Sometimes. It depends on size, height and roof
South Australia runs two separate consents, and a project can need one, both or neither:
Planning consent is about whether the structure is allowed where you want it: its size, height, position on the block and effect on neighbours. Building rules consent is about whether it's built safely and to the National Construction Code.
As a general guide, a small, low, open pergola behind the front of the house and within the boundary setbacks is often exempt from planning consent. Add a solid roof, more height, or attach it to the house and you're far more likely to need approval. Building rules consent can apply even when planning consent doesn't.
Those thresholds are indicative, not universal. They vary between councils and under the Planning and Design Code. So the only safe answer for your block comes from your council, the PlanSA tools, or a builder who checks it for you. We do that on every job.
When you probably don't need planning consent
A structure is more likely to be exempt from planning consent when it's all of the following. Treat this as a guide, not a guarantee:
- Domestic, serving a single house rather than flats or a business
- Small in floor area
- Low to the ground, under the height your council sets
- Open, with no solid roof
- Behind the front building line, not forward toward the street
- Set back from boundaries and clear of easements and council, stormwater or sewer assets
Even then, building rules consent may still apply. Exempt from planning is not the same as exempt from everything.
What usually triggers approval
- A solid roof, which generally turns a pergola into a verandah in planning terms
- A raised deck, or any structure above the exempt height
- Attaching the structure to the house
- Building over or near an easement or an authority's asset
- Heritage listings, character overlays, or being forward of the building line
If any of these apply, you'll likely need consent. That's not a problem, it just means we factor the application into the plan and timeline up front.
We check it before a sod is turned
Working out approvals is one of the things people dread about a build. We take it on. At the quote visit we assess what your structure needs against your council's rules, flag any consent before you commit, and build to the requirements so there are no surprises later.
You can also check your own position with the official tools at code.plan.sa.gov.au and your local council's planning department. For builds across Adelaide's south and the Fleurieu, that means councils like Onkaparinga, Mitcham, the Adelaide Hills, Holdfast Bay, Victor Harbor, Alexandrina and Mount Barker.
Approvals, answered plainly
Do I need council approval for a deck or pergola in SA?
Sometimes. SA uses two consents: planning and building rules. A small, low, unroofed structure behind the building line is often exempt from planning consent, but building rules consent can still apply. Thresholds vary by council, so check your council and PlanSA, or let us confirm it as part of the quote.
What's the difference between planning and building consent?
Planning consent is about whether the structure is allowed where you want it. Building rules consent is about whether it's built safely to the National Construction Code. A job can need one, both or neither.
Does a roofed pergola or verandah need approval?
Usually yes. A solid roof generally makes a pergola a verandah in planning terms, which almost always needs approval. Open pergolas within the exempt size and height are more likely to avoid planning consent.
What if I build without approval?
It can mean enforcement, fines, and trouble when you sell, since unapproved structures show up in property searches. Confirming up front is far cheaper. We check the approval position before any work starts.
We'll sort the approvals
Tell us about your deck or pergola and we'll be in touch within 24 hours. We'll assess what your council requires as part of the quote, so you don't have to.
