Your garden, their rules:
What council regulations actually mean for your landscaping
If you planted a tree, built a pergola or replaced a front fence seventy years ago, you probably would not have thought much about council planning controls.
Today, landscape planning regulations in Sydney can influence many of the decisions made in a residential garden.
What changed?
The answer is not that councils suddenly became interested in private gardens. It is that our understanding of cities changed.
We learned that trees, drainage, neighbourhood character, biodiversity and built structures do not stop at a property boundary. Each private garden contributes to a much larger urban system.
That is why understanding a site’s opportunities and constraints should come before design.
How we got here
Planning controls did not appear overnight. They developed as cities grew, problems became more visible and governments responded to what had been learned.
| Period | What changed |
| Early 1900s | Landscape planning regulations were narrower and focused mainly on subdivision, buildings, roads and public health. Private gardens were not yet viewed as part of an interconnected environmental system. |
| Post-war growth | Rapid suburban expansion increased development, hard surfaces and pressure on drainage and infrastructure. These changes strengthened awareness that development decisions could create impacts beyond individual properties. |
| 1970s and 1980s | Concern about heritage loss and environmental impacts became more formally embedded in NSW planning. The Heritage Act 1977 and the Environmental Planning and Assessment Act 1979 established stronger systems for conserving heritage and assessing development. |
| 1990s and 2000s | As cities became denser, matters such as privacy, setbacks, landscaping, deep soil and residential amenity became increasingly embedded in planning and design controls. |
| Today | Climate change, urban heat, biodiversity loss and changing rainfall patterns have made private landscapes even more important. Planning increasingly considers how private development contributes to broader environmental resilience. |
The landscape planning regulations that apply today are the result of accumulated experience.
They reflect what happens when thousands of individual changes are repeated across a suburb, a council area or an entire city.
Your garden is part of a bigger picture
Every planning control has one thing in common.
It responds to an impact that extends beyond a single property.
A mature tree may belong to one homeowner, but its canopy cools the surrounding area. Its roots absorb water. Its flowers and foliage support wildlife. A front fence may sit within one boundary, but it also helps shape the character of the street. A paved courtyard may seem private, yet the amount of water it sheds can affect drains, adjoining properties and the wider stormwater network.
This does not mean every landscape decision requires approval. It means that private gardens and public outcomes are often connected.
Planning controls attempt to balance those realities.
What this means for your garden
Most homeowners encounter landscape planning regulations and controls through ordinary landscape
decisions. The exact rules vary between councils, sites and types of work. However, the reasoning behind them is often consistent.
Trees
The bigger picture
Mature trees do far more than shade a backyard.
Collectively, they cool suburbs, support wildlife, reduce stormwater runoff and shape neighbourhood character. Once removed, their benefits can take decades to replace.
Typical landscape planning regulations and controls
Depending on the council and the tree, controls may apply to:
- Removal
- Significant pruning
- Work within the root zone
- Trees on heritage properties
- Trees within mapped environmental areas
- Trees above a particular size or trunk diameter
Some species may be exempt. Dead, dangerous or invasive trees may also be treated differently.
What this means for homeowners
Do not assume that a tree can be removed simply because it stands within your property. Understand the planning requirements before finalising a design around its removal. A protected tree may need to be retained, incorporated into the design or assessed by a suitably qualified arborist.
Understanding this early can prevent a concept from being built around an option that is not available.
Fences
The bigger picture
A fence affects more than privacy and security.
Its height, material and position influence the relationship between a home and the street. Across many properties, those choices shape the openness, safety and visual character of a neighbourhood.
Typical landscape planning regulations and controls
Controls may relate to:
- Maximum height
- Solid versus open construction
- Front, side and rear boundaries
- Corner lots and sightlines
- Heritage conservation areas
- Materials and finishes
- Retaining walls integrated with fencing
A fence that appears minor may still require closer consideration if it fronts a public street or sits within a heritage conservation area.
What this means for homeowners
A standard fencing solution may not be suitable for every property. Review the council’s planning requirements before selecting the final height, material or level of enclosure.
This is especially important where privacy needs, sloping land or retaining walls make the proposed fence more complex.
Front gardens
The bigger picture
A front garden belongs to one property, but it contributes to the experience of the whole street.
Vegetation, paving, parking, walls and fences all influence neighbourhood character. Front gardens also play an important role in urban canopy, stormwater management and the transition between public and private space.
Typical landscape planning regulations and controls
Controls may influence:
- The amount of soft landscaping
- Deep soil zones and tree planting
- Driveway width
- Parking within the front setback
- Removal of existing vegetation
- Front walls and fences
- Changes to levels
- Heritage and streetscape character
The requirements are often stricter where the property sits within a heritage conservation area.
What this means for homeowners
A front garden should not be designed as an isolated forecourt. Its relationship to the house, adjoining properties and the street matters.
A proposal that replaces most of the garden with paving, parking or high walls may conflict with planning objectives, even when it appears practical for the owner.
Understanding these constraints early makes it easier to find a solution that works for both the property and its setting.
Pergolas, decks and other structures
The bigger picture
Outdoor structures change how a garden is used, but they can also affect neighbours.
Height, scale and location may influence privacy, overshadowing, drainage and the perceived bulk of development. A structure may feel lightweight within the garden while still having a significant planning impact.
Typical landscape planning regulations and controls
Controls may apply to:
- Pergolas
- Decks
- Covered outdoor areas
- Privacy screens
- Retaining walls
- Pools and pool surrounds
- Sheds and studios
- Changes to ground levels
Some work may qualify as exempt development where it satisfies the applicable standards. Other work may require approval because of its size, location, site conditions or relationship to adjoining properties.
What this means for homeowners
Do not rely on the name of the structure alone.
A pergola is not automatically exempt. A deck is not automatically minor. The relevant question is whether the proposal satisfies the applicable standards for that site.
Setbacks, height and overlooking should be considered before the structure becomes central to the design.
Common misconceptions
Landscape planning regulations and controls are often misunderstood because homeowners naturally view the garden as private property. That perspective is understandable, but it can also lead to costly assumptions.
“It’s on my land, so I can do what I like.”
Ownership does not remove your obligation to landscape planning regulations. Councils can regulate work that affects trees, drainage, heritage, neighbours or the wider environment.
“My neighbour already did the same thing.”
A nearby project is not proof that the same work is permitted on your site. The properties may have different zoning, heritage status, lot conditions or approval histories. The work next door may also have been approved under different rules, or completed without approval.
“If approval is possible, the design must be acceptable.”
Approval and good design are not the same thing. Planning controls establish minimum or required standards. A proposal can comply while still responding poorly to the site, the client or the surrounding landscape.
“I’ll check the rules once the design is finished.”
By then, the design may depend on assumptions that cannot be supported. A protected tree, heritage control or drainage constraint can change the direction of an entire project.
Planning research, via tools such as NSW Planning, is most valuable before major design decisions are made.
Wrap up
Landscape planning regulations and planning controls are not random obstacles placed between homeowners and their gardens.
They are the product of decades of learning about how private decisions collectively shape our cities.
Trees influence canopy and habitat. Paving influences stormwater. Fences influence streets. Structures influence neighbours.
The purpose of understanding these planning controls is not to make the design process more complicated. It is to begin with a realistic picture of what the site can support. That knowledge creates better decisions, clearer priorities and fewer surprises later.
Understand the site before designing the solution
A Site Diagnostic identifies the physical, environmental, ecological and regulatory conditions that may influence a landscape project. It helps establish what is possible, where uncertainty remains and what
should be investigated before design begins.
By understanding the site first, the project can move forward with greater clarity and confidence.
Frequently asked questions
Do all landscape projects require council approval?
No. Many landscape works can be undertaken without approval, while others may require consent depending on the type of work, the site’s planning controls and whether the proposal meets exempt development standards.
Can I remove a tree on my own property?
Not always. Many councils protect trees above certain sizes or within particular locations. Always check the applicable controls before planning around tree removal.
Are pergolas and decks exempt from approval?
Some are, but not all. Whether a structure qualifies as exempt development depends on factors such as its size, height, location and the characteristics of the site.
Why do planning controls apply to gardens?
Private gardens collectively influence tree canopy, biodiversity, stormwater management, neighbourhood character and urban heat. Planning controls help balance individual projects with broader community outcomes.
How can I find out which planning controls apply to my property?
The applicable controls depend on your local council, zoning, heritage status and the specific characteristics of your site. Reviewing these requirements early helps avoid redesign later.
Why should planning research happen before the design?
Understanding planning constraints before designing reduces uncertainty, prevents designs being based on unrealistic assumptions and leads to more practical, achievable landscape outcomes.
