Hi, this looks like a male Triangulate Cobweb Weaver, Steatoda triangulosa.

TangledWeb

If you have old wood siding under vinyl they may live in the rotting wood. There are insects to eat in old wood. In the cold weather they might find ways in through construction junctions. They can kill other spiders in your house. They’ve killed almost all of the Pholcus phalangiodes in my house and took their web locations. I think P. phalangiodes wasn’t native anyhow. The S. triangulosa hide most of the time and avoid my pets, so I’ll let them stay in the house.
