What Does a Subdivision Permit Require?

What Does a Subdivision Permit Require?

A subdivision permit allows a property to be legally divided into separate lots. While approval is a major milestone, it is not the end of the process. The owner must still meet planning, engineering, drainage, infrastructure and legal requirements before the new titles can be created.

The mixed-use project comprising a childcare centre, retail premises and residential development—each on its own proposed lot—was approved by Council. We then applied for a subdivision permit to create the separate lots. This is what the permit conditions say in simple terms.

This article is an easy-to-understand summary of a typical subdivision permit. Every project is different, so the exact requirements, timing and costs will depend on the wording of the individual permit, approved plans and authority advice.

1. The Approved Plan Must Be Followed

The subdivision must be completed in accordance with the plans and documents approved by Council.

Before the plan of subdivision can be certified, updated plans must be submitted and endorsed. These plans may need to show:

• Final lot boundaries, dimensions and lot numbers.

• Easements for drainage, electricity, telecommunications and other services.

• Access arrangements and any required public access easement.

• Common property areas, shared driveways and service areas.

• Any requirements arising from the approved development plans.

• Requirements from the stormwater strategy and engineering plans.

Roads or land that must be transferred to the relevant authority.

Once endorsed, the layout cannot be changed without Council’s written approval.

2. Supporting Plans Must Be Approved

Before subdivision certification, several project documents may need to be finalised and endorsed. These can include:

• A geotechnical report.

• A staging plan.

• A construction noise and vibration management plan.

• A functional layout plan.

• A stormwater management strategy.

• A waste management plan.

• A car parking management plan.

• A signage and line-marking plan.

These documents help demonstrate that the proposed subdivision and development can operate safely and properly.

3. Drainage Must Be Resolved

Stormwater is often one of the most important parts of a subdivision.

A stormwater management strategy must be approved before the final subdivision plan can proceed. The strategy needs to show how stormwater will be collected, treated and discharged from the site without causing flooding or affecting nearby land.

The permit also requires:

• A legal point of discharge for stormwater.

• Approval for any connection to public drainage infrastructure or waterways.

• Drainage works that meet Council and the relevant water authority’s requirements.

• New lots to achieve required flood protection or freeboard levels.

• No polluted or sediment-laden runoff entering public drainage systems or waterways.

• Any temporary drainage works to be properly designed and constructed.

In simple terms, the project must prove that stormwater can leave the site legally, safely and without creating downstream problems.

4. Services Must Be Provided

Each new lot must have access to essential services.

The owner needs to make arrangements with the relevant service authorities for:

Water supply.

Sewerage.

Electricity.

Drainage.

Gas, where available or required.

Telecommunications.

Fibre-ready telecommunications infrastructure.

Any existing or new service easements must be identified on the plan of subdivision. If private electricity lines cross a new lot boundary, they may need to be relocated or replaced with underground services.

Before the subdivision is completed, the owner may need written confirmation that each lot is connected—or ready to connect—to the required services.

5. Civil Works Must Be Completed

Before a Statement of Compliance is issued, the civil works shown on the approved engineering plans generally need to be constructed.

Depending on the project, these works may include:

Vehicle accessways and shared driveways.

Roads, footpaths, kerbs and channels.

Drainage pipes, pits and water-sensitive urban design measures.

Street lighting, signs and line marking.

Shared service areas.

Works outside the property boundary.

Common property and public infrastructure.

Council may also require detailed “as-constructed” plans after the works are complete. These plans record what was actually built, rather than only what was originally designed.

The information may need to be submitted in CAD, PDF and GIS formats so Council can maintain accurate records of public assets.

6. Contributions and Legal Agreements May Apply

Before the subdivision can be finalised, the owner may need to pay development and open-space contributions under the relevant planning scheme and development contributions plan.

The permit may also require a legal agreement to be registered on title if the subdivision is completed before all approved buildings and works are finished.

This agreement can ensure that:

Future development of each lot remains consistent with the approved development permit.

Access is available for drainage construction and maintenance where needed.

The owner pays the costs of preparing and registering the agreement.

This is particularly important for mixed-use projects where separate lots are being created before all construction has been completed.

7. Certification Is Not the Final Step

The subdivision process usually has two key approval stages after the planning permit.

Stage

Plan certification: Council and referral authorities approve the final plan of subdivision, including boundaries, lot numbers, easements, access and relevant authority requirements.

Statement of Compliance: Confirms that the permit conditions, infrastructure works, contributions and authority requirements have been satisfied. It is generally required before titles can be issued.

Before receiving a Statement of Compliance, the project may need to show that:

All required plans are endorsed.

Drainage and freeboard requirements are met.

Civil works and common property are complete.

Water, sewerage, power and telecommunications arrangements are in place.

Required contributions have been paid.

As-constructed drawings and asset information have been submitted.

Conditions from the related development permit have been satisfied.

8. Time Limits Apply

A subdivision permit does not last indefinitely.

The permit requires the plan of subdivision to be certified within the stated timeframe, commonly two years from the permit issue date. The development or each stage must then generally be completed within the stated period after certification, commonly five years.

If more time is needed, an extension-of-time request should be lodged with Council before the permit expires, or within the permitted period after expiry.

Key Takeaway

A subdivision permit is more than approval to create new lot boundaries. It is a detailed compliance process that coordinates the approved development, civil design, drainage, service connections, easements, contributions and legal documentation.

For a mixed-use project, early coordination between the town planner, land surveyor, civil engineer, architect, building consultant, project manager and service authorities is essential. A practical permit-condition checklist can help track responsibilities, required documents, authority approvals and timing so certification and Statement of Compliance are not delayed.
