Consultation with the Planning

When building it is often a requirement to seek Planning Approval before applying for a building permit.  The Building Surveyor must be satisfied that the proposed building work has the necessary approval under the Planning and Development Act 2005 and the applicant has complied or is complying with all relevant planning requirements. 

The Town Planner will check for any heritage encumbrances.  They will also check to ensure all building is in line with the R-codes, Zoning and use of the property.

Please contact Town Planning on (08) 9941 0000 for advice on whether a planning assessment or a planning application is required to meet the relevant requirements.  Or see our Town Planning on this website.

Specifications

The plans submitted must include the specifications of materials to be used, including type, rating, size etc.  An Architect, draftsman or engineer will include all required specifications within the proposed build.

Cyclone Wind Rating

The Shire of Carnarvon is located within one of the most severe cyclonic wind regions in Australia.

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

As such, all structures are required to be designed and certified by a practicing certified structural engineer in accordance the Building Code of Australia and Australian Standards. Design wind speeds can be obtained from the Building Code of Australia or the Australian Standards.

The following map is an extract from the Building Code of Australia which shows the locations of all wind regions within Australia.

Wind Regions of Australia Map

Structural Engineer Certification

All structural plans must be signed off by a registered structural engineer confirming that the design meets the requirements for Cyclone Region D

For Non-Sewered Areas

Where the building work will require installation or modification of apparatus for the treatment of sewage, approval under the Health Act must be obtained for this work before a building permit can be issued.  The Shire recommends that a building application is not submitted until such Health approval is granted.  Please complete in full and pay for an 'Application for Construct or Install an Apparatus for the Treatment of Sewage' form.

A site plan is required with the Application for Construct or Install an Apparatus for the treatment of Sewage.  the site plan must show the location and setbacks for all existing and proposed wastewater treatment and disposal systems (e.g. septic tanks and leach drains).  Setbacks are required in relation to boundaries and existing and proposed buildings.

Where an occupancy increase is to occur, the applicant must demonstrate that the existing on-site wastewater system will met Health requirements for the proposed occupancy and may be required to provide full specifications of the existing system (tank types, leach drain types and length etc.)
