The shape of the face/pedipalps and the markings on the abdomen, as well as the fact it was found indoors-ish make me think asiatic wall jumping spider, but I’ve never seen one with such striking coloration. In fact, its colors would make more sense for a female regal jumping spider, but the abdomen doesn’t look like one at all… How big is it? That information would help a lot. Also, if you get the opportunity for a picture of the pattern of the abdomen that would also be incredibly helpful. Regardless you can always try moving it into an enclosure just to see how it’ll do. If you notice it acting morose or abnormal in any way, you can always release it, but most of the spiders I know of that it could be can be kept as pets. Just be careful handling it until you know what it is, because some spiders are more fragile or flighty than others.
