Gravel under footings?

Seems to be a lot of opinions on this. I've always put a couple inches of gravel under footings but curious what you guys think.

No expert but I'd think it would depend on the soil conditions. Around here the footers are normally poured directly over the dirt or slate rock.

Yes, it all depends on the site. Footers in my area are usually poured right on top of soil that's of the right compaction. Crushed stone is only used when poor soil must be removed and is back filled with stone to cut down on the amount of concrete needed.

The 'footing' part (under the Sonotube)... is this usually poured as one piece with the tube? Or poured first, then let dry, then do the tube... as 2 pieces.

It depends on your application. Sometimes there is a footing and sometimes there isn't. For most simple deck projects the Sonotube is just dropped to the bottom of the hole and filled and there is really nothing below the tube except hard, virgin soil.

Well let's suppose a footing is needed.

Then it will depend on your inspectors and whether or not they want to inspect the footers.
