What it means for the owner
- The list also covers small outbuildings, garden arrangements, solar panels within set limits and replacing window frames with more efficient ones of the same look (art. 6.º-A n.º 1).
- A municipal regulation can classify other works as minor and set limits beyond those in the law (art. 6.º-A n.º 1 i) and n.º 3).
- They do not apply to listed buildings or their protection zones, apart from the window-frame case (art. 6.º-A n.º 2).
- Exempt works still have to follow the plans and technical rules, can be inspected, and need the start-of-works notice (art. 6.º n.º 8 and n.º 12).
