Do I Need a Permit to Build a Deck? in Poland
Deck construction requires a building permit in most US jurisdictions regardless of size, because it involves structural footings and may affect lot coverage. EU rules are more lenient for low, freestanding platforms but tighten when the deck is attached to the house, elevated, or roofed. Unpermitted decks fail home inspections and can trigger mandatory demolition.

Country-specific detail
Polish freestanding terraces (tarasy) up to 35 m² and under 2.5 m in height require only a notification (zgłoszenie). Larger decks, elevated structures, or those attached to the building's structural walls require pozwolenie na budowę. Terraces that increase the building's footprint (zabudowa) count toward the lot coverage ratio in the MPZP. Decks on agricultural land (działka rolna) face additional conversion requirements if the land hasn't been reclassified (odrolnienie).
