Arizona chicken lovers, share your setup?

I am so interested and excited to discover if chickens could be an addition to my menagerie. I am considering whether there is a spot in the backyard that would be suitable for a chicken coop and run (south facing yard with lots of shade). My thought is that a run could be fastened to the metal laundry line, or wall (first photo) and their coop could possibly be situated somewhere near the small tree on the right side of the second photo (the turf is no longer there, I tore it all out). I am trying to grow more grasses throughout the yard but it is taking some time since the soil is poor due to the turf. These photos are from last year so there is more grass for the tortoise (he free roams the backyard--desert tortoise).

I would love to see any other setups folks have in Arizona if you feel like sharing. Or if you have general advice or ideas on a good setup for 3 chickens. The last photo is the other side of the yard and doesn't seem ideal but open to suggestions! I am a newbie, but I am a Zoologist (insects are my specialty).

I appreciate any advice you may have for me. I am in Tucson, AZ.

Thank you!
