South Australian tenants will be protected from so-called 'no cause' evictions under rental reforms proposed by the state government.

Landlords would be prevented from ending tenancies or stopping fixed-term leases unless there have been breaches by the tenant, or they are planning to sell, renovate or take over the property under the proposed changes.

The government also wants to double the notice period to end tenancies to 60 days.

Consumer Affairs Minister Andrea Michaels said the proposals would help address the severe rental shortage in the state.

"I've heard stories about people who've complained about a leaky tap and when their 12 month lease is up, they're out," she said.

"Those sort of situations will end if this legislation passes parliament and gives people that security."

Joe Aylward from tenants advocacy group SYC said his organisation is receiving more than 1,000 calls a month from stressed renters facing homelessness.

"One of the biggest themes we get are people who are given 28 days notice in terms of their fixed-term lease to vacate the premises," he said.

"That's a completely unrealistic notion at the moment in a market when the vacancy rates are less than 1 per cent."

Better Renting deputy director Bernie Barrett welcomed the changes, which the group had advocated for, but called for more action on "unlimited and unreasonable rent increases".

Ms Barrett said the announcement would "provide renters with a greater sense of stability in their homes".

"It's also great to see that this will ban no cause evictions at the end of a fixed-term lease, which is where many renters experience no cause evictions," she said.

The changes come as South Australia experienced a record low vacancy rate of less than 1 per cent, and follow other recent rental reforms planned by the state government, including removing a blanket ban on pets in rentals and banning rent bidding.

Joseph Slattery said he was "pretty lucky" with his current property but had seen friends and family struggle to find a place.

He said abolishing no-cause evictions was "fair enough".

"I don't think you should be able to be evicted for no real reason just because they may want to put up the rent," he said.

However, Opposition Leader David Speirs said the measures would "contribute to landlords leaving the rental market".

"We've got a rental crisis in South Australia and that's around availability of rentals and access to rental property," he said.

He said while it was important to have protections in place for renters, he felt the current balance on periodic and fixed leases was "reasonably good".

"There's no doubt that this latest reform will put people off offering their properties up for rental and as a consequence the rental crisis will get worse," he said.

Mr Speirs said he wanted to see better tenant advocacy to help renters speak up when negotiating with landlords over rules "that could discourage landlords from entering the market".
