What’s Changing (or Not) Under Clause 52.06-9

 

Recent updates to the Victorian Planning Provisions have triggered significant discussion across the planning and development industry, particularly around the growing use of “deemed to comply” standards in design and assessment.

The introduction of the Townhouse and Low-Rise Apartment Development amendments has been designed to simplify compliance and speed up approvals, but for traffic engineers and designers working within Clause 52.06-9 – Design Standards for Car Parking, the big question remains:

What does “deemed to comply” really mean for car park design and does it change how proposals are assessed?

 

When Compliance Doesn’t Always Mean Clarity

Clause 52.06-9 sets out detailed requirements for the design and layout of car parking spaces, including access aisles, gradients and manoeuvrability. In theory, if a design meets every requirement, it should be “deemed to comply.”

However, in practice, it’s rarely that straightforward. Even when layouts meet the geometric standards on paper, referral authorities and responsible councils often continue to request:

• Swept path diagrams
• Turning templates
• Operational analysis reports

This is particularly common in tight townhouse developments or basement car parks, where compliance doesn’t always guarantee practical functionality or safety.

So, if a layout fully complies with Clause 52.06-9, can it still be challenged on the basis of poor usability or vehicle accessibility? That’s the grey area.

The Grey Zone: Corrective Manoeuvres and Practical Functionality

One of the more nuanced issues in car park design is the acceptability of corrective manoeuvres, the small steering adjustments drivers make when entering or exiting a bay.

Design Standard 2 (Car Parking Spaces) provides geometric criteria, but it doesn’t specify whether every space should be accessible in a single movement. In basement layouts or compact townhouse sites, eliminating corrective movements can be impossible when considering structural columns, 90-degree turns or narrow access aisles.

That raises two important questions for traffic engineers and designers:

If a car park layout meets all geometric standards but still requires corrective movements, is it genuinely compliant?

 

Does “deemed to comply” extend to functional usability or is it limited to dimensional compliance?

 

These are critical distinctions that continue to challenge both design practitioners and approval authorities.

Why This Matters for Developers and Traffic Engineers

For developers, architects and traffic consultants, this difference between compliance and usability has real-world implications. Clients often seek clear, consistent answers to design questions like:

• How wide should the access aisle be behind garages?
• How many spaces can reasonably require corrective movements?
• If my design meets Clause 52.06-9 and AS2890.1:2004, do I still need swept path diagrams?

Without a unified interpretation across councils and referral bodies, these questions can lead to extended debates, project delays and additional costs, exactly what the “deemed to comply” framework aims to avoid.

As Victoria seeks to streamline the planning system and reduce red tape, consistency in applying car park design standards becomes increasingly important.

“Deemed to Comply” – The Idea vs. The Reality

The appeal of “deemed to comply” standards is clear: they promise predictability, efficiency, and reduced subjectivity. Yet for car park design under Clause 52.06-9, the reality is more complex.

Car parking design isn’t purely about meeting numbers or dimensions, it must also deliver safe, functional and user-friendly outcomes. Factors such as turning radii, access gradients and internal obstacles can make theoretical compliance insufficient in practice.

As a result, traffic engineering assessments remain essential. Swept path analysis, on-site observations, and case-by-case reviews continue to play a vital role in ensuring that car parks function as intended.

Until the planning framework explicitly defines what “deemed to comply” means in the context of car park usability, professional judgement will remain central to traffic and transport design outcomes.

What’s Next for Clause 52.06-9 and Car Parking Standards?

It remains to be seen whether the Townhouse and Low-Rise Apartment Code represents the beginning of a broader shift towards formal “deemed to comply” assessments in traffic engineering. For now, Clause 52.06-9 sits in a grey zone, objective in intent, but subjective in interpretation.

At Quantum Traffic, we believe that clarity around car park design standards would benefit all stakeholders. Clearer parameters would allow traffic engineers and urban designers to deliver layouts that balance compliance, practicality and efficient use of space without overdesigning or second-guessing approval outcomes.
