My Property Look Up

The MBRC Planning Scheme includes Domestic outbuildings as part of the Dwelling house definition. A Domestic outbuilding is defined as:

A Class 10a building, as defined in the Building Code of Australia, that is ancillary to a residential use on the same premises and is limited to non-habitable buildings for the purpose of a shed, garage and carport.  

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 exempt development. Refer to Information sheet about Accepted building work for detailed information about the circumstances when building work is exempt 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:

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, please refer to Temporary accommodation pack on Council’s website.

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.
