Building a house in Victoria can be a rewarding experience, but navigating the state’s building regulations is crucial for a smooth construction process. Understanding the setback requirements and adhering to the local council’s guidelines will help you streamline the process of obtaining your building permit.
Setbacks play a vital role in maintaining the balance between your property development and its surrounding environment. It’s essential to comply with the local council’s setback requirements in order to prevent any potential disputes or issues with neighbours and authorities.
Understanding Building Setbacks
Determining Street Setbacks
Street setbacks are decided by councils, typically based on the characteristics of the road. These distances can vary depending on road zones, front streets, or side streets. In Victoria, the residential development standards, including ResCode A3 and B6 Street setbacks, help ensure consistent application across planning schemes.
The Purpose of Street Setbacks Regulations
Councils enforce street setback regulations for several reasons:

- Neighbour Considerations: Setbacks help protect neighbours from construction inconveniences and maintain their rights to privacy, ventilation, and light. They also minimise the risk of a collapsing building damaging nearby properties in case of disasters.
- Parking Space Provision: Street setbacks aid in providing adequate parking for residents, preventing street congestion and obstructions for other road users.
- Utility Line Accommodations: Having a street setback ensures there is enough space for utility connections, including water, sewerage, and electricity lines.
- Aesthetic Appeal: Regulated setbacks contribute to an area’s visual appeal by promoting uniformity and reducing clutter.
Keep these factors in mind when planning a building project to ensure adherence to local regulations while considering the interests of neighbours and the surrounding community.
Why Setback Requirements Matter in Property Development
Setback Requirements for Allotments with Buildings on Both Sides of a Street
If your property is located in an area with buildings on both sides of the street, you should maintain the same setback as your neighbours. For example, if their setback distances are 7m and 8m, your setback should be the average ([7m+8m]/2=7.5m). This ensures consistency in the neighbourhood and follows regulations in Victoria.
Setback Requirements for Allotments Next to a Building on a Street with No Construction on the Opposite Side
If your property is next to a building on a street without construction on the opposite side, maintain the same setback distance as the existing building. This helps keep the neighbourhood cohesive while also following local regulations.
Allotment Where No Buildings Exist on Either Side of the Street
For properties where no buildings are present on either side of the street, maintain a setback of 6m on a Category One Road Zone road and 4m on any other type of street. This ensures adequate space between your construction and the street while adhering to local regulations.
Corner Allotments
The regulations for corner allotments depend on whether there is a building on the opposite side of your property.
Main or Front Street (The Street the House Address is Under)
If there is a building on the abutting land, maintain the same distance from the street as the existing building. The minimum allowable setback distance for corner allotments is also 9m. For properties without a building on the corner, maintain a setback of 6m for Category One Road Zones roads and 4m for all other types of roads.
Side or Secondary Street
As per Clause 54, the minimum allowed setback distance is 2m for an allotment with one building. Clause 55 prescribes a minimum of 3m for properties with two or more buildings.
Local Councils May Set Their Own Setback Criteria
Bayside City
In Bayside City, setting the building setback distance depends on the size of your property.
If your property’s width measures under 12.5m, adhere to the setback distance observed by neighbouring properties or comply with a 6m setback, whichever is lesser. Factors influencing side setbacks include:
- Development patterns
- Visual impact
- Natural light
When your plot spans more than 12.5m in width, ensure a 6m setback or align with the existing street distance. For constructions exceeding two storeys, the council may require a greater setback distance.
Corner allotments in Bayside City necessitate a minimum 3m setback.
Side and Rear Setbacks
The side and rear setbacks aim to maintain an adequate distance between dwellings on adjacent lots, especially above the ground floor level. According to ResCode’s A10 and B17 standards, new buildings that are not on or within 200 mm of a boundary should follow specific setback guidelines.
If the side or rear boundary setbacks are not specified in the zone schedule, you can calculate the setback using the below formulas based on wall height:
- For wall heights between 3.6 meters and 6.9 meters: Setback = 1 metre + (0.3 metres x (wall height – 3.6 metres))
- For wall heights above 6.9 meters: Setback = 1 metre + (0.3 metres x (6.9 meters – 3.6 meters)) + (1 metre x (wall height – 6.9 meters))
There are a few exceptions to these setback rules. Sunblinds, verandahs, porches, eaves, fascias, gutters, masonry chimneys, flues, pipes, domestic fuel or water tanks, heating or cooling equipment, or other services can encroach up to 0.5 meters into the specified setbacks. Additionally, landings with an area no larger than 2 square meters and less than 1 meter high, stairways, ramps, pergolas, shade sails, and carports are also allowed to encroach into the setbacks.
For example, if a wall has a height of 6.9 meters, you would calculate the required setback as follows:
1 metre + (0.3 x (6.9 meters – 3.6 meters)) = 1 metre + (0.3 x 3.3 meters) = 1 metre + 0.99 meters = 1.99 meters (rounded up to 2 meters) setback.
By adhering to these guidelines for side and rear setbacks, you can ensure that your building project respects the existing or preferred neighbourhood character and limits the impact on the amenity of existing dwellings.
How Close Can You Build to the Boundary In Victoria?
When constructing a building in Victoria, the minimum distance from the boundary depends on the height of the structure. For buildings with a maximum height of 3.6m, the setback distance must be at least 1m. As the building height increases between 3.6m and 6.9m, the setback distance must increment by 0.3m for each metre of height. For structures taller than 6.9m, the setback moves back 1m for every metre increase in height. Bear in mind the importance of adhering to these regulations when planning your construction project.
Regularly Raised Inquiries
Recognising Setbacks
To identify a setback, measure the distance at a right angle from your property boundary to the wall of your house. Conduct this process for the front, sides, and rear of your property to establish the setback distances.
Measuring Setbacks Accurately
Setbacks are calculated from the outer wall of your home rather than the eaves or roofline. Porches and verandas are not considered part of the structure’s front. Instead, commence measuring from the first external wall of your home.
Frequently Asked Questions
What do residential zones typically require for setbacks?
In residential zones, setback requirements can vary depending on your location and local council regulations. Generally, you must maintain a specific distance between your building and the property boundaries, including front, side, and rear boundaries. These distances are in place to account considerations such as safety, privacy, and aesthetic purposes.
Can side and rear setback distances change by location?
Yes, side and rear setback distances can vary depending on your specific location. Local council regulations and site-specific factors, such as the size and shape of your property, may affect the required setback distances for side and rear boundaries. Always check with your local council to obtain accurate information on setback requirements for your area.
Are there specific setback guidelines for corner blocks?
Corner blocks may have unique setback requirements due to the presence of two street frontages. In most cases, the primary and secondary street frontage will have different setback requirements to account for street visibility and appearance. It is essential to consult your local council’s regulations to ensure you meet the guidelines for corner blocks.
How do front and rear boundary setback rules differ?
Front and rear boundary setback regulations may differ due to the impact on street appearance, access, and privacy. Front setbacks usually consider factors such as the street context and aesthetic value, while rear setbacks are often more concerned with privacy and providing suitable outdoor living spaces. Again, consulting your local council’s regulations is crucial for determining the exact requirements for your property.
When a property is over 450 square meters, what are the regulations?
For properties larger than 450 square meters, setback requirements may differ depending on factors such as the zoning regulations, property size, and existing structures. Larger properties often have more flexible setback requirements due to the potential for larger buildings and more extensive outdoor living spaces. To determine the specific regulations for your property, consult your local council.
What aspects influence setback rules in Victoria?
In Victoria, setback requirements are influenced by several factors, including the property’s location, zoning, size, and shape. Other aspects to consider include safety, privacy, streetscape appearance, and the potential impact on neighbouring properties. Consulting with local councils and SQM Architects can provide tailored guidance and assistance for your property and its setback requirements.
