Development Services staff have geographically divided Markham into three major Development Districts (West, East & Central) to create a more efficient and effective structure for its overall operations. Special Heritage Districts corresponding to Markham's designated heritage areas have also been included and can be found within all of the major districts.

District Teams include staff from various departments and divisions within the Commission including Planning, Engineering, Urban Design, and Heritage.

Each team has in depth knowledge of activity within their districts and is responsible for all development applications, studies, special projects, and general inquiries regarding development in their district.
