How Long Does It Take to Get Building Plans Approved in Australia?

Time is money in the building industry. Whether you're a builder with crews waiting or a homeowner eager to start your renovation, knowing how long the approval process takes helps you plan effectively.

Here's a realistic guide to approval timelines across Australia, with a focus on Victoria and New South Wales.

Overview of Approval Timelines

Planning Permit (Victoria)

• Standard application: 8–12 weeks (statutory timeframe: 60 days)
• Complex application (multi-unit, heritage): 12–24 weeks
• With objections or VCAT appeal: 6–18 months

Building Permit (Victoria)

• Standard residential: 2–4 weeks
• Complex residential: 4–8 weeks

Development Application (New South Wales)

• Standard DA: 6–12 weeks (statutory timeframe: 40 days for residential)
• Complex DA: 12–26 weeks
• Complying Development Certificate (CDC): 2–4 weeks

Building Approval (Other States)

• Queensland: 4–8 weeks typical for standard residential
• South Australia: 4–12 weeks depending on assessment pathway
• Western Australia: 6–12 weeks for standard applications

Why Do Approvals Take So Long?

Council Workload

Many councils across Australia are dealing with high volumes of applications and limited staff. This is especially true in high-growth areas of Melbourne and Sydney.

Referrals

Applications often need to be referred to other departments or authorities, heritage advisors, traffic engineers, environmental officers. Each referral adds time.

Advertising and Objections

Planning permit applications in Victoria are often advertised to neighbours. If objections are received, the council must consider them, which adds weeks or months to the process.

Incomplete Applications

Applications submitted with missing information or non-compliant drawings are delayed while the council requests further information. This is one of the most common, and most avoidable, causes of delay.

How the Drafting Phase Affects Your Timeline

Before you can submit for approval, your drawings need to be prepared. Here's what a typical drafting timeline looks like:

• Site measure: 1–3 days. Where there is no reliable plan, that visit is site measurement and as-built drawings in Melbourne.
• Design development: 3–7 days (depending on complexity and client feedback)
• Drawing production: 5–10 business days
• Client review and revisions: 2–5 days

Total drafting time: 2–4 weeks for most residential projects

A full permit set is not the only drafting job. When the drawings already exist, a markup is quicker than starting again. Redline plans for liquor licences are a separate, shorter job: a licensed-area plan, not a building permit.

At Arya Designs, we prioritise fast turnaround without compromising quality. Most projects are quoted within 24 hours and completed within 5–10 business days.

How to Speed Up the Approval Process

1. Start with Accurate Drawings

The single most effective way to avoid delays is submitting accurate, compliant drawings the first time. Incomplete or non-compliant drawings almost always result in requests for further information (RFIs), adding weeks to your timeline.

2. Check Planning Requirements Before You Design

Understanding your local planning requirements before you start designing prevents costly redesigns. Check setbacks, height limits, site coverage, and any overlays that apply to your property.

3. Pre-Application Meeting

Some councils offer pre-application meetings where you can discuss your proposal with a planning officer before formally submitting. This can identify potential issues early.

4. Use a Private Building Surveyor

For building permits, private building surveyors are often faster than council surveyors. They operate on commercial timelines and can typically issue permits within 2–3 weeks.

5. Respond to RFIs Quickly

If council requests further information, respond quickly and thoroughly. Delayed responses push your application to the back of the queue.

6. Consider Complying Development (NSW)

In New South Wales, many residential projects qualify for a Complying Development Certificate (CDC), which can be assessed and issued in as little as 10 business days, much faster than a full DA.

What Can Cause Unexpected Delays?

• Neighbour objections, can add weeks to months, potentially leading to tribunal (VCAT in Victoria, Land and Environment Court in NSW)
• Heritage overlay, heritage applications often require additional reports and take longer to assess
• Environmental factors, vegetation removal, flood overlays, or bushfire requirements add complexity
• Amended plans, if you change your design after submission, the assessment clock often resets
• Council elections or restructuring, can temporarily slow processing times

Planning Your Project Timeline

Here's a realistic timeline for a typical residential extension in Victoria:

1. Drafting: 2–3 weeks
2. Planning permit application: 8–12 weeks
3. Building permit application: 2–4 weeks
4. Total before construction: 12–19 weeks (3–5 months)

Plan accordingly. If you need to start construction by a specific date, work backwards from that date and add buffer time.
