their own permits.

Country-specific detail
In Poland, removing a load-bearing wall (ściana nośna) is treated as a structural alteration (przebudowa) under Prawo Budowlane and requires a building permit (pozwolenie na budowę) with a structural engineer's design. The project must include a new load distribution scheme, and a construction supervisor (kierownik budowy) must oversee the work. Non-load-bearing partition walls (ściany działowe) can typically be removed under a notification (zgłoszenie) or without any formality, depending on whether the work changes the building's layout as recorded in the użytkowanie documents.
