With rents in South Australia rising nearly three times faster than non-housing inflation, SACOSS is proposing a cap on rent increases for existing tenancies at the rate of the Consumer Price Index (CPI). This reform aims to protect low-income renters from being priced out of their homes, while still maintaining a fair return for landlords. Unlike a rent freeze, this “third generation” rent control model provides stability for tenants without distorting the market, and complements existing reforms and housing supply efforts to address the state’s worsening rental affordability crisis.
