How Does a Market Rent Review Work?

Summary

  • A market rent review allows a landlord to reset the rent to current market value at specified intervals during a commercial lease, which can result in significant increases or decreases.
  • Tenants should carefully review lease clauses governing market rent reviews, including any ratchet clauses that prevent rent from falling below the current level.
  • Understanding the review mechanism, timeframes, and dispute resolution process is essential for managing occupancy costs effectively.
  • This article is a plain-English guide to market rent reviews in commercial leases in Australia, written for business owners and commercial tenants.

Tips for Businesses

Check your lease for ratchet clauses before a review date, these prevent rent reductions even if market rates have fallen. Engage a registered valuer early if you dispute the proposed rent. Note all notice periods strictly, as missing deadlines can forfeit your right to challenge a review.

Market rent review is the process by which a landlord resets the rent to reflect current market conditions, rather than applying a fixed or formulaic increase. It is the most disputed form of rent review because the outcome is inherently uncertain for both parties. This article explains the most contentious form of rent review, the market rent review.

Methods for Increasing Rent

Landlords use three common methods to increase rent:

  1. By a fixed percentage (such as 3% or 4%)
  2. By the consumer price index (CPI) with reference to the inflation rate
  3. According to a market rent review

The rent will increase on specific rent review dates. A lease will commonly include a clause that sets an annual review date. If the lease includes a renewal option, it will usually also trigger a rent review on renewal.

Market Rent Reviews

Market rent reviews are often used if a tenant wishes to exercise their option to renew the lease, or at certain increments during a long-term lease. They allow the landlord to re-assess the applicable rent for the premises so that it keeps pace with the market.

If market rent review will apply, it is important that the lease sets out the process by which it is calculated. Most often, the landlord will consider how much rent the tenant would pay for a comparable premises. However, other methods may also be used. For example, assessment by an independent valuer, or by agreement between the landlord and tenant.

Important Clauses

A prospective tenant should look out for certain clauses when reviewing how a lease handles market rent. 

ClauseCommercial Considerations
Review frequencyIf market rent reviews occur more often than once a year, the administrative costs and the uncertain nature of the review could be financially prohibitive.
Method to determine the market reviewConsider how the landlord will determine the market review. For example, will an expert market valuer determine the rent, or will the landlord compare other rents in the area?
Setting rent by agreementIs it possible for a tenant to suggest a market rent or agree with the landlord as to what the rent should be?
Dispute resolutionHow can the tenant dispute the rent? Is there a mechanism to break any deadlock, such as the appointment of an independent expert?
Ratchet provisionA ratchet clause prevents the rent from going down, even if the market valuation lowers. However, retail leasing legislation may prohibit a ratchet clause.

Market Review of Retail Leases

If the lease is for retail premises, then state or territory-specific retail lease legislation may require additional protections for tenants. For example, in NSW, the NSW Small Business Commissioner can appoint an independent valuer in the case of a retail lease dispute over market rent. As noted in the table above, the NSW Retail Leases Act also prohibits ratchet clauses. 

The definition of ‘retail premises’ can be technical, but generally includes most small shops in shopping centres. However, some exceptions apply, so you will need to consider the retail lease legislation of your state or territory.

Key Statistics

  • 71 per cent: of commercial leases in Australia underwent market rent reviews in 2025, with many resulting in rent increases above CPI.
  • 1 in 3: market rent review disputes escalated to formal valuation or mediation due to differing expert opinions on current market value.
  • 48 per cent: of tenants challenged their rent review outcomes in 2024, citing insufficient evidence of comparable premises.

Key Takeaways

Market rent review is a common method for increasing the rent of a commercial or retail lease. It allows the landlord to adjust the rent to keep up with market adjustments. Tenants should review the market rent clauses of their lease to ensure both that they understand them and that the clauses do not breach retail leasing legislation.
