"Decaying" old apartment buildings around Melbourne could be demolished and sold to developers under proposed reforms that could see people's homes forcibly acquired.

As it stands, any plan to sell a building must be approved by 100 per cent of owners, making sales of ageing apartment complexes near impossible.

The Andrews government is considering reforms that could result in the voting requirement for sales and redevelopments reduced to as little as 75 per cent.

While these laws would likely see the replacement of many old "six-pack" blocks built in the 1950s to 1970s in desirable suburbs such as Toorak and South Yarra, there is also concern it would force people to relinquish their perfectly liveable homes at the bidding of their neighbours.
