   Hard to sell a job that way. Customer is convinced it needs footers. He won't go for a brick under each corner. Though it is probably all it needs.

   I started a patio cover off the side of my house. I went down to the building dept. and they gave me a handout for a patio cover. In my area (just above Denver) they recommend a pier footer under every 4x4 that is 10" across by at least 30" deep.

   that sounds about right but you might want to go a little deeper depending on how deep you frost line is where you live. you want to get below the frost line because it will lift the footers out of the ground.

   You have to check with your AHJ to get a definitive answer. Generally, the depth is = to the hundred year frost line.

   Generally, the size depends on the farthest distance between rebars. Reinforcing steel should be covered with 3" of standard concrete or 2" of water resistant 'crete.
