It is the hybrid Fiddle-Black Widow.
There was a LARGE wolf spider in the kitchen sink here at work this morning.
I can't help you with what type of spider you have there. I would bet there is a web site that has a list of typical house spiders in your area. The vast majority of house spiders are harmless to humans. Around here only the black widow & the brown recluse also called fiddle back are harmful.
