What Has Changed
South Australia has implemented a series of planning reforms through its Planning and Design Code that make medium-density housing significantly more accessible. The changes have been phased in since 2023 and are now affecting property values and development potential across metropolitan Adelaide, including the northern suburbs.
The three most significant changes are:
Simplified medium-density approvals. Duplex, row dwelling, and small multi-unit projects now move through a more direct assessment pathway. What previously required extended negotiation with councils now falls within defined design standards that, if met, lead to faster decisions.
Faster digital assessment. The state's online planning portal has reduced approval timeframes and made the requirements more transparent. Developers and homeowners can check zone rules, overlay restrictions, and design standards before committing to a project.
Strategic up-zoning. Selected areas have been rezoned to allow higher building heights, greater site coverage, and more dwelling yield per lot. Properties in these zones have seen developer interest increase measurably.
What This Means for Northern Adelaide
If you own land in Salisbury Heights, Mawson Lakes, Hillbank, Salisbury Park, Craigmore, or Para Hills, this matters because these suburbs combine the features developers are looking for: larger land parcels, established infrastructure, schools nearby, and sustained buyer demand.
The areas affected by these reforms offer something inner-city suburbs cannot: block sizes that make duplex and small multi-unit development viable without land assembly. A 700 square metre corner block in Craigmore near a bus route is a different asset today than it was three years ago.
How Each Owner Type Is Affected
Homeowners may find their property attracting enquiries from developers and investors who previously focused on suburbs closer to the CBD. Corner blocks over 700 square metres in General Neighbourhood zones with access to transport and shops are the most sought after. Even if you have no intention of developing, this buyer competition supports your sale price.
Investors now have clearer pathways for dual-occupancy strategies. Faster approvals and defined design standards reduce the uncertainty that previously made these projects difficult to finance and plan.
Downsizers who own a larger block have options that did not exist in practical terms a few years ago: sell the whole block to a developer at a development premium, subdivide and sell the rear portion while retaining the front home, or engage a builder to construct a second dwelling and retain both. Each option has different tax and financial implications, which a conveyancer or financial adviser can help you work through.
What to Check on Your Property
Not every block in these suburbs benefits equally. Zone classification, block dimensions, frontage, access, and overlay restrictions all affect what is permissible. Two houses on the same street can have very different development potential depending on their exact specifications.
A proper assessment of your property's potential involves checking the Planning and Design Code for your zone, reviewing any heritage or environmental overlays, obtaining accurate measurements, and comparing against recent developer-purchased sites in the area.
I offer property evaluations for homeowners who want a clear picture of what their land is worth under current conditions, both for an owner-occupier sale and for a developer sale. The difference between those two numbers is often the most useful starting point for a decision.
