Queensland house setback rules: front, side and rear distances explained

Queensland's default setback rules depend mainly on the size of the lot. The Queensland Development Code (QDC) uses MP1.1 for a single detached house on a lot under 450 m² and MP1.2 for a lot of 450 m² or more.¹ Both set default front, side and rear setbacks for the house, as well as garages, sheds and carports on the same lot.

Setbacks are measured from the outermost part of the building to the boundary. For a roof, this includes the outside face of the fascia rather than just the wall.¹

The QDC figures are the standard setbacks that can generally be approved without further assessment. A design that does not meet them may still be considered, but it needs to be assessed against broader requirements such as streetscape, daylight, ventilation and neighbour privacy.²

The QDC does not always provide the final setback for a block. A council planning scheme can set different requirements, and different rules can also apply inside a priority development area.³ Estate design guidelines may add another layer of requirements. Where one of these replaces or adds to the state rules, the setback for that block can differ from the QDC default.

For a lot of 450 m² or more, the Queensland Development Code rules generally require a 6 m front setback for a house, garage or carport.⁴

Where houses already stand on both neighbouring lots and at least one is between 3 m and 6 m from the road, a different setback based on the neighbouring houses can apply.

On a corner lot, the second street generally also has a 6 m setback. However, different rules can apply where the average lot depth is 24 m or less. A structure more than 2 m high also cannot be placed within the 9 m by 9 m area at the street corner.

An open carport can sometimes be closer to the road where there is no suitable compliant location elsewhere on the lot. To qualify, the walls and posts inside the setback can make up no more than 15% of the carport's perimeter.

The side and rear clearances are the same as for smaller lots: 1.5 m for parts of the building up to 4.5 m high and 2 m for parts between 4.5 m and 7.5 m high.⁴

Above 7.5 m, the clearance starts at 2 m and increases by 0.5 m for every additional 3 m, or part of 3 m. Smaller clearances can apply on rectangular or near-rectangular lots with a frontage of 15 m or less. Site cover is limited to 50% of the lot. The maximum building height is 8.5 m on slopes up to 15% and 10 m on steeper slopes.⁴

A wall closer than 750 mm to a side or rear boundary must be designed so it does not require access from the neighbouring property for maintenance. Windows and balconies close to a side or rear boundary also need privacy measures such as screening, a high window sill or obscure glazing.

A priority development area (PDA) can have its own setback and building rules instead of the council's usual planning rules.

These areas are generally planned for major housing or development projects. Each PDA has its own development scheme, which sets the rules that apply within its boundary. Economic Development Queensland assesses applications in most PDAs, although councils manage some areas.

Yarrabilba in Logan is one example. Its development scheme uses the QDC setback rules for many detached houses. Lots from 400 to 450 m² generally use the rules for smaller lots, while lots above 450 m² generally use the rules for larger lots.

The scheme also sets some of its own requirements. The maximum building height is 9 m, compared with the QDC's 8.5 m default. It also includes requirements for outdoor living space, covered parking, driveway width and front fencing.

For some houses on lots of at least 400 m² with a frontage of at least 12.5 m, no separate planning application is required where the development meets the scheme's requirements and the lot is outside specified constraint areas.

Yarrabilba covers 2,222 hectares and is planned for about 20,000 homes.⁸ Other major residential PDAs in south-east Queensland have their own development schemes and housing rules.

Estate design guidelines can add extra setback and building requirements on top of the state and council rules. In many south-east Queensland estates, the exact setbacks for a block are shown on a separate plan issued for that lot rather than in the public design guidelines.

For example, Yarrabilba and Springfield Rise both refer to lot-specific setback plans provided with the sales documents.¹² Flagstone also requires homes to comply with the development scheme, the relevant lot plan and conditions in the contract.¹³

North Harbour publishes more of its setback rules. For lots under 450 m², the house generally has a 3 m front setback, while a double garage needs 4.5 m and a single garage 5.5 m. The secondary-street setback is 2 m. The guidelines also allow a boundary wall on one side of the lot, with a 1.5 m setback on the other side. On lots up to 27 m deep, the rear setback is 3 m. Deeper lots, and lots of 450 m² or more, need a 4.5 m rear setback.¹⁴

A two-storey part generally needs a 2 m side and rear setback. Boundary walls can be up to 15 m long and 3.5 m high. On frontages under 13 m, the 1.5 m side setback can reduce to 1 m in some cases.¹⁴ Estate guidelines can also measure setbacks differently. Aura and North Harbour measure from the wall or posts¹⁵, while some Flagstone guidelines measure from the outer edge of the building, including the roof.¹³

Boundary-wall rules also vary between estates. Harmony requires the wall to sit at least 200 mm inside the boundary¹⁶, SkyRidge allows 200 mm to 400 mm¹⁷, and Yarrabilba allows 50 mm to 200 mm.¹²

The setback rules for a block can come from several different layers: the state rules, a priority development area or council planning scheme, and any estate-specific requirements.

The lot size determines which state rules apply, while the street type can affect the front setback for smaller lots. If the lot is inside a priority development area, its development scheme can set different requirements. Outside these areas, the council planning scheme can replace some of the state defaults with local rules.

In an estate, a lot-specific setback plan or development plan can add another layer of requirements. Some of these plans are issued with the sales documents and are not publicly available. BuildStreet checks these rule layers in order: the state rules first, then any priority development area or council requirements, followed by the estate rules where available. Where a lot-specific estate plan is not public, the setback result is treated as needing further siting information rather than being shown as a confirmed fit.
