MBRC Planning Scheme - Domestic outbuildings (sheds & carports)

Domestic outbuilding means a non-habitable class 10a building that is:

  1. a shed, garage or carport; and
  2. ancillary to a residential use carried out on the premises where the building is.

The advice provided in this information sheet relates to Domestic outbuildings, including all Class 10a buildings as defined in the Building Code of Australia.

Do I need Council approval?

A Domestic outbuilding (where a Dwelling house is already on the property) that is 50m2 or less may be accepted development. Refer to the information sheet about Accepted building work for detailed information about the circumstances when building work is accepted development.

If the Domestic outbuilding does not comply with the circumstances for being accepted development, it will be accepted development subject to requirements. Meaning, approval from Council is not required provided the building work complies with the requirements in the relevant code(s) in the planning scheme.

If the Domestic outbuilding does not comply with the requirements in the relevant code/s either of two things is required:

  • if the proposed Domestic outbuilding does not comply with the criteria in the Dwelling house code, a concurrence agency response will be required from Council;
    OR
  • if the proposed Domestic outbuilding does not comply with the criteria in the relevant zone code, a development application must be lodged with Council for approval.

Development approval will be required from Council if the Domestic outbuilding is located in the following zones, overlay maps or areas:

  • Centre zone
  • Community facilities zone - all precincts except for the Abbey precinct
  • Environmental management and conservation zone
  • Extractive industry zone
  • Industry zone
  • Limited development zone
  • Recreation and open space zone
  • Township zone - Centre, convenience and industry precincts
  • Overlay map - Coastal hazard (High risk and Medium risk storm tide inundation areas)
  • Overlay map - Coastal hazard (Erosion prone area)
  • Overlay map - Flood hazard (High risk and Medium risk flood hazard areas)
  • Drainage investigation area identified on Figures 8.2.2.1 to 8.2.2.10 of the Flood hazard overlay code

Planning Scheme requirements

The requirements for Domestic outbuildings vary depending on the zone and precinct of the property. These requirements are summarised below in two groups:

  • General Residential and Emerging Community zone requirements
  • Rural Residential, Rural, Emerging community and Township zone requirements

If the proposed Domestic outbuilding is located in an area of the property identified on an overlay map, the planning scheme requirements may be different. Overlay maps that may have additional requirements, or alter the below requirements, include but are not limited to Environmental areas, Bushfire hazard, Landslide hazard, Riparian and wetland setbacks, Flood hazard and Coastal hazard. These additional requirements are found in the relevant code under the ‘Values and constraints criteria’ and Part 8 Overlays and are summarised below.

General Residential and Emerging Community zone requirements

Requirements for Domestic outbuildings in the following zones and precincts are found in the Dwelling house code (section 9.3.1):

  • General residential zone (all precincts)
  • Emerging community zone - Transition precinct (developed lot)
  • Redcliffe Kippa-Ring local plan - Interim residential precinct
  • Caboolture West local plan - Urban living precinct (Next generation neighbourhood sub-precinct)

The Dwelling house code includes the following requirements for Domestic outbuildings in these zones and precincts:

Type Requirements (General Residential and Emerging Community zones)
Maximum roofed area*

The maximum roofed area varies depending on the size of the property/lot:

  • Size of lot is less than 600m - Maximum roofed area is 50m2

  • Size of lot is >1000m2 to 2000m2 - Maximum roofed area is 80m2
  • Size of lot is greater than 2000m2 - Maximum roofed area is 150m2
Roofed area is defined in the planning scheme as “The area of the roof of each building or other structure as projected onto a horizontal plane”. Meaning the total combined roofed area of proposed and existing domestic outbuildings in the property.
Maximum building height

For a domestic outbuilding that is a carport and where located in front of the main building line - maximum of 3.3m and a mean height not exceeding 2.7m.

For all other instances, maximum of 4m and a mean height not exceeding 3.5m.
Setbacks
(location on the property)

Front setback - For a domestic outbuilding that is a carport - 5.4m (to outermost projection); or if the Dwelling house was built before 2005, not less than the setback to an existing lawfully constructed carport or garage on an adjoining lot having the same road frontage (where a lawfully constructed carport or garage is located on both sides, the lessor of the two is applicable), or 0.5m whichever is the greater.

For all other instances - 5.4m (to outermost projection) and located behind the main building line and not within the primary or secondary frontage or trafficable water body setbacks.

Side and rear setbacks - In accordance with the Queensland Development Code (QDC). The total combined length of structures built to the boundary may exceed 9m as prescribed in the QDC in some zones and precincts (refer to Table 9.3.1.7 of the Dwelling house code for further information).

Setback to laneway - 0.5m (to outermost projection)

Setback to canal - 4.5m (to outermost projection)

Note - Greater setbacks may be required if the lot adjoins an environmental corridor or area (Refer to Overlay map information below or Values and constraints criteria in the Dwelling House code for details).

Site cover*

The maximum site cover* varies from 40% to 75% depending on the zone and precinct, the size of the property and the height of the building/s on the property. Refer to RAD5 of the Dwelling house code for site cover requirements.

* Site cover includes all components of the dwelling house, including existing and new/proposed site cover of the main dwelling house, domestic outbuildings and secondary dwelling. Site cover excludes eaves, sun shading devices, patios, balconies and other unenclosed structures.

Earthworks (outside of the external walls of the domestic outbuilding) Refer to RAD15 of the Dwelling house code for requirements relating to earthworks where outside of the external walls of a domestic outbuilding.

Non-compliance with the abovementioned provisions will require a concurrence agency response from Council.

Rural Residential, Rural, Emerging community and Township zone requirements

  • avoid single-plane slabs and benching; and
  • ensure the height of any cut or fill, whether retained or not, does not exceed 900mm. 
Associated vegetation clearing   The Domestic outbuilding does not require clearing or damage to a habitat tree.

Overlay maps requirements

The following additional requirements may apply if the Domestic outbuilding is located within the specified feature of an overlay map.

Non-compliance with the abovementioned provisions will require a development application be lodged with Council for approval.

What if there is no dwelling house on the property?

Where there is no dwelling house on the property, the construction of a Domestic outbuilding is only permitted when a temporary accommodation approval has been granted by Council. The planning scheme exempts Dwelling house and Domestic outbuilding, if undertaken under a local law approval for the establishment or occupation of a temporary home e.g. temporary accommodation. For information relating to Temporary accommodation under Council’s Local Law, refer to Building approval - Temporary accommodation.

Where there is no dwelling house on the property, and the construction of the Domestic outbuilding is not associated with a Temporary accommodation approval, either an alternative definition would be applied from the planning scheme based on the intended use of the building or the development would be considered undefined. In both instances an assessable (Impact assessment) application will most likely be required.

It should be noted that for sheds ancillary to an approved Rural use (e.g. cropping, rural industry, intensive animal industry, etc.), the above information does not apply as the sheds are directly associated with the approved use onsite and not defined as a Domestic outbuilding.
