Does a building permit cover excavation as well as the slab?

Generally, yes — where excavation is genuinely part of the same overall building works (site preparation for a new slab, for instance), it’s typically covered under the same building permit rather than needing a separate one.

Larger, standalone earthworks unrelated to a specific building permit can trigger their own separate council approval though, so it’s worth confirming exactly what your particular permit scope includes.
