Front setback rules in NSW: minimum distances under the Housing Code and council rules

Under the Housing Code, the minimum front setback for a new house in New South Wales is 4.5 m on a lot of more than 300 m² and up to 900 m²¹. It is 3 m on a lot of 200 m² to 300 m², 6.5 m on a lot of more than 900 m² and up to 1,500 m², and 10 m on a lot of more than 1,500 m².

The setback is measured horizontally from the lot boundary to the building line, which is the external wall of the house closest to the primary road. The primary road is the road the front of the house faces¹. Eaves, an entry porch and a garage are dealt with separately, so the 4.5 m figure is measured to the main wall of the house.

These lot-size setbacks apply where fewer than two houses are within 40 m on the same side of the primary road. If two houses are within 40 m, the average of their front setbacks becomes the minimum instead¹.

The Housing Code covers a one- or two-storey house on a lot of at least 200 m² that is at least 6 m wide at the building line, in specified residential and village zones¹. A design that does not meet every standard in the code is assessed through a development application, where the council's planning controls apply instead².

The general setback article covers the side and rear values and the buildable area the three setbacks leave.

In a Greenfield Housing Code area, the minimum front setback is 4.5 m for a house on a lot of more than 300 m², and 3 m on a lot of 200 m² to 300 m²¹. The area in front of the main building line that can contain features such as a porch is set back 3 m on a lot of more than 300 m² and 1.5 m on a lot of 200 m² to 300 m².

The Greenfield Housing Code applies to land inside the mapped Greenfield Housing Code Area¹. The Department of Planning, Housing and Infrastructure states that the code commenced on 6 July 2018. Since 6 July 2021, complying development in these mapped areas has used the Greenfield Housing Code rather than the standard Housing Code³.

The legislation uses 300 m² as the lot-size boundary between the 3 m and 4.5 m front setbacks. The department's November 2022 summary table shows a different boundary of 250 m²³. The figures in this article use the requirements in the legislation.

In specified inland council areas, the Inland Code applies instead of the Housing Code. It does not apply to land covered by the Greenfield Housing Code. For houses in its residential zones, the Inland Code sets a front setback of 3 m on a lot of 200 m² to 300 m², 4.5 m on a lot of more than 300 m² and up to 1,500 m², and 10 m on a lot of more than 1,500 m². Neighbour averaging also applies under this code¹.

For a development application, the council's development control plan sets the front setback. The three plans reviewed set front setbacks of 4.5 m to 6 m for a house on a lot of 900 m² or less.

Camden Development Control Plan 2019 sets 4.5 m on a lot of 900 m² or less, 6.5 m on a lot of more than 900 m² and up to 1,500 m², and 10 m on a lot of more than 1,500 m². It uses the same neighbour-averaging rule as the Housing Code. Where a house fronts open space, the setback can be 3.5 m⁴. Camden measures the setback from the main wall closest to the boundary and allows an architectural element to extend up to 1.5 m into the setback where it improves the streetscape.

Blacktown Development Control Plan 2015 sets a 6 m front setback for a house in the residential areas it covers, with a 1 m encroachment allowed for an architectural feature. In Stanhope Gardens, the setback is 4.5 m⁵. A garage, carport, awning or shed also generally has a 6 m setback, although a smaller setback may apply where the garage is compatible with adjoining development.

The Blacktown City Council Growth Centre Precincts Development Control Plan 2010 covers parts of the North West Growth Area. For a front-accessed lot 9 m to 15 m wide it sets 4.5 m to the building facade line and 3 m to the articulation zone, or 3.5 m where the facade fronts open space or drainage land. The garage line sits 5.5 m from the road and 1 m behind the building line⁶.

In some cases, front setbacks set when the land was subdivided can replace the standard table values. These setbacks can be recorded against the lot title, while the 5.5 m garage setback still applies⁶.

These council plans apply to the development application path, not complying development. Blacktown Development Control Plan 2015 notes that where a house meets the requirements for complying development, the state code's setbacks apply instead⁵.

Estate design guidelines can add another set of requirements. The Elara Design Essentials for the Frontier release at Marsden Park, from March 2016, defer setbacks to the NSW Housing Code or the council's plan, require an entry feature in front of the main building line, and require Stockland's endorsement of the home design package before planning approval is sought⁷. The version attached to a lot's contract of sale applies to that lot.

The design guidelines article covers what estate covenants control and where to get a lot's copy.

The front setback for a block can depend on the state code, the lot and neighbouring houses, and any council or estate requirements that apply.

• State code and approval path. The NSW Planning Portal's Spatial Viewer shows a lot's zone and whether it sits inside the Greenfield Housing Code Area, the map layer the department publishes for Part 3C⁸. A lot inside that area uses the Greenfield Housing Code, while a lot outside the greenfield and inland areas uses the Housing Code. If a design does not meet the requirements for complying development, the council's planning controls apply through a development application.
• The lot and its neighbours. The lot area determines the standard setback, while under the Housing Code and Inland Code, the average setback of the two nearest houses within 40 m on the same side of the road can apply instead.
• Council, title and estate requirements. A building envelope recorded on the title or estate design guidelines can set additional or different requirements. For a development application, council planning controls can also affect the setback.
