It's a wolf spider. When they end up in your house they messed up and accidentally wandered in there. They generally stay outside and make webs that look like the funnel webs that funnel web spiders make in bushes and crevices. They are all over the place by me. Mostly outside around my house and where I work but sometimes I find one inside and they freak out and run away when I go near them.

They are big and creepy but they shouldn't harm you. They are not aggressive.
