Hello, welcome to the site. This will be quite important in determining which spider this is; do you have a picture that shows the cephalothorax in more detail?
As it stands, this is either a Brown Recluse Loxosceles reclusa or a male Southern House Spider Kukulcania hibernalis. One is very medically significant, one is not. If you were bitten you should seek medical treatment immediately.
I see more male southern house spider in this if I am getting those prominent peipalps correctly.
One of my little friends:
Yes, this looks like a male Southern House Spider (Kukulcania hibernalis). Filed. Welcome to Spider ID. 🙂
