New Planning Code Promises Faster Approvals but Risks Leaving Affordable Housing Targets Unmet

The state government's new planning code, effective from July 1, aims to cut approval times for medium-density housing in Adelaide's designated 'activity centres' from an average of 18 months to just 12 weeks. The policy, outlined in the Planning, Development and Infrastructure (Streamlining) Amendment Act 2026, applies to areas like Bowden, Tonsley, and along the Gawler rail corridor. For residents in these suburbs, it means new townhouses and apartment blocks could appear faster, but local advocates warn the code does not mandate affordable housing contributions in these zones.

The change comes as South Australia grapples with a housing shortage projected to reach 22,000 dwellings by 2028, according to the state's Department of Human Services. The government says the policy is designed to 'increase housing supply and choice' by removing discretionary council review for projects that meet pre-approved design standards. However, the code's reliance on voluntary affordable housing agreements, rather than mandatory inclusionary zoning, has drawn criticism from community housing providers.

Who benefits under the new rules

Home builders and developers in the targeted growth corridors are the clearest winners. The code allows 'deemed-to-satisfy' approvals for projects of up to six storeys if they comply with built-form criteria such as setbacks, height and density. A report from the Urban Development Institute of Australia (SA) estimates this could cut holding costs by up to $40,000 per project, savings the institute says could be passed to buyers. For a family looking at a $650,000 townhouse in Bowden, that might trim the price by several thousand dollars, though no price guarantee is in the legislation.

But residents in established suburbs like Unley and Burnside see less benefit. The code excludes areas zoned as 'neighbourhood' or 'heritage', where separate assessment pathways still apply. Planning analyst Emily Carter of the University of Adelaide notes: 'If you live in a heritage zone, the new fast-track doesn't apply. Your neighbour's house extension may still take a year to assess, while a block of flats at the traffic lights gets approved in three months.'

Who misses out, and what's next

Affordable housing advocates say the policy's omission of mandatory targets leaves low- and moderate-income renters exposed. South Australia's housing trust reported last month that waiting list for public housing has grown to 18,500 households, up 12 per cent since 2024. Under the code, developers who include affordable units qualify for density bonuses of up to 20 per cent extra floor space, but no penalty exists for building all market-rate homes. The state government says it will review the code's impact on affordability by mid-2027, but critics argue the timeline is too late for families already priced out of rental markets like Salisbury and Elizabeth.

The policy also reserves a separate fast-track for AUKUS-related defence housing in suburbs adjacent to the Edinburgh defence precinct. Projects there can bypass local council input entirely under the Major Development Act 2025. The government says this is essential to house 4,000 additional defence workers by 2030. Local residents in Edinburgh North and Elizabeth have raised concerns about traffic and school capacity, but no independent assessment of infrastructure impacts has been published.

What happens next depends on the spring building season. The first batch of fast-tracked applications is expected by October. The government says it will publish quarterly data on approval times and housing starts. For Adelaide residents, the code promises speed, but whether it delivers homes anyone can afford is still an open question.
