Hi, and welcome to the site. Your little fiend is a female southern house spider, one of the crevice weavers in the family Filistatidae, Kukulcania hibrnalis species. They are not known to bite, not aggressive. A long lived spider, these females have been known to live 8 years in captivity.
Yes …. this is a Southern House Spider (Kukulcania hibernalis), filed. 🙂 Welcome to Spider ID.
