Shall canopies attched to building include in building footprint

I imagine the canopies are simply a "roofed over area". If that is the case then it should not be included in the building footprint.

Canopies are usually not considered part of the building footprint. Most projects use the "building envelope," or the shell of the building to define the footprint. LEED defines the footprint as "the perimeter of the building plan" but that still leaves some situations unclear. In many cases the building plan is the same as the boundary of occupied or conditioned space, but in hot climates this can get harder to define since many occupied spaces can be open to the outdoors. Since the area under a canopy or awning is usually not enclosed space, you probably wouldn't include it in the building foot print. Sometimes you'll need to use your best judgement to define what is "inside" and what is "outside."
