A number of Toowoomba councillors are backing the move to limit the number of units developed in a street.
Council will make their decision at an Ordinary Meeting to be held next week.
The move comes after concerns surrounding the growth of units in low and medium density areas.
Cr Nancy Sommerfield says having too many units in one street puts pressure on the Councils infrastructure.
In particular Cr Sommerfield pin-pointed the areas of Wyreema and Cambooya where she says there is duplex after duplex being built on a street- there should only be so many duplexes on one street.
