The Codes SEPP: How to Determine the Correct Planning Code for Your NSW Project

Choosing the right approval pathway is the most important decision in any property development journey.

In NSW the Complying Development Certificate (CDC) offers a streamlined alternative to the traditional council approval process, often saving months of assessment time. However, to leverage this fast-track system, you must first identify exacty which planning code applies to your specific land and project type.

At Town Planning Sydney, we specialise in providing expert CDC vs DA advice to ensure property owners and developers don’t waste time on the wrong application.

This guide breaks down the essential step of determining your applicable code within the State Environmental Planning Policy (Exempt and Complying Development Codes) 2008, commonly known as the Codes SEPP.

Clear Definitions of NSW Planning Terms

Understanding the legal framework is essential for any property owner or investor seeking planning approvals.

What is Complying Development?

Complying development is a combined planning and construction approval for straightforward development proposals. If your project meets all the predetermined development standards set by the state government, it can be approved by a private certifier or council without a full merit assessment.

What is a Section 10.7 Planning Certificate?

This is a legal document issued by your local council that confirms the planning rules and restrictions applicable to a specific parcel of land. Section 3 of this certificate is critical, as it explicitly states what category of complying development is possible on your land.

What is the Codes SEPP?

The Codes SEPP is the primary state-wide planning policy that contains the individual codes (rules) for various types of development, such as new houses, renovations, or commercial changes of use.

What is a Development Application (DA)?

A development application NSW is a formal request for consent from the local council when a project does not meet the strict requirements of a CDC. It involves a merit-based assessment against Local Environmental Plans (LEPs) and Development Control Plans (DCPs).

How to Determine Your Applicable Planning Code

To find your project's planning code in NSW, check Section 3 of your Section 10.7 Planning Certificate or use the Planning Portal Spatial Viewer to identify your land's zoning and specific designations, such as Greenfield or Inland areas.

Step-by-Step Selection Process

1. Check Your 10.7 Certificate: Always start by reviewing Section 3 of your planning certificate to see which codes are "switched on" for your land.

   
   

2. Verify Land Zoning: Use the Planning Portal Spatial Viewer to find your land zone (eg R2 Low Density Residential or RU1 Rural).

   
   

3. Identify Special Areas: Determine if your site is in a designated "Greenfield Housing Code" area or an "Inland NSW" local council area.

   
   

4. Match Project to Code: Use the land zoning and project type (eg new house, renovation, or multiple dwellings) to select the correct Part of the Codes SEPP.

   
   

5. Review Variations: Check Schedule 3 of the Codes SEPP and Part 3 of your local LEP for any specific variations or restrictions that apply to your council area.

   
   

Planning Codes for Residential and Multiple Dwellings

The Codes SEPP is broken down into specific Parts. Matching your project to the right Part is essential for compliance.

Single Dwellings and Minor Works

• Greenfield Housing Code (Part 3C): Applies to new land release areas designated to improve housing affordability. It generally applies to zones R1, R2, R3, R4, and RU5 in these designated areas.

  
  

• Inland Housing Code (Part 3D): This code applies specifically to numerous local council areas in regional and inland NSW, covering both rural and residential zones.

  
  

• General Housing Code (Part 3): The "standard" code for new or renovated detached single dwellings, garages, and carports in typical residential zones (R1-R4, RU5) that are not in heritage areas.

  
  

• Rural Housing Code (Part 3A): Specifically designed for larger rural lots in zones such as RU1, RU2, RU3, RU4, RU6, or R5.

  
  

• Housing Alterations Code (Part 4): Used for minor works like internal alterations or attic conversions. This code can sometimes be used in heritage conservation areas where other codes are restricted.

  
  

Multiple Dwellings

• Low Rise Housing Diversity Code (Part 3B): This covers "missing middle" housing, including dual occupancies (attached or detached), manor houses, and terraces in zones R1, R2, R3, or RU5.

  
  

Authority Signals: SEPPs, LEPs and DCPs

While the Codes SEPP provides state-wide rules, it does not exist in a vacuum. A town planner NSW must always look at the interplay between different frameworks.

• State Environmental Planning Policies (SEPPs): These take precedence over local rules for complying development.

  
  

• Local Environmental Plans (LEPs): Your local council's LEP may contain specific variations or additional restrictions for complying development within its area. Schedule 3 of the Codes SEPP lists many of these local variations.

  
  

• Development Control Plans (DCPs): While DCPs are primarily for DAs, they often inform the "character" requirements that might influence whether a project should remain a CDC or move to a DA for a better design outcome.

  
  

Town Planning Sydney Case Scenarios

Case Study 1: The New Build in a Bushland Suburb

A family purchased vacant land in a bushland suburb in metropolitan Sydney to build a two-storey house. They were initially unsure which code applied.

• The Strategy: They obtained a Section 10.7 planning certificate which confirmed their land was zoned RU1 Rural. Using the Planning Portal, they confirmed they were not in a Greenfield or Inland area.

• The Outcome: Based on the Rural zoning, they identified that the Rural Housing Code (Part 3A) was the correct path. This allowed them to review the specific development standards for rural builds, such as larger setbacks and bushfire requirements, before finalising their design.

  
  

Case Study 2: Dual Occupancy (Multiple Dwellings)

A developer wanted to build a detached dual occupancy on an R2 zoned lot in a well-established Sydney suburb.

• The Strategy: We reviewed the land zoning and the project intent. Because the project resulted in multiple dwellings on one lot, we bypassed the General Housing Code.

• The Outcome: The project fell under the Low Rise Housing Diversity Code (Part 3B). This code has very specific standards for site area and frontage that must be met to avoid a full council DA.

  
  

Misconceptions About Planning Codes in NSW

• "Any house can be a CDC": Incorrect. If your land is in a heritage area, a high-risk flood zone, or certain ecologically sensitive areas, the General Housing Code may be "switched off".

• "Codes are the same across NSW": While the SEPP is state-wide, there are significant variations for different council areas found in Schedule 3. For example, a setback requirement in one council area might be different in another.

• "I don't need to check my zoning if I'm just renovating": Even for internal works, some codes under Part 4 are only "switched on" for specific zonings.

  
  

FAQ Section

How do I find out what category of complying development is possible on my land?

You should refer to Section 3 of your Section 10.7 planning certificate, which is issued by your local council. This section explicitly lists which complying development codes apply to your property.

Do I need council approval for a new house in a rural zone?

If your project meets all the standards of the Rural Housing Code (Part 3A), you can obtain a CDC from a private certifier instead of going through the full council approval process.

What is the Inland Housing Code?

The Inland Housing Code (Part 3D) is a specific set of rules for single dwellings and ancillary structures that applies to designated regional and inland council areas across NSW, such as Albury, Bathurst, Dubbo, and Wagga Wagga.

Can I use the Greenfield Housing Code for any new land release?

No. Your land must be specifically designated as a Greenfield Housing Code area on official maps. You can check this using the Greenfield Housing Code Area layer in the Planning Portal Spatial Viewer.

Is a "Manor House" considered a single dwelling?

No. Manor houses and terraces fall under the Low Rise Housing Diversity Code (Part 3B) because they result in multiple dwellings on a single lot.

What happens if my project doesn't fit any of the Codes?

If your project cannot meet the strict development standards of any code in the Codes SEPP, you must lodge a development application NSW with your local council.

Determining the correct code is not just a checkbox exercise it is the foundation of your project's legal compliance. By correctly identifying whether your project falls under the General, Rural, Greenfield, or Inland codes, you can move forward with a Statement of Environmental Effects or a CDC application with total confidence.
