Decking Across Metro Adelaide

All work in the CBD and North Adelaide Heritage Conservation Zone requires development approval regardless of deck height.

Heritage overlays in Hazelwood Park, Beulah Park and parts of Burnside trigger development approval for a deck.

Federation and Edwardian streetscape overlays in St Peters, Norwood and Kent Town can affect deck approval and design.

Hills-face zone setback requirements apply, and bushfire zones require AS 3959 compliant materials.

Coastal exposure zones require corrosion-resistant fixings - 316 stainless or class 4 hot-dip galvanised.

Bushfire Attack Level zones up to Flame Zone apply, and AS 3959 material restrictions follow the BAL rating.

Storm-surge zones in coastal pockets mean raised deck heights are common, and coastal salt corrosion applies.

Coastal corrosion and heritage overlays both apply across the beachside suburbs.

Pool zone classification under the SA pool-fencing regulations applies to any deck within 1.2m of a pool.

Reactive clay soil zone - footing depth is typically 1.2 to 1.5 metres to reach non-reactive strata.

A hills-face escarpment overlay applies in the foothill suburbs of the council area.

Reactive black-clay soil zone - footing detail must address soil heave and shrinkage.

Character and heritage overlays across Unley, Hyde Park and Malvern, on tight inner-south allotments.

Airport-corridor flat suburbs on mixed clay soils, with the coast close at the western edge.

Coastal corrosion at Semaphore and Largs, plus the historic Port Adelaide heritage zone.

Dense Federation and villa streetscapes with character overlays, where overlay-driven approval is common.
