Can my landlord raise the rent in SA?

Yes, but only once in 12 months, with at least 60 days' written notice.

Your clock

• 60 days, written: Notice
• 12 months: Between rises
• Within 90 days of the notice: Challenge at SACAT

The rule in SA

• The first rise can start 12 months after the tenancy began.
• Later rises cannot come within 12 months of the last one.
• In a fixed term, rent can only rise if the lease has a rent-increase clause.
• There is no cap, but SACAT can declare a rent excessive and set a maximum for up to a year.
• A lease signed before 15 January 2026 can keep an automatic rise written into it, on the dates it sets.

Even a rise you agree to cannot start within 12 months of the last one.

What to send

I received your rent increase notice dated [date]. Please confirm 12 months have passed since [date] and that I have 60 days' notice.
