The Toowoomba Regional Council has taken major steps to prevent duplex clustering by forcing developers subdividing land to nominate and limit the blocks that will be allowed to have duplexes built on them. Since 2012, Duplex's have been an exempt development which has resulted in an increased rate of construction, and many being a poor design standard and whole streets and sometimes entire developments being cluster housing. This has impacted on local streetscapes and neighbourhood character and amenity. These areas aren't always adequately serviced to meet the needs of the increased population
