Is My QLD Development a Code or Impact Assessment?
If you’ve begun delving into a planning scheme or information on your Council’s website, you may have already heard the terms Code Assessment and Impact Assessment. Now to figure out which one applies to your development! The heart of the matter is that Queensland’s planning system is designed to balance development needs with community and environmental needs. Let’s break it down so it’s digestible.
Code & Impact Assessment Definitions - Planning Act vs Plain Speak
The Planning Act 2016 (the Act) works in conjunction with local Council planning schemes to create the framework for development assessments. According to the Act (Section 45), the definitions of Code and Impact Assessment are:
- A code assessment is an assessment that must be carried out only -
- Against the assessment benchmarks in a categorising instrument for the development; and
- Having regard to any matters prescribed by regulation for this paragraph.
- An impact assessment is an assessment that -
- Must be carried out -
- Against the assessment benchmarks in a categorising instrument for the development; and
- Having regard to any matters prescribed by regulation for this subparagraph; and
- May be carried out against, or having regard to, any other relevant matter, other than a person's personal circumstances, financial or otherwise.
That’s all a rather round-about way of saying that Code Assessments suit the planning scheme’s regulations. Impact Assessments need a little bit more examining because some aspects of the development may have an adverse impact on surrounding community.
It’s important to note that, generally speaking, the majority of impact assessments do get accepted, however there’s extra steps involved in the process and usually extra conditions imposed on the approval of the development to take into consideration.

Key Differences - Code vs Impact Assessment
Public Notification is one key difference between the two types of assessment. This means the requirement to notify the public about your development through signage (have you seen those white signs at developments with key information on them?), in local newspapers, and direct to owners of adjoining lots.
- Code Assessment – not required
- Impact Assessment – required
There is a specific point toward the end of the Impact Assessment timeline when this must be carried out, and usually over a period of 15 business days.
Assessment Benchmarks and Relevant Matters are another key difference:
- Code Assessment – limited to assessment against the applicable state codes (not on every occasion) and local planning scheme codes. The assessment must only consider matters within those regulations.
- Impact Assessment – this is more comprehensive, requiring assessment against the full planning scheme, not just the relevant codes. For the most part, means addressing your development against the Strategic Framework of your local planning scheme in your report to ‘pitch’ how your development is suited to the overall visions and expectations for the area. How can your development meet or exceed the needs?
Level of Discretion is the next key difference. This simply means, “How much can the assessment manager apply their discretion when making a decision?”. The answer to that is that in Code Assessment, discretion has a limited use, whereas in Impact Assessment the Assessment Manager has more ability to use their discretion when making a final decision. This means, for example, that they are able to ‘not approve’ an impact application that meets codes if they believe it does not fit the strategic intent.
Assessment Timeframes is probably the key difference that people want to know most of all. Understandably, they want things processed ASAP.
- Code Assessment is generally the faster application to process as it is very prescriptive. Decision Notices, if not delayed by Information Requests, are required within 35 Business Days of the application being confirmed as being properly made.
- Impact Assessment takes longer because of the volume considerations and information outside of the relevant codes, as well as the public notification period. Decision notices are typically required within 45 business days plus the notification period of 15 (sometimes 30) business days. Again, this is increased if there is an Information Request issued.

So How Do I Know? - Code vs Impact Assessment
The Planning Scheme of your local Council is where that answer is found. Here’s the inside scoop to get you going:
Step 1 – Find your property’s Zone Code in the Council’s mapping (usually online mapping is available), e.g. low density residential zone
Step 2 – Find the Use Definitions in the planning scheme (this step is not required for subdivisions – also known as Reconfigure a Lot)
Step 3 – Find the Tables of Assessment section of the planning scheme and:
- Choose either Material Change of Use (MCU) or Reconfigure a Lot (RAL) section
- Find your Zone Code within the MCU or RAL section (this is where the process ends for RAL)
- Find your Use Definition within that Zone and it will tell you not only what assessment level, but also what codes are relevant (except overlays).
The Assessment Level will either be Accepted Development (no application required), Code Assessment, Impact Assessment, or Prohibited Development (will not be considered).
