Deck & pergola rules in South Australia (2026)
Low decks can be exempt; roofed verandahs usually need approval
A deck in association with a house is exempt development if no part of its floor is more than 500 mm above natural ground. Higher decks, and roofed verandahs, generally need development approval, though many small verandahs and decks are assessed quickly on the deemed-to-satisfy pathway.
Key rules at a glance
| Deck exempt (planning) | No part of the floor more than 500 mm above natural ground |
| Pergola exempt | Open pergola without a fixed or hard roof (conditions apply) |
| Shade sail exempt | Up to 20 m² and no higher than 3 m |
| Verandah (roofed) | Generally needs development approval, often via deemed-to-satisfy |
| Building consent | Separate building-rules consent is usually still needed for raised decks and verandahs |
| Excluded areas | Exemptions do not apply in Flood zones, the Hills Face Zone or heritage areas |
Conditions & eligibility
- Deck floor no more than 500 mm above natural ground to be exempt
- A hard or fixed roof turns a pergola into a verandah, which needs approval
- Exemptions are removed in Flood zones, the Hills Face Zone and heritage areas or on State Heritage places
- A planning exemption does not remove the need for building-rules consent
- Check the property's zone and overlays on the SA Property and Planning Atlas
Heritage and flood controls on your specific lot can remove the fast-track and require a full application, even when the general rules say you're fine.
How approval works in South Australia
Under the Planning and Design Code, small works can be exempt (no approval), deemed-to-satisfy (fast, rule-based) or performance-assessed. Decks and verandahs that are not exempt usually go through the deemed-to-satisfy pathway. Building consent (building rules) is a separate approval that most raised decks and verandahs still need.
Some councils and zones (Hills Face, heritage) switch off the exemptions, so confirm on PlanSA before building.

Frequently asked questions
Do I need approval to build a deck in South Australia?
A deck with no part of its floor more than 500 mm above natural ground is exempt from planning approval. Higher decks generally need development approval, and most raised decks also need separate building-rules consent.
Do I need council approval for a verandah in Adelaide?
Usually yes. A roofed verandah generally needs development approval, though small ones are often assessed quickly under the deemed-to-satisfy rules of the Planning and Design Code.
Does a pergola need approval in SA?
An open pergola without a hard or fixed roof can be exempt development, subject to conditions. Adding a solid roof makes it a verandah, and sites in Flood, Hills Face or heritage areas lose the exemption.
