What Adelaide's planners, developers and advocates really think about the city's housing crisis

Adelaide's housing emergency has sparked a rare moment of consensus among city planners, property developers and community advocates—though consensus about the problem, not the solution.

The South Australian Housing Authority released projections last month estimating the state needs 65,000 additional dwellings by 2036, with particular shortages in inner suburbs like Thebarton, Woodville and Prospect. Yet how to deliver them remains bitterly contested.

The state government's new zoning reforms, which allow multi-unit development on previously single-dwelling blocks across metropolitan Adelaide, have drawn praise from some quarters. The Urban Land Institute Australia highlighted the policy as a potential circuit-breaker, noting that cities like Melbourne and Sydney have used similar measures to moderately increase supply in inner-ring suburbs.

However, the Property Council of South Australia has expressed concern about the pace of infrastructure investment, particularly in schools, transport and utilities. "Rezoning is one tool," said a spokesperson at a recent planning forum at the Adelaide Convention Centre. "But without coordinated investment in roads, water systems and public transport, you're simply moving the problem around."

Local residents' associations have proven predictably fractious. The Inner West Community Alliance, which represents households across suburbs from Unley to Prospect, has warned that high-density development risks overwhelming neighbourhood character and parking capacity. Yet housing advocates argue such concerns often mask opposition to change that would benefit younger, lower-income Adelaideans priced out of suburbs their parents could afford.

University of South Australia urban planning researcher Dr. Emma Harrison told The Daily Adelaide that Adelaide faced a genuine fork in the road. "We can either intensify housing in established suburbs strategically, or we sprawl further out, which simply defers costs to infrastructure and transport," she said. "Most cities that have managed affordability well have chosen the former."

The state's Development Plan Amendment, enacted in May, permits up to four dwellings on plots currently zoned for single houses in designated areas. Early data from South Australia's planning database shows applications for dual and triple occupancy have increased 34 percent in Thebarton since the change took effect.

Yet the median Adelaide house price continues climbing. Property analysts attribute this partly to interstate migration and investment demand, factors regulatory reform alone cannot address.

City planners insist the reforms are working as intended—creating capacity, not guaranteeing immediate price relief. The real test, they say, will come in 18 to 24 months, when supply effects should filter into market data. Until then, Adelaide's housing debate will remain fractious.
