Adelaide City Council Approves CBD Height Limit Changes, Affecting Central Housing Supply

Adelaide City Council passed amendments to the Planning and Design Code on 7 July that lift maximum building heights from eight to twelve storeys in designated central business district precincts. The changes apply to land parcels between King William Street and Frome Road, directly altering approval pathways for new apartment projects. Developers can now submit applications without seeking separate height variations for those sites.

Why the vote occurred in July 2026

State government housing supply targets released in the 2025-26 budget papers set a requirement for 15,000 additional dwellings in greater Adelaide by 2030. City council records show the amendments respond to that target by updating local zoning maps to match the updated code. The vote followed public consultation that closed on 15 June and received 87 submissions from residents and property owners.

Residents in the affected blocks will see more construction activity along Grenfell Street and Pirie Street over the next three years. New projects are projected to add 420 apartments, according to the council's planning assessment report. Households seeking rental accommodation in the central area gain access to units within 400 metres of the Adelaide Railway Station, while existing commercial tenants on the ground floors of redeveloped sites face lease renewal negotiations once construction begins.

Budget figures and next steps

The council's 2026-27 operational budget allocates $2.4 million for additional traffic modelling and heritage impact studies tied to the height changes. Local rates notices for properties within the rezoned areas will incorporate updated valuation data from 1 January 2027. Applications lodged under the new rules are expected to reach the council's development assessment panel by October 2026, with the first determinations scheduled for early 2027.
