Definition

An outbuilding means an enclosed non-habitable building detached from a house, such as a shed, detached garage or studio, but does not include a pergola, patio, carport or stable (where the stable is associated with an approved ‘Rural Pursuit’). Outbuildings are classed a 10a building.

What is permitted

Acceptable outbuilding designs will vary depending on the zoning and lot size.

Planning approval may be required (before a building permit) where a proposal does not comply with the standards prescribed under Local Planning Scheme No.4, or is specifically identified as requiring approval. 

In all cases planning approval would be required for building an outbuilding:

  • Before a single house has been built on the lot
  • In front of a single house
  • On land with a slope over 20%, or sand pad above 0.5m
  • within the Flood Prone Special Control Area
  • Within 20m of the banks of a watercourse in a Residential zone
  • Within 30m of the banks of a watercourse in other zones
  • On a lot affected by Local Natural Area (LNA)
  • On a rural lot where native vegetation is required to be removed; or
  • Does not comply with the tables below.

Under no circumstances will the Shire approve any outbuilding that exceeds the maximum floor area permissible.

Sheds/outbuildings in a bushfire prone area

Sheds and outbuildings proposed within 6 metres of a residence (Class 1a building) are required to be constructed according to Australian Standards 3959-2018 “Construction of buildings in a bushfire prone area” if:

  • The associated residence was constructed during or after 2014; or
  • The proposed building work exceeds $20,000.

Find out more about Developing in a Bushfire Prone Area.

Registered vs owner-builders

Building works valued under $20,000 do not require a registered builder, allowing owners to nominate themselves as “builder” on the building application form.

For building works over $20,000 a registered builder must be nominated as the builder. Owners who wish to appoint themselves as the builder for building works over $20,000 are required to attain an owner-builder certificate from the Department of Mines, Industry Regulation and Safety.

Apply for planning approval and building permit

Step 1. Apply for planning approval

To make an application for planning approval you will need to provide details of the site and the existing and proposed buildings. An application must include:

  • Completed planning application form (see below) signed by all owners and planning application fee (refer to current Shire Schedule of Fees)
  • A copy of the Certificate of Title to show any easements, caveats or other restrictions
  • Site plan (to scale) showing lot boundaries, all existing buildings and effluent disposal systems and the precise location of the proposed outbuilding
  • Floor plans if there are any internal walls
  • Elevations (to scale) of the outbuilding showing colours, materials, wall height and ridge height
  • Details of any earthworks (cut, fill, retaining walls) in relation to the natural ground level (fill will count towards the height of the outbuilding above natural ground level)
  • Environmental Asset Inspection report (if applicable), if lot is affected by a local natural area. Find out more about Environmental Asset Inspections.

Planning Approval Application Form (PDF)

Step 2. Apply for building permit

You will need to complete a Application for building permit – uncertified (BA2).

Ensure you include architectural drawings, including:

  • Site plan
  • Floor plan
  • Elevations
  • Sections
  • Engineering - all structural and construction details certified by a registered Structural Engineer
  • Stormwater Drainage Plan
  • Bushfire Attack Level (BAL) Assessment and Certificate if required.

Refer to Building Permit Fee and Calculator. 

Building permit applications either certified or uncertified are usually assessed and approved within 10 business days.

Building permits are sent to the builder via post.

Step 3: Submit a Notice of Completion

Under the Building Act 2011, the owner or builder must notify the Shire that the work is completed by submitting a BA7 Notice of Completion Form.
