The answer

Yes. Calgary requires a tree protection plan when development or construction activity occurs within six metres of a public tree. Root zones, excavation, equipment access, material storage, pruning, hoarding, street use, private trees, design, construction staging, and written authorization can affect scope and timing.

Calgary-specific context

A mature boulevard tree can influence driveway, servicing, excavation, crane or material access, and the buildable concept even when it is outside the title boundary.

What to do next

Inventory public and private trees before final concept design or site-access assumptions and obtain the required arborist or City pathway.

Compare the builder, lot and total cost.

Ask for the complete contract, deposit protection, inclusions, GST treatment and delay terms before paying. A nearby permit or a showhome is not proof that your home or its amenities will be completed on schedule.
