Spider found on transit case from California. Approx 1 1/2 inches leg span. Is it poisionus?

It looks a lot like a Kukulcania hibernalis, or southern house spider. This one appears to be a female and if it were to bite you then it would be painful, but not dangerous. These spiders typically keep to themselves so unless you find one hanging in a really bad place it's better just to leave them alone.
