(4) Also, a building or building work mentioned in schedule 1, part 1.3 (other than a building mentioned in item 26) is not exempt if building work at the building may affect— (a) the structural integrity of any part of a building for which a certificate under the Act, part 5 (Building occupancy) has been issued; or (b) a fire-rated wall, ceiling or floor; or (c) a ventilation or air-handling system, fire protection system or other mechanical service; or Important concepts Part 2 (d) a fire-escape, emergency lift, stairway, exit or passageway to an exit; or (e) the natural light or ventilation available to a building for which a certificate under the Act, part 5 (Building occupancy) has been issued; or (f) the building in a way that reduces its compliance with the building code to a level that is less than the minimum requirements of the code.
