ACT Commercial Rent Increases: Retail vs. Commercial Leases

Unlike the rigid, CPI-linked rent caps that dominate residential tenancies in the Australian Capital Territory (ACT), commercial rent increases are generally governed by the lease contract. However, the Leases (Commercial and Retail) Act 2001 — which commenced on 1 July 2002 — imposes strict limitations on how rent can be reviewed for leases within its scope.

How Rent Increases Work

Commercial rent does not increase automatically. To raise the rent during the term of a lease (or upon renewal), the lease agreement must contain a specific rent review clause.

Rent reviews typically occur annually or on the anniversary of the lease commencement.

Scope of the Act

The Leases (Commercial and Retail) Act 2001 provides significant protections for tenants of 'retail premises' (lettable area of 1,000m² or less), 'small commercial premises' (lettable area of 300m² or less), and premises in the retail area of a shopping centre (unless they are 'large excluded premises' exceeding 1,000m² and leased to a listed public company). The Act also applies to specific tenancies such as those used by incorporated associations, charities, child care centres, and sports centres.

Protections for Covered Leases

1. Ban on 'Upward-Only' Reviews: Under Section 52 of the Act, a lease cannot contain an "upward-only" market rent review clause. If the market dictates that the rent should decrease, the lease must allow the rent to decrease.
2. Single Method of Calculation: Under Section 49, a lease provision is void if it provides for a change in rent to be calculated by more than one method (e.g., "CPI or 5%, whichever is greater") or allows the lessor to choose between multiple methods.
3. Frequency Limit: Under Section 47 of the Act, a lease provision is void if it allows rent to be changed more than once in any 12-month period after the first anniversary of lease commencement.

Common Types of Rent Reviews

When drafting an ACT commercial lease, landlords typically utilize one of three rent review mechanisms:

1. Fixed Percentage Increases

The rent increases by a pre-agreed percentage (e.g., 3% or 4%) every year. This provides absolute certainty for both the landlord and the tenant.

2. CPI (Consumer Price Index) Reviews

The rent increases in line with inflation, usually tracking the CPI for Canberra. This protects the landlord's yield against inflation but offers less predictability than a fixed percentage.

3. Open Market Rent Reviews

The rent is recalculated based on the current market rate for similar commercial properties in the ACT.

• This method is often used mid-term in a long lease (e.g., year 3 of a 5-year lease) or upon the tenant exercising an option to renew.
• If the parties cannot agree on the new market rent, Section 58 stipulates that a specialist retail valuer is appointed by agreement or, failing agreement, by the Planning and Land Authority. The valuer's decision is usually binding.

Options to Renew and Market Rent

When a tenant exercises an option to renew their lease for a further term, the rent is almost always subject to an Open Market Rent Review.

If the new rent cannot be agreed upon, the Leases (Commercial and Retail) Act 2001 outlines a formal process for appointing an independent valuer (via the Planning and Land Authority if agreement cannot be reached) to resolve the dispute before the new term commences.

Additional Territory Context for ACT

The Australian Capital Territory (ACT) operates under a specialised legal structure due to its status as the nation's capital. Commercial and retail lease relationships in the ACT are primarily governed by the Leases (Commercial and Retail) Act 2001, which commenced on 1 July 2002 and was most recently amended by the Statute Law Amendment Act 2025 (A2025-29). The Act applies to retail premises (≤1,000 m² lettable area), small commercial premises (≤300 m² lettable area), and premises in the retail area of a shopping centre (unless they are 'large excluded premises' exceeding 1,000m² and leased to a listed public company). It also covers specified tenancy types such as those used by incorporated associations, charities, child care centres, and sports centres. Landlords and tenants outside these thresholds are generally governed by the terms of their individual lease contracts, subject to the general law of contract and the Civil Law (Property) Act 2006.

All ACT commercial rent increase disputes that cannot be resolved between the parties may be referred to the ACT Magistrates Court for determination.
