It's an automatic sprinkler system with a neatness challenged supervisor.

Looks like a Steatoda (by the appearance), and all those irregular egg sacs support that ID. Probably Steatoda grossa. Not a danger to humans.
If it were the other option, a Latrodectus hesperus (the Black widow found in Northern California) the egg sacs would be smooth and uniform, usually kind of tear-drop shaped.
So Steatoda wins.
