Building Permits

What is a Building Permit?

A building permit is an official document that certifies that a relevant Building Surveyor has given approval to plans and documentation before building activity commences.

The building permit is required for most building work (see information below) and ensures buildings comply with the Building Code of Australia, the Building Act 1993 and Building Regulations 2018 for the purpose of ensuring the safety of those constructing the structure, those using the structure and those who will be around the structure.

What if building work has been completed without a Building Permit?

Your local council has a responsibility to the community to ensure the built environment is safe for use and/or occupation. This includes investigating unsafe or illegal buildings and issuing the appropriate Notice or Order to resolve the issues.

Where council finds work carried out without a permit the council will take steps to achieve a reasonable result for both parties.

The first step is issuing a Building Notice asking the property owner to ‘show cause’ why certain actions should not be carried out.

When the owner does not respond to a Building Notice or does not respond adequately, the Municipal Building Surveyor may issue a Building Order with direction to carry out work to ensure the works comply with building regulations.

An Emergency Order may also be issued by the Municipal Building Surveyor where a danger to life or property exist because of the conditions or proposed use of a building.

When an owner fails to comply with a Building Order or Emergency Order, the Municipal Building Surveyor is empowered to initiate prosecution. Building work completed without a Building Permit is in contravention of Section 16(1) of the Building Act which carries fines of up to $72,180 for a natural person.

From the perspective of an insurance claim, a building permit provides you with evidence that the construction has been checked by a registered building practitioner to ensure it has been completed in accordance with relevant codes and standards. If your building structure is damaged, or a person is injured because of an illegal building addition or alteration you may find your insurance company may not cover your claim.

When a home with illegal building additions or alterations is sold, the buyer of the home assumes responsibility for the illegal building work, therefore due diligence in this area is necessary.

Building Permit History

Throughout the course of their inspection, your Venatic inspector may identify alterations or additions that have been completed on the property and comment on their condition at the time of inspection. Your inspector is not qualified to advise whether these alterations or additions have been approved by way of a building permit however there are a number of avenues to find further information.

If there has been any building work on the home that has been completed under a Building Permit in the las seven (7) years; the Section 32 Vendors Statement will include a copy of any Building Permits and a copy of the associated Home Owner Warranty insurance.

Under Regulation 51 of the Building Regulations 2018 your conveyancer may also request information on Building Permits from the local council to confirm if any alterations or additions to the home were completed under an appropriate Building Permit. It is important to note that the council may not be able to locate a record of all documents relating to the home particularly if it is an older home or located in an outlying area.

Another option for further protection that is becoming increasingly common is for buyers to take out Title Insurance which protects against illegal or unapproved building works, unpaid rates and encroachment.
