Hi, this is Steatoda nobilis, a Noble Cobweaver. They are related to Brown Widows in that they are in the same family, Theridiidae. Yours is one of the cobweb spiders commonly referred to as False Widows. It isn’t anything to worry about, its venom is far less potent to humans than the True Widows. Steatoda spiders live in many houses and storage areas. You can recognize yours by the marking on the abdomen that looks like a head in a hood, or a skull sometimes.
