Do You Need Council Approval for Your Landscaping Project? Here's How It Actually Works

By Manna Landscapes | September 2026

Not every landscaping project needs the council's sign-off, but some do, and it's not always obvious which is which. Chuck in a new garden bed and nobody's going to blink. Put up a retaining wall, add a pool, or mess with the levels on your block, and that's a different story.

For a lot of homeowners, this is where a landscaping project starts to feel like a headache, not because the design's hard, but because the process around it is murky. So here's a straight-up look at how council approval actually works, and what it means for you.

What Usually Sets Off the Need for Approval

Council approval isn't needed for every project, but a handful of things tend to trigger it, including:

• Retaining walls over a certain height
• Swimming pools and pool fencing
• Bigger changes to site levels or drainage
• Structures like pergolas, decks, or outbuildings over a certain size
• Work near heritage items, bushfire-prone land, or environmentally sensitive areas

It varies by council and by site, which is exactly why it's worth checking early rather than assuming your project's exempt.

Why Checking Early Actually Matters

The real risk isn't the approval process itself, it's finding out halfway through a project that something needed sign-off you didn't see coming.

Checking early means the design gets shaped around what'll actually get approved from the start, instead of needing a rework further down the line. It also protects your timeline. Approvals take time, and factoring that in upfront saves you from delays once the diggers are already on site.

What the Process Actually Looks Like

Depending on how big the project is, approval might come through a fairly straightforward pathway, or it might need a more detailed application to council. Generally, it goes something like this:

1. Working out what's needed. Figuring out whether approval's required, and which pathway fits.
2. Getting the documentation together. Site plans, drawings, supporting reports, depending on what's being built.
3. Submitting it. Either straight to council, or through a private certifier where that's an option.
4. Waiting it out. Timeframes shift around, but this is usually where delays creep in if the paperwork wasn't right the first time.
5. Getting the green light before anything starts. Any structural or major landscape work generally can't kick off until this step's done and dusted.

Where Having a Landscaper on Your Side Helps

This is where a lot of the stress can come off a homeowner's plate.

A landscape design process that factors in approvals from the get-go means the paperwork's right the first time, and the design itself is shaped with compliance in mind rather than needing changes after the fact.

For residential landscaping projects involving retaining walls, pools, or bigger site changes, having a team that handles this end to end means you're not stuck interpreting council requirements yourself, or juggling between a designer and a separate consultant just to get the paperwork sorted.

So, What Does This Mean for Your Project?

Council approval doesn't need to be a source of stress, or a reason to keep putting things off. It just needs to be part of the plan from day one, not something you deal with after the design's already locked in.
