Subdivision rules in Wanneroo
Building a subdivision in Wanneroo? City of Wanneroo applies the Western Australia planning framework. Here's what that means locally — plus the overlays worth checking on your specific block.
The WA Planning Commission decides subdivision, not your council
Whether you can subdivide depends on the R-Code density coded to your lot in the local planning scheme and on the minimum and average site areas that code allows. The distinctive feature of Western Australia is who decides: subdivision approval is granted by the Western Australian Planning Commission, a state body, not by your local council.
Key rules at a glance
| Minimum lot size | Driven by the R-Code density coded to your lot in the local planning scheme - indicatively R20 allows an average 450 m² and minimum 350 m² per dwelling, R25 an average 350 m² and minimum 300 m², R30 an average 300 m² and minimum 260 m² (indicative, coded per property) |
| Approval needed | Subdivision approval from the WA Planning Commission (Form 1A), then clearance of all conditions before titles can issue |
| Assessed by | The Western Australian Planning Commission - your local council is only a referral agency for subdivision, not the decision maker |
| Frontage | Set by the R-Codes and the local planning scheme - commonly 10 m or more for a green title lot, with prescribed access leg widths for battle-axe lots (indicative) |
| Typical timeframe | The WAPC has 90 days for a small subdivision (120 days for more than 100 lots) to decide, and 3-5 months is typical including preparation; clearing conditions and reaching titles commonly takes 12-24 months in total (indicative) |
| Title created | Green (freehold) title on a deposited plan, or survey-strata / strata title where lots share common property |
| Final step | Clearance of all conditions, WAPC endorsement of the plan, then registration at Landgate |
| Site area by density code | Table D of R-Codes Volume 1 (as amended 10 April 2024) sets site area per dwelling by density code, as minimum / average m²: R2 5000 min only; R2.5 4000 min only; R5 2000 min only; R10 875 / 1000; R12.5 700 / 800; R15 580 / 666; R17.5 500 / 571; R20 350 / 450; R25 300 / 350; R30 260 / 300; R35 220 / 260; R40 180 / 220; R50 160 / 180; R60 120 / 150; R80 100 / 120. The minimum is the floor for any single lot; the average governs how many lots or dwellings the site yields. Table D also directs that the R80 site area requirements apply to all single houses and grouped dwellings located on lots coded R100, R160 and R-AC, where apartments are instead governed by R-Codes Volume 2. |
| WAPC lot area variation | Under R-Codes P1.1.2 the WAPC, in consultation with the local government, may approve a green title, survey-strata or strata lot up to 5 per cent below the Table D site area, where the variation protects an environmental or heritage feature, retains a significant streetscape element, gives lots frontage to more than one public street, overcomes an unusual limitation of the land, allows housing of the same type as land in the vicinity, or achieves a local planning objective. |
Heritage, flood and bushfire controls on your specific lot can remove the fast-track and require a full application — even when the general rules say you're fine.
How often this applies in Wanneroo
These are the overlays that can remove the fast-track, measured across every parcel in Wanneroo from the same data behind our zoning map. They describe the council, not your block, and they are counted separately — one parcel can carry more than one, so they cannot be added together.
| Overlay | Share of parcels | What that means here |
|---|---|---|
| Heritage | Not mapped | No heritage mapping is published for Wanneroo, so it cannot be ruled out here. That is not the same as the land being clear. |
| Flood | Not mapped | No flood mapping is published for Wanneroo, so it cannot be ruled out here. That is not the same as the land being clear. |
| Bushfire | 21.81% | 23,194 parcels flagged. The rest are mapped and sit outside it. |
The most common zone in Wanneroo is Residential, covering 66.1% of its 106,364 parcels. What you can build is decided by your own lot's zone, not the council's most common one.

Who approves subdivision in Western Australia?
The Western Australian Planning Commission (WAPC), not your local council.

Councils in WA still assess development applications for buildings, but they cannot approve a subdivision.
