You can apply about a rent increase dispute under the Residential Tenancies Act 1997.
The types of orders ACAT can make about a rent increase are:
- allowing the increase applied for, or a different increase that ACAT considers just
- disallowing the increase
- disallowing part of the increase.
When to apply
A lessor must apply to ACAT for approval of a rent increase when:
- a rent increase is more than the prescribed amount
- the tenant does not agree to the increase
- the residential tenancy agreement does not allow the increase.
A tenant can apply to ACAT for review of a proposed rental rate increase. An application must be made not less than two weeks before the day the rent increase starts.
What is the prescribed amount for a rent increase?
The prescribed amount is based on the rents component of the Consumer Price Index (CPI) for Canberra.
The CPI figures are published every quarter on the Australian Bureau of Statistics website.
The prescribed amount is 110% of the percentage increase in CPI for rents. That is, a lessor can increase the rent on a property by 10% more than the increase in the CPI.
To calculate the prescribed amount:
- go to the ABS website to look up the latest quarterly CPI Report for rent in the ACT
- calculate the percentage increase (PI) in the ‘index number’ over the period since the last rental rate increase
- add PI to PI divided by 10 (PI + (PI/10)) to give the prescribed amount.
How to apply
- fill in the application for resolution of a tenancy dispute form [PDF 550KB] in full
- tell us what orders you are asking for and why
- attach any relevant documents
- lodge your form
- pay the fee, unless you have an exemption, waiver or deferral.
If your application is urgent, you need to lodge an online application for interim or other orders form or printable application for interim or other orders form [PDF 56KB] at the same time as you lodge your other form.
We will take your request for urgency into account when determining the next steps in the case.
What to expect after an application is made
ACAT will let you know next steps. Usually we will:
- give a copy of the application to the parties
- send a notice to the parties about the scheduled date, time and location for a conference.
Before the conference, it is useful if the lessor gives to the tenant/s and ACAT a document that sets out how the rent increase was calculated.
Resolving the dispute
If you do not reach an agreement, the matter will progress to a hearing. We will provide directions about how to prepare for the hearing.
After a hearing, an ACAT Member will make orders about the outcome or decision.
Consent orders are made in some cases, where all the parties agree to the order that is made. Consent orders are usually made at a conference.
