Motorhome & Campervan VASS Certification in Victoria

Who can certify a campervan or motorhome conversion in Victoria? Commercial Vehicle Compliance (CVC) provides engineering assessment and VASS certification for applicable campervan and motorhome conversions in Victoria, including seating changes, structural modifications, body conversions and other vehicle changes that require engineering approval.

Approval pathway: Victorian campervan and motorhome conversions generally require assessment against the applicable vehicle standards and, where required, VASS certification. See the Transport Victoria campervan and motorhome conversion guidance and the NHVR VSG5 guidance.

Commercial Vehicle Compliance (CVC) provides engineering assessment and VASS certification for motorhome and campervan conversions in Victoria. We work with owners, converters, body builders and manufacturers to identify the applicable vehicle standards, modification codes and evidence requirements before and during the build.

Understand the requirements before you build or modify. Early engineering input can reduce failed inspections, rectification work and registration delays.

Electrical and gas installation evidence

For Victorian motorhome and campervan conversions, Transport Victoria requires mains-style electrical installations to comply with the applicable AS/NZS 3001 requirements. Mains-style electrical work must be carried out by a licensed electrician, and appropriate compliance evidence must be available to the VASS signatory before final approval. Gas-installation compliance evidence is also required where gas systems are fitted. See Transport Victoria VSI 5 for the current Victorian guidance.

🚐 Avoid Costly Mistakes Before You Start Your Build

Converting a vehicle into a motorhome or campervan involves more than just design and fit-out — it must comply with Australian regulations.

Without understanding the requirements, many builds result in:

Failed inspections
Costly rectification work
Registration delays

This guide provides general information and practical insight to help you understand what’s involved before and during your build.

⚖️ Motorhome & Campervan Compliance Requirements

Compliance depends on:

Vehicle category (typically NA/N vehicles)
GVM and load capacity
Seating configuration
Type of modifications carried out

Each vehicle must be assessed individually.

🚧 Common ADR Triggers in Conversions

The following are commonly affected depending on modifications:

ADR 3, 4, 5 → Seating and seatbelt changes
ADR 8 → Window and glazing changes
ADR 43 → Structural or dimensional changes

🔍 Examples of Modifications That Trigger Compliance Requirements

This is where many builds go wrong.

Adding or relocating seats
→ May require compliance with ADR 3, 4, 5
Installing or modifying windows
→ Must comply with ADR 8
Structural body modifications
→ May impact ADR 43 and require engineering approval
Adding amenities (beds, kitchens, storage)
→ Can affect weight distribution and load capacity

👉 The guide explains how these changes may affect compliance and what to consider.
