How to Check Overlays on Your Adelaide Block Using SAPPA
Every block in South Australia sits under a set of planning rules. Some are common. Some are specific to your street. Before you spend a cent on a design, you should know exactly what applies to your block. The state government publishes this information for free through SAPPA (South Australian Property and Planning Atlas).

What SAPPA is
SAPPA is the free public map maintained by PlanSA. It layers every zone, overlay, and planning control from the Planning and Design Code onto an interactive map of South Australia. You type in an address and it shows you what applies to that specific parcel of land.
Section 2
How to search your address
Go to sappa.plan.sa.gov.au. Enter your address in the search bar at the top. Click your parcel when it appears. The right-hand panel opens with a summary: zone, subzones, and every overlay that touches the block. Click any layer name to read the actual policy from the Planning and Design Code.
Section 3
What to look for first
Zone comes first (Residential, General Neighbourhood, Suburban Neighbourhood, Hills Neighbourhood, and so on). Then scan the overlay list. Common ones in Adelaide include Character Area, Historic Area, Regulated and Significant Tree, Hazards (Bushfire), Hazards (Flooding), Traffic Generating Development, and Airport Building Heights.
Section 4
Zone vs overlay: which wins
Where a zone rule and an overlay rule conflict, the overlay wins. Overlays are added because the parcel has a specific characteristic that needs extra care. Reading only the zone is a common and expensive mistake.
Section 5
What to do with what you find
Screenshot or download the SAPPA property report. Give it to any builder, designer, town planner, or private certifier you quote. It saves them time and it forces the conversation about design constraints early instead of after you have paid for drawings.
