Building Permit for Office Fitout Melbourne | Compliance Guide

Do you need a building permit for an office fitout in Melbourne? Clear guide to when permits are required, what the process involves, and how long it takes.

One of the most common questions we hear from Melbourne businesses planning an office fitout: "Do I need a building permit?"

The short answer: almost certainly yes, for anything beyond minor cosmetic work. But the rules are more nuanced than a simple yes or no — and getting this wrong can cost you months of delays, forced demolition, and significant legal exposure.

This guide explains the permit requirements for office fitouts in Melbourne — what triggers a building permit, when a planning permit is also required, and how a design-and-construct fitout company handles the approvals process for you.

Building Permits vs Planning Permits — What's the Difference?

Many Melbourne businesses confuse building permits and planning permits. They're different approvals from different authorities — and some fitouts require both.

A building permit is issued by a Building Surveyor after reviewing your working drawings. A planning permit is issued by Council after a (sometimes lengthy) planning assessment. The two processes run separately — and you generally need planning permit approval before a building permit can be issued where both apply.

When Do Office Fitouts in Melbourne Require a Building Permit?

Under the Building Act 1993 (Victoria) and the Building Regulations 2018, a building permit is required for any work that involves:

• Structural work — anything affecting the building structure, including mezzanines, structural partitions, floor penetrations, or load-bearing changes
• Plumbing work — installation or alteration of any plumbing, drainage, or water supply (kitchenettes, bathrooms, wet areas). A separate plumbing permit is also required, issued by the plumber under their licence.
• Fire safety systems — alteration to or installation of sprinkler systems, smoke detection, fire doors, exit signage, or emergency lighting
• Partition walls — where new walls affect fire compartmentation, required egress paths, or the building's occupancy load calculation
• Change of use — if works are associated with a change in the building's use class (e.g. converting a warehouse to an office)
• Air conditioning and mechanical services — where works require penetrations, ductwork, or alterations to the base building HVAC
• New electrical switchboard or sub-board — major electrical installation work (though routine fit-off wiring by a licensed electrician under a Certificate of Electrical Safety does not require a building permit)

What Doesn't Usually Require a Building Permit?

Minor fit-off and cosmetic works typically do not require a building permit in Victoria:

• Painting and wallpaper
• Carpet and floor coverings (where no structural subfloor work is involved)
• Furniture and freestanding joinery
• Low-voltage data and communications cabling (within existing conduits/trunking)
• Replacing like-for-like fixtures in an unchanged layout

In practice, most commercial office fitouts involve at least some permit-triggering work. Even a "simple" refurbishment that adds a kitchenette or moves a partition triggers permit requirements.

When Is a Planning Permit Also Required?

A planning permit from your local council is required in addition to (or sometimes instead of) a building permit in several circumstances:

Change of Use

If you're taking a tenancy and using it for a purpose different from its current approved use, a planning permit for change of use is typically required. Common examples in Melbourne:

• Converting a retail shop to an office
• Converting an office to a food premises (café, restaurant)
• Converting a warehouse to office or retail
• Opening a childcare centre or medical clinic in a general commercial zone

Heritage Overlay

Properties within a Heritage Overlay (HO) listed in the relevant council's planning scheme require a planning permit for external works. Internal works within a heritage-overlaid building are generally exempt, but external alterations — new shopfronts, signage, added structures — need council approval. Heritage Overlays are common in inner-Melbourne councils including Boroondara, Stonnington, Yarra, Port Phillip, and Melbourne CBD fringe.

Signage

New signage on a commercial building often requires a planning permit — particularly in Activity Centre Zones, Design and Development Overlays, or Heritage Overlays. Check with your council before installing external signage as part of a fitout.

Licensed Premises (Liquor)

Hospitality fitouts seeking a liquor licence require the premises to be fit for purpose under the Liquor Control Reform Act 1998. While this isn't strictly a planning permit, liquor licence applications involve council input and must be coordinated with the fitout process.

The Building Permit Process for Melbourne Office Fitouts

Here's how the building permit process works for a typical Melbourne office fitout:

1. Working drawings prepared — Your fitout company (or architect) prepares detailed drawings showing the proposed layout, partitioning, services, and structural elements. These must demonstrate NCC compliance.
2. Building Surveyor engaged — A registered private Building Surveyor reviews the drawings and assesses NCC compliance. They may request amendments or additional documentation (structural calculations, hydraulic design, etc.).
3. Permit issued — Once satisfied, the Building Surveyor issues the building permit. Works can commence.
4. Mandatory inspections — The Building Surveyor conducts inspections at key stages (framing, pre-plasterboard, final). Inspection requirements vary by project scope.
5. Occupancy Permit / Certificate of Final Inspection — On completion, the Building Surveyor issues either an Occupancy Permit (for new buildings or change of use) or a Certificate of Final Inspection. This confirms the works are complete and compliant.

Typical building permit timeline: 2–4 weeks from lodgement of complete drawings. Complex projects or those requiring referrals (e.g. to Melbourne Water or VicRoads) may take longer. Factor this into your fitout project schedule.

What Happens If You Fitout Without a Permit?

Carrying out building work without a required permit in Victoria is an offence under the Building Act 1993. Consequences include:

• Fines: Significant financial penalties for both the building owner and the builder
• Demolition orders: The Building Surveyor can issue a notice requiring unpermitted work to be demolished or brought into compliance — at your cost
• Inability to sell or lease: Unpermitted commercial works create title encumbrances that affect the property's sale and lease value
• Insurance voidance: Property and public liability insurance may be voided if unpermitted works are found to be the cause of a loss
• Landlord liability: Your lease almost certainly requires you to obtain all permits. Failing to do so puts you in breach and could expose you to lease termination

Retrospective building permits are possible — but expensive and time-consuming. It's always cheaper and faster to get the permit upfront.

Landlord Approval: Separate to Building Permits

In addition to council and building permits, commercial tenants almost always need written landlord consent before starting any fitout works. This is a lease obligation — not a statutory requirement — but it's equally important.

Most Melbourne landlords and building managers require you to submit:

• Architectural drawings showing the proposed fitout
• Finishes schedule
• Services documentation (mechanical, electrical, hydraulic)
• Evidence of insurance (public liability, workers' compensation)
• Builder's licence details
• Proposed construction methodology and access arrangements

Landlord approval typically takes 2–4 weeks. For premium buildings (Collins Street, Southbank towers, major shopping centres), allow 4–8 weeks and expect a formal Design Review Committee process. Spacez prepares and manages all landlord submissions as part of our standard project scope.

How Spacez Manages the Approvals Process

When you engage Spacez for a Melbourne office fitout, the approvals process is managed end-to-end:

• Initial site assessment — We review your lease, identify the relevant zoning, overlay, and building classification, and flag any planning or permit triggers before you commit to a tenancy
• Working drawings — Our in-house design team produces NCC-compliant drawings suitable for building permit lodgement
• Building Surveyor engagement — We engage and manage our panel of registered Building Surveyors
• Landlord submission — We prepare the full landlord submission package and manage the back-and-forth with building managers
• Permit compliance on site — Our site managers ensure all works are constructed in accordance with the approved permit documentation
• Final inspection and certificate — We coordinate the final Building Surveyor inspection and obtain your Certificate of Final Inspection or Occupancy Permit

This means you don't need to manage architects, building surveyors, and council separately. One company, one contract, one point of accountability.

Frequently Asked Questions

How much does a building permit cost for an office fitout in Melbourne?

Building permit fees are set by regulation based on the cost of works. For a $200,000 office fitout, expect to pay approximately $1,500–$3,000 in building permit fees to the Building Surveyor, plus any structural engineering or hydraulic design fees required to support the application. Spacez includes building permit costs in our project estimates.

Who is responsible for getting the building permit — me or the fitout company?

The builder (fitout company) is typically the permit applicant for commercial fitout works in Victoria. This is standard practice and means Spacez — not you — carries the primary responsibility for lodging permit documentation and ensuring compliance. Your responsibility is to grant access and cooperate with the Building Surveyor's inspection requirements.

Does my landlord's approval replace the need for a building permit?

No. These are entirely separate processes. Landlord consent is a commercial/contractual requirement. Building permits are a statutory requirement under the Building Act. You need both. One does not substitute for the other.

How long does the total approvals process take before construction can start?

For a standard Melbourne office fitout: allow 4–8 weeks from brief to permit-ready-to-build. This covers design documentation (2–3 weeks), building permit lodgement and assessment (2–3 weeks), and landlord submission (concurrent, 2–4 weeks). Where planning permits are required, add 8–16 weeks for the council planning process.
