Fit-Out Permits

Your Commercial Fit Out Permit in Melbourne

Offices, shops, cafes and clinics

Fitting out an office, shop, cafe, clinic, gym or warehouse office? You’ll often need a commercial fit out permit in Melbourne before work starts, because a fit-out usually changes more than finishes. New partitions affect exits, new ceilings affect fire services, and new toilets or entries affect access for people with disability.

Our building surveyors help business owners, landlords, designers and builders work through the building permit. We check the use and building classification, flag what the base building needs, issue the permit and carry out the inspections through to the occupancy permit or certificate of final inspection.

When Does a Commercial Fit Out Need a Building Permit?

Building work, including alterations, needs a building permit unless an exemption applies. The Building Regulations 2018 exempt some alterations, but only where the work won’t:

  • adversely affect the structure, for example by changing floor area or height, or altering anything that supports the building
  • adversely affect an essential safety measure, such as exits, exit signs, emergency lighting, sprinklers or smoke detection
  • adversely affect the safety of the public or occupiers
  • project beyond the street alignment, or involve a building on the Heritage Register.

Many commercial fit-outs touch at least one of these. New offices and partitions change the paths to exits, new ceilings move detectors and sprinkler heads, and a commercial kitchen or mezzanine adds complexity. A change of use needs careful assessment too. Send us your layout and we’ll confirm whether a permit is required.

Change of Use and NCC Building Classes

Every building, or part of one, has a classification under the National Construction Code (NCC). Common fit-out classes include:

  • Class 5: offices used for professional or commercial purposes.
  • Class 6: shops and premises serving the public directly, including cafes, restaurants and hairdressers.
  • Class 7b: warehouses and storage.
  • Class 9a: health-care buildings, including clinics where patients may need help to evacuate.
  • Class 9b: assembly buildings, such as sports venues, theatres and schools.

Turning an office into a cafe changes the classification, and a building must not be used for a purpose other than the one it’s approved for. The regulations let the building surveyor decide how far the existing building must be upgraded for its new use.

Occupancy Permits for a New Use

An occupancy permit records a building’s approved use and classification. If your building permit says one is required, the tenancy can’t be occupied until it’s issued. For commercial buildings, it also lists the essential safety measures the owner must maintain, and how often each must be inspected and tested.

Where no occupancy permit is required, you’ll receive a certificate of final inspection instead. Either way, build the final inspection into your opening date and have plumbing and other compliance certificates from your trades ready, because the building surveyor needs the documents your permit calls for before signing off the work.

How Does the Fit-Out Permit Process Work?

Fit-out problems are cheapest to solve on paper. Our process is designed to surface issues early, ideally before you sign a lease, order joinery or book trades for your opening date.

Send your layout

Share the address, current and proposed use, floor plans (a sketch is fine at first), the landlord’s fit-out guide and any planning permit. We’ll quote and flag early risks, such as a change of use.

Assessment and advice

We confirm the classification, then check exits, fire safety, access for people with disability, toilets and energy efficiency, and tell you what the design or the base building needs to comply.

Permit issued

Once the documents comply, any required planning permit is in place and the government building permit levy has been paid, we issue your building permit and lodge it with council.

Inspections to handover

We carry out the mandatory inspections listed on your permit, review your trades’ compliance certificates, then complete the final inspection and issue your occupancy permit or certificate of final inspection.

Which Fit-Outs Do We Help With?

Every type of fit-out has its own pressure points. Common examples:

  • Office fit-outs: partitions, meeting rooms and ceilings that affect exits, detection and accessible paths.
  • Retail fit-outs: shopfronts, counters, storage and access from the street entrance.
  • Cafes and restaurants: kitchens, seating numbers, toilets and exits, plus maximum patron capacity reports if you’re applying for a liquor licence.
  • Medical and allied health: consulting rooms are often treated as offices (Class 5), but procedure areas where patients may need help to evacuate can make part of a building Class 9a.
  • Gyms and studios: often assembly buildings (Class 9b), where occupant numbers drive exit and toilet requirements.
  • Warehouse offices: office areas and mezzanines inside industrial buildings.

We also work on childcare centres and other commercial building projects.

Access, Fire Safety and Essential Safety Measures

New fit-out work must meet the Disability (Access to Premises – Buildings) Standards 2010. The standards can also require an “affected part” to be upgraded: the principal pedestrian entrance and the accessible path from it to the new work. Under a lessee concession, a tenant fitting out part of a building with more than one occupant generally isn’t required to upgrade that affected part.

Exits, exit signs, emergency lighting and sprinklers are examples of essential safety measures. The owner must keep them maintained and prepare an annual essential safety measures report, and council or the fire brigade can ask to see the records.

Planning Permits, Signage, Liquor and Parking

A building permit can’t be issued until any planning permit the project needs has been obtained, and the building permit must be consistent with it. Depending on the zone and overlays, a new use, business signage, a liquor licence or reduced car parking may need a planning permit. Check with council’s planning department before you sign a lease.

It’s also worth confirming which edition of the NCC applies. Victoria adopted NCC 2025 on 1 May 2026, and projects whose design was already under way before then may be able to use the previous edition, so tell us where your design is up to.

Frequently Asked Questions

Common questions about commercial fit-out and change of use permits.

Do I need a building permit for an office fit out?

Often, yes. New partitions, offices, ceilings or kitchenettes can affect exits, fire detection, sprinklers or access, which takes the work outside the exemption for minor alterations. Purely cosmetic work such as painting, carpet and loose furniture usually doesn’t need a permit. Send us the proposed layout and we’ll confirm what applies.

What is a change of use?

It’s when a building or tenancy is used for a different purpose from the one it’s approved for, particularly where that changes its NCC classification, such as an office becoming a cafe (Class 5 to Class 6). The new use can bring different requirements for exits, fire safety, access and toilets, and may need a planning permit too.

Will my tenancy fit-out trigger access upgrades to the whole building?

Usually not the whole building. The access standards apply to your new work and can require an upgrade to the principal pedestrian entrance and the path to your tenancy. Where a tenant fits out a leased part of a building with more than one occupant, a lessee concession means that upgrade generally isn’t required. We’ll confirm how it applies to your building.

Do I need a planning permit before a building permit?

Only if your project needs one, but if it does, it must be obtained first. The building surveyor can’t issue a building permit until any required planning permit is in place, and the two must be consistent. Our guide to building permits vs planning permits explains the difference.

What do you need from me to quote a fit-out permit?

The site address and tenancy number, the current and proposed use, existing and proposed floor plans (a sketch is fine to start), a description of the works, the estimated cost of works and the landlord’s fit-out guide if there is one. Details of the existing occupancy permit and fire services help us give you a firmer quote.
