Council approval is one of the first hurdles in any Adelaide knockdown rebuild-and one of the most misunderstood. The process has changed significantly since the SA Planning Code came into effect, and requirements vary substantially between councils and zones.
Getting this right early saves time, money, and frustration.
Understanding What You Need
A knockdown rebuild typically requires two separate approvals: one for demolition and one for the new dwelling. Sometimes these can be combined; sometimes they can't.
Demolition approval is often exempt for standard residential demolition in general zones-you may only need to notify council and obtain a demolition permit from a licensed demolition contractor. However, in character areas, heritage zones, or where significant trees are involved, you'll need formal approval before demolishing.
Development Approval for the new dwelling is almost always required. This has two components: planning consent (does the design comply with planning rules?) and building rules consent (does it meet structural, fire, and energy requirements?). Both must be obtained before construction can legally begin.
Realistic Timeframes in Adelaide
Standard Residential Zones: 6-12 weeks
If your design complies with the Planning Code's deemed-to-satisfy criteria and you're in a standard residential zone (most of Adelaide's newer suburbs), approval is relatively straightforward. Expect 6-8 weeks for planning consent and building rules can often run concurrently.
Character Areas: 12-16+ weeks
In suburbs like Unley, Burnside, Norwood, and parts of Prospect, character overlay policies apply. Your design may need to respect streetscape, use certain materials, or maintain specific setbacks. Public notification is often required, adding 2-4 weeks minimum. Council planners may request design modifications.
Complex Applications: 4-6+ months
If your design significantly departs from the Planning Code (height, site coverage, setbacks), or if your property has heritage listing, significant trees, or flood overlays, the process becomes more complex. Assessment panels may be involved. We've seen applications take 6+ months in difficult cases.
How Different Adelaide Councils Vary
While all Adelaide councils operate under the same SA Planning Code, interpretation and processing times vary. Some councils are more design-focused; others prioritise compliance efficiency.
Burnside, Unley, and Norwood Payneham & St Peters have strong character protection policies. Expect more scrutiny of external design, materials, and streetscape impact. Early engagement with planners is worthwhile in these areas.
Tea Tree Gully, Salisbury, and Playford are generally more straightforward for complying designs. Newer suburbs without character overlays process faster.
Adelaide Hills Council adds complexity with bushfire overlays. BAL (Bushfire Attack Level) assessments and compliant designs are mandatory, which affects both approval timelines and construction methods.
Marion and Onkaparinga process good volumes of knockdown rebuilds, particularly in the southern suburbs. Generally efficient for complying applications.
Tips for Smoother Approval
Check zone requirements early. Before finalising designs, understand what's actually permitted on your property. The SA Planning Portal (PlanSA) lets you check zones and overlays.
Design to comply where possible. Deemed-to-satisfy designs (those meeting all Planning Code criteria) get faster approval with less scrutiny. If you're close to a limit, it may be worth adjusting the design slightly to avoid the 'Performance Assessed' pathway.
Engage council early in character areas. An informal pre-lodgement discussion with council planners can identify issues before you've finalised designs and paid application fees. This is particularly valuable in character zones.
Use experienced drafters or designers. Applications prepared by people who know Adelaide council expectations tend to process faster with fewer requests for additional information.
Keep neighbours informed. While not always required, proactively talking to neighbours about your plans can reduce objections and complaints that slow the process.

Common Questions
In most cases, yes. While demolition itself may be exempt in some zones, the new dwelling almost always requires Development Approval (DA). In character or heritage areas, you'll also need consent for the demolition. We help you understand exactly what approvals your specific property requires.
