How to subdivide land in Adelaide.

Can I subdivide my block in Adelaide?

Possibly. It depends on what the Planning and Design Code allows for your site. Every property sits in a zone, and many zones set a minimum site area and minimum frontage for each new allotment. These local figures are called technical and numeric variations. If your block can be split into lots that meet them, division is worth investigating.

The numbers are only the start. Before committing, we check:

• Overlays such as historic or character areas, flooding, or regulated and significant trees, which can add assessment or limit what is possible.
• Frontage and access: whether each new lot can have its own driveway and crossover, or needs a shared driveway like our Glenunga project.
• Street infrastructure: Stobie poles, street trees, pits and kerbs in the way of new crossovers. On our Ingle Farm corner block, the plans had to work around a Stobie pole, a street pit and a street tree.
• Services: sewer, water, power and stormwater for each new lot.
• Easements and existing buildings that affect where new homes can go.

Torrens title or community title?

Most small Adelaide infill divisions create Torrens title allotments. Each owner holds their own land outright, with no shared property and no corporation fees. Community title suits sites where lots share common property, such as a driveway or visitor parking, managed by a community corporation. The right choice depends on the site layout, the zone and how the homes will be sold or held. It's worth deciding early, because it shapes the whole plan.

The land division process, step by step

1. Feasibility. Check the zone, overlays and minimum lot sizes, then test a layout and rough budget before spending on drawings.
2. Survey and proposal plan. A licensed surveyor surveys the site and prepares the proposed plan of division.
3. Design the homes. Most infill divisions are lodged together with the new dwellings, so site plans, floor plans, elevations and landscaping are drawn now.
4. Lodge through PlanSA. Applications are lodged online through the PlanSA portal and assessed by the relevant authority, with referrals where required.
5. Consent and conditions. Approval comes with conditions, typically SA Water connections and fees, plus council requirements such as crossovers and street trees.
6. Clearance and new titles. Once conditions are met, the final plan is lodged with the Lands Titles Office and new certificates of title are issued for each lot.

How long does land division take?

There is no fixed timeframe. It depends on the assessment pathway, whether the application goes to public notification, how many requests for information come back, and how quickly conditions are cleared. As a real example, our Davoren Park townhouses took 358 days from lodgement to full approval for four homes on one 784 m² site. Plan for months, not weeks, and allow for the approval phase in your holding costs.

What costs should I budget for?

Every site is different, so get quotes for your own block. The usual cost items are:

• Survey, the proposal plan and the final plan of division
• Design and planning drawings, plus engineering where needed
• Lodgement and assessment fees
• SA Water connection and augmentation charges
• Council requirements such as new crossovers, and street tree removal or replacement
• Demolition of existing structures, if any
• Conveyancing and legal fees
• Holding costs: interest, rates and insurance while approvals run
