Olios giganteus is very common in Arizona. Here is one watching me watering at the bathroom sink. The phone and my hand are only a few inches from the fuzzy little thing. This is a small one.
They are known as crab spiders because when the leg is extended, that's what they look like. I enjoy them in the house because they eat other arthropods. I've never been able to get close to touching one, and never been bitten.
