Dear Client,
Your spider is called a California tube trapdoor spider, Calisoga longitarsis . While it is closely related to the tarantulas, it is sometimes called a false tarantula. "These spiders live in burrows. Some finish these with a hinged door. They often push this door up and wait for passing prey. When they catch it they try not to leave their burrow. Sometimes a burrow has a side tube. It is not certain whether Sinopesa builds burrows."

Overall, spiders are considered beneficial organisms as they feed on other insects. When they get into homes they are more of a nuisance. I would gently capture then release this spider outdoors.
Hope this helps!
