How SA rent increases work
SA rent increase rules are governed by the Residential Tenancies Act 1995 and administered by SA Consumer and Business Services (CBS). The 1 July 2024 reforms moved SA from a 6-month frequency cap to 12 months, aligning with most other states.
What the notice MUST include
- Tenant name(s) and rental property address
- Current rent and proposed new rent
- Effective date (at least 60 days from service)
- Landlord or agent name and signature
- Date the notice is served
SA-specific quirks
From 1 July 2024, SA moved from a 6-month frequency cap to 12 months. Earlier 6-month rules no longer apply. The CBS template is recommended but not mandatory.
Fixed-term vs periodic agreements
During a fixed-term agreement, rent can only be increased if the agreement provides for it. Periodic agreements follow the 60-day notice rule.
Common landlord mistakes in SA
- Increasing rent every 6 months (no longer permitted post-1 July 2024)
- Serving fewer than 60 days notice
- Failing to specify the effective date in writing
- Forgetting to record proof of service for SACAT disputes
Common questions
Did SA really stop 6-monthly increases?
Yes - from 1 July 2024 the frequency cap is 12 months. Earlier increases scheduled under the old rules are unaffected.
Is the CBS form mandatory in South Australia?
No - the CBS template is recommended but not mandatory. Any written notice with the required content is valid.
Who hears SA rent-increase disputes?
SACAT (South Australian Civil and Administrative Tribunal). Tenants can apply within 30 days, with longer windows in exceptional cases.
Can a tenant challenge the rent itself if it is excessive?
Yes - SACAT can review the new rent against market rents for comparable properties. Excessive increases can be set aside.
Does SA allow electronic service of the notice?
Yes - if the tenant has consented to electronic service in writing. Keep proof of delivery.
Are there extra rules for student housing or boarding?
Rooming accommodation and student housing have separate rules under different parts of the Act. The 60-day general rule does not always apply.
