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.

Depends on your lot

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.

Wanneroo: assessed by City of Wanneroo under the Western Australia rules below.

Approval pathway: Unlike every other state, you apply directly to the Western Australian Planning Commission (WAPC), normally through the Planning Online portal using Form 1A for freehold or survey-strata subdivision. The WAPC refers the application to your local council and to servicing agencies (Water Corporation, Western Power, Main Roads and others) for comment, then makes the decision - it has 90 days to do so. Approval comes with conditions: you clear each condition with the relevant agency within the approval's currency period, a licensed surveyor prepares the deposited plan or survey-strata plan, Landgate certifies it, the WAPC endorses it and Landgate then registers the new titles. Your council still assesses development applications for what you build on the resulting lots, but it cannot approve the subdivision itself.

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

Overlays can change your eligibility

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.
