Do You Need a Building Permit for an Office Fitout in Victoria?

It is one of the most common questions we hear from tenants: "It's only partitions and a new kitchenette, surely we don't need a permit?" Sometimes that is right. More often, a small detail in the scope (a relocated exit sign, a new wall that cuts across a sprinkler head, a meeting room that changes the fire egress path) turns a "cosmetic" refresh into permit-controlled building work.

This guide explains how the rules actually work in Victoria, so you can plan your fitout with the right approvals from day one.

What does the law say?

Under the Building Act 1993 (Vic), building work must not be carried out unless a building permit for that work has been issued and is in force. The offence can apply to the person doing the work and to an owner who knowingly allows it.

The Building Regulations 2018 (Vic) then list work that is exempt from needing a permit in Schedule 3. For alterations, the exemption only applies if every condition is met. In plain terms, the alteration must:

• Not adversely affect the structural soundness of the building (no new load-bearing changes, no footing or underpinning work, no increase in floor area or height)
• Not adversely affect the safety of the public or occupants
• Not be work on, or work that affects, an essential safety measure
• Not be on a building on the Victorian Heritage Register

If your scope touches any of these, the exemption falls away and a relevant building surveyor needs to assess the work and issue a permit.

Which office fitout works usually need a building permit?

In our experience across commercial fitouts in Melbourne, these items almost always bring a project into the permit system:

• New or relocated walls that change exit paths, travel distances or corridor widths
• Any change to fire services: sprinkler heads, smoke detectors, fire hose reels, exit and emergency lighting, fire-rated walls or doors
• New or altered ceilings that interact with sprinkler coverage or fire separation
• Mezzanines, new floors, stairs or openings in slabs
• New accessible toilets or changes to the path of travel from the entrance
• A change of use, for example turning office space into a clinic, gym or training room
• Mechanical ventilation changes that affect smoke control

What might be exempt?

Genuinely cosmetic work often sits outside the permit system, provided it passes the tests above. Typical examples are painting, new carpet or floor finishes, joinery that is not fixed to the structure in a way that affects it, loose furniture, and like-for-like replacement of fittings. Even here, check with a building surveyor if you are unsure. It is quicker to get a written view at the start than to stop work mid-project.

Why essential safety measures matter so much

Essential safety measures are the systems that keep people safe in an emergency: fire detection and sprinklers, exit doors, exit signs, emergency lighting, fire-rated construction, paths of travel and more. They are regulated under Part 15 of the Building Regulations 2018, and the building owner must keep them maintained so they operate as intended.

A fitout that moves a wall 600 mm can shadow a sprinkler head or block the view of an exit sign. That is why the Schedule 3 exemption excludes work affecting an essential safety measure. It is also why your fitout builder should coordinate with the building's fire services contractor before any wall goes up.

Does a change of use trigger a permit?

Yes, in most cases. Under the Victorian building regulations a building must comply with the requirements for its new use before that use starts. If you are converting office space (usually Class 5 under the National Construction Code) to another use, such as a medical consulting suite, a training room with high occupant numbers or a childcare centre, expect a building permit and, at the end, a new or amended occupancy permit.

What about accessibility?

Where new building work needs approval, the Disability (Access to Premises — Buildings) Standards 2010 can apply not just to the new work but to the "affected part" of the existing building. That is the principal pedestrian entrance and the continuous accessible path of travel from it to the new area. This is a common surprise on fitouts in older Melbourne buildings, and it is best identified at design stage.

Which version of the building code applies?

NCC 2025 has applied to new building work in Victoria since 1 May 2026, with transitional arrangements for projects certified as having made substantial progress before then. Make sure your designer and building surveyor are working to the edition that applies to your permit.

Do office fitouts need a planning permit?

Usually not for purely internal work, but check three things. First, whether your proposed use is allowed in the zone without a permit. Second, signage: new business signs are controlled under Clause 52.05 of the planning scheme. Third, car parking: an intensified use can trigger requirements under Clause 52.06. Heritage overlays can occasionally control internal work, so check the planning property report for your address.

What does the approval process look like?

1. Brief and measure-up: confirm the scope, lease requirements and landlord design criteria.
2. Early surveyor review: a building surveyor confirms whether a permit is needed and flags essential safety measure impacts.
3. Design documentation: architectural, services and fire engineering drawings as required.
4. Landlord approval: most leases require the landlord's written consent to the design.
5. Building permit: issued by the relevant building surveyor before work starts.
6. Construction and inspections: mandatory inspections as set by the permit.
7. Completion: an occupancy permit or certificate of final inspection, plus updated essential safety measure records.

What happens if you skip the permit?

Work done without a permit can be ordered to stop, altered or removed. It can also delay your occupancy, complicate insurance claims and cause problems with your landlord at the end of your lease. Retrospective approval is not guaranteed and is usually slower and more expensive than doing it properly at the start.
