Choosing a Commercial Fit-Out Builder in Canberra

Last updated October 2026.

You've signed the lease, or you're about to. The landlord has handed you a fit-out guide as thick as a phone book, your opening date is already in the diary, and every week the space sits empty is a week of rent with no customers. The builder you choose will decide whether that date holds.

A fit-out isn't a small house build. It runs on someone else's building, under someone else's rules, often while the neighbours keep trading. This guide covers how to choose a commercial fit-out builder in Canberra, what to ask before you sign, and where fit-outs usually go wrong.

How to choose a commercial fit-out builder

Choose a builder who holds the right ACT licence, has done fit-outs in occupied buildings, will manage landlord, strata and authority approvals for you, knows the NCC and accessibility rules, can stage and run after-hours work, and gives you a fixed price tied to a written program. Then check their references on time and budget, not just finish quality.

Why fit-outs are different

On a house, the builder controls the site. On a fit-out, almost nothing is fully in your control or theirs:

• The landlord or owners corporation has to approve the design, the contractors and often the working hours.

• Fire systems, air conditioning and building management systems usually belong to the base building, and many landlords insist their own contractors touch them.

• Loading docks, lifts and car parks are shared, and they have to be booked.

• Other tenants are trading next door, above or below, so noise, dust and smells have to be managed.

• Your lease start date, rent-free period and opening date set a hard deadline.

A builder who mainly does homes may build beautifully, but miss the parts of a fit-out that cause delays. Ask how many fit-outs they've done in occupied buildings, not just how many projects they've finished.

Landlord and strata approvals

Most delays start here, before anyone picks up a tool.

Almost every commercial lease requires landlord approval of your fit-out drawings before work starts. Shopping centres and office buildings usually have a fit-out guide or tenancy design criteria that set out what's allowed: ceiling types, shopfront details, signage, services, finishes and which contractors must be used for fire and mechanical work. In a strata building, the owners corporation may need to approve the works too.

Expect the landlord to ask for:

• Design drawings and specifications for approval

• Your builder's licence, insurances (public liability cover of $10 to $20 million is common) and safety documents

• A construction program and work method statements for higher-risk work

• Details of any work to fire services, mechanical services or the structure

• A bond, and an agreed make-good standard for when the lease ends

A good fit-out builder reads the fit-out guide and lease conditions before the design is finished, not after the landlord rejects it. Ask who will prepare and lodge the approval package, and how long they allow for landlord review in the program.

In Canberra, there's one more check. Land is leasehold, and the purpose clause in the Crown lease says what the building can be used for. If you're putting a medical suite into a shopfront, or a café into an office, make sure the lease allows that use before you sign anything.

Building approval, the NCC and accessibility

Building approval

Many fit-outs need building approval from a licensed building certifier in the ACT, especially where the work changes how a space is used, moves or adds walls that affect fire separation or exits, or alters services. Some minor internal work is exempt, but don't assume yours is. Your builder should confirm the approval pathway with a certifier early, because it affects the program.

The National Construction Code

Commercial fit-outs have to comply with the National Construction Code. For most tenancies that means fire safety, exits and egress, emergency lighting and exit signs, fire separation, sanitary facilities and energy efficiency. A change of use, like turning an office into a café or clinic, can change the building's class under the NCC and trigger extra requirements.

Accessibility and the DDA

The Disability Discrimination Act and the Disability (Access to Premises — Buildings) Standards apply to new building work in most commercial buildings. When a fit-out needs building approval, the access requirements apply to the new work, and often to the path of travel from the building's main entrance to your tenancy. That can mean ramps, door widths, circulation space, accessible toilets and signage.

These requirements can add real cost, so they need to be designed in from the start. Ask every builder how they'll check NCC and access compliance before the drawings are approved, not during construction.

After-hours work and staging

If you're fitting out a new space, you may have it to yourself. But if you're renovating a space you already trade from, or working in a busy centre or office building, the program has to work around other people.

Common approaches include:

• After-hours work for noisy or disruptive jobs like demolition, core drilling, cutting and floor grinding, booked with the centre or building manager and kept within ACT noise rules.

• Staged works, where the space is split into zones so part of the business keeps trading while another part is built, then you swap.

• Weekend shutdowns for work that has to happen with services isolated, like fire system changes or switchboard upgrades.

• Temporary hoardings to keep the public area tidy and safe, and to keep dust in.

After-hours work costs more, because labour rates are higher. But it can be cheaper overall than closing your doors. A good builder will price both options and show you the difference.

What a staged fit-out looks like

Here's a typical example of how we stage a fit-out in an occupied building. Say a medical practice wants to upgrade its consulting suites and reception without closing.

• Before work starts: the lease, fit-out guide and building rules are reviewed, the design is checked against the NCC and access standards, and the landlord, certifier and base-building contractors are booked in.

• Stage 1: new consulting rooms are built behind a temporary wall while the old rooms stay open. Noisy work happens after hours.

• Stage 2: staff move into the new rooms over a weekend, and the old rooms are rebuilt as treatment and storage space.

• Stage 3: reception is rebuilt over a long weekend with a temporary front desk set up nearby, and fire and mechanical changes are tested before Monday.

• Handover: compliance certificates, warranties and manuals are handed over, along with a walkthrough of the new space.

The practice never closes, and patients mostly notice the new reception on the way out.

Questions to ask before you sign

1. What ACT licence do you hold, and does it cover this type of building?

2. What fit-outs have you done in occupied buildings? Ask for two or three references and call them.

3. Who handles landlord, strata and certifier approvals? And who pays if a submission is rejected?

4. Is the price fixed? What's excluded, and what are the provisional sums and allowances?

5. Can I see the program? A real fit-out program works backwards from your opening date, with approvals, lead times and after-hours work shown.

6. How will you handle after-hours and staged work? And how is it priced?

7. Who will run the site day to day, and how often will I get updates?

8. What's handed over at the end? Certificates, warranties, manuals and as-built drawings.

Red flags

• A low price with a long list of exclusions or big provisional sums

• No program, or a program that starts on site before approvals are in place

• No mention of the landlord's fit-out guide or the NCC

• "We'll sort approvals out as we go"

• No commercial references, or references they don't want you to call

How we approach fit-outs

At Deol Built, we take on small to medium office, retail, medical and hospitality fit-outs, where one fixed price and one site supervisor still make sense. We review the lease, the fit-out guide and the building rules before design is finished, coordinate landlord, strata and authority approvals as one package, and build the program backwards from your opening date.
