An independent walk-through of PlanSA - the statewide South Australian planning portal. Understand development approval vs building consent, which overlays affect your block, typical timelines and fees, and how a knockdown rebuild in a Character Overlay is different from a greenfield build. Complements our CBS licensing and HBCF explainers.
Quick answer
PlanSA is the online portal for lodging development applications in South Australia. Every new home, knockdown rebuild, extension and major renovation above exempt-development thresholds needs approval. Standard timeline is 4-8 weeks; overlay-heavy blocks can take 8-16 weeks. Your builder typically handles lodgement.
Before 2020, each SA council ran its own planning system with different rules, forms and codes. The 2020 reforms consolidated everything into one statewide portal (PlanSA) governed by one Planning and Design Code. The result: faster approvals, clearer rules, and consistent overlays across every council. Your builder now lodges once at plan.sa.gov.au regardless of whether you're in Onkaparinga, Charles Sturt, or the Adelaide Hills.
These are separate approvals often confused. Development approval = permission to develop the land (does this design comply with the Planning and Design Code for this zone?). Building consent = permission to construct the specific building (does the design comply with the Building Code, structural engineering, energy and safety?). You need BOTH for a new home. Most builders lodge them together via a "single-stage" application through PlanSA.
Overlays are location-specific rules that override the zone default. On a standard suburban block with no overlays, PlanSA approval is straightforward and 4-6 weeks. On a Character Overlay block in Norwood or Prospect, expect design mods to match streetscape character + 8-12 weeks approval. On a Hills Face Overlay block, expect bushfire mitigation + landscape restrictions + 10-16 weeks. On a Heritage Overlay block, expect specialist heritage advice + demolition scrutiny + 12-20 weeks. Always check overlays via the PlanSA property lookup BEFORE signing a HIA fixed-price contract with a builder.

Go to plan.sa.gov.au, search your property address, and download the Property Report. It shows every overlay, zone, code assessment path and applicable regulation for your specific block. Do this BEFORE you tender to builders - it changes the design brief and quotable price significantly.
Volume builders (Metricon, Simonds, Fairmont, ABC Homes) always lodge for you as part of their fixed-price contract. Project + custom builders (Rossdale, Format, Oakford, Regent) usually lodge or work with a specialist planner. You can DIY-lodge on PlanSA but it takes deep knowledge of the Planning and Design Code to write a compliant proposal - the fees for professional lodgement are trivial compared to the cost of refusal or missed conditions.
PlanSA is the South Australian government's statewide planning and development portal at plan.sa.gov.au. It replaced the old council-by-council planning system in 2020 with a single online platform for lodging development applications, viewing the Planning and Design Code, checking overlays, and tracking approvals across all SA councils.
Yes for most new builds, knockdown rebuild projects, extensions and structural additions above the exempt-development thresholds. Small non-structural work (interior cosmetic renovations, standard fencing) is usually exempt. The Planning and Design Code on PlanSA sets the exact thresholds for your zone.
Standard residential development approval: 4-8 weeks. Complex overlays (heritage, character, flood, hills-face): 8-16 weeks. Anything requiring public notification: add 3-4 weeks. Your builder typically manages the lodgement; you sign as the property owner.
Fees vary by council and development value. Standard new-home application: $850-$2,400. Complex overlay-heavy applications: $2,400-$6,500+. Fees are set by regulation and paid to the relevant council (not to PlanSA itself, which is the portal).
Common Adelaide overlays: Character (Norwood, Prospect, Unley, Hyde Park, North Adelaide), Heritage, Hills Face (Adelaide Hills, Belair, Mitcham foothills), Flood, Historic Area, and Bushfire (Adelaide Hills, Southern Vales). Each triggers additional design requirements. Check your specific block via the PlanSA property lookup before signing a HIA fixed-price contract.
Development approval = permission to develop (planning). Building consent = permission to construct (compliance with the Building Code). Both are required for a new home in SA and are typically lodged sequentially or together via PlanSA. Your builder or a private certifier issues the building consent after development approval is granted.
Yes, PlanSA is designed for owner-lodgement, but most homeowners engage a private planner or their builder to lodge - the fees are low relative to the value of avoiding refusal or condition ambiguity. Volume builders always lodge for you; custom builders and architects usually manage it too.
You have appeal rights via the Environment, Resources and Development (ERD) Court. Most refusals are resolved by amending the design to comply with the Planning and Design Code. Working with a builder experienced in your specific overlay dramatically reduces refusal risk.
General information only. Planning rules, overlays, fees and processing times change over time. Always confirm current requirements with PlanSA and your council, and engage a qualified planner or building designer for your specific project.
