A package of significant reforms targeting NSW's overheated rental market will become law by the end of the year if the government gets its way in a system "rebalance".
A government discussion paper released on Friday proposes measures beyond the Minns government's previously promised rental reforms to end no-grounds evictions, allow more pets in rentals and introduce a portable bond scheme.
The measures include a public database of rent increases, closing a loophole allowing multiple rent hikes a year and mandating a free way to pay online.
It comes amid a sustained rental squeeze that has pushed the median rental price for a unit in Sydney to $670 a week.
About a third of people in NSW are renters.
Better Regulation Minister Anoulack Chanthivong said the new proposals were part of a model that would prevent "excessive" rental price increases.
"This is significant reform and that's why we want to work constructively with both renters' advocates and property advocates to ensure we can get the balance right," Mr Chanthivong told reporters.
Public consultation will run until August 11, with the government confident it can pass reforms through parliament by year's end.
Without opposition backing, the Labor government needs support from at least two crossbenchers and six in the upper house to pass legislation.
In the meantime, the government's previously promised measures, such as a portable bond scheme, were moves to "take the heat" out of financial pressures on renters, Mr Chanthivong said.
According to the discussion paper, cracking down on "excessive" increases could mean the government collects rent-rise data and makes it publicly available by requiring landlords or their agents to report rent increases, or gathers rental information voluntarily.
Another rental affordability measure could be achieved by requiring a landlord to prove a rent increase was not excessive where, for example, a rent increase exceeds inflation across a certain period, the discussion paper says.
In June, the government was forced to ditch one of its promised rental reforms - banning secret rent bidding - after landlord and tenant advocates warned it could make market conditions worse.
However, laws to allow tenants to transfer bonds from one property to another and a ban on real estate agents and landlords soliciting rent bidding passed the parliament.
The Greens, who have been calling for an immediate rent freeze, supported action to make renting more affordable and secure.
But any action on excessive rent increases needed to include longer-term rent controls, such as a clear limit on what a rent increase can be, renters' rights and housing spokeswoman Jenny Leong said.
"The Greens and renters are ready to fight the powerful real estate and developer lobby that will no doubt be ready to stop reforms from undermining their profits," she said.
