Serradigitus gertschi, for sure, especially considering OP's locale.
This species prefers rocky cliffsides, and is generally only found on vertical surfaces, hiding within the cracks and crevices by day. Keep on the dry-side, and provide lots of vertical things to climb on- stacking flat stones in a manner that creates 1-inch crevices is a great way to make them feel at home.
They behave extremely similar to Centruroides (bark scorpions), even sharing the communal behavior; you can house hundreds of them in the same enclosure, with no fights or cannibalism breaking out. Most specimens found inside homes or away from cliffs are wandering males, of which have dispersed to search for females.
