- Do I need a building permit?
-
As a general rule, you must have permission to build new, build on and rebuild, as well as change the use of existing construction. Smaller buildings (sheds, roofs, carports and the like) do not always have to have a building permit, but they are nevertheless covered by a number of rules.
