Exemption rules - Read the fine print

Read the fine print!

There are many ways to interpret the written word, and this applies to interpreting the legislation. When deciding whether the building works you are planning doesn’t require a building consent, ensure you read and understand the clause in its entirety, especially the however sub-clauses. 

For example, Schedule 1 Pt1 Section 3 – Single storey detached buildings not exceeding 10sqm in floor area – states:

  1. The floor level can only be 1m maximum off the supporting ground, with the building height equal to or less than 3.5m above the floor level.
  2. Is equal to or less than 10m2 floor area.
  3. It doesn’t contain any sanitary fixtures.
  4. If there is no dwelling within proximity of the building, it cannot be used as a sleepout.
  5. The building cannot be closer than its own height away from a residential building or the boundary – refer to cl. (2) of Schedule 1 Pt 1(3)(2)


Therefore, if your detached sleepout is less than 10sqm, is supported on a concrete slab on grade floor, the roof apex is 3m above the floor level, it does not have any plumbing fixtures, is 3.5m from the boundary and 1.2m away from the detached dwelling, then it is not exempt, and a building consent is required.

Reason: the sleepout is not its own height away from the residential building.
