A building permit is required prior to commencing construction for most structures (residential, commercial or industrial) including but not limited to new works, additions, alterations, commercial fit-outs and refurbishments, changes to ground levels, swimming pools, spas and pool barriers. 

Additionally, if you need to demolish a structure (residential, commercial or industrial) you will need a Demolition Permit.

Although Part 6 of the Building Regulations 2012 details building work for which a building permit is not required, it does not exempt those works which may require planning approval.

It is important to consult the permit authority (i.e. Shire of Carnarvon) or a registered building surveyor to ensure you obtain correct advice about the plans and processes you need to follow prior to lodging a permit application.

The Shire of Carnarvon is in the cyclone region of Western Australia, which means everything needs to be built to a structural standard to withstand cyclonic winds.  Carnarvon is in Wind Region D.  For example if you are going to build a shed of any sort, you will need a cyclone kit with Wind Region D specifications.

Property Plan Search

You may be required to provide copies of certified plans of your property’s structures with your application.  The Shire has a library of plans on file. 

Should you require a copy of approved building plans for your property, you can arrange for the Shire to retrieve building archived plans by submitting the Plan Search Request Form and returning it with fee payment.  The fee must be paid before any searches will be carried out.  You can pay by phone; at (08) 9941 0000 option 1, email; building@carnarvon.wa.gov.au or by coming into the Shire office at 3 Francis Street.

Planning Approval Requirements

Anyone who carries out ‘builder work’ valued over $20,000 must be a registered builder or an approved owner-builder before applying to the local government for a building permit. However, there are a number of exemptions where registration is not required. Please refer to 'Do I need to be a registered builder?' publication from the Department of Mines, Industry Regulation and Safety, building and energy consumer information

Owner-builder work consists of the following:

Class 1a (i) building – a single dwelling, is a detached house. This includes an extension to a house or a habitable dwelling on the same property but separate to the main house such as a granny flat;

Class 10 building – being a non-habitable building such as a private garage, carport, shed or the like; or

Small commercial building – is a one or two-storey building with a floor space of less than 500m2 that is not a detached house, Class 10 building or farm building

Under the Building Services (Registration) Act 2011, owner-builders are required to obtain approval from the Building Services Board, administered by the Building Commission, before obtaining a building permit to carry out owner builder work on their land. Applicants are required to provide evidence of their ownership of the land and demonstrate that they have sufficient knowledge of the duties and responsibilities of an owner-builder.
