Code and impact assessment

If you want to do any development on your property, you may need to submit an application to us or a building certifier for assessment.

Development is when you:

  • carry out building work
  • undertake plumbing or drainage work
  • do operational works, such as earthworks, roadworks, landscaping, sewerage and stormwater drainage
  • reconfigure or subdivide a lot
  • make a material change to how you use a property.

The Planning Act 2016 (Qld) governs all development in Queensland. When we receive an application, we assess it against the Toowoomba Regional Planning Scheme.

It’s important to understand the development application process. This will help you see the bigger picture under which we assess your application.

The Department of State Development, Infrastructure and Planning has more information about development assessment.

Assessment categories

Development proposals can be subject to different assessment categories:

  • code assessment
  • impact assessment.

Each category specifies the process your proposal must go through.

Some developments, such as low-risk code-assessable development applications that meet the planning scheme requirements, may be suitable for FastTrack Assessment.

Read Part 5 of the Planning Scheme to understand:

  • which assessment category your application comes under
  • the assessment benchmarks you must regard in your application.

Code assessment

Code assessment means we can only assess your development proposal against particular ‘assessment benchmarks’. It’s also known as ‘bounded assessment’.

We assess code-assessment proposals against:

In our region, most assessment benchmarks will be the codes in the planning scheme.

Assessment process

The Development Assessment Rules outline the assessment process for code-assessable development applications. The process can depend on the specific application but may include these standard steps:

  • submitting a development application to us
  • possible referral of parts of the application to a state agency
  • an opportunity for us to ask for more information about the application
  • our decision to approve (full or in part) with conditions or refuse a development.

You are not required to advertise code-assessable development applications for public comment.

Our determination

Council officers assess and decide code-assessable applications.

Sometimes an application may be referred to a meeting of Council for a decision if it’s:

  • contentious
  • of interest to the councillors
  • substantially non-compliant with the relevant benchmarks.

Impact assessment

Impact assessment is a more comprehensive process than code assessment.

Applications are assessed against: 

They may also be assessed against any other relevant matter identified in the process, such as planning need.

Impact-assessable development applications must be publicly notified. Anyone can lodge submissions about the application during the public notification period.

We consider any 'properly made' submissions we receive during the notification period.

We cannot consider personal or financial situations of an applicant, developer or submitter during an assessment.

Assessment process 

The process is similar to code-assessable applications but includes a public notification period. It may include these standard steps:

  • submitting a development application to Council
  • possible referral of parts of the application to a state agency
  • an opportunity for us to ask for more information about the application
  • notifying the public through such things as the newspaper, at the premises or contacting adjoining landowners
  • our decision to approve (full or in part) with conditions or refuse a development.

Council determination

Council officers assess and decide code-assessable applications. Sometimes an application may be referred to a special meeting of Council for a decision if it's:

  • contentious
  • of interest to councillors
  • substantially non-compliant with the relevant benchmarks. 

Preliminary approvals and variation requests

Under Schedule 2 of the Planning Act, a variation approval is part of a preliminary approval for premises. It varies the effect of a local planning scheme on a property.  

Read more about applying for a preliminary approval including a variation request(PDF, 306KB) .

Development restrictions

There might be restrictions over your proposed development that may be identified in an overlay.

Search the planning maps to see what zones, overlays and plans apply to the proposed development area.

Infrastructure requirements

Most developments require the provision of infrastructure to service the development, such as:

  • roads
  • water supply
  • sewerage
  • stormwater.

As part of development approval, new developments need to pay a share of the cost of infrastructure. We apply infrastructure charges to do this.
