Renovation Permits Melbourne: Council Requirements by Project Type

The most important distinction is this: a building permit deals with how something is built, while a planning permit deals with whether a particular change is allowed on the land in the first place.

• Building permit: Commonly tied to structural work, regulated building changes, wet-area compliance and formal approval by a building surveyor.
• Planning permit: Commonly tied to overlays, neighbourhood character, setbacks, heritage constraints, site coverage and extension form.
• Trade compliance: Plumbing, electrical and gas work can require certificates even when a broader planning permit is not involved.

Some projects require one, some require both, and some need neither but still need licensed trade compliance. That is why the approval pathway should be scoped before demolition starts.

A cosmetic kitchen replacement often avoids formal permit complexity, but that only applies if the scope truly stays cosmetic.

• Usually permit-free: Replacing cabinetry, benchtops, splashbacks and appliances within the same basic room envelope.
• Usually needs licensed compliance: New gas appliances, altered water connections, electrical circuits and switchboard changes.
• Usually needs building approval: Removing walls, altering beams, changing openings or doing structural work to open the kitchen to living spaces.

The mistake many owners make is assuming an open-plan kitchen is still just a kitchen renovation. Once structure changes, the project shifts into a different approval category.

Bathrooms deserve extra caution because waterproofing, ventilation, drainage and wet-area electrical rules all create compliance requirements that do not apply in the same way to dry rooms.

• Waterproofing must align with the relevant wet-area standard.
• Licensed plumbing and electrical work should produce the correct certificates.
• Overlay-affected or heritage properties may create planning considerations even when the bathroom itself is internal.

Even when the approval pathway is straightforward, do not treat the bathroom as a simple cosmetic room. It is one of the most compliance-sensitive areas in the home.

As soon as a project grows the house footprint, alters setbacks, changes height or interacts with a planning overlay, approvals become more layered.

• Building permit: Expected for additions, significant structural works and most extension projects.
• Planning permit: Often triggered by overlays, siting issues, neighbourhood character controls or the scale of the addition.
• Heritage overlay: Can introduce review even where the project feels minor from the owner perspective.

A pre-application conversation or early planner review can save a large amount of time on extension work because it reveals the issues most likely to trigger redesign or delay.

Delays often come from assumptions, not from the permit system itself.

• Starting design work without checking overlay controls
• Assuming internal work can never trigger wider approval issues
• Treating structural openings as a cosmetic renovation change
• Ordering materials before drawings and scope are stable
• Leaving permit responsibility unclear between owner, builder and designer

One of the most useful early questions is simply: who is responsible for each approval step, and when will that happen? If nobody can answer clearly, the project is not ready to start.

Owner-builder pathways can look attractive on paper, but they shift risk and coordination burden back onto the homeowner. Insurance, record-keeping, sequencing and future resale disclosure all become more serious issues.

For experienced construction clients, that may be manageable. For most homeowners, the smarter move is using licensed professionals and confirming in writing who is handling planning advice, building permit documentation, engineering and trade compliance.
