Building Approval Timelines: How Long Things Actually Take

If you're planning to build a new home or take on a renovation, one of the first questions you’ll likely ask is:

“How long will it take before construction can actually begin?”

It’s an important question, and the truth is that many homeowners are surprised to learn that the approval stage often takes longer than expected. Before any work starts onsite, your project must go through several steps to ensure it meets council regulations and Australian building standards.

At Prescom Constructions, we guide homeowners through this process from start to finish, so you always know what to expect. Below is a realistic breakdown of building approval timelines and some helpful tips to keep things moving.

Why Building Approvals Take Time

Building approvals exist for good reason. They help ensure your project is safe, compliant, and legally approved before construction begins.

The approval process confirms that your build:

• Meets structural and safety standards
  

• Follows national building codes
  

• Aligns with local council planning requirements
  

• Is properly documented for insurance and resale purposes
  

Although it can feel like a lot of paperwork, these steps protect your investment and help avoid costly issues later.

The Typical Building Approval Timeline in Australia

Approval timeframes vary depending on the type of build, your location, and how complex the design is. Here’s a general guide for homeowners.

1. Design and Drafting Stage (2–6 weeks)

This is where your project begins. During this stage, your builder and designer work on:

• Initial consultations
  

• Concept designs
  

• Floorplans and layout adjustments
  

• Budget alignment and planning
  

Homeowner Tip: Making key decisions early helps reduce delays later on.

2. Engineering and Reports (1–4 weeks)

Most projects require supporting documentation, such as:

• Soil testing
  

• Structural engineering
  

• Bushfire or flood assessments
  

• Stormwater and drainage reports
  

Some blocks require more reports than others, especially in higher-risk zones.

3. Planning Permits (If Required) (2–4+ months)

Not all builds require a planning permit, but many do—particularly if your project includes:

• Extensions or major renovations
  

• Multi-unit developments
  

• Heritage or special zoning areas
  

• Boundary variations
  

Planning permits are handled through your local council, and processing times can vary significantly depending on council workload and whether neighbour notifications are involved.

4. Building Permit Approval (2–6 weeks)

Once planning approval is complete (or if a planning permit isn't needed), the building permit is next.

This stage ensures the project meets building regulations, including:

• Structural compliance
  

• Energy efficiency standards
  

• Safety and construction requirements
  

In some cases, private certifiers can approve permits faster than councils.

5. Pre-Construction Readiness (1–3 weeks)

Before construction starts, final preparation takes place, including:

• Signed contracts
  

• Final material selections
  

• Confirmed project schedules
  

• Site preparation and access planning
  

Once everything is approved and documented, construction can officially begin.

So, How Long Does the Full Approval Process Take?

As a general guide:

• Small renovations may take around 4 to 8 weeks
  

• Standard new home builds often require 3 to 5 months
  

• Builds needing council planning approval can take 6 months or longer
  

Starting early is the best way to keep your timeline realistic and stress-free.

Common Causes of Approval Delays

Delays can happen for several reasons, including:

• Missing or incomplete documentation
  

• Changes to the design after submission
  

• Busy council approval periods
  

• Complex site conditions
  

• Neighbour objections during planning review
  

• Zoning or overlay restrictions
  

Even small changes can restart certain approval steps, so clear planning upfront is essential.

Homeowner Tips to Help Speed Up the Process

There are several ways homeowners can help keep approvals on track.

Make decisions early
Finalising layouts, finishes, and designs early prevents unnecessary revisions.

Understand your block limitations
Site slope, easements, and zoning overlays can affect approval requirements.

Avoid last-minute changes
Design changes after documents are submitted often add weeks to the process.

Work with an experienced builder
A builder familiar with council requirements can manage paperwork correctly and avoid common mistakes.

Stay informed with regular updates
Clear communication throughout the process helps you stay confident and prepared.
