Domestic house spider (Tegenaria domestica)
Domestic house spiders have become distributed all over the world thanks to human activities, frequently living in and around houses. They're medium-sized, agile spiders that spin funnel-shaped webs in dark, undisturbed places.
Like many other species in their family, they're covered in feathery hairs. I gently rubbed a few off this spider's abdomen, which you can see along with other photos on his BugGuide page:
