Prices are estimates based on typical WA market rates in 2026 and vary by fitout tier, tenancy condition, base building services capacity, accessibility and fire compliance obligations triggered by the work, building access and after-hours restrictions, and location across metropolitan Perth or regional WA. Building work generally requires a building permit under the Building Act 2011, preceded by a certificate of design compliance from a registered building surveyor. Building work above the relevant value threshold requires a registered building contractor. Electrical, plumbing and gas work require the relevant licensed trades. Always obtain a written quote, confirm what approvals are included, and check public liability insurance.

Office Fitout WA 2026 - Get Free Quotes

An office fitout in Western Australia is a building project rather than a decorating exercise, and the approvals framework here catches out tenants who have fitted out elsewhere. A building permit generally applies, and it must be preceded by a certificate of design compliance from a registered building surveyor. Change of use can trigger a fresh occupancy permit. Alongside that sit accessibility obligations, fire and ventilation reconfiguration, and the base building capacity limits that quietly decide what is actually possible in a tenancy. Costs range from a light refresh through to premium fitouts. Post your job on The Quote Yard to get quotes from WA commercial builders and fitout contractors.

What an Office Fitout Covers in WA

An office fitout converts a shell or an outdated tenancy into a working environment, and the scope is wider than most first-time clients expect. The visible components are partitions, ceilings, flooring, joinery, paint and furniture. The invisible components are the electrical distribution, data cabling, mechanical services, fire systems, accessibility provisions and the approvals that permit all of it. Budgets are usually set against the visible half and blown by the invisible half. That is not a failure of estimating so much as a failure of scoping, and it is entirely avoidable with a decent brief.

Fitouts are commonly graded by tier. A cosmetic refresh changes finishes without touching the layout, running four hundred to eight hundred dollars per square metre. A mid-range fitout introduces new partitions, meeting rooms, services alterations and joinery at nine hundred to one thousand eight hundred. A high-end fitout with bespoke joinery, feature ceilings, integrated audiovisual and premium finishes runs one thousand eight hundred to three thousand five hundred. The tier is a useful shorthand but the real cost driver is how much of the base building you disturb.

Category A and Category B are terms you will hear in the Perth market and they describe different things. Category A is the base condition a landlord provides or a speculative fitout done to make a tenancy lettable, typically covering ceilings, lighting, basic air conditioning distribution and floor finishes. Category B is the tenant's own fitout layered on top, covering partitions, workstations, meeting rooms, joinery and branding. Knowing which you are receiving and which you are paying for is the first thing to clarify in any lease conversation. Agents use the terms loosely. Ask for a written schedule of what the landlord is actually providing. A brochure description is marketing, not a specification, and the difference between them is frequently worth a hundred thousand dollars.

Perth's office stock spans a wide range and the building age drives the difficulty more than the tenancy size. Newer CBD towers have generous services capacity, defined tenant fitout guidelines and building management accustomed to fitout works. Older stock in West Perth, Subiaco and the suburban office parks frequently has constrained electrical supply, limited ceiling void, original services and no fitout guide at all. The same design costs materially more to deliver in the second case. Two identical briefs in two buildings a block apart can differ by thirty percent on price for reasons that have nothing to do with the design.

The professional team on a fitout of any scale includes more parties than a client expects. A designer or architect produces the layout and documentation. A registered building surveyor issues the certificate of design compliance. A registered building contractor delivers the work. Specialist consultants may cover mechanical, electrical, fire and acoustics depending on complexity. Trying to compress this into a single builder handling everything works on small refreshes and stops working quickly as scope grows. The design-and-construct model is legitimate and often efficient, but it should be a deliberate choice rather than the result of nobody engaging a designer.

Perhaps the most useful framing is that a fitout is a construction project with a tenant living inside the commercial consequences. Delays cost rent on two premises simultaneously. Approval problems stop occupation entirely. Services shortfalls discovered mid-build produce variations at the worst possible moment. Almost everything that goes wrong on a fitout was knowable earlier, which is why the front end of the process deserves more attention than it usually receives.

Approvals, Permits and the WA Framework

Western Australia regulates building work under the Building Act 2011 and the Building Regulations 2012, administered by Building and Energy within the Department of Mines, Industry Regulation and Safety. The framework differs from several eastern states in a way that trips up national tenants and interstate project managers. Before a building permit application can be made to local government, the proposed work must be certified as compliant by a registered building surveyor. That surveyor issues a certificate of design compliance, and the permit application cannot proceed without it. The surveyor is engaged by the applicant rather than appointed by the council.

This sequencing matters practically. The building surveyor is engaged early and reviews the design against the National Construction Code and the applicable standards before anything is submitted. Design problems surface at that point rather than after a permit refusal. Tenants used to a system where the council assesses the design directly sometimes leave the surveyor engagement too late and lose weeks. Budget two thousand five hundred to fifteen thousand dollars for design compliance and permit costs depending on scale.

Not every fitout needs a building permit. Purely cosmetic work that does not alter the building fabric, the fire safety measures or the services generally does not. Painting, recarpeting and replacing loose furniture sit comfortably outside. Once you are building partitions, altering ceilings, changing egress paths, modifying services or affecting fire compartmentation, you are doing building work and the permit question is live. The honest answer from a contractor early is worth more than an optimistic one. A permit obtained late is inconvenient. Work completed without one that should have had one is considerably worse, because it surfaces during a sale, a lease assignment or an insurance claim.

Occupancy permits are the WA-specific issue most likely to cause a genuine problem. Class 2 to Class 9 buildings require an occupancy permit before lawful occupation, and that permit is granted on the basis of the building as approved. A fitout that changes the use of a tenancy, or that materially alters the approved configuration, can require an occupancy permit for the new arrangement. Change of use from office to medical, childcare, food service or education is the common trigger, as is any change altering the number of people the space is designed to hold.

This deserves emphasis because the consequences are commercial rather than technical. A business that completes a fitout, moves in and then discovers it lacks a valid occupancy permit for the new use is occupying premises it should not be occupying. Insurance, licensing for the business activity and the lease itself can all be affected. Establishing the occupancy permit position during due diligence rather than after fitout is straightforward and takes one conversation with a building surveyor. Do it before signing rather than before moving in.

Builder registration applies where the work exceeds the relevant value threshold, under the Building Services (Registration) Act 2011. A contractor offering substantial building work without holding registration is offering work outside the legitimate scope, and the client carries the consequences. Registration status can be checked through DMIRS, and general service information is available through the WA Government. Verify it rather than assuming it, since the consequences of not doing so fall on the client rather than the contractor.

Lease Terms, Landlord Consent and Make Good

Landlord consent is required for fitout works in essentially every commercial lease, and the conditions attached to that consent shape the project. Managed buildings typically issue a tenant fitout guide covering permitted works, approved contractors, insurance requirements, working hours, protection of base building finishes and the process for submitting drawings. Reading this before designing rather than after is the difference between a smooth approval and a redesign. Ask for it at the point of enquiry, not after the lease is executed. Some buildings will not release it until a lease is signed. That is itself worth knowing, and worth pushing back on.

Base building services capacity is the single most important thing to establish before signing a lease, and it is the thing most often left until after. Every tenancy has an allocated electrical supply, an air conditioning capacity and a data infrastructure position set by the building. A fitout that exceeds any of them triggers either a workaround or an upgrade with its own cost and timeline. Get the available capacity confirmed in writing during negotiation rather than after the drawings are done. A landlord reluctant to put it in writing is telling you something about the building.

Incentives are common in the Perth office market and frequently include a fitout contribution from the landlord. The detail matters more than the headline number. Whether the contribution is paid on completion or progressively, what documentation is required to claim it, whether it is treated as a rent abatement or a capital payment, and whether the works become the landlord's property at lease end all affect the real value. These are questions for your accountant and lawyer rather than for the fitout contractor. The contractor can tell you what the works cost. Only your advisers can tell you what the incentive is actually worth to you after tax and at lease end.

Make good is the obligation almost nobody reads at lease signing and everybody confronts at expiry. The clause typically requires the tenancy to be returned to a defined condition, which may mean removing partitions, reinstating ceilings and lighting, making services safe, patching and repainting. Costs run one hundred and fifty to five hundred dollars per square metre. On a large tenancy that is a substantial and entirely foreseeable liability. Businesses are regularly surprised by a six figure make good on premises they were about to leave, which is a strange thing to be surprised by given it was written into the lease they signed.

The time to negotiate make good is at lease commencement, when you have leverage, not at expiry when you do not. Options worth pursuing include a cash settlement in lieu of works, agreement that specified improvements may remain, or a defined schedule of condition agreed at the outset so the standard is not disputed later. Photographic records of the tenancy condition before fitout are cheap insurance and take an afternoon. Date them, store them somewhere that will survive a change of facilities manager, and photograph the ceiling void as well as the floor.

Where a business is planning both a new fitout and a make good on the premises being vacated, running them as one procurement makes sense. The same contractor can often deliver both, sequencing the make good after the move rather than before it. Related trades including commercial cleaning, commercial painting and demolition and strip-out all appear in the make good scope. Pricing them together is usually cheaper than sequentially.

Accessibility Obligations

Accessibility is a legal obligation rather than a design preference, and it is frequently underestimated on fitout budgets. The National Construction Code sets access requirements for new work, referencing AS 1428.1 for design for access and mobility. Separately, the federal disability discrimination framework and the Premises Standards impose obligations on building owners and occupiers. A fitout that creates a new barrier, or that fails to address one it disturbs, is a genuine exposure. Complaints under the discrimination framework are made by individuals rather than detected by inspection. The risk does not diminish with time the way an unnoticed technical defect might.

The elements that most often drive cost are the accessible sanitary facility and the continuous accessible path of travel. An accessible toilet requires specific dimensions, fixture positions, grab rail placement, door swing and circulation space, and retrofitting one into an existing tenancy can be expensive. The path of travel covers entry, corridors, door widths, thresholds, floor surfaces and any level changes. Accessibility upgrades commonly run eight thousand to eighty thousand dollars. The spread reflects whether an accessible facility already exists in a serviceable position or has to be created from nothing in a tenancy with fixed drainage.

Triggering the obligation is where the surprises happen. Substantial alteration to a building or part of it can bring accessibility requirements into play for the affected area and sometimes for the path of travel serving it. This means a fitout in an older building with a non-compliant entry can find itself responsible for addressing the entry. The building surveyor identifies this during design compliance review, which is another reason to engage them early rather than late. Discovering a shared entry upgrade obligation after the fitout budget is fixed is a bad afternoon. Ask the surveyor to flag any path of travel implications at concept stage, before the layout has hardened and before anyone has committed to a move date. Long lead finishes are the usual culprit, since commercial carpet tile from Interface, Shaw or Godfrey Hirst and ceiling systems from Armstrong, USG Boral or Knauf are all readily available in Perth but not always in the colour or run you want at short notice.

Beyond the minimum, there is a practical business case for going further. Accessible design serves employees who acquire injuries or conditions during their employment, visitors and clients with mobility limitations, and an ageing workforce. Wider circulation, better lighting, accessible meeting rooms and considered acoustic treatment all improve the space for everyone. Treating accessibility as a floor rather than a ceiling produces better workplaces at modest incremental cost. It also reduces the chance of a future fitout inheriting the problem and paying to solve it under time pressure.

Acoustic performance sits alongside accessibility as a comfort factor that determines whether a fitout succeeds. Open plan offices consistently generate complaints about noise and distraction, and the remedy is designed rather than added afterwards. Ceiling absorption, partition construction to the underside of the slab where privacy is needed, floor finishes and dedicated quiet spaces all contribute. Partitions stopping at the ceiling grid provide visual separation and almost no acoustic separation, which surprises people constantly. Our soundproofing installation page covers the treatment options in more detail.

Base Building Services and Capacity

Electrical capacity is the constraint that most often reshapes a fitout design. A tenancy has an allocated supply, and modern office density with high workstation counts, kitchen appliances, server equipment and increased air conditioning load can exceed what an older building allows. The remedy is either load management, a distribution board upgrade, or an application to increase the tenancy allocation. Establishing the position early avoids a redesign, and a commercial electrician can assess it quickly. Ask for the assessment before the layout is locked rather than after.

Mechanical services capacity follows the same pattern with an additional wrinkle. Changing an open plan floor into cellular offices changes the air distribution requirements completely, because supply and return paths designed for an open volume do not serve enclosed rooms. Occupancy changes also alter the outdoor air requirement. A fitout that adds partitions without addressing the mechanical distribution produces rooms that are too hot, too cold or stuffy. This is the single most common post-occupancy complaint on Perth office fitouts. Our commercial air conditioning page covers the reconfiguration.

Data and communications infrastructure should be designed rather than improvised, because it is the system most disruptive to retrofit. Cable pathways, the communications room location and its cooling and power, the cabling standard, and the certification testing that proves the installed channel meets specification all need specifying. Coordinating with commercial data cabling at design stage costs a fraction of adding capacity afterwards, and wireless coverage depends on the cabling being right. Neither can be fixed cheaply after the ceilings close.

Sequencing determines whether services work goes smoothly or badly, and the rule is simple. Everything above the ceiling goes in before the ceiling closes. Electrical rough-in, data cabling, mechanical ductwork, fire services alterations and any structural work all precede the ceiling. A programme that closes ceilings before all services are complete guarantees they will be reopened. That is slow, expensive and produces a worse result, because a reopened ceiling rarely sits as well as an undisturbed one.

Kitchen and amenity areas concentrate services and deserve early attention. A staff kitchen needs water supply, waste, appropriate electrical circuits for appliances, ventilation and often a dishwasher connection. Waste connection is the constraint on tenancy floors, since drainage runs where the building allows rather than where the design prefers. Anyone planning an amenity area away from existing wet services should confirm the drainage route before finalising the layout. Falls, floor build-up and slab penetration all follow from that decision. Early commercial plumbing input is worth having.

Fire, Ventilation and Compliance Changes

A fitout changes the building's fire safety configuration and the obligation to address that sits with the works. New partitions change egress paths, which means emergency and exit lighting positioned for the previous layout may no longer provide the required coverage. Exit signage can end up directing occupants toward a wall. This is a compliance failure rather than an inconvenience. It is found during design compliance review if the surveyor is engaged properly, and found by an occupant during an evacuation if not.

Smoke detection coverage is affected by partitioning in the same way. Detectors positioned for an open floor may leave newly enclosed rooms uncovered, and detector spacing rules apply to the compartments as built rather than as originally designed. Sprinkler head positions can be obstructed by new ceilings, bulkheads or high storage. All of this needs assessing against the new layout rather than assumed to carry over. Coordinating with the commercial fire compliance programme means the building's servicing contractor knows what changed.

Service penetrations through fire rated elements are the most commonly created and least commonly rectified compliance defect on any fitout. Every cable, pipe and duct passing through a fire rated wall or floor must be sealed with a tested system maintaining the rating. On a busy fitout with several trades working simultaneously, unsealed penetrations accumulate quickly. Requiring a penetration register and sign-off as a condition of practical completion is straightforward and prevents a permanent problem. Without it, nobody owns the sealing and everybody assumes somebody else did it.

Ventilation obligations change with occupancy and use. Outdoor air rates are set by the space type and the number of people it serves, so increasing density or converting a storeroom into a meeting room changes the requirement. Buildings frequently pass this test in their original configuration and fail it after a fitout that nobody assessed. Measuring rather than assuming is the only reliable approach, and it is inexpensive relative to reworking a mechanical system after occupation.

Evacuation diagrams and emergency planning need updating whenever the layout changes, and this is almost universally forgotten. A diagram showing the previous floor plan actively misdirects people during an evacuation, which is worse than having none. Updating diagrams costs a few hundred dollars each and takes days. Building it into the fitout completion checklist means it actually happens rather than remaining someone's intention. The same applies to warden training where the layout change is significant.

Programme, Site Access and Trade Sequencing

Fitout programmes in occupied buildings are shaped by access rules more than by the work itself. Managed buildings restrict working hours, require inductions, control loading dock and lift access, limit noisy work to defined windows and often mandate that certain trades be drawn from an approved list. A programme built without reference to these rules is fiction. The building manager should be consulted before the programme is finalised rather than after. They will also tell you which contractors have worked in the building successfully, which is useful intelligence freely given.

After-hours work is common on Perth CBD and West Perth fitouts and carries a labour premium that needs to be in the budget from the start. Noisy demolition, core drilling, anything affecting base building services and work in common areas typically happens outside business hours. A contractor who has priced a metropolitan tower fitout on daytime rates has either negotiated something unusual with building management or has not read the building rules. Ask which. The answer determines whether the programme is achievable.

Construction projects above the relevant value threshold require the appointment of a principal contractor under the work health and safety framework, carrying defined duties for site safety, coordination and documentation. The Work Health and Safety Act 2020 and its regulations govern this in Western Australia, and current guidance is published by WorkSafe WA. On a tenant-managed fitout with several separately engaged trades, establishing who holds that role is essential rather than optional. Assuming the largest trade has picked it up is not a safety system.

Trade sequencing on a fitout follows a familiar order and compressing it produces rework. Demolition and strip-out first, then structural and framing, then services rough-in above ceiling, then ceilings, then partition linings, then flooring, then joinery, then finishing trades, then furniture and commissioning. Our demolition services and carpentry services pages cover the early stages. Finishing trades including interior painting follow once the linings are complete.

Long lead items should be identified and ordered at design stage rather than when the programme reaches them. Bespoke joinery, feature lighting, specialist glazing, custom furniture, mechanical plant and switchgear all have lead times that can exceed the entire construction programme. A fitout delayed six weeks waiting for a reception desk is a common and avoidable outcome. The contractor should produce a long lead schedule as part of the programme, and it should be reviewed at design sign-off rather than at site start. Substituting an equivalent product is far easier before it has been documented and approved.

Commissioning and handover deserve real time in the programme rather than the day before move-in. Mechanical balancing, controls setup, data certification, fire system testing, accessibility verification and defect rectification all take longer than anyone allows. The documentation package including as-built drawings, warranties, operating manuals and compliance certificates should be a condition of final payment rather than a request made afterwards. Chasing it once the contractor has been paid in full is a well-known and losing exercise.

Older Buildings, Heritage and Asbestos

Asbestos is a live consideration in a great deal of Western Australian commercial stock and the trigger point is straightforward. Workplaces constructed before the end of 2003 are required to have an asbestos register, and fitout work is one of the most reliable ways to disturb asbestos containing material. Wall linings, ceiling tiles, vinyl floor backing, electrical backing boards and fire door cores are common locations. Any fitout in an older building should begin with the register rather than with the demolition. Ask the landlord for it at the point of enquiry. They are the party most likely to hold it, and their reaction to the question is informative in itself.

Where the register does not exist, and on older Perth commercial buildings it frequently does not, an inspection is the starting point rather than an optional extra. Identification costs far less than the consequences of uncontrolled disturbance, which include stopping the site, notifying the regulator and remediating. Licensed removal costs three thousand to forty five thousand dollars depending on the material and extent. Our asbestos testing and inspection and asbestos removal pages cover the process. Build the possibility into the programme as a contingency rather than treating it as an event that will not happen, because on pre-2004 stock it frequently does.

Heritage listing constrains what can be done and is more common in WA commercial property than tenants expect. Fremantle carries an unusually dense concentration of heritage commercial buildings, and the Perth CBD, Guildford, Northam, York and other centres all have listed stock in commercial use. Where a building is listed, alterations affecting heritage fabric require approval. That process runs on its own timeline independent of the building permit, and the two do not automatically align. Assuming they will is how heritage projects lose a quarter.

Working within a heritage building is entirely achievable and often produces excellent workplaces, but it requires the constraints to be understood at concept stage. Original ceilings, cornices, joinery, windows and floors may need retaining. Services routing becomes harder without ceiling voids or accessible wall cavities. Reversibility is often expected, meaning new work should be removable without damaging original fabric. A designer experienced in heritage work saves considerable time and expense.

Older buildings generally, listed or not, present a familiar set of surprises worth budgeting for. Floor levels are rarely true, which affects partition setout and flooring. Existing services are often undocumented and occasionally live where drawings show them dead. Structural capacity may be unclear. Ceiling voids are shallow or absent. A pre-construction investigation on an older tenancy, including a building inspection, converts unpleasant surprises into priced allowances.

Strata Titled Office Buildings

A significant share of WA office accommodation sits in strata titled buildings, particularly suburban office parks and smaller professional suites. Fitout in these buildings requires strata company authorisation in addition to any landlord consent, and the two are separate approvals. Work affecting common property, including anything touching structural elements, common services, external appearance or shared areas, generally needs a resolution rather than an administrative approval. Confirm which applies before committing to a programme.

Timeline is the practical consequence and it is regularly underestimated. Strata companies meet on their own cycle. A fitout depending on a resolution at the next general meeting is a fitout waiting for that meeting, and the meeting may be months away. Where a business has committed to a move date, this delay is expensive. Establishing the authorisation requirement and the meeting schedule at the start of planning avoids the problem entirely.

Services capacity in strata office buildings is frequently tighter than in institutionally owned stock, because the buildings are often older and upgrades require collective agreement. A lot owner wanting additional electrical capacity may be seeking a change to common property infrastructure serving everyone. This is achievable but slow, and it needs raising early. Related common property arrangements including strata plumbing follow similar authorisation patterns, so a scheme that handles one service well usually handles the rest predictably.

Make good in strata buildings carries an additional dimension, since the obligation may run to both the landlord under the lease and the strata company in respect of common property. Anything installed on or through common property, including external plant, signage, cabling routes and penetrations, may need removing and reinstating. Recording what was approved and on what terms at installation makes the eventual removal straightforward rather than contested. It also protects a subsequent owner of the lot who inherited the installation without the paperwork, which happens more often than anyone plans for.

What to Look Out For

Establish early whether a building permit is required and who is responsible for obtaining it, because this is the most common gap in fitout quotes. A price that excludes design compliance, permit fees and the building surveyor's involvement is not comparable with one that includes them. Ask directly whether a certificate of design compliance is needed, who is engaging the surveyor, and whether the fee is in the quoted price. Three short questions. They separate a real price from an attractive one, and they take about a minute to ask.

Confirm the occupancy permit position if the fitout involves any change of use. This is the WA-specific issue most likely to produce a serious problem and it is entirely avoidable. A business converting an office tenancy to medical, childcare, education or food service should have this resolved during due diligence. A contractor who has not raised it on a change of use project may not have encountered it before, which is a reasonable thing to establish before appointing them.

Be wary of quotes that make no allowance for base building services capacity. The assumption that existing electrical, mechanical and data infrastructure will accommodate the new design is exactly that, an assumption, and it is wrong often enough to matter. Ask what the design assumes, whether the capacity has been confirmed with the building, and who bears the cost if it turns out to be insufficient. Vagueness here becomes a variation later, invariably at the point where you have least room to move. Pin it down early.

Check that accessibility and fire compliance are addressed rather than assumed away. A fitout in an older building may trigger accessibility work on elements outside the tenancy, and any layout change affects emergency lighting, exit signage, detection coverage and evacuation diagrams. These are not optional and they are not cheap to retrofit after occupation. A quote silent on all of them has either resolved them quietly or ignored them entirely, and it is worth finding out which before signing.

Get the scope in writing covering the registered entity performing the work and its registration number, what is included and specifically excluded, the approvals scope and who obtains them, the design and documentation deliverables, base building capacity assumptions, long lead items and their programme impact, the site access and working hours assumptions, the commissioning and handover documentation, defects liability period, and the payment schedule against defined milestones. Substantial deposits before design is complete are not normal on commercial fitout. Progress payments tied to defined milestones with a retention held until the defects period expires is the standard arrangement. Departures from it are worth questioning before signing.

How to Get Useful Quotes

Quote quality depends almost entirely on documentation quality, and this is where clients most often economise to their own cost. A fitout tendered from a sketch produces prices built on different assumptions, which are not comparable and which all become variations. A fitout tendered from a proper drawing set with specifications and a finishes schedule produces prices for the same thing. Design and documentation at five to twelve percent of the build cost is the best value spend on the project. It is also the first thing cut when a budget looks tight, which is precisely backwards.

Provide the building context alongside the design intent. The building name and age, floor level and area, the tenant fitout guide if one exists, the lease terms relevant to works and make good, known services capacity, the asbestos register for older buildings, and any strata arrangements all shape the price. If you have base building drawings, share them. Their absence means every tenderer prices the same uncertainty, and they will each price it differently, which makes the responses incomparable.

Site visits are essential and should include the ceiling void, the tenancy switchboard, the communications room and the path from the loading dock. What is above the ceiling determines a great deal about what the fitout costs and cannot be assessed from a floor plan. A contractor who quotes a fitout without lifting a ceiling tile is pricing hope. The visit is also where the base building constraints surface, which is exactly when you want to hear about them.

Putting the brief through The Quote Yard reaches several WA commercial builders and fitout contractors with the same information, which makes proposals genuinely comparable. Related scopes are covered on our builder and joinery pages. Businesses fitting out retail space should see retail shopfitting instead, since the approvals and trading hour constraints differ. Builders and fitout trades can see what is currently open on the WA tradie job leads board. Every trade a fitout touches is listed on our WA services hub.

Insurance, Warranty and Australian Consumer Law

Insurance on a fitout has more moving parts than most clients realise. The contractor should hold public liability cover appropriate to commercial construction, evidenced by a current certificate of currency, and workers compensation where staff are employed. Contract works insurance covering the works themselves during construction is a separate policy and someone needs to hold it. The building's own insurer should also be notified, since most managed buildings require this as a condition of consent. Check who is responsible for that notification, because it falls between parties more often than it should.

Defects liability is the fitout equivalent of a warranty period and is usually defined in the contract rather than left to general law. Twelve months is common on commercial fitout, during which the contractor rectifies defects arising from the work. Retention of a percentage of the contract sum until the defects period expires is standard practice. Agree it at contract stage rather than negotiating afterwards, when the leverage has moved.

Product warranties sit separately and vary widely across the components in a fitout. Flooring, ceiling systems, partitions, joinery, lighting, mechanical equipment and furniture each carry their own manufacturer terms. Assembling these into a single handover pack is a reasonable requirement and considerably easier at completion than two years later. Make it a condition of final payment. A future facilities manager will thank you, and so will the next tenant.

Australian Consumer Law applies to fitout services, with guarantees around due care and skill and fitness for purpose that cannot be excluded by contract terms. Practical guidance sits with Consumer Protection WA and, at the national level, the ACCC. Applicable standards are available through Standards Australia, and businesses working through their broader approval obligations can start at ABLIS. Consulting them at concept stage is considerably more useful than at handover.

Office Fitout FAQs - WA 2026

Do I need a building permit for an office fitout in WA?
It depends on what you are doing, but more often than tenants expect. Purely cosmetic work that does not alter the building fabric, the fire safety measures or the services generally does not require one, so painting, recarpeting and replacing loose furniture sit comfortably outside. Once you are building partitions, altering ceilings, changing egress paths, modifying services or affecting fire compartmentation, you are doing building work and the permit question is live. Western Australia differs from several eastern states in the sequence. Before a building permit application goes to local government, the design must be certified as compliant by a registered building surveyor who issues a certificate of design compliance. Tenants used to councils assessing designs directly often engage the surveyor too late and lose weeks. Budget two thousand five hundred to fifteen thousand dollars for design compliance and permit costs.
What is an occupancy permit and does my fitout need a new one?
Class 2 to Class 9 buildings in WA require an occupancy permit before lawful occupation, granted on the basis of the building as approved. A fitout that changes the use of a tenancy, or materially alters the approved configuration, can require an occupancy permit for the new arrangement. Change of use from office to medical, childcare, food service or education is the common trigger. This matters commercially rather than technically. A business that completes a fitout, moves in and then discovers it lacks a valid occupancy permit for the new use is occupying premises it should not be, and insurance, business activity licensing and the lease itself can all be affected. Establishing the position during due diligence takes one conversation with a building surveyor and avoids a genuinely serious problem.
How much does an office fitout cost per square metre in WA?
Four hundred to eight hundred dollars per square metre for a cosmetic refresh changing finishes without touching the layout. Nine hundred to one thousand eight hundred for a mid-range fitout introducing new partitions, meeting rooms, services alterations and joinery. One thousand eight hundred to three thousand five hundred for a high-end fitout with bespoke joinery, feature ceilings, integrated audiovisual and premium finishes. The tier is useful shorthand but the real cost driver is how much of the base building you disturb. Building age matters more than tenancy size. Newer CBD towers have generous services capacity and defined fitout guidelines, while older stock in West Perth, Subiaco and the suburban office parks frequently has constrained supply, limited ceiling void and original services, which makes the same design materially more expensive to deliver.
What should I check before signing the lease?
Base building services capacity, in writing, before you sign rather than after the drawings are done. Every tenancy has an allocated electrical supply, an air conditioning capacity and a data infrastructure position set by the building, and a fitout exceeding any of them triggers either a workaround or an upgrade with its own cost and timeline. This is the single largest source of budget variation on office fitouts and it is entirely knowable in advance. Also read the make good clause at commencement rather than at expiry, because that is when you have leverage to negotiate a cash settlement in lieu, agreement that specified improvements may remain, or a schedule of condition so the standard is not disputed later. Get the tenant fitout guide if the building is managed, and check whether an occupancy permit issue arises from your intended use.
How much will make good cost me?
One hundred and fifty to five hundred dollars per square metre, which on a large tenancy is a substantial and entirely foreseeable liability. The clause typically requires the tenancy to be returned to a defined condition, which may mean removing partitions, reinstating ceilings and lighting, making services safe, patching and repainting. Almost nobody reads it at lease signing and everybody confronts it at expiry. The time to negotiate is at commencement, when you have leverage. Worth pursuing are a cash settlement in lieu of works, agreement that specified improvements may remain, or a defined schedule of condition agreed at the outset so the standard is not disputed later. Photographic records of the tenancy before fitout are cheap insurance and take an afternoon. In strata buildings the obligation may run to both the landlord and the strata company for anything on common property.
Does my fitout trigger accessibility upgrades?
Possibly, and this is where fitout budgets are most often caught short. The National Construction Code sets access requirements for new work referencing AS 1428.1, and separately the federal disability discrimination framework and Premises Standards impose obligations on owners and occupiers. Substantial alteration to a building or part of it can bring accessibility requirements into play for the affected area and sometimes for the path of travel serving it, which means a fitout in an older building with a non-compliant entry can find itself responsible for addressing the entry. The elements that drive cost are the accessible sanitary facility and the continuous accessible path of travel, with upgrades commonly running eight thousand to eighty thousand dollars. Your building surveyor identifies this during design compliance review, which is another reason to engage them early.
What about asbestos in an older Perth office?
Assume it is a live question on anything built before the end of 2003. Workplaces from that era are required to have an asbestos register, and fitout work is one of the most reliable ways to disturb asbestos containing material. Common locations include wall linings, ceiling tiles, vinyl floor backing, electrical backing boards and fire door cores. Any fitout in an older building should begin with the register. Where it does not exist, and on older Perth commercial buildings it frequently does not, an inspection is the starting point rather than an optional extra. Identification costs far less than uncontrolled disturbance, which means stopping the site, notifying the regulator and remediating. Licensed removal runs three thousand to forty five thousand dollars depending on material and extent.
Why does my fitout need after-hours work?
Because the building requires it, and it carries a labour premium that needs to be in the budget from the start. Managed buildings restrict working hours, require inductions, control loading dock and lift access, limit noisy work to defined windows and often mandate that certain trades come from an approved list. Noisy demolition, core drilling, anything affecting base building services and work in common areas typically happens outside business hours. A programme built without reference to these rules is fiction, so the building manager should be consulted before the programme is finalised rather than after. A contractor who has priced a Perth CBD or West Perth tower fitout entirely on daytime rates has either negotiated something unusual with building management or has not read the building rules.
How do I make sure the quotes I get are comparable?
Tender from proper documentation rather than a sketch, because quote quality depends almost entirely on documentation quality. A fitout tendered from a sketch produces prices built on different assumptions, which are not comparable and which all become variations during construction. A proper drawing set with specifications and a finishes schedule produces prices for the same thing. Design and documentation at five to twelve percent of build cost is the best value spend on the whole project, and economising there reliably costs more later. Provide the building context too, including the building name and age, floor level and area, the tenant fitout guide, lease terms relevant to works and make good, known services capacity, the asbestos register and any strata arrangements. If you have base building drawings, share them.
What happens to fire compliance when I change the layout?
It changes with the layout, and addressing it is the responsibility of the works. New partitions change egress paths, so emergency and exit lighting positioned for the previous layout may no longer provide required coverage and exit signage can end up directing occupants toward a wall. Smoke detection coverage is affected the same way, since detectors positioned for an open floor may leave newly enclosed rooms uncovered. Sprinkler heads can be obstructed by new ceilings, bulkheads or high storage. Service penetrations through fire rated elements are the most commonly created and least commonly rectified defect on any fitout, because several trades create them simultaneously and nobody owns the sealing. Requiring a penetration register and sign-off as a condition of practical completion is straightforward. Evacuation diagrams also need updating and are almost universally forgotten.

Prices are estimates based on typical WA market rates in 2026 and vary by fitout tier and finish level, the condition and age of the existing tenancy, base building electrical mechanical and data capacity, accessibility and fire compliance work triggered by the alterations, building access rules and after-hours working restrictions, asbestos and heritage constraints, and location across metropolitan Perth or regional WA. Building work generally requires a building permit under the Building Act 2011, and in Western Australia the permit application must be preceded by a certificate of design compliance issued by a registered building surveyor. Change of use may require a new occupancy permit. Building work above the relevant value threshold requires a registered building contractor under the Building Services (Registration) Act 2011. Electrical, plumbing and gas work require the relevant licensed trades. Asbestos removal requires a licensed removalist. Always obtain a written quote stating what approvals are included and who obtains them, and check public liability and contract works insurance.
