Home extensions and renovations in Gold Coast — do you need approval?
City of Gold Coast's planning scheme — the Gold Coast City Plan (City Plan) — Part 5 Tables of assessment (v14, 2026-09-29) — decides whether an extension needs a development application, and the answer depends on the zone your property is in. Below is what its table of assessment says for each zone; or check your own address.
In a low density residential zone
No planning approval needed. Extending or renovating your house is accepted development under the planning scheme unless an overlay applies, but you still need a building approval.

Overlays that change the answer
- Dwelling house overlay. On land mapped on the Dwelling house overlay, a dwelling house (including a secondary dwelling) involving building work that includes a partial third storey (up to 9m) becomes code assessable; if it exceeds the mapped height or 9m / a partial third storey it becomes impact assessable (needs a development application). (Table 5.10.5 Dwelling house overlay)
- Flood overlay. In a 'Flood assessment required' area, development otherwise accepted becomes accepted subject to requirements (must meet the Flood overlay code); operational earthworks over 5m³ not tied to building work/MCU become code assessable. (Table 5.10.11 Flood overlay)
- Heritage overlay. In a 'Local heritage place', building work that does not demolish/relocate/remove becomes code assessable; building work that partly or fully demolishes/relocates/removes becomes impact assessable (a development application that may be publicly notified). Essential repair/maintenance under the Queensland Heritage Act is unchanged. Operational work becomes code assessable. In a 'Place in proximity to a local heritage place', new buildings/extensions can become code assessable. (Table 5.10.12 Heritage overlay)
- The Spit Master Plan height sensitive area - building height overlay. On a site within 'The Spit Master Plan height sensitive area', building work (or MCU involving building work) that exceeds the mapped height becomes impact assessable, except Sea World theme park rides and associated structures. (Table 5.10.23 The Spit Master Plan height sensitive area - building height overlay)
- Road widening overlay. On a lot affected by a 'Road widening requirement area', the category of development is not changed but the Road widening overlay code is an added assessment benchmark. (Table 5.10.20 Road widening overlay)
Worth knowing in Gold Coast
Precinct variations within zones can change answers materially: e.g. the Low density residential and Township 'Large lot' precincts allow no additional subdivision lots and have their own MCU tables; the Calypso Bay precinct lowers the Low density residential minimum to 400m²; Future industry precincts require 20ha; the Rural 'Rural landscape and environment' and Rural residential 'landscape and environment' precincts prohibit/limit new lots. Subdivision thresholds use the Residential density overlay (RD1–RD8) in medium/high density residential zones and the Minimum lot size overlay map elsewhere — always check the overlay maps for the specific lot. Schedule 12 'one into two' subdivision does NOT apply anywhere in Gold Coast because the whole city is affected by overlays, so all genuine subdivision is at least code assessable. For all building work (sheds, pools, fences, extensions, demolition) a separate building approval under the Building Act 1975 is also required even where no planning (City Plan) approval is needed. State Vegetation Management Act rules for clearing are separate from the City Plan Vegetation management code. The Special purpose zone is largely regulated by other legislation (see Part 10); the Special development area precinct makes any use impact assessable. Note multiple overlays can apply to one site and the most onerous category prevails.
