NSW Rent Increase Laws: Limits & Notice Requirements

To combat escalating housing costs, New South Wales (NSW) has significantly tightened the regulations surrounding when and how often a landlord can increase residential rent. While NSW does not impose a strict percentage cap on rent hikes, the frequency of those hikes is heavily regulated.

The 12-Month Frequency Cap

As of October 31, 2024, sweeping reforms took effect across NSW limiting rent increases to once every 12 months for the vast majority of tenancy agreements.

• Periodic Agreements (Month-to-Month): Rent can only be increased a maximum of once in any 12-month cycle. Under no circumstances can there be multiple smaller increases within the same year.
• Fixed-Term Agreements (Less than 2 years): Rent can only be increased during the fixed term if the tenancy agreement already contains a specific, written term explicitly allowing it and detailing exactly how much the increase will be or exactly how it will be calculated. Even then, an increase can only occur once every 12 months.
• Starting a New Lease: If a tenant signs a new lease for the exact same property, the rent cannot be increased within the first 12 months of that new lease taking effect, preventing landlords from using lease renewals as a loophole.

Notice Period Requirements

A landlord or property manager must give the tenant a minimum of 60 days' written notice before any rent increase can take effect.

This notice must:

1. Be in writing.
2. Specify the exact amount of the proposed new rent.
3. Specify the exact date the new rent will become payable.

Important Note on Delivery Time: If the notice is sent by mail, landlords must factor in an additional 7 working days for delivery to ensure the 60 days are completely covered. An improperly served or vaguely timed notice makes the rent increase invalid and legally unenforceable.

Tenant Rights & NCAT Challenges

If a tenant is issued a rent increase notice, they DO NOT have to automatically accept it.

If the tenant believes the rent increase is "excessive"—meaning it far outweighs the fair market value for equivalent properties in the same general area, or the property's condition has deteriorated—they possess the statutory right to challenge the increase.

To challenge a rent increase, a tenant must apply to the NSW Civil and Administrative Tribunal (NCAT) within 30 days of receiving the 60-day notice.

When ruling on whether an increase is excessive, NCAT will evaluate:

• Market rents for comparable premises.
• Enhancements or repairs done by the landlord (or lack thereof).
• General condition and age of the property.
• Any reduction in the tenant's amenities or services.

If NCAT finds the proposed increase excessive, it has the power to issue an order setting a maximum rent for up to 12 months.

Keep Rent Cycles Compliant

With rent restricted strictly to 12-month gaps, estimating when the exact optimal time to enact an increase is crucial so you don't inadvertently break the law.
