The difference between a fitout and a tenancy improvement is mostly a matter of who owns the work and how the lease treats the resulting installation. The two terms describe similar physical scope (interior construction work that adapts a commercial space for a tenant’s use) but they sit in different commercial and legal categories. A fitout is the tenant’s work, paid for by the tenant, owned by the tenant or by the landlord depending on the lease, and removed at lease end if the make-good clause requires. A tenancy improvement is usually the landlord’s work, paid for by the landlord, owned by the landlord, and forms part of the base building or the leased premises depending on the timing.
The distinction matters because it shapes the commercial conversation at lease negotiation and at lease end. A tenant who treats the two terms as interchangeable can miss negotiation opportunities at lease signing (where tenancy improvements paid for by the landlord avoid tenant capital cost) and at lease renewal (where a fitout the tenant paid for may not be the landlord’s automatic responsibility to refresh). Understanding which scope sits in which category is part of how tenants get the commercial outcome the lease should support.
What A Fitout Is, In The Commercial Sense
A fitout is the construction work that converts a leased commercial space from its base-building condition into a workplace ready for the tenant’s specific use. The scope includes partitions, ceilings, floor coverings, lighting, finishes, joinery, services beyond base-building provision, and any other element the tenant installs to make the space functional. The work is typically paid for by the tenant, either directly or through a fitout contribution negotiated in the lease incentive.
Ownership of the fitout varies with the lease. Most commercial leases position the fitout as the tenant’s property during the lease, with the obligation to remove it at lease end under the make-good clause. Some leases position specific fitout elements (typically the major partitions and ceilings) as becoming the landlord’s property at lease end, with no make-good obligation. Some leases convert the fitout from tenant to landlord ownership at specific milestones (a renewal, an extension, a depreciation point).
The tax treatment is part of the practical distinction. Tenants typically depreciate the fitout cost across its useful life (often 7 to 10 years for most elements, longer for some structural items) under the relevant tax rules. The depreciation runs against the tenant’s income tax, treating the fitout as the tenant’s capital asset for accounting purposes. Where the lease converts the fitout to landlord ownership mid-term, the tax treatment shifts accordingly.
What A Tenancy Improvement Is, By Contrast
A tenancy improvement, in the standard commercial usage, is improvement work to a leased tenancy paid for and owned by the landlord, typically delivered before the lease starts or as part of the lease incentive package. The work can be physical (improvements to the building shell, base-building finishes, structural changes that benefit the tenancy) or service-related (HVAC upgrades, services capacity increases, infrastructure additions). The defining characteristic is that the landlord pays, the landlord owns, and the improvements form part of the base building or the leased premises.
The commercial logic for tenancy improvements is that the landlord invests in the building’s leasing competitiveness, either to attract a specific tenant (often a larger or longer-term tenant) or to position the building for higher rents at re-lease. The investment shows on the landlord’s balance sheet rather than the tenant’s, and the work usually does not have a make-good obligation against it.
The pattern we see most often in modern commercial leasing is the line between fitout and tenancy improvement is blurred in negotiation. Landlords sometimes contribute to fitout costs (through a fitout contribution or rent-free period applied to fitout work), which converts what would otherwise have been pure tenant cost into shared cost. The line between “fitout the tenant paid for” and “tenancy improvement the landlord paid for” can sit anywhere in the contribution depending on how the agreement is structured.
Where The Line Actually Sits In Practice
In a typical commercial lease, the line between fitout and tenancy improvement is set by three factors: who paid for the work, who owns the resulting installation, and what the make-good obligation requires at lease end.
Work paid for by the tenant, owned by the tenant during the lease, with full make-good at lease end, is unambiguously a fitout. Standard examples include partitions, ceilings, joinery, tenant-specific lighting, branded finishes, and any element specifically tailored to the tenant’s use.
Work paid for by the landlord, owned by the landlord, forming part of the base building, is unambiguously a tenancy improvement. Standard examples include HVAC upgrades the landlord undertakes to improve the building’s capacity, base-building lighting upgrades that benefit any tenant, services infrastructure additions, and any work that improves the leasable space for any future tenant.
Work paid for by the landlord through a fitout contribution, owned by the tenant during the lease, with partial or full make-good at lease end, sits in the middle. This is the most common arrangement in negotiated commercial leases. The work is physically fitout in nature, but the funding comes from the landlord and the ownership question depends on the lease’s specific wording.
Work paid for by the tenant but specifically agreed in the lease to become the landlord’s property at lease end is unambiguously a fitout-becoming-tenancy-improvement, and the make-good obligation is reduced or removed for the specific items. The defit and make-good scope reflects this distinction directly.
Why The Distinction Matters At Lease Signing
At lease signing, the distinction shapes the financial structure of the deal. A fitout contribution from the landlord typically counts as a reduction in the effective rent rather than as a capital injection; the tenant funds the fitout against the contribution, with any shortfall coming from tenant capital. The lease’s accounting effect for both parties depends on how the contribution is structured.
A landlord-paid tenancy improvement counts differently. The landlord capitalises the work as building improvement; the tenant pays the agreed rent without any apparent contribution; the building’s improvement supports the leased rate for the term and potentially for re-lease. The arrangement can suit landlords with capital to deploy and tenants who prefer not to fund fitout work themselves.
The negotiation point at lease signing is whether the tenant’s required scope can be reframed as tenancy improvement rather than fitout, with the landlord absorbing the cost. The argument that supports it is whether the work benefits the building beyond the specific tenant’s use; HVAC upgrades, structural alterations, services capacity additions, and base-building finishes can sometimes qualify even when they were triggered by the tenant’s specific requirements.
Why The Distinction Matters At Lease End
At lease end, the distinction shapes the make-good scope and the eventual cost. Fitout work the tenant paid for and owned is typically subject to full removal under the make-good clause, with the tenant funding the defit and reinstatement. Tenancy improvements the landlord paid for and owned are typically not subject to make-good; they form part of the base building and stay in place.
The line between the two can be contested at lease end if it was not clearly drawn at lease start. A partition that was funded partly by landlord contribution and partly by tenant capital, with no explicit ownership clause, can become the subject of negotiation about whether it has to be removed. The cleaner pattern is to specify the ownership and make-good treatment of each major fitout element in the lease itself rather than leaving it to interpretation later.
The make-good clauses we see most often on commercial leases handle this through one of two approaches. Either the lease specifies that all tenant-installed work must be removed at lease end (defaulting to fitout treatment), or the lease specifies that work above a certain value or of certain types becomes landlord property at lease end (converting to tenancy-improvement treatment). Hybrid arrangements that specify item-by-item are less common but cleaner when they exist.
Renewal And Refresh: Where The Categories Intersect
At lease renewal, the distinction between fitout and tenancy improvement affects who pays for any refresh work. A tenant renewing a lease with a 7-year-old fitout typically funds any refresh work themselves; the fitout is the tenant’s property and the tenant’s responsibility. A tenant renewing into a tenancy with landlord-owned improvements typically has less direct refresh responsibility, with the landlord either maintaining the existing improvements or contributing to refresh as part of the renewal incentive.
The pattern we see most often at renewal is tenants negotiating a fitout contribution as part of the renewal incentive, which effectively converts some of the tenant’s refresh work into landlord-funded tenancy improvement. The work is still physically fitout in nature, but the funding shifts and the ownership sometimes shifts with it.
The renewal moment is one of the cleaner times to address the fitout-versus-tenancy-improvement question. Existing fitout that the tenant funded but no longer requires (because the layout has aged, because the team has changed, because the working pattern has shifted) can sometimes be converted to landlord property at renewal in exchange for adjusted lease terms, removing the eventual make-good obligation. Both parties usually have something to gain from the conversion.
Practical Decisions Tenants Should Make About The Distinction
The first decision is at lease negotiation: identify which elements of the intended fitout might reasonably qualify as tenancy improvements, and negotiate the landlord contribution accordingly. HVAC capacity upgrades, base-building lighting changes, structural alterations to accommodate the tenant’s use, and any infrastructure additions that benefit the building beyond the specific tenant are candidates for landlord funding.
The second is at fitout specification: design and specify the fitout with the make-good obligation in mind. Partitions that install cleanly and remove cleanly, finishes that revert to base condition without damage, and services modifications that can be reversed at lease end all reduce the eventual reinstatement cost. Make-good cost drivers usually favour reversible installations.
The third is at the lease’s mid-term: confirm the ownership and make-good treatment of the major fitout elements through any lease variation, renewal negotiation, or formal agreement with the landlord. The pattern we see most often on disputed make-good at lease end is the ownership question was unclear from lease start and was never confirmed during the term. The fix is to address it explicitly rather than allow ambiguity to compound.
