Is a permit required to build a garage?

Mr Inspector conducts pre-purchase building inspections Melbourne wide and is often asked by clients about what they require a building permit for.

Schedule 8 of the Building Regulations 2006 lists items where are Building Permit is not Required.

I will endeavour to summarize schedule 8 in regard to the queries I often receive in relation to Garages.


Class 10a buildings are typically Garages and sheds and are non-habitable buildings.

A permit is not required in relation to free standing Class 10a Buildings that;

a) Have a floor area not exceeding 10 square meters and

b) is no more than 3 meter high or, if situated within 1 meter of a boundary, is no more that 2.4 meters high and

c) is appurtenant to a building of another class on the same allotment, and

d) is located no further forward on the allotment than the front wall of the building to which it is appurtenant; and

e) is not constructed of masonry.

From this you can see there are some restrictions on when a permit is required for a class 10a building, e.g. a garage.

Building with bricks and you will require a permit.  Building it with a floor area greater than 10 m square and you will require a permit.

Over 3 meters high and you will require a permit. If it is within 1 meters of a boundary and greater that 2.4 meters high, you will require a permit.


The exemptions on requirements for obtaining a permit are found in schedule 8 of the Building Regulations 2006 which can be readily found on the internet.  These exemptions relate to fences, demolition, alterations to a building, underpinning, re-stumping, increasing floor areas, swimming pools and the list goes on.  Mr Inspector will endeavour to add more examples to his blog in the near future to assist you.
