Common House Spider, Parasteatoda tepidariorum. 🙂

Brown Widows (Latrodectus geometricus) have distinctive egg sacs, they’re spiky little balls. Parasteatoda also have distinctive egg sacs, a brown papery teardrop shape as depicted here. There are two species of Parasteatoda in North America, the other is Parasteatoda tabulata which is less common and known from further north, due to it’s similarity to P. tepidariorum however it is possible that it’s range extends further than what is known but if your spider were that one I’d expect to see a more pronounced scalloped white line on the abdomen. Here are Brown Widow egg sacs for comparison: https://bugguide.net/node/view/1143027/bgimage
