Subdivision can look deceptively simple on paper: draw a new boundary, lodge an application and receive another title. In practice, there are several distinct stages between the first idea and having new titles ready to sell, finance or build on.
Understanding the process before you start makes it much easier to budget correctly, engage the right consultants and avoid delays.
Stage 1 - Feasibility
Before preparing a subdivision application, the property should be assessed to determine whether the proposal is both possible and worthwhile.
The early review typically considers:
- zoning, R-Code and any dual density coding;
- site area, dimensions and frontage;
- the position of the existing house and other structures;
- whether the property is better suited to side-by-side, battleaxe or another lot configuration;
- vehicle access and likely driveway requirements;
- sewer, water and power infrastructure;
- easements, restrictive covenants and other title interests;
- site levels, retaining and drainage;
- local planning policies and structure plans; and
- the likely cost and value of the development strategy.
This is the point where alternative options should be tested. A property that can technically create three lots may still produce a better result as two larger lots, particularly once access, construction and marketability are considered.
Stage 2 - Feature survey and subdivision design
A subdivision proposal needs to be based on accurate information about the land.
The WAPC's subdivision application guidance requires a subdivision plan and supporting information, and the proposal should be based on current survey information. A licensed surveyor will generally be involved in the project to establish boundaries, site features and ultimately the legal survey plan.
The subdivision layout is then developed around the R-Codes, WAPC policy, services, access and the intended future use of the lots.
Where an existing dwelling is being retained, this stage should also check how that dwelling will function against the proposed new boundaries.
Stage 3 - Lodge the Form 1A subdivision application
Freehold and survey-strata subdivision applications are lodged with the Western Australian Planning Commission, generally through Planning Online.
A typical application includes the proposed subdivision plan, current Certificate of Title, landowner consent and any supporting reports or justification required for the site.
The WAPC - not the local council - is the decision-maker for these subdivision applications.
Stage 4 - Referral to the council and servicing authorities
Once the application is accepted, it can be referred to the relevant local government and agencies such as Water Corporation, Western Power and Main Roads for advice.
The WA planning system describes a typical subdivision decision period of 90 days, with referral agencies generally providing advice within the first 42 days.
The local council may recommend conditions relating to matters such as access, drainage, crossovers, retained buildings, fencing or local infrastructure. Utility providers can recommend servicing conditions.
Those recommendations are considered by the WAPC when it determines the application.
Stage 5 - WAPC decision
The WAPC may approve the proposal, approve it subject to conditions, or refuse it.
Most residential subdivisions are approved subject to conditions. The decision letter is therefore one of the most important documents in the project because it establishes what must be completed before final endorsement.
For subdivisions creating five lots or fewer, the approval is generally valid for three years. For six lots or more, it is generally valid for four years.
There is also a statutory process for seeking reconsideration of a WAPC decision or conditions, and review rights may be available through the State Administrative Tribunal. These have strict timeframes, so professional advice should be obtained promptly if a decision is disputed.
Stage 6 - Work through the subdivision conditions
Conditional approval is not the same as having new titles.
The next stage is to satisfy each of the conditions in the WAPC approval. The conditions identify which authority is responsible for confirming compliance.
Depending on the property, works can include:
- water and sewer servicing;
- underground power;
- construction of a shared or battleaxe driveway;
- crossovers and drainage;
- demolition or removal of structures;
- retaining and earthworks;
- fencing;
- tree or landscaping requirements;
- modifications to an existing retained dwelling;
- easements, notifications or legal agreements; and
- other site-specific works required by the local government or service authority.
This is often the most management-intensive part of the project because several consultants, contractors and authorities may need to be coordinated in the correct sequence.
Stage 7 - Obtain condition clearances
When a condition has been satisfied, the relevant authority needs to provide written clearance or other evidence confirming compliance.
For example, the local government clears conditions allocated to it, while utility providers clear their own servicing conditions.
It is important to track every condition carefully. A single unresolved item can prevent the plan from moving to final endorsement.
Stage 8 - Final survey plan and WAPC endorsement
The licensed surveyor prepares and lodges the legal survey plan with Landgate.
At the final approval stage, a Form 1C request is made for WAPC endorsement. The WAPC requires the relevant plan and evidence that the conditions have been satisfied.
The current Form 1C guidance states that the WAPC is to try to deal with a complete endorsement request within 30 days.
This is the point at which the approved subdivision layout and the legal survey documentation come together.
Stage 9 - Landgate and new titles
Once the plan has reached the appropriate status and the required registration documents have been lodged, Landgate can progress the creation of the new Certificates of Title.
Landgate's Ready for Titles process allows plans and registration documentation to be progressed earlier and gives very high examination priority to plans that are ready for titles.
Your surveyor and settlement or conveyancing professional will generally coordinate the title-registration requirements at this stage.
When the new titles issue, the subdivision process is effectively complete and the individual lots can then be dealt with as separate properties, subject to any encumbrances or scheme arrangements.
How long does the subdivision process take?
There is no guaranteed end-to-end timeframe. A straightforward small residential subdivision is often allowed around six to 12 months in practical project planning, but it can be shorter or significantly longer.
The WAPC assessment period is only one component. The overall programme also depends on survey work, authority responses, contractors, servicing, clearances and Landgate processing.
A good project programme therefore identifies which conditions have long lead times and starts those tasks early.
Who do you normally need?
The consultant team varies from site to site, but a small Perth subdivision commonly involves a licensed land surveyor and may also require a building designer, town planner, civil engineer, structural engineer, geotechnical consultant, arborist, plumber, electrician, demolition contractor, earthworks contractor and settlement agent.
Not every project requires every consultant. The goal is to bring in the right people when their input is actually needed.
Why project coordination matters
Many subdivision delays are not caused by the planning approval itself. They happen between approval and titles because conditions are handled one at a time without an overall delivery plan.
For example, a retained-house modification may need to be designed and approved before a contractor can complete it; a driveway may need to wait for underground services; or a surveyor may need confirmation of completed works before finalising the plan.
Coordinating these dependencies early can reduce unnecessary rework and holding time.
How Shoreline Design can help
Shoreline Design can assist from the initial development and subdivision feasibility through design, approvals, consultant coordination and subdivision delivery.
For clients who want a more complete service, that means there can be one point of coordination across the design and subdivision process rather than the owner trying to manage each consultant and authority separately.
