If you’re planning to subdivide land in Sydney or anywhere across NSW, a Preliminary Plan of Subdivision is the document that can make or break your Approval. This guide explains what it is, why it’s required, how the process works, and what causes applications to fail.
What Is a Preliminary Plan of Subdivision?
A Preliminary Plan of Subdivision — also called a draft plan of subdivision — is a plan that maps out how an existing lot of land will be divided into separate lots. It shows the proposed boundaries, dimensions, and layout of every new parcel, along with any easements that will be necessary.
The plan is usually prepared by a Registered Surveyor and forms a mandatory part of a Development Application (DA) or CDC (Complying Development Certificate) for subdivision consent in NSW. Without it, council or a private certifier cannot assess whether the proposed lot layout is feasible, legal, or compliant.
Why Is It Required in NSW?
Under the Conveyancing Act 1919 and the Environmental Planning and Assessment Act 1979, any subdivision of land in NSW must have a signed Subdivision Certificate or Letter Confirming Exemption, before it can be registered with NSW Land Registry Services (LRS). Council and Certifiers need to verify that:
- Each proposed lot meets the minimum lot size and frontage requirements under the relevant Local Environmental Plan (LEP)
- The layout complies with development control plan (DCP) provisions on setbacks, access, and services
- Easements and rights of way are correctly identified and shown
- The proposal doesn’t adversely affect adjoining properties
What Does a Preliminary Plan Include?
A properly prepared plan of subdivision will typically show:
- Proposed lot boundaries — defined dimensions, bearings, and areas for each new lot
- Existing structures — existing or proposed dwelling and garage locations
- Easements and rights of way — drainage, services, access, and any encumbrances on the title or proposed to be created by the subdivision.
- Services infrastructure — stormwater, sewer, electricity, and water connection points
- Road access — driveway locations, kerb crossings, and any required road dedications
- North point, scale, and survey datum where relevant
- Compliance annotations — lot sizes checked against LEP minimums, setback notations if requried
The Sydney Subdivision Process: Step by Step
Step 1: Preliminary Plan of Subdivision
A site survey known as a “Detail and Boundary Identification Survey” is undertaken to survey the current state of the land and title. From this, a Registered Surveyor d prepares the plan showing the proposed lot layout. This is submitted as part of the DA or CDC application to council or a private certifier.
Step 2: Development Application Approval
Council or the certifier assesses the application against planning controls and issues conditions of consent. Common conditions include infrastructure contributions, drainage works, or utility connections that must be completed before the final plan is lodged.
Step 3: Final Plan of Subdivision
Once consent conditions are satisfied, the Registered Surveyor prepares the final plan, and endorsements and consents are obtained from council, certifiers, and any mortgagees or alike. The completed documents are lodged with NSW LRS. When registered, separate Certificates of Title are issued for each new lot. NSW Compliance Requirements
What your plan must demonstrate depends on your specific council and zoning. Key controls that a land subdivision plan in Sydney will typically need to satisfy include:
| Requirement | Governed by |
| Minimum lot size | Local Environmental Plan (LEP) |
| Minimum road frontage | LEP / DCP |
| Setback compliance for existing structures | DCP |
| Easement widths and service clearances | Sydney Water / Ausgrid standards |
| Stormwater drainage | Council engineering specs |
| Bushfire / flooding overlays | NSW Rural Fire Service / Department of Planning, Housing and Infrastructure |
Requirements vary significantly between councils, so always confirm which controls apply before the plan is drafted. You should also consider if your development may meet Complying Subdivision rules which can streamline your approval and reduce associated costs.
Costs, Fees, and Timeframes
Survey fees
The surveyor’s fee for preparing a Preliminary Plan depends on site complexity, lot count, and whether additional survey work is required first.Council and application fees
DA fees for subdivision in NSW are set as fixed per-lot fees under Schedule 4 of the Environmental Planning and Assessment Regulation 2021, not calculated on estimated development cost. This cost may change each year, so make sure to check with the NSW Department of Planning, Housing and Infrastructure for the latest fees.
Timeframes
Preliminary Plans can generally be prepared within 5–7 business days of site inspection. Council assessment typically takes 80–130+ days for a standard residential subdivision under the latest NSW Government benchmarks, though actual times vary significantly between councils. Final survey works are typically undertaken in preparation for the final subdivision plan towards the end of a development construction. Once the final plan is lodged with LRS, Registration is typically 4-6 weeks. Common Reasons Plans Get Rejected
Most DA refusals and amendment requests come down to a small number of recurring issues:
- Lot size below LEP minimum — the proposed lots don’t meet the minimum area for the zone, often because an older LEP minimum was assumed
- Inadequate road frontage — one proposed lot doesn’t have legal street access without creating an easement for access
- Structures straddling the boundary — a garage, shed, or swimming pool is positioned across the new boundary line and can’t remain there
- Unresolved easements — existing drainage or sewer easements run through the proposed lots in ways that restrict building envelopes below DCP requirements
- Incorrect or incomplete survey data — inaccurate dimensions, missing bearings, or outdated cadastral data that contradicts current title records
