What is a rent reduction order?
A rent reduction order is a formal order from your state tribunal that reduces the rent you owe for a period when you did not have full use and enjoyment of the property. It compensates you for the loss of amenity caused by an unresolved repair, unavoidable building works, or a landlord's failure to maintain the property to the required standard.
When are you entitled to a rent reduction?
You may be entitled to apply for a rent reduction when:
You cannot simply withhold rent as a form of protest or bargaining. Rent reduction orders must come from a tribunal. Withholding rent without a tribunal order is a breach of your tenancy and can result in eviction notices.
- •An urgent or significant repair has gone unresolved for an unreasonable time
- •A room or area of the property is unusable due to damage or disrepair
- •Building works (authorised by the landlord) have significantly disrupted your use of the property
- •Essential services (heating, hot water, cooking facilities) have been inoperative for a period
- •The property has a significant mould or pest infestation caused by the landlord's failure to maintain the property
How is the reduction calculated?
Tribunals calculate rent reductions based on the proportion of the property affected and the duration of the impact. For example, if a broken heater made one bedroom effectively unusable for six weeks in winter, and that bedroom represents approximately 25% of the property's value, the tribunal might order a 25% rent reduction for that six-week period.
How to apply for a rent reduction
Apply to your state tribunal using the standard residential tenancy application form. Describe the issue, how it affected your use of the property, when you reported it, and how long it persisted. Bring:
- •Copies of all written repair requests and responses
- •Photographs of the defect (dated)
- •Evidence of any costs you incurred as a result (e.g., hotel costs if the property was uninhabitable)
- •Rent payment records showing you paid in full during the affected period
Retroactive rent reduction
You can apply for a rent reduction covering a period that has already passed — you are not limited to prospective reductions. If an issue persisted for three months before you applied, the tribunal can award a reduction for that entire period. The limitation periods vary by state but are generally 3–6 years.
